2018 RAM 2500 Service Brakes Problems

Anti lock brake control has failed twice and then afects cruise control and warning bell continues to ring paid to have fixed twice and still no factory fix .it hs been on recall list for years now!

I own a 2018 Ram 2500 equipped with the 6.7L Cummins diesel engine that I purchased brand new in Iowa. For approximately the last four to five years, my vehicle has displayed persistent warnings including “Service Electronic Braking System,” ABS warning light, and traction control warnings, accompanied by constant audible alerts. As a result, multiple braking safety systems are disabled, including anti-lock braking, stability control, traction control, and cruise control. For several years I contacted Ram dealerships and the manufacturer regarding this issue and was repeatedly told that repair parts were unavailable. During this time, widespread reports of identical failures were being discussed on owner forums and among dealerships. A federal safety recall was eventually issued for the ABS control module, and I received my official recall notification letter approximately one year ago. Despite the recall being active, the manufacturer and local dealerships continue to state that no replacement parts are available and that there is no estimated timeline for when a remedy will be provided. As of today, my vehicle remains unrepaired and continues to operate with disabled braking safety systems and constant warning alarms. This is a heavy-duty truck that is regularly operated in Iowa, where inclement weather conditions including snow, ice, and heavy rain are common. I am concerned about the safety risk posed by operating a vehicle with compromised braking and stability systems and the lack of any available remedy after more than a year under an active safety recall. I am submitting this complaint to document the ongoing safety defect, the prolonged lack of remedy, and the manufacturer’s inability to provide a timeline for repair of this federally recalled braking system.

Service ABS light constantly alerting, every time I touch brakes. Loses cruise control. I called two local dealerships who tell me parts are unavailable. This is on recall, why aren’t parts available?

The manufacturer has had a recall out since November 2024. It is now Jan 2026 and no word from the manufacturer when the parts will be availiable. My truck continually gets an ABS warning. I have contacted the dealer several times with no help. I believe the recall should have been address sooner than this.

Abs and traction control goes off and on randomly

Abs and traction control showing error and alert all the time.

I recieved a recall ncotice # 24v-896 on my vehicle over a year ago and there is still "no parts available" to fix it. The break HCU needs to be replaced. This is a huge safty concern!! The brake system in my vehicle has become more and more unpredictable in the past few months.

See attached document for complaint.

ABS and Electronic Braking System. I have not been able to use cruise control because this problem with my brakes also disabled my cruise control. I worry about my brakes failing. The part(s) needed to repair this have not been made available so I've been advised to not have it serviced until repair parts can be made available. I have had warning lamps light up on the dash since December of 2022. It's been over three years and RAM is not handling this in a timely fashion. I'm concerned about my brakes failing.

My ABS light keeps coming on in and out over the last 6 months. The dinging is equivalent to NOT wearing your seat belt. Dealer said it was a recall since 12-2024. There is still not a remedy for this. I was told I could pay for an aftermarket product for about $1000 and when parts became available they would do the repairs and pay me back for the repairs I have paid for. I told them I wanted that statement on paper and was told to contact corporate. They told me exact same thing. It's been over a year now since the recall has been issued shouldn't that be enough time for them to figure this out since it has to do with your brakes not working properly? This is a safety issue and needs to be fixed ASAP!

A recall was issue 1 year ago for the issue below. This issue has yet to be resolved. The dealer informed me they could fix it at my cost but left little or no hope for the reimbursement. One year is sufficient to come up with a fix. I have constant alarms going off on my truck which is very distracting. I have parked my truck as it poses an unsafe condition. Manufacturer Recall NumberC4B NHTSA Recall Number24V-896 Recall StatusRecall Incomplete, remedy not yet available Summary Some (2017-2018 MY Ram xxx) vehicles may have been built with a brake hydraulic control unit ("HCU") that is susceptible to failure or malfunction which may result in a reduction or change of Anti-Lock Brake System ("ABS")/Electronic Stability Control ("ESC") /Traction Control performance. A failing HCU will initially result in the intermittent loss of ABS/Traction control progressing to permanent loss. Safety Risk The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning.

Recall/Campaign: Ram/Stellantis C4B Problem: “Dealer says remedy/parts are not available / cannot schedule recall repair.” This has been a problem since 2023. Have not had ABS for years or 4x4 and i live in a snow environment. My breaks and rotors are trash from not having ABS.

I do not feel this recall - considering it is regarding BRAKES - has been remedied in a timely fashion. It started over a year ago. They obviously are not interested in addressing the fix. I assume they are taking the hit and paying off lawsuits as it is cheaper than actually completing the recall. But whatever the reason, they have not addressed this and my RAM repair location keeps telling me "parts are not available" to fix it. A recall was issued but it does not appear it has any teeth. What is the point? Please let me know if any action is imminent. It can also potentially effect the transfer of title if I chose to sell the vehicle. Thank you for your attention to this matter.

My 2018 RAM 2500 has had an ABS system recall since Nov 2024. My truck has had a problem with the ABS since 2019. I do not have anit-lock brakes or cruise control as a result of this failure to be able to resolve the problem. Over a year since the recall, and still no parts available. How long is the NHTSA going to let RAM get away with this?? Maybe after some has an accident or hurts someone they will respond. I have been a RAM owner since 1989 since the first CUMMINS engine was put in their 2500's. I'm VERY disappointed in RAM, and the NHTSA for not resolving this.

I am the owner of a 2018 RAM 2500 that is subject to NHTSA safety recall 24V-896 (manufacturer recall C4B), involving a potential failure of the Hydraulic Control Unit (HCU) affecting ABS, electronic stability control, and traction control systems. This recall has been active for over one year on my vehicle. Despite repeated contact with authorized RAM dealerships and the manufacturer, I have been informed that no repair remedy or replacement parts are available, and no timeline has been provided for when the recall can be completed. This is a brake-related safety recall, and the continued inability to repair the vehicle creates an ongoing safety risk. The manufacturer has not provided an interim remedy, loaner vehicle, or alternative solution. I am filing this complaint to document that the recall remains unresolved due to parts unavailability and to request NHTSA review of the extended delay in providing a safety remedy.

I am forced to drive a vehicle through the winter with a known safety defect - an ABS system that does not work properly. I was told by Ram corporate they were trying to source parts - it has been several months and still no resolution. I was told I could rent a car at my expense to drive in the winter, or try and find the parts to repair and do it at my cost. They are obviously trying to avoid paying for the repair, and putting me and my family at risk.

The recall has been active for over a year without repair authorization due to no parts being identified.

After several visits to dealership, I have been told I am not able to get this recall remedied. I am stuck with a vehicle that is unsafe to drive, according to the Dodge dealership and unable to be traded in. I am now having a financial loss as I pay for rent on my RV and am unable to pull it due to the faulty part and safety concern. The ABS indicator and traction control light is lit on the dash. This started about 6 months ago. Periodically, I believe the brakes are failing as I can feel it on the front end. The cruise control no longer works on the vehicle and a buzzing sound comes on while driving. The warning indicators have been confirmed through the dealership mechanic and code readers. The staff at all dealerships I have visited have been of no assistance and virtually told me I am just out of luck. I commute to work and travel for pleasure. As an older individual, I do not have the financial means to take the loss on a vehicle and just buy another. How does one take a $60k loss like this because Mopar has not fulfilled their commitment to provide quality parts and remedy a safety recall?

I have had this issue for over 2 years now and the recall is almost a year old. I went to the RAM dealership in Elizabeth City, NC and they have told me that they would get back to me for over two years. I call MOPAR and they still have no fix for the issue nor do they have a timeframe of when to expect. When asked, if they are going to cover the cost of the accident that occurs when the brakes actually fail, they suggest if I am not comfortable driving the vehicle, they might offer a rental vehicle. I go through that process and since they don't have an estimated timeframe, they won't allow me to get a rental. Just need to problem fixed and they have had plenty of time to correct this issue.

MY ABS module was replaced shortly after purchasing my truck, which currently has 65,000. However, the ABS module has been malfunctioning for years. Despite contacting and visiting dealerships, I've been informed the necessary part is unavailable. consequently, my truck has been without traction control, and I've been unable to use cruise control, for most of the time I've owned it. Recently, I've experienced loss of traction, which has nearly resulted in three accidents. while I understand the concept of recalls, this situation is unacceptable.

Warning lamps for braking systems are active. Recall C4B has been active for over a year now with no remedy.

The brake system and steering system are affected. Both are subject to open safety recalls that have not been fully resolved. The vehicle is available for inspection upon request. Unresolved brake and steering issues pose a serious safety risk, particularly when driving with my family. A failure or malfunction of either system could result in reduced stopping ability or loss of steering control, increasing the risk of an accident. Due to these unresolved safety concerns, I do not feel safe operating the vehicle. The issues are associated with acknowledged manufacturer recalls. However, my local dealership/manufacturing has failed to adequately respond or complete the necessary repairs, despite multiple attempts to address the problems. The vehicle has been presented to the dealership for recall-related concerns. No inspections by police or insurance representatives have occurred to date. Manufacturer involvement has been limited to customer service communications, without resolution. Symptoms include ongoing brake and steering concerns that prompted recall notifications. These issues have persisted despite recall availability and were present prior to my most recent attempts to obtain service. No effective corrective action has been completed.

Continuing saga of HCU failures. First identified years ago, i follow up with dealer monthly. Latest call last Friday, they advised no solution or timeline for repair provided by FCA. Impact is loss of ABS (reduced braking safety), loss of control of trailer electronic brakes (increased risk while towing a trailer), incessant audio warning alarms (distracts driver), and loss of other systems (cruise control). First detection of malfunction was spring 2024. My fear is FCA/Stellantis are not doing their due diligence to preserve the safety of their customers muchless of our highways. All documentation of the problem is based on personnel research and verbal communication with the dealer service department. I do have maintenance records identifying the problem with my vehicle if needed.

ABS / HCU failed. It was recalled a year ago but still no parts / remedy available. It needs to be fixed. A year is a ridiculous amount of time to have no fix.

Hydraulic Brake controller has been under recall for over a year with no remedy. Unacceptable and dangerous at this point. When will action be taken against Mopar and chrysler?

ABS warning/Traction Control lights and warning chime activation...for over 9 month...

Early 2024 and it continues today, I randomly get an alert about my braking system needing checked but then the message will go away and everything works fine. I finally took it to Keer Automotive dealership in New Lexington OH in March 2024 to see what was going on and they advised there was an issue with the ABS module and the part wasn't available but they were expecting it in May 2024 and it would cost about $1800 for the repair. They put me on their list to contact when they received the parts. Around November 2024, I received a recall notice. To date, I am still waiting on the part. I continue to follow up with Keer but they have no answers. In the meantime, I am stuck with a $65,000 truck that has a faulty braking unit. It is my mode of transportation and with winter upon us once again I am faced with winter weather driving and not knowing if my brakes will work properly. This puts me and anyone riding with me at extreme risk of an accident as well as anyone around me that could be impacted should an accident occur.

1 day after purchasing from Dealer random ABS warnings started disabling the ABS, Cruse Control and Stability control. Researching issue there is a recall from 11/2024 Recall was not disclosed. the remedy is to replace the HPU which is not available for the 2500 series pickup. which appears to be the same HPU that is available for larger trucks. Parts availability is not timely for such a critical component.

Reference 24V-986. This recall shows a date of November 2024. The remedy for this is not yet available as of 12/08/2025. It is winter and as there is no ABS on my truck I cannot use it for work or personal reasons. This is unacceptable. I will not purchase another FCA vehicle again due to the lack of customer support.

Constant cycling of ABS and Traction Control lights with tones. Causes ABS, Traction Control and cruise control failures with persistent tones and lights. Parts not available after 12 months of open recall.

Stellantis and RAM companies have had Manufacturer Recall NumberC4B NHTSA Recall Number24V-896 Recall Status: Recall Incomplete, remedy not yet available This has been well over a year and I have lost the use of my Truck for loading my Truck Camper for the entire year due to their lack of resources allocated to fix this issue. I have had the Traction control light /ABS Service light associated with the HCU electric pump motor fail on this recall since June of 2024 and it is due to defective parts that do not last as this was the second HCU/Electric pump motor in the truck from the Manufacturer and installed serviced by my local RAM dealer dealer( first one failed at 11,500 miles approximately. my truck has 23,000 miles on it currently as and when the repair part(s) come into stock, it will be the 3rd unit installed. This time on waiting for upgraded parts to be installed under the Recall/Warranty is unacceptable and is not "TIMELY" at all. Additionally if this light comes on during driving with cruise control on it will shut off cruise control and can cause an accident from the deceleration.

The Brake Hydraulic Control Unit (HCU) covered under Safety Recall C4B has been unavailable for several years, leaving my 2018 Ram 2500 with ongoing ABS, traction control, and electronic stability control malfunctions. This defect has already caused an actual accident. In January 2024, during snow conditions, the ABS and traction control failed while I was braking in my driveway. The truck slid uncontrollably and struck a tree, causing over $10,000 in damage that had to be repaired through my insurance. This incident occurred specifically because the brake and stability systems did not function properly. The issue continues to create serious safety risks, especially in winter. The warning lights for ABS and traction control are on constantly, accompanied by continuous dinging that is extremely distracting and stressful to drive with. The truck loses stability on snow or ice, braking distance is increased, and the vehicle behaves unpredictably. I am now driving again in snow and ice this winter, and I am genuinely afraid this defect will cause another accident. Despite this being an acknowledged safety recall, every dealership I contact says the replacement HCU part is still “not available” for my vehicle. This has been confirmed repeatedly by multiple dealerships and by the manufacturer’s recall hotline. I have attempted to get this recall repaired for several years with no success. Because the recall remedy is unavailable, the vehicle remains unsafe to operate, yet I have no alternative transportation and must drive it daily. I also cannot sell or trade the truck, which has caused significant financial harm. I am requesting NHTSA assistance because the recall remedy has not been provided within a reasonable timeframe, the vehicle remains unsafe, and the defect has already contributed to a crash.

Please add this to complaint number: 11702732 This is a supplemental complaint regarding the same safety issue I previously reported involving Safety Recall C4B on my 2018 Ram 2500 - complaint # 11702732 In addition to the safety concerns and the prior accident I described in my original complaint, the unresolved recall has also caused significant financial harm. I still owe approximately $15,100 on the vehicle and must make a $515 monthly payment. Because the recall remedy has been unavailable for years, I cannot legally sell or trade the vehicle, even though it should have substantial equity. The truck’s resale value has dropped due to the open safety recall with no remedy, leaving me financially stuck with an unsafe vehicle I cannot get rid of and a high payment that I currently cannot afford due to job loss. The unresolved recall continues to put me in danger during winter driving, and the lack of remedy has created both a safety crisis and a serious financial hardship. Please attach this information to my previous complaint for the same VIN.

The C4B recall on my truck has been open for over a year and Ram / MOPAR just keep saying no part available when I take it in to get fixed. The truck will not stay in cruise control every time the light dings. It is a hydraulic controller for the brake fluid which seems like it is a huge safety risk if it does fail while driving.

Traction Control and ABS not working properly. ABS light on dashboard is on called dealer several times and am told that the parts are unavailable. However, they said if I want to pay for the parts they could fix it. We called mopar and were told that the parts are available and can even be purchased on [XXX] . Called and explained this to the dealer and they said they had 1 in stock and made an appointment. Then received a call that they didnt know if they could get the parts - seems like if I want to pay out of pocket they will fix it. I would like to know if I lose my brakes or have an accident because of this safety issue who will be responsible?? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Recall #24 V896000, C4B was issued in December of 2024 . Recall was to replace the HCU unit that controls the braking system. I have called every month, no parts are available to fix the problem. Warning lights and sounds are now going on and off on the vehicle. It does not seem reasonable that parts are not available to fix a safety recall for one year. Please contact the manufacturer to force them immediately to get this severe safety issue fixed.

Service ABS light constantly is on and off with dinging and kicking cruise on traction control off. I feel this isn't safe with my children on car. It has been a year I feel this is plenty of time to make it right or replace my vehicle

My 2018 Dodge Ram 2500 ABS Hydraulic Control Unit failed, almost a year after recall NHTSA 24V-896 (manufacturer recall C4B) was issued. This resulted in a loss of ABS capability. I reached out to the closest Dodge dealers and they informed me that a replacement component was not available. As this was a safety concern, and no resolution was available through Dodge, I was forced to complete the repair myself. Interestingly, I had no issue purchasing a Mopar OEM HCU. After replacing the unit, I'm no longer receiving ABS error codes and the truck is functioning normally. After submitting a reimbursement request to FCA for the repair via their website, my request was denied as I didn't use a certified repair facility. I informed them that I had tried but that they informed me that no repair components were available to complete the recall.

My ABS module has an active recall. I have replaced brakes and rotors in the front and rear. I have had to resurface my rear rotors due to the issue. My breaks are locking up and causing issues. I can't back up my trailer without my breaks locking up. The recall has been active for almost a year without a resolution. This problem is unsafe and people's lives are at risk. Something needs to be done. I can't even buy an aftermarket updated part to fix this issue. Thank you!

24v896-unit has been coding for months, dealership or chrysler have no fix in site. this is a safety hazard and I need my unit for daily driver and have been without for more than 3 months with no solution. I need them to replace this unit with a new unit or buy it back for the price of what it would cost me to get a new one. I need to have a truck to use if they are not going to repair it. I need this now.

abs and traction lights stay on. cruise control does not work. recall is 24V-896 and parts are still not available after almost a year.

My vehicle has a recall for a an ABS control module which affects, the ABS system, traction control, and cruise control system. The cruise control system will randomly turn off when the vehicle is at highway speeds causing a momentary struggle to keep control of the vehicle. The driver information display in the gauge cluster will randomly flash an error message with an audible "ding" which is highly distracting while driving. At times, this warning flashes every 3-5 seconds and lasts for 10-30 minutes at a time making it very difficult to concentrate on driving the vehicle. The traction control system fails when the message flashes which has been a problem on wet roads. The dealership has acknowledged the recall of the ABS module multiple times and indicated the manufacturer has not made a fix available for nearly a year. The issues with my vehicle are becoming more apparent and frequent every week. This is the second Ram 2500 I have owned that experienced a failure of the ABS module. I began to notice the issues with this vehicle in July of 2023 and the frequency has dramatically increased in recent months.

My traction control and abs brakes warning lights come on and off regularly. I do not have abs brakes or traction control a lot of the time

ABS failure light keeps popping on due to the recall. I have yet to get this resolved. The dealership wanted to charge $1200 and not fix the issue A DAY after purchasing. I have been dealing with this over a year. It is dangerous. I had to replace the entire transmission which cost $6,000 because the light will come on and stay on and send incorrect information to the computer system. The truck is not performing as it should due to this, and the traction loss is dangerous when braking suddenly.

Abs light and traction control light stays on plus keeps popping up to service electric trailers brakes. Electric trailer brakes well not work. Cruise control stopped working. All do to recall. Truck has had this recall for over a year now and I’ll I ever get told by dealerships that the parts are unavailable. Dodge makes this junk ass trucks everyday so I don’t understand why parts are unavailable.

Recall C4B/NHTSA 24V-896 Hydraulic Control Unit ABS. Continual tripping of the ABS warning resulting in loss of ABS, Cruise Control, Traction Control. Each trip give a warning and chiming resulting in nonstop alarms, noise and loss of the above features. It has been a year since the recall, over two years since the first class action and still no remedy to this safety issue. It is time for the NHTSA to sue and obtain a consent order from FCA similar to earlier FCA consent orders to repurchase these vehicles as they are currently unsafe to drive, there is no remedy in sight, and the resale value has plummeted as a result of this recall and lack of remedy.

ABS module/ HCU faulty. This has been replaced 2 times and lasts 3 years. Dealership says no fix has been made at this time for recall. No new parts to fix it, ABS light constantly going off.

Abs warning light dings and warning lights are on. Safety recall. When will this be fixed

I am concerned regarding the safety of this model and the hydraulic brake control unit/ ABS as I live in colorado it’s about to be snow season and my wife drives this vehicle to work on snow days. I’ve read the part failure can cause abs to fail and may lead to crash. Recall notice states no known remedy, and it’s been almost a year since the notice was issued.

Since the recall was announced, my truck has experienced constant ABS and traction control alarms, including an unending beeping warning chime that makes the vehicle unpleasant and unsafe to drive. My local Ram dealer confirms that the repair parts (HCU/ABS module) are not available and that there is no estimated time frame for replacement. This situation has now persisted for months, leaving me with: •A continuously beeping alarm while driving or idling, •A loss of confidence in braking and safety systems, •And a significant loss in resale value, since I cannot sell or trade the vehicle while this open safety recall remains unresolved. Impact This recall defect has made my vehicle effectively undriveable and unsellable. I have made multiple attempts to have it repaired, but the dealer and Stellantis representatives continue to tell me that parts remain on national backorder. As a result, I am deprived of the safe and normal use of my property. Under 49 U.S.C. § 30120, a manufacturer must provide a free and timely remedy for a safety defect. The ongoing delay and the lack of any interim solution (such as a loaner or disabling the alarm) clearly violate the spirit of this requirement and constitute a constructive deprivation of use. Requested Action I respectfully request that Stellantis: 1.Provide a functional remedy immediately (replacement HCU or equivalent). 2.If parts are still unavailable, provide a loaner vehicle, temporary compensation, or buyback option until the repair can be made. 3.Confirm in writing the expected date when replacement parts will be available for my VIN. I am filing a concurrent complaint with NHTSA to document this safety-related hardship and ongoing loss of vehicle use and value. Documentation Available upon request: •Copy of dealer service report indicating unavailable parts. •Photographs/videos showing active ABS and traction control alarms. •Records of my prior attempts to schedule service.

NHTSA Recall ID Number: 24V896, This recall has been going on for approx. one year with still no resolution to fixing the problem with the "Loss of ABS/Traction Control from Module Failure".

My RAM truck was recalled several months ago but has not been fixed due to no parts available for the fix. What am I to do? Dealers are no help at all. It has been almost 2 years since I have been trying to get this fixed. Please get RAM to get this recall done.

The recall was issued in November 2024 and it been almost a year and the part is still not available yet.

The ABS system continuously dings and the cruise control will not work and shuts itself off due to recalled defective part. Waiting for new recall part!!!!!!! Why was a recall issued with no part to fix??? Make them get their act together. This is dangerous and maddening to listen to constant bell ringing in the vehicle. Not to mention the possibility of an accident. This vehicle is my daily driver. I need the vehicle to be operational and safe.

Experiencing persistent ABS and Anti skid lights flashing on dash board along with persistent dinging, which has become very annoying. Took the vehicle to my nearest Ram dealership and they ran a diagnostic on it and told me that it was a faulty ABS/HCU causing the problem, but that there were no parts available to repair it. They said they would call and schedule an appointment to have it repaired as soon as the parts become available. I don’t know if I can wait much longer, as the constant dinging is very upsetting to my wife, who normally drives the truck.

Loss of control due to brakes locking up.

Going down a hill and had to do a hard brake for a animal and brakes locked up instead of gradually stopped causing me to slide Truck presenting a c0020 code

The ABS and and electric circuit lights came on, on the dash. Then a week later my Transmission started acting up. I had it into the shop and they are saying the 2 are related. They have given me the paperwork showing how the code that comes up is from the recall and the paperwork showing it can trigger the transmission control module. The manufacturer made the recall back in December of 2024. They have yet to come up with a fix. Now we have a none drivable truck that has to sit until they find a fix. I am still making payments on this vehicle and they have nothing to say. We are almost coming up on a year, where is the liability?

The recall for the ABS, C4B is still NOT resolved and is affecting other systems. I believe RAM headquarters are not interested in the repair. I have reached out and now they blocked me on social media because I complained publicly and posted the recall. They could at least replace with the same and it should work for awhile anyways. I just keep getting the same notice about it. PLEASE HELP

Recall 24V-896, cannot be repaired, no repair timeline in site, vehicle is coding and dealership has confirmed code. Driving cruise will turn off and braking system becomes difficult and unstable. Warning systems come one. Dealership attempted to repair but manufacture advised they were not allowed to do so because it would not be permanent. Dealership has advised to park unit and contact Chrysler for buyback. We have called Chrysler customer care daily for 3 weeks with no success and no end in sight. The will not provide daily driver solution, vehicle replacement or repair fix. This is part of our daily driver to and from work and to and from farm to carry trailer with cattle. It is unsafe without proper braking system functioning and dealership has confirmed this and advised us to not operate. Chrysler has also advised us to not operate since it has coded but has offered no options. Dealership confirmed code on or about 8/22/2025

Recall 24V-896 was announced on 11-27-2024. The recall states that this may cause an unsafe driving condition for the vehicle. Stellantis has not resolved this problem and states that the part is unavailable. Stellantis lists the replacement for the defective hydraulic control unit (HCU) part #68143491AB as available for purchase. This delay is unacceptable, with thousands of potentially unsafe trucks on the highways.

The contact owned a 2018 Ram 2500. The contact stated that while driving in reverse, down a steep boat ramp with the boat and boat trailer attached, the braking system suddenly malfunctioned, causing the boat, boat trailer, and the vehicle to go into the water. The contact had to climb out of the front driver's window and swim to safety. The contact also sustained a minor knee injury that did not require medical treatment. A police report was taken at the scene. A diving crew was called to retrieve the vehicle. During the incident, the vehicle was destroyed. The contact indicated that prior to the incident, the brake warning lights had remained illuminated, and also, previously, while driving, the brakes had failed and nearly caused a rear-end collision. The contact was informed that the remedy for the NHTSA Campaign Number: 24V896000( SERVICE BRAKES, HYDRAULIC) was not available. The manufacturer and local dealer were aware of the issue, but no assistance was offered. The contact indicated that the vehicle had experienced the same failure listed in the recall. The failure mileage was 180,000.

Mileage: 180,000

First, I was not involved in an incident or accident with my vehicle. My concern is for my safety in the future while driving this vehicle. My RAM 2500 Power Wagon has a safety recall C4B/NHTSA 24V-896 for the brake system but there are no parts available to fix it. I currently have an ABS caution light with a "Service Electronic Braking System" and "Service Automatic Braking System" that constantly flashes and dings at random. I took my vehicle in to my local dealership and they told me there are no parts available and they were unable to fix the ongoing problem. I asked if my vehicle was safe to drive and they told me they cannot legally tell me if it is safe or not. There is no way forward to fix my vehicle and I haven't received any information other than "we are waiting on parts". With this being a safety issue, I would expect a loaner vehicle of a similar make and model. I do not feel it is safe to continue to drive my truck with these warning lights associated with an active safety recall. I am looking for advice or some help with this issue.

Antilock braking system and stability control. Can’t use cruise conteol

Abs hydraulic control unit defective dealer and manufacturer have failed to produce replacement parts it’s been over 2 years

•Side curtain airbag malfunction front driver's side. The truck has a warning light for the airbag and the computer diagnostics says it is a side airbag malfunction. The vehicle is well kept and has not been damaged. Mopar does not lost this malfunction and recall as included in my VIN •Cruise control malfunction The cruise control sporadically does not turn on when the button is pressed. The button may need to be pressed a dozen times before it activates and cruise control is available to be set for a given speed and then engaged. This has occurred since purchase brand new at the original dealership at less than 25 miles on odometer. Mopar does not list this malfunction/recall for my VIN. •Hydraulic Control Unit recall difficulties. The dealership has stated multiple times it has no replacement parts to do the recall repair covered under NHTSA Recall # 24V-896.

While operating my 2018 Ram 2500, the Hydraulic Control Unit (HCU) failed suddenly and completely, causing the loss of: Anti-lock Braking System (ABS) Electronic Stability Control (ESC) Traction Control This failure occurred without warning, creating an immediate risk of accident.

I received notification of a recall in November,2025. However, Ram has still not come up with a resolution. This is almost a year without ABS on my truck. The Traction Control, ABS, and parking brake lights are all illuminated and the cruise control does not work. My wife refuses to drive my truck without ABS, traction control, and cruise control.

While operating my 2018 Ram 2500, the Hydraulic Control Unit (HCU) failed suddenly and completely, causing the loss of: Anti-lock Braking System (ABS) Electronic Stability Control (ESC) Traction Control This failure occurred without warning, creating an immediate risk of accident. The dashboard illuminated warning lights indicating system failure. The most recent diagnostic, performed on 8/19/2025 at Haley Chrysler Dodge Jeep Ram, confirmed that the HCU requires replacement. Previous incidents with the vehicle involved intermittent failures of the same systems, indicating a persistent and unresolved safety defect. The dealer has indicated that a permanent fix may not be available until late March 2026. Due to the ongoing safety risk and extended timeline for repair, I am requesting a manufacturer buyback at this time. Stellantis has not provided rental coverage upfront, requiring that I pay for a rental vehicle and submit reimbursement, which imposes financial hardship while the vehicle remains unsafe.

Abs module has been on recall for a while with no parts available to fix issue. I would like to know what are the options available?

Manufacturer Recall Number C4B; NHTSA Recall Number 24V-896 Recall Status Incomplete, remedy not yet available This problem is over 2 years old and still incomplete; why is there no time limit for them to fix; they are pumping out new sales and new problems but nobody is accountable. Still warning light every time driven and nobody can tell us when it will be fixed...

unknown my brakes had a recall on it for the hydraulic system my transmission gave signs of going out while i was driving it would rev up and then would go when i would increase speeds

I have had this truck since 2018, I have had to repair the brakes , break pads and lines 6 times now and one time almost causing a horrible crash in Oregon slamming into a guardrail. I am tired of hearing there’s no way they can fix it, they have no parts to fix it , they don’t have parts to fix it, it’s a sever safety concern, why am I constantly having to repair these brakes and no one can help other than an attorney.

My HCU has failed and now I don't have anti-lock braking, electronic stability control, traction control, or cruise control. I have contacted Mopar and two Ram dealers in my area but they just tell me there is no remedy. This has been going on since December of 2024.

RECIEVED A RECALL NOTICE (WILL TRY TO ATTACH TO THIS COMPLAINT) on or about December 2024 (ACCORDING TO RAM REPRESENTATIVE) stating that '[T]he BRAKE hydraulic Control Unit (HCU) ON YOUR VEHICLE may be susceptible to failure... The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning.' I called several Dodge Ram Dealers to have the recall fixed on or about December 2024 & was told that there was no fix yet available. Called again a couple of months later and was told the same. After that I forgot to followup again until today 8-11-2025 and was again told the same. IT HAS BEEN ABOUT 9 MONTHS & EVEN THE NHTSA NOTICE ON YOUR WEBSITE SAYS THAT RAM STILL HAS NO SOLUTION TO THE PROBLEM EVEN THOUG THE RECALL NOTICE MAKES IT CLEAR THAT THE PROBELM IS AN "IMPORTANT SAFETY ISSUE. " I REQUEST THAT THE NHTSA CONTACT DODGE RAM AND FORCE THEM TO COME UP WITH A SOLUTION TO FIX THE RECALL ASAP. because of the admitted safety issues. -

Manufacture has not provided a fix in a timely manner for safety recall

I received a recall notice for my 2018 Ram 2500 in November of 2024. It's now August of 2025 and the manufacturer still has not provided a remedy for the recall. I am unable to drive the vehicle because of this recall. I am getting warning lights and tones associated with the brake system. How long will a solution to the recall take? It's already been 9 months!

KEEPS FLASHING ABS. IT SOUNDS A BING NOISE THE WHOLE TIME I DRIVE IT. SINCE I DRIVE OVER 2 HOURS A DAY IT IS REALLY FRUSTRATING AND 5 HOURS ON THE WEEKEND. ALSO, THE RADIO CUTS OUT ALL THE TIME WHEN THE ABS IN FLASHING THE AIR CONDITIONING OR HEAT GOES FULL BLAST WHEN THE ABS IN FLASHING AND BINGING. HOW CAN YOU NOT HAVE A FIX FOR THIS YET!

Recall 24V-896 does not seem to being worked. Is there any update on if and when this recall will be fixed.

In early December my 2018 ram 2500 was giving error messages to service anti-lock braked and service Electronic brake system. On December 19, 2018 I took the Ram to the dealer and the cause was the HCU-ICU stating internal electrical failure. They installed a new (Control unit HCU - brake- anti-lock module. It was fine until October 2024 when the same errors (service Anti- lock brakes / Service electronic brake system.) I received a RE-Call notice about the same module (HCU) having issues in November of 2024. I have called the dealership and they have not received a remedy (parts) to fix the issue. The error messages keep coming on Saying service anti-lock brakes- service electronic brake system. Its July 31, 2025 and Still no remedy from the dealership. I signed up on the RAM / Chrysler / Mopar website to be notified when a remedy is parts are ready however I believe it's been too long to wait and appears Im not the only consumer waiting on one. is there any way to remedy quicker I pull a travel trailer and don't want any failures although the dealer said the truck is ok to drive,

Truck dashboard is going crazy lighting up that their is issues with the brakes coming on and off, scared to even drive these truck because who knows when and if brakes will fail. This is a lawsuit just waiting to happen.

If I hit a bump it sets off the lights for the abs and the traction control and I have to run my truck with the traction control off if not my truck won’t shift right if I’m going 60 or above also had to get the transmission replaced

The recall has been out for months and Ram still has no solution, yet parts are available if you purchase them. I paid for replacement for the same ABS issue 3 years ago before it became a recall and now the part has failed again.

Manufacturer not providing corrections for brake hydraulic control

In December 2024, I received recall notice C4B for my 2018 RAM 2500 truck. The notice concerned the brake hydraulic unit, which is susceptible to failure. At almost exactly the same time, I started to receive dashboard indicators to check the ABS, but it worked fine, I just assumed that the alert was related to the recall. The recall stated that parts were not available and that I would be contacted when there was a resolution. The notice did not indicate that the vehicle was unsafe to drive. Around [XXX], the brakes began making a grinding sound from both sides of the front wheels. I checked the pads, which seemed fine, and there was no scoring on either front rotor. Coincidentally, I got a flat on the left front tire the day after the grinding noise started. It was in the driveway and I was unable to put on the spare until July 12, 2025, the vehicle sat in the driveway with a flat tire until then. After swapping in the spare on the 12th, I planned to get the tire repaired at my local garage. I began pulling out of my driveway at a few miles per hour. I applied the brakes to maintain a slow speed, and the grinding worsened. As I reached the end of my 30 foot driveway and pulled into the street, I heard a clunk, which I also felt through the brake pedal. The pedal immediately went to the floor, and the vehicle rolled across the street before finally stopping. I was able to back into the driveway and park the vehicle without incident. I contacted my local RAM dealer, and they said there was nothing they could do. They gave me the number for Fiat Chrysler Customer Care. I called Fiat Chrysler Customer Care at 800-853-1403 and received case number[XXX]. They explained that a resolution was not yet available and advised me to call a dealer and ask for a "temporary fix". When I told them the dealer had already said they couldn’t do anything, and that the dealer told me to call them, they suggested that I try a different dealer.

I have repeatedly asked the manufacturer and the dealership for a resolution to the antilock brake system failure on this vehicle. This issue has been on going for months and I have no resolution. This is Ram case management # 93024671. My last correspondence is as follows: Dear Stellantis Case Management Team, I am writing to express my profound dissatisfaction and serious safety concerns regarding my vehicle, 2018 RAM 2500. This letter follows a delayed response to my initial inquiry about the safety of my vehicle and family, which I find unacceptable. Firstly, I request an immediate and definitive anticipated release date for the crucial part that is pending. The continued uncertainty around this essential component is directly impacting my peace of mind and the perceived safety of my vehicle, my family and the general public. Secondly, I demand a thorough explanation regarding the active fault code on a manufacturer safety device within my vehicle, which your company has inexplicably deemed "normal" and stated the truck is "able to be driven." This assessment is illogical and deeply concerning. If a safety device, such as the anti-lock braking system (ABS) or a similar critical component, registers a fault code, its integrity and intended function are compromised. My fundamental question remains unanswered: If a safety system with a fault code is considered "normal" and safe, then why are such sophisticated safety features like anti-lock brakes installed in the first place? If their compromised state is acceptable, why not simply remove the entire system? This reasoning fundamentally contradicts the purpose of vehicle safety design and creates an unacceptable risk for myself and my family. I gave them 7 business days to respond- there has been no movement.

Brakes went out abs/traction control/tpms lights on. Brake pedal goes to floor 50% of the time. Have to downshift and use engine brake to stop.

Vehicle is subject to safety recall for malfunctioning HCU. Frequent illumination of Anti-Lock Break and Traction Control Warning Lights with accompanying Chime and loss of Cruise Control function. When illuminated, vehicle rear wheels will slip and braking is degraded. Illumination of Warning Lights and chime very distracting. FCA initially estimated repair parts available first quarter of 2025. This has passed and no updates are available from manufacturer. This is an unsafe condition.and I request NHTSA intercede on behalf of the 300,000+ owners affected and seek clarification from manufacturer on when they plan on honoring this recall.

ABS HCU recall.

Logging a second complaint for the brake hydraulic control unit that is already recognized by FCA as a defect that needs to be replaced. I am two years into this failed unit and continue to be told by the dealer and manufacturer's customer service that the replacement part is not available and they do not have a delivery date for this part. In the last two years I have had (4) near collisions as a result of no anti-lock brakes and no traction control. Additionally the cruise control is not active when this part fails and as a long-distance driver this is fatiguing. The contant dinging of the warning light and bell is extremely irritating. The reference number for FCA's recall is C4B/NHTSA 24V-896.

The manufacturer has not designed the replacement parts in a timely manner. 7 months since initial recall and still no parts available.

Towing my camper with my family in the mountains during Memorial Day weekend. It was rainy. My brakes failed me SEVERAL times as well as my traction control. To say it was scary is an understatement. I don’t even want to use the truck anymore. I have had several chats with ramcare as well as a call to my dealership with zero resolutions. Someone is going to get hurt or worse. The HCU no longer works.

The warning lights that I have a braking system malfunction continuously "bing" and display on the drivers console. This has been going on for approximately 1 year and Fiat Chrysler of America does not have a solution to this date. Here is the recall information: - Manufacturer Recall NumberC4B -NHTSA Recall Number24V-896 -Recall StatusRecall Incomplete, remedy not yet available I reported this to the dealer approximately a year ago and have since taken to the dealer for service where they told me once again there is no fix for this problem. I have called FCA as well but they are unable to provide any additional information.

ABS keeps going off. Ram setup to appointments to fix issue but after going to dealership and sitting for two hours they say they don’t have parts to fix

Recalled for HCU 11/2024. Still no remedy/fix available.

Leaking brake fluid, brakes grabbing and brake paddle is soft( no pressure).

Ram issued a recall (NHTSA Recall Number 24V-896) on November 27, 2024, and there has been no remedy for repairing or replacing the faulty Brake HCU. It has been six months with no remedy in place for this recall. How long should it take to fix the known problem with this vehicle?

Manufacturer has failed to remedy ABS HCU recall for over 6 months. Vehicle is beginning to exhibit ABS warnings. This wait for parts is unacceptable, especially for a braking system recall. Please get the manufacturer to deal with this issue in a timely manner.

Manufacturer has failed to have a solution to current recall, 24V-896. It has been at least 6 months with no resolution.

ABS warning light and alarm come on while driving. If you have cruise control on, it then cancels the cruise control. After a few miles the warning light and alarm will go off, and works good for a few miles. Then the same thing happens - warning light and alarm come on again. This has been an ongoing problem, over a year. Went to dealer where purchased vehicle. Was told that Chrysler doesn't have a fix for this and doesn't have parts to fix it either. So there is nothing I can do. No parts to fix, dealer can't help, and meanwhile I have a faulty vehicle which is my main vehicle I drive. The ABS system is real handy here in Minnesota because of slippery roads in the winter with snow and ice.

There is a well know issue with potential failures in the Hydraulic Control Unit (HCU), which can impact critical braking and stability systems, including ABS, Electronic Stability Control (ESC), and traction control. Manufacturer Recall # - C4B NHTSA Recall # - 24V-896 There has been a recall on this issue since Nov of 2024 however, there has been no remedy offered yet on most models affected. I am experiencing this failure on my 2018 RAM 2500. It is noted in the recall that this failure is a safety issue and can cause the car to crash without prior warning. The remedy is know by RAM as they have issued it for certain chasis types. The Brake HCU must be replaced. I believe RAM's delay for a remedy is simply the cost and they are willfully putting lives in danger over financial impacts.

The Electronic breaking system, Antilock Brake System and traction control on my 2018 Ram 2500 failed in June 2024. My safety has been put at risk because my ABS does not work properly and neither does my electronic traction control which is unsafe for myself and others on the road. It has been inspected by the manufacturer but I was parts are not available for the repair. Yes, I have had the warning lights since June 2024.

Why, after more than 5 months of a recall issuance, is there still not a "fix" issued to service dealers to make needed replacement of the Hydraulic Control Unit ABS (recall C4B)? Is anybody overseeing this matter to ensure timely resolve to this safety issue? I called my local Dodge dealer this morning to check on this after not hearing any further word about it despite registering my vehicle for recall notification with Fiat Chrysler Automobiles, and learned that they have a bulk shipment of 16 HCU units in stock, but they do not have the vehicle computer programming (or something to that effect) to initiate fixing the matter. I sure hope the HCU on my truck doesn't fail and cause an accident.

Mopar part numbers 68143491AA Control-Anti-lock brake system and Mopar part number 68347098AB Module-Anti_lock brake system both failed and were replaced/repaired by dealer under warrranty where I purchased the truck. Truck had 8,223 miles on it. Brakes and traction control was compromised. Numerous warning lights and warning tones were observed.

Under the Recall information it shows that this vehicle is unsafe to drive due to the ABS system in Major. It will go off and go on all by itself while I’m driving. and they can’t get the part I need.

WE PAID ABOUT $70,000 FOR OUR 2500 RAM TRUCK. AS WE WERE DRIVING THE FREEWAY OUR ABS WARNING WENT OFF SHUTTING THE CRUISE CONTROL…THIS GOT TO WHERE IT HAPPENED QUITE OFTEN.. AT THE TIME THERE WERE NO RECALLS ON IT SO WE PAID A TOTAL OF $2,030. WE HAD ADDED A FUEL FILTER CHANGE WHILE WE HAD THE VEHICLE THERE. ONCE WE RECEIVED THE RECALL LETTER WE FILED FOR A REFUND. I RECEIVED AN EMAIL STATING THAT THEY WOULD ONLY REFUND $1656.00 . WHEN I WROTE BACK..’’ MAY I ASK WHY I AM NOT GETTING A FULL REFUND?’’ I RECEIVED A VERY RUDE EMAIL THAT THE PAYMENT WAS FINAL WITH NO OTHER EXPLANATION!! I CALLED TWICE TRYING TO GET THIS RESOLVED TO NO PREVAIL. I TOLD THEM THAT I DID NOT EXPECT THEM TO PAY FOR THE FUEL FILTER BUT THAT STILL LEFT $250. BECAUSE OF MY HUSBAND BEING A DISABLED VETERAN WE RECEIVED A DISCOUNT AND PAID NO TAXES WHICH SAVED FCA MONEY!!! I WANT THE $250 THAT IS OWED TO US.

Stellantis has failed to remedy this recall dating back to NOV 2024.

ABS INTERMITTENTLY ALARMS VERY FREQUENTLY AND CAUSES THE CRUISE CONTROL TO DROP OUT. I ASSUME THE ABS IS USELESS AND THIS TAKING PLACE. I’M TOLD THIS IS A COMMON PROBLEM.

In November 2024 through December 2025 our Ram started experiencing issues with the traction control and ABS lights coming on randomly and the vehicle not braking properly. Braking in corners is very sketchy and feels like you are going to run off the road. As December went on, all brake related lights stayed on and the truck feels like it has manual brakes from the 1970s. We received a Legal Notice explaining there is a class action settlement going on due to the ABS module and Brake HCU on our truck in late December 2024. We did not drive the truck long distances for the latter half of December due to the issues we were experiencing plus receiving the legal notice. A couple weeks into January 2025 we received a notice from FCA US LLC indicating there is a safety recall for the Brake HCU which affects the ABS and ESC systems. The notice said the vehicle may lose control and cause a crash without prior warning. Due to this second notice and the fact that our truck was having more issues with the braking systems and the lights were permanently on, we parked the truck mid January 2025 and have not driven it since. In early March we contacted the local dealership Morie's of Little Fall, MN as well as Chrylser/Mopar asking when our truck can be repaired and explained this is our daily driver and only safe vehicle we have for distances over 30 miles. Neither of them have been helpful and could not give us an answer. The service person at Morie's confirmed our vehicle is a part of the recall and the things we are experiencing would be related. He advised we do not drive the vehicle either. We are now mid April, THREE MONTHS WITHOUT A SAFE VEHICLE TO DRIVE, and we have received no further communication from anyone relating to our truck. It is still parked and unsafe to drive. Action needs to be taken to remedy this situation. We are normally a two vehicle household down to one that can't be driven far and one that can't be driven at all.

ABS light comes on and off during operation, "service electronic brake system" notification flashes on and off as well. ABS does not work while light is on. A scanner has been run and the code is for the ABS module. We put children in this vehicle. This exact issue happened back in 2022 and the ABS HCU was replaced. We received a recall notice but are being told the truck has been repaired because the part was replaced in 2022, however the same issue is currently happening again.

Dodge/Chrysler/Ram has known about this issue for a long time. I experienced the conditions outlined in the recall on my personal vehicle, before there was a recall issued. I took it to my local dealership to have the issue repaired in August 2024. They said the brake sensor is in national back order and could take a year to get the part in. How can you issue a safety recall but not have the parts available to fix the truck?

HCU has failed on my truck back in July of 2024 it was impossible to find a replacement part got a recall letter on November had abs track control, and cruise control loss repeated dinging sounds to service ABS and electronic brakes and most recently you can hear the brake pads slightly rubbing on rotors and can feel a little bit of resistance while driving down the road

On August 10, 2022 the truck was presented to the dealership because the ABS system was failing. This was prior to the recall C4B/NHTSA 24V-896. I paid to have the system repaired. A recall was issued AFTER that date. I submitted a claim and was paid for my expenses by FCA. On March 3, 2025 the system notification system flashed warning the the ABS system was failing. I immediately took the truck to Mac Haik dealership and was advised that I could safely drive the truck until the following Monday when I could drop it off for diagnostic testing. The diagnostic testing revealed that the system was failing BUT FCA would not cover the full cost of the repairs. They would require "Customer Participation" payment of $546.00. I refused the repair because the repairs done August 2022, PRIOR to the recall was failing, so that told me that the parts utilized August 2022 were faulty and should be replaced under the terms of the recall and not require "Customer Participation of $546. I need your help to get FCA to replace and repair their faulty manufacturing.

It's been 2 months and there's no fix. Ill happily accept a repair but I want a refund or another vehicle if they can't fix it. I have no ABS or electronic braking system. I've been unable to drive it for years. The part needed is unavailable and dealerships tell me it will be a software update when a fix becomes available when the recall notice says new part. I just want to be able to drive the truck I pay almost 700 a month for. Thank you!

Hello, I received my recall notice cb4 hcu component and in my notice it said my truck has already been fixed.

I have been working via my recall letter. They have provided me with approval for a rental car, but so far I have been getting mixed information on the reimbursement and have not been reimbursed. They have not and will not provide me a date for repair. I use this truck for specific activities, and rental car options are not equivalent, and again I have not yet been reimbursed. I am reading my rights and resubmitting a complaint that the manufacturer has not remedied this situation. I need 100% reimbursement for my rental car, including taxes and non-optional fees, and my truck repaired, or purchased back. I will continue researching the legislation Photos showing my truck has this defect are attached. I need to have an equivalent, safe vehicle to use, or have money from this one to buy one that is.

My recall says that it has been repaired on December 5 2024. My truck has not been repaired I took it to the dealership on December 5th and they said they could not do anything until the recall came out. So now they will not fix the hcu cause it says it has been repaired. I have to drive a truck with no ABS cause someone made a mistake.

I have contacted multiple dealership’s and have been told that a recall about the ABS HCU module was “completed” yet, Every dealership is unable to provide a place, mechanic or even a work order proving said repairs were completed. My ESC traction control light, Service Anti-lock Braking System, Service Electronic Braking System, and Service 4WD lights are now on. And I cannot get the issue repaired because of a mistake within the system. Joe Cooper Dodge in Shawnee, Oklahoma would not diagnose the vehicle due to the issue mistakenly being marked as “Completed”. Even after making a face to face appearance with vehicle present.

Approximately January 2022, several warning lights illuminated on my dash in conjuction with a warning chime. The warning lights and chime occurred intermittently. My truck was taken to the dealership with only 9710 miles on the odometer. A scan showed a code of C0020-01 ABS pump motor control general electrical failure. Approximately 5 months later a new part arrived and was installed on the truck. There were no issues until February 2025 when the dash warning lights and chime reappeard similar to the first occurrence. The odometer reading now at 16.5K. I have contacted the dealership that performed the original work and they informed me that there is currently no repair for this issue. Having no ABS braking system is a major safety issue, especially when pulling a large travel trailer.

My ABS light keeps coming on intermittently. I been calling mopar since this recall started in 2024 and they are not supplying needed parts to the dealership to fix it. I call mopar and no ETA on the parts. I want this fixed since they said it can cause my truck to wreck with no notice. I have kids in my truck all the time and mad on delay. How are they getting by not fixing this.

ELECTRICAL BRAKE FAILURE WARNING

I have received an "Important Safety Recall" issued for my vehicle. In the notice, it states that "The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning." I have contacted the dealership as well as RAM offices with no answer other than that the part is not available. As a safety issue, this is unacceptable. Please know that legal representation will be sought out.

The ABS brake warning lights are on all the time. I have no cruise control. There are times when I can't even shift my vehicle into gear. I will be checking to see if I even have 4wd with this light on. But, haven't tried it since the lights have been on.

August of 2023 I had my service electronic braking system, abs, and traction control light come on. Dealer diagnosed as bad hcu. As of today 2-4-25 I am still waiting on parts with no answer as to when parts will be available for the repair.

The recall was issued for the Hydraulic control unit but there are no parts available to fix the issue..this in my issue. They have no HCU unit for over a year now. I contacted the dealer Deacons Chrysler in Ohio. Dealer wants me to pay for the diagnostic for the recall. But there is no parts available. This is unfair. How long do we have to wait for parts. And why do I have to pay for the recall diagnostic?

This in regards to existing recall C4B or 24V-896. Recal has been active since November, but parts are still not available to fix this problem. FCA is not taking this safety risk seriously.

I am filing this complaint due to a GREAT safety concern with my vehicle. I am a law enforcement officer as well as a firefighter. I was notified that there was a safety recall on my vehicle. The recall was for the hydraulic control unit ("HCU"). One of the risks of said recall is the loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning. After being notified about said recall, I notified several Ram Service locations in my area as well as the surrounding areas of where I reside. Each and every one of the service personnel or advisors I spoke with told me “there is not a remedy for the recall as of yet due to parts not being available.” When asked what I needed to do at that point, I was told to continue to drive my vehicle. Each dealership I spoke with stated they did not offer loaner vehicles, and did not know when parts would be available to fix said recall. That brings me to my complaint. On the morning of January 21, 2025 at approximately 05:47, I was driving my daughter to school then I was going to go to work there after. When I left my residence, I approached a stop sign to make a right turn. When I made the right turn, my front driver’s side wheel, locked up and pulled the vehicle hard to the left causing me to nearly strike a sheriff patrol officer and crash into a nearby residence. My daughter and I are severely shaken by this incident, and it could have been tremendously worse than it was. The Ram service departments should not be encouraging anyone to continue driving the vehicle models with this recall. It nearly killed my daughter and I. We have never experienced anything like this. This vehicle is not, and it has not been safe for operations for my family. Due to this incident I no longer have a drivable vehicle, and I still have to make the payments on said vehicle. I have looked into this problem and have found out there are two class action lawsuits in different states due to this problem. This is not a new issue.

I'VE BEEN OPERATING MY TRUCK SEVERAL TIMES NOW WHERE THE CRUISE CONTROL HAS WENT OFF OR DISENGAGED WHILE DRIVING, CAUSING A SLIGHT PANIC FROM NOT KNOWING WHAT WAS GOING ON IN THAT MOMENT. THIS HAS ALSO HAPPENED WHILE TOWING, WHICH MADE THINGS EVEN WORSE. MY CRUISE CONTROL IS NO LONGER WORKING AND NOW I AM DEALING WITH THE RECALL WHERE THERE IS A "REMEDY NOT YET AVAILABLE". THIS WOULD BE RECALL MANUFACTURER NUMBER C4B AND NHTSA RECALL NUMBER 24V-896. I BELIEVE THIS RECALL TO BE TIED IN WITH MY CRUISE CONTROL ISSUE. NOW I HAVE A TRUCK THAT I HAVE NO OTHER OPTION THAN TO OPERATE AS MY DAILY DRIVER; WITH NO CRUISE CONTROL, ABS/ECS/TRACTION CONRTOL. I'VE CONTACTED SEVERAL DEALERS TO SEE IF THEY HAD ANY INSIGHT AND I HAVE BEEN GIVEN THE SAME ANSWER ABOUT THERE NOT BEING A 'REMEDY'. I WANT IT TO BE KNOWN FOR LEGAL PURPOSES THAT I DO NOT FEEL SAFE OPERATING MY TRUCK AT THIS TIME BUT AGAIN I HAVE NO OTHER VEHICLE AT THIS TIME TO OPERATE. I HAVE AGAIN REQUESTED ASSISTANCE FROM SEVERAL DEALERS WHO HAV BEEN UNABLE TO HELP ME WITH THE RECALL LISTED ABOVE.

The Anti-Brake system ABS and ESC Electronic Stability Control alert keeps coming on and off on my dashboard. The cruise control will shut off by itself when this alert comes on. The alerts appear randomly and all various speeds. I took this to the dealership in October of 2022 for this issue and they replaced the anti-lock brake controller and bled the brakes. I had to pay $1000 out of pocket cost as my truck was no longer under warranty. The same issue has started occurring again in June of 2024. I changed out the wheel speed sensors at that time thinking perhaps that was causing the issue since I got the repair done in 2022 and I noticed that the issue occurs frequently, especially when I hit a bump in the road. However the issue still occurs and I see that this has been a known issue by Ram for some time and a RECALL for the HYDRAULIC CONTROL UNIT is due to be mailed out January 9, 2025.

WHILE OPERATING VEHICLE THE ABS AND TRACTION CONTROL LIGHTS WOULD FLASH ON AND OFF AND MESSAGE SERVICE ANTI LOCK BRAKE SYSTEM. THEN SERVICE ELECTRIC BRAKE SYSTEM WOULD FLASH AND BEEP IN MESSAGE CENTER. AFTER FLASHING ON AND OFF MULTIPLE TIMES THE MESSAGES SELF CLEARED AND LIGHTS WENT OUT. DURING THIS IT IS HARD TO CONTROL THE TRUCK. CRUISE CONTROL NOT WORKIING EITHER.

Hydraulic brake unit failure. yes part is still available for inspection as it is still n the vehicle. I was driving to work at 21:30 hours on 1/1/2025 on a snow covered road. I gently applied the brakes and my truck went into a spin. I was going 25 mph. the abs unit failed and there was no pulsating in the brake pedal and rear brakes locked up sending the truck into an uncontrollable spin. my front left driver side of the vehicle then struck the jersey barrier and vehicle did continue to spin and then struck passenger rear side of the vehicle on the jersey barrier. currently has $17k in damages to the vehicle. I was not injured at the time but currently experiencing lower back pain. there was no lights or warnings on dash until immediately after the collision. I had the ABS HBU replaced a few months back and was told the new unit was part of the old stock and would most likely fail. which it did. unfortunately i am one of the people in this world who could not afford to not drive my vehicle as the truck was $70k new and i still am currently driving it due to not being able to afford to replace it of park it and rent a vehicle. The HBU has been a known issue in these trucks for the passed year and they just issued a recall on 12/08/2024. this problem was first noticed on 05/08/2024. was taken to dealer shortly afterward and was told that these are known to fail and currently no remedy to the issue. as of 01/07/2025 there is still no remedy or time on when parts are available for replacement.

Hello, I hope I not wasting your time, Well, no accident has occurred, because the vehicle is not driven much, because The manual says not to drive it like that, and does not even have 6,000 miles, the year is 2018, the problem is the (abs) anti-lock brake system, the vehicle was checked by the dealer on 12/06/2022, and there is still no answer,

whilst driving, the ABS/traction control warning lights will randomly come on, then go off, and come on again. Sometimes they stay off, other times it is constant dingining as the lights appear and disappear, then re appear. when they are on the traction Control, and ABS do not work. I feel the truck is unsafe in incliment weather, or panic sitiuations that require emergency braking, or slick conditions where Traction and stabili track is important.

My abs control warning goes on and off and will not allow me to use cruise control and is constantly beeping at me.

I am continuing to have warning lights telling me to service Anti Lock brake system and also the Electronic brake system. I took it to a dealership and they told me that the hydraulic control unit and the ABS module was faulty but made no attempt to resolve the problem unless I paid over $6000 for the repairs. My truck only has 122300 miles on it and it has been a constant problem. i don't have the money to pay that and it's my only vehicle.

HCU unit intermittently come On and off. Has the potential for loss of traction control and braking.

I received notice of a safety recall concerning the brake/ anti-skid control module. This notice said there was a possibility of complete failure that could result in serious injury or death. I contacted my local dealer and was told the recall wouldn't start until the first quarter of 2025. I told them my dash warning lights were already on. Their advice was to park my vehicle and obtain other transportation because of the danger. This seems to be unreasonable to me. It would cost a lot to rent another truck for that period of time. This seems to be putting my family and me in danger! Is there anyway to proceed earlier?

Warning lights and loss of ABS braking, and traction control. The computer has been replaced before and the same issue has happened again. I noticed a recall for the same issue and same model year, but was told my vehicle is not covered by this recall. The warning comes and goes very frequently and I am never sure if the ABS will work. This vehicle is used to tow trailers and the lack of ABS brakes is a safety problem.

I bought this 2018 RAM 2500 in February 2024 from a certified dealer. They indicated the ABS light was on however I was traveling out of town and they indicated my local dealer could fix this faster and lowered the price by the estimated cost for repair. I have been working with my local Mechanic for almost a year to solve the ABS modular problem but the local RAM dealership states the part is on back order or nonexistent. I have driven the vehicle very little due to the worry of an accident after not being able to resolve this issue. When driving the vehicle, the ABS light is on and constantly sounding a warning. Again, I have not been been driving this vehicle due to the dangerous situation it may cause. In my opinion, the dealership should have never sold me this vehicle, knowing that repair parts are unavailable for the ABS module. I was never informed of any recall on this vehicle at the time of purchase or since the purchase.

Abs traction control and cruise not working due to ABS MODULE FAILURE FOR S THIRD TIME

ABS warning system light constantly pops on and off.

My ABS master unit/Traction Control unit has been replaced once. Now it needs replacing again. The currently installed ABS/Traction Control unit is available for inspection. The problem has been confirmed by a dealer service center. They are the ones that replaced the first unit. The vehicle/component has been inspected by the dealership. Warning lamps (ABS/Traction Control) come on and off intermittently while the vehicle is in use. It also comes on and off while the vehicle is idling in park.

At Roughly 38000 miles the ABS and Traction control light began going on and off intermittently. Took to local dealer and the replaced the ABS HCU and Module to the tune of $1000. Now 2 years later and 54000 miles and it has failed again doing the same thing. This is a well-known issue for the 2017 & 2018 RAM 2500 pickups like mine. This is a serious safety issue which needs to be addressed and fixed by RAM.

My trucks braking systems hydraulic control unit (HCU) is Malfunctioning. It goes in and out of service while driving and two warning lights and a buzzer will sound on and off. This part was replaced during the 3/36 warranty and again when out of warranty for two replacements before 71k miles. Now for the third time it’s malfunctioning at 111k miles. I failed to convince Ram to replace it for the third time under warranty and was denied. I was told the part and the truck is out of warranty and will be an out of pocket expense to repair. I feel the dealer installed a known faulty part and Ram should replace it with the new corrected part number at no cost.

ABS and Traction Control lights come on intermitenetly and loss of cruise control. Says service ABS Control System. This is a very common issue and something that could easily cause a major accident in not ideal situations if not resolved quickly. The dealership has inspected it and confirmed the ABS Module is the culprit. This is obviously something that is common and should be investigated more.

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE continues to come up in my vehicle each time a bump in the road is hit. I am very concerned that this will cause intermittent or permanent loss of braking performance while driving and potentially endangering myself and other motorists. There are numerous complaints about this same issue on the internet with these model year trucks and FCA should be doing something about this inherent risk.

ABS warning keeps flashing intermittently. The HCU module apparently has issues. Took vehicle back for another recall issue and they told me to watch it and if I pulled trailers to bring it in. Apparently, dealers are aware this is an issue and research showed me that a recall Is possible so I am reporting the issue.

Anti-lock brake hydraulic controller failure

ABS and traction lights going off and on daily. Dealership has no parts and unable to fix problems

The abs and electrical brake system lights stay on. I’m worried that this will affect the functioning of the brake system. I’ve read many posts on forums about this happening to other people. It sounds like a manufacturer defect. I have not brought it to the dealer yet because the cost of repair sounds like a lot of money.

ABS control module is out, code c0020-01 I know 3 other people with the same issue. It is a widespread problem with these rams. Especially in the 2017-2018 years. How can there be a widespread issue like this and there not be a safety recall, seems like an issue with the brake system would be recalled quickly.

ABS System. It is available for inspection. On my 2018 Ram 2500 HD 6.7 Cummins Big Horn the ABS warning lights start flashing and warning alarm will start beeping. This is intermittent, but lately much more constant. The big safety issue is when I'm trailering and the ABS system flashes I lose my trailer braking ability. Also, if I'm on cruise control and the warning light comes on, it drops out of cruise control.

intermittent warning light and messages about the electronic braking system and the ABS. Without failure at this time

My vehicle has had the Service Electronic Braking System/Service Antilock Braking System warnings appearing for approximately 6 months, along with the ABS light and Traction Control light being illuminated. It was intermittent at first but has been on steady for the past month. The vehicle has not been to the manufacturer to get inspected yet due to the intermittent nature at first. With the lights being illuminated, I have had a time or two where when the brakes were applied in a quick manner, the abs was not engaged and the tire locked up when a deer ran across the road.

often experience noticeable braking issues. illumination of the ABS or brake warning light on the dashboard, indicating a problem with the anti-lock braking system. difficulty maintaining proper braking pressure, especially in emergency braking situations or on slippery surfaces, where the ABS should engage. As a result, the vehicle's stopping distance increases, and I have noticed a lack of control during hard braking. In some cases, the brakes feel soft or spongy due to improper hydraulic pressure regulation. Additionally, intermittent or complete loss of ABS functionality has occurred, leading to less stable braking performance.

Have had my truck into the dealer several times to check a hard brake pedal. No error code. When stopping it feels like there is no power brake Assist.

This is 3rd time I have had ABS failed. Truck only has 66,000 miles on it and this has happened for 3rd time. Has been twice repaired by Ram dealer in Denham Springs Louisiana. Evidently parts are defective. I am original owner. First time happened at 24,700 miles. Second time at 48,200 miles. Third time at 66,000 miles. Evidently bad parts.

The Anti-Lock Braking System (ABS) Traction Control warning light and warning bell comes on after hitting bump in road or just randomly. Anti-lock brakes no longer work and it is a safety hazard. this issue back at about 78,000 miles. This is an ongoing safety problem with Ram 2500's and there is no recall by the manufacturer for a known defective part.

ABS module causes abs light to periodically come on and shut off from time to time.

First abs control module was replaced at 27k miles, now the second abs control module has failed again and needs replaced at 49k miles. There are many of these truck that these modules have failed on and the abs will not work.

ABS warning lights keep flashing in my truck, dodge has no fix for this problem, all they say is parts are in redesign and unable. what can be done here?

ABS brakes

The ABS and traction control light flash and sound repeatedly. As well as loss of trailer brake control. This is the second time the vehicle has done this. The first time I fixed it as Fam said it wasn’t covered by the warranty. I replaced the ABS module and HCU on my own dime. This is a major safety concern and should be treated as such.

“Service ABS” and “Service Electric Brake System” cautions alerts accompanied by warning chime, traction control and cruise control failures. Known issue with the Hydraulic Control Unit on this model. Dealer couldn't get parts as they were back ordered and now when available the price has tripled. Replacement parts seem to have the same issue. This started with about 25,000 miles on the vehicle.

ABS and traction control module defect. Dealer says repair not a recall.

Abs/hcu on the braking system has failed twice in the 3 years I've owned this truck.

Timely as my 2018 2500 seems affected. I've performed no troubleshooting but it is extremely intermittent, either the Service the ABS or Service the Electronic Braking System(s). Usually, a bump in the road makes it come and another turns it off. Sometimes it happens so quickly, only the message and traction control disabled light comes on, sometimes only the chime comes in. Sometimes the message stays up and the brake warning and traction control light comes on, sometimes for a few minutes, sometimes a couple of seconds. Always goes away with an ignition cycle. If it's on long enough. For some period of time, it came in when I turned the truck on and off when I released the parking brake. Annoying.

Failure of abs / hec control module of abs /traction control system ...part has been on order for over 2 plus years only 15 k miles and failed .This would result in accident of abs not working properly .

Failure of traction control and ABS system. Causes loss of control in wet and snowy weather. Receiving C0020-01 ABS Pump Motor Control General Electrical failure code.

The abs module has gave me issues and now has gone completely out causing no brakes and while it was having intermittent issues causes no cruise control and causes transmission issues which is another thing the transmission has went out again after this is the 3rd time replacing at around 10k everytime

The ABS and Traction control system which is operated through the ABS Module intermittently goes on and off alerting the ABS and Traction control systems are not functional. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts me the driver and others at risk.

in 2022 the abs and traction control lights began to come on together, leading to loss of ABS and traction control in addition to not being able to use the cruise control. Vehicle was taken to the dealer to be serviced and they stated they would replace the HCU but would not replace the ABS module as they would only address one thing at a time. The problem continues to persist with the constant alarm ding and loss of abs and traction control as the lights continue to flash on the dash. This is a safety issue as you don't know when you'll have abs or traction control and if it happens while driving with the cruise control on, it abruptly shuts down the cruise control.

The warning lights for my ABS and traction control come on and off while driving normal driving conditions. Every time they flash it also has an audible ding that is very distracting. If I am using the cruise control when this happens the cruise control will turn off. The ABS system does not work when the lights come on. I am afraid I will be unable to stop. I took it to a local dealer and they confirmed that the HCU unit is defective and needs to be replaced at a price of $1300.

my family and I were on a trip out of town in the fall ,this oct, when suddenly as we were braking and the trucks break system started flashing on and off saying service brakes failure antilock the bells kept chiming we were scared to death with bell chiming on and off and lights flashing on the dash we stopped along the side of a busy highway camper and all and go what is going on should we continue or make a call for help. I shut the engine off and started it back up and everything was fine. so we started down the road and it returned after a couple of miles so we did this over and over but finally it just kept dinging until we made it home now two weeks later have not driven the truck now two weeks later . found out that this truck has a history of this . by the way this truck only has 13000 miles on it not driven in winters and all highway use. yes but out of warranty with a dangerous breaking issue at again 13000 miles

ABS / TRACTION CONTROL dash light error. Light code C0020-01. ABS CONTROL MODULE.

The ABS/Traction lights/Bell keeps alarming on my dash. The ABS HCU needs to be replaced. I have found out from research on line that RAM knows about this and chooses to do nothing about it. It mainly affects the 2017 and 2018 RAM 2500's. They switched manufactures for the ABS/HCU during those two years and the parts are inferior and constantly fail causing the ABS to be inoperable causing a serious safety concern.

While driving the service ABS System/ Traction control dash warning message appears on the screen & chimes at the same time. The cruise control then shuts off. At first it was intermittent then it was almost all the time. With winter coming soon the ABS/Traction control will be much needed. After going online, it seems like this is a common problem with 2017-2018 Rams. After going to a Ram dealer in my area they replaced the HCU/ABS pump. I feel that if this is a common problem it should be addressed with a recall to avoid potential vehicle control problems

Warning lights for ABS and traction control coming on with message to 'Service Electronic Braking System'. During this time the ABS does not work and cruise control stops working. Being a 2500 vehicle, it is commonly used for towing trailers as it has a towing capacity up to ~16K lbs. Suddenly not having ABS and traction control is dangerous. In July 2024 I was driving from Phoenix, AZ to East Texas with a ~10K lbs trailer and this issue suddenly started popping up. This is the first time I experienced this with this vehicle. I understand there is a known issue with the hydraulic control unit and the ABS modules for 2017-2018 2500 & 3500 models yet there has been no recall on these vehicles.

ABS and traction control warning lamps and messages appear with chime on and off message Service brakes system needed ABS only 26,400 miles

UNKNOWN Service electronic ABS system light intermittently comes on and off hundreds of times in a ten mile drive. I am reporting this due to finding out that this problem is affecting many many other 2018 Ram owners.

I am getting a warning saying to service the anti lock brakes and the traction control. I have had this same issue before and paid the dealership to fix it. Also when the warning appears the cruise control shuts off. I am concerned about the loss of control of the vehicle.

The ABS dash light and traction control light started coming on about a year ago. the light is intermittent with a ding sound. Some days it comes on non stop, sometimes it doesn’t come on at all. cruise control does not work, and “park rear” button is not able to get out of the off mode.

Intermittent Electronic Brake System and ABS Failure messages. Been dealing with this issue for over a year now. Dealership told me I had to wait almost a year before there would be a fix and that’s if I’m lucky. The ABS pump motor and the software are both faulty and Ram is aware of how to fix it, and haven’t. There needs to be a recall for issue, ASAP.

The abs and electronic brake control lights keep going off and no abs it also shuts cruise control off when light come on. I pull a trailer a lot and brakes lock up and no abs. Very dangerous ,almost rear ended a vehicle on the interstate because traffic stopped all a sudden. Cannot believe there isn’t a safety recall yet there are numerous complaints about this problem.

ABS module failure, only 63000 km had to pay $1038.19 to have it replaced at Parksville Dodge Jeep and 194.14 to read the code that we already had done at another auto shop. I have a case number [XXX]. I have sent many screen shots of other owners having problems, websites, recalls , 22v140000, 24v4150000. The ABS sensor came on our extended warranty ended in November 2023, we took it to a mechanic shop and the code C0020-01 came up (no parts only Chrysler can replace hmm that’s a problem why?)we then phoned Chrysler in Parksville and took it in and they showed same code and said needed to order part only one was in Red Deer Alberta. This is obviously an issue with this truck as there is a class action suit alleging FCA breached its warranty by using ABS and HCU modules of subpar quality known to be unfit for ordinary purpose and not disclosing this issue to customers at the time of purchase. These modules are prone to premature failure due to defective materials used in their manufacture. The lawsuit states FCA knew about the defect thru extensive pre-sale testing and numerous NHTSA complaints, there is a Technical Service Bulletin regarding the faulty ABS and HCU, despite issuing the TSB, FCA failed to issue a recall. The hearing is scheduled for December 17, 2024. We would like all costs associated with the replacement of this module paid for by Chrysler Canada. I want a recall issued for my vehicle and a cheque to reimburse me as this is clearly an issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I'm getting warning lights to service abs system and traction control, also cruise control and 4 wheel wheel drive will not engage. Dealer replaced abs control module while truck was under warranty and now at 58000 miles I'm having the same problem as I did when it was fixed earlier. This is a safety Hazzard and a recall needs to be done because theses vehicles were built for towing heavy loads and you loose your abs and traction control when trying to stop heavy loads.

Driving on interstate highway with cruise control engaged. Experienced rapid deceleration as cruise control disengaged without driver input. Received anti-lock braking error / service electronic braking system error. Was very dangerous situation to have occur unexpectedly and could have easily resulted in rear end collision or loss of control of vehicle. Received no warning prior to this failure. Issue has been sporadic but occurring more frequently. Vehicle has less effective braking in adverse road conditions. Never know when the anti lock brake system will be functional. A bump or vibration in the road can cause it to engage or disengage. Ram dealer service dept indicates Hydraulic Control Unit needs to be replaced. Looking online, I see this is an exceptionally common occurence in same year/make vehicles. So much so that the replacement part is backordered for months.

It's clear that my abs module is bad but it consists of three components. Mopar online doesn't have any components available to fix the problem. And the Dealer is selling the components separately and telling you which one they will sell you first and also at a higher price than what's available to you online

ABS/traction control warning lights and alarm intermittently on and off during driving, speed control does not work during the alarm cycle. ABS not working when warning comes on

While driving the PU with my camper in tow, the ABS and Service electronic bakes system warning were displayed on my dash. Then they went out. This process repeated several times over the next 3-4 minutes. Then the warning lights came on and stayed on. It remained that way until I parked on the side of the road and turned off the vehicle. I checked the undercarriage for any signs of any visible damage to the braking system. None was readily identifiable. Upon restarting the vehicle, all warning lights were extinguished. I proceeded to the campgrounds with out further warnings on this system. The next day, with out the camper in tow, the warning lights were again active flashing on and off for a period of about 3-4 minutes before they again came on and stayed on. This process repeated itself as I would turn off the vehicle and then restart it. Upon parking for the evening they were still on. When I started again the next day, they were off.

There seems to be an issue with my ABS and Electronic Braking System, because both lights are blinking on and off saying to service them. It started while I was driving down a gravel road, then will shut off and back on. I drove nearly 500 miles with the ABS and Electronic Braking System sending me this message off and on again. I noticed when it was on that my ABS was not working properly, but when the light was off it was. I tested it several times to verify that it worked when the lights was off and that it didn't when the lights were on.

The contact owns a 2018 Ram 2500. The contact stated that while driving at approximately 50 MPH, the Anti-lock Braking System (ABS) warning light illuminated. The vehicle was taken to the dealer who diagnosed that the ABS sensor had failed and replaced the ABS light. While driving approximately at55 MPH and decelerating, the contact applied the brake pedal but failed to respond. The vehicle was coasted to a stop. The vehicle was returned to the same dealer who had diagnosed that the calipers had failed. The brakes, brake pads, routers, and calibers were replaced. Approximately, 6 months later the contact noticed the vehicle failed to reverse. The vehicle app notes brake system failure, anti-brake system, ABS failure, and tire pressure failure warnings displayed. The vehicle was taken to the dealer who was unable to confirm a diagnosis however had assumed the reverse piston rods may have failed. The contact was informed the repair may take up to 2 weeks due to limited parts. The vehicle had not been repaired. The manufacturer was not notified of the failure. The failure mileage was 111,000.

Mileage: 111,000

ABS and service electronic breaking system lights all come on. I loose 4 wheel drive and cruise control as well as traction control. Happened at about 55000 miles had fixed now happened again at 95000 miles. Breaking is not as good as it should be!

I had warning lights come on service abs brake system. They replaced abs control module at around 30000 miles under warranty, and now at 58000 I'm getting the warning again. Abs doesn't work, traction control doesn't work and cruise control doesn't work. This makes the truck very unsafe especially when towing which truck is designed for. There needs to be a recall done on this problem.

Two years worth of "ABS" and "service electronic brake system" warning lights and bells going off. About 3 months ago they finally got a re-engineered ABS brake module installed and the light went away for about 2 months. Now they are back intermittently. Took it in to the dealership and they now say the HCU unit needs to be replaced as well. From reading RAM forums this is a known/on going problem with 2018 RAM 2500.

Truck only has 47,000 miles and are in need of replacement again. Looking this up online and there are tons of reports with the same issue on 2018 models. Brakes should be covered in a warranty or recall, IMO.

ABS LIGHT AND TRACTION CONTROL LIGHT FAILING AND NEEDING TO BE REPLACED

Electronic Braking System comes on and off after I hit a bump on the road. I am very worried about this issue. The dealer is not able to diagnos the issue unless it come on when I drop it off to them. This issues has been an issue for several months now. I checked online and several other Ram 2500 and 3500 owners are dealing with the same issue. Please help us do something about this.

The hydraulic control module and the ABS module are not working properly. This is a known defect on these trucks. When the lights are on, the ABS will not engage. I have had the truck at the dealer, and they said since there is no recall, they can do nothing. This problem was addressed in a recall for 2020 and newer trucks but not for 2018 trucks. I know of two class action lawsuits, one in Texas and one in California.

ABS does not engage in emergency stops. Truck has been reviewed by a dealer noting a surge of HCU and ABS units malfunctioning. Parts are on a year lead time in order to repair.

For the last few months, my ABS/Traction control lights on the dash board have been flashing on and off over bumps and even flat road driving. Over the last few weeks, the ABS/Traction control lights have been staying on constantly. I am nervous to tow a heavy load with these lights illuminated since this is dealing with the brake system. After some research, I have discovered this is a huge issue with the RAM 2500 and should be fixed by the manufacturer

Starting about a month ago, I started receiving a warning about servicing my electric brake system. Was very intermittent. Spoke to the dealership and they said if it wasn’t happening right then, they couldn’t read the codes. If the light went out, I could wait to bring it. Went on a trip, and it started happening more frequently, but still intermittently. I tow a 7-ton fifth wheel, which made me feel very unsafe. Sometimes happens moments apart, and sometimes hours apart, and it always knocks out the cruise control. Looking online, I found that this is a very common occurrence, and that I should report it. I did not have an accident, and tried to do my best to drive safely so I could get home.

ABS / Traction control error intermittent alert.

Loss of break performance. Traction control and abs warning lights come on intermittently. This is the second time this has happened. Had abs module and hcu replaced once already.

ABS/TRACTION CONTROL LIGHTS and alarm started in January 2022 the vehicle only had 21,460 miles on it so I took my 2018 Ram to dealership to get looked at and they diagnosed the faulty part as ABS HCU/MODULE. The vehicle was under warranty so they fixed it for free. October 01 2024 the same thing happened vehicle with 38,000 miles all the lights started flashing and alarming while I was towing my camper I've heard that when this happens it disables cruise control and the trailer braking system. THATS VERY DANGOUS WHEN PULLING A 8,000 POUND CAMPER!! Now I've heard that the part is on back order and 'm lost on what to do.

the ABS light will come on while I am driving along with traction control turning off with a ding. While the warning comes on, the cruise control will turn off. It will turn on and off several time during a drive and will ding when it comes on. Very distracting and annoying and distracting. the dealer will charge me to look at it to find a reason. Truck has 37,000

abs light and traction controllight on

Traction control light and ABS light come on and go off intermittently will cancel my cruise control.A warning ding accompanies this.It does this frequently while driving.Electronic braking warning comes on the dash.

On 10-01-2024, I took my 2018 RAM Truck for service at the Warrensburg, Missouri Dealership. The reason was due to service lights coming on in the truck to tell me the ABS and Electronic Braking System had issues. The dealership service department replaced a faulty HCU and the "Control Anti-Lock Brake System". My truck had 69850 mileage when the service lights came on. This is the second time, the HCU has been replaced due to the same issue in 04-21-2021, when the same truck had 30945 miles. The dealership explained this is due to RAM contracting the HCU part from a manufacture that proved to be bad. They have now changed manufacturer and the new part is being installed. A quick search through the internet shows this is an issue in RAM trucks over the years with two lawsuit in two different states. The loss of the braking systems, especially when hauling trailers and campers can cause serious braking issues. Why has there not been a recall issued on this HCU? Not only unsafe, but not being warrantied by RAM, my repair bill for their error in manufacturer, cost me almost $800.00. Please investigate before a serious accident occurs over many years of these RAM trucks using a faulty HCU.

The ABS system lights and dinging keep going off. Started months ago. Stopped for a while then does it randomly sometimes a lot, sometimes once in a while. Theirs is no rhyme or reason why or when it dies it. Stopped at dealer and they said this year was having problems and they have been back ordered with parts and have no idea when they will be in.

Currently I own a 2018 RAM 2500. I am the original owner and do regular Maintenace on my truck. The ABS & Traction control light flashes on and off consistently (Very annoying while driving). I have brought my truck to the mechanic and told me I have to wait on a part that is on "National Back Order".... No dealership has the part, and no website has the part. Only place to be found is on eBay used with no warranty they work, or proof they have been refurbished. From what I have been told it is the EBCM. I did research to try and find the part. No where has it, and nowhere to be found. This is where I found out it is a frequent problem over a lot of people. I see RAM has a recall for the same issue with 2019 & newer, but no recalls on the 2013–2018-year model trucks. This truck is my everyday driver, and I need it fixed....

ABS and TRACTION CONTROL warning lights appear and disappear. Timing of warning lights have no discernable pattern. Vehicle has had no collisions and only 120,000 miles. Vehicle will be going in for inspection at garage.

While driving the ABS light and traction control light come on and go off randomly. I am afraid the brakes will quit working.

Anti-lock Braking System module failure due to poor/defective manufacturing and/or parts. This is a known issue with 2018 RAM 2500/3500 trucks. Safety is at risk due to failure of the ABS module which affects stopping performance. The RAM delear has diagnosed the issue as intermittent. The warning lights go on/off constantly while driving causing a distraction as well. This part should be recalled.

My ABS light and ESC light come on intermittently and at time repeatedly on and off. Also a warning comes on stating either "Servcie ABS" or "Service Electronic Braking System". There are no codes when scanned.

While under warranty (no paperwork available for exact date), the ABS and Traction Control warning light would intermittently turn on and then go off. It was taken to the dealership and repaired under warranty. I now have 40,000 miles on the truck and am again having the same issue.

the ABS light and electronic braking intermittent flashing light Code C0020 ABS disabled when light is on New ABS motor required part number 68143491AB

Service ABS and electronic braking system warnings are on. Cruise control and traction control are disabled.

ABS light comes on, antil lock brakes no longer work and Cruise inoperable. The ABS/HCU module has gone bad again, the dealer has replaced it 2x already. This is the third time it has happened and vehicle has 25989 miles. Dealer states this is a KNOWN issue and parts to repair are unavailable,.

I purchased this truck new in 2018. I soon started having problems with very hard shifting and slamming into gear. It has been to the shop and diagnosed and continues to do it. They cant seem to fix it. My ABS lights and alarm are sounding non stop. This happened within 5 miles of my warranty being up. I did diagnostics and they wont cover it and want to charge me 1500 plus i have to wait 8 months for the part. This is an ABS issue and a safety issue! I also get the DEF failure notice telling me its going into limp mode. This has happened multiple times. I still only have 36k miles on it. I was told this ABS issue was now covered and the factory is doing extended warranties based on these problems. But the dealership says they know noting about it and that i have to bring it back in AGAIN to diagnose which i have to pay for AGAIN. I hate this truck and i have had nothing but problems and no one will help.

The hcu control unit keeps going out, fixing to be replacing 5 one on this truck. Lost all cruise control, and 4 wheel drive functions.

ABS AND TRACTION CONTROL LIGHTS APPEARED ON DASH PUTTING SYSTEM INTO DEFAULT MODE , APPEARS TO HAPPEN ON AND OFF AT WILL,

Abs module/motor failure. Second time at 60000 miles also failed under warranty and replaced at that time.

At approx 24K miles my RAM 2500 had an intermittent anti lock brake/ stability control malfunction and displayed a "Service Brake System" message randomly while driving. The issue was "fixed" under warranty. Currently my RAM has 54K miles on it and the issue has reappeared. I know their is a safety recall that exist for 2019 and newer trucks but believe the problem may exist on trucks built prior as well. Either way, an intermittent anti lock brake/ stability control malfunction seems to exist on the 2018 models, and based on info posted on RAM forums, it is a common malfunction.

ABS light and traction control keeps coming on. Dealer says there is no recall. If you look through the Internet, you’ll find thousands of complaints of this issue. I find this to be a major safety problem, I haul a heavy trailer with this truck and if my ABS and traction control fails, this is very dangerous.

When driving the ABS and Traction Control caution lights illuminate. I went to the dealership and they said it was a bad ABS pump and was a little over $1200 to replace. The truck only has 24k miles on it.

My truck throws a abs traction control failure code. This happened in 2022 and was fixed by the dealer because my truck was still under warranty. The hydraulic control module was replaced and the abs control module was replaced. I have just received the same error lights on my truck again on 09/27/24. My abs and traction control are disabled. This has to be a faulty design or bad part. My truck is now out of warranty. There is no way this issue should have happened twice on a truck this new unless MOPAR is making or using bad parts

Receiving the "Anti-lock brake system Warning" comes on frequently. Once cleared, the sensor or module either fails again, or provides the erroneous warning. Happens frequently, at least once every 1-15 miles, whether vehicle is moving or not. Dealer mechanic says this is a known problem with 2018-22 Ram trucks. New replacement modules are not available, and those who have had them replaced reported reoccurring problem within a year.

ABS failure which also turn traction control off. My safety and the public in general is at risk if my brakes lock up on a slippery road, especially if towing. The problem was confirmed by my mechanic, parts are impossible to get. Tons and tons of complaints online and in forums.

ABS lights come on in dash and cruise control shuts off. Diagnostic found ABS HCU and ECU faults.

Service electronic braking system / service ABS light comes on and off when driving on on bumpy roads and when turning. It usually stays on which disables traction and it has cause me to almost spin out when accelerating in wet conditions.

Abs module failure causing cruise control shutdowns and potentially causing an accident as well as transmission issues. Yes it’s been confirmed by an independent shop . Not by any others. No warning before just straight failure. Vehicle is available currently for inspection if wanted

Thai dang ABS going out in these trucks. And still no fix. Went out when going down the high way. Kicked out Cruze co trip 4 we and all sensors. Almost died this is crap that nothing is being done to fix this and get a part that fixes this for the customers that bought these trucks. I have a 50k truck I can’t drive. Have not driven it’s in almost a year now. SOMETHINGS NEEDS DONE

Abs mod and pump wet bad around 30,000 miles. I replace both and now 2 years later and 52,000 both parts are bad again. Looks to me there is a problem they haven't fix and keep selling parts that they know is going to fail. This is not a cheap fix and something needs to be done about it

Truck is experiencing a what started as a intermittent and not constant failure of the ABS and Traction control with flashing lights and constant chimes. Making the vehicle dangerous to drive.

Internal fault in hydraulic control unit. They are replacing this when the part comes in. Have no antilock brakes or cruise control. If that doesn't fix it, then they will replace the module.

Service electronic braking system continues to flash along with Service Antilock brake system--This is a failure of the HCU (hydrolic control unit) that should be a RECALL. Thousands of people are having the same issue.

My ABS light came on and then shortly later I noticed that my stability control system was disabled and its warning light came on. I also lost the ability to use my cruise control. Took vehicle to the dealer and they determined that the ABS Control unit needed to be replaced. They trouble shot the issue and replaced the ABS Hydraulic Control unit. This repair is for the same recall as 85B for Ram 1500's.

Continually getting ABS warning and "Service electronic brake system soon" warning. Electronic Stability Control suddenly shuts off without warning to include cruise control if engaged. ABS and ESC lights remain on most of the time with constant chiming. This is a widely known problem. Recall just came out for later model years but not these.

1. ABS SYTEM FAULTS, NO KNOWN TRIGGERING, CONTINUOUS FLASHING, RESETTING, AND GOING OFF AGAIN. DROPS THE TRUCK OUT OF CRUISE CONTROL. 2. I WOULD SAY YES, MY SAFETY AND THE SAFETY OF OTHERS ARE PUT AT RISK WHEN THIS HAPPENS, ESPECIALLY WHEN THE TRUCK DROPS OUT OF CRUISE CONTROL AT RANDOM UPON ONSET OF THE ISSUE. 3. ONSET 17SEP24, CONTINUIED 18SEP24, TWO DAYS IN A ROW NOW. TROUBLESHOOTING CALL HAS BEEN MADE TO DEALER THIS AM FOR FOLLOW ON DIAGNOSTICS. CURSIARY RESEARCH DONE THIS AM SHOWS MULTIPLE REPORTS OF FAULTY ABS SYSTEM PARTS AND MODULAR ISSUES BEING REPORTED, CLASS ACTION LAWSUITS, NHTSA REPORTS ETC. 4. NO 5. YES, ABS SYSTEM FAILURE WARNINGS, ABS FAULT LIGHT WITH SYSTEM CHIMES

I am getting a code "C0020-01" causing my vehicle to not brake properly, traction control is deactivated, constant chime of the warning system, loss of cruise control and unstable driving conditions when driving on wet roads. Researching the code has led me to forums on the internet which shows there are several incidents of this issue common to the 2017-2018 Ram 2500 vehicles.

ABS brakes module. Failed at 60k miles and has been on back order for almost 2 years. So I have not had ABS brakes in almost 2 years now. Seems to be a major problem. I know of 5 people with the same issue.

The ABS warning light and alarm come on while driving. Loss of ABS and cruise control, near rear end collision by following vehicles on the freeway while using cruise control. Ram knows they have a problem with 2017 and 2018 2500 pickups. Why no recall? Safety problem!

The system that is malfunctioning is the braking system, ABS module, or HCU. The traction control light and ABS light intermittently flash, disengage cruise control and the antilock braking system. The lights never stay on consistently but rather they come on and off without any pattern. This same issue happened a right at 2 years and 30k miles previously which the truck was then taken to a dealership and supposedly replaced. However, the same issues are happening again with no indication as to why this part keeps failing. Truck has less than 90k on it currently, mainly highway use. There have been no inspections done, however, I plan to take it to the dealer in the near future.

Abs light and traction control warning light constantly coming on and off while driving and a warning sound playing every time the lights come on in the dash, which is very annoying and frustrating. The truck is under 30 000 miles and unfortunately is out of warranty. I don’t drive this truck very much and having this kind of problems with it is totally unacceptable.

The ABS HCU has failed again this is the third time. The brakes feel spongy and the cruise control and 4wd does not work. The cause is unknown faulty design of parts. I don’t remember the mileage of the first or second failure.

“Service AntiLock Brake System” and “Service Electronic Braking System” lights flash intermittently while driving. ABS, Traction Control., and Engine lights up on dash. Code is C0020. It has done this several times while driving. Vehicle has just over 34,000 miles on odometer. Its a common issue apparently known by Stellantis and they had changed supplier and part number.

Abs light and braking system needs servicing and found out it is a common problem with Dodge Rams , scanner shows ABS pump motor control general electrical failure

Vehicle will display Service Electronic braking system randomly throughout driving the vehicle. The cruise control is not available when the code shows up. Also, the ABS and Traction Control lights pop up. The problem will shortly go away when I press the brakes all the way.

ABS been down since July,2023,alarm dings constantly, dealer says no parts available, and Chrysler is no help

ABS service light was intermittently coming on and off for a period of time and now is constantly on. This results in constant beeping and also prevents the cruise control from working.

Vehicle has a control module failure causing the ABS, Traction Control, Cruise Control and other braking systems to intermittently turn off and on. The vehicle has been brought in for this issue and we have been told they are unable to get parts to replace the module at this time. This has been an ongoing issue for multiple years, with the failure occurring at a higher percentage of time the vehicle is driven now.

ABS needs service. Was quoted 2k from Dodge for repairs. As well as electric brake system not working Chrysler told me it is safe to tow my 10000 lbs rv with the errors and no ABS.

I bought my 2018 Ram Truck in 2019 new from a dealership. the first sign of a problem started at about 25,000 mi. It started sending tones with the message "Service Electronic Braking System" and "Service Antilock Brake System". It would toggle between these two messages and sound warning tones while the truck is in operation. The first shop I took it to replaced my carburetor. That was not it. I then took to a Diagnostic Shop and the message from the computer read: ABS pump motor control general electrical failure. On the dash it also shows the icon for slippery road conditions. Looking on the internet i realized that this is affecting 2017's and 2018's. There are a lot, maybe all of them being affected by this potentially dangerous malfunction.

Constant on and off of abs and traction control due to abs module and hydraulic control unit failure. It’s a known issue by fca.

Driving on cruise control the Anti-Lock brake light came on causing the cruise control to turn off at highway speeds. The anti-lock brake system, cruise control and traction control all quit working. Warning light went out and then all started working again. Very intermittent problem at first then started getting more frequent. After research I found it is a known problem on 2017 and 2018 ram pickups. The parts to fix it are revisions from the original and known bad but no service bulletins or recalls. There has been a recall for 2019 and later but Ram is not addressing the earlier problems.

CONSTANT PROBLEM OF SERVICE ELECTRONIC BRAKING SYSTEM AND TRACTION CONTROL LIGHT GOING ON AND OFF. HAS BEEN HAPPENING FOR THE LAST 6 MONTHS ON A TRUCK WITH ONLY 25,000 MILES ON IT.

When driving and hit a bump the abs/ traction control lights come on and off. Does this consistently with bumps. Problem is not a wheel hub or sensor, when scanned it comes back as a C0020-01 code abs pump motor control general electrical failure. Safe to assume that the brushes within pump motor are sticking and failing to slide properly.

The anti-lock brake control unit failed while under warranty and was repaired and it has failed again with only 53737 mi. When the ABS light comes on the traction control light comes on and the cruise control quits working. Seems very unsafe. Don't know if I can afford to fix it and no parts are available.

Truck chimes and says service ABS brake system and service electronic brake system. Traction control and ABS light pop on and off intermittently while driving.

Brake module malfunction kicks out cruise control and dings constantly. Seems to be a recall for other years but this year is missing?

ABS and traction control modules randomly deactivate leaving 20,000 LBS of truck and trailer without the ABS and traction control system to aid in emergency stopping. This is A KNOWN ISSUE to Ram who refuses to acknowledge and properly recall and provide replacement parts on some of the most heavily used tow vehicles.

At 41,000 miles “check abs and electronic brake system” warning started coming on causing system failure to vehicle. Vehicle was taken to dealer with it requiring replacement of Hydraulic Control Unit and ABS control unit. Now at 71,000 miles same problem is occurring with cruise control deactivating, traction control failure, and ABS failure without warning. Apparently this is a known issue by RAM that continues to cause system failures across the vehicles sold between 2017 and 2019. To date I’ve not had an accident due to this issue but it is definitely a safety issue that RAM should be forced to issue a recall to correct! Please respond with updates. Thank you…

Abs light comes on and off all the time. Randomly and hitting a bump. Hitting bumps causes an intermittent chime and notification alerting me that the Antilock Breaking System and Electronic Breaking System need service. It doesnt seem to matter what speed you are going. Upon research online looks to be a common problem that RAM has. There is an issue with pump motor electrical brushes making contact which causes this issue.

ABS control module fault code. Seems to be a lot of people having issues with this on 2017 and 2018 year model trucks. A class action would be nice or some sore of solution for ram to make a permanent fix.

Second time my antilock brakes module has gone bad with 56000 miles not covered under warranty. Cost me $1700 to fix a little over two years ago. It went out again today and they said they wouldn't cover it. I have been reading about this and it's a major problem with many Ram trucks. I feel it should be taken care of on a recall and not having to pay every time it goes out. Ram knows this is a big problem and not doing anything but taking my money. Thank you

Two issues with my truck. #1. The ABS HCU was replaced under warranty once. I am now at 75k miles and it is doing the same thing again. Difference is I'm having to pay for it. #2. The Clock Springs has been replaced once already and now needs it again. I paid the first time and am now having to pay again!!! Absolutely not acceptable!!!

Driving in traffic a vehicle in front made a sudden emergency manuver. I braked to avoid, the ABS warning light flashed and beeped "service abs system". The failed abs system nearly caused an accident. Took to the dealer, and they replaced the failed abs module under warranty at 20k miles on truck. Now, with 34k miles it failed again. Parts are reported to be on national backorder. Friends with this model truck are experiencing similar failures. Fact that these trucks are often work trucks, towing etc make these failures very serious. I urge you folks to push Ram to recall these defective parts before someone is killed.

Abs light comes on and off all the time. Randomly and hitting a bump. Code is c0020-01. The cruise control is disabled when this occurs. Also I assume abs would be disabled also. Took truck to dealer to look at. They tell me there is no engineering fix at this time for this issue and no parts available. Upon research online looks to be a common problem that RAM has. There is an issue with pump motor electrical brushes making contact which causes this issue. Truck is a fairly low mile truck.

Vehicle warning lights and message on dash keep going off and on indicating need to service the ABS system following a break-job. Warning comes and goes as many as 30 times per minute. Anti-lock brakes and traction control are currently inoperable. Dealer cannot diagnose between electronic ABS module and hydraulic control unit blames one or both as culprit. Module is on back-order from Mopar due to this being a widespread and prevailing issue and they even suggested the matter has been escalated to their engineers for a more robust solution. My ABS pump module was replaced under warranty at 90k miles. I was quoted $1800 to repair upon part availability. I would appreciate the NHTSA investigating this matter for eligibility of a forced recall with Ram to pay some or all costs to remedy.

My abs/traction control and electric braking system warning light has recently cone one for the third time. The first time it was repaired around 3,200 miles, the second time was around 32,000 miles and now around 72,000 miles. The light flases randomly and when it does i can't use my cruise control.My vehicle can be inspected any time.

Hitting bumps causes an intermittent chime and notification alerting me that the Antilock Breaking System and Electronic Breaking System need service. Both the ABS and traction control lights are illuminated. I contacted my local dealer and they indicated that this isn't an immediate safety concern and is due to an electrical issue for which they haven't solved. They quoted me $1,600 for the replacement of the Anti-Lock Brake System Module and Hydraulic Control Unit. After some online research, it seems that this is a common issue with many resulting in total brake failures. A potential brake system failure should be a recall for obvious reasons.

ABS control module/pump very common problem with this year truck that Fiat/Stellantis needs to address.

SERVICE ABS BRAKE SYSTEM WARNING LIGHTS.THE ABS UNIT WAS REPLACED 6-7-2022 AT FELDMAN DODGE WHEN THE LIGHTS CAME ON AT 15525 MILES.NOW THE LIGHTS ARE COMING ON AGAIN AT 30000 MILES THIS SEEMS TO BE A KNOWN RAM PROBLEM.PLEASE ADVISE [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Service Electronic Braking System and Service Antilock Braking System lights have been popping on the dash for the last two months nonstop at random times. Sometimes I can drive for hours and not see them, then other times they flicker on and off constantly. It’s very frustrating as my truck has only 27000 miles for a 2018. I’ve checked rear wheel sensors and found a tiny bit of metal shavings which from what I’ve read could be wheel bearings but still don’t know a for sure answer. I’m about tired of chasing down this rabbit trail. What caused this was I was backing my trailer and I started to spin a little and the lights came on so I clicked into 4x4 and lights stayed on. I turned the truck off and thought nothing of it and next morning truck had no lights on that day. But ever since then I’ve been plagued with them going on and off.

The abs/traction control lights are coming back on again. The abs control module and the hydraulic control unit were replaced when the truck had 34,000 miles. Now it has close to 60,000 and it has started doing the same thing again. Talked to the dealer and they said it would be close to $2000 to do the repair this time since it isn't under warranty. I have seen many of this same problem in a lot of the ram or cummins forums and feel this is a known issue and should be recalled. You lose the abs and traction control when these are out but it is intermittent. Fortunately, I haven't had an accident from this so far but could very well see how it could cause an accident. When my traction control was out the truck fish tailed on a wet road.

ABS pump motor control and anti-lock brake hydraulic unit is out again. first time replaced at dealer on 12/27/2019 second time8/10/2022 and now ABS light flashing again for about 3 weeks now with code c0020-01. This should be a recall it is very dangerous to be hauling heavy equipment with this reoccurring problem approximately every 20,000 miles or so.

The issue with the Electronic Braking System and ABS has worsened. The two warning lamps are almost constantly on, or rapidly come on and go off rapidly. If I'm towing a trailer, all braking is lost momentarily - brake pedal to the floor - including the trailer brakes. The trailer brakes do not return until an ignition cycle, if the warning lamps stay off, that is. The dealer says no parts are available, but won't even take it in for troubleshooting or attempted repair. This truck scares me. This has been an issue for about two years and 20,000 miles.

ABS/HCU problem. Code C0020-01

Code C0020-01 appears and ABS service light appears - the vehicle is equipped with a defective and dangerous hydraulic control unit (HCU) module and anti-lock braking system (ABS) module. Anti-lock braking, traction control and speed (cruise) control are inoperable. Causing a safety concern

Abs not functioning. Multiple online forums with complaints for faulty abs module and pump. Abs pump not working. Scanner will not communicate with abs. 2017-2018 Ram 2500 very common known issue.

The Hydraulic Control Unit Chrysler part number 68143491AA failed and been replaced previously on my vehicle. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. The problem has been reproduced by my local dealer and the vehicle will be dropped off for evaluation again this week. The manufacturer has not evaluated the product. Abs and traction control lamps are intermittent when the issue occurs.

My 2018 Ram 2500 had a ABS/Traction Control warning light and I took it back to the dealer 01/12/21 and had the the HDC replaced. Mileage on the truck at that time was 16,220. Warranty covered the problem. Problem returned and took it back to the dealer 04/28/23. Mileage at that time was 24,824. Was told that it was no longer under warranty. Was told the part only had a two year warranty. The dealer didn't have the part at that time due to numerous problems with this system. Truck only has 29,022 miles at this time. I haven't had the part replaced and just have to listen to the warning chime continually sounding. Researching the internet reveals this problem is very common and should be a recall with the manufacturer fixing this known problem. I have the Dealer Service Documents.

ABS light and traction control light randomly come on while driving and sometimes apply the brakes without warning. Scanned for codes and was given a codes for an abs module failure. This seems to be a very common failure on these vehicles and should be addressed with a recall as it is very unsafe. I have almost been rear ended several times.

Abs traction control light

I have had the ABS/HCU replaced a year or two ago and now I’ve got the same issue again today 8/30/2024. Code C0020. I have to wait to get it to the dealership after the long weekend and holiday on Monday so they can check it out. Lights flashing in the dash and cruise control is not working when this happens.

error code c0020-01abs/hcu pump motor control. i am one of thousands with the problem of getting abs and traction control lights flashing on my dash of my truck. it takes away my abs brakes my cruise control and the trailer brakes. i use my truck to pull a large trailer which has forced me to stop using my truck and it is now useless to me.please help us all and force ram to recall and fix our problem. my truck is a 2018 2500 and has 18,000 miles on it. and now i can not use it.

Vehicle gives warning on the dash for ABS and anti skid off. Along with an audible warning. the warning on the dash states the anti lock brake system needs repaired. While this is active the cruise control does not work as well as the anti lock and anti skid system.

ABS /Traction Control warning chimes and lamps providing erratic behavior and constant noise/distraction. In doing some basic research, this is a known issue for these trucks.

ABS hydraulic control unit motor failure, occurred at 25k miles, just outside of 3 year warranty as I bought truck used from a dealer. Intermittent loss of ABS and traction control with no warning, and constant dinging sound while driving as the motor reconnects and disconnects. Currently have 40k miles, have not repaired as from what I’ve heard from other owners and seen online, the repair is $1000-$2000 depending on dealer, and the repair may only last 25k miles if the part installed is of the same build quality. Many owners have resorted to replacing the ABS pump motor with parts from other makes/models of vehicles, as it seems the Mopar part is dealer-only availability at this point. I have found a dealer source that has a new upgraded part number that I will be ordering from and finally replacing, but I have no hopes that the part will last any longer than others have seen. I am only replacing the part as there is a class action lawsuit pending. My hope is that a safety recall be issued, as this is a prevalent problem in the 2017-2018 Ram trucks.

C0020 error code. Required replacement of ABS system's HCU (hydraulic control unit). Vehicle's ABS and electronic braking systems warning systems would flash. Loss of cruise control when the warning light came on. Vehicle lacked ABS made especially dangerous in wet road conditions while towing.

My ABS and HCU modules are both bad. Leaving me vulnerable to locking my brakes on wet roads. My traction control will not work because of this as well. This is unsafe.

While driving pulling a trailer the service antilock brake system light started to flash on and off sporadically the entire time i was driving. It does it now every time i start the truck. Doing research it's a know problem. The truck has 43k miles. While the light is on the braking is not what it should be for a truck that can haul the loads it's supposed to. Definitely a safety hazard.

Vehicle constantly displays “service electronic braking system” message. ABS light will not turn off. Dealer tells me there is nothing they can do for me and they have multiple customers with 2018 RAMs with same issue and replacement parts are not available.

The Service Anti-lock Braking System warning lights and audio alarms come on almost constantly at times along with the cruise control failing, a common problem I understand which Dodge Ram has to be aware of. This truck has only 7000 miles on it!

ABS and TCS modules failing cruise control and abs unavailable when lights appear on dash. Vehicle not inspected by authorities or dealer at the moment will take to service center shortly.

The service electronic brake light and traction control light on my 2018 Ram 2500 keeps going on and off while driving. This started with only 12,048 miles and 6 weeks over my 3 year warranty. Research shows that this is a common issue with 2018 Rams and newer. Thousands of complaints have been reported and there are several Class Action Lawsuits regarding this issue in several States. Also being reported, is that this issue causes towing problems and the cruise control to malfunction, so I don't dare to use either when traveling. Even with repairs, if you can find the parts, some owners are reporting several repeated failures. You can't replace defective parts with more defective parts and expect a resolution to the problem. Though I have not had brake failure yet, and with only 27,000 mile, it is always on my mind while driving. I don't feel safe when driving my vehicle, hence the low mileage. Chrysler needs to be held accountable and a recall needs to be issued for all makes/models/years having this issue.

Abs module failure. Traction control failure Stability control failure. Module replaced by dealer once under warranty and failed a little over a year later. Dealer would not replace defective unit stating it was out of warranty.

ABS Pump Motor Control: General Electrical Failure code-C0020-01

abs warning light comes on. Dealer stated it cannot be repaired.

My abs system is not working the ETC is not working was told this is because of the abs pump and abs computer. Most safety components related to brakes not working. There are over a thousand complaints to Chrysler about these trucks and still no recall. Please help.

Driving the vehicle the alarm dinged and the panel displayed service ABS system, service electronic breaking system. Would go off and on flashing intermittently

The "Service Electronic Braking System" warning comes on and off intermittently with an annoying "DING" while driving. It never stays on and always just comes on, DING, and goes away but repeatedly. It will eventually go away after driving a bit but then comes back unexpectedly. This also disables the Cruise Control. There are tons of complaints throughout the RAM forums and I see a lot of complaints filed here on NHTSA. The dealer is obviously very aware of the problem as the replacement parts are not available except for months of waiting, if at all. The dealership has not only stated the part is a long lead item and on back-order but it will be $1200 to $1600 for replacement and that part may fail as well!

The service electronic brake light and traction control light keeps illuminating periodically while driving. The code was read and ELECTRICAL FAILURE C0020-01-ABS PUMP MOTOR CONTROL was received. This is the second time this occurred and the first one was replaced under warranty.

The abs control module and HCU are faulty . No parts have been available for a fix. I have now been driving a truck in the north with no ABS , 4 wheel drive, cruise control or traction control. This truck is a hazard to everyone on the road but with no parts it’s hard to fix it. I only have one vehicle. Tons of people have the same issue and nothing is being done. Ram won’t do anything, stallantis wont do anything. It’s just crazy

The ABS light keeps coming on/off when I’m driving saying service the abs module or the equipment.. I did some research about it alot people complain about this problem.

2018 Ram 2500 with 6.7L Cummins Diesel The ABS warning light and traction control warning lights come on and go off constantly along with a message to check the braking system. The problem is intermittent. It might happen once in a trip or it might have 50 times in a trip, but it always happens. Losing traction control and ABS braking puts me and my passengers in a severe risk of injury as the vehicle will not be able to be maneuvered or stopped in an emergency situation or during dangerous road conditions. A search of online forums has revealed hundreds of people reporting the same issues with their vehicle.

ABS module failure

2018 Dodge 2500 w 75K miles. "Service ABS" and "Service Electronic Braking System" warning lights coming on intermittently for appx last 1.5K miles. When this happens, it disengages the cruise control when set, or keeps it from being engaged when unset . Noted yesterday that Braking performance is now lessened- slightly increased stopping distance noted when pulling an appx 3K lb trailer (no trailer brakes), which i regularly tow. Brake fluid levels good, brake shoes/calipers/rotors in very good shape.

Getting the Service Electronic Brake System, Traction Control, and Anti-lock Brake System. First noticed these alarms a couple years ago but they cleared by themselves. Sometime this 2024 Spring, around 70k miles these alarms started again. This time the alarms are nuisance going on and off multiple time a minute all by itself. Cruise control won’t work when alarms are on. When I checked forums, seems like there is a problem with these modules. The supply of the parts is a problem also. I ordered the parts from Mopar and after I paid for the parts and received an order number. The next day Mopar cancelled my order tell me to go to the dealer. Seems like Mopar is monopolizing these parts.

For the last 3 years the ABS and traction control warning lights come on and off intermittently. This occures every time the truck is driven. I have replaced the ABS control module and the Hydraulic pump unit with new OEM parts and this issue keeps coming back. Driving and towing heavy loads this truck is extremely dangerous (without a functioning ABS system). A recall is urgently needed!!!

ABS and traction control lights came on. Brought to my mechanic and they spoke with Dodge who started they put a freeze on selling the parts and currently have no fix.

17427 miles 68143491aa control anti-lock brake system replaced 68347098ab module anti-lock brake system replaced code found c0021-01 replacement of the hcu and module. 12/30/2019 At 80,460 mi same code and information appeared again. 12/23/2022 No ABS brakes /no speed control continues currently 111,400 miles an indicator lights stay on.

Electronic braking system alarm and antilock brake system alarms keep coming on and off. Based on research HCU is faulty.

ABS Traction Control Failure. Dash lights come on ABS and Traction Control do not work after that. This started as an intermittent issue and now the lights are on all the time and there is no longer any ABS or Traction Control on the truck which I feel is a major safety issue for this truck especially when pulling a loaded trailer.

The ABS system module has failed leaving me with a large truck and no anti-lock brakes or stability control. This is a known issue on my truck (I found out on line) putting people in danger. The parts are back-ordered and they want $2300 to fix it. My truck has <60K miles on it. The warning lights are on and the dealer told me to just "pump my brakes" if the lock up - like "in the old days before abs." Please make them issue and recall. This is very unsafe.

ABS and Electronic braking system error. Traction control not working due to system malfunction.

On 8/10/2024 at 3.10 PM while traveling 68 mph on an interstate, the vehicle started displaying Service Electronic Brake System and Antilock Brake Failure warnings. This also shut off the cruise control system, causing a sudden and unexpected loss of forward momentum. The warnings would reset and then come on randomly while travelling.

Like most other owners I too have the annoying ABS failure and traction control lights dinging on and off constantly. So no traction control or ABS. You also lose cruise control We are paying for a recall as the dealers want $2000 to $2500

Intermittent failure of ABS system. Causing cruise control to suddenly shut off at highway speeds as well as having a non-functioning ABS system.

Got an ABS fault for a corrupt hydraulic brake unit. So I replaced the unit at the cost of $200.. once replaced I still had an ABS light, traction control light, Brake light. Reading the codes it would tell me that both rear wheel speed sensors failed to compare. Ultimately I got a check engine light for wheel speed sensor 1 failure. So when I rest the code it clears the lights and I lose the speedometer for 25 plus miles. Also renders the 4x4 feature useless on the truck. I took it to the dealership on 8/8/2024 and they attempted to do an update to the ABS module. After the update I lost the speedometer again. I was told that the ABS module will need replaced at the cost of $600 plus labor and program time.

Driving in normal conditions .. even leaving my driveway ABS light comes on and traction control light comes on. and flashes randomly. Sometimes in doesn't come on for a bit but then will flicker on and off.

The ABS and Electronic braking system has failed in this vehicle. While driving the vehicle, the ABS light will cycle on and off consistently. When the light is activated, the cruise control also becomes ineffective. It has been determined to be the ABS Module failing. This truck only has 100,000 miles on it. When I contacted multiple dealerships, they informed me that they cannot order a replacement part as they do not exist from the manufacture anymore. There are no aftermarket options. After contacting Fiat Chrysler Association (FCA) they informed me the parts were pulled from dealerships and they are under engineering review for replacements with no timeline available. This is a 10,000 lbs vehicle with a 16,000lb tow rating. It is unacceptable for this to continue failing on a truck that when combined with a trailer can be totaling 26,000lbs. If this system fails while towing, the result will be deadly to anyone involved. I've spoken with hundreds of others with this same failure on the same truck. It is unacceptable that we cannot drive our trucks safely, we cannot fix them because parts don't exist, and we cannot sell them because they are undriveable and unfixable.

The ABS module and HCU are failing on these trucks. They’re causing the brakes to lock up, and the traction control system to automatically turn off, disables cruise control, and there are thousands of reports of this all over the internet.

The electronic braking system/abs light/traction control light constantly comes on and off every few seconds when driving. Having intermittent loss of anti lock braking system is a hazard.

Intermittent ABS brake error code C0020 - "Recirculation pump general electrical failure". This error occurs then clears within seconds while normal driving. No special weather conditions, road conditions or temperatures noted. May drive 5 miles, 50 miles or 500 miles before error occurs again. Only 6150 miles on vehicle. Repair parts scarce or not available.

ABS light and traction control lights are on and off with the service light on dash on and off.When the abs light and traction light comes on it also disables the cruse control to the off position. Performance is totally reduced ! Vehicle shows active code C0020 for ABS pump motor control general electric failure..Diagnostic issued said to replace the hydraulic control unit. The problem was inspected by the Ram dealer and was reproduced by the tech and is currently being repaired by the Ram dealer. We were notified the complete unit was not available and only the possibility of the control motor was available at this time at a cost of $1400 give or take. When the cruise control kicks out in traffic you go from the posted speed limit to 0 if not caught immediately. Mileage 53,500

ABS braking Module and hydraulic control unit on this vehicle has been replaced under warrenty twice (in 2020 & 2022), vehicle now has 59K miles now and ABS has failed again, dash warnings are constant and cannot be turned off. Failed while driving from MO to FL last weekend

The ABS light and stabilizer light stay on along with the chime. It turns the cruise control off. The brake module/ABS/Hydraulic control unit is out and no parts and not going to be made per Ram dealers. This is a known issue with nothing done

ABS and Traction control lights illuminated at 38000 miles. Cruise control no longer functions either. Diagnostic scan indicates code C0020-01.

Abs light and traction control light continue to turn on and when they light up my cruise control stops working

Service electronic braking system and ABS light comes on and chimes repeatedly every time I drive the vehicle. This needs to be recalled as it is a chronic issue affecting thousands of trucks and owners.

Over the course of 30+ days the ABS indicator light would appear intermittently. We took our vehicle to a local mechanic. The code was run, and it was determined it was code number C0020-01 ABS PUMP MOTOR CONTROL ELECTRIC FAILURE, which recommended we replace the hydraulic control unit. The repair was not completed, and we contacted the local dealership to file and RO. It’s not a warranty repair. They suggested calling Chrysler directly who admitted lots of customers are calling for this issue; however, it’s not a recall repair at this point. This issue is causing failed ABS patterns during weather conditions or faults while the light is active. It’s a safety issue and could cause rollover on a vehicle that is already large and has higher potential for this issue.

Warning message and chimes indicating ABS service required. This is an indication the HCU is working incorrectly or failed which results in ABS brakes, cruise control, and 4x4 function loss. This is a known safety issue and should require a recall.

My 2018 Ram 2500 has Service Electronic Breaking System and Service Antilock break System, along with the traction control light coming on and off intermittently and will stay on for days the cut off and back on and off. I had a close call when a vehicle slammed on breaks in front of me (who knows why, it could have been a small child in the road) as I pressed the break pedal my breaks locked up and almost slid into the opposite lane. Thankfully the condition where dry and I had just put new tires on the truck. I took the truck to the Ram dealership in Jacksonville NC, and was told the ABS/HCU PUMP HAS INTERNAL FAULT AND PUMP MOTOR FAILURE. The part was on national backorder with no ETA and have been asking for updates for what seems like over a year and the same answer; under investigation and still on back order.... my family and I are on a nerve racking (due to dinging and flashing lights on the dash) road trip from GA to NE. I almost forgot to mention we are unable to use the cruise control functions due to the ABS/HCU/Traction control issues.. I understand there may be a class action lawsuit for this year make and model... What will it take to get an actual recall on these issues? Serious injuries, death? This should fall under the Lemon Law Act. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving the abs warning light will flash on then clear after a few seconds. It will do this several times while driving. Sometimes it will stay on for several minutes. When the warning is on the cruse control and exhaust brakes no longer work. It seems this may be a problem with the pump.

ABS Hydraulic Control Unit failed as it has done on millions of other rams. Yes I will keep the old part incase someone needs proof. Cruise control does not work. ABS and traction control also does not work posing all sorts of possibilities for accidents. Independent service center No but the manufacturer knows its an issue. The dealers can only order 1 unit every 7 days. Every dealer in the area is out of stock or has units on the shelf already assigned to other vehicles. Multiple Warning lights come and go on the dash as well as a ding to distract you. "service anti lock brake system" illuminates on the console.

Known issue that Ram 2500 from this year have issues with their ABS modules and hydraulic control unit (HCU) modules. This could potentially disable the electronic stability control (ESC), which is designed to help maintain vehicle control during a slide. The truck experiences issues such as the loss of anti-lock braking, cruise control, and traction control. This is a known issue that has been the subject of several class action lawsuits that Ram refuses to issue a recall for. Quoted price from dealer to fix is $1,200.

Abs light and traction control keep flashing codes on and off. I lose my abs abillities which is extremely dangerous my family. I am told by griffin motors in meadville PA that it is the HCU. They have no part available to fix.

ABS notification light and traction control light keep beeping.

ABS and Traction Control lights come on and go off constantly, while sitting still, when hitting a bump, and when in Park not moving. When the lights are on, ABS, Traction Control, and Cruise Control do not work. This is a serious safety issue.

2018 ram 2500, abs and traction control light came on and front driverside brake locked up cause me to lose control of the truck. Almost hit 2 other vehicles. Now there's a loud grinding noise and seems to be not drivable. Vehicle was towed to my local dealer this morning 7-29-24 (kendall jeep ram chrysler). Was told by a service advisor that I could possibly be a faulty abs module but they do not have any available diesel technicians available to diagnose at the moment. Might be serval days or weeks before they can troubleshoot.

On 07/02/2022 I had my Dodge Ram 2500 serviced and assessed for Electronic Braking System Warning and Service Soon light on, by Farlow Automotive 500 S. Wickham Road, West Melbourne, FL 32904 (321) 724-8888. The issue was diagnosed and identified as a bad ABS Control Module as well as a bad ABS Hydraulic Unit. The parts were ordered and installed on 07/20/2022. Following the installation the same Electronic Braking System Warning and Service Soon light went on again. I brought the truck back to Farlow Automotive immediately after the new braking units were installed and it was diagnosed as a faulty ABS Control Module and ABS Hydraulic Unit from the manufacturer. It has been over 2 years since the faulty ABS control module and ABS hydraulic unit has been installed and we have not received appropriate replacement to remedy this important braking system malfunction. We have experienced daily warning lights for 2 years plus, saying service Electronic Braking System. We tow an 8500 pound recreational vehicle for family outings that has repeatedly created significant concerns for the safety of myself and my family for the past 2 years. Farlow Automotive has informed me that they have been in contact with the manufacturer of the ABS Control Module and ABS Hydraulic Unit and that they continue to say it should be here soon but has not arrived after 2 years. For the safety of myself and my family as well as the safety of others driving on the highway, we have remained at risk of Electronic Breaking System failure for over 2 years, without any resolution.

The systems in question are the ABS and Traction Control Systems on my 2018 Ram 2500 6.7L 4x4 Heavy Duty. This vehicle has had issues from the beginning with these systems as the first repair took place at 10,640 miles at the dealership it was purchased from. This took care of the codes/lights for a short period and was covered under warranty but the same issue persisted not too long after mileage-wise. The next time this issue occurred was when the truck had 22,628 miles, the brake fluid was flushed in an attempt to correct the ABS light but was unsuccessful. The truck was then brought to another repair shop to correct the same issue again where the ABS Hydraulic Module, ABS Control Module, and the brake fluid were replaced at 23,702 miles at the sole cost of the owner. As of early July 2024, at 45,000 miles the lights have again started intermittently coming on stating there is an issue with both the ABS and Traction Control Systems and must be serviced. After reading through multiple forums and speaking to other owners, this seems to be a common occurrence and needs to be looked into by the NHTSA due to major safety concerns. Although there were no accidents or police reports in this case, this malfunction poses a major safety hazard for the driver, passengers, and others on the road if a recall is not issued. There should be no reason a $60,000+ heavy duty premium truck consistently has these issues with no accountability and/or repercussions held to the FCA group. My personal concern is for my family as this is our primary vehicle and living where we commonly have inclement weather, if the ABS and Traction Control Systems fail randomly during a storm, this has a high potential to cause major injury or death to both our family and other drivers on the road. Not to mention the potential cost of collision damage to the vehicle(s) and/or other person's property.

My 2018 Ram 2500 truck has a trailer break controller. I noticed that it may not be applying the breaks to my trailer properly. Then a few months later I get a warning on my dash that the ABS break system needs to be checked. I'm learning that ABS problems are connected with the trailer break controller. I'm also learning that this is a chronic problem with 2017 and 2018 Ram 2500 trucks. My truck has been in the shop twice for major problems with the ABS system since new. Once at 9,000 miles and at 35,000 miles, which it has now. My real complaint is that my truck was not breaking my trailer properly and it gave me no indication that it wasn't. There needs to be a recall on the ABS breaking system. The Ram dealer that did my repair even admitted to me that this was a chronic problem on these trucks. This is a safety issue that needs to be corrected. Thank You.

Intermittent ABS and Traction control light that after 2 weeks stayed on indefinitely due to the Hydraulic Control Unit that is known to go bad in these trucks. The dealer has replaced the HCU but at my own personal cost of around $900.00. This is something that has been a known issue on this truck and should be recalled as it poses a safety concern.

ABS FAILURE LIGHT & ALARMS WHEN DRIVING. THEN IT TURNS OFF THEN COMES BACK ON. THIS IS AN ANTI LOCK BREAKING SYSTEM FAILURE PER MESSAGE ON DASH. DURING ANY DRIVING SITUATION OR INCLEMENT WEATHER, THE ABS CAN FAIL WHEN NEEDED CAUSING AN ACCIDENT. THIS IS KNOWN ISSUE IN THE DODGE FORUMS AND RAM DEALERS ARE AWARE HOW COMMON IT IS. NHTSA NEEDS TO TELL DODGE TO RECALL THE PART PLEASE

ABS and Traction control warnings intermittently go off and sometimes stay on for a while. This causes the truck to not have abs and traction control. Had a bucking issues sliding down a boat ramp yesterday. Truck is under 40,000 miles. This is a well known issue for years now.

ABS Pump failure: First occurrence July 18 2022. Mileage 24268 ABS pump replace under warranty by dealership. Second occurrence: July 23 2024 Mileage 45907 ABS pump not replaced as of yet, parts out of warranty by one week. OEM warranty out by 25 months. I am the original owner and this vehicle has been gently used and not abused. The ABS pump failure, two occasions, of a part which should be have a life expectance of 100,000 miles, minimum.. Two failures at less than 50K miles in my mind is not acceptable, especially with a safety related part. From the research I have done, additionally talking with other owners and dealership technicians, this is a common problem especially with the 2017 - 2018 year model vehicles. Something should be done to rectify this issue.

Anti lock brake module repetitively fails. First one replaced 7/2021 with 51,xxx miles. Second failed 7/2024 with 69,000 miles. Loses ABS system, cruise control, electronics affect electronic throttle and stabilitrack.

"Service ABS" and "Traction control" warnings (and audible bell) coming on intermittently. Rough road surface doesn't cause it to happen more frequently, nor does speed of the vehicle (happens when still, in park, in drive, any speed). May happen several times in 30 minutes of driving, may not happen at all. I have not noticed a difference in braking or traction performance since this started.

The hydraulic control unit (HCU) and the anti-lock braking system (ABS) module, not sure which one. They will only work intermittently or not at all; this causes the warning lights/chime to come on/off or just stay on. During this action the vehicle has no ABS or traction control, this is the Third time my vehicle has needing this part serviced with out-of-pocket cost as well as wait times for the part to actually arrive at the dealership.

Service ABS and traction control warning keeps going off. Cruise control kicking off.

Service ABS warning and traction control lights constantly going off several times a minute, disappear for a few minutes, and then the cycle repeats. Have already replaced the ABS pump motor following code C0020-01 some years ago.

Wanted to report that my 2018 Ram 2(00 is experiencing the same abs/hcu issue that appears to be plaguing this year/model of Ram. I understand that tgis issue is still currently under investigation. Started with Beeping and traction control abs lights would come on and off intermittently. Now pretty much constantly on, unable to is cruise control.

Suddenly have service electronic braking system and service abs system lights flashing on and off while driving regardless of weather or road conditions. Truck has 97,074 miles on it and is out of warranty. Appears to be a common problem that needs to be addressed by NHTSA where as these components are essential to a safe vehicle

Truck has intermittent abs/esc light and warning for service electronic braking system, service abs system. Dealer has confirmed inactive codes and extended warranty will not cover unless they see active code. Being I live 1.5hrs front dealer and this is an intermittent light I have been unable to get it into the dealership while the lights are on and they're telling me the parts are on national backorder and they don't know when they can even get the parts

I have replaced the HPU 2x's and currently the ABS warning light comes on. I have a RAM case #86697757. This is going on for a year and the dealer says parts are unavailable for repair. The truck has 24,000 miles on it.

ABS lights flash on and off while driving constantly. Affects concentration and cruise control. Radio will randomly start pressing all over the screen changing settings and distracting the driver.

ON AND OFF SERVICE ABS AND TRACTION CONTROL INDICATORS.

Antilock brake warning light/chime and traction control warning light/chime keep going on and off causing the vehicle to have no antilock capabilities and disengaging the cruise control.

Abs system failed and had to brake hard causing the wheels to lock up and lose control of the truck ,lost speedometer, brake lights, 4x4,cc,trailer brakes

ABS warning light and electronic braking light will randomly come on and chime, not sure if this is going to affect braking.

General electrical failure of abs pump motor control. Intermittent issue causes loss of traction control, stability control and abs functions.

Several systems suddenly were disabled, ABS, Electronic Stability Control, Front & Rear Park sensors, Tire Monitor system as well as the cruise control that may not be considered safety. The truck only as 11K miles. I have not been able to reset the system and the noted systems are inactive. I will contact the dealership but am bracing for a less than supportive meeting. From what I've read this is a very common failure on this year and model truck

My 2018 Ram 2500 has 85,000 miles currently. At about 80,000 miles I got the ABS and Traction control warning lights along with dash messages to check the ABS amd electronic braking systems. I am a heavy equipment mechanic and thus checked the systems myself with a scan tool and other test equipment. I found that the ABS module has an internal electrical failure resulting in power not being supplied to the ABS pump/electric motor. I have verified that the pump works and has about a 48ohm resistance. If supplied with 12v and ground to the motor it will come on. Circuit testing from the electrical plug to the contacts for the motor one pin has contact and the other is an open circuit. I also have one seized plunger in the hydraulic control unit that is actuator by the motors eccentric lobe on the output shaft. After doing some research online I've found this is a very common issue on the 2017 and 2018 Ram heavy duty trucks, the 2500 and 3500 model specifically. I also found that neither the hydraulic control unit nor the ABS module have been available for purchase for a long time. I myself have been trying to order one for about 6 months. No dealer in my area can even give me an estimate time of availability. So currently I and many other have to drive a vehicle with a failed ABS system. This poses a greater risk of collision and unsafe braking. It is also a requirement to be working to pass a vehicle inspection so selling the vehicle or depending on state lived in you may not even be able to drive the vehicle at all.

Abs and traction disabled randomly while driving.

ABS and traction control warning lights coming in and out continuously while vehicle is on. Usually the lights will lock in after a while and then the ABS and Traction control will not function correctly. It is widespread with certain years of this vehicle and Ram refuses to admit a chronic problem.

July 11, 2024 Message alert appeared indash with instructions to service ABS system. This vehicle experienced the exact same issue in April of 2022 and was taken to the dealer(Patterson Dodge-Tyler,TX) for repair, where the ABS Module was replaced. The replacement was not covered by the warranty.

The service electronic brake system warning light and chime along with the traction control and ABS warning lights and the cruise control fails to work. This occurs frequently. The code is C0020-01 ABS (Anti-lock Braking System) Pump Motor ControlGeneral Electrical Failure I believe.

ABS light come on and the service antilock brake system light comes on and NO cruise control, happening all the time so NO ABS systems and in south dakota that is a big problem and no parts for 8 months now comes on when you hit a bump all the time 68 times driving 50 miles

Vehicles anti-lock brake, traction control systems become inoperable. Automaker is aware of the HCU and ABS defect, they have failed to recall affected vehicles or offer another remedy. Braking becomes much more difficult and a ram pickup becomes tougher to control without these systems, especially in dangerous road conditions caused by rain.

My ABS system has started going off and on intermittently but regularly. It turns my cruise control off and creates a hazardous situation with both traveling on interstate and when raining as I have no ABS.

Day after purchasing my used 2018 ram the abs light and traction control started dinging continuously. Brought back to dealer they say there is no fix at this time. Abs control module and hcu need changed/repair but there are no parts available for fix. So now I have to pay/drive for truck that brake system /traction control does not work properly. Please do a recall on the and make them fix!! There are so many specifically 2018 ram models that have this issue. When you could purchase the part it was $1000 fix and no guarantee how long it would last. I believe dealer knew this issue and cleared code before I arrived.

My ABS light sporadically comes on and off. Dealership says it is the HCU module. It was replaced under warranty in 2020 and now has failed again. Wanting to file report so it is noted to help with initiating a recall on this failing part. I have read that the ABS module has also had similars issues with no recall as of to date either.

ABS hydraulic pump failure, confirmed by Ram dealer. ABS light coming on and off affecting cruise control. Warning on dash says service ABS system. Truck only has 14350 miles No brake failures as of yet

Truck will flash warnings and dinging indicating that the anti-lock brakes and traction control has failed. Sometimes it'll stay that way and other times it will cycle multiple times. Like 20 times in a minute where the ABS and TCS are kicking on and off. Dangerous to have the brakes work like they're supposed to at random. It did this before in July of 2021, Scott Wood Dealership in Arkansas replaced the abs module/hcu. It is now doing it again, same symptoms.

My ABS system went out while under warranty. A couple years later now I'm getting ABS module warnings. Brakes are different and the cruise control is affected at times. Sounds like very common issue to certain Ram owners. We need a recall.

service abs system message and abs light and brake light coming on.. had checked and C0020-01 code for ABS pump motor control- general electrical failure

Vehicle is currently displaying ABS warning light. Current mileage is 45,327. Dealership previously replaced Hydraulic Control Unit (HCU) at 4,002 miles. ABS Module was not replaced as part was on back order. Dealer noted usual procedure is to replace HCU and ABS Module. Dealer noted code C0020-01 ABS Pump Motor Control - General Electrical Failure. At 24,923 miles, vehicle again displayed ABS Warning. Dealer found Code C0020-10 General ABS Pump Electrical Failure. Dealer replaced HCU. Dealer noted ABS warning is serious and vehicle should be repaired immediately. The safety of my family has been put at risk on multiple occasions. Problem has been confirmed and acknowledged by dealer. Problem has not been investigated by others.

Twice while going up a hill in the rain I was changing lanes and the cruise cut out causing the vehicle to slow down rapidly and kick out in the back. The cruise abruptly stops when the “service electronic braking system” and “service abs” lights and dinging come on. Apparently this also stops the traction control from working. Looking on the internet and forums, this is a very common issue. In fact, there is safety recalls on later model Rams with the same issue on the same parts. Why not the models that this started with?

HCU failed today 07/08/24. Service Electronic Brake System light comes on and off, traction control/abs malfunction indicator lights comes on and off constantly. Kicked cruise control off while traveling highway speeds causing a rapid deceleration to occur. Can't get in to dealership until July 17 to have it looked at. No other indicators/malfunction lights/codes came on prior to 07/08/24.

ABS and ECS warning indicators are continually coming on and going off. I have read many complaints on Ram forums that are identical to mine.

Everytime I press the brake pedal I am now receiving a "service electronic braking system." It is not every so often. It is every single time I press it. I have started researching this and there are thousands of other owners having the same problem that own the same truck as I do. They are also saying that every dealership either turns them away because they can't find the problem or they are giving conflicting reasons why it's happening and/or the part they say is the problem is on a massive, estensive backorder that could be months that sometimes fixes the problem for only a few months and have spent $1500 to $2500 depending on the location. They are also saying to report it to the NHTSA to make Ram fix the problem since it is so widespread across the nation.

C0020--01 ABS PUMP MOTOR CONTROL - GENERAL ELECTRIC FAILURE. Available for inspection. Safety of self and others is at risk in ABS brake failure. Independent service center has confirmed problem. Vehicle/component has not been inspected by mfg, police, insurance, or others (besides independent service center). Intermittent warning lamps and chimes began in June, 2024, approx 65k miles on the vehicle. My understanding is that this is a common issue, faulty component and also involves the Hydraulic Control Unit ("HCU"). These are expensive components and labor. Expense for repair/replacement should be covered by manufacturer.

The trucks warning lights indicated the ASB module, HCU module, and cruise control failed. The trailer brake controller, ABS system, and cruise control fail to function properly. The warning lamps and buzzer have been constantly going on and off for the last two years.

The truck's warning lights indicate ABS module, HCU module, and cruise control failure. The trailer brake controller, ASB system, and cruise control does not function. The truck's warning lights and chime have been going on and off for over 2 years.

Yes, I am on my second ABS brake module at 102,000 miles. The first one happened around 70,000 miles.

[XXX]. Location : somewhere in rural Pennsylvania. Incident ahead of me in heavy traffic. Applied brakes, more forcefully than usual. Immediately warning lights and audible alarm appeared on dash. “Service ABS system” . Was located in very rural area , no safe place to exit highway. At next exit , pulled off , brakes appeared to be functioning as normal. But dash warning lights proclaimed no ABS system and no traction control. Also lost function of cruise control and trailer brake control.. cautiously proceeded to destination. Relative had code reader - revealed code C0020-01 ABS Pump Motor Control. Investigation on internet revealed this is a very common problem among Ram 2500 trucks. Very expensive and not covered under warranty. I believe the NHTSA has received numerous reports from other Ram owners as to this problem. This situation is very unsafe with the loss of these very important safety features. Ram has refused to address this issue. I’m reporting this today in hopes that this agency dedicated to Safety will address this in a very timely manner.

Antilock braking system lights started coming on intermittently about 2 months ago. It would occur then stop for a few trips. It has progressed to a constant alert with a notice to have the ABS system serviced. The vehicle has less than 50,000 miles on it and is not used daily. It has been in the shop for over a week and they have not returned my calls as to the diagnosis. I have read that there have been alot of issues with this.

abs light and traction control light would come on intermittently while driving then stayed on causing cruise control to not work. been happening for over a year

Issue with the Hydraulic Control Unit. It requires replacing.

Traction control, electronic braking system and ABS warning lights flash and ding repeatedly with a warning message to service ABS system and Electronic braking system. Dealer and local shop cannot obtain parts. I need a safe truck for work.

Hi, The ABS System shows Service Antilock Brake System at the display, It comes and go so I assume that it is an intermittent issue, it does stays for hours or days and go on ad off during the whole drive, definitely is an issue. It allow the brakes to preventing locket when brake on certain circumstances. Had an issue on a wet pavement and have to handle to avoid crash with other vehicle cause the tires got locket and the truck slipped on the pavement for a considerable amount of feet's. Dealer inspected and replaced the module under warranty when I bought the truck and told me that it has to be replaced again.

Service ABS light on dash comes in every few seconds while driving. When this happens cruise control shuts off and ABS system does not work. The issue started happening with about 45,000 miles on the truck.

ABS light and traction control light comes on – says service electrical break system and antilock brake system

My ABS light keeps coming on and off intermittently causing my cruise control to be interrupted and causing vehicle to slow down unintended in traffic. doesn't stay on and only comes on and off when it feels like it. This is dangerous and could cause my brakes to not work properly or have someone hit me from behind when cruise control kicks off at high speeds on the highway. This should be recalled.

The anti-locking braking and traction control warning lights flicker along with a beeping. This causes the cruise control to also disengage. This first occurred when the 2018 truck was slightly over 3 years old and with 30,000 miles. I had both the HCU and ABS module replaced and it stopped the issue for a few years and 20,000 miles longer. At 50,500 miles, it has again become an issue.

HCU and ABS module brake failure causing the ABS and traction control warning lights and audible tone to intermittently go off. This also results in the cruise control failing to work. This is the second time of such occurrence. First at 3 years old and 30k miles and second at 6 years old and 50.5k miles.

ABS Hydraulic Control Unit intermittently malfunctioning while driving causing service ABS system warning to display and render ABS system along with Traction Control System and Stability Control inoperable. HCU electronic motor removed and internal inspection of brushes and motor components conducted. Inspection identified brushes sticking in guides causing intermittent contact with center shaft of motor. New HCU ordered 28 June 24.

Service ABS braking system keeps appearing intermittently along with traction control and ABS lights illuminating on instrument panel. NO RECALL for this problem has been issued and parts are expensive to replace. Please direct manufacturer to fix issue immediately. Thank you for your mission to ensure the safety of others!!

Second time my truck has thrown a code for the HCU being defective.

Abs and service electronic braking system warning lights continuously go on and off while driving truck

Have 47000 miles on truck and abs light kicks on and off. When it was checked code was abs general electrical failure.

I have had the ABS system failure happen for the third time. the first was around 24000 miles about May of 2020, repaired at a Ram dealer in New Mexico, I believe they only replaced the ABS ECU. The second time was 43,298 miles [XXX] 2022, they replaced the HCU AT Walker Ram in Alexandria Louisiana. It has now failed again with 65,723 miles on [XXX]. Every time it has cause the truck to lose the Anti-lock braking ability, traction control, cruse control & ETC. I feel that Ram should do a recall and fix the issue with a upgraded parts that doesn't fail every 20k so miles and cause a safety risk.

HCU for ABS has failed - Intermittently fails when in operation. Basically hit a bump in the road and it fails. Hit another bump and it "fixes itself". Then hit another bump and it fails. Lights up the ABS light, ESC light, brake light, esc. After some research, this seems to be a common issue on the 2018 Ram 2500's.

The Hydraulic Control Unit begins to malfunction presenting on the ECU as C0020-01 ABS Pump Motor Control-General Electrical Failure. This is fairly common in 4th generation 2500-3500 RAM trucks. The malfunction affects the ABS system, Traction Control system, and Adaptive Cruse Control system by deactivating them when the malfunction presents. This could cause the braking system and other systems to not perform in hard breaking/ emergency braking situations causing the operator to loose control of the vehicle. The Traction Control system and ABS system warning lights illuminate on the dash and the message of "service electronic braking system" is displayed on the HUD.

The abs control module has gone bad. When you take it to the dealership ship to get fixed they can’t order the replacement parts. The abs system is very important in heavy truck like these when it comes to drive on wet roads.The manufacturer should become responsible for making sure it get fixed and their is parts available to do so.

Antilock brake system control module failed causing loss of ABS.

ABS hydraulic control unit: Warning light and audible "ding" on the dashboard notes there is an issue with the ABS system. After taking this truck to several RAM service centers, the service tech says that it is part of a recall and that parts are not available. I cannot find any such recall, only a class action lawsuit. I haven't noticed a lack of breaking capabilities although I also have not engaged the breaks to the maximum which is where the ABS system would normally engage. Warnings are now constant while the truck is running.

Getting the same check engine warnings that many others are getting. Class action law suit going on in California.Ram says not covered by warranty

Intermittent ABS/cruise control failures and warnings. Disables trailer brakes while towing. Truck has 28k miles, has been repaired once already. Dealer says no recalls, and out of warranty. Subject of class action lawsuit?

Hydraulic cont module/ abs module is constantly going in and out causing the abs/traction control to be disabled and non functional cruise control. Highly unsafe when towing heavy like I do most of the time.

ABS/Electronic brake indicator light on continuous, no Dodge repair facility cannot seem to fix issue. This should be a recall item.

1. My truck is randomly throwing a C0020-01 code. 2. When the code is active the traction control and cruise control are disabled abruptly causing a safety concern. 3. Using scan tool I have verified that this code is active. Have contacted Mopar and they suggested replacing the ABS module and /or the HPU for the ABS. 4. No, only self diagnostics. 5. Fist happened on or around May 1st, 2024. Warning message on the heads up displays "C0020-01 Active, ABS PUMP MOTOR CONTROL-GENERAL ELECTRICAL FAILURE".

My ABS/TRACTION CONTROL Electrical warning is coming on and shuts my cruise off. When driving at highway speeds and towing, this has caused me to swerve some and come close to be rear ended. I had the system replaced at 48000 miles for the problem and it is doing it again at 103000 miles. I can tap on the electrical motor on the system and get another week of use without warnings

Vehicle keeps getting ABS control valve general power fault. Code scanned is C002001. Indications in vehicle are 1. Cruise control suddenly disengages if in use. 2. Instrument warnings of "ABS Control Failure" and "Electronic Braking System Failure" continue flashing for 10 seconds or sometimes constantly. Keeps happening to me on long trips away from home. Never locally. Gives the driver no idea if system is safe to drive or not. RAM forums on line are full of these complaints. I believe a recall is in order.

Intermittent ABS Light on slippery roads. C0020-01 Code found by dealership. Warranty does not cover failure.

2018 Ram 2500 diesel truck, ABS braking system was intermittent and now has stopped working all together affecting the cruise control and the ability to stop without locking up the brakes all together. This has started a couple of years ago and the dealer said everyone is having the problem and parts are hard to get.

The ABS Light is on and my ABS braking system on my 2018 RAM 2500 doesn't work. I drive on icy roads for at least 6 months out of the year. I need to have the ABS working on my vehicle so I can stop on icy or wet roads and not cause an accident. I scanned the code C0020-01(ABS Pump Motor Control - General Electrical Failure) using my Innova 6100P scan tool. The problem first occurred on [XXX]. RAM wants over $1,000 to replace the defective component. Dishman Dodge/Ram in Spokane, WA has confirmed this problem with their scan tool. My 2018 RAM 2500 is available for inspection upon request.

ABS Service light flashes on after rainy days and or going over a bumpy road.

Abs light comes on. Part is not available

While driving while it was raining earlier this year, the abs/ anti lock braking system service initiated on the dashboard. It now acitivates intermittenly. During my investigation into the issue I've found that this is a persistent problem with the Ram 2500 /2018 year model and newer and that there is a class action lawsuit that has been filed. I used a OBD11 reader and it threw a code ( C0020-01 )

ABS and Traction control light indicators on dash appeared intermittently. After diagnosing from the dealership, it is advised to changed the Antilock Brake System module. However, the dealership advised there is a block and that they must first change the Hydraulic control unit, although they say it is perfectly fine. While we have not had an accident (luckily) it appears there is an ongoing investigation and multiple lawsuits against Dodge/RAM/Chrysler for this systemic problem of faulty ABS on 2017-2018 Ram 2500/3500. My 2018 RAM 2500 only has 36,000 miles. This failure is premature and potentially very dangerous. The dealer could not advise whether my truck was safe to drive or not even if the indicator lights were off or on. I have not yet had the HCU replacement completed, however will have it completed next week. I am submitting this incident report as a pro-active report as this is a serious safety issue and one that is systemic across too many 2017-2018 Ram 2500. The manufacture is not allowing replacement of the ABS Module until the HCU is repaired which is an additional (Double) cost to the consumer.

The service electronic brake system light flashes intermittently, along with the traction control light and ABS light. Seems to occur when for no reason.

The ABS control module on my truck goes in and out from working to not working constantly dinging. Because of the ABS control module being defective it makes the traction control faulty as well which I have almost gotten in numerous car accidents at this point living in Florida with the rain and sliding all over the place. I have tried researching this and it is a huge problem with the 2018 RAM 2500 trucks. I have tried to reach out to dealerships and there is no solutions they just say that the part is on back order for months and there is nothing that can be done at this time due to the overwhelming demand with people experiencing the same issue.

The ABS light and traction control light comes on and off over and over again. When it is on, its seems to not work as well on slick surfaces. I have seen that there are numerous complaints of the same thing on these trucks. I have been told it is not under warranty by a dealer. Only 21,000 miles. I purchased the truck in 2019. I put a code reader on the truck and it came up with C0020-01. 1. ABS Pump Motor Control 2. Recirculation pump- General Electrical Failure. The truck is avalible for inspection.

The problem has been on going for past 15,000 miles. NOTE: Took vehicle to RAM Dealer in Kerrville Texas and they determined no problems despite dashboard messages and lights. Dealer states that they are NOT aware of ANY issues with ABS and Traction Control on any of the 2018 RAM 2500 vehicles.

Service anti-lock brakes and service eclectic brake message and lights for ABS and Traction control lights flash on and off at random time for no reason. When this happens the cruise control also stops working.

ABS and traction control lights come on intermittently. Cruise control won’t work when this happens. Problem seems to be a wiring issue and mainly happens during wet conditions and then stops after engine compartment warms up. I’m guessing ABS brake’s won’t function when light is on.

THERE IS A PROBLEM WITH THE ABS MODULE AND HYDRAULIC CONTROL UNIT. THIS TURNS THE ABS AND TRACTION CONTROL OFF. THIS IS A KNOWN ISSUE WITH SEVERAL COMPLAITS.

ABS light keeps going on and off. Had it repaired/replaced once under warranty, no longer under warranty. Nearly skid off the road on a rainy day when someone braked hard in front of me. This ABS issue is very dangerous. In my opinion, I shouldn't have to keep paying to repair this since it constantly fails.

We have been waiting on an improved HCU for the ABS system for approximately 18 months now to no avail. The ABS system is constantly failing and throwing codes related to the HCU and ABS module which shuts down the ABS system as well as cruise control and the dash lights up like a Christmas tree more times than I can count. My local dealership has no information on when parts will be available to fix this issue. The HCU has already been replaced once with the old stock unit and it has failed. This is unacceptable and a major safety concern since we are frequently hauling horses. Any information related to a fix would be greatly appreciated since RAM doesn’t seem to care at all.

The ABS module and HCU have failed for the second time. The first time they were replaced under warranty but now the truck is just outside of warranty and not covered and this is a 1600 dollar repair on a truck with 60k miles. The first time was approximately 30k miles. My safety is at risk when brake parts are malfunctioning and the problem has been confirmed by the dealership, and it's a very common issue without recall. Constant dinging happens while driving from alarms on the display stating to service abs and esc systems.

2018 RAM 2500 Laramie Longhorn Megacab. In November of 2023 the Service ABS dash light and constant dinging bell started going off. I use my truck to transport cattle and heavy equipment. I noticed I had NO ABS breaking and it was NOT safe to drive and tow. I took my truck to my mechanic - after analysis on his computer I was told the ABS Module and the HCU both were bad and needed replacement. My mechanic attempted to order parts and was told that there the HCU was available but the ABS was backordered with NO KNOWN AVAILABLITY DATE. I contacted three dealers .... told the same thing ... also was told to drive the truck and tow ...very unsafe!!!! RECALL!!!!!

In March I started experiencing an intermittent ABS warning light. When this light is active the truck is without anti-lock braking and traction control (as well as cruise control), which are critical safety features. This is the second time that I have had this problem on this truck with the same module. In both cases I had the dealership make the needed repairs. The first instance was repaired under warranty on 11/06/2020 at 24,433 miles. The most recent instance was repaired on 3/27/2024 at 44,181 miles and at a cost of $798.15. These two failures indicate a service life of less than 25,000 miles for a critical piece of safety equipment. The attached dealership repair invoices show that it was the exact same part that was replaced. At the time of the most recent issue, I contacted Ram Customer Care by phone and after several calls back and forth they declined to provide warranty cost assistance. However, they indicated that they had contacted the dealership, but incorrectly reported back to me the cause of the fault. I pointed out that they were making a determination on apparently incorrect information. When they declined the second time I requested that they put that in an email, which is attached. Given that there has already been a recall on later model years for this exact problem, and that there appears to be a substantial number of similar claims from 2017-2018 model years owners, I would like to add my experience (and expense) to whatever other complaints that you have received and encourage a recall for this issue on these model year Rams in order to save lives that could result from a system failure during a critical incident.

ABS and traction lights have started staying on and when on the cruise system does not work

My 2018 Ram 2500 threw and ABS warning lamp and code C0020-01, which was confirmed by Key Chrysler Dodge Jeep Ram of Rochester, NH on [XXX]. I lost brake performance on my drivers side.

Abs and traction control have intermittent failure resulting in instability and collision.

The ABS system in my truck has failed 2 times in the past 2 years. The ABS module failed at 36,000 miles was replaced in fall 2021 with a "updated" AB part number. Less than 2 years later in the fall of 2023 the ABS failed again at 60,000 miles. At this time I was told that the replacement parts were not available until march 2024. Parts availability has been pushed back and I have no idea when they will become available. I am left with a vehicle that has no function ABS system, stability control or cruise control.

Currently are having to replace the ABS component, AGAIN. Already replaced it once. First time was about 2.5 years ago. I have a receipt, but unable to download at this time. Truck was dropped off yesterday at mechanic shop for same issue. (05-14-24)

For the second time since the vehicle's purchase in 2019, the Antilock Braking System is flashing an intermittent error stating that the Antilock Braking System needs to be serviced. When the system flashes the error, the antilock brakes, cruise control, and stability control become disabled. The error sometimes will clear itself, and then immediately return a minute or two later. Three years ago I had this same issue repaired once before under the vehicle warranty. At that time, I was told the Hydraulic Control Unit for the ABS system had failed. Now, without warning or reason the system is failing once again and RAM refuses to replace this defective part. Through an online investigation, I have discovered that thousands of Ram owners are experiencing the same defective part and circumstances. Without proper functioning brakes, antilocking brakes and stability control, the vehicle cannot be driven without great risk to the vehicle's operator and occupants, and additionally other motorists.

My service ABS brake like comes on and off intermittently. When it does I can't use cruise control. We are on vacation and have called to RAM dealers and none has time to look at the truck. I looked on the internet and found that there are literally thousands of people complaining about this. Apparentluy RAM recalled the 2019's for this issue, but nothing before. This is not the first issue that we've had with the ABS brakes on this truck. It has me concerned since I pull and 8000-lb travel trialer.

ABS light and “Service ABS system” message pops up intermittently.

ABS system went out in my truck, according to the internet you have getting LOTS of complaints about this issue, anything happening?

The ABS and Traction Control lights come on and off intermittently. It’s a known issue that can cause complete loss of breaks. It’s linked to the 2017 and 2018 Ram trucks and is all over the internet as being a problem. It’s a safety issue and needs to be taken care of immediately before someone dies or kills someone else because of an issue Dodge Ram has known about since 17-18.

ABS, traction control, cruise control, 4WD works intermittently ABS and traction control warning flash, wile ABS light is on you can not use traction control ABS system does not engage and cruise control is inoperable. Seen by dealer (benson CDJR) in April and June of 2023 and parts to repair were NOT available. Being seen again as new part is currently available to be repaired 4/6/24. After 1 year of not being able to find a solution for the problem. I have slid on sharp turns, got stuck wile pulling camper due to no 4wd among other issues. Contacted RAM regarding replacement assistance and they denied due to after market warranty. I am still responsible for 250$ for a repair that should have been a recall for Sevier safety concerns by RAM

The service electronic brake control and ABS light keeps flashing and the warning bell keeps going off every time I drive it, It only has 22k miles on the truck. There should be a recall for this as thousands of 2017 - 2018 ram trucks have this problem. Plus its dangerous driving like that.

Service Electronic Braking System error message repeatedly and randomly started coming on and chiming beginning in December 2023. Have tried to get a new ABS Pump and Module to no avail since parts are not available.

The ABS / HCU ELECTRICAL BRAKE SYSTEM HAS THE SENORS BLINGING AND WANT STOP. Done had this truck in the shop 4 times fir this same problem it quits and starts back but now its on all the time.

Service Electronic Braking System warning lights random comes on and off every time you drive it.

ABS and Traction light on dash. Chiming of alarm. This alarm turns off cruise control and feels like it applies the brakes at 70 mph. Lots of brake dust accumulating on my rims. It happens some days but not every day. Some days there is a constant alarm chime and cruise won't activate. On 10/24/23, parts weren't scheduled to be released until February 2024. Charged over $100 diagnostic fee for the ABS, traction control lights on the dash. By looking at other reports, this has been an issue for several years. They have known for over 2 years that there is an issue. Why is it taking so long to get a fix in place? ABS is a safety system. This should be a recall. The recall should cover replacing the brake pads and rotors also.

For 8 Months, I have had the ABS, Traction Control, and Service Electronic Braking System Lights/Messages illuminated, with endless warning chimes while driving. Anchorage Chrysler has had the truck in 4 separate times - finally troubleshooting the issue to a defective ABS/HCU component on [XXX]. I was told that replacement parts would be available by July 2024. On [XXX] I called to check on the parts. I was told that all ordered parts for this issue are blocked. Now, they want me to bring in the truck again so that technicians can verify “Step 6” pass/fail. At that point, a part could be ordered. This problem started in Sep 2023, and I drove this truck all winter in Alaska without anti-lock brakes. The brakes operate like vehicles without ABS, and will lock up if depressed too hard. There is a class action lawsuit concerning this problem out of California, but they wouldn’t let me join due to my living in Alaska. This should be a safety recall. I have been told 4 different stories on how this will be fixed over the past 8 months. Every time I check on the status of my parts - they have come up with other things to check before parts will be released. I have a 2018 Ram 2500, purchased new in 2019 and have 25,000 miles on this vehicle. I have been more than patient. When new directives come out, the dealership doesn’t even contact the customers that are waiting on parts. Like I stated earlier, I called to check on my ABS/HCU that was supposed to be available NLT July 2024, and that’s when I was notified I needed to schedule another appointment so they can verify the results of “Step 6” before parts will be released. They should have contacted all customers with these issues as soon as the message came out - but they didn’t. They wait for you to call and check the status, and then give you the news that it requires more troubleshooting. This is totally unacceptable. How much worse does a problem have to be before a recall is issued? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

While driving, ABS system warning lights illuminated accompanied by intermittent alarm. ABS System Failure confirmed by selling dealer, further confirmed via Fiat Chrysler Automobile (FCA) TSB notice "C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE." This TSB particularly confirms/advises both the HCU and the ABS be serviced / replaced. The original pump motor is no longer available and per dealer is being re-engineered due to defect. This failure is a significant risk to the vehicle operator, passengers, and the general public and should be remedied immediately at the manufacturer's expense via NHTSA / FCA initiated recall.

Had a deer run out in front of me on the road. When i hit the brakes the truck didn't stop as fast and pulled to the rt really hard making me go into the ditch. The service abs light is constantly goin on and off before that and is still doin the same now. Scan tool says abs hcu module. I have my son driving this truck at times as well and it is not safe. There are thousands of the same trucks with the same issues i found out now. NEEDS TO BE RECALLED

Service electronic braking system / ABS service antilock brake system. Both these lights come on and ding, half a second later they are off. This happens non stop, looks like everyone is having this problem. This should be a recall not a $1200 fix. I only have 58,252 miles on my truck. This problem for me has been going on and off for 2 months.

ABS light came on several months ago. Trusted local diesel mechanic tells us it's a common problem with 2018 RAM trucks and it will cost minimum $2000.00-$4000.00 to fix. A visit to the local RAM dealership in January 2024 advised us that RAM will not have the part available until at least June 2024 and that the fix would 100% be our cost and not covered by any kind of warranty.

It has been over a year since my truck has had the ABS light and traction control lights on. My repair shop has stated that the problem is the ABS pump. However, the part has been sold out for a year now. So I have been forced to drive my vehicle without ABS breaks for over a year.

2018 Ram 2500 ABS control module and hydraulic control unit is defective. The vehicle’s information system illuminates service antilock brake system and service electrical braking system repeatedly during normal driving conditions.This is a known issue that Ram/Mopar has yet put out a recall on this defective part. I have contacted a local dealership and was told many times the part is on back order. I do not feel comfortable driving this vehicle knowing it has a defective part that could prevent a possible accident.

ABS Module/HCU failure. I’ve gotten this intermittently since I’ve owned the truck. However, it seems I’ve had a total failure now. I’ve had the ABS light on for 1 continuous month now resulting in loss of ABS braking and cruise control. A 7500 pound truck without ABS is very dangerous.

"Service Electronic Braking System" and "Service Antilock Braking System" Braking system is failing and not safe to drive. When the CEL is active, my anti-lock brakes do not work, I've almost been involved in multiple crashes as the ABS will not engage and the brakes will lock and cause the vehicle to slide or become incontrollable. This has been reported by a large group of owners and no resolution has been implemented and a replacement part is not available.

In April , 2020, I contacted the RAM dealership because the "Service Electronic Braking System" warning light was coming on intermittently in my truck. It took two months to get an appointment scheduled at which time the truck was diagnosed with a faulty ABS hydraulic module. Estimated delivery time for the replacement part was an additional two months which made the truck over the 36000 mile warranty period. An appointment was made to have the part replaced but when I took the vehicle in I was advised there was no mechanic available to do the work. I purchased the part and had it installed by another dealer at a total cost of $986.86. The exact same problem reoccurred in May, 2022 and the part was replaced at a cost of $882.01. The problem reoccurred again in April, 2023 and was misdiagnosed as a computer problem which was repaired at a cost of $722.80. A new hydraulic module was then ordered to actually fix the problem and here it is a year later and there is still no firm delivery date available. The alarm and warning light flash almost constantly. We have had three close calls in the rain due to the failure of the ABS system and at this point I feel the vehicle is unsafe to drive. In addition to the ABS system malfunctioning, this problem also makes the cruise control inoperable. Recently the right front brake has begun to chatter making the vehicle pull to the right.

My brakes went out in November 2020 with a bad hydraulic brake control and hydraulic control unit. The parts were replaced and everything was fine until December 2023. The same alarm came up that the truck brakes had failed. I took the truck back to the dealer who fixed it. They notified me that there is a known problem with these parts and there are no parts available. They ordered the parts for me, it is now April 22, 2024, and they still say there are no parts available. I also had contacted another dealer who stated the same situation, there are no parts available, and that the brake issues are an ongoing problem that Dodge is not taking care of. My truck is unsafe, there are tens of thousands of these trucks that are unsafe. The manufacturer should be made to correct the problems and fix the trucks.

ABS. Code c0020-01 abs pump motor failure

The ABS pump motor control circuit has an electrical failure. The truck's safety is at risk of incident without the help of the ABS system. The problem is persistent as the ABS warning lamp and Service Electronic Brake System message pops up every time the brake is applied. The dealership recommends the part be replaced.

I have a total loss of ABS, traction control, and cruise control.

Service abs lights flash then go away no abs functioning intermittent

The ABS control module is not working. This turns off the anti-lock brakes and I have nearly hit someone when the brakes locked and skid across the intersection. The consistency beeping and vehicle message block the information screen. I have been waiting for over a year for the parts to be replaced. It is a shame that new vehicles safety systems doesn't work. The part is 68347098AA the replacement 68347098AB or 68347098AC is not available.

Had this issue before keep getting service electronic braking system and service abs system messages. Like I said I had this very issue about a year or two ago it was repaired by ram but was covered under warranty. Fast forward a year or two having same issue again maybe 10,000 miles later.

ABS module quit working in May 2023. I can’t get a replacement as Ram claims they are coming but they are not. I pull a travel trailer and it’s a safety concern with no solution in the works

Hitting bump or random moments (intermittent). The ABS module comes up with code C0020-01 for ABS Pump Module General Electrical Fault. Truck loses ABS, Traction Control, as well as Cruise Control. Vehicles Odo is 7284 miles.

ON 3/21/2024 while traveling HCU/ABS Control module failed prompting intermittent dash lights and disabling ABS/TCS and Cruise Control. This was the first time this occurred and came without warning creating a very dangerous situation. As a result, hile traveling down the interstate during a rain event the truck lost traction at high speed (65mph in 70mph zone). This was instantaneous under medium throttle when the ABS/HCU ABS module suddenly disengaged allowing wheel spin on wet pavement. This caused the truck to briefly turn sideways on the freeway until intervened by myself the driver. This could have been very dangerous as there were numerous other vehicles in lanes on either side. No collision resulted. The vehicle has good tires and is in good condition outside of this failure. Upon investigation, I have found this to be very common on these trucks yrs 17-18. When I called the manufacturer they stated they are back ordered as it is a common failure and frequently require replacement.

ABS and traction control lights going off and on. Stating abs need serviced. Took to a auto maintenance and told it need anew pump and module would not be available until August 24,2024. In January 2021hydraulic unit was replaced now need to replace it again

Within the first 20k miles of owning this truck the check electronic power steering came on and the abs module was replaced. Now at 60k miles it's happening again from some basic research it seems that 2018 rams all suffer from this faulty part and even when it's replaced it still didn't last and the part it now backordered. ABS is a major part of the safety of a truck even more so when it's a heavy 2500. Ram needs to step up and take care of its customers and replace these units in a recall.

Abs comes and goes most of the time it doesn’t work had the issue for over a year when it’s not working no cruise control. I had rydell deal ship look at it and said it’s either the module or the pump.

ABS and Electronic braking system lights come on and off. No codes. Reading about it and there are thousands of cases across the US. Something has to be done. Definitely a safety issue.

Abs turns off and on by itself due to faulty abs system causing the truck to lose all abs and traction control features

Service electronic braking system Notification and ding won’t stop going off. Truck has less than 50k and through my research this is a common issue with this truck. I don’t want to drive it anymore fit safety reasons. Bought the truck 2 months ago and have had an issue since I purchased it

ABS and traction control lights coming on intermittently. I tow a camper with this and understand this is a known problem which is continuing to happen without any successful resolution.

I have intermittent Service Electronic Braking System and Service Antilock Brake System warning light. It started about 1 year ago at about 72000 miles. The diagnostic tool lists a C002001 fault (ABS Pump Motor Control General Electrical Failure. When the fault is active, I have no Antilock Brake, no cruise control and no traction control. I have no taken the problem to the dealership due to initial cost of diagnostics that they charge. Parts and labor are not covered under warranty.

Abs and traction control light come on. Then off. Some days every 5 minutes. Some days once a day. Alarms sound. ABS and cruise control won’t work. Dealer reported over 10k truck have issue. Parts are on backorder for 6 months. I was told july 2024 for part. There should be a recall. So many trucks with same problem.

Started experiencing the ABS and Traction Control lights coming on, sometimes momentarily and very intermittently, sometimes (but less frequently) coming on for long periods of time. The frequency of these events has been increasing. A scan of the vehicle indicates I am receiving these this code... C0020-01 - ABS Pump Motor Control - General Electrical Failure This seems to be a very common complaint on my truck's make, model, and year. The result is I lose cruise control functionality, four-wheel drive, and seemingly the use of anti-lock breaks and traction control. It is very irritating as the warning lights and alarms often go on-off many times a minute, often going on for hours.

ABS light and traction control light illuminated on dash. Service both comes up on info screen. Wheels will skid when braking in wet weather, rain, snow and or ice. Will lose traction when departing from a stop in wet weather, or starting from a stop on a hill. Safety of myself and any or all occupants (wife,grandkids,friends) including other vehicles and their occupants around me whenever this truck is operated. Problem has been reproduced warning lights have been on constantly for over one year and are on still today. Refuse to take it to the dealer due to the fact I have to pay for diagnostics on a safety issue they refuse to recognize as a problem, and then they want to charge me over 1K to fix with no guarantee of solving the problem. Warning lamps are on chimes from dash Lights came on 8/1/2023 and remain on to this day.

I bought a 2018 ram 2500 last year and ever since driving it off the lot the abs light constantly turns off and on and recently the abs modulator has completely failed at 115,000 miles. It affects the cruise control and braising ability of the vehicle and I cannot use the truck properly or safely due to the constant abs issues.

The ABS system begins to fault and flash warnings intermittently while driving down the highway or any road. This could cause the ABS system to fail on an event it is needed to avoid a crash or object in the roadway. Research on the internet shows this is a common issue with this year and model and there is a class action suit for it.

Intermittent alerts related to service ABS light on the dash along with Traction Control light. Seems to disable ABS when the fault light comes on, also disables cruise control during driving when the service alerts flash on the dash. Constant beeping of the alert is a major distraction. Truck has 26,000 miles in it. Dealership said ABS module and HCU need to be replaced but parts are on back order until August but are not positive when parts will be available. Why is this not a recall?

The ABS and anti skid lights on the dash come on and off sporadically. The pump and module have been replaced. The problem did not occur for awhile. Now it has started over again. It seems harder to brake since the problem has started.

The HCM for the ABS system has failed at about 50K miles. I took it to the dealer and they replaced the HCM for $850 and it worked for about 25 miles and the ABS light came on again. I took it back to the dealer and they said it must be a bad module and they are on back order and would let me know when they get one. That was about 3 months ago and I still haven't heard from them. I know this has happened with a lot of other Rams and they need to have a recall for it. When it goes out the cruise control also stops working. If I have to make a sudden stop on a wet road, my brakes will lock, endangering myself and others.

Service abs ABS traction control dash lights on and off

The ABS Service Antilock Brake System messages comes on intermittently and chimes every 2-3 seconds. Some days the message and chime does not come on, but it is usually the day after the truck has been turned off for a period of time. The issue started on 16 March 2024, I still have the issue today, and it happens at any speed. After doing some research, I found that many of the same year and model truck has had the issue, and it seems to be the Antilock brake module Electronic Control Unit and or Hydraulic Control Unit. I contacted the dealership to see if I can get the issue repaired under my extended warranty, but the part is on back order. The vehicle is available for inspection, but I haven't had a chance to take it to the dealership as of yet.

ABS and Traction Control warning light always on.

Starting at about 28,000 miles the ABS & Traction Control lights would come on, Disabling the Anti-lock braking system. During slick road conditions the truck would often skid when braking, especially when towing. The anti-lock brakes didn't work. This also triggered the check Engine light, Disabling the Cruise Control. All of this would occur randomly and often with no pattern. Prior to reaching 36,000 miles on the odometer, I went to Andy Mohr Chrysler Dodge Jeep for diagnostics. Service Department reported a code for internal ABS Module Failure. I then returned to the Dealership at 39,249 miles on [XXX] for recall on drag link replacement in steering and for repair of traction control system. Steering system was repaired but parts were on national back-order for ABS Repair. They delivered truck on [XXX] but kept repair order open with no charge at that time. Received call from dealership saying parts had arrived for ABS system for repair on [XXX]. Repairs were completed and I picked truck up on [XXX]. The invoice total was $1862.27, as they had charged for the steering recall also. After a month of back and forth with the service department and then speaking to the General Manager, they refunded $187.31 on 3/4/2024 meaning the ABS repair was $1674.96. I'm still unsure if that is the correct amount. Repair order # [XXX]. Truck is now working properly when braking.

Our antisocial brake modele has been out since November 2023.The light keeps coming on. We had it checked with a diagnostic check twice and it was confirmed. The dealer cannot get the part and we have tried to escalate the problem through Chrysler, they refuse to do so. The mechanics can not tell us it is safe to drive so we are barely driving the truck. We are afraid we won't have brakes and if we are in an accident, it wouldn't be covered . They can't get the part and told us that they had more than 4,000 on backorder from our dealership. This is not covered and we have to pay over 450.00 just for the part and they can't even get it in.

ABS / Traction control disabled dash lights flashing.

When taking off initially with the truck sometimes within the first 30 seconds of moving there is two yellow lights that come on the dash, while the center text window displays service brake system. The stored MIL code is C0020-01. Also when going over bumps in the road the message will also return. Sometimes it stays on, and I do not have the ability to use cruise control. One time I was driving on the freeway and the surface was wet, as it had been raining. I needed to slow down rapidly because there was a sudden change in traffic. I went to hit the brakes and the truck had locked up the wheels, and then after the same lights and text were displayed.

Abs & traction control lights come on and off constantly. Cruise control will not work when lights are on. They stay on 95% of the time. Told this is an abs pump failure issue

While driving a electric braking system message was displayed. Also an ABS and traction control warning lights came on. After driving the front disc brakes did not release, causing them to overheat. The vehicle only has 2,666 miles on it.

Hydraulic Control Unit failed, along with the control module per dealer diagnostics. The ABS warning and traction control light is flashing consistently, and the ABS system is not working. The dealer has indicated there is no estimate on when these parts will be available. This is the third occurrence of the same bad components.

Hydraulic brake system not working abs traction control no cruise. Dealer stated parts not available and not sure when

Message " service electronic braking system" keeps appearing on dash. The truck has less than 18000 miles, never off road or in snow/salt.. Garage kept. No accidents ever. I'm very concerned about the safety of the vehicle . I haven't taken it to the dealer yet, I hear parts are not available, and its a common failure on the 2017-2018 ram trucks

The abs light and traction control light comes on intermittently which is caused by the HCU. Could cause a wreck

On January 15, 2024 my 2018 RAM 2500 truck with 6.7 Cummins Diesel engine was towed to dealer after "Service Antilock Braking Systems" warnings were displayed on dash instruments. Dealer diagnosed that the anti-lock brake module needed replacement but part is back-ordered with no estimate on expected replacement date. Was told by dealer there will be no harm to vehicle mechanical/electrical systems driving truck as is without anti-lock brakes other than possible lack of traction if driving on snow/ice, etc. As of 3/22/24, latest dealer update is an upcoming 4/1/24 update from RAM Corporate unit with no information on what to expect as yet. Not encouraging when faced with mountain driving pulling heavy trailer this summer and no anti-lock braking active. Audible & Visual warnings still displaying and dinging daily at this time.

Hydraulic Control Unit failed, along with the control module. The ABS warning light is flashing intermittently, and i do no believe the ABS system is working. The dealer has indicated there is no estimate on when these parts will be available.

Hello, I have a 2018 Ram 2500 with 35,000 miles, there is a well-known issue regarding the anti-Lock Braking Systems which effects 2017 and 2018 models which, Stellantis -RAM refuses to address. My truck suffers from this issue, the ABS and traction control warning lights constantly flicker on and off and there is an audible ding when this occurs. My local dealer diagnosed the problem, and the truck needs to have the HCU and ABS modules replaced. The cost to perform this work is nearly $2,000 since the parts are expensive and there is a fair amount of programming which needs to occur. Besides the cost the main issue is that the parts are not even available. I have been waiting on the parts since November 2023, my dealer says the next "production" date for the part is late June. I received this same type of response 2 times already, first for November, then February now June. Last I checked there are over 400 requests for these parts before me. At this point I drive an unsafe vehicle with no ABS or traction control, and I can’t even get it repaired . I also can’t use the truck for its intended purpose of towing. I’m looking for some assistance in this matter. There is also an active Class action lawsuit against Stellantis to provide relief for owners of these trucks, myself being one. [XXX] Thank you for your consideration, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The ABS/EBS errors lights comes on and cruise control won't work. Did some research online seems like a common problem. Hoping to see a recall by Ram.

The electronic braking system failure alert is frequently happening. I believe this includes a failure in the anti-lock braking system also. If cruise control is active, it is also disabled.

The anti-lock braking system, traction control and speed control system continue to flash on and off. While driving here in Huntsville, Alabama it snowed and my braking system failed causing me to nearly crash.

Abs light and traction control lights went off causing the truck to throw C0020-01 error. Dealer suggested replacing HCU and ABS MODULE

My 2018 RAM 2500 has 30,176 miles on it. Two years ago the HCU and module controlling the ABS system failed and was replaced. When the system fails numerous lights and warning chimes activate and the cruise control stops working. The system has failed again and the dealer tells me it will take 45+ days to get the parts necessary to repair the ABS system. After researching online I discovered an open class action lawsuit against FCA for this problem. I also discovered that this is a common problem with 2500 and 3500 RAM trucks after reading owner forum sites but so far no recall has been issued by NTHSA. This is a major safety issue for owners and needs to be fixed.

The ABS controller on my truck has gone out for the second time. where do i take it to get RAM to fix this issue this? i paid out of pocket for this repair the first time. please advise.

Loss of ABS/traction control. Electrical failure ABS pump motor. Loss of braking ability. Vehicle has very low mileage, less the 3,000 miles.

Abs warning and abs in operational

The ABS control module and the Hydraulic control unit are both faulty and need to be replaced. Parts are not available to fix this issue. Recently the truck's brakes have started randomly applying themselves so hard that it slows the truck down even while accelerating. I find this very unsafe.

Abs pump motor, hcu and module need to be replaced. Dodge knows this is a problem and they need to stand behind their product and recall these vehicles. The cruise control cannot be used, it surges trying to slow the vehicle down due to the faulty modules. The parts are on back order until June. This issue started at 46,000 miles but because the vehicle is over 5 years old Dodge doesn’t want to cover the repair. Not a happy customer! Please recall these vehicles.

A warning light appears and anti-lock brakes do not function. this is the second time for this same defect. The first time was as approximatley 40000 miles and now jusd past 80000 miles. The parts for repair are unavailable thru dealer and they said it probably be December before they got parts in. I now have no anit-lock brakes and no cruise control. It seems the cruise control circuit is with the anti-lock brakes circuit. This seems to me to be a real safety issure with all of these Ram 2500 trucks. The dealer knows all about it but cannot help.

My truck had warning lights come on in December 2023 saying to service the anti-lock braking system and the electronic brakes. I took it to a mechanic and I was told that the part would take at least 45 days to get. Now we're being told it will take 3 months to get because it is impossible to find. After researching this online, it is a nationwide problem for many Dodge Ram owners. These vehicles are out on the road needing this part to keep their brake systems from failing and it is impossible to get.

The ABS (anti-lock braking system) and EBS (electronic braking system) failed in the fall of 2023. I was told by the dealer that a new part could be ordered on 21-FEB-24. On 21-FEB-24, a new bulletin was released that indicated a new part could be ordered in JUN-24. This is ridiculous. When are you guys going to do something? How many near accidents, near accidents, etc. is required for you guys to rain on the Stellantis parade? These trucks are dangerous and they have been out of reliable service going on a year. Are you going to force Stellantis to compensate owners for the loss of their truck for close to a year or do you view this as BAU? I have to say I am completely disgusted by the apparent inability of Stellantis to properly resolve this issue. I am also disgusted that you guys have done nothing.

I brought my 2018 Ram 2500 to the dealership for the ABS light. I was told i needed to replace the ABS HCU and the ABS module and that old of the parts is not available to order until June 2024 Maybe. I am unable to get the truck inspected do to this issue.

The ABS service light keeps coming on and beeping. It will go off after a little while but then returns intermittantly while driving. Apparently this is a known problem and should be a recall. Many owners are wasting thousands of dollars for repairs that should be covered by a recall.

The component or system that is failing or malfunction is the ABS Hydraulic Control Unit (HCU) and ABS module. The malfunction is turning off my ABS and TCS system, making the vehicle unsafe to drive. Also the ABS and TCS dash lights are constantly dinging and going off and on distracting me while I'm driving. This issue is well know with the dealer. Here is a TBS from 2020: RAM TSB S2005000004 The vehicle has been inspected and and the ABS module was already replaced, but didn't fix the issue. This has been happening since I bought the truck.

ABS MODULE AND HYDRAULIC CONTROL UNIT ON A 2018 RAM 2500,HAVE REPLACED IT TWICE,ITS OUT AGAIN ,AND OUT OF WARRANTY.52K

My truck has right at 80,000 miles. Every so often I get two dash lights. One is ABS service and anti skid warning. They randomly show up. They pop up very quickly then go away. But it happens non stop. I have done some research and it seems that there is thousands of people with the same truck and year model with this same issue. I went to the dealer in Seguin, Tx and they told me that there was really nothing I could do to fix the issue, unless I wanted to wait eight months. But the new part rarely last. They flat out told me to not follow any one too close because hard braking could fail without anti skid working properly. RAM needs to make this right. I can’t believe that there has been this many people complain about a serious safety concern and nothing has been done.

My ABS light has started to flash off and on and states that I need to ring it in for service. my truck has just under 38k miles and when I first bought my truck I had to have the master cylinder replaced. The dealer quoted 1200 dollars to fix the ABS issue by replacing the HCU, and stated they are the only ones that can complete the repair. I see there there is a service bulletin related to this issue and when looking online this appears to be a large widespread issue.

For over a year and a half I have been without my ABS system due to FCA installing faulty ABS modules and hydraulic units in the 2017-2018 Ram 2500's and 3500's. The same units were installed in the 2019-2021 Ram 2500, 3500 but FCA recalled those models. I am also without cruise control as well. FCA has even put out a technical service bulletin about this and still has not resolved this issue.

I keep getting an Electronic Brake Service message and ABS message that randomly starts dinging and popping up on my display that also disables my cruise control. This obviously is a known issue and I would like to know what is being done to correct this. I have read several and seen over 3000 reports of this problem so why is it not being addressed to make our vehicles safer when it is a known fault. We travel with our camper and travel baseball all summer long and this is not acceptable when it comes to my family or the safety of others on the road around me.

ABS light is on and the ABS Controller has already been changed out twice. Its unsafe braking conditions for myself and the public especially in poor weather conditions or towing.

My 2018 RAM 2500 pickup displays these messages "Service Electronic Braking System" and "Service ABS Braking System". The cruise control and the Electronic stabilization system stop working when the messages displays. I am afraid to drive the truck as no ABS or electronic braking makes the truck unsafe to dive. The dealer says the HCU needs to be replaced but the replacement is being redesigned and is not ready. The truck has been parked for over a year. Why hasn't there been a recall on this issue? The truck is unsafe to drive.

The ABS module and Hydraulic control unit are faulty causing an intermittent activation of the ABS warning light and Electronic Braking warning lights. When the lights come on the cruise control will disengage, if set, and cannot be reset until the light goes out. The length of time the lights stay on vary from a few seconds to a few hours, to always on. When in park the light can be made to go off if the brake pedal is pressed excessively hard. There is an ABS error code stored which is C0020-01 This is a known problem with Chrysler as they have produced TSB #[XXX] for this issue. This is a known faulty part that could cause an accident due to ABS malfunction. I feel Chrysler should be forced to remedy this issue for all 2017 and 2018 Ram owners since it is a safety issue. My vehicle is a 2018 Ram 2500 Tradesman with less than 33000 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

hydraulic control units and anti-lock braking systems keep giving an error code.

ABS and traction control systems are inoperable. Dealer diagnosis in December of 2022, says ABS control module and Hydraulic Control Unit (HCU), are bad. Ram has failed to supply functional parts to affect the repair. It has been 14 months awaiting parts and Ram/Stellantis has no proposed date for when the parts will be available. I'm scared to death to tow anything (especially on wet pavement) without properly operating brake controls. This is dangerous condition and NHTSA should do something about it.

The Antilock and Tracktion controll lights come on and off with a chime while driving. It also disables my Cruse Controll when it goes off.

ABS is not functional. HCU and ABS Pump are failing and there are constant service lights that come on. Is very dangerous and dealer claims part is back-ordered.....Extremely dangerous to not have proper ABS.....

2018 Ram 2500 has ABS and traction control light always on. Will sometimes go off and then come back on. I contacted the dealer yesterday [XXX] at Mcpeek in Anaheim, Ca and they told me opart is on back order. No recall. This is dangerous and I do not know if it will affect brakes and traction when I haul different trailers. Ram manufacturer should take care of this issue. Dealer also advised me they have been getting many complaints regarding this dangerous problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Warning lights and audible warning for ABS and emergency braking along with traction control have been active for several months. Dealer determined the ABS control module is faulty and needs replaced. Current lead-time for the part is 7 months and cost to replace is $1,200. While the warning is active the cruise control and traction control are de-activated. During a recent rain storm I had to accelerate to avoid a merging vehicle on the freeway and the rear tires broke loose due to the lack of traction control and sent me into an uncontrolled fish-tail across 3 lanes. Fortunately traffic was light and everyone was able to avoid me and I got it under control and stopped just before hitting the freeway barrier wall.

Over the last several months my 2018 Ram 2500 is experiencing intermittent service abs traction control system issue. The lights on the dashboard will go on and off and it will "ding" when it does. I am very concerned from a safety stand point as I know this system is supposed to help with braking in an emergency and assist with keeping the vehicle under control in adverse road conditions. The truck only has 35,700 miles on it now. I have taken it to the dealership and they are not able to read any trouble codes. Thank you for any assistance with getting this corrected. Ram needs to recall this issue as I have done some research and have found this to be a very common problem with this year make and model vehicle.

The abs light and traction control light have been flickering for years. Now they are on solid. When I went to the dealer they said the part is under engineering review and they can’t fix it anyways. My truck now won’t pass safety inspections and can’t be reregistered

The vehicle has lost all antilock brakes Lights on dash warn there is a issue with vehicle safety capabilities. The trailer brakes will not activate. Dealer says common issues with 2017 2018 and cannot fix due to parts not available for a year. People are putting their lives in danger operating this truck with this issue. I have had work on this problem before costing thousands of dollars. I can't belive you let them effectively shun safety and lives.

The ABS module on my 2018 Ram 2500 has failed. It is throwing a C0020-01 code. As a result, the ABS and traction control safety feature are no longer working. The warning lights for both are displayed on my dash.

Warning light to service the Electronic Braking System came on. Has been intermittent since. Contacted dealer and the HCU needs replacing. Vehicle is under mfg extended warranty. They claim part not covered. There are hundreds of complaints about this along with a class action lawsuit filed last year in CA. Brakes may fail without repair. 4WD will not engage since warning light came on. Lawsuit alleges Chrysler knew of this defect before selling. I have scheduled a replacement of the unit for 3/1/2024

The truck last year started flashing the ABS and traction control lights. On the screen it says I have to service my braking system. As soon as that warning comes on, I lose traction control and it’s awful to dry in snowy or wet conditions. The truck just hit 28 thousand miles. I contacted the Ram dealership and they are aware of the issue but stated there is no recall so they’re not addressing the issue.

We purchased our Ram 2018 /2500/4WD Mega 6'4'' Larami in 2019. I only had 7,853 miles on it. When we drove the truck to Tenn, the Abs and traction control lights kept coming on the display. This kept happening throughout the trip. On [XXX] we had returned and taken the truck to Dodge dealership for inspection. They performed diagnostics and found Abs motor internal failure, this was replaced, and the brakes were bleed. The code was: C0020-01. The truck was still on warranty. On [XXX], once again we had the antilock brake system / Elec braking system light came on the display. Verified concern found Abs code module internal at this time rec replace of Abs pump. (Direct wording on invoice). Truck still under warranty. In Dec 2023, we returned to Dodge dealer again for constant display of the Abs traction control lights flashing on and off. We started videoing this to prove the problem had NOT been fully fixed. We were told by the dealership that the HCU part was not available till spring or summer of the following year. By this time, the truck is no longer under warranty. This problem is not only annoying, but the issue of safety is foremost. We don't drive the truck in the rain for fear of losing traction. We have a boat that sits there because we are concerned about stopping the load. This seriously needs to be addressed by the manufacturer. I have read several accounts of other owner experiencing the very same issues. I don't want to have to pay out of pocket for a problem that had been documented and supposedly fixed two years ago. This needs a permanent solution. This truck was a large purchase for us, we are not using it to its fullest potential due to problem.

The Hydraulic Control Unit Chrysler part number 68143491AA failed and has not been replaced yet. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. There were no Warning lamps/messaged before failure only after. These would be ABS lamp and traction control lamp plus a service ABS warning message. It flashed intermittently for months before finally staying on permanently starting a couple weeks ago.

The abs/traction control message goes off intermittently. The truck dings and beeps from the dash with a message that says “service abs”. This is a known issue with this yr/make truck.

Warning lights for ABS and Brake system flash on and off continuity while driving at any speed or stopped, with a message displaying "Service Electronic Brake System" and a warning chime. This typically occurs once every 2-3 seconds. Truck was taken to Local Ram Dealership in Early October of 2023 for diagnostics. Dealership stated issue was the hydraulic control unit causing the warnings, but parts were on hold for inspection by Ram so the issue could not be repaired. As of Feb 2024 the dealership has informed me the repair parts are still on hold at least until April 2024. The hydraulic control unit problem disables ABS, Traction Control Stability Control and Cruse Control systems.

The abs and traction control light come on. Failure in the abs module

Service electronic brake system code came up. Brought it to the shop and they said it’s a known issue with this year model and ram is aware. Told me it’s a $2500 fix. I feel that a safety issue that is know and I had to fix myself is not fair in its self not safe!

ABS and traction control system failure. Allows dangerous wheel lockup in snowy or slippery conditions. Also cruise control function failed. The warning lights sometimes cease and cruise control function resumes however the function will suddenly fail when warning lights resume. Tires have locked up several times in snow and created momentary loss of control. In addition, sudden loss of cruise control while in use causes sudden loss of speed while at freeway speeds. Dealer says that ABS and HCU modules are bad. Vehicle has not been inspected by mfg, police, insurance. Was reviewed by dealer. Warning lights for ABS started appearing in September of 2023 and before there were any wheel lockup issues. The cruise control function failed immediately when warning lights appeared.

HCU hydraulic control unit the ABS light and traction control intermittently coming on and going off this has been an ongoing issue for nearly a year. This has been “replaced” once already. It is now out of warranty no parts available to fix. I pull a camper if this malfunctions while pulling camper this could tragic for my family. I called dodge they provided absolutely help. This is a known issues and Texas and California have class action lawsuits over this part with dodge. This truck only had 49,000 to date. We need help getting this part recalled before someone gets hurt.

I have an intermittent abs warning that turns off abs,traction control, and makes the truck brake worse when it happens. Diagnostics indicate a abs pump failure performed at dealer and an independent shop. Dealership says there’s a hold on the part from Chrysler engineering. I have been informed it’s several of the 2017-2018 2500 rams and makes driving the truck dangerous.

My ABS notification light continues to come on. I had body work done at a collision center for the rear quarter panel and when they had their mechanic inspect it, he determined that the ABS module was faulty. Additionally, the collision center indicated there is a current class action lawsuit for the very same part. The ABS and traction control will go on intermittently and continues to do so the entire time the vehicle is driven. Fortunately, I haven't had any accidents as a direct result because I refuse to take long trips or travel on the freeways for fear of it failing when needed most. The part is almost impossible to locate and when there is one available its either grossly overpriced or reserved within minutes of locating one.

ABS control unit failure

2018 Ram 2500 6.7 L Problems with ABS Module Control. Replaced in October of 2021 now bad again and on back order with no date available. This module controles abs braking, traction control which are safety items designed into the truck. I've had the truck to 2 different repair shops and both confirm the problem and both tell me that Ram is having a problem with this part and the the part is on backorder

ABS service light comes on intermittently causing inconsistent braking, especially during bad weather. I need to know I can count on my anti-lock brakes. Many calls to the dealer service center and they say there is no fix for the problem. How can this be? Brakes are a fundamental necessity for a vehicle. They won't / can't fix this? Please investigate. I know I am not the only person with this issue. My brother owns the same 2018 RAM 2500 and he is also having the issue. Also, there are thousands of complaints about this online. Please investigate and keep Stellantis accountable!!!

ABS light and traction control yellow warning lights are illuminated on dash. It Also chimes when it appears. Going to dealer Thursday 2-22-24 to scan a code and be put on the waiting list.

ABS light and Traction control light came on. Shows code C0020-01 which is for the ABS pump motor control failure, which also works with the hydraulic control unit This part not working can cause the vehicle to go out of control while braking due to lack to ABS and also to go out of control while driving/accelerating due to lack of traction control. The code was verified by a national parts dealer The component had not been inspected, although many Ram owner online forums show that this is common part failure on trucks that are not even very old or have high mileage

Abs General Electric failure. I don’t have traction control or abs and I live in the mountains where these systems are necessary. Very unsafe and parts aren’t expected till June 2024

The abs / traction light continues to flash on and off. When light is on the abs and traction control does not work. Cruise control is also disabled when the lights come on. To repair the problem is a 1,000 dollar abs aluminum block and abs module. Plus labor. Thank you for your time and help

Service abs system and traction control

The truck constantly has an ABS Module and Stability control failure/ code turning on and off causing the ABS/ Cruise Control/ Traction control to no longer function. Research shows that the ABS Module and Hydraulic control unit need to be replaced and programmed by a dealership and parts are nearly impossible to find

The abs system failed and caused the cruise control to not function as well as the trailer brakes not operating. It has been inspected by a certified ram dealership in Corscanna, Tx and confirmed that the abs system is out. The abs warning lights comes on and off, on a 30 mile trip it will come on and off 15 or 20 times. This started in May of 2023 on a planned trip of 330 miles pulling a 10,000 pound Rv. The Ram dealer told me the parts would be in in August of 2023, and then in Oct of 2023 and then Jan of 2024, and now April 2024. The dealer tells me it will cost $1600.00 to repair it. I have warranty but no one can get the parts. Thanks

abs module failure. first time covered under warranty at 11,906 miles. second time not under warranty at 24,786 miles, and currently in failure mode.

ABS and EBS warnings, traction control warnings repeatedly turning in and off. Code - C0020-01. Cruise control inop when lights/chimes are going. This has been going on for nearly 8 months.

Service Antilock Brake System Service Electronic Braking System Illuminated warning lamps. Impacts Braking and cruise control. Started 10/2022, and appears to trigger randomly and frequently.

The traction control/service abs system on dash came on following the loss of vehicle cruise control while driving on busy 3 lane of traffic during hill climb causing instant loss of vehicle speed. Was last told by local mopar dealer no parts available, no idea when available. Vehicle had no cruise or traction control. Only 39,000 miles on vehicle currently. Independent service center pulled code C0020-01 abs pump motor control- general electrical failure. From ECU

ABS module failure. HCU failure. Braking system completely out of whack. I purchased the truck new. Warranty is expired. Many many complaints online of the same problem. Parts are unavailable to fix. RAM needs to fix this shit asap. Get a recall going. This is completely unsat.

I have been having antilock braking system and electronic braking alerts come on the dash of my 2018 Ram 2500 for a couple months now. I have tried to have it repaired at the Pohanka Ram in Salisbury, MD in which I was told that the ABS module and HCU unit were under "engineering review" and all parts would not be released to repair. I also confirmed with the Lakewood Dodge Dealership in Seaford, DE and IG Burton Ram in Georgetown, DE. All 3 dealership report the same issue that RAM will not release the parts for repair. I have a truck that is an obvious risk on the road, and will not pass Delaware motor vehicle inspection in March when my tags end. I have seen that there is a class action lawsuit and a huge amount on owners reporting to this agency. This is huge issue and is affecting a large amount of people that own 2017 and 2018 Ram trucks.

The truck began flashing problems with the anit lock brakes and electronic brakes off and on. For over two months now, the service lights stay on along with the traction control warning light. I have called multiply locations trying to locate replacement parts to no avail. The brake pedal sometimes is difficult to push and the antilock brakes failed at a slow speed once. I have reached out for help several times and keep being told that the part is not available and will not be available for months. Last time before today I was told Feb. I called today and was told it wouldn't be until June. This is my only vehicle to get back and forth to work and to get my son to athletic events. I really need this problem corrected.

1 abs warning light and buzzer come on every 2 mile which is a distraction 2 if warning does stay off for 5 miles and speed control is set will work but when warning goes off speed control kicks off causing traffic flow problems almost got hit from rear got honked at and finger 3 been waiting for over a year for part dealer says it is not available 4 called dodge ram phone number for complaints got nowhere

The truck flashes service antilock brake system, service eletronic brake system. It cancels the cruise control on truck. On several occassions it shuts off cruise while on the interstate. You have to react very quickly to avoid having an accident. A couple of times its happened while pulling a travel trailer and nearly got rear ended by semi truck. Thats really scarey. It started about 8 months ago. Have contacted dealer and was told by service department that they know of about 2000 trucks has same issue. The parts are out of stock and back ordered. I think this is a real safty issue. Dont know what to do about this.

Hcu, hydraulic control unit, no abs, no traction control, no cruise, no 4x4 and emergency brake light on won’t go off and part is not available been waiting for over a year and a half

My 2018 Ram 2500 had an issue in 2022, where it was throwing a "Service Electronic Braking" light. Came on and off, caused the traction control light to come on as well. Additionally, this disabled the cruise control. I paid $1200 roughly to get this fixed because it was not considered part of the drivetrain warranty (50k miles). 16 months later, my truck is having the same issue and Ram wants to charge $1400 to get this fixed again.

Vehicle is displaying a “Service abs” warning on dash intermittently. It has disabled traction control and cruise control. Parts from the dealer are currently unavailable. After researching I have found that this is a common problem with this model and year vehicle.

Two years into owning this truck the ABS control unit went out (a known issue) and was repaired by the dealership under factory warranty. Two years following that repair, same issue; however, this time the issue is more severe. The intermittent service ABS system light/alarm is not as delayed between alarms and during normal braking the brake pedal firmness changes. On one occasion the pedal was so firm almost couldn't depress it and when I did, it locked up the back tires. This braking system should not be trusted and emergency braking with it... let's just say that Fred Flintstone braking system could be a better system. Available for inspection: yes. On going issue since Spring 2021 (I took delivery of the truck in Jan 2019)

ABS Brake module has failed which makes it dangerous in certain conditions to brake/slow the vehicle. Also the TPMS system, Cruise control, and all 4 wheel drive components will not work as they are processed through this module. This module failed in October 2023 and is unavailable for my mechanic to fix my truck. It is now February of 2024 and I am being told that this module will not even be available for order for my mechanic to fix until June of 2024. This is dangerous and unacceptable to have a braking system not working properly for 8 months or more! Service ABS system, TPMS light, and Traction control lights came on when this first happened in October of 2023 and have stayed on constantly since then.

(I had to pay for parts and labor on ABS replacement that RAM neglects to issue a recall.) this costed me $1,252.11 April 16, 2023 — A Ram ABS module recall allegedly should have been issued by Fiat Chrysler because of problems in 2017-2018 Ram 2500 and 2017-2018 Ram 3500 trucks.

ABS BELLS GO OFF ALL THE TIME AND SAYS SERVICE ABS , CANT EVEN GET THE PART , NON STOP PROBLEM .

2018 Ram 2500-continued failure of ABS system-ABS warning light and service ABS system error code come constantly. When code is on ABS braking system, cruise control, and 4 wheel drive do not work as well. Truck has been serviced 3 times for this issue and dealer says ABS module needs to be replaced but they do not have a fix or the parts available to fix it at this time from Ram.

abs lite comes on. service electronic braking system message. cruise will not work when fault is active. second time for this. fixed first time under warranty. truck only has 60k miles.

The ABS light has continuously turned on the last two years of owning the truck. We took it to a mechanic that informed us a recall should be called because it was a common problem that 2018 Ram 2500 have been experiencing. A recall still hasn’t been called even though many people have had the same issue.

The anti lock brake system has failed on my 2018 Ram 2500. This has been confirmed by the dealer as well as an independent shop. First case was hauling a trailer full of wood, a car pulled out in front of me, I slammed the brake and the anti skid failed, brakes locked up. The only reason I didn’t completely lose control is my trailer brakes worked and stopped the swerve. Since that day the ABS light has been intermittent and is becoming more consistent. Because the light is intermittent the other symptoms are intermittent to include cruise control and the most critical; traction control. This problem caused me to lose control on black ice in Hastings MI about a month ago and swerve into oncoming traffic. No accident resulted. This is a known problem on this truck and there is a technical service bulletin published as well as a class action law suit. Because of this myself, as well as other owners, are reluctant to pay thousands to fix it because we are awaiting action from your office to drive a recall. I recommend action to implement a recall before someone is killed due to this faulty system. ABS light is illuminated as well as Service Anti Lock Brake System Message. Systems lost are anti lock brakes, traction control, cruise control.

Abs/traction control lights keep pooping up on the dash. The dealer has changed the abs module and it didn’t last long. The truck has 28k miles. It definitely can cause an accident because I haul heavy loads a lot. If the abs brakes doesn’t work correctly I will crash into another vehicle. And it dings/ beeps every time I push the brakes or every time I hit a bump or something. I hope Ram can come up with a recall to fix this issue soon. The contact stated he fixed the ABS issue on the 2018 Ram 2500.

Got in my truck one day and my ABS and Traction Control Lights both came on, as well as a notification in my central dash advising to service electronic brake system. At first the lights where intermittent and random. I could start the truck and the lights would be off. Apply the brakes to put in gear and the lights would come on. Drive down the driveway and a bump would turn them back on and pressing the brakes would turn them off. Now the lights stay on permanently. The ABS error code I got was C002001, or ABS pump general electric failure. I called several local mechanic shops and they reported to me that this is a known issue, parts are on backorder. I called the dealership, was advised the same with the addition that Dodge/Fiat, not only new about the issue, but changed upgraded the part and gave me the new part number, which is also on back order. Knowing this vehicle is a diesel and is designed for towing, which is why I bought it, to pull my trailers and equipment, the brake system is vital to stopping the vehicle for my safety and everyone around on the road. If this is a know issue across the nation, this needs to be addressed.

Repeated warnings on and off that ABS was defective. Would turn on and off repeatedly while driving. Service ABS system alerts.

ABS and Traction Control light keeps coming on. Code C0020-01 ABS Pump Motor Control General Electrical Failure is being read.

The ABS light goes on and the warning bell starts dinging. This is a safety problem as you don't know if the ABS is working or not. Dealers don't seem to think there is a problem with this. I looked online at [XXX] . And there are quite a few examples of this problem as well as what dealers are not doing. Going to this web site look for "2018 Ram, ABS and Traction Control lights. This seems like an ongoing problem that no one is looking into. One guy took his truck in, and they said they couldn't get parts to fix it for five months, but the truck was fine to drive. 11 blocks from the dealer he rear ended someone because the ABS was malfunctioning. Therefore, this is a safety problem and should be looked into by Ram and a recall issued for repairs. And when the ABS light is on you cannot use cruise control INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ABS control unit has gone out for 2nd time. Replaced at 15000 miles and at 59000 miles same issue and no resolve from Ram due to parts not available. ABS, ESP, Brake lights continue to show on dash. Cruise control and push button start effected and not working..

ABS module indicator alarm chime is going off. Dodge says part can't be ordered until June 30, 2024. Vehicle is unsafe and Ram refuses to work with me.

I am receiving intermittent, but frequent, ABS error while driving. The alarm dings and cruise control is disabled. Most times it happens every couple of minutes but every so often, it will go several minutes without the error and alarm noise. It also goes on and off when hitting bumps in the road such as crossing bridges and going over the expansion joints. As off yet, I have not had any troubles braking but am afraid that I might. 1- The ABS/HCU module. Yes it is available. 2- Possible difficulty or failure in braking. 3- It has not been to the dealer yet. I read this is a very common problem but no recall has been issued? 4- No. It has not been inspected yet. 5- Alarm sounding and "Service Electronic Braking System" displayed on dash.

The truck has low miles only about 50K and my ABS lights go on and off randomly. Now when I am driving I randomly have ABS lights go on and off and I believe that the issue is with that ram ABS unit and control module. I have been told that the fix will involve replacing both pump and control module. I tow with this truck in all weather and it's not safe to be driving without a working ABS. The ABS error code I got was C002001.

ABS and traction control lights came on. The dealer said that it was the control module. It has been replaced. There were no braking problems but concerned that it would eventually be a problem.

This vehicle has faulty or defective ABS braking system. The warning lights and warning chimes have been constantly going off for approx. 2 years. The Dodge/Ram dealerships admits that this is an industry wide defect with 2017 and 2018 Ram 2500 trucks, but say they have no parts to correct the problem. Their suggestion to me was to buy a new truck which is not acceptable or affordable. This was identified by both the dealership and Chrysler as being a safety issue with no resolution from Chrysler or dealer. I use vehicle to transport my grandchildren and livestock and truly doubt my ability to operate safely without the Federally required working ABS system. This is truly a safety issue and an immediate recall is necessary. Ram/Chrysler will not correct issue without recall. I am limited on the use of my vehicle but have no choice as it is my only transportation, thank you.

Ongoing condition. Automatic break system communication along with traction control. Causes service ABS warning light and traction control warning light. Disables cruise control causing instant and unexpected speed loss. Causes loss of traction unexpectedly with failure.

ABS, anti-skid, and cruise control inoperable for 3 years.

I keep getting an ABS/Traction control warning on my 2018 Ram 2500 I was told this is a common issue and the parts for repair would be over $1,000 dollars. I am an ASE certified mechanic in the field of brakes. This is a safety item that should be under a recall if those systems go down not only do you loose the ABS/traction control but you also loose four wheel drive. That makes driving in the northeast very hazardous on roads covered in snow and ice.

Traction control light and ABS light periodically comes an on off. Screen reads service brake system.

ABS and traction control go off and on constantly while driving. When doing so lights on the dash come on as well as a loud chime. Besides being very annoying, it makes the vehicle unsafe when not having ABS and or traction control at any given moment. This started happening when the truck only had 5,000 or so miles on it. I couldn't get it "fixed" because of COVID, and the dealerships have no parts/ back-ordered. I've heard that many others with same problem, had things replaced by the dealers ( at their cost) and it comes back again. This should be a recall !!!

ABS warning light comes on frequently. It was diagnosed as a faulty ABS pump motor by a Dodge dealership on March 31, 2023. I was told then that the replacement part would not be available till August 2023. I called in August and was told that it would not be available till February 2024. I called in February and was told it’s not available till June 2024. The Dodge dealership parts manager told me they have 11 trucks with the same problem they are trying to service. So far we have spent over $700 in diagnosing and trying to get the problem fixed.

ABS and Traction Control light and alarms activated inside cab on dash. Vehicle taken to dealership and they stated the HCU (hydraulic control unit) needed to be replaced. At that time no parts were available and a time frame was not given because no one had the parts not even after market. After several months of driving vehicle with out ABS or Traction Control vehicle has been fixed.

2018 69500 miles tradesman 6.4 hemi 2500 has anti skid lights and skid module light on randomly dealer cannot fix parts on order 6 month this is a safety issue with no help from dodge dealership vehicles that have this system now none [XXX] [XXX] [XXX] thankyou for looking into INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have replaced the ABS/HCU 2 times as of 1/1/2024. I am currently waiting for the 3rd one. The ABS system is unreliable and dangerous during the time of waiting for parts availability. The dealer diagnosed the vehicle in 10/2023 and has been unable to get parts to repair the problem.

I bought my truck, a Ram 2500 with the Cummins diesel engine in August 2018. When the truck had 20,000 miles on it the ABS and traction control lights, chimes and notice came on. I took it under warranty to the Dodge Ram dealer where I bought it. They did diagnostic tests and replaced the ABS control unit and ABS module under warranty. The truck now is out of warranty with 76,000 miles on it and the ABS and Traction Control lights, chimes and notice on the dash screen have returned. I will take it to a local Dodge Ram dealer and have the problem diagnosed soon. I feel that these issues are a safety concern and are due to faulty parts used by the vehicle manufacturer. As such, my vehicle should be included in a safety recall and fixed at the manufacturer's expense. Thank you.

Abs light in the dash came on intermittently then constantly. Took the vehicle to Nemer Ram in Queensbury ny. They replaced some parts, but problem continued. They said abs module is bad and said a new one has been ordered but there is a national back order and no info on timing of receiving the part. Told me to take the truck and drive home. They said abs system May or may not work. I have driven it for two weeks since and have had some very dangerous situations in rain and snow where brakes locked up and skidded, so abs didn’t work. This is a seriously dangerous situation that forbids me from driving this vehicle in wet or snowy conditions. I live in northern ny, where it snows and rains often, so I can barely drive this vehicle. Dealer told me to call Chrysler customer care, which I did today. I have a case #[XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The ABS module failed and was replaced April of 2022 at Terry Hendricks Ram in Archbold Ohio under extended warranty. Now I’m in Titusville Florida for the winter and same issue, ABS lights and service traction control with the constant dinging. Parks Chrysler Ram here has order same part again, they said will take a couple weeks to get a replacement as there’s a waiting list because it’s a on going issue with these trucks. 51,000 miles on it and stated there is a 2 year warranty on this part. This now does not have the antilock working again and could be a safety issue. Should have a recall on this.

Abs and traction control light going off and on causing abs and traction control to be disabled. Safety issue being able to control vehicle if had to get on brakes hard Problem was able to be reproduced by the dealer and this has been replaced once before on the truck while under warranty, Component has been inspected by dealer and found faulty on November 16 2023 but informed it would be late January 2024 before they would have parts, now it is late January and they say parts are in the development phase and would be late June or July before they might have the parts. Concern is have a 2018 truck with just over 32000 miles on it that has had the same issue twice and they can not fix, Advised by dealer and ram customer service that they advise not to drive truck, but they will not loan a truck during this time but could rent one at my expense

Service abs sensor has already been replaced by the dealer and less than 2 years later the problem is back . Dealer says major wait for part. Nobody makes it .so now I have to drive a truck with faulty abs. Very unsafe. My research shows some people told a year wait for part. How do I even sell it with the dash all lit up and pinging every couple seconds. Why is this not a huge recall for safety alone. Any advice is welcome. Thank you

I am the owner of a 2018 ram truck. this is a 2500 series for wheel drive the ABS module failed approximately two years ago and I have not been able to get Chrysler to provide part for repair. The vehicle has 225,000 miles on it at this time and we are continuing to drive it, the ABS or cruise control or traction control because these are all related to the ABS module/pump

I purchased a used vehicle from Victory Dodge Dealship in Kansas City three days later, the ABS traction control all my sensors, cruise control four-wheel-drive locked out on me, kicked out the cruise control on the highway was not sure what was going on someone behind me almost ran into me thought something was wrong with the truck, so I went to pull over slowly hitting the brakes like I normally would but the brakes locked up due to the fact ABS shut off almost crashed my truck Now to find out, there is a huge problem with the ABS control modules going bad, and my Dealer says they’re not gonna cover it even though I just bought it and the part is unavailable for the next 6 to 8 months There needs to be a nationwide mandatory recall from Dodge on this part as it’s been a problem for countless people, and it is a safety issue that needs to be dealt with some kind of fix and replacement needs to be made there’s regular hard-working people out here that these things break over and over and over again and don’t have the money to fix something that should not be breaking Please push for a recall on the ABS system on these trucks and come up with a replacement that will not malfunction or break Thank you

While driving the ABS lights flash on and gives warning the ABS system need service. Also traction control light comes on and cruise control stops working. Ram knows there is a problem with 2017 and 2018 2500 and 3500 AB S module.

"Service ABS System" came on dash after normal braking entering a intersection. Truck pulsated and didnt allow brakes to be applied as I entered the intersection. No collision. ABS warning continues to come on

Abs system continuously inoperable causing antilock system to not work and distracting driving due to alarm constantly chiming then resetting and then starting again

I get a warning that flashes on the dash multiple times every time I drive stating that I need to service the electronic braking system. This warning is also accompanied by the traction control and ABS warning lights. The warning and lights do not stay illuminated and flash on and off several times during the course of even a short drive and the warning bell sounds every time as well. At minimum this is a huge distraction when driving and even worse I do not know if I can trust the brakes in the event of an emergency stop. I looked at fixing the issue by replacing the ABS and HCU units, but those parts are back ordered well in to 2024 now. Reading on various forums, this problem seems to be pretty common, but as far as I know no recall has been issued by Chrysler.

ABS and Traction control light continuously comes on.

2018 Ram 2500 26,000 miles anti lock brake system light goes in and out while driving. This also causes the alarm to ding continuously while driving. This makes for distracted driving not to mention the safety of the braking system. I personally know 3 people with the same truck same issue. When I took it to dealer they started the diagnostic test and stated that it was the brake module. They also stated they do not know if any reoccurring issues with the module. I realized the dealer wasn’t gonna help me and pulled the truck from the shop. I am writing to you guys out of concern and frustration. This should be a recall due to the size and weight of the vehicle. 2500 trucks are designed to tow heavy loads and I do that with my truck. I currently will not pull any thing due the safety of me and the public. I’m hoping this help get my truck back on the road and safe to drive.

ABS and traction control lights on randomly. See a lot of complains online of similar models.

ABS and Traction Control light on . This cancels out cruise control also. Vehicle was repaired at 23562 miles and is out again at 32000 miles. I have been on dealers waiting list for over a month. The part used for the repair must have been defective also. W11aiting time for the repair is entirely too long. Antilock brakes are a safety concern and should be quickly fixed.

Since incident, the messages continue to appear in my dash. "Service Antilock Brake System" and "Service Electronic Braking System", flashing on and off erratically. I talk directly to Mopar which is overseas, and they tell me it isn't covered because its under the basic warranty which has expired. I asked them to send me the documentation so I can see it in writing and they said they cannot send it or show it to me and that only they can see this information. I am concerned that they are not being honest with the warranty coverage because my five year/100,000 expires in June 2024; and ironically they said the ABS part isn't available until June.

ABS and traction control warning lights keep coming on and I have either impaired brake performance or loss in braking at all. I have had the codes ran and the ABS module keeps coming up as a failure. The warning lights sometimes come on just while driving or when hitting a bump in the road. They stay on for the duration of the drive and sometimes will turn off randomly.

Electrical warning for electronic ABS Braking System and Module to include traction control. Initial evaluation at Dealership on 10/25/2023 Since then, the parts have been order, but unavailable through the dealer or through the Customer Care team at Dodge. Multiple phone calls, emails, etc., and still the parts have no estimated delivery. No solution has been offered by the Dealer or by Dodge and the truck is unsafe to drive.

Abs control unit is bad at 35725 miles. Part is back ordered until atleast April. Truck is under warranty but they won’t give a loaner until repairs are being made. I’m supposed to drive the unsafe vehicle until then and make payments on it. Dealer has been great. This is a ram problem. This is a known common issue they’ve neglected to remedy. Completely irate.

Code C0020-01 appeared. ABS pump motor control- General electrical failure. Problem occurred in heavy snow storm. Traction control would not work, anti-lock brake system would not function. Brakes locked up causing vehicle to skid.

This truck has an intermittent "service electronic brake system, service automatic brake system" caution message displaying on the vehicle dash. It has become more frequent and disables the cruise control, stability traction control, and ABS. The same issue happened in May 2021 and was addressed with the dealer at that time with code C0020-01. Under warranty the ABS module and HCU were replaced and the problem was corrected til December 2023. This same issue happened again showing code C0020-01. The truck is no longer under warranty and the dealer states that I will have to pay for this repair. This seems like a common issue on these trucks and needs to be addressed with the manufacturer. I have included the invoice from repair in 2021.

Electronic Braking System Needs Service Error that can't be addressed at the dealership.

I had an intermittent abs/traction control light that now stays on 90% of the time. Code C0020-01 for ABS general electrical failure.

The truck developed a warning light for ABS / Stabilitrak needing to be serviced. Ram dealership replaced an ABS Pump, but the issue came right back. They are now saying it needs a new control module at great expense, but that they are unavailable currently. Delivery on the part has been pushed back continuously over the last 12 months, still no parts. This issue causes a regular intermittent digging and warning light in the cab, disables ABS, disables Stability Control, Disables Traction Control, and Disables Speed Control (Cruise Control). This issue has been ongoing for 8+ months at this time with no developments from Ram and the vehicle in an unsafe and compromised condition.

Service anti lock braking system and electronic brake system code constantly coming on. This is an apparent safety issue that Dodge needs to resolve. After much research, I’ve discovered that there are many, many complaints of 2018 Ram truck owners having the same problems. Thanks for all your assistance.

The ABS module failed. This resulted in the ABS function not working along with cruise control. This seems to be more common with this model year. Warrant did not cover this so I had to pay the dealer to replace the ABS pump and ABS electronic module .

Electronic Braking system failure affecting the ABS system, Traction control, and cruise control. It puts the safety of everyone in the vehicle and on the road at risk because the ABS and cruise control will fail causing an unexpected adverse conditional that can lead to an accident. This is a known problem for RAM and their is no fix at this time other than making the customer pay out of pocket for the broken parts to be replaced with the same parts that will fail shortly after. There needs to be a recall and a permanent fix from RAM

ABS and traction control lights keep turning on and off. Truck currently has no ABS.

ABS warning lights came on while driving, early October 2023. Dealer diagnosed problem as faulty pump control, faulty module. Lights continue to flash while operating vehicle, along with the cruise control being disabled. Dealer has pump control, module is unavailable, with no known date of availability. Therefore a repair has not been made and I have no choice but to continue driving the truck in unsafe condition.

The ABS lights and traction control lights alarm keeps flashing on and off at random intervals) on my 2018 Ram 2500 4x4 with 18,000 miles on it. When the ABS Light and traction control light come on intermittently it also disengaged the cruise controls. At first it was here and there or when I hit a bump or turning the steering wheel right or left. Thought it was possibly a wheel speed sensor. Checked code with scanner and got “ABS pump motor control-general electrical failure”. Thought the issue was the ABS module based on my scan. I tried to find the part I had to call all over the place due to supply chain issues. When I spoke to a parts person from a dealership I explained the issue and code. He stated that the General Electric code failure was the HCU and not the ABS module. It’s bad when your cruising at the speed limit of 70 mile an you and the cruise control quits working an you ned to react to the traffic but, my real concern is that the ABS won't work and could cause the truck wheels to lock-up during a panic/hard stop.

Service Antilock Braking System and Service Electronic Brake System will begin to constantly flash on the dash. It would display the ABS light and the Traction Control light. At this time it would also turn off cruise control while traveling down the highway. I purchased the truck with 62,000 miles on it on 12/28/2023 and the issue occurred on the way home and ever since. Since I was not aware of this issue, the truck slowed down and I was almost hit. I had to pull off the road to figure out what was going on.

The abs module is not working and yhe braking is hard to use.

ABS Service Required Light and alarm and Electronic Braking light and alarm are coming on and going off. Just started in the last week. Apparently this issue has existed since 2018 with no recall issued to date. ABS module has not been available and shows Discontinued. I have not been to the dealer at this point, but from research the problem is a bad ABS module from factory. Hundreds of other trucks are affected with no resolution. I have to tow a 38 ft trailer and it may be unsafe if ABS fails. I do NOT want to have an accident and destroy my truck and trailer and/or have my wife and I injured or worse. The vehicle is available for inspection. I would be certain that the threshold for complaints has been met. If you are serious about vehicle safety, you will put a recall on the affected vehicles and require the parts be made available for repair sooner than later. I have seen where people have waited several months and still have no parts. Also, the cost of repair out of warranty is somewhere between $1200 and $1700 . For a manufacturer defect this should not happen. Please issue a recall!

ABS and traction control warning lights intermittently. Loss of cruise control. This appears to be a known problem with an expensive repair.

Coming down a ridge with a loaded hay trailer approximately 14500 pounds, the Service Electronic Braking System and Service Automatic Braking System messages appeared in the cluster EVIC display and the service brake and traction control warning lamps illuminated and there was associated chime. I applied the brake pedal and it went to the floor with zero affect. The trailer brakes didn't respond either. I used the exhaust brake and skillful downshifting (it has a manual transmission) to slow the vehicle and then used the foot applied emergency brake pedal to bring the truck to a stop. I was lucky I was already carefully descending off of the ridge and I was able to downshift and slow before engine RPM became an issue. I cycled the ignition and the warnings went away. I very carefully and very slowly completed my descent off the ridge. Now the warnings, light, and chime are incessantly coming in and then just as soon turning off. I don't trust the truck is fit for my purposes at this point in time. I hadn't been that scared since my dad and I lost a rear axle and brakes on our 1969 Ford F-250 with a load of wood in the back coming down a mountain road when I was 12.

Service electronic brake systems, service anti-lock brakes. replaced under warranty and now the light comes on intermittently. Obvious problem with the Ram trucks

Brakes when depressed do not pull equal. No cruise control. 4 wheel drive is not working properly. Traction control not functioning properly Have brought vehicle to a garage. Abs/hcu unit is the problem.

My 2500 hydraulic control unit is causing light to constantly come on and go off causing cruise control and ABS lights. This is a rampant issue with the 17-18 year truck but no recall. The part is bad that cause the manufacturer to come out with a replacement part but still no recall and this is the second time it’s happened the first time it was under warranty. But not this time.

Abs dash light

ABS and Traction control has been lost and have created a safety risk especially during inclement weather. The ABS pump or the ABS control Module is faulty in multiple years Ram vehicles. I believe based on forums there is a recall issue with these parts.

Antilock braking and traction control system failed. I was driving on a snow/ice covered road and hit the brakes with no anti lock control and truck slid in road side ditch. Truck has not been repaired. This is a known problem that Dodge is well aware of. This could have caused serious injury or death under alternate driving situation or heavy traffic. Any help would be greatly appreciated.

I’m receiving two codes; Service Antilock Brake System and Service Electronic Braking System. I met with my mechanic this morning and he said that this is a very common problem with the 2018 Ram 2500. Since this is a reoccurring safety issue i feel that Dodge should resolve not the owner. Should I get in an accident from a break failure who is responsible?

I have a 2018 Ram 2500. Service anti-lock brakes message is intermittently coming on and off. This occurs every few seconds while driving the truck. I took the truck to a repair facility and was displaying a code for the ABS/hydraulic control unit. I learned that there is not a known replacement to solve the issue. I have connected with other Ram owners who are dealing with the same issue while replacing unit multiple times. Ram needs to address this issue, I and along with many others are driving with no anti-lock brakes.

I spent close to $1,700 to replace hydraulic control unit (HCU) at a local dealership on 4/7/2022 when my pickup truck was only 25,392 miles. Since the flashing of ABS/Traction Control lights did not stay on, I paid for the first diagnostics at this dealership but did not read the error code. I had to return couple times, and the service tech finally saw in person when the lights were flashing and was able to use the factory diagnostic scanner to read the error code, C0020-01. This error code directed the tech to replace hydraulic control unit (HCU). "...The replacement procedures says to drive vehicle if code comes back replaced abs module..." From online search, I found out that the replaced HCU in my truck was still XXXXXXXXAA, not XXXXXXXXAB, as shown on the invoice. Therefore, it explained that my truck now has the same ABS/Traction Control light flashing problem while driving or idling only after no more than 13,000 miles after the repair. So no cruise control could be used. I returned to the same dealership today, 1/15/2024. However, the service advisor warned me that I'd have to pay for the diagnostics ($296) that might not guarantee to find the error code since the flashing was not happening in front of the service advisor. I was told that until the flashing became permanent then return like last time. Based on this conversation, I felt that the dealership did not want to take any responsibility. My last paid repair at this dealership would only cover new part and labor for 24-months by the manufacturer, MOPAR, which is about to expire on 4/6/2024. I strongly recommend NHTSA to: 1) require MOPAR or the dealership to have free diagnostics, especially when customer provided video evidences the day before arriving at the dealership for help. 2) recall all ABS & HCU modules in 2018 Ram 2500 Diesel or gas. 3) require MOPAR to reimburse prior repairs nationally for all Ram owners experiencing the same problems prior to Nov 2022. Thank you very much

On October 6th, 2023, my ABS and traction control light began to intermittently come on and turn off. Truck had about 60k miles on it at this time. Problem still persists now at 63k miles and seems to be getting worse. In 5 minutes of driving at freeway speeds, the lights come on and turn off about 20-30 times. I worry that my ABS system is not functioning properly and may result in an accident. Issue has been replicated by technicians at 4 Wheel Parts. Code reader is showing a C0020-01 code is stored in the computer.

ABS and Traction control lights keep going on and off, this still continues and it looks like Ram knows this is a safety issue. Dealers have no parts for repairs

The ABS system is malfunctioning intermitantly. The vehicle can be available upon request. The safefty of any persons in the vehicle are at risk if ths brakes dont work properly. The problem has been diagnosed by an independant service center in Angola Indiana. There are warning lamps on for the ABS and a warning bell as well.

24700 miles is when the Warning lights and chimes started. I went on line and apparently this is a common problem with 2018 Ram Trucks. ABS Warning and "Service Electronic Braking System" Lights are on. Went to dealer (Wilson Jeep Chrysler Dodge Ram) they didn't even look at the Truck or hook it up to Diagnostic. They said it's the Hydraulic Control Unit . Parts are on National Back Order, they know about the problem and their shop as fixed over 60 trucks alone. *Manufacturer as not issued any recalls addressing this issue*

Vehicle's "Service Anti-Lock Brake System" light and warning tone is coming on intermittently. I researched this to a common problem with the Hydraulic Control Unit (failure), which is known by the dealer to be common problem among 2017-2018 Ram trucks. Problem with the original manufacturer of this unit, with no parts available for replacement at this time.

The ABS and traction control has a fault that’s turns off the abs system. It’s been troubleshot to the HCU pump. There are several ram trucks with this issue. Fault code is. C0020-01 ABS pump motor control

The HCU in which controls your ABS and Traction control will malfunction while driving down the road when this happens you have no ABS, traction control or cruise controls. The dealer part is unavailable through the dealer due them saying that they are reviewing it. This is a major safety concern due to the fact if you are traveling and it malfunctions and need to stop quickly you cannot or if it malfunctions and have cruise control set to a speed it will slow you down and can cause an accident. When vehicle was carried to dealer and asked what to do the dealer just said to drive it and don’t follow to close to anyone, that is not the answer that needs to be given.

I own a 2018 Ram 2500 with 104,000 miles. During the period of ownership I have had to replace the ABS/traction control module twice. Each time the repair is over $1,000.00 to have a Ram dealer diagnose and repair my abs brakes. This is a very significant safety issue. Without the ABS system I cannot control this vehicle in an emergency stop situation. You cannot use cruise control. This ongoing issue needs to be investigated and Ram needs to be held accountable for a well known issue.

Constantly throwing ABS code and electronic braking system code, and then, turning off the alerts on dashboard. Many complaints of 2018 models were found online and a class action lawsuit.

Traction control/ABS illuminated on dash board as error codes. When driving at any speed the brakes are grabbing the rotors without touching the pedal. The feel is like tapping on brakes. I've replaced wheel bearing hubs for ABS speed sensors, replaced all speed sensors. Replaced the ABS MODULE and HCU MODULE and to no avail. Chrystler has had the main components on backorder. The error codes are targeting both components ABS and HCU. The Ram community has the same concerns as I do. This issue should be recalled because the ABS and HCU prevent from fish tailing and erratic traction

I purchased my 2018 Ram Power Wagon used in 2020 with only 2300 miles on it. In 2022, I started to have intermittent ABS and traction control lights flashing on and off. I took the truck to the dealership and was informed the HCU was defective and needed to be replaced. The truck was still under warranty and was repaired. In Nov 2023, again the ABS and traction control started flashing. Again I took the the truck to the same dealership for repair. This time, however, I was told the truck in no longer under warranty (timed out, not mileage (26000 miles)) and the part wasn't going to be covered, additionally, was told the HCU part was not available, as it was under engineering re-design. After discussion with the service manager, he agreed that since this is the second occurrence, I wouldn't be charged for the part, just labor for the repair, however, the part wouldn't be available until the spring / summer of 2024! I asked if I could continue to drive the truck while waiting for the part to come in and was told that I wouldn't have anti-lock brakes. Obviously I expressed my concerns about driving the truck and asked if Ram was going to issue a safety recall for the part. I was told no. I am still waiting for the part and refuse to drive the truck in the rain or wet conditions.

2018 ram 2500 under 15k miles. Service ABS light started coming in a few hundred miles ago.

Truck is a 2018 Ram 2500 6.7l Diesel Cummins with ~80,000 miles. ABS System Pump Issue. Began around August of 2023 and randomly shows error codes and warning lamps. It is getting progressively worse/more frequent as of today January 9, 2024. Warnings lights for ABS and Traction Control come on and off during drive cycles randomly. This has made driving in wet or icy conditions dangerous for me and my family due to loss of traction control and the inability for the ABS system to safely stop the truck in wet or icy conditions. Error codes have been confirmed with a code reader "C0020 - ABS Recirculation Pump – General Electrical Failure"

Abs light and message on dash came on indicating electrical abs service needs to be performed. Took it to dealer was told needs abs sensor but they are not available. Vehicle is not safe to drive as brakes will lock up if applied .

ABS Brake system failure. Multiple reports of ‘17-‘18 yr models with exact problems.

ABS module has gone out as it has in almost all of the 2017-2021 ram 2500 with the 6.7 Cummins engine

Intermittent ABS brake failure warnings displayed in the message center and warning lamps, message comes on and off erratically. Speed Control is inoperative when message is displayed. Concern has occurred immediately after starting the vehicle before putting into gear and while driving at any speed. Concern is very erratic, does not usually stay on steady for more then 30 minutes. I have multiple videos of warnings coming on and off. Vehicle is currently at the dealer for repair 1/9/2024. The Ram dealer states the ABS HCU module failed and needs replaced. Dealer indicated this was a common issue with 17/18 model year RAM Heavy Duty's. Obviously erratic operation/function of the ABS could potentially cause dangerous braking conditions especially when loaded or towing.

ABS/TRACTION CONTROL intermittent alarms. Vehicle alarms on and off constantly. Dealership has said they have no fix except replace all ABS electronics for about $4000.00 and can not guaranty it will work. This constant alarm turns off the Cruise control.

Truck throws code C0020-01 and my ABS and traction control lights on dash board start to go in an out. Proposes a HUGE safety risk. Truck has 48,000 miles which puts it out of the warranty that covers this issue. Lots and lots of info online about this being a common issue and RAM has yet to recall it still.

My ABS dash light and traction control light started coming on. Service Antilock Braking System and alternated to Service Electronic Brake System. It would constantly bing and display the ABS light and the Traction Control light

ABS system service light comes on, along with message on dash. When this happens, loss of abs brakes. Took to local dealer, was told faulty abs sensor, but none were available at this time. I have a 2018 Ram 2500 sitting in my driveway because it’s not safe to drive

My truck has an intermittent ABS light along with a traction control light and a message displaying Service antilock brake system and service electronic brake system. these lights also sometimes stay on until the next ignition cycle or even several ignition cycles. it also disables the cruise control as well causing an extreme loss of speed on the highway especially when traveling up steep grades. there were no issues leading to the cause of the lights to come on to my knowledge and i have not visited any sort of dealership or service center regarding this issue nor do i have the time or funds to correct this issue at this time.

After much research and blogs this 2018 2500 diesel turbo has a problem with its antilock braking system module. I have taken it to several places since the light keeps going off and on and have no solutions since this part is on back order. I need to find a solution for this truck. Please advise someone.

Intermittent ABS / traction control light and dinging! 49000 miles. Just like every other person complaining about the same exact issue on 2018s. I’m a disabled vet with a family of four on a single income. I can’t afford a 1200 abs module that lasts only 1-2 years. Clearly this is a major manufacturer issue, experienced by many Americans. This needs to become a recall. This is [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

abs traction control light abs brakes dont work

The ABS controller has been replaced twice and has now gone out again. When this happens it turns off the ABS, traction control and cruise control.

The ABS keeps going off and this is the second time. I read reviews and this is a known issue, that needs to be recalled.

ABS lights go on and the truck chimes sometimes, not all the time. Cruise intermittently does not work as well. This is a well-documented issue online. I took this to the original dealer and he said this is a common problem. Even after getting it fixed, it will occur again. The dealer said it is still supposedly safe to drive, but it is very concerning to see ABS warning lights regularly popping up on my dashboard. Many others have parked their trucks and are not driving them because of this issue.

The abs and traction control keep going in and out and is very unsafe to drive such a large truck. I called dealership and they don’t have the abs module and haven’t had it for over a year. So they know it’s an issue and can’t give us any since manufacturer is at fault. My abs and traction don’t work. Thank you

The Anti-lock Braking System (ABS) and the Hydraulic Control Unit (HCU) issue is present on my vehicle. The problem is intermittent and occurrences cannot be predicted, duration fault varies, sometimes repeatedly cycling fault/no fault/fault etc. When the fault occurs cruise control is either canceled (if active) or not available. Occurs at varios speeds. Please refer to NHTSA's open investigation (NHTSA Action Number: PE22012).

The following messages suddenly came up on my screen. Service electronic braking system, service ABS system. Then the following warning lights came on. Traction control warning, ABS light, tire pressure unavailable, parking sensors unavailable. The cruise control is also unavailable. It is winter here in MN and I thought it would be ok until I get it fixed, I will just use 4 wheel drive. 4 wheel drive is also not available. Am not able to get the vehicle repaired, parts on national back order for months. Do not have a backup vehicle. Have to drive an unsafe vehicle to and from work in winter conditions. Can’t lose my job.

Vehicle showing Electronic Brake System as well as Antilock Brake system and traction control system not working. Pinging all the time, currently 165,000 miles on truck. Same issue was dealt with on 8/15/2020 with 39512 miles on truck. Was an out of pocket expense for $927.10 to fix this very important safety related issue. The cruise control is also affected by these messages and will not work. This is known issue around the country with these trucks and something must be done. If folks don't have money to fix or parts to get fixed we will just drive these safety hazards down the highways and jeopardize ourselves and others. What is your fix to this known problem because you all obviously are not correcting the issue for the known problem.

ABS system fails at randomly disabling the abs brake system and the cruise control.

Anti-lock brake system (ABS) failure for second time in less than 18 months resulting in warning lights on dash, and message for service system. These include the ABS light/traction control unit light turn (warning lights, bells, and verbal system warnings) turn on whenever the truck goes over rough road, bumps, potholes, randomly, as well as starting up truck. The first incident began in July 2022 was brought into the dealer on July 18, 2022 and mileage on truck was 25,121 miles. Dealer diagnosed replaced the anti-lock brake system control unit for brake system and returned truck to me. In November/December 2023, the ABS light and traction control unit lights on dash keep coming on and system says to see dealer. These include the ABS light/traction control unit light turn (warning lights, bells, and verbal system warnings) turn on whenever the truck goes over rough road, bumps, potholes, randomly, as well as starting up truck. It also appears the cruise control will not work if the ABS system is in error. Dropped off at dealer 12/29/2023 and dealer advised that they could not repair at current time due to no parts available and earliest update may be late Jan 2024 if available. The parts that need to be replace per the dealer are the Anti-lock brake system control unit and the ABS module need replacement and no parts were available at the current time (12/29/2023) to repair the truck.

ABS and Stability unit has failed, vehicle has 26160 miles . Dealer and manufacturer know of defect and refuses to provide any fix. This is a serious safety problem, and vehicle is unable to be used .

abs / traction control system failure and cruise control no longer function. This has been intermittent since May, 2023. This became permanent in November, 2023.

ABS/ Traction control indicators intermittently chimes and lights on dash goes on/off while driving over every little bump or pressing/depressing emergency brake My safety and others safety put at risk due to ABS and Traction Control malfunction Problem reproduces everytime vehicle is driven ABS and Traction Control warning lights and messages on display No prior warning lights

My third ABS module failed while towing (aka hydraulic control unit), resulting in a loss of ABS brakes and issues controlling the vehicle and trailer. The truck had 67,000 miles at the time of failure, and all modules have been replaced with OEM components, one of which is at my expense. There is absolutely a known problem with the HCU and Chrysler needs to issue a recall to remedy the issue and reimburse owners who have been forced to repair these vehicles out of pocket.

Hcu system failed now trucks and system is messed up, can’t use cruise control and nervous too drive the truck for safety reasons. Dealer says it could be months for a new system

My antilock braking system is defective and is not working. I understand that this is a common problem with my vehicle. It is a safety related issue and should be recalled. The code reader indicates C002001. Ram TSB S2005000004.

Electronic Barking System. Brake Anti Lock System Frequently Flashes Alarm on dash screen. Yes it's available for inspection upon request Alarm is going off so we are at risk at any time. Seen by Dealer. Diagnostic code DTC C0020-01. Tech verified the DTC is active. Tech has isolated problem to the ABS system. I've read up on this issue it is apparent the is a VERY COMMON ISSUE. Why are there no recalls on this problem?

Service electronic brakes, traction control, and service trailer brakes light stays on.

The ABS module is defective on my truck which controls the antilock brakes, Anti slip function, and the cruise control. Dealer ship has diagnosed problem and ordered parts but the parts have been on back order for quite sometime with no ETA from RAM when parts will be available. My dealer ship says they currently are wating on 25 parts for different vehicles with same problem.

At around 74,000 miles in December of 2023, a warning to "Service Electronic Braking System" and "Service Antilock Brake System" started to show up on the screen of my 2018 Ram 2500 6.7. The truck was taken to a Ram dealership and the fix to the problem was determined to be replacement of the ABS module in addition to replacement of the HCU. Apparently, the ABS module is faulty and is causing the HCU to go bad so both need to be replaced. Replacing only the HCU will not fix the problem. The truck has not yet been repaired as a new ABS module is not available until June of 2024. When driving, the on screen errors come up frequently at all driving speeds and the error is present the majority of the time while driving.

ABS/Traction Control warning alarm constantly going off, and affecting cruise control.

ABS system and traction control lights turn off and on intermittently. ABS pump and module have already been replaced and issue is still happening

ABS intermittently turns off, brought to dealer and advised that ABS control unit and pump need replaced. Also went to service garage with same diagnosis. Dealer advised that the part in question, the ABS hydraulic control unit (HCU) was not available and would be redesigned maybe next year 2024. This problem has persisted since August 2023. It is dangerous to have the brakes compromised and the uncertainty of stopping prowess. The internet is full of identical issues concerning the 2017-2018 Heavy Duty Rams being afflicted with this issue. Chrysler should be accountable.

I'm just reporting the failure of my HRU as many RAM owners have experienced. The dealer ship replaced the part with the new model. When this fails it happened at highway speeds disabling the cruise control while towing a trailer. Becuase of busy traffic and under heavy weight when the truck fell on its face. I was almost rear-ended due to the sudden loss of speed. Very dangerous when towing.

ABS sensor light comes on at random times. My truck just reached 100,000 miles. I've performed no troubleshooting but it is extremely intermittent, either the Service the Automatic or Service the Electronic Braking System(s). Usually, a bump in the road makes it come and another turns it off. Sometimes it happens so quickly, only the message and traction control disabled light comes on, sometimes only the chime comes in. Sometimes the message stays up and the brake warning and traction control light comes on, sometimes for a few minutes, sometimes a couple of seconds. To compound the problem, there appears to be an issue in sourcing replacement parts resulting in a delay in repair. A delay in repair could result in a additional damage to the vehicle, not using the vehicle (not an option) or ultimately an accident.

ABS and traction control light comes up randomly. Sometimes comes on then off with a chime each time rapidly for the entire time the truck is driven. Or the lights will come on and just stay on. At times the brakes become hard to stop the vehicle. Also does not allow the cruise control to work. I use this truck to haul goose neck 8 ton dump trailer and a 36' fifth wheel not knowing if the truck brakes will work is very concerning. Took it to the Ram Dealership and was told needed to replace the ABS pump at $1260. Vehicle only has 63,000 miles.

ABS warning light comes on and message to get ABS serviced appears...took truck to local auto repair and they checked ABS and said ABS module was bad...tried to get part but was told it would be June 2024 ( 6 mos ) before part would be available...was told this was a common problem and it SHOULD be a recall on the module but so far no recall..I got on line and found out that this part is defective and can cause serious brake problems...Class action suit is in the works

At exactly 75100 miles my 2018 Ram 2500 Tradesman gets a warning light to service my anti-lock braking system. Since I was on a trip I also noticed when the warning comes on it also disengages the cruise control. This has been happening for over 1,000 miles and a couple of months. I've tried to look up to see if there's a recall, but there isn't. I do see several hundred posts/complaints online and even other people contacting NHTSB about this issue. My truck seems to be acting fine now, but I haven't had the time to bring it into a dealership since I'm constantly on the road. I have tried to contact a Ram dealership service department, but no help come of it. Since Ram knows about this, they should recall the trucks and fix them.

2018 Ram 2500 ABS hydraulic control unit failure

I purchased the truck used from Kunes dealership in Sterling Illinois with about 80k miles. It shifted harder than I was use to in low gears, right off the bat. I was advised everything was good with it at the oil changes and inspections. In June 2023 I noticed it would not shift into reverse and without yanking in the shifter. It lunges once forward while in park in my driveway. At just over 100k miles the check engine light came on. Coded as needing a new transmission. Also in September 2023 while driving it a brake warning light flickered in and went off. Haven’t seen it again. I think there are problems with this truck. The shifting slow and hard in low gears seemed odd and I worried about proper acceleration to avoid a rear end collision. I understand very little about vehicles but this one has been doing dangerous things that makes me worry about the safety of it.

My ABS and traction control lights come on and off. When the lights are on I have no ABS or cruise control. When the lights turn on and off it's a distraction to my driving. If I am driving with cruise control and the ABS light activates I lose cruise control and have an abrupt decrease in speed. If I brake on a slick surface such as mud without ABS sometimes I skid and my stopping distance is increased.

Abs and traction control malfunction light goes on and off.

ABS/HCU is a known issue for failure. Mine is intermittently flash alerts for service/problems. 1000’s of people are having these issues. Where is the recall? This is a safety issue, is it not.

Failed parts . #1 abs module #2 steering box & intermediate shaft #3 balljoints .available anytime for inspection? # 1 risk brakes locking up or soft pedal #2 steering wheel back and forth to stay on highway #3 knuckle fall off failed balljoint all causing an accident.. all independent shop for all components.

abs pump motor control-general electrical failure Going down the road it will flash service abs brake failure( something to that effect) then instrument lights abs, traction control come on with constant chime beeping. If you are on cruise control it will quit.. also abs and traction control don't work and will not engage.Not very safe to drive in wet conditions. Took to dealer ( code 45806) and person pulled code dtc C0020-01 stored abs pump motor control-general electrical failure. Was told need up to 5 days to diagnose problem and with holidays I will wait til after Jan 1 to take it in. Problem comes and goes but will come on everytime I drive it then after a restart it might go away. Dealer visit was 12-18-2023 time 12:41 pm dealer code 45806 will have the info.

Got a code for service abs system, abs module pump bad. Ram cannot even get people in to fix the issue and they want like 2000 dollars out the door to fix this unsafe issue. I also have no cruise control now and no abs. This is an absolute shame that my truck only has 66k mostly highway miles and is now worthless because I cannot afford to fix it. Ram will not fix this issue under warranty. There is a current lawsuit under James Neu vs. Fiat Chrysler to get them to make this a warranty issue and fix it. Please please please release the recall so we can get our trucks fixed! Thousands of trucks are affected and at risk of accident. Thankyou please let me know if there is any hope in the future of this recall. I don’t know if I should just wait it out or get rid of the truck [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ABS HCU and control module repeat failures. Initial failure when vehicle purchased 12/20/19 (repaired by warranty replacement on 2/25/2020 @625 miles of the HCU and ABS control module). Current failure 12/18/2023 @ 6300 miles.) So the failure problem is recurrent. Failures are intermittent and cause deactivation of the ABS, ESC, and Cruise control systems. This results in sudden change (slowing) of vehicle speed upon cruise deactivation. Also the loss of ABS and ESC can be hazardous depending upon roadway conditions and vehicle operation at time of failures. Failures can persist for days or perhaps subside for a brief time. This vehicle problem apparently exists on more than one 2018 2500 RAM. When at the dealer for first failure repair, two other 2018 RAM 2500's were in service for the exact same issues. Also, replacement parts are back ordered taking months to arrive. Thank you. Very Truly, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

brake warning light flashes warning alarm sounds. . disables the trailer brake. this one safety concern and makes my vehicle unavailable for towing abs disabled as well. Dealers says HCU is suspected . Parts are not readily available.

2018 Dodge Ram 2500. I have been working with the dealer to have the ABS module repaired for over 6 months. All 2017 and 2018 2500 and 3500 are having issues with the ABS module not working properly. The dodge representative said there is not a fix and does not know when one will be available.

The "Check Antilock Brake" message appears on the dashboard. The vehicle has been inspected by a mechanic who confirmed that it is either the supplementary brake fluid pump, or the brake pump control unit. Because of the intermittent nature of the problem, the manufacturer requires replacement of both expensive parts, as they do not know the exact problem. Because of the issue, the following vehicle features do not function: * anti-lock brake system * electronic stability control / traction control * cruise control * the holding of the rear brake on a hill until the operator accelerates (important in a standard transmission truck used for towing)

As with thousands of other owners with this model of truck my anti-lock control module is bad. The malfunction causes the anti-lock brakes service light as well as the traction control service light to be on. This malfunction renders both systems to be inoperable, thus causing a major safety concern.

Originally I started feeling like my brakes weren't stopping as well as they had been. The pedal seemed to feel soft and have further travel than normal. I recently had my brakes inspected by a certified mechanic, so I was confident it wasn't the actual brake pads, rotors, or calipers. After a day of this I started getting intermittent ABS system and traction control lights. About a day or two later the lights became more frequent until they eventually stayed on. During that time I was out of town while pulling my fifth wheel camper, so I wasn't in a good position to get the truck to a mechanic. Needless to say I felt my situation was becoming unsafe. Once I returned home I got the truck in to my mechanic and his troubleshooting led to a faulty ABS module and Hydraulic Control Unit. This was a very expensive repair. Once I was told what the diagnosis was I started to research this issue online. This is when I discovered that others were having this same issue and that the NHTSA had already opened up an investigation into this.

Error code saying "Service Electronic Braking System" and anti skid brake stop working and crash avoidance braking (rear ending someone) stops working. Dodge is saying no replacement until March 2024. There is a recall to fix 2019 and newer so not sure why 2018 was excluded from this recall to fix a serious safety malfunction in the braking system.

Abs light and traction control light will flash and beep intermittently when driving have researched a lot of people have the same issue newer models have been recalled for the same problem.

The ABS failed at 34k miles. The ABS and/or traction control lights turn on intermittently while driving. Using a scanner I see Code C0020-01 ABS Pump Motor Control Electrical Failure. I called dealerships and many online vendors and parts are on national backorder 1yr. I don't let the family ride in my truck anymore due to safety concerns. Even a slight touch of the brakes and my truck skids. It's wet and cold here in Seattle making it even more dangerous.

ABS/Traction Control dash light comes on and off randomly all the time. The sound is infuriating and kicks off cruise control. Today I came over a hill on highway and there were cars stopped in all lanes ahead. I stepped on the brakes hard and the abs didn't work causing the tires to lock up. I did not hear or feel the normal pulsing in the pedal. I feel there is an actual problem with the abs system and not just an annoying chime and light on the dash. There are thousands of threads about this problem online and I feel that it is cause for a recall. I checked with local dealer and the parts are extremely limited supply because of all the people with the same problem.

ABS Warning light and alarm tone keep coming on when driving. This seems to be a common problem w/ this year and style truck.

ABS & traction control lights on along with messages reading "Service Antilock braking system and Service Electronic Braking System. 1st intermittently then very often. Code C0020-01 is stored in the system via OBDII scanner. It is available for inspection at any time. I can not tow anything that requires trailer brakes because I here, through many other online complaints that trailer braking will be inhibited. I have not yet taken it to the dealer yet because it is out of warranty and the part required to fix it properly won't be built/available until Feb 2024. I first saw warning lights/messages in July of this year 2023 with around 37,000 miles. See attached pics.

Bought vehicle used in August 2022. In August 2023, started getting intermittent chime, abs and brake warning lights and messages to service anti-lock brake system and to service electronic brake system. Took it to my mechanic and he diagnosed a bad abs control module and bad abs hydraulic pump fault codes. He did some research and found this to be a known problem with these trucks. Apparently Stelantis is working the problem but no fix. My mechanic doesn't want to replace the parts for fear the replacement parts are bad too, so I'm living with the problem. He said in the mean time, be aware I have no anti-lock brakes and no cruise control.

ABS Service Light and warning bell keep coming on. I've had this fixed twice and appears looking at forums that investigation is under way as part is failing on most all 2017-18 Ram 2500 trucks. Please make Dodge to replace under recall.

The ABS and Traction Control lights flash and ding on/off intermittently. Sometimes the lights on the dashboard come on as soon as I leave the driveway and sometimes it takes several miles. But once they flash on and ding on the dashboard, the lights flash on and off intermittently for seemingly no reason at all. I am not sure if this is due to an electrical issue, a hydraulic control unit issue, or something else, but something is not right, making the lights and dashboard flash/ding a lot.

The ABS and Traction control lamp keep flashing on and off intermittently. When those warning lights are not lit up, I can use the truck normally. However when they do light up cruise control no longer functions. I have not tested if ABS or Traction Control is not functioning, but I am not going to take a chance. This endangered my family, and surrounding drivers as I was towing our trailer on the freeway and had set the cruise control. In the middle of the drive, the warning lights came on, and the cruise control turned off by itself. At the time we were climbing up a grade, so the truck slowed down rapidly. The Semi-Truck behind almost crashed into me as I tried to determine if I had an engine failure, and deciding if I had to pull over. They honked at me repeatedly. I determined that it was not an engine failure and I could increase speed. By then the truck was below 30 mph. I may have caused more catastrophic issues behind me but, I could not see past the 5th truck behind me. My wife was screaming at me to pull over, and was upset that the vehicle was not working. It works, but the brakes are not dependable for ABS, and cruise control is not dependable. I drove the vehicle several times since and the issue keeps occurring. I have not taken it to a dealership, and do not drive the vehicle anymore at this point. The vehicle has not been inspected as that would require driving it to be inspected. The ABS and Traction Control warning lamps started to illuminate around November of 2022. That was the only indication that something was wrong. I was going to take it to the dealership but it is out of warranty. It drives fine otherwise when the lamp is lit, and it does goes on and off with a dinging sound, but I could not tell that anything was not working. It was not until the incident with the cruise control that I realized it impacted the ability for the cruise control, and that it would turn it off when I am using it. It is completely random.

The ABS-HCU is defective causing a loss of the safety aspects of it purposes, Constant warning alarm and flashing screen.The parts to repair are not available. My dealer is not optimistic of the part replacement correcting the problem, it might be the Electronic Braking module, got an additional fee. The dealer would not say it was safe to operate but advised against towing I stated that was the purpose of the truck.

Issue with ABS and HCU. Known issue with Ram trucks but no recall for 2018. "Service Electronic Brake System" warning comes on and off constantly.

ABS electronic braking system failure.

While driving with cruise control activated the Service ABS light came on and made an audible ding and the cruise control deactivated resulting in a loss of speed traveling along an interstate highway. This has happened several times, and no time frame to get fixed.

Abs control module had went out twice in 3 years and hydrolic unit causing brakes to fail

This truck has just over 40k miles and the hydraulic control unit and the anti-lock brake system module has failed 3 times. The first failure was at 28k miles, the second failure was at 36k miles, and the third failure was at 40k miles. When the systems fail ABS, Traction Control, and Cruise Control are all disabled. The problem is easily reproducible by the dealer, and at the 3 RAM dealerships I have been to, the service managers all say this is a problem that plagues all 2017-2018 RAM 2500 and 2018-2019 RAM 3500 trucks. If you at any of the RAM forums or Facebook groups you will see this is a very common failure that leaves the owner without ABS or Traction Control, which is very dangerous when using the truck for its intended purpose (hauling trailers). This problem is so common that the part is commonly on backorder for 3-6 months. When I went to the dealer after my latest failure in Nov 2023, I was told the part would not be available until sometime in the summer of 2024. The the failure occurs the ABS and Traction Control Light come on, and you get a message that says "Service Electronic Braking System". RAM really needs to redesign the part(s) and issue a recall for this. The contact stated that the vehicle has yet to be repaired.

ABS warning light comes on and off again. Each time it comes on, the cruise control turns off. This continues to happen -- going on and off. This is unsafe as the trucks cruise control stops functioning without warning.

ABS module failure preventing appropriate operation of the ABS and traction control systems. Ongoing problem for multiple months/years

Traction control and abs warning lights flash on and off intermittently also cruise control not working when this happens. It is sporadic

The truck randomly started flashing service electrical anti skid braking system. It will go on and off randomly and other times stay on all the time. It will not allow cruise control to work and I’m guess my ABS will not work either if I need it. I bought the truck with 132K miles on it and the light starting coming on at 134K miles. I don’t want to possibly injury others or myself is the ABS does not work. I took it to the dealership and the light went out and they couldn’t see any codes. The light is back and almost always on. Going to take it back to the dealership. To see if they know what is wrong since this is a known issue with most Ram trucks.

Intermittent “service brake system” comes on. Spoke to dealership and said they do not have the part to fix the brake system. It is on back order being “re-engineered” and have no indication when it will become available.

On 15 Nov 2023, my ABS and Traction Control warning lights illuminated. I took my 2018 RAM 2500 Tradesman Diesel truck to my servicing dealership (Fayetteville Dodge Ram, Fayetteville, NC) that afternoon and was told I needed to replace the ABS Module (Mopar OEM 68347098AB) and Hydraulic Control Unit HCU (Mopar OEM 68143491AB) . The dealership's parts department told me there was a backorder of about 4,000 of these parts nationwide. I attempted to obtain these parts through Mopar Parts Overstock and was told the same thing. After many internet searches, I find that this issue is wide-spread and potentially dangerous. I am now driving my truck with this brake defect, although my dealership assures me the braking system is safe to operate. Why is there not a recall on this wide-spread issue?

The truck intermittently shows an alarm for failure of the abs braking system. This suddenly shuts off the cruse control and disables the abs. The loss of cruse control caused the truck to suddenly drop in speed in a highway traffic situation, which nearly caused a car behind me to hit me. The loss of abs leaves the truck vulnerable to brake related accidents in slippery or wet weather. I contacted a dealer for the replacement parts and they told me they would not be available until a new generation of abs module and hydraulic control unit were available. I believe the NHTSA should demand a recall for this extensive and dangerous issue.

Twice the ABS hydraulic control unit has become faulty and no unavailability of parts. The “issued warning” from Chrysler corp is be weary as the truck no longer has cruise control, 4 wheel drive, and a warning light and audible alarm that comes and goes to on/off every two to three seconds causing an immense amount of mental irritation while driving. This vehicle has been looked at twice by dealerships have diagnosed and also charged me every time to hook up to their diagnoses (around 200$). I have called RAM cares who is nothing more the a shell of the company to appear as though they care but of are little to no help. So recap, I have a ($60,000) truck that is the equivalent of a base model s10 ($15,000)(basic model truck) because one part has made it impossible to use the truck in its fully designed capacity. No four wheel drive, no cruise control, and a dinging and flashing light that happens every 2 seconds and a message that say service electronic braking system. I would upload a video but you can literally google “HCU ram 2500 problem” and a slew of videos will pop up. Maybe someone at either this organization or Chrysler will actually care and start holding people responsible for this problem and issuing a [XXX] fix.

Warning Lights for "Service Electronic Braking System" and "Service Antilock Brake System" come on and off indicating repairs to module necssary; however, Ram/Dodge can't schedule repairs for over a year in most locations. This is an ongoing problem and it appears to be affecting thousands of owners of Ram pickups. The code is C0020-001. The ABS/Traction control light comes on - a message to service the Anti-Lock braking system comes on - and the cruise control does not work. This happens intermittently sometimes several times in a minute, sometimes it's several times a day and sometimes it will stop for 2 or 3 days without the warning lights coming on at all. It's very frustrating and unnerving as the cruise control just drops out while you're driving which is not safe. The ABS also does not function with this issue. This issue needs to be addressed. Additionally Ram/Dodge dealers indicate this is a well known problem and that there are parts shortages for this repair due to the amount of Ram pickups having this issue, the parts are in short supply with everyone needing to make this repair. Please require Ram issue a recall. This is not safe.

My ABS module and HCU are acting up. Warning lights on dash keeping going on and off intermittently stating service Anti Lock Brake system and Service Electronic Braking System. Traction Control loss warning light accompanies these lights. I have had the module replaced twice already and still not working. Was told yesterday (Dec 07,2023) by warrant repair facility that there is a new upgraded part available and to file a complaint. These problems started in October of 2023.

ABS control module failure leading to loss of anti-lock brakes. The vehicle is available for inspection. Yes, the truck has become uncontrollable under emergency braking situations. Yes, the problem was confirmed by the dealer, but there is apparently no remedy available for at least another year. This is the second time the ABS/HCU module has failed. The first instance was fixed by the dealer in 2021. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others. The warning lamps first appeared when emergency braking. They are now intermittent, with no consistency as to whether the ABS system is active or not.

The “Service anti-lock brakes” indicator comes on constantly. It is unknown whether there is a problem with the brakes. The replacement part is on back order and appears to be months behind

2018 Ram with brake module problems. In September 2022, warning lights came on stating that the antilock brake system and electronic brake system were failing. At this time the problem was known to the dealership and parts were found and replaced under my extended service contract. Parts replaced were the: Module, Anti-Lock Brake(68347098AB) and the Control, Anti-Lock Brake System(98143491AA). Replacement was done at Payne Chrysler Dodge Jeep Ram Edinburg with Mopar parts. Replacement was done September 15th, 2022 service repair order #565792. Mileage at the time of repair was 38,538. On November 5th, 2023 the exact same symptoms appeared. On November 28th, the truck was diagnosed at Payne CPDJR with needing the exact same parts replaced. Mileage at this point was 41,998. Clearly, this is a serious problem if the exact same parts need to be replaced after less than 4,000 miles. This is obviously a dangerous and ongoing issue that needs to be addressed. I have been advised not to take the truck outside the local area until repairs are effected. I have a truck because we live on the road full time and use it to tow our 5th wheel(total weight is 9,800 pounds fully loaded which is easily within the trucks towing capability). As of today, December 8, 2023 I was advised that the parts were at least 2 weeks out. I contacted Chrysler customer care and opened a complaint. When the modules show failure, the cruise control is inoperative and it is advised to take the truck into a dealership immediately. Someone needs to make FCA step up and take responsibility for this clear disregard for customer safety, by ensuring that these parts are reliable and available if needed. Having to replace the exact same parts twice shows a clear disregard for quality control and vehicle safety especially when these parts are going to take a month for the dealership to receive.

My ABS and Traction Control lights keep coming on and cruise control will not work when the lights are on. This has been occurring for the past few years. The lights are on most of the time and I’m afraid my abs breaks will not work properly especially when i’m pulling a trailer. This is an ongoing problem with 2018 Ram 2500s. Ram needs to remedy this problem.

ABS Module Failure. Truck is available for inspection upon request. The ABS Module Failure directly effects the safety of all occupants and other vehicles on the road if not able to stop as intended to. The problem is confirmed by a dealer. There were no warning lamps until the ABS Module failed and needs to be replaced. This is a standard issue that needs to be recalled.

My ABS System has failed and will not operate whiteout changing the ABS Module and the Hydraulic Control Unit. These units are not available and when they are available fail again when install. Need a recall from Dodge on this issue.

Warnings About Service Electronic Brake System. (ABS and Traction control lamps light), system audible pings. Issue where system continues to show, ping for this issue. RAM is aware of these issues and will not provide parts. Concerned about safety, brakes seem to work fine, just unsure.

Abs module is out again. Second time in just over a year since I replaced it last time. This is an ongoing issue and numerous people locally are complaining, so national has to be thousands. Ram is aware of the issue but not fixing.

My ABS module is faulty and there are no available replacements. RAM is aware of this issue when I called my dealership and they have no solution. The ABS is all screwed up and people are reporting this all over the internet. RAM needs to address this situation with their customers and fix the faulty ABS repair module.

I just bought a 2018 ram 2500 tradesman yesterday and had the abs light came on today and stayed on. Read comments online and was advise to report this issue as a safety issue and possible class action law suit potential. Seems like many people have the same issue even with a barely use vehicle.

ABS/Traction Control Module failed. 2019-2021 trucks recalled but 2015-2018 trucks with same issue not recalled. Started having issues first in a rain storm towing 32 foot camper with family on board. Cost me $760 to repair at Montrose Jeep Dodge Ram in Kingsville, Ohio.

ABS light and traction control warning on dash. Truck has been in shop previously for the same issue. This causes my truck to lose cruise control at highway speeds and to not have traction control capabilities when driving on wet roads. I will be taking the truck back in to the shop this week as this is occurring at all times and does not stop dinging.

ABS and traction control lights are on, scanned and got code c002-01. Unsure if system is working. Verified by shop, needs a new hcu but none available to fix, no time line on when parts will be available.

Brake service message lights on. Many others with same problems

ABS and traction control intermittently shows a warning light. This may not happen at all while driving or it may happen a few times or constantly. When this happens it disables the cruise control without warning.

Abs and traction control not working, told it’s the hcu due too problematic oem parts

ABS and traction control light are intermittently flashing.

Service electronic braking system on dash with ABS turned off. diesel shop informed me it is probably a failed ABS HCU. they said it is a common problem on these trucks

The Asb light comes on when pushing the breaks and when hinting a bump it is hard to stop .

Abs control module and pump have failed

ABS AND SKID CONTROL WARNING LIGHTS CONSTANTLY COMING ON AND OFF FOR NO REASON. HAD CHECKED OUT AND RECOMMENDED A REPLACEMENT MODELER, AT MY COST. TRUCK DOES NOT EVEN HAVE 30,000 MILES YET. IT NEEDS TO BE A RECALL ON THIS.

ABS and Traction control lights on dash light up sporadically (dings on and off continuously) and cruise control suddenly turns off. No warning and can be completely random. This is part of the ABS pump control module issue commonly reported but no recall. Attempted to have it repaired, multiple parts have been tried (used and remanufactured, because not new parts are available.

ABS and/or traction control lights turning on intermittently while driving, This is the 3rd time it has happened to me on this truck.

ABS traction control problem light comes on intermittently while driving. Cruise control will disengage when ABS traction control light is activated. The ABS traction control light is activating more often while driving.

Had brake module replaced under warranty at the dealer and less than 10k miles later it’s doing the exact same thing again. Abs is not working, alarm constantly chiming while driving and abs and electronic brake malfunction lights coming on in the dash. Truck still has less than 48,000 miles on it cause I’m scared for my family’s safety so we just don’t drive it anymore. Is a shame we have a truck we can’t use that we have paid for for this long and still can’t use due to a safety concern that the dealer won’t repair again cause the time limit has expired on the parts warranty.

Service abs system immediately popped up on information screen, also abs and traction control lights all at the same time. This disengages cruise control and removes digital speed reading. Almost got tailgated.

Purchased truck and abs light is on that disables abs and traction control. Which in turn won’t let you use cruise control

Random ABS and service traction control system lights displayed on the dash. Dealer troubleshot and found that the ABS module and Hydraulic control unit (HCU) need replaced. This is a common issue based on the dealers comments and ram does not have an adequate fix for the issue, only replacing components to see future failures. This needs to be handled, as it deactivates the ABS system and may cause issues in the event of a hard braking condition.

This is my 4th HCU/ABS Failure. 3 Priors were replaced/reported in FEB/March to NHTSA. ABS / HCU System Failed. My safety was directly impacted. Various warnings and lights on the dash lit up with "Service Electronic Braking System". When the ABS / HCU system has an issue, it deactivates the cruise control, ABS System, traction control, and parking detection system. This can cause a sudden and unexpected deceleration or loss of vehicle control, as the traction control system also shuts off without warning. The dealer is able to verify the issue. I have taken the truck to the dealer, who is reporting a part shortage and multi-month backorder for the part. This is a huge safety issue, and could have killed me and my children. This should become an immediate recall since it directly impacts the safety features of the vehicle as well as the cruise control system, which may suddenly deactivate and cause sudden deceleration. Various warning lamps display. BRAKE, ABS, Traction CONTROL.

This vehicle has failure of the ABS module and the ABS HCU. This is due to a manufacturing default. This causes the APS and traction light to come on the dash along with service electric brake system in the message center. At this time on 11 -24-2023 this is such a big issue you are unable to get the parts to repair the vehicle and there is over 3,600 units on backorder when you contact dealers. Because of the failure this prevents safe breaking of the vehicle

ABS light and Traction Control service alert light on dashboard. Second time this has happened. I had this issue prior and had Ram replace both parts that needed to fixed and was not covered by Ram. This/ these are faulty parts and Ram needs a recall. There are thousands of Ram owners that have the same issue and Ram refuses to acknowledge and recall these parts/ issues! Please help us!

C0020 - ABS Teves/TRW Recirculation Pump General Electric Failure Error Intermittent. Approx. Dated Occured Nov. 15 2023. ABS Module and Traction control goes off-line intermittently during drive tests effecting ones ability to stop safely and prevents ABS pulsating Hydraulic braking when towing locking up vehicle brakes effecting driver and adjacent traffic/pedestrian safety. Vehicle is currently being serviced by an independent dealer but I have managed to replicate the issue on test drives and error is logged as a permanent code within the OBD II ECU Ram Module confirmed by Autel System. Warning lights did appear when or at the moment the system failed not prior.

I own and drive a 2018 Ram 2500. This morning on the way to work the "Service Antilock Brake System" & "Service Electronic Braking System" error messages are popping up on the dash on and off. This is the 3rd time I have received this problem and the truck only has 42,200 miles on it. The first time the dealer replaced the ABS module and HCU at only 15,486 miles. The second time the dealer forced me to pay for these parts knowing that this is a manufacturer defect and a widely known issue. When this happens the trucks ABS system and traction control does not function properly posing a huge safety risk! I don't know if my trucks brakes will work properly, are reliable or if I can even drive it. I am now forced to rent a car until something is done about this. This issue has been reported many times over and is wide spread all over social media. It affects thousands of people that own these trucks from 2017 to 2018. failure TSB Number: S2005000004 and NHTSA Action Number: PE22012

Intermittent ABS / traction control light diagnosed as the ABS / hydraulic control unit. I see this is a very common issue and very dangerous.

Anti-lock brake system module is out causing hard brakes and pulling which could cause a wreck. This is a known problem and has been reported by many 18 Ram 2500 owners. My truck is not safe in this condition and there needs to be a recall to make these trucks safe.

The ABS and HCU are bad in my vehicle. It appears to be a widespread issue with this year model. A recall should be issued by the manufacturer to correct this safety issue. I recently collided with a barrier wall because my ABS system was not functional.

Abs module failed for the second time. Braking is not predictable without abs system

Truck has 15500 miles on it. ABS and electronic braking system light comes on and off randomly. Causing me to lose traction control, cruise control and ABS

the abs and traction control keep lighting up and lose both while driving.

The ABS and Traction Control System light and warning engage intermittently when operating. The alarm startles the driver and unsure if system works

After a hard braking event Service Electronic Braking System and ABS warning CEL came on. Goes on and off intermittently sometimes 20-30 times in a mile of driving.

"Service Antilock Brake System" & "Service Electronic Braking System" error messages are popping up on the dash on and off while truck is running. Sometimes pop on after starting the vehicle while sitting in drive and other times while driving.

Loss of ABS. The hydraulic abs unit failed they are on nation wide back order cannot get them. 2018 are not recalled yet only 19 and newer have been recalled for this issue. Truck losses abs and due to that losses traction control. Very common issue in all 2018 ram 2500. Very dangerous to drive a big heavy duty truck with no abs.

Truck has 26xxx miles on it. ABS and electronic braking system light comes on and off randomly. Causing me to lose traction control, cruise control and ABS. Dodge dealership run diagnostic on it and stated it has a bad HCU. Their are currently about 400k trucks with this same issue. Dodge is aware of the problem and the safety hazard of this issue. Dodge refuses to issue a recall. Cost to repair is $1000. Please force dodge to issue a recall and take responsibility for this mechanical failure

Abs module and can't replace because back ordered

This vehicle has had a recall on ABS module and HCU for ABS. The replacement is now repeating the same issues as the original within a few miles. (Service ABS, traction control, and various other lights flash intermittently, causing the cruise control to turn off suddenly, which represents a huge danger.) Not to mention the constant bells and whistles being distracting.

ABS and traction control indicator lights start flashing and became intermittent during a road trip. I took to dealer and they replaced the abs motor pump and controller this happen 11/21 and after the warranty expired. 3 months ago it flashed a couple of times and now is flashing intermittently each day and will cost another $1600 to replace. The code is C0020-01 and is attached. This happens about 1 min after I start the engine, goes away for a few minutes until I hit some bump in the road and it triggers.

During normal operation the ABS, Traction control and electronic braking system warning lights came on. Now when i am driving the Service electronic braking system lights will come on and off intermittently. Some times if i hit a bump it will come on briefly. My cruise control does not work and from what I've read my 4 wheel drive may not work. I live in the snow belt and use this truck as primary transportation as well as plowing snow and for our business. Im told this can be a brake module. I only have 40000 miles on my 2018 ram big horn. should not be having these safety problems.

warning lamp repeadly blinds on dashboard to service abs brake system. turns out this is a common problem with the ram abs control module going bad. this is confirmed by dodge dealership and there's a long waiting list for the replacement part. driving with afaulty abs module results in poor braking performance.

While normal driving of my 2018 Ram 2500, I began to get random audible warnings, service anti-lock brake and service traction control system dash lights. The lights would flicker on and off and warning chime would 'bing" numerous times. This caused the cruise control to shut off while doing 65mph. Some drives I would get nothing, others would be a solid 5 minutes of flashing and chiming. Scan tool identified the C0020-01 DTC. ABS pump motor control general electrical failure. Appointment was made at local RAM dealer and I was told that the parts are unavailable and on national backorder. I am now uncertain driving the truck as I do not know if the brakes could go out randomly or fail completely. Upon researching this fault, it seems to be a very common issue with the 2018 Ram trucks.

Anti=Lock Brake System- Hydraulic Control Unit. I bought this truck new. HCU has already been replaced once while truck was under warranty. Unit has failed again. I have been driving and trailering with a faulted ABS system since 10/22. Been to dealer for repair. No replacement units available.????? And it is constantly ding donging on/off as it faults. Can not trade it in with the fault. 70k$$$ truck! They should buy it back if they cant provide a solution or parts. And they expect me to pay for it if it is repaired a second time. Said 1st replacement warranty ended with the truck warranty. I have worked for a top automotive fuel injector/ABS Module manufacturer for the past 28yrs and I can tell you- This Is Not Acceptable.

Anti-lock brake / traction control lights come with audible chime. Message reads service anti-lock brakes and service electronic brakes. Problem is intermittent with light coming on for a duration then going out and clearing message center. At times, the warning lights turn on and off rapidly giving multiple audible tones. Activation of light causes deactivation of cruise control. At highway speeds - rapid deceleration occurs. Unknown if the anti-lock brake or traction control will function while light is on. This will be the second time this issue has occurred. First time repair was covered under warranty for same issue. Diagnostic’s performed at authorized Ram dealer (10/27/2023) (Approx. 48500 mile's) indicates issue with Anti-lock brake control and Anti-lock brake module. Remedy - replace defective parts with: 68143491AB Control: Anti-Lock Brake 68347098AB Module: Anti-lock brake Total cost to repair: 1478.25 Dealer states that no factory warranty on this repair. Parts not available until February 21st 2024

While driving the truck my ABS, Traction Control and red brake symbol come on the dash as a warning. The vehicle once this happens no longer can utilize cruise control nor its ABS system during hard braking. This problem began intermittently and has become permanent. Dealerships are unable to get parts for repair.

I was driving my vehicle and a car in front of me stopped at a traffic light. I attempted to brake my truck to stop the vehicle and I only had limited braking power and hit the vehicle n front of me. I had been experiencing intermittent ABS and Traction Control lights and I had a mechanic check all the wheel sensors and replaced one sensor that was damaged when the sensors were checked and cleaned. I had no indicator lights on prior to the crash and the ABS and Traction Control lights were illuminated after the crash. This was verified by the officer onsite at the crash.

ABS control module is bad. Makes abs and traction control lights blink on and off erratically. Have had it replaced over a year ago under warranty for the same problem. Now it's doing it again and was told part wasn't going to be available tell February of 2024.

ABS and Traction Control lights coming on at random times. With Code C0020-01 Failure in pump motor control circuit.

ABS light comes on and off constant. Service abs system, service electronic braking system. Ram came up with the code HCU hydraulic control unit failure. They will not fix it unless I come up with the 1500$$ to fix it out of pocket. My truck just turned over 60k this is ridiculous. Go on google and please type this in. It a massive issue in all 2018 rams. Should be a recall at this point. If you guys can fast forward me to get repaired please let me know I feel as if this could cause harm if the brakes lock up or I get in a skid situation if could cause harm to myself or others or properties. Please call if we can nip this in the bud. [XXX] . Thank you to whom will be reading this and I really look forward to hearing from you. I honestly can’t afford to just dish this out of pocket cost for something that should be under warranty. 😞 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2018 Dodge Ram 2500 with Cummings. My dashboard Anti-Lock Brake lights flash on and off and sometimes stays on and always turns off my cruise control. I’ve called the Ram dealers and they tell me the Anti-lock Brake System Module is on back order till next year. I’m nervous about my life and others on the highway who are driving with me. Can you HELP me. I have not been involved in a car accident yet but easily can happen [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Intermittent dash flashing of ABS and "service electronic brakes" messages tied to known HCU/ABS module fault/failure. C002-01 code. Driving over light bumps trigger lights on/off. Dealership told me to ignore lights and code.

REPEATED SERVICE BRAKING SYSTEM WARNINGS. KNOW ISSUE FOR ABS with these vehicles. Code C0020- ABS pump motor controler.

When I had to use excessive pressure on brakes, I received a DTC and a messaged flashed on my display to service ABS system as well as TCS. I had the DTC read which showed C0020-01 ABS Pump Motor Control General Electrical. It was cleared but when I drove over a speed bump at my kids' school, the same message displays. The message has also displayed during wet weather and minor wheel spin (over white painted crosswalk lines) from a stop. I spoke to a technician from the Chrysler dealership and was informed this has become common and to file a concern here.

2017 & 2018 Ram trucks have have a lot of ABS brake failures. I only have 30,000 miles on my truck. At 22,000 miles I had a ABS module replaced. Now at 30,000 miles I need another ABS module replaced. The problem is Ram does not have any ABA modules available. I am hearing they might have some by March. According to the Ram dealer, Ram is designing a new one because of all the failures. So that leaves a lot of Ram trucks on the road without ABS braking. Not a good thing to happen with winter coming on. Someone needs to address this problem with Ram. Thanks

Hydraulic control unit failed causing abs and traction control lights to intermittently flash on and off. Dealer says replacement parts are discontinued and not available until at least February.

My truck was repaired in September of 2021 at a dealership due to a faulty HCU for the ABS system. I got a famed Ram service electronic braking system message along with service ABS system. After being replaced, I now again as of three weeks ago (10-21-2023) have the same service electronic braking system message with an electrical fault code for the HCU. After visiting the dealership, I was told there were not parts to replace it at this time and they could do nothing for me. Also, my service rep stated that Stellantis is reengineering the part due to known faulty problems however time frame is unknown. With this light on I have no ABS, no traction control, and no cruise control. The no ABS and traction control is a major issue for a heavy duty truck especially while pulling a trailer as brakes can now lock up due to no ABS control. This is obviously a safety issue and I'd hope this would become a recall and quality safe parts would be utilized to fix it.

Truck has 44,945 miles on it and began showing intermittent ABS and Traction Control lights on the dash. This is a known problem on RAM trucks which the ABS module or the Hydraulic Control Unit needs to be replaced. I have noticed lack of braking power when this fault appears on the dash. Both while pulling a 9,000 lb RV and without pulling anything. The vehicle scan showed a C0020-1 ABS (Anti-lock Braking System) Pump Motor - General Electrical Failure.

ABS Brake control warnings have been flashing on and off for many weeks. Took it to the dealer that sold me the truck and they said that they cannot get the parts and it may take several months or longer. I did some online reading in RAM truck forums and this is an ongoing problem for many 2018 RAM truck owners. Some have been waiting over 5 months to have the ABS control modules replaced and all of us are having to drive an unsafe vehicle while waiting.

Service ABS light comes off and on sporadically. This is a known problem through out the country and needs to be addressed by a recall.

Trucks and electronic braking and traction control randomly quits working.

Vehicle started flashing “Service ABS Braking System” and “Service Electronic Braking System” intermittently. There is no rhyme or reason and no way to make vehicle reproduce this at will.

My Ram has about 31,000 and about 5,000 miles ago it kept randomly giving me a message to service the abs system and traction control message. I took it to the dealership and they informed me that it's a common occurrence for my model truck and they replaced the abs module with the same part number and said they're working on a revised part to replace it. They told me that the abs is not working all the time because faulty part which seems like a safety issue. I did some research online and a lot people are having the same issue and are waiting for the new part which is said to be available sometime next year but we will most likely be forced to pay for the new part and labor. Hopefully you will be able to get them to do a recall for this issue. Thanks

The Hydraulic Control Unit Chrysler part number 68143491AA failed and been replaced multiply times on my vehicle. I have the current failed part available for inspection upon request. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. The problem has been reproduced by my local dealer twice both with the original part and its' replacements. I am adding the first date below. The second failure was 12,000 miles later after the first was ABS was fixed. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. There were no Warning lamps/messaged before failure only after. These would be ABS lamp and traction control lamp plus a service ABS warning message.

Automatic brake system module, HCU abs pump. SAFETY. malfunction of part. Known to be world wide problem. Confirm by dealer scanner code. Continuously, warning light and alarm. Response from dealer manufacturers of 2018 ram 2500 diesel, known problem, no recall. Dealer for part can not give time, date when part can become available. Can not give time or date when part will be available?

Anti-lock braking system rendered inoperable by defect hydraulic control unit. ABS inoperative, frequent audible alarms and flashing lights on dash. Dealer explained that problem is common and that replacement part is not available until May of 2024 at the earliest. This vehicle should be recalled. Federally mandated ABS is inoperative and cannot be fixed for at least six months. This vehicle is my daily transportation. Dealer told me that I'll "have to deal with it" till parts become available. Vehicle almost left the highway during braking on a downhill in the mountains in rain. Vehicle was towing just over 5000 pounds at the time, well within tow rating.

Service Antilock Brake System warning on at 19,600 miles similar to the many ABS/HCU failures reported on 2018 Ram 2500 trucks.

ABS light and traction control light comes on all the time and when lights comes on curse control stop working, by lights coming on all the times don't feel safe to drive truck.

ABS and Traction Control lights and associated chime intermittently (but relentlessly) turn on/off/on. This happened while towing a trailer in mountains and disabled my ABS, traction control and cruise control. This 2018 Ram 2500 4x4 has only 17,100 miles. The codes C2200 and C0020 that it shows, according to Ram, require an ABS module and hydraulic control unit. The latter is unavailable and even if it was, is known to fail again regularly within a couple of years. This is a HUGE safety issue we need help fixing.

The hydraulic control unit for the antilock braking system failed, causing a repeated dinging and loss of all antilock, breaking traction control, and cruise control capabilities. Dealership quotes parts are almost a year out, and I will be stuck driving the vehicle in an unsafe manner until it is repaired.

abs / traction contol light keeps coming on. dealer not able to replace part because of so many trucks having this same problem that the new ABS hydraulic control unit (HCU) will not be available until sometime in 2024 and will be up to all customers to replace at customer cost. should be a recall done becuase there is an over 50% fail rate on these units. 2017-2018 ram 2500 trucks

The Anti Lock Brake light and traction control light is on and going on and off. I am told that the HUC is in need of replacement and none are available for a $60000.00 Truck sold by Ram. This is clearly a safety issue, (Brakes) and either a Recall or a buy back of the effected vehicles need to be done. What can you do since Ram seems to be sweeping it under the rug??

Abs light, traction control and electronic braking system. Took to dealership, said its a known problem. No parts are available until February 21 2024.

ABS light and traction control light continues to be on. Disables the 4wd drive. No traction control

1. ABS/Electric Stability Control service antilock brakes lights flicker on and off. 2. When ABS light is on you could lose control of brakes due to possibility of wheels locking up. 3. Went to the dealer twice to correct the problem and still having the same issue. 4. The vehicle was inspected and worked on by Ram Dealer. 5. No warning lights before failure.

Intermittent ABS and traction control lights. Service lights come on and go off when braking or driving over bumps. Code C0020 - ABS Pump Motor Control General Electric Failure. Issue is so random I haven’t taken the truck to a service center.

Abs problems due to HCU

I have been trying to get my vehicle with 17 k miles repaired since May 2023, and to date the parts, ABS Module and HCU pump are not available. Winter is fast approaching and my ABS light continues to flash also disabling the cruise control. The constant dinging is very annoying and driving the vehicle continues to be very aggravating. I have repeatedly contacted my local dealer and they continue to push out the date when parts will be available. They are not able to confirm engineering design review due in February 2024 when parts might be available. Really! Would it be possible for NHTSA to advise me on maybe when a solution to this problem might happen.

Tractions control and abs light consistently flashing. Throwing a code for the HCU. I see there’s a class action lawsuit for this already placed.

I keep getting warning lights for ABS problems. Saw there was recalls for the 2019-2022 and saw there was a class action law suit for the 2018 models.

Abs light is on. Needs an abs pump. The pumps are not available from Chrysler. This has been an issue on my truck since November 2022.

The truck started intermittently throwing code for C0020-01 (service Antilock Brake system). I will intermittently lose ABS/Cruise/trailer brakes, and being the primary vehicle in our family, the truck has become unsafe to transport my wife and 7 months old child. I've aware the HCU/ABS module both need replaced, but some of these parts aren't available from the dealer, and it will be multiple thousand dollars to repair IF they ever get the parts in. This is a known, very dangerous, safety issue that FCA need to address.

Continued failure of hydraulic control unit (HCU) and Anti-lock brake system (ABS) module causing fluctuations in brakes at times (have to press harder on brakes) and lights go on and off, sometimes staying on for lengthy periods (usually on highway) or while driving and disables the cruise control. Second time in just under 3 years (fixed in Nov 2020 and reported to dealer Sept 2023), same issue on parts both time, fix identified as faulty HCU and ABS module as dealer identified issue and placed order for parts (5 month backorder to Feb 2024 as apparently very common issue with these trucks). The issue is both the change in brake sensitivity due to this part failure and the sudden cancellation of cruise control, the braking impacts the braking performance and cruise control drop out causing sudden drop in speed on highways.

While driving the ABS warning light, and traction control light illuminated, along with a chime. The messages "Service Anti-Lock Braking System", and "Service Electronic Braking System" showed on the dashboard screen. These warnings would come and go very frequently while driving, each time with an audible chime. At times, this would happen every 4-5 seconds, making it very difficult to concentrate on the road. Sometimes the messages would be gone for 1-2 hours but would always return. When the warnings were present, the truck would have no ABS, traction control, or cruise control available. This made towing a trailer much more dangerous. My truck was out of warranty but only had around 33,000 miles at the time. The local Ram dealer replaced the ABS module, as well as the brake hydraulic control unit. The problem has not returned. I have since learned from the online community that this is a very common problem and think it's something the NHTSA should look at. Due to the frequency of which these failures are occurring, a lot of owners aren't able to get their vehicle fixed because of the increased demand on the parts required.

My dashboard keeps flashing “Service Antilock Brake System” and “Service Electronic Braking System”. The warning or notification goes out and comes back almost every time you hit a slight bump in the road or even if you don't. Seems to be very intermittent. Cruise control goes out when the lights are on and the truck lurches a bit. The dings and lights flashing are very annoying. Took it in to my local dealer and they checked the electronic codes and found a new module is $510 and NO ETA to dealer and the HCU is $262 and not available until 2/21/24!!! Total to install will be $800+ NOT covered under any warranty. They tell me it's not dangerous to drive since I can still brake....REALLY??? No ABS brakes seems to ba a severe problem to me. There is a class action lawsuit about this in CA: The FCA Ram defect class action lawsuit is Neu, et al. v. FCA US LLC, et al., Case No. 5:23-cv-00509, in the U.S. District Court for the Central District of California.

ABS service warning and Traction control light shows intrmittently and disapears Planning to take to dealer

The truck has a faulty antilock brake hydraulic assembly. The ABS and Traction control warning lights illuminate intermittently, especially when hitting bumps in the road. When the lights are in the ABS brakes and traction control systems are not available. The trouble code in the ABS module is for an open circuit in the ABS pump motor. When the issue occurs and the lights are on the ABS brakes and traction control do not function correctly. I am a professional automotive diagnostician that owns a vehicle diagnostic business and I am also a college instructor for automotive courses. So please understand this issue was diagnosed properly. I have diagnosed the issue to an open circuit internally to the ABS pump motor which is part of the ABS hydraulic assembly. The motor was disassembled and Inspected after all of the external circuits were properly diagnosed and no issues were found with any associated external wiring or controls. It was found that the brushes in the motor assembly that contact the commutator inside the motor are sticking in the brush holders. This sticking of the brushes in the brush holder cause the brushes to lose contact with the motor rotor which then causes the code to set and the lights to illuminate. This is more apt to happen when the motor is shaken by the movement of the vehicle hitting bumps causing the commutator to move away from the brushes which are sticking in the brush holders. This in turn sets the motor circuit open code. I have diagnosed this same issue for several other repair shops in my area. All of the involved trucks are 2018 Ram 2500. They all have the same exact issue.

The ABS system has went out again. This is the second time owning this truck and back orders are 9 months out. First time wears around 30k miles. It’s a common problem with this year truck. From new to old.

Abs/traction control errors Alarm keeps coming in and going off This is the 3rd time this truck has had the same issue

2018 RAM 2500, 140,000 miles. During a long trip home to ND traveling on interstate 29 in SD warning lights appeared on the dash indication ABS problems. The cruise control also stopped working. We checked it with a code reader and it indicated a cose associated with the ABS brake system failure. ABS brake system failure, ABS pump motor control failure, also affecting loss of cruise control. Code C0020-01 confirmed. RAM dealers report that corrected replacement parts are not available and loss of brakes could result possibly causing harm to the vehicle and passengers.

Warning light stating "Service Automatic Braking System". Failed ABS module and Hydraulic Control Unit resulting in absence of Automatic Braking System brakes. Taken to Dealership and told unable to fix due to inability to find parts...Earliest part will be available is 6 months from time of inspection.

anti-lock braking system has failed for the second time. First time was 2 yrs ago while under warranty. Truck only has 47430 mi on it.

The ABS pump has failed for the second time, my vehicle has less than 80000 miles on it. The first replacement was covered under factory warranty. I have researched this issue and have found this to be a common issue and at this time the factory is not issuing a recall. Dodge/Ram is well aware of this issue and the repair should be covered as a factory defect.

ABS, TRACTION CONTROL LIGHTS ON, DEFECTIVE HYDRAULIC CONTROL UNIT. SECOND TIME IT HAS GONE BAD, WARRENTY THE FIRST TIME, NEEDS TO BE REPLACED AGAIN, NEED TO LOOK INTO A SAFETY RECALL.

ABS Failure Code 0020.1/1

2018 RAM 2500 diesel purchased brand new in October of 2018. Continuous issues with the ABS Module and hydraulic control unit starting at approximately 23,000 miles. This was unfortunately past the 3 year bumper to bumper warranty. This affects the performance of the ABS brakes, including the brakes freezing up in the closed position, along with a constant chime and notification on the dashboard. Upon doing research this appears to be an extremely common issue with the 2018 models and a recall has already been issued for the 2019 model. The OEM ABS modules have a 6-9 month wait when ordered and the repair is approximately $1,500.

Whenever it rains or is high humidity, my dashboard lights up and repeatedly chimes with ABS lights and Electronic Braking System error. The error repeats itself on and off again every few seconds. It is a dangerous distraction of error messages. Since it is raining, all traction control and ABS systems deactivate themselves with this error. I spun out this morning due to the error. It is absolutely dangerous. This is the EXACT error that occurred on my previous Ram. This is a dangerous faulty hydraulic control unit (and ABS system). Upon a little research, I found tens of thousands of posts of owners being stranded or driving without ABS / traction control due to this malfunction. This is deadly and needs to be recalled. RAM is aware of this issue but has not issued a recall. It is raining today, and my RAM will not have traction control or ABS. This is unacceptable. This is affecting tens of thousands of owners. With upwards of $1,600 for a repair. Yet, the part can create a fault AGAIN within weeks or months. DANGEROUS.

Braking failed on vehicle, manufacturer refuses to provide repairs parts nationwide on all Ram 1500,2500,3500 trucks

My 2018 RAM ABS warning indicator light goes on and off continually. Also the HTC control unit warning lights. Dealership has a back order of 12 months is not more to replace the parts. 123 ordered at our local dealership alone. Please force Dodge to recall and replace faulty parts at their expense.

ABS light and traction control light are coming on. Causing excessive dinging and cruise control not working. Also experienced flat spotting on my tires.

38k miles ABS Unit has been replaced along w hydraulic pump. Just over 2 yrs 20k miles it’s out again! This is a know problem and they will not take responsibility for it! What has to happen someone die because of the ABs failure?

The ABS and traction control warning lights recently came on causing the antilock brake system to not function. Took the truck to the dealer and was informed that the HCU for the antilock brake system is bad. I was told that the replacement part is on back order and they have not been able to locate one yet.

Service ABS lights on the dash, bad pump, brakes locked up in two different occasions. Truck is at the dealership, however, I need to pick it up due to no parts available to repair. My extended warranty is about to expire in the next 4k miles and I should not have to pay for this repair out of pocket, when I took the truck to the dealership before the warranty expires for this issue. My research revealed that this is a known problem with these trucks, which is totally unacceptable for the price we pay to purchase them. This issue started at around 34,000 miles. ***Last Dodge I will purchase****

Hydralic control unit is bad causing on dash safety alert for service electronic brake system alert and anti lock brake system alert. When towing will not have brakes to assist in stopping tow vehicle. The alarm constantly going off distract your attention from the road. Upon going to the dealer for repairs I was told they are on national back order and may not be available until after the 1st of the year. It apparently a widespread issue with all 2017 and 2018 Ram 2500s. I am unable to tow my 38' 5th wheel camper for fear I will lose my brakes on the tow vehicle putting myself and others at risk. The anti lock brakes not functioning properly could result in losing control of the vehicle when road conditions are wet or slippery. This loss of traction put me and other motorist at risk. Ram know there is a problem with the HCU. My understanding is they have had to completely re-engineer the part and as such has created an availability problem for anyone owning these vehicles. There are several blogs and forums online describing this as well as a class action suit initiated by the state of California. Would appreciate you looking into this matter and getting Ram to do the right thing. Thank You

Abs and traction control issues. Intermittent lights come on and lose cruise control. 2018 Ram 2500, with 29000 miles.

I am experiencing intermittent warning by dash red light, warning dings & digital warning. Check brake system. The issue seems to be increasing in frequency as the last time I used the vehicle-it dinged every few miles. I understand that the ABS & TSC systems are inactive when warning displays. I called my local dealer to have vehicle inspected/ repaired and was told to come in for diagnosis but the parts for suspected failure are not currently available. I am in an area with rain expected for several days and am concerned with driving under these conditions.

The ABS control pump motor is malfunctioning causing loss of the anti lock braking, four wheel drive, and cruise control. The dealerships have no ability to get parts to repair and they have been on back order indefinitely.

Anti-Lock Braking System Faulting. Near catastrophic incidents while towing.

The ABS and traction control indicator lights come on and off intermittently. This is a huge safety concern has the ABS and traction control may malfunction. This issue has been brought to the dealer and they replaced parts less than two years ago. It has reoccurred less than two years later.

IN 2020 MY ABS CLONTROL MODULE FAILED AT ABOUT 20000 MILES. I HAD IT REPLACED UNDER WARRANTY WITH NO ISSUES. IN MAY OF THIS YEAR (2023) IT STARTED FLASHING ON AND OFF WHILE DRIVING AGAIN. I TOOK IT TO THE DEALERSHIP AND THEY TOLD ME IT NEEDED REPLACING AGAIN BUT THEY DO NOT HAVE AND CANNOT GET THE PART. IT HAS GOTTEN WORSE AND WORSE. I CAN TELL IT IS AFFECTING MY BRAKES ALONG WITH I CANNOT USE MY CRUISE CONTROL. I HAVE BEEN BACK MULTIPLE TIMES TO CHECK WITH THE DEALERSHIP AND THEY TELL ME THE PART IS BACK ORDERED. LAST TIME I WAS THERE IN SEPTEMBER THEY TOLD ME IT WOULD BE FEBRUARY OF NEXT YEAR AND THAT IT IS NOT COVERED UNDER POWER TRAIN WARRANTY SO I WILL HAVE TO PAY OUT OF POCKET FOR SOMETHING THEY HAVE ALREADY REPLACED ONCE FOR SAME ISSUE.. THE BRAKE LIGHT, TRACTION CONTROL LAMP, AND ABS LAMP ALL FLASH ON AND OFF CONSTANTLY WHILE DRIVING

ABS system needs maintenance, no fix up to this.point dealer does not want to assist.

Abs traction control light has been going on and off since truck has had 15000 miles dealer replaced abs pump still has issues light is intermittent when it comes on cruise control shuts off truck now has 53921 miles on it and the dealership doesn’t know why light goes on and off

Service ABS and Electrical Braking System lights constantly turn on and off making an audible beeping noise while vehicle is driving. Sometimes lights stay off for a little, other times it turns on and off repeatedly, and sometimes it stays on for entire time. Unknown if braking system is working properly if they were needed in an emergency situation.

2018 Ram Sept 23, 2020 at 15,000 miles ABS light flashed on. Code said pump electrical failure. Dealer replace under warranty. Oct 12, 2023 at 50,900 miles, service ABS notice flashes on screen. Dealer confirmed ABS failure but said parts were on indefinite back order. Said last one took over a year to get parts in.

Intermittent warnings of ABS system needing maintenance while driving. No known cause or correlation to type of road/weather conditions. Intermittent ABS failure affects ability to use cruise control. This started when the truck was at 52k miles. This has been happening for over a year now and we have been told that there is an indefinite timeframe for repair due to massive back orders.

Bought the truck new in 2018 from Planet Dodgein Miami. One year later (2019)the service braking system light came on. Dealer fixed the issue under the warranty. One and a half years later (2021, same issue and the dealer fixed the issue under the warranty at Napleton Dodge in Clermont Florida. 1.5 years later (2022), same issue. Dealer (Advantage Dodge Mount Dora Florida. said they needed to replace the same parts and added they needed to replace an additional part to correct the issue. This time I was charged $1000. Another year later (10/2023) the same issue and I'm being told by Advantage Dodge in Mount Dora Florida, the warranty will not cover and I have to pay $1500. Dealer told me it should be covered under the original warranty. Gave me the number to warranty (800)992-1997 (Trevor) told me not covered any longer and the dealer should warranty. Called the dealer back and they told me to call the number back. I did and was told a second time and they told me it is no longer under warranty and they (Eta) told me to call a second number (800)521-9922. Called that number and they have me a third number to call (800)765-7732. They told me the dealer should handle the issue and it's not covered under original warranty. Now the dealer will not return my call and they still have my truck.

ABS warning light intermittent chime and warning. It affects cruise control and highway/street handling. Warning light and chime stays on or is intermittent.

Almost constant beeping and flashing indicators telling me to "Service Anti-Lock Brake" system. Taken to repair shop and they tell me there is not a fix and there is an engineering stop on the HCU. A code read returns an active C0020-01 code. The brakes do seem to work but the ABS and Traction Control indicators flash constantly with the beeping. I haven't test the ABS functionality but would assume it is not functional based on the indicators.

Vehicle randomly throws error codes on the dashboard. 1. Service Antilock Braking System 2. Service ABS Braking System. When this occurs, an audible chime sounds, and a visual warning warning displays on the digital dashboard covering current speed and other information. Also the cruise control is turned off, and I believe all ABS and Traction control features are disabled. While I have not yet experienced a related accident, I have had several close calls with other vehicles following behind me. By the time I react, they are on or near my tail end and nearly rear ended me. I contacted my local Dodge Ram dealership and they told me that the needed part (hydraulic control unit) has been backordered for nearly 4 years. They cannot disable the warning light nor the audible chime which may sound and flash 15-20 times a minute sometimes. They suggested I contact Mopar customer service, which I did and they ended up transferring me to another dealership that said I had to pay 300 dollars for a diagnostic and it would 2-4 days. If they cannot find the replacement part, I am out of luck on the diagnostic fee. No parts are available.

My ABS HCU sensor has failed and is causing my ABS system, traction control, and cruise control to stop working. Due to the high failure rate of this part RAM / Mopar is refusing to release any available parts for repair until February / March 2024. There are currently 4,000 of these parts in stock on the east coast but the company will not release them until 2024. Instead RAM / Mopar is asking me to continue driving my vehicle for 5 months with a failing ABS system, no traction control, and intermittent 4WD. The component has been inspected by the local RAM dealership and has been determined to be faulty while under warranty.

One month after the 3 year warranty ran out the truck issued a "Service ABS System" alert on the instrument panel. Had to replace the ABS Hydraulic Module at the dealer. 2 Years and 2 months, just after the additional warranty ran out, the same part failed again. Same warning on the instrument panel. Again took it to Ram Service at dealer and had it replaced again. This is a faulty part and the replacements are faulty as well. It is happening so often that it is hard for the dealer to find the part.

The ABS Motor circuit on my truck is losing power. The issue is this is part of the Hydraulic Control Unit assembly and it is not serviceable without replacing the HCU. Ram does not currently have a solution to this problem. This issue shuts down my Anti-Lock Braking System, traction control and I lose trailer brakes when this system fails. This is a safety issue and a recall needs to be issued for this.

In October of 2021, my truck indicated an issue with the ABS System and the EBS System. Those two alarms would frequently go off randomly while driving, and also the cruise control would not operate during this state of alarm. It was fixed immediately by a RAM dealership; they replaced the HCU module (hydraulic control unit): part #68143491AA. Almost two years later, in September of 2023, the exact same thing happened and I took it back to the very same dealer; they confirmed the same issue and it would need a replacement HCU again, however I was informed those parts were all removed from inventory as they are being redesigned (fixed) to prevent more issues in the future, as this is a "known" problem. I am awaiting a call from them when the new "fixed" part will be available (it could be months). In the meantime I am driving the vehicle knowing that the ABS braking can go out at any time, thus driving more carefully than normal. It is also worth noting that about one month after the second occurrence of this problem, while driving with a faulty HCU, my brake line on the front driver side wheel (just about one foot from the HCU module) burst while driving and I lost almost all braking in a matter of 5 minutes. That brake line was repaired at my expense. It seems to me that could be related to the HCU issue possibly causing higher than normal pressures in the line. In my opinion, this situation is dangerous and should be raised to the level of a RECALL on that HCU part. Also, RAM should be paying for any such brake issue repairs that their truck owners have had to pay for while operating with this defective part.

The ABS light comes on intermittently with a message to have braking system serviced. This causes a loss of braking performance, & cruise control. With this happening intermittently, it is impossible to have repaired by dealership. As the error disappears. I had also had this issue with a 2017 RAM 2500 I owned previously.

Hydraulic Control Unit Failed. Yes, it is available for inspection. The hydraulic control module controls the wheel speed and traction control system, without these systems working properly it has caused traction control issues and caused loss of control of the vehicle. Yes, Patriot Dodge and Chrysler in Oakland Md Diagnosed the problem. No, the component has not been inspected! Yes, there were Two lights on the dash (ABS light and Traction control light), Also My Cruse Control would not set the speed. I lost control of my vehicle and fortunately there was no property damage, and no one was injured. If the ABS and Traction control system had been working properly this incident would not have happened. This is definitely a safety issue for these vehicle owner's and the motoring public as well as anyone in the immediate area.

Service Anti lock Braking System light came on. Took it to the dealer and was told I need a new Hydrolic Control Unit, but dealer can not even order one until February 2024 at the earliest. I now how an unsaved truck I am just stuck with

The service anti lock break system and the service electrical break system warnings keep flashing. The traction control light and the ABS light continuously flash as well.

ABS service light coming on, and service electronic brake system keeps coming on. Recall on 2019-2022 RAMS for same issue. Told to report issue here.

Intermittent ABS service warnings, This is a well know problem.

My 2018 Ram ABS and Traction Control light keep coming on then they go away for a few miles then come back. this item has been fixed but it came back. i spoke with the mechanic but he said, Rams have had this trouble. i'll have to keep dealing with it till they come out with a solution. i looked up the problem and seen numerous complaints same problem. i can disconnect the fuse and not have the warning bell but hen no ABS brakes. has there been a recall? (previous owner had it repaired twice but it keeps doing it.)

My Anti Lock Brakes, Traction control and power steering have gone out repeatedly on this vehicle. The ABS pump HCU unit has failed at 8,433 miles. The same thing failed again at 12,924 miles. As of this complaint the same thing has failed again at 20,000 miles. I have not had it repaired because Ram will not guarantee the new part they put in is not defective, like the original part and the 2 other replacement ABS pump they installed which have failed. I don't drive my this truck that much because without the abs for which the break system on the truck was designed for I feel like it is a danger to myself and others.

My abs brake light goes on and off cruise control just stops in the middle of the highway. I was almost hit by an eight wheeler while commuting because of it. I loose traction driving on wet roads. I have taken it to the dealership more than twice to fix the problem. So solution in sight.

Complaint already filed. Have been waiting on HCU module and ABS module for over 1 year. Intermittent braking issue, and trouble code is constantly going off. Called dealer every 3 months and no part available. They say it is an engineering hold by Ram. Latest update is to check back 2/2024.

The ABS system is not working. The warning lights for ABD and skid prevention are lit. During hard breaking the tires will lock up and slide. This also turns off the cruise control.

On or about September 2023 this vehicle, with 94k miles, has had its 2nd ABS/HBU failure. This causing the ABS and traction control lights to flash on and off with audible alarm then continuous illumination. We as a consumer buy these heavy duty vehicles to use for pulling trailers and heavy loads, It is no longer safe to do this when there is an imminent threat of brake failure. This can cause the consumer to be out financially in many ways. This component was previously inspected and replaced in 2020, with roughly 20k miles, by the dealer I purchased the truck from. Currently I have been unsuccessful locating and OEM replacement part causing the vehicle to be parked. This is a well known and documented issue on 17-18 Ram 2500-3500 heavy duty trucks that the consumer would like remedied for the safety of themselves, their families and others on the road around them.

I have had an ongoing issue with the ABS & ESP warning and warning light coming on and off. I took it into the dealership and they told me I needed to replace the ABC controller & hydraulic control unit. I don't understand why this isn't a recall or covered by RAM. I am afraid the brakes are going to fail putting my life and others in peril. I was told the repair would cost me $1200 so I have had to park the vehicle.

The ABS and traction control systems on our 2018 2500 RAM truck are failing randomly, and the warning lights are coming on. The cruise control system is also randomly failing. Therefore, as we drive the vehicle and using cruise control the vehicle will randomly turn off the system causing safety concerns. The braking system and traction safety systems are not working properly and safely. The cruise control issues have been occurring for about 2 to 3 months. Over the last 1 to 1.5 months the ABS and traction control systems have started randomly failing and turning on the warnings lights and bell. We took the vehicle in for service today at the RAM dealer and was informed that the parts are backordered and unknown when any parts would be available. The dealer confirmed the systems are not functioning properly and provided written estimates and summaries of their findings. The dealer advises to replace the HCU and retest the system. The dealer advised to replace the steering wheel wiring and cruise control switch. The vehicle mileage at the time of the dealer evaluations was 23,052 miles.

This is now my second ABS module that has failed. I gave a detailed description of the brushes getting stuck in the valve body motor. This particular situation is exactly the same as before. Intermittent on/off of the traction control ABS and stability system. I have not disassembled this particular unit because of the part being unavailable. Tapping on the motor itself will make the fault go away which leads me to believe that it's similar same failure. The tapping motion allows the brush to move forward and touch the commutator. I still have the original motor from my initial failure analysis. If it would be of any use, you're more than welcome to reach out and I will be glad to ship it to you. This is a serious safety problem because you never know if the system is working or not.

Anti Lock brake system and service electronic brake system message keeps going on & off every 30 seconds & will shut down cruise control if it is engaged. Happened in 10/11/2021 & now 10/8/ 2023.

Hydraulic Control Unit (HCU) has failed, causing repeated ABS and traction control warning lights with audible chimes. Vehicle is currently at the dealer to try and fix the issue. This first occurred during a long road trip with no prior issues or signs of a problem. The first time it occurred, I was towing a trailer and on cruise control. When the dash lights and audible chime went off, it kicked me out of cruise control, which immediately caused the vehicle to slow while in traffic at highway speeds. While researching this issue recently, it seems this is a common and well known issue with Ram trucks of similar year and model, with no recalls being issued.

Multiple service ABS warning lights every time it is driven. ABS will not work sometimes, dealer replaced ABS HCU and continue to have same issues. This is very common in 2017 and 2018 Ram diesel vehicles.

ABS and stability control failure. First intermittent then continuous. Dealership said the problem is the HCU solely from my description. Known problem. They also said replacement parts not available to order until at least February 2024. I believe a recall is warranted.

The Antilock Braking System is faulty. The Service Braking System is faulty. I was trailering under load when I had to apply breaks due to a road hazard. My Antilock Braking system did not function properly and my tires locked up. My vehicle was in a slide while trailering a load. Fortunately I was able to maintain control and avoid an accident. I had previously contacted my dealer about the warning light constantly alerting me that I needed to service the Antilock Braking System and the Service Brake System. I was told by the Service Department and Steele Chrysler Jeep Dodge Ram in Gonzales, TX that they were aware of the issues with the HCU on 2017-2018 Ram 2500/3500. They stated that there were no replacement parts available and that I should continue driving my vehicle with the Warnings constantly going off on my dash. I am not happy about this situation and feel a resolution needs to be formulated by the manufacturer. I am aware now of many complaints regarding this part issue with this make and model. I rely on my vehicle for my livelihood. I cannot drive my vehicle as it was designed to be driven as per the manufacturer's design.

ABS CONTROL MODULE light stays on and dealer says the module is defected and has to be replaced at a cost of around $2600.00. No parts are available due to UAW strike. Told to drive it as is cause parts may not be available till January. I feel Ram corporation should be responsible for cost to repair vehicle only has 46000 miles. Thank you

This is the second complaint filed for the same issue. Tracking number 11441949. I understand there is an investigation open for this issue. PE 22-012. Opened 11/28/22. My truck was repaired under warranty December of 2021 It has failed again in September of 2023. after less than 2 years and 20,000 miles. The ABS/Traction control system as well as cruise control unexpectedly without warning stops working. Since I use my truck to tow heavy trailers this is not a very good scenario. The alarm and warning on the dash at times repeatedly and randomly sounds while driving. When this occurs I have no ABS function, or hill decent control. The Hydraulic Control Unit Part #68143491aa is the part that failed and was replaced under warranty. It has since been obsoleted by Ram and replaced by a different part #. Was this because they knew they had a problem? At any rate, I am left to pay to have this fixed again and worry about when it might fail the next time.

Check engine lights came on flashing “service abs” and “ break system malfunction “. Took to dealer and had to have HCU ( hydraulic control unit) for ABS system replaced.. it was a dangerous situation as the trailer brakes were rendered useless, as was the cruise control. The breaks still worked but not the ABS part, so could possibly lock up and loose control during an emergency event.

I have a 2018 Ram 2500 which has been throwing an error code for the last year to service the electronic braking system. The dealer says it is the HCU and it is a known problem and that the manufacturer will not have a fix till mid 2024. Meanwhile my truck is not drivable as it is a significant safety hazard. The dealer says it is now out of warranty and I will be responsible for replacement costs when the manufacturer finds a solution. I live in Michigan and I now can’t drive my truck as it is a safety hazard and I can’t sell it cause nobody will buy it with this issue. The constant flashing of the “Service Electronic Braking System” code and constant dinging when the light comes on also makes the truck undrivable. Meanwhile I’m stuck with no truck.

My truck has the same issue as many thousands of other RAM owners. The forums are full of people with the same issue. It clearly is a faulty part/design or similar. My "check ABS/ Traction Control- Brake light" turns on and off intermediately all the time. It is an issue many have had and had fixed for between $800-1,000.00. For your reference here are some links to forums showing this issue in fact a OEM problem. Apparently there are class action law suits going on in Texas and California over this matter. [XXX] [XXX] [XXX] There are many more. RAM should have to furnish a recall and fix this issue at no cost. Parts are not available until February of 2024. This is a safety concern!! This issue will not allow the use of cruise control or remote start. Winter is coming and im not sure the ABS works as long as the light is on. RAM needs to supply parts faster than Feb 2024 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

the abs module and the hydraulic pump have a issue that turns on the abs and light and turns off the cruise control and reverts to non abs braking due to faulty module and pump assembly that was changed already and now the wont cover this under any warrenty known faulty part

ABS/TRACTION CONTROL light comes on intermittently while driving and or braking, when this happens the cruise control quits working. Took to the dealership they diagnosed this to have a code C0020. The failure is the Hydraulic Control Unit. Which is on back order with no ETA. When the light comes on you have no ABS or traction control. The dealership inspected the fuses, wiring.This problem happens every time you drive it and can be duplicated.

The ABS/Traction Control module has a known by manufacturer malfunction where the system fails, and you can be left without proper abs and traction control. This system can malfunction causing something as simply as the inability to activate cruise control to the inability to have proper abs braking. I've taken the truck to an independent shop as well as the delarship and both times they say there is a backorder on the part that can take over a year to replace and the charge for a safety feature that is a known malfunction is over $500. Also to lead on with the frustration of this, they offer just to use your standard brakes without braking hard (as if one can control unknown incidents requiring harder braking) as well as using the exhaust brake system. This is a safety concern that needs to be addressed and fixed, and not told to wait over a years time to possibly get the control module.

Intermittent ABS light and Service Electronic Braking System lights coming on and off. Appears from previous reports this is a known issue that has been going on for years now with this vehicle and should be fixed. I purchased a new hydraulic and electronic module from dealer at around 35000 miles and replaced. Issue was fixed or so I thought, at around 70000 miles lights are intermittently on and off again. No known issue was contacting ram direct, dealer I bought vehicle from stated the electronic module is backordered and has already been replaced with another part number, I believe it was a faulty replacement from the get go. Hydraulic module was said to be under engineered testing again per the dealer. Extremely frustrating from the customer end, no cruise, no abs braking capabilities. No known deaths to this point linked to this specific issue to my knowledge but I wonder if Ram will move a little faster on the fix or recall once they have something fatal on their backs for this.

Brakes don't seem to stop as they should and now the lights came on and dealership says I need a new abs pump and there are none available

When driving down the road the anti-lock brake and traction control lights came on. Anti-lock brakes quit working making the vehicle unsafe to drive. C0020-01 trouble code was noted. HBU and or ABS module fault is apparent.

ABS and Traction control light come on intermittently causing cruise control to kick out and not work. Also causes an alarm to ding over and over. This is a known problem with the Ram HD for this year.

The ABS Control module has been replaced once for constantly giving the “service anti-lock braking system” message and making a dinging sound. The repair worked for a little over a year and it’s happening again.

ABS pump fault C0020-01

Abs module. Antilock brake system failure. Known issue by manufacturer.

Antilock braking systems does not work

I’ve just started experiencing the ABS light coming off and on. Did some research and find that this is a common problem wish my truck. Making appointment with dealer to have it checked out. Also about a year ago my radio had to be replaced as the screen was delaminating. Was told this also common problem but Ram was of no help. Had to buy new radio. Now my truck only has 32,000 miles on it and was under 30 when radio was replaced. But I’m second owner and ram would not warranty it. Now that I’m researching this site I’m seeing many problems that are consistent with mine. This should be a recall. The brakes and the radios. Think I’ll be trading this truck off.

ABS/Trac lights ding constantly with the dash displaying "service electronic stability" or something along those lines. ABS system becomes inoperable as well as kicking your cruise control off. Very unsafe and parts are not available for repair as well as Ram not taking recall action up to this point.

Abs traction control light is on again this is the second time this has happened dealer replaced abs module lasted a little over two years now problem has started again.

ABS constantly fails. Check ABS and traction control fail light constantly appearing. Suspected ABS module failure.

2018 Ram 2500. Trouble code for service electronic brake system, traction control deactivation, cruise control deactivation, ABS deactivation occurs at all speeds and all surfaces intermittently and the trouble code will activate and deactivate for up to approximately 45 minutes continuously . Ram certified dealership service departments in 2 states have declared it a known issue, have stated there is a TSB for repair but parts are unavailable with no ETA. Vehicle is under warranty but no remedy except to wait for parts which I have done for almost 1 year. Several other colleagues have the same issue which makes me concerned that probably 1 in every 3 2018 Ram 2500s are or will become safety concerns. It would be my intention to sell this unsafe vehicle as it is a primary means of transportation for my school aged children but no dealership will entertain a trade or severally reduces the trade in amount due to an issue that I can’t even through a factory warranty still being active have resolved. I have no other recourse at this time other than to advocate for individuals to sign up for the class action lawsuit against FCA which covers this exact issue which will hopefully force FCA to fix these unsafe vehicles before deaths or serious injury occur. Any help your organization could be would be appreciated as this is a glaring safety issue known by the manufacturer and these vehicles are used for towing.

Defective Brake Control Module and Hydraulic Control Unit intermittently cause ABS and Traction Control warning lights and error messages to repair ABS and Electronic Brake System. This causes cruise control to drop and no ABS braking. This first happened 2 years ago and was dealer repaired and now it's happening again. This is obviously caused due to defective parts.

ABS / TRACTION CONTROL LIGHT ON IN THE DASH. CRUISE CONTROL INOP. THIS IS A KNOWN ISSUE, IN FACT 2019-2022 TRUCK HAD A RECALL ISSUED. RAM NEEDS TO ADDRESS THIS SAFETY ISSUE

abs system fail off and on which disengages the cruise control.

ABS module failure, brakes can potentially lock up causing you to slide. Preoblem has been verified , but has not need inspected by manufacturer (on my vehicle). And there were no symptoms, light came on as soon as it failed

I have the warning light that comes on and message stating to " Service Antilock Brake System" and " Service Electronic Braking System". I have spoken to 2 different dealerships, and both tell me that it is an issue with the ABS Hydraulic Control Unit. Both dealerships tell me that no replacement parts can be ordered and there is nothing that can be done to fix problem. The vehicle has less than 50,000 miles and the brakes do not work as they should. This is a major safety issue, and I am being told there is nothing that can be done about it.

I keep getting alarms on my truck for the ABS system and brake controlling system. I took the vehicle to a dealer to find out the problem and was told the HCU and the ABS module both need to be replaced and this is a common issue with my year and model truck. I was informed my repair bill would be over $1900. I tow a fifth wheel camper on a regular basis and do not want to have my brakes lock up while an 11,000 pound trailer is behind me.

I have had problems with the ABS lights and warning come on 4 times. 2 times I have had it repaired by Philips Dodge Ram in Ocala Florida. I had it repaired at my own expense at Hilton Automotive and once under warranty at Hilton Automotive. My truck only has 12145 miles on it. The lights are still on and the warning flashes at times. It appears to have something to do with the temperature. After repairing it worked for a week or so until the temperature dropped under 75 at night. I cannot afford to spend over $1000 a month to keep this straight.

Electronic Braking System and Anti-Lock Braking System has intermittent failure and any speed. The safety of those in the vehicle are at risk by unsafe braking and unpredictable braking. Warning signals turn on and off while driving. Started to appear around 44,000 miles.

The ABS and Traction Control lights constantly come on, even after replacement HCU and ABS parts are replaced. It’s a once a year fix, and should be recalled. Once the lights come on, braking is affected, and cruise control no longer functions. I used a previous date, because I need to replace the parts again, for the third time. I have asked Ram support to just send me the parts, and I will do the repair, but unfortunately, they prefer that I continue to pay the dealer to repeat the same repair over and over.

My ABS and traction control light intermittently blinks on and off. I took my vehicle to the dealership and was told this is a known issue. That I need a new ABS power module and controller. The parts are very expensive and on back order. I was informed to continue driving the vehicle until the parts are available.

In July, I drove over a bridge expander bump and now I am getting two errors: 1) Service anti-lock braking system with the ABS light on; 2) Service electronic brake system with the traction control light lit. The lights and notice come on then go off for a few minutes then back on again. This repeats until I turn the truck off and restart it. It then stopped for several months, but is now doing it again yesterday after driving over a very small bump in the road. My vehicle is available for inspection upon request. This problem puts me and my family at risk because the anti-lock braking system and traction control are deactivated during these incidents. I am not able to reproduce the problem at will, it happens randomly and intermittently. The vehicle has not been inspected yet. On-line research indicates many owners are having to replace ABS sensor and pump around the same amount of mileage as mine.

The truck consistently flashes a warning for “Service Antilock Brake System” and a scanning tool provides the code C0020-01. The truck was evaluated at a local mechanic, who indicated the code represented a general ABS system failure. I have researched the issue and found that this problem is a common complaint with 2018 Ram 2500s.

Starting March of 2022 I began having intermittent alarms for the anti-lock brake system needing to be serviced. Often the alarm would come on and off going over small bumps in the road. With time the issue became worse and the alarm is on all the time. This affects the vehicles anti-lock brakes, electronic stability control, and the cruise control. I took my car to a mechanic and they found that both the hydraulic control unit and the anti-lock brake system module need to be replaced. Cost is over $2000, but feel I need to replace to have a safe vehicle as I often pull a trailer.

The ABS system is not working it has a C0020-01 code. Yes it is available for inspection 24 hour a day. The anti-lock system did not activate in slick rainy conditions. The problem has been confirmed by an independent service center. Messages- Service Electric braking system. Warning Lamps- ABS and traction control. Other symptoms- loss on cruise control. All of these symptoms started in July of 2023 with 80k miles on vehicle.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the brake pedal was depressed but the vehicle was slow to respond or stop. The ABS and traction control warning lights were illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the hydraulic control unit needed to be replaced. The vehicle was repaired under the warranty, but the failure recurred. The service electronic stabili-trak message was displayed. The vehicle was taken to an independent mechanic; there was a hard code retrieved: COO2O-O1; related to the ABS pump motor control. The manufacturer was not contacted. The failure mileage was approximately 21,477.

Mileage: 21,477

The abs and traction control light are flashing on and off SEVERAL times especially when on a rough road. It kicks my cruise off and sometimes stays on which locks the diff and disengages any ABS functions resulting in the loss of braking performance and capability.

C0020-01 ABS Pump Motor Control Electrical Failure.

My ABS and traction control lights keep coming on intermittently with a message saying service electronic brake system and anti-lock braking system.

ABS light coming on and going off like all ram 2018

ABS code c0020-01 indication of module failure. This is the second module on the truck. Seems to be a major issue with these year trucks and back ordered parts for there past several.

Antilock brake light and traction control failed. Bad HCU

The contact owns a 2018 Ram 2500. The contact stated while driving at approximately 40 MPH, the ABS warning light illuminated with an audible chime. The contact stated that the failure had been intermittent but had become a recurring failure while driving at various speeds. The contact stated that when the ABS warning light illuminated with the cruise control engaged, the vehicle would revert to manual mode and turn off the cruise control. Additionally, the cruise control could not be re-engaged. The contact also stated that when the ABS warning light was illuminated, the brake pedal would feel soft or "mushy" while depressed. Additionally, the contact stated that while making a tight turn to either to the right or left, the steering wheel felt loose. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the ABS Control Module needed to be replaced. The steering wheel failure had not been diagnosed. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 110,000. The VIN was not available.

Mileage: 110,000

Light on dash came on ,brake pedal got so hard to push,almost could not stop.Had to leave truck parked for 2 months waiting for parts.Was told by Mopar parts the anti lock solenoid and control unit were a problem,and would probably fail again

At approximately 30,000 miles the vehicle warning lights for "Service ABS" and "Service Electronic Brake System" began flashing intermittently. I took it to the local dealer and they replaced the Hydraulic Control Unit (HCU) on 5/12/2021. Approximately 2 months ago the exact same warning lights began flashing again so we took it back to the dealer yesterday 9/28/2023, 53,000 miles, and they diagnosed it as being the HCU and recommended that we do not drive the vehicle. They want to charge me for the exact same repairs that happened 23,000 miles ago. This issue is known but yet they will not fix this vital safety component of the vehicle. I cannot believe that a recall has not been initiated for this safety hazard.

ABS/HCU modules have failed. A loss of ABS and braking power have been experienced. When towing, this creates a problem as it happens very suddenly and intermittently, placing myself and others at risk of loss of braking power. Warning lamps indicating ABS failure/electronic braking system service is needed come on only when braking, and is intermittent. There is no indication of a problem until brakes are applied.

I have approximately 86000 miles on my truck and today the Service Electronic Brake system warning starting coming on and off. Along with the ABS light and traction control light. Randomly flashing on and then off. Staying off most of the time. I did a search and apparently this is a huge issue with these trucks, a couple of electronic assemblies melting together and going out. This needs to be a recall that Ram pays for. What happens if my brakes go out?

ABS and Traction Control code warning lights appear intermittently on instrument panel stating “service electronic braking system” and “service ABS system.” These indicators flash consistently on the IP but do not stay constant currently. Failure of these systems could result in loss of control of the vehicle during emergency breaking by allowing the tires to lock up during breaking. Code has been verified by Champion Chrysler Jeep in Brighton Michigan as “ABS Pump Motor Control.”

Antilock Brake System and Traction Control intermittent warnings while driving. Affects ability to use cruise control and Tow / Haul capability. If in tow/haul mod ABS warning flashes will also get Check Engine Light warning.

Keep getting “service anti-locking brake system” and “service electronic brake system” that intermittently turns off and on. 2018 Ram 2500 6.4L with 81,000 miles. Appears to be a common issue but no recall has been made.

Recently the ABS Warning light and Service Electronic Braking System light have been coming on intermittently. When it happens an audible alarm goes off and several functions shut down, like the cruise control. The problem has no rhyme or reason and some days it happens for several hours and some days it never happens. I am concerned that the ABS is not working properly but also concerned that I might be using cruise control on the highway and it shuts down creating a hazard and possibly accident. I have not contacted the dealer but see that it is a common problem with my vehicle on online forums and that there are class action suits for the issue. This should be handled by the manufacturer with a recall before someone gets killed. Currently the dealers are making a fortune making repairs that often recur in a short period.

While driving ABS and traction control lights came on and cruise control would no longer function. This has occurred 3 times and had to be repaired 3 times. 10/10/2019, 07/20/2021,and 08/19/2023. The parts replaced: 68347098-AB Module AN 08035030, 68143491-AA Control A 08035030, 68143491-AA Control Anti-LO 080, 68143491-AB Control Anti-LO 080. The parts are not available for inspection. Also, brake fluid 4318080-AD was replaced or added each time. These parts were replaced by authorized Dodge Ram dealers, one in Michigan and twice by a local Dodge Ram dealer in Florida. No warning of problem and vehicle still functioned except for cruise control. Problem first occurred at 3,305 miles, then at 17,161 miles, then at 25,203 miles

I have a 2018 Dodge Ram 2500 pickup truck and my ABS engine light came on back in February 2023 indicating that I have a problem with my braking and traction control system. It was because of the Hydraulic Control Module was bad. I Contacted a Factory Chrysler Parts supplier to obtain a new part to have it replaced but they were on backorder until June. In June I contacted them again and was told they were on back order until October 2023. I just contacted them again 9/27/23 and now I am being told the part is on back order until February 2024. This will be a full year causing me to drive without the ABS or Traction control not working, as well as not having cruise control. Doing a search on the internet there are a lot of others having the same issue which is bad enough but when you can't even get the replacement part for over a year on a piece of safety equipment for your vehicle . This is more then a safety issue.

Failure of the HCU (Hydraulic Control Unit) and ABS module. Caused loss of ABS system, Electronics Stability Control system, Electronic braking system, cruise control. Messages appeared on dash. All associated warning lights illuminated. Dealer stated this is a known problem and parts have been on backorder.

I bought this truck new from the dealer. At 18,920 miles, the ABS service light came on and the dealer said the ABS module would need to be replaced. A new part was installed. At 49,715 miles the light came on again and the dealer says the module is defective and needs to be replaced again. This part is on back order for over 2 months telling me these items are in high demand. I don't believe that items like this should be defective and require replacement in this short interval.

ABS HCU/and pump failure. Truck dies. no Brakes

My 2018 Ram 2500 has an intermittent ABS/ Service Electronic Braking System light. If I am using the cruise control when this light, comes on the cruise control turns off and the vehicle slows in front of moving traffic. I seem to also loose traction control which is dangerous when towing heavy loads.

The "service electrical brake system" and "service abs system" lights / warnings have been intermittently going on and off. This also does not allow the cruise control to work. The alerts can range from once every couple of days to repeatedly going off non-stop during my drive. Issue started around Oct of 2022. Warnings will stop for several months then return.

Service ABS system/ Electronic break system warning light came the dash control. When that happened in September of 2020 I lost traction control and cruise control on my truck. Since this accrued I’ve had several near misses of accidents do to lose of ABS system. I have not had it looked at by the dealership due to the fact that two family members have the same truck with the exact problems. They took their trucks into dealer. The 2021 was fixed under warranty and the 2017 truck was repaired out of pocket to dealership.

The “Service Anti-Lock Braking System” warning turn on and off intermittently and the yellow “ABS” and “traction control off” icon turn on and off intermittently about every 4-5 seconds. In the morning after first start, the warning lights and message proceed after the first brake pedal application. I have 78,500 miles on the truck.

I am receiving an alert in my truck that states, "Service Antilock Brake System." The emergency warning sound and lights on the dash/display appear constantly. This also affects the "Speed Control" as it kicks off the cruise control when the emergency warning sound and lights come on the dash. I have taken the vehicle to a RAM Dealership who diagnosed the issue, but was advised that parts are on backorder, which is unacceptable as this can be a very dangerous and potentially costly situation. I believe that NHTSA should look into this and provide a recall on the vehicle and expedite the process to getting, not only my vehicle, but others around the country fixed in a timely manner.

ABS Pump Motor Control - General Electrical Failure, code C0020-01, needs to be replaced. A critical item. Part is not available. I live full time in my 5th Wheel 40’ RV. Part may be under some engineering review due to failures. I need new part asap. No dealer has them. Truck is grounded.

Antilock braking system and electronic brake system warning lights flash on and off frequently while driving.

ABS Module failure and Hydraulic Pump failure.

ABS, and traction control systems fail intermittently. Lights come on and flash and ABS and cruise control no longer work. Happens at various speeds and times. Sometimes can be addressed by pulling over turning off the vehicle and restarting. Dealer states that ABS module and pump need to be replaced but have no available parts. I was advised that the estimated cost is ~ $1800 and the problem may arise again. This is on a vehicle that has less than35k miles

My truck has 32000 miles on it. Its just out of warranty and the ABS Hydraulic Control Unit is out again. This will be the third HCU put into my truck. This is a known problem from Ram and it has never been addressed. NHTSA please have RAM make it right and fix the problem so costumers are not spending 1500.00 every 15,000 miles.

The ABS/Traction Control System (TCS) error flashes intermittently while driving the vehicle. This dash warning states the ABS and TCS systems are non-functional. The vehicle is available for inspection. Safety is adversely impacted by the braking system not performing its design function. Traction Control perturbations can also have adverse impacts to the drivers control of the vehicle. This vehicle has has yet to be inspected, but similar failures for this make/model indicate a faulty ABS module and/or sensor issue. Warning error messages are broadcast frequently via the instrument cluster display. Initial warnings @ 32k miles, fall of 2023.

Service electronic brake system keeps coming up on the dash. When this happens you lose cruise control, ABS, and your abs and traction light come on. This goes on and off constantly and dings every time it happens. This is a huge problem that Chrysler is aware of but will not do anything about. I had mine replaced once and 23 months later I have the same 13000 dollar issue.

ABS goes on and off continuously. Warning messages and beeps constantly. Started October of 2022. Independent service center has been trying to get a replacement nodule from the manufacture for all most a year.

The ABS/Traction Control light continually goes on and off. I took the vehicle into Tate Dodge Ram Service center in Glen Burnie, MD the first week of January 2023. They diagnosed the problem as the ABS Control Module and Hydraulic Control Units as bad. I was told that it would take 2 weeks to get the parts. I checked back with them 2 weeks later and the ETA had changed to March 16, 2023. I left the vehicle with them and checked back after March 16th, the ETA had then been changed to August 15, 2023. I picked the vehicle up from the service department and check on it August 15th. They had received on of the part, but the other one was scheduled to be delivered Sept 15, 2023. I contacted them again on Sept 18th, when I was told that the part would not be delivered until February 15, 2024 (13+ months). The lights continue to go on and off with a bell each time the light comes on, which is very distracting. It is unsettling to drive, not knowing if my brakes will work in an emergency or if the traction control will work when we get slippery road this winter.

Service ABS and Traction control warning lights on. Computer says ABS circulation pump is bad. Part is unavailable. There should be a recall, this is a known and documented safety issue. Part is discontinued, how is it possible to disregard this issue? What are we supposed to do........drive a vehicle that wont stop as it should?

The hydraulic control unit (HCU) of the anti-lock braking system (ABS) is defective (part number 68143491AA). Without warning the defective HCU will cause the ABS and or cruise control to shut off. If this happens during hard braking, on slippery terrain or in heavy traffic, it could cause an accident. The indications the system is having a problem are warning messages on the dash display, which is great, but the warnings goes on and off for no apparent reason (does not stay on). This can happen at any speed. I replaced my HCU with the same part number (68143491AA) approximately one year ago. This corrected the problem until a couple of weeks ago when the same indicators started again. After a lot of research (Google, Ram heavy duty and Power Wagon forums) I came across one post that discussed how a brush in the motor for the HCU can become stuck, failing to maintain electrical contact with the motor windings. With nothing to lose, I decided to pull the motor off my HCU and take it apart. Once apart, I did determine that one of the brushes was in fact stuck. I am not sure if the brush became stuck just because of dirt or if the metal body the brush slides in was crimped too tight (could be a combination of both). I was able to free up the brush and put the motor back together; the motor functioned properly when bench tested. Unfortunately, I have not been able to reinsert the motor back into the HCU body (plungers are in the way and need to be compressed). I do not know if this requires a special tool, and my research has not come up with anything. Ram has apparently corrected the problem with an updated part, part number 68143491AB. Unfortunately, I cannot find anyone that has this new part in stock. As this is a safety issue affecting a lot of Ram trucks (check the forums and you will find a lot of people discussing the issue, so this is probably way underreported to the NHTSA), Ram should replace all 68143491AA with 68143491AB under a recall.

About a month ago the ABS and Traction Control warning dash lights started coming on intermittently with warning tone. They go on/off randomly or not at all some days. I had the codes pulled and there was only one, C0020-1 General ABS System Failure. This has not resulted in any dangerous vehicle incidents as of yet, but I must have my vehicle to tow/work and the expensive replacement parts are on indefinite back order. I understand this is a very common problem for 2017-2018 Ram HD trucks and Ram is doing very little to prioritize a solution.

I have a 2018 Ram 2500 - 6.7 Cummins diesel, The service ABS system and service electronic brake system dash lights come on and go off constantly. Every time they come on there is an alarm that goes off, and it also kicks the cruise control out. This problem started had around 32,000 miles and has continued to now 71,000 miles. I have tried multiple times to have this, diagnosed with a system reader with no luck. Have had the system reset also with no luck. I’ve read on multiple Dodge/Ram forums that this is an ongoing problem with 2017-18 and up Rams that they refuse to address. Any information would greatly be appreciated to get these problems resolved as it appears there are multitudes of people having the same issue. Thank You Note: The mileage on the pictures below is not when the problem started, these were a picture of the lights that I could catch in between them coming on and going off so I could show the mechanic what was happening.

I started getting a "service electronic braking system" message in the EVIC intermittently

The ABS module is bad. Can not drive the vehicle for fear the brakes will fail, especially when pulling a trailer loaded with animals (farm). This is ridiculous, a $86K vehicle with less than 40K miles (we have not driven the truck in over a year) because of a faulty part that the company will not own up to. PLEASE have MOPAR/RAM/Chrylser own up to this faulty part and issue a recall ASAP. When the brakes lock up and someone dies, that will be a real issue. Sincere thanks,

HYDRAULIC CONTROL UNIT FAILURE. While driving I encountered an emergency braking situation (deer in roadway) I applied the brakes and they did not go into an ABS slide/braking condition and upon applying the brakes, causing the brakes to lock up and the vehicle begin to change its direction, the dash dinged and illuminated the ABS and Traction Control light. After this incident the lights continued to flash on and off even while parked, and the brakes not applied. I was able to get to my home, I attached my scanner and followed the procedures set for diagnosis coming to the conclusion that the hydraulic control unit had failed. I was able to get it into the dealer on the 14th of September and they had concurred with me that the Hydraulic Control Unit had failed. There were no lights on prior to this incident to make me or any other driver aware that there was an issue with the ABS system. Chrysler has knowledge of this for there is a TSB (S2005000004) as well as a redesign of the part, 68143491AA to 68143491AB. Per the dealer the part is on national backorder until February of 2024. The vehicle is available for your inspection for I will not take it on the road with these faults risking mine or the safety of my family or others especially with winter right around the corner.

Service Electronic Braking System warning locked in. Service Electronic Stability Control warning locked in.

ABS module has gone out 3 times since I bought the truck new. Without the ABS system working properly the stopping distance could be reduced. Dealer has acknowledged the problem, saying they had a bad batch of parts but that seems to be incorrect. Looks to be a bad design with the number of these problems on these year model trucks. The dealer has already replaced the part twice and it’s gone out again, less than a year later. Warning lamp, message, and audio alarm cycle on and off intermittent but constant through a drive.

A few months after I bought this vehicle I started getting abs and traction control lights intermittently. Fast forward a year and it has progressed. Now while I’m driving every few seconds I get and audible chime and lights on the dash. This is constant and extremely irritating and distracting. It is also unsafe. I’m constantly driving which no ABS, no traction control and no cruise control. Ram obviously know this is an issue due to lawsuits filed against them and they have done nothing to fix the issue. You cannot buy a new part to fix it because they are “reengineering” the part. It was originally supposed to be ready to ship in august 2023. Here we are in September and they have pushed the date back to February 2024. Leaving all customer drying a 2017-2018 Ram 2500 with an unsafe vehicle and no option to fix it. We also can not trade the vehicle in as the dash lights up and chimes and no dealer wants an unsafe truck that cannot be fixed. A recall is expect at the very least

first evidence of a problem had to deal with the accelerator pedal A new pedal was installed. .The engine would start but only idle, truck would not move when put into drive .It had to be towed .Then it was something about a door sensor .It was replaced .Then the brake fluid problem started. It used 2 full quarts with no drips on the floor . Now I am told that the brake booster / hydraulic system Is the problem. This truck Has only 31,000 miles ,Not driven in the winter and looks like new . I am now afraid of the safety issues associated with plowing into another vehicle in a panic stop , The truck has been in the dealer (Jeff Wyler ,Canal Winchester, Ohio ) for nearly 8 weeks . It has been promised last Friday then Tues, then Thursday. Today is Friday and the service advisor (Jay or Joey) are not returning my calls. Please let know what I should expect . [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

HBU failed at 86,000 miles. Caused lose of ABS system, Traction control system, and cruise control.

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the brake warning light illuminated, and the "Service ABS" message was displayed. The vehicle was taken to an independent mechanic to be diagnosed. The vehicle was diagnosed with ABS failure, and the contact was informed that the ABS module needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact that parts would not be available until March 2024. The failure mileage was approximately 45,000. The VIN was unavailable.

Mileage: 45,000

ABS AND TRACTION CONTROL LIGHT ON. THIS IS A WELL KNOWN ISSUE WITH THE RAM 2500 YEARS 17-18. I PULL A TOY HAULER WITH 2 MOTORCYCLES IN IT. THIS IS A 28 FOOT TRAILER. I DID NOT NOT GET IN AN ACCIDENT BUT I HAVE NO TRACTION CONTROL OR ABS AT THIS MOMENT. TIRES WILL SPIN VERY EASILY IN THIS TRUCK IN THE RAIN. HAD THE BACK END STEP OUT LEAVING WORK CROSSING TRAFFIC AS I HAD NO ABS INTERVENTION AND IT WAS COMING OFF OF A BIG HILL. THE DEALER SHOULD BE COVERING THIS. I HAVE AN APPOINTMENT TO HAVE IT LOOKED AT AND WAS TOLD THE ABS UNITS ARE ON BACK ORDER TILL FEBRUARY WHICH MAKES PERFECT SINCE BECAUSE THEY ARE ALL FAILING. HOPEFULLY BY THE TIME I HAVE MY APPOINTMENT THIS WILL BE COVERED AFTER READING ABOUT THE LAWSUIT AGAINST THEM. APPARENTLY THEY RECALLED THE 19-22 VEHICLES FOR THE SAME ISSUE.

In July of 2020 the service alarm went off for my electronic braking system and ABS. I took it to the local RAM dealership and they replaced the Hydraulic Control Unit for the ABS System (not covered under warranty). Now, in August of 2023 I am again having the same service alarm for the electronic braking system and ABS sporatically occur. I have not yet taken it back to the dealership, but in my search on YOUTUBE, this appears to be a systemic problem that the manufacturer is not addressing.

The ABS light came on and went off intermittently, which also disabled the cruise control when the light was on. Eventually the light stayed on. Most recently the start button quit working properly. We have had it at the dealership twice with no results. We have talked to the dealership many times and been getting the run around. The latest was today and was told the parts are back ordered until 2024. They have not given us any paperwork because we do not have to pay. We also have and had the radio (main computer) replaced a couple of times and the screen still blinks randomly.

ABS and Electric Braking System - multiple failures.. 1st time system failed at around 24k miles, was reported and fixed under warranty, 2nd time same system failures at around 76k, same errors and same results.. will have to be repaired under owners costs.. Seems this is a 'known issue with a NTSB" but Ram still not owning the issue.. This part plays a huge role in the safety controls of the truck.. They are designed and built to pull heavy loads and the braking and traction controls play a huge role in the safety traveling of these vehicles..

The ABS warning light comes on and off continuously while driving the truck.

My truck has had a recall done on the ABS system. After the recall I had another problem with the ABS system where the ABS and traction control warning lights and chime came on and then off. This condition was very distracting while driving!! It eventually stayed on all the time. My cruise control did not work and I imagine the ABS braking system didn't work. All the time the dealer was saying there were no parts. I found another dealer and had to wait a few weeks and they replaced the ABS HCU and hydraulic unit. This was in 2022. It is now 9/13/23 and it is starting again!!! I am going to take it back to the dealer and hope they finally will resolve the problem. ABS brakes have saved many lifes. This problem needs to be fixed. There are countless concerns on the internet of this problem with RAM trucks, apparently 2017 and 2018 are the most affected. Please put some fire under FCA/RAM and help get this problem repaired.

ABS/traction control failure. This also disabled cruise control causing rapid deceleration at set highway speed. Getting repeating chime and check ABS and traction control warning messages. ABS module and HCU were replaced under warranty at under 11,000 miles for same symptoms. Truck now has just over 45000 and read ABS codes indicate that part has failed again. Part seems to be backordered or unavailable from dealers.

ABS/traction control sensor issue. I believe it to be a faulty sensor or sensor connection issue which is causing my service brake light to chime and light up at every bump in the road. While driving even just a short distance my service brake light/alert chime goes on and off sometimes every 2-3 seconds and while driving on the freeway my cruise control disengages every time the brake warning pops up. Upon researching this issue I've found thousands of Dodge Ram owners complaining of the exact same issues and dealerships are suggesting they know nothing about this problem.

ABS system failure, recirculation pump failure, code C0020, Ran off road while ABS and traction control was off during wet conditions. Unsafe to drive due to safety failure on ABS.

FOR THE PAST MONTH A WARNING LIGHT ILLUMINATES AND DINGS CONTINUALLY INDICATING AN ABS FAILURE AND NEED FOR ELECTRICAL BRAKE SYSTEM SYSTEM REPAIR. I CALLED THE LOCAL DEALER THAT WAS RUDE TO SAY THE LEAST AND INDICATED THEY KNOW THIS ISSUE WHICH IS VERY COMMON AND REQUIRES PARTS (ABS CONTROL UNIT HCU-HYDRAULIC CONTROL UNIT) THAT ARE ON BACKORDER AND WILL NOT BE AVAILABLE UNTIL NEXT YEAR (POSSIBLY FEBRUARY OR MARCH). THEY STATED IN CASE OF EMERGENCY BRAKING AND PARTICULARLY ON WET PAVEMENT OR GRAVEL THE BRAKES WOULD FAIL AND THE TRUCK SHOULD NOT BE DRIVEN. I SEARCHED THE WEB AND CLEARLY THIS IS A WIDESPREAD PROBLEM OF A PART/SYSTEM DEFECT. I AM LEFT IN A POTENTIALLY HAZARDOUS SITUATION WTH NO RECOURSE AND NO VEHICL TO DRIVE. I APPRECIATE ANY HELP YOU CAN GIVE ME AND OTHER RAM OWNERS.

Reoccurring Electronic Brake System Failure message along with ABS and Stability Control faults, dealer unable to fix due to supply issues. Ram is supposedly waiting on a redesign, but until then I have a safety compromised vehicle where abs and traction control don't work.

ABS , traction lights are on and cruise control , ABS and traction control doesn’t work. Safety issue. I understand that there is a recall on 2019 , 2020 models and wondering why the 2018 ram 2500 are not included in the recall .seems like a common problem says the dealership.

While driving on a smooth paved road the service anti-lock brake system and service electronic brake system lights started flashing on and off. This continued for several minutes and then randomly stopped. On my return trip home after about 10 minutes of driving on the same smooth paved road the service antilock brake system and service electronic brake system lights started flashing on and off again. Once again the service lights randomly stopped on their own while continuing driving.

My truck is at approximately 35,000 miles. It recently started notifying me that the Anti-Lock Braking System and the Traction Control need to be serviced. While researching, I noticed that there were numerous reports of drivers with the same issue on forums related to Ram trucks. It appears that this is a very common issue that has not been addressed by Ram.

Anti-loc braking system, and electronic braking system issues. Modules needed. Ram has back-ordered them for months. There appears to be a class action suit starting, What is NHTSA doing?

ABS module or HCU bad. Anti lock brakes not working. Cruise control not working. 4WD not working. Caused issue driving with a load when ABS did not engage and almost rear ended another vehicle.

An ABS system that was designed to save other people. And your life is now not operating functionably. And putting me and other people in danger. Or else why would they have made it way back in the day? Receiving vehicle message of serve ABS braking system. Code C0020-01. Dodge knows of the issue and needs to recall and repair.

Abs modular gone bad

abs brake failure the hcu fails causing warning to service abs problem first occurred 2 years ago had hcu replaced problem is back again these hcu units were defective from the get go ram knows units are defective this is a safety issue and needs to be resolved your help is needed on this safety issue.4/12/

C0020-01. Electronic Braking System and stability control system continually go in and out of alarm kicking the truck out of cruise control suddenly. This was repaired once under warranty by replacing the hydraulic control unit at 40,000 miles and it is now doing the same thing again at 90,000 miles. This is a significant safety issue as it prevents the use of cruise control and turns off the stability control system on the truck. The parts to repair the system are not available due to them being in “Engineering Review” until 2024. The only guidance from Ram was to continue driving the vehicle until parts become available.

SERVICE ELECTRONIC BRAKE SYSTEM NOTIFICATION TURNS ON INTERMITTENTLY, CRUISE CONTROL DOES NOT WORK DURING THIS TIME

ABS module

ABS warning light goes on and off at intermittent times. Message says service ABS brake system. This truck has not been inspected yet but there is a class action lawsuit and NHTSA investigation on-going for this problem.

My 2018 RAM ABS warning indicator light goes on and off continually. It started last year but now it's on constantly. I did some research, and this seems to be a very common issue with this model of RAM truck. Unfortunately, the dealership has informed me there is no recall on the item and cost to repair are over $1,000. So I'm driving with no ABS brakes most of the time. With the light and warning noise constantly going on and off is very distracting while driving. Not a very safe problem to have while driving.

ABS / Service Electronic Braking System lights constantly dinging on and off while driving my truck. Cannot get parts for repair.

I get an error message on the dash that says "service electronic braking system" and "service ABS”. Ram dealer has stated that the truck needs a new ABS modular and ABS pump but the parts are on back order until February through Chrysler.

ABS system failure causing spinout and skidding. System failure spurratic.

I had my HCU pump fail 3 times previously(68143491AB, HYDRAULIC CONTROL UNIT Anti-Lock Brake System), now the dealer is telling me that I need to buy another module (68347098AB Module, Anti-Lock Brake system Electronic Stability Controller) in addition to the failed part for them to repair my vehicle (Tech told me its on a service bulletin, although my unit is not bad). The dealer told me if I got the parts they could repair my vehicle, so I bought the HCU. Shortly after they said a technical bulletin is telling them that they need to replace an additional module when they replace the HCU, which is not available until February 2024. If they diagnose my truck (which they did), and provide me with a receipt I would have to pay the diagnostic fee of $160, and they would not be able to release my truck until the repair was made. I can not have my truck at a dealership for 5 months waiting for a part to be available. Is there anything that can be done about this? I do trade shows and need a truck to carry my products.

Similar to the 2019 & newer Ram HD recall for the ABS electronic control module, my 2018 Ram 2500 has the same issue. It was recently diagnosed at the dealer in August 2023, but due to the abundance of impacted trucks, the dealer estimates that replacement parts will not be available until at least February 2024. While I wait for the repair I have no ABS, traction control, stability control, or cruise control. I drive the truck approximately 750 to 1,000 miles per week and have a 3,000 mile vacation planned in October. This translates to driving the truck approximately 15,000 to 20,000 miles without the above noted safety features. I believe my truck should be added to the recall, and RAM needs to step up and provide faster repairs.

Truck is showing service message "Service Electronic Braking System" and "Service Anti-Lock Brake System". Service message comes and goes constantly, chiming and making cruise control unusable. Several times I have almost had a collision on the interstate because the vehicle will drop out of cruise control expectantly. I have researched the issue and the required replacement parts are on national back order until Jan/Feb of 2024. So not only do I have to listen to the dang chiming noise, I don't have fully functioning ABS or Traction Control. This is a serious issue that RAM needs to deal with. I know an investigation is underway already: Preliminary Evaluation PE22-012. Please add my complaint to the growing list of RAM owners facing this serious issue.

ABS control module is malfunctioning for the second time. Was replaced at approximately 25000 miles. Now is failing again at 48000 miles. ABS braking and traction control is affected.

Anti Lock Brake code appearing while driving. Have had the Anti lock brake module replaced once before. This is a common issue in 2018 models and Ram refuses to address.

Abs and traction control lights come on and off cruise stops working

Service ABS electronic brake indicator light continues to illuminate on various occasions. Dealerships has no answer for issue

My original ABS HCU pump has been replaced 2 times, and now 11 months later it needs a 3rd one. First one went at 60K, second one 93K, 3rd one at 120K and now I do not have ABS, Traction control or cruise control.

The ABS module and/or HCU on my truck is bad causing me to lose ABS functionality. The ABS light comes on and a tone alerts me to the problem. This normally happens randomly, and the problem comes and goes. The cost to repair looks to be around $1600 from the dealer. With this being such a safety issue, it seems reasonable for a recall to be put into place to address the issue. The issue is further complicated because there is a new and improved version of these parts, but the new parts have been on backorder.

My abs keeps going on and off repeatedly. This is what I have read in many forums. I don't understand why there hasn't been a recall for the part. The module is flawed and I believe there is a class action lawsuit. Apparently there is a back order until 2024 and I do not wish to put the same broken part in my $70,000.00 truck! I just want my truck fixed.

ABS system keeps failing. Loose ABS, traction control, and 4 wheel drive. Part has been replaced 3 times already. 4th part is having issues

Abs light comes on when under hard braking or traction control is used for slippery conditions

62,000 miles, "service anti-lock brake system" and "service traction control system" lights are on, no ABS, no traction control and no cruise control.

Service braking locking system. Intermittent ping of of abs/ebs traction control display lights. Cruise control will not work and shut off when this has been activated.

ABS light and Brake controller light comes on and off constantly.

ABS warning lights came on took the truck back to the dealer (approx 54000 miles) replaced abs pump unit and would not cover under warranty as it was out due to miles. Now again at 108000 I am getting abs warning and electronic brake system warning This is clearly a repetitive brake safety issue and a recall should be enacted

My ABS Module and Hydraulic Control Unit (HCU) Part Number 68143491AA seems to have failed and it seems as it is a very common problem which needs to be addressed by RAM. My ABS is not working, my traction control is not working, and my cruise control is not working. While I drive it constantly goes on and off and chimes over and over and over. This is VERY dangerous to not have the braking or traction control not working and is putting me and my family in danger. This needs to be a recall. Not to mention the part that needs to be replaced is on national backorder and you can't even get it. Please help.

For the third time in 37000 miles the abs system including ABS system and electronic brake system has failed. This has been repaired around 15000 miles and recently at 35000 and it went out again at 37000 miles. Didn't last 2500 miles after last repair. When this happens trailer brakes quit functioning and cruise control also quits working as well as every few minutes the system gives you a continuous warning chime. From checki9ng a few web sites this seems to be an on going problem on the 2018 trucks mostly but a few 17s. Last info I have is parts are not avail for repairs until at least 2/24 and then only maybe. The truck is unsafe to drive especially when towing a larger trailer. This needs to be made a recall for safety concerns. I had to trade off my truck due to how I use it and no expectation for a repair time or date.

ABS brake failure/ loss of anti-lock brakes, cruise control, and traction control

In October 2012, my 2018 Ram 2500 had issues with the brake module and ABS system. The truck had 49000 miles when the system intermittently displayed messages to service ABS system. A trusted local mechanic checked and found a service bulletin about the issue. I had him replace the brake module and master cylinder. I then had a Chrysler dealer reprogram the module. My costs was approximately 800 dollars. Now it is summer of 2023 with 65000 miles and the same issue is occurring. I think it is time for Fiat Chrysler America to step up and make these repairs. It is dangerous to have this situation. It affects cruise control, four wheel drive, and of course negates having ABS. I need this truck and cannot afford to park it.

The ABS and Traction Control light comes on. The cruise control is disabled when this happens. Vehicle only has 17k miles but issue started at 16.7k miles. On dry pavement not an issue but on slippery roads and ice and snow this could be a possible cause of an accident. In May I tried to order the ABS control module and Hydraulic Control Unit and was told by the dealership it would not be available until August. I contacted the dealership and now they are telling me late September but more than likely will be later. I was told Dodge is doing an engineering review on these components and that will not be completed until February 2024. According to my research the high failure rate is cause for concern and no parts availability complicates the issue. Why has a recall not been issued by the manufacture. Obviously something is going on with these parts. Should the engineering review by Dodge result in component redesign, I would want to hold off until redesign parts can be obtained. The vehicle is derivable but with winters approach safety concerns should prompt the NHTSA to do something about this issue.

ABS and traction control lights on at 35K miles. Result is less responsive braking. Has only been driven in dry conditions since occurrence. Repair has not been completed yet. Contacted manufacturer and will not compensate for repairs as vehicle is out of warranty. The contact wanted to include the error code shown on their vehicle - C0020-01: ABS Pump Motor Control - General Electrical Failure.

Antilock Brake and Traction control warning lights alert with dashboard message intermittently notifying to "service electronic brake system" and "service antilock brakes". Warnings come and go and may stay off for several days. When in warning mode, cruise control is de-activated; either shutting off, if set, or not allowing use. Dealer repaired by replacing pump control module (part#68143491AB) at a total cost of $683.19 for parts and labor. Odometer mileage at time of event was approximately 76,600 miles. Dealer indicated that this was a very common problem. Truck should be recalled and repaired at manufacturer's expense.

ABS and traction control blink off and on and the cruise control doesn’t set. I was told by the dealership that they cannot keep the ABS control module in stock because they are constantly changing them out. This issue really needs to be addressed because it is a very important safety issue when the ABS system doesn’t work properly.

ABS TRACTION CONTROL BRAKING ISSUES AND DANGER. ONLY HAS 24K MILES GARAGE KEPT

Driving down the road. ABS light and traction control light will flash and cruise control and 4x4 will not work

Started recently getting an anti-skid warning with a chime. I took the truck to a nearby mechanic to read the code, he said the antilock brakes were bad, and suggested taking it to a dealer. I took the truck to the Ram dealership in Mineral Wells TX and the dealer confirmed the code. I have talked with 3 different Ram service departments and they all tell me the parts will not be available until next year. Why should I drive an unsafe vehicle, because the manufacturer cannot supply parts?

ABS and/or traction control lights turning on intermittently while driving

ABS system doesn't work. Was inspected by NAPA Pugh's Car Care Center. My safety is at risk because the brakes do not work correctly. Warning lights are on. Appeared March 2023.

Same part needing replaced for the third time (control anti lock brake system 6814349AA) at 12k miles 28k miles now at 42k. Asked if this is a common issue and ramcare adviser said that he didn’t know but found a lot of info on similar issues and advised to file a report

Vehicle started displaying “Service Electronic Braking System” and “Service Anti-Lock Brakes” intermittently and rapidly, during normal driving. Problem appears at random, and when it happens, the cruise control cuts out causing loss of speed. Truck shows code C0020-01 with an ABS code reader, meaning that either the Hydraulic Control Unit or Anti Lock Brake Module (or both) require replacement. Upon researching repair, I have found that this is a very common problem with these trucks, and that there is a possible NHTSA investigation into this, as Ram is very aware of the problem (as evidenced by their responses on forums discussing this problem) but has not issued a recall.

Issues with HCU/ABS system. Electronic braking system goes in and out intermittently rendering ABS/traction control inoperable. Existing known issue and original OEM HCU has been discontinued as a result.

I purchased my vehicle on 6/25/2019. At 951 miles on 5/11/20 my ABS system went out and was replaced under warranty. At 11917 miles on 9/17/21 my ABS system went out again and was replaced under warranty. Now at 37605 miles my truck is intermittently having my ABS system going out which eventually it has gone into total failure. My truck is now out of warranty.

My ABS and traction control dash lights came on and lost cruise control while towing my RV. I fear of someone rear ending me when loosing CC. The alerts intermittently go on and off.

While driving on interstate, Abs system went out, and as a consequence, the cruiser control also failed unexpectedly. Vehicle has less than 60,000 miles on odometer. Per review of this issue on the web, there is currently a class action lawsuit against Stellantis regarding this particular issue. Moreover, there is plenty of data to suggest that replacement parts also fail in short order…within the warranty period of the part. Problem was reproduced…problem was recurrent…problem was verified…by dealer. Warning caution messages were presented on the instrument cluster. Dealer ordered replacement HCU (hydraulic control unit). In the interim, dealer said vehicle was safe to drive. The very next day after picking truck up from dealer…while waiting for HCU part to arrive and be installed….By sheer coincidence, or directly related, I lost almost all brake pressure within 3 weeks of first receiving the abs fail message…while driving on the interstate. I didnt know of the diminished braking until I began to exit the interstate at high speed. Very, very dangerous situation….brake pedal to the floor…and much distance required to get the truck to a stop. Fortunately, no other vehicle was in my path as I tried to get the truck slowed and stopped.

ABS/TRACTION CONTROL, 2ND TIME in 55K MILES. 1ST SET REPLACED UNDER EXTENDED WARRANY. NOW PARTS UNDER DESIGN REVIEW - UNAVAILABLE. I NOW HAVE NO ABS/TRACTION CONTROL! HELLPPPP

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE

2018 Ram 2500 Power Wagon 6.4L service electronic braking system displays on dashboard the abs and traction control lights turn on as well. The messages display quickly then disappear been intermittent now issue is happening on a regular basis. dealer stated that warranty does not cover abs module and according to them the display message is "NOT A BIG DEAL". I advised them that I have two toddlers, and this is my daily vehicle and getting that kind of message from a "DEALERSHIP" is very upsetting and very unprofessional. They are advising me that the vehicle will operate fine but I won't have anti-lock brakes if I press on the brakes quickly. To me this error message "IS A HUGE DEAL AND SAFTEY CONCERN" not only for me and my family but all the other families on the road traveling.

Abs pump motor control/Yes. unknown. unknown. unknown. Yes, continually blinking and dinging abs light (SERVICE ANTILOCK BRAKE SYSTEM) (SERVICE ELECTRONIC BRAKING SYSTEM).

ABS/Traction control lights come on shuts your cruise off light flashes and dings constantly It is a safety issue that needs attention plus parts are not available

I am experiencing problems with my ABS & Traction Control system. This is the 3rd time I have had this issue with my truck since I purchased it new in 2018. The truck only has 56k miles on it. ABS/Traction control is definitely a safety issue due to brake not functioning properly as the truck is designed to do. Dealer says there are no alternative parts that can be installed & there is no recall. This is a rather costly replace/repair. Why is RAM not doing something to address this issue? There are forums online that say this is a known issue. Some state that RAM recalled some selected trucks, but my truck does not come up for the recall. THIS NEEDS TO BE ADDRESSED. ABS IS SOMETHING YOU DO NOT WANT TO FAIL IN RAINY CONDITIONS. WE SHOULD NOT HAVE TO MAKE THESE REPAIRS TO OUR ABS SYSTEM EVERY COUPLE YEARS. THE CODE COMING UP IS: C0020-01 - ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE.

Received a service ABS anti-lock braking system. Seems to be the HCU part #68143491-AB or module part #68347098ab

ABS light and traction control light came on. Upon scan tool the code was general electrical failure of ABS system. I call my local ram dealer and they inform me of multiple failures of the HCU on 2017 and 2018 ram trucks. This is a safety hazard for my self, my family, and others. Theis desperately needs to be a recall on the ram trucks. This is very dangerous. Also the ram dealer talks of at least a 6 month lead time for this part.

ABS hydraulic control unit failure. Took the car to dealer to resolve issue 6 months ago and was told part would not be available till august, come august called again to check status on part and have now been told it won't be available till February. Abs does not function, cruise control does not function, Warning message and annoying chime appear on dash every 30 seconds while driving saying abs failure/ebs failure. Vehicle is unsafe to drive and no fix has been made, I will have been without the vehicle for about a year come February, absolutely ridiculous

ABS & Traction control light keeps coming on. Believe this is a safety issue. My research has shown this to be a major problem with vehicles like mine and the parts are not available. My family and I use this vehicle to tow a camper and I feel that the manufacturer should issue a recall and repair since this is a known safety issue. This started approximately one month ago and is continuing to get worse.

Service electronic brake system and ABS system

I purchased the subject vehicle in NEW condition in September 2019. On April 2021 the vehicle ABS lights came on and off. The mileage of the vehicle at that time was 16,538. I took the vehicle in to get serviced by ANCIRA Chrysler Jeep Dodge Ram dealership and the HCU PUMP was replaced. I have the service invoice that has all this information. On August 20, 2023, the same lights came on. The vehicle now has 48,000 miles on it. As a part time mechanic, I conducted a diagnostic test and found that the error code is the same as the initial incident, which is Code C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRIC FAILURE. The vehicle no longer as a warranty and since there are no available parts available for repair, I have no choice but to drive this truck putting myself and my family in danger. The vehicle is available for inspection if needed.

ABS and Traction Control warning lamps lit with chime. Vehicle scan shows abs pump failure, confirmed by an independent service center. Loss of antilock braking, traction control, and cruise control.

ABS traction control, light code c0034

Service electronic braking system light comes on intermittently every 1-5 minutes while driving. Also, a light indicating issues with the traction control system comes on. ABS system seems to be failing or indicating failure almost constantly. Cruise control is disabled during these times. I've read this is a common problem with these vehicles. There really needs to be a recall issued for this. Is my truck safe to drive if the braking system functionality is in question? Not really.

My ABS and Traction control lights activated visually and with audible alarms. I brought it to the dealer. It only has 23,000 miles on it with a manufacturer extended warranty. The dealer told me that the ABS pump motor control as well as the HCU has failed and need to be replaced. They also told me that the parts are not going to be available until the EARLIEST February of 2024. The vehicle is not safe to drive without these safety systems working especially towing. They told me the parts are under Engineering review. They suggested I park the vehicle until parts are available. NOT ACCEPTABLE!!! I have looked at owner forums and this issue is common and needs to be addressed by NHTSA and the vehicles recalled due to safety.

Service ABS system and traction control light continually flashes on and off. Does not allow me to use cruise control and it also turns off my ABS which is unsafe.

Abs system lights keep coming on even without system needing fixed.

The service anti lock brake system light is on, the service electronic braking system light is on. This causes the ABS, traction control and cruise control not to work.

The “service electronic braking system” light is on, also the “service antilock brake system” light is on as well.This causes the ABS, traction control, or cruise control to not work The truck has 49,000 miles

ABS failed, brakes locked up causing truck to skid out of control

My vehicle keeps throwing up a service ABS and service electronic braking system intermittently and the braking system is greatly diminished. Vehicle has been inspected and the replacement parts for the breaking system are on national back order without a recall open.

My ABS / Electronic Stability control warning lights keep coming on intermittently and also sometimes staying on for hours at a time. I cannot use my cruise and my ABS will not work with these problems making this a very dangerous truck to drive. I have read that there are many other trucks with this issue. More specficially the 2017-2018 Ram 2500's. I believe there should be a recall for these parts as this is a intergral function in these HD trucks.

ABS module and HCU module are at fault. Have been driving it and lights and dings will come on and off at random. When lights are on I cannot use electric brakes for my trailers either. Dangerous when I’m hauling live horses and no trailer brakes. This is a common issue that Chrysler refuses to recall.

Abs HCU failure. This is a know common issue and yet no recall. THIS IS NOT SAFE

The HCU and ABS modules are defetive. This has been a safety issue as the ABS system is inoperable. The parts are finally available. However, it will cost $2000.00 for repairs since the vehicle is out of warranty. Should this not be a recall?

Ram 2018 ABS pump failure. No abs, no traction control. Dealer states no parts until,maybe, Feb 2024. Service manager stated do not drive as brakes could/may totally fail. Web search shows common issue with 2018 Rams.

"Service Electronic Braking System", & "Service Anti-Lock Braking System" indicators flash & ding constantly. Started on 8/15/23. Vehicle can be available for inspection. It has not been inspected by a licensed mechanic yet. ABS, & Traction Control lights on the cluster are lit up.

Drivers side battery died, after replacement of the battery, the ABS ,traction control lights came on and off with display of "service ABS system" in the display center. this has continued to flash with audible warning ever since battery replacement.

ABS and Traction Control warning lights on dash, go off and come back on. Truck was in cruise control with exhaust brake on and tow/haul mode engaged. ABS/Traction control light flashed on, truck dropped out of cruise control, exhaust brake came on car following the truck almost collided with my rear bumper. This is a dangerous situation, it is also affecting the cruise control. The dash board ABS and Traction control light cycle on and off, however this last few days they have been on more than they are off. This needs to be fixed at no charge by RAM trucks.

Anti-lock braking system and Hydraulic Control Unit were replaced on my truck. The original parts are defective, and many owners of 2017-2018 Ram 2500 and 3500 trucks have had the same issue.

My Vehicle along with thousands (maybe hundreds of thousands as I have been looking on internet ) has antilock brake warning buzzer on that will not go off and I only have 25000 miles on it. It is out of warranty with Ram but I know this should be fixed as I am Leary to drive a vehicle with a brake warning light and warning buzzer constantly going off while driving. If the brakes fail these trucks could kill someone or kill the driver when they cannot stop.

ABS / traction control intermittent failures.

"Service Anti-Lock Brake System/ Service Electronic Brake System light continues to chime. Mechanic has inspected, cleaned, and die-electric greased the connectors. Light stays off until the first bump. It is unknown if the ABS is operating properly and may lead to accident or death if not corrected.

My truck is getting a periodic message to service the ABS system as well as the Electronic Braking System. After doing some research, I see that RAM is the defendant of a class action lawsuit over this issue and the NHTSA is doing an investigation into several people having these issues. I took my truck to a dealership -- they said my truck needs an ABS control module and brake control module. However, the parts are not available and Ram does not know whey they will be available. The dealership told me it could be six months or more before parts are available but my truck "should" be safe to drive. I own this heavy duty truck because I tow a travel trailer. I cannot tow anything with a vehicle that has a failing braking system.

Service abs system, abs light and traction control light flash on and off intermittently indicating possible faulty HCU and ABS Module installed from factory causing the abs system to fail along with the traction control system and loss of cruise control . My safety and others are put in danger with the brake system not being allowed to work properly

ABS light/service electronic brake system. Dealer advised that ABS actuator and hydraulic controller unit needs to be replaced. Items are on back order and can not be ordered until released by Chrysler in February 2024. In the meantime no one can tell me if it is safe to drive my truck or not.

Service Electric Brake System is displayed and ABS light on. Truck only has 52045 miles on it.

The ABS and traction control light is flashing on and off, this truck has 57000 miles on it and is garage kept. I looked it up and many of these trucks are having the same problem. The dealer wants $200 just to verify the problem. It is unreasonable that the ABS system fails so quickly in these trucks. The ABS/traction control lights will also come on and stay on for a while and then go off.

This is a common problem I’ve replaced the abs pump once already on this truck and it’s failed again!!

Abs lights are coming on and off I took to a shop where they told me it's known problem and parts are on backorder

Service electronic braking system message, ABS light and traction control light are on. Code:C0020-0. ABS HPU problem. This is an obvious issue with these year make and model of trucks.

The contact owns a 2018 Ram 2500. The contact stated while driving at various speeds, the Service Electronic Brake System was displayed, and the ABS, Traction Control and cruise control became inoperable. The vehicle was taken to the local dealer who diagnosed that the Hydraulic Control Unit had failed and needed to be replaced; however, the parts were not available. The contact stated that the failure had made the vehicle extremely unsafe to operate while towing heavy loads. The manufacturer was also notified of the failure. The failure mileage was 1,025.

Mileage: 1,025

The contact owns a 2018 Ram 2500. The contact stated that the Service Brakes message was displayed and deactivated the cruise control and caused the stability and traction control systems to fail to operate as needed. The failure wase self-corrected; however, the failure recurred shortly afterwards. The failure persisted. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 78,000.

Mileage: 78,000

The abs and traction control lights stay illuminated on dash. No abs, traction control, or cruise control. Abs module looks to be the problem

Antilock brake controller malfunctioning. After a quick google I see this is a a very common issue so I’m confused as to why it’s not a “recall” item. Thanks for your assistance.

Faults for the ABS (anti-lock brake system) and EBS (electronic braking system) have been coming on intermittently for a couple months. Now the faults are permanently on indicating the ABS and EBS needs serviced. The fault code is c0020-01which indicates the known malfunction involving the anti lock brake system module and anti lock brake system control. While these faults are present the cruise control also doesn’t work. This is a well documented and known issue with certain model years Ram 2500 and 3500. My truck had approximately 57,000 miles when the faults began.

ABS and SERVICE ANTI-LOCK BRAKE SYSTEM warning lights randomly turn on while driving and cause loss of ABS braking and traction control, this is dangerous on slick roads.

ABS failure warning light comes on randomly. While it is on, cruise control is disabled. RAM dealer examined truck and determined HCU pump needs to be replaced, but the manufacturer will not allow them to order this part as it is on "engineering review" until at least February 2024. Called RAM Care and they said "there is nothing we can do". When pressed for where to take my appeal to, the only further contact given was a PO Box in Michigan. Not being able to drive a truck I paid $75K for seven months is unacceptable!

ABS and Traction Control warning lights randomly and routinely illuminate causing loss of ABS braking and traction control, and loss of the cruise control function.

ABS light comes on screen along with traction control. Immediate loss of cruise control while traveling 70 MPH pulling 10,000 lbs on a highway. If brakes go on that everyone's safety on the road is at risk. I have not had it to dealer but have had a mechanic put his code reader on it. Warning lamps for this were the ABS light and traction control light.

ABS and Tracton control

Beginning in October 2022, the vehicle began displaying "service anti-lock brake system" along with a chiming sound and the traction control light comes on. Cruise control is disabled when this is displayed. I went a dealer while out of town and they said they were well aware of the problem, but the part is unavailable. When I returned home I went to my local dealer and they confirmed being aware of the problem in this year/make/model vehicle, but the part was unavailable. They stated the part would be available in August 2023. August is here and the part is still not available. This is an inconvenience due to not being able to pull my travel trailer or any trailer. This is also a safety concern since I don't have anti-lock brakes. This vehicle has 39000 miles on it. Bought new and sits in a covered garage when not in use.

ABS and traction control lights warn on dash and chime. Very intermittent and my truck only has 14,749 total Miles on it. I understand most of us with 17/18’s have this issue. I don’t feel safe having intermittent use of proper braking as we pull trailers with this vehicle. It’s the entire purpose we bought it. Dealer will not repair under warranty. Need a recall. Repairs cost thousands on these low mile like new trucks.

anti lock brake system failure, has been inspected by dealer and at dealership now, unable to repair as parts are not available for replacement. The dealership will not even try to put thru extended warranty really be hush hush about this issue. The vehicle can be inspected anytime. There where no warnings signs just started one day with the messages and lights flashing. This should be a recall before total brake failure.

The service electronic braking system and service antilock brake system are having intermittent flashing sometimes it stays on the whole drive. When it does this sometimes the brake pedal will go past the normal range for braking and go almost to the floor before it starts to engage the brakes. After reading several forms this seems to be becoming a common thing the fix is the ABS module and the hydraulic control module. What component or system failed or malfunctioned, and is it available for inspection upon request? Yes these parts are available upon request they are still in my truck. How was your safety or the safety of others put at risk? Brakes are not properly working could result in an accident with just myself or many others as I drive mostly highway. Has the problem been reproduced or confirmed by a dealer or independent service center? No it has not been reproduced or confirmed by the dealer. I seem to have a lot of incompetent dealerships/mechanics through my dealings with them having mis-diagnosed my other vehicles consistently. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has not been inspected by anyone. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes there are warning lamps, messages indicating these issues. There was no other problems prior to the failure. I believe it started on 27 July 2023.

ABS failed, cruise control and traction control are inop as a result. The risk is loss of ABS when traveling, especially on wet or snow and ice covered roads. It has not been inspected by a mechanic. The failure light is on in the dash cluster and I have clearly lost traction control and cruise control. This began on July 31, 2023.

Warning lights for service ABS system and service Electronic braking system started coming on intermittently sometimes staying on for extended periods. While the warning lights are on I loose ABS braking controls which could cause the brakes to lock up in an emergency braking situation causing the lose of control that would effect my safety and the safety of others with me or in the emergency situation. I also loose my cruise control function. Code for the alarm is C0020-01 (ABS pump motor control electrical failure).

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE is the code that came up after the dash start flashing between service ABS and service electronic brake system. The TSB says to replace the HCU and the ABS module after checking each one. I wasn't driving far, so it did not affect my safety. I have parked the truck until I can get it fixed. The problem was identified by using a friends code reader and researching several online forums. It has not yet been inspected by anyone else as I have been trying to find the parts and they are on national back order. The one dealership stated they are on national back order until FEB 2024 due to engineering review. Prior to the warning lamps, I did notice that it felt like my front driver side brake was holding the rotor after I would release the brake and start to accelerate.

my vehicle and hundreds of other owners are having bad HCU/ABS units that turn OFF the ABS and traction control on our ram 2500's.

ABS warnings on dash. Error code c00020-01. Traction control, cruise control disabled.

Abs/ traction control light comes on and off lose all cruise control. Get code c0020-1.

At around 50,000 miles the ABS light started coming on. This affects traction control and speed control. Dealer said it was the ABS Control Module and is a known issue but not a recall. Finally repaired at my cost of $ 1,103.32. st 57,377 miles on 9/13/2022. Less than 12 months later it is doing it again on 7/29/2023 at 69,649 Miles. This seems to be hazard as the ABS does not work or traction control. Also cuts off the cruise control when it occurs.

ABS modules and hydraulic control unit (HCU) module failure with around 60,000 miles on the truck. My antilock brakes and traction control will not operate. The dealer has confirmed this is the issue. The lights were flashing on and off and finally just stayed on

The abs pump and module are bad and there is no replacement parts available through ram. The truck only has 32k miles. They say the parts are on back order. The truck has no abs function nor does it have vehicle traction control. This should be a recall as it’s happening to thousands of trucks. This is a blatant safety violation. Yet the new trucks are still being built with these parts that are somehow not available.

Intermittent Abs Failure. Kicks off cruise control and looses ABS brakes and traction control. Very dangerous. Lost this ability while pulling my RV Camper on wet roads. Went into other on coming lane do to sliding and skidding. I guess this is a very well known issues with no recall or information from Mopar\ Ram to the owners. This almost killed me My wife and my 3 year old grandson.

Lights keep coming on for ABS System Check and Electronic Braking System check. Doing research online there are thousands of ram 2500s with the same issue. They keep appearing and then disappearing starting happening July 24th 2023 at around 57,000 miles. I have a appointment with the dealer set up but they can't get me in till August 16th. I'm worried while towing my camper or driving with my family our breaks won't work due to a known issue with these trucks.

Driving home from work, ABS and traction control light and warning started to go on and off nonstop every 2 seconds or so. No bumps on the road or excessive turning just a straight highway.. will contact dealer today for any recalls but I don’t see any open.

I WAS DRIVING DOWN US 19/27. THE ROAD WAS WET AND A DEER RAN OUT IN FROUNT OF ME. WHEN I APPLIED BRAKES MY TIRES LOCKED UP AND I SKIDDED OF THE ROAD. MY ABS LIGHT STAYS ON AND EVERY TIME I TAKE TO THE DEALER TO HAVE IT FIXED THEY TELL ME THEY CAN NOT GET PARTS. THE TRUCK HAS BEEN DOING THIS SINCE I FIRST BOUGHT IT. AT FIRST IT WAS INTERMITTEN BUT NOW THE ABS LIGHT STAYS

My 2018 Ram 2500 6.4l is experiencing intermittent ABS, traction control, electric braking warnings on the dash which affects cruise control once alarm is active. This issue seems to be globally.

First the abs module failed then the abs hydraulic control unit failed. It has been over a year and no part is available.

Consistent warning stating, "Service Anti-Lock Braking System" and "Service Traction Control System" from the vehicle. While this warning is indicated by dinging tones, text displaying in the vehicle information screen, and lights lit on the dashboard, the ABS, Traction Control, and Cruise Control Systems do not function. This is a severe safety risk as if this occurs while driving your cruise control immediately shuts off and if driving in slick conditions you no longer have anti-lock brakes, nor traction control. This is apparently a known issue of Fiat Chrysler on the 2017-2018 model year vehicles where the HCU (Hydraulic Control Unit) needs to be replaced which will remedy this issue. The parts however seem to be in very short supply and not all vehicle mechanics can make the repairs as I am being told you need specific software to reset the system once the HCU has been replaced. This is estimated to cost between $1200-1800 to have repaired. I have reached out to Chrysler Cares and they advised me to take my vehicle to my local dealer for repair and advised there is no warranty, nor recall in place to cover these costs.

ABS/HCU is constantly failing causing my breaking, traction control, and cruise control to fail.

Had to make a hard stop, now ABS light is on, lost cruise control and traction control. Part is on world wide back order, sometime next year, reading many issues with this year abs system.

Vehicle pulled out from parking lot in front of my truck. I had to hit the brakes very hard and they took longer than normal to stop. Luckily I was able to avoid the accident by going into another lane. Immediately after the abs and stability control lights started flashing and a “service abs system” and “service electronic braking system” messages started. They went away shortly after but since then intermittently sound a warning. When this happens cruise control disengages. Took the truck to the dealer on 7/26 and was told it needs a new hcu abs module. The part is backordered until at least February of next year.

ABS light turned on on the dash. Next a warning that the park sense, ABS, four wheel drive, and Cruise were disabled. Had Diagnostics run and found that the vehicle ABS is logging C0020-01 and C0020-16. Case number S2005000004 from STAR showing this to be a known issue. Contacted every dealership within 100 mile range and the needed part of an ABS HCU is unavailable until at least February 2024. Contacted Stellantis Customer care and they will not assist unless the vehicle receives an official diagnostic from a dealership that will cost me at least $150 and they will not assist with replacing the part or even supplying the part so there was no gain from having the diagnostic officially done at a RAM dealership. Well known issue per every dealership and many online forums. No assistance from RAM/Stellantis at all.

ABS pump motor control: apparently this is a major problem according to dodge bulletin boards. The replacement part mopar was shipping was defective so they made a updated part that is nearly impossible to get nobody has any stock. Subsequently everyone is driving around with a Faulty ABS system. This is very DANGEROUS. Some people are stuck because the can’t pass inspection for registration purposes with the fault light on.

Vehicle receives service electronic brake system. HCU and ABS module seem to be the issue. Cannot drive more than 20 mph without message saying service is needed. It is constant up to 80 mph. Vehicle is parked due to safety reasons.

Message comes up to "Service electronic braking system." Code found was C0020-01 (ABS pump motor failure). Couldn't order part due to engineering review. Truck only has 20,400 miles. This part cannot be worn out. Should be a safety recall.

ABS Module and HCU Failure. No ABS or Traction control which could cause the driver to lose control of the vehicle. There have been several complaints filed but no recall issued. The same part (same part numbers)was recalled for 2019 and newer trucks.Service brake and traction control system lights on. Parts on extended back order.

ABS / Traction Control turns on and off intermittently without warning when this happens the cruise control turns off creating sudden loss of speed control

Loss of abs, cruise and traction control randomly, Abs code -C002001 After search seems to be common issue on 18 rams 2500s

At Around 44k miles the ABS and traction control light started coming on along with the warning chime. Brought truck to the dealer for diagnosis and they said it needed a ABS hydraulic control module, P/N 68143491AB. I ordered the part but dealer stated that so many parts are defective that part is back ordered at least 4 months. I have no choice but to drive the truck with defective ABS module.

The antilock /traction control warning light and alarm is going off in my truck. I took it to Woody Folsom Ram Dealership in Douglas,Ga . They informed me that my HCU ( hydraulic control unit) needed replacing .They said they could not even order the part until Feb. 2024. so now if we drive the truck if is less safe especially in inclement weather. This is so dangerous for the Ram company to not have the parts available especially for parts concerning the safety of their customers.

8 month ago my abs and traction control light and warning bazzer came on. i immediately took vehicle to local ram dealership where i bought in it new. they done diagnostic test and told me it needed a new abs hydraulic control unit . i was told that no parts where availiable at this time and it could take 6 to 8 months to get parts. i am still waiting for parts to arive and it would cost about $1400 to fix. this truck only has 25.000 miles on it. also was told it would be ok to drive it but i am not so sure about that since the antilock brake system is not functioning.

Antilock braking system and HCU failed. Causing loss of antilock brakes and cruise control. M multiple warning lamps flash on my dash intermittently. My truck is now unsafe to drive due to lack of proper braking. This issue has been both confirmed by the dealer and an independent mechanic. Part is backorder due to numerous vehicle having this issue> recently the availability of the part has now changed to February of 2024.

ABS module and pump failed at 65k miles. Lost braking performance and stability control. Confirmed by ram dealership. Parts are on nationwide back order.

ABS and Electric Braking System Failure

ABS light comes on frequently and disables the ABS and cruise control. I dings each time and does so frequently when I hit a bumpy road. Ram says the parts are back ordered and none are available. This should be a recall due to the anti skid control not working properly.

2018 RAM 2500 6.7l service abs system and service electronic braking system warnings on dash. Took vehicle to mechanic shop and scan showed code C0020-01. Symptom/Vehicle issuse: C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. Replacing the HCU and ABS Module seems to be the fix. I bought the truck as a hauler for 5th wheel camper and do to abs and traction control failure it can be extremely dangerous to drive.

Driving, hit 40,5xx miles and ABS and traction control light was flickering on and off. Kept getting warnings to service ABS and Electronic Brake System. After 25 miles of on and off flickering and chimes which were extremely distracting, it turned on and stayed on permanently. I do not have ABS, Traction control or cruise control. This is a known issue with the 2017/2018 models, and Mopar does not cover it even though it should be a recall. Thousands of people are having this issue, and dumping thousands into it all for it to just break again in 10/20k miles. The ABS modules are complete junk

Vehicle: 2018 Ram 2500, mileage 35171. Beginning in April 2023 the ABS and Traction control dash lights would intermittently flash while sounding an alarm. The message on the dash states "Service Anti-lock Braking System" and "Service Electronic Braking System." This creates the issue of losing ABS and traction control while disabling cruise control. As time progressed it would become more frequent and would more prominent during extremely humid or rainy weather. First call to dealership was told "We can only diagnose IF the vehicle is demonstrating the issue." At that time I indicated to the service tech that there are numerous national forums with the exact same issue. Truck was brought to dealership for official diagnosis: $179.00 diagnosis fee; $411.70 Labor to remove and replace HCM; $262.00 HCU (Part # 68143491AA); 447.50 labor to remove and replace ABS Module; and $388.00 ABS Module (Part # 68347098AB). Service tech advised me that all parts are on back order and I could possibly be without the truck until mid/end of August. This is an issue the manufacturer should be obligated to correct.

Hello, I have been having issues with my 2018 Ram 2500. The Service Traction Control and ABS lights on the dash have been flashing on and off constantly. Along with no Cruise Control when this happens. This has been going on now for about 3500 miles. I am still driving the vehicle due to being my only work truck. I have been doing some research along with talking to the Ram Service Departments and have noticed that this is a very large safety problem that is highly known about that is not being taken care of. Even the service manager I had spoken with is amazed that this has not been a recall. This should most definitely be a recall and should be taken care of before more people get injured or killed.

I was driving my truck home from Wyoming and my ABS and Traction control lights started to go on the Fritz which caused me to lose cruise control while pulling my camper trailer that weighs 10k pounds with my family in the vehicle.

The ABS and traction control lights are staying on and the truck only has 8,200

57,XXX miles on truck. 11 months out of full warranty. HCU and ABS unit failing at random times during normal driving conditions. Keeps throwing service abs, and service electronic brake controller. On off, on off, on off non stop, constantly the whole time truck is being driven its almost undeliverable. ABS unusable stability control not available traction control not available

My ABS service light keeps intermittently coming on and then off. Sometimes days go by without coming on. The all of sudden it comes on. Brakes feel like they are working but brake pedal seems soft. This is a safety issue. Vehicle is awaiting dealer inspection.

Hydraulic control unit has failed on the ABS system at 50k miles causing breaks to lock up when wet or heavy load also loss of traction control. Tried to get fixed immediately in April 2023 but was told no stock by dealer and still waiting. I feel that the truck is unsafe to drive but I have no options to have it fixed. I had a previous repair done at he dealer with the same issues at 15k miles while under warranty.

On my 18 ram 2500 there’s a problem with the ABS module and controller truck has 49620 miles on it I’ve seen so many others on your website with this problem I can’t see why there’s not a recall from y’all yet because clearly we LOOSE ABS AND A 10000 pound truck that is bought for towing and pulling gos into a full blown slide all over the road then off the road with my camper in tow with or without a trailer behind it makes a VERY DANGEROUS Situation, and don’t know why ram is no fixing the problem

ABS light beeps, service antilock brake system light goes off, swirly lines light goes off.

This is the second time I have had the HCU fail, first time was replaced was at 40653 mile (July 22, 2022) and now again I have the same problem at 46486 miles (Jun 4, 2023), less than 11 months after repair. I use my truck to pull at 12,000 lb. 5th wheel RV so beeping every 3 seconds, no ABS, no cruise control, no traction control is not good.

ABS & Traction Control warning off/on on irregular basis Turns off cruise control each time the warning lights activate

ABS and HCU service problems

I was using my cruze control on the interstate in the rain when I heard dings from my dash and kicked my Cruze control off. It said service electronics breaking system and service abs system. It flashed my abs light and my traction control light. It cause my truck to start sliding and luckily no one was close to me and I was able to gather it up but my brakes did not feel right. From my research this is a very common issue with my truck to the point you can’t get the part to fix it.

ABS system keeps coming on and off saying to repair. Code C0020 ABS pump motor ctrl pulls up on scan reader.

2018 Ram 2500 ABS issue. ABS warning light and traction control lights flashing on and off.

ABS hydraulic control unit failed. less than 25k on vehicle. dash message to service and ABS and traction lights as well. bumps and hard braking seemed to cause this to happen, but originally happened as driving as normal. vehicle was rendered uninspectable by dealership and part was ordered . called chrysler and was told this is a known problem without a recall at this time.

As of 07/10/2023 vehicle Display saying "service electronic braking system" and "service ABS" intermittently. Vehicle is available for inspection. Vehicle has 46000 miles on odometer. upon further research this is a very common problem involving the need to replace the ABS module and HCU to fix the issue. there is a class action lawsuit on this matter. Estimated repair cost is $1700. Failure of these components can cause injury or death. Vehicle is not recommended to be driven with these component failures.

I have a 2018 Ram 2500 I has second abs module failure and dealer still has failed to get my truck fix. the abs failure been failed back in 12/25/2022. with abs failure cruise control is lost also.

The anti-lock braking system will fail intermittently which disengages the cruise control and traction control system as well as cause an audible chime. When this occurs, it may happen once or many times over the course of a few minutes, stop, start again, or stop altogether to reoccur a few days later. The issue appears to be the ABS control/hydraulic control unit issue others report. Loss of anti-lock brakes is a concern in itself; however, trucks in the class of a Ram 2500 are regularly leveraged as tow vehicles. Losing anti-lock brakes and traction control while towing increases risk significantly. In addition, losing cruise control coupled with simultaneous warning lights and chimes creates a significant distraction for the driver which under difficult driving conditions may prove dangerous.

Warning chimes and lights on dash appear stating a problem with antilock brakes and traction control. It appears to be intermittent and I also lose cruise control.

ABS (automatic braking system) audible alarm and visual light comes on constantly. Dodge Ram has changed it twice but it continues to fail. They have said the parts have been on back order for almost a year. Please help me get this safety issue resolved.

My and many other Ram 2500s have a TRACTION CONTROL & ABS unit failures. (HYDRAULIC CONTROL UNIT) Dealerships across the country have no replacement parts and if they do, it cost upwards of $1,000 and in a lot of cases it will fail again. For the safety of our roadways, Ram needs to be put out a recall for this failure.

ABS control Module 68347098AB Electronic stability control unit- abs module 68143491AB Truck only has 78k miles on it and these have failed. after doing research it is a common problem in these trucks but have not been recalled. This is a $1,200 fix and the part is on back order for months due to the issue of it failing.

Ebs light comes on and I lose traction control and cruise control. Happens more often when humid and/or raining . When I use brakes when warning Iight is on brakes lock up -especially in the wet

This is the second time the antilock brake control module has failed and this truck has less than 75k miles on it. The warning lights constantly come on and off and if I needed to brake I am not sure that my antilock brake system would work.

Truck has 67,000 miles and is currently at the dealership for the 3rd time with hydraulic control unit and antilock brake system modules needing to be replaced. Service ABS and service electronic braking system lights constantly blink and alarm is chiming. Dealership says part is on backorder with no ETA.

Abs and traction control

My ABS system has gone out two times since I’ve had the truck. I’m original owner of The 2018. Repaired once under warranty and now at my cost. I feel it’s unusual and unsafe for this to happen in only 80,000 miles

ABS control module and Pump issues cause intermittent braking problems.

Multiple intermittent warnings for "Sevice Anti-Lock Brakes" and "Service Electronic Brake System". Code C0020-01 for General electrical failure/ABS Pump motor control failure. Warnings seem to occur randomly while driving. Sometimes dozens of times within just a few miles driving. When warnings are present, traction control and cruise control are not available. I am unsure that the anti-lock braking feature will work if needed. Vehicle had ~ 40,000 miles when issue began. Spoke with local dealership. They stated they are aware of the issue and that no parts are available to fix the problems. All attempts to find available replacement parts online has shown all parts to be discontinued or back-ordered with no estimated arrival time for new parts.

When I bought the truck in July of 2022 I worked out of state so I went home (Alabama) to pick it up and on my way back to Indiana (where I was working at the time) and the truck shuts off so I took it to the dealership the following Monday and they told me there was nothing wrong with the truck when they diagnosed it which cost me 300 dollars so I drove it back home and took it to another dealership and they said the same thing So I finally got it into a place that would fix it and it was the egr and the radio that had caused it to shut off but the dealership told me they couldn’t get the parts in to fix the other thing so I would have to wait so I’ve waited 4 months and been to 6 different dealerships since then and they’ve told me that the egr is going out once again and my abs braking module is not any good but none of them can seem to fix it they all tell me that it’s going to be in the shop for at least 3 months but I haven’t gotten a call back from them when I leave and they tell me there going to order it

The components failing are the anti-lock hydraulic control unit and electronic anti-lock module. While the brakes work, the safety of the anti-lock system does not provide controlled emergency stopping. The Manufacturer is aware this is a common problem that has not been reliably rectified leaving drivers at risk of injury Warning messages began showing in June 2020 at approximately 29.5k miles. Research revealed this to be a common issue with the 2018 Ram 2500 and 3500 trucks. The local dealer confirmed the issue and noted it as a common problem. The faulty parts were replaced by the dealer under the factory warranty. The warning messages are showing again in June 2023 at approximately 74.5k miles. The local dealer who previously completed the repairs stated this problem has continued to be an issue and must be replaced again.

There is a service electronic brake message along with the service antilock brake, this is an intermittent warning then is a continual lifts on dash. Cruise control shuts down without warning and not sure if any braking components are affected or will have an issue while traveling. I have replaced the recommended components at the dealership and having the same issue in less than 20k miles.

The ABS module and the hydraulic control module have failed twice in 75,000 miles. Not having abs or traction control is a huge safety risk for a truck that is designed to haul heavy loads.

Faulty ABS module causing loss of anti-lock brakes. Results in poor braking and skidding in wet conditions.

My vehicle has intermittent ABS/Traction Control/Service Anti-Lock Brake warnings. Upon trip to the dealership they notified me that I had codes for active wheel speed sensor and a stored Anti-lock Brake Module fault. Upon repair of the Wheel Speed Sensor, I had a reoccurring fault of the same and all ABS/Traction Control/ Service Anti-Lock Brake warnings and the same wheel speed sensor fault. They informed me that they could not order the ABS Pump Module as it was on engineering hold because of an investigation by NHTSA. Please make these people recall the ABS systems on these vehicles as when I look for information it is happening to hundreds if not thousands of trucks. My truck has 125,000 miles on it and has been WELL kept, and Mopar/FCA will not even sell us the parts to make our vehicles safe again. Currently due to the fault I have no cruise control, no four wheel drive, no parking sensors, and NO ABS OR TRACTION CONTROL. Seriously dangerous. Thank you.

Continuously get “ Service Brake System “ and ABS light comes on, Traction Control, and Cruise controls go off. This problem happens constantly every time the truck is driven. Scanner reading shows code “C0020-01” ABS pump motor general electrical failure.

ABS lights flash on the dash, electronic braking system fault, traction control flashing. Intermittent. Research shows replacing HCU will resolve, I will order the part and repair myself but this should be a covered recall since it is a safety concern.

Abs brake pump motor failure. Dealership has replaced with new parts and new parts have failed. Vehicle only has 20,000 miles on it. Not only is there no part’s available but manufacturers tells me I will have to pay the $1700 repairs.

I started my truck on 6/26/2023, and the service electronic braking system light came on, then went off. It has been intermittently coming on since then. When the light is on, I lose ABS, traction control, and cruise control. I had the ABS system repaired under warranty, then again out of pocket in August of 2022 at Ron Carter League City for the same issue. This is a safety concern due to the loss of safety control measures, and needs to be recalled

The ABS Hydraulic Pump seems to have failed and perhaps took out the ABS control module. Nothing catastrophic happened on road. Simply lost ABS, Traction Control, and Cruise control….and soon $1,500 The hydraulic pump was listed in the Ram Dealer parts system as “Under Engineering Review” for at least a couple months and i can’t find out what that was about, the resolution, etc…. Wanted to log here in case it becomes a regular occurrence on these vehicles.

I continuously receive “service electronic brake system” and “service ABS” warnings. Every time this happens, the service lights on my dash come on and the trucks “dings” to notify me (very annoying when this happens multiple times in the same trip). These go off and come back on multiple times per driving session. Timing varies, sometimes on and off in seconds, sometimes the entire trip. This started as a one time warning and went away, now it happens every time I am in the truck. I have researched this a little and found that the brake control has a known issue, however no recall has been made to correct the issue. Thanks!

Hard braking for a deer the abs ,traction light came on lost abs and lowbeam lights wile rainy and lost auto wipers

For a few weeks now, my truck has slowly begun to light up and ding, saying “service ABS” but going away. It started to ding continuously and then lit up saying service electronic braking system and ABS. Now I feel as if the only vehicle I own is not safe to drive. I have read the numerous complaints online stating they had the same issue and feel I got sold a lemon with known issues. I cannot knowingly transport my family in a vehicle that isn’t safe. I am a completely disabled veteran and bought this truck with the intention of it being a diesel engine that would last me. Unsure how to proceed.

THE SERVICE ELECTRONICS BRAKE SYSTEM AND TRACKION CONTROLL ERRORS POP ON AND OFF. SOMETIME THEY STAY ON FOR AWHILE. SAFETY CONCERNED I HAVE NO ABS DURRING THESE TIMES THE ERROR IS ON.

I began receiving the Service Electronic Braking System and ABS warnings. In turn, those warnings disable cruise control and traction control. I tow heavy with the pickup and need the systems to work. My understanding is that this is a common problem with this model year. In turn I will not repair this issue on my dime and should be addressed by Ram due to faulty engineering. Either the system will work or it will cause a problem on the road.

Electronic brake system light keeps Coming on these vehicles along with the tractions control light which is a known problem.

Consistent and predictive Failure of Anti-lock brake control module (68143491-AA /68143491-AB) in 2018 Ram 2500/3500 Trucks. Nationwide shortage of OEM Replacement Parts leading dealers to hoard exclusively for customers for whom repairs are to be made. Extremely difficult to find a dealer willing to sell brake control module, if they have one in stock, to anyone. Instead, dealers recognize there is up to a 6 month waiting period for restocking and therefore taking advantage of those who chose to utilize independent mechanics. Dodge/Ram is acutely aware of shortage, as well as failure of part and has chosen to not warranty or conduct a voluntary recall. Every Ram mechanic and parts office I spoke with acknowledge EVERY 2018 Ram 2500/3500 will fail. The subject vehicle had under 31,000 miles. During failure, the vehicle loses its' anti-lock functions, traction control, defeats cruise control, dash continually lights up with error message 'SERVICE ELECTRONIC BRAKING SYSTEM' then 'SERVICE ANTILOCK BRAKE SYSTEM' while simultaneously and constantly generating an audible warning over and over again during the operation of the vehicle. Price gouging for part, if you can find a dealer that 1) has the part in stock, and 2) willing to sell the part can run between $180.26 - $525.02 (MSRP $262.00). Part is in use for year models 2012-2018. I personally paid $525.02 (and grateful a dealer sold the part to me over the objections of the parts manager), drove 4 hours to obtain, plus install.

6 months ago, the ABS brakes and stability control warning lights started to randomly light up on the dashboard. Sometimes I would not see a repeat of this for a week or more. The warning lights started to appear more frequently, and now are on all the time. When on, the cruise control does not operate. I took it to a Ram dealer near me, and the service department confirmed it is a defective ABS pump, known as the HCU module. They then informed me that Chrysler has no inventory of this part! I asked how long to get one, and was told some people have been waiting for over a year! The part, # 68143491AB, appears to be readily available online from a multitude of vendors. My truck has only 34,000 miles on it, and no ABS, no Stability control, and no cruise control is a safety issue! Please HELP!

The HCU and ABS modules are defetive. After calling several RAM dealerships, parts may not be available until August and they will not have enough parts for everyone.I do not know if it is safe to drive. WILL THERE BE A RECALL?

Subject: Investigation Request: ABS Fault Code C0020 in 2018 Ram Trucks Dear NHTSA Team, I write to bring your attention to a critical safety issue affecting numerous 2018 Ram trucks. The problem revolves around the faulty ABS HCU, This fault leads to intermittent or complete loss of ABS functionality, posing significant risks to the safety of vehicle occupants and others on the road.The ABS system plays a crucial role in preventing wheel lock-up and maintaining steering control during braking. However, the faulty ABS unit compromises the effectiveness of the ABS system, particularly in emergency situations and adverse driving conditions. The inability to maintain stable braking performance raises the potential for accidents and reduces the overall safety of the affected vehicles.In light of these safety concerns, I kindly request the NHTSA to launch a thorough investigation into the ABS, HCU/Module in 2018 Ram trucks. The investigation should aim to identify the underlying cause of this issue, assess its prevalence, and evaluate the severity of its impact on vehicle safety.Furthermore, I urge the NHTSA to engage in collaboration with Ram Trucks, the vehicle manufacturer, to ensure that affected owners receive timely notifications about the issue. It is essential to establish a process for providing necessary repairs or replacements to affected vehicles at no cost to the owners. This proactive approach will help mitigate the safety risks associated with the ABS units.As an organization committed to ensuring road safety, the NHTSA plays a vital role in addressing automotive issues that pose potential risks to drivers and passengers. By investigating and resolving the faulty ABS units in 2018 Ram trucks, the NHTSA can uphold its mission of safeguarding the well-being of vehicle owners and promoting overall road safety. Thank you for your attention to this matter. I eagerly await your response, detailing the actions taken by the NHTSA to address this safety concern.

There is a fault with the ABS sensors. Everyone I know with same year make and model has the same issue.

Service ABS System keeps coming on when I hit the brakes.

ABS light on when braking had to apply full force , truck would not stop for about 20 feet was moving slowly so no accident.

I have 39,000 miles and my ABS and Traction control lights come on which lead me to do a scan of the vehicle. Come to find out that my ABD module is bad. Tipm needs to be replaced. I looked up if there is a recall and seems to be a lot of people having the same issues.

I've been dealing with the ABS light going on & off with alarm constantly chiming for almost 2 years now. The anti lock breaking is compromised as is my cruise control. I can no longer operate the vehicle safely and I've had to park my truck permanently, which has created many economic and logistical issues for me and my family. I work 60+ a week to support a 2 and 4 year old child. The abs modulator and hydraulic unit need to be replaced according to the dealership (Ferman Dodge, Holiday, Florida) and (2) other non-dealer mechanics (Hilton Automotive, Ocala and Tuffy Spring Hill) have stated the same when I sought a 2nd and 3rd opinion. I don't understand why there's not a recall? Please, advise to the steps the NHTSA is taking to resolve this ongoing issue. I'm still waiting on the part/ parts to become available and I've been waiting for over a year now. I've reached out to every possible avenue that I know of to source the parts, to include aftermarket non-Mopar parts, and I'm being told they are still on back order. I can not afford to sell my truck in it's current state, as its currently "unrepairable" and that has severely diminished its value. I should not have to absorb that loss because of Dodge's negligence. Dodge needs to be held accountable for this, I purchased a very expensive truck in search or reliability and safety and I have received neither of those things. Please advise, my family cant afford to have a $50,000 lawn ornament any longer. Thank you!!! -[XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

intermittent abs system failure, turning off cruise control and and traction control. system failure began at about 11,000 miles and 3.5 years of ownership

ABS Hydraulic Control Unit C0020-01 ABS Pump Motor Control Has been in for repair once and diagnositc 2nd time. Awaiting parts. Anti-Lock Brake System Warning Light, Traction Control Warning Light, Service Electronic Brake System Message - Continuous Lit and Intermittent Chime

2018 Dodge Ram 2500 with Cummins turbo diesel. When driving, the dash warning light for the ABS and the Traction Control System intermittently come in and spontaneously reset. If the cruise control is on and set, it turns off without driver input. Dodge dealer states that the hydraulic control unit needs to be replaced, but they have been on back order for over a year.

ABS brake sensor and traction control sensor issues. Sensor continues to trip and then go away. I have no idea if the systems are actually working properly or not it may just be a wire, wire harness or the module. When is does trip it ony does so for a short peroid. I drove 20miles yesterday and it tripped and seem to reset it self 30+ times in that short drive. The constant bonging was distracting. Also this keeps the cruise control from working. This issues seems to come and go.

2018 Ram Display Brake Error Service Electronic Braking System and Service Antilock Braking System Error Code C0020-01

Braking power was diminished. ABS and Traction Control lights illuminated on dashboard and did not go out.

Ram 2500 began having problems in late-2021. The truck's warning lights indicated the ABS module, HCU module and cruise control failed.

My truck has 32850 miles on it. This is the third time my ABS and EBC lights have begun flashing. My HPU and brake control module must be replaced again. Ram needs to be sued.

Abs and traction control indicator lamps have an intermittent flash and alarm that alert at random times. This is dangerous as this not only disables the cruise control but the traction control is then disabled as well as the abs system causing brakes to lock up. Mopar and ram refuse to fix the issue and it costs consumers $1200 for parts and labor that may or not fix the issue. This is reported in many forum pages as well with all having the same complaints and stuck with the repair or not due to unreasonable cost associated with a possible fix. This should be an immediate recall as it is a safety concern even more so than an airbag issue. I cannot fathom a government agency responsible for safety to not mandate this as a recall.

2018 RAM 2500 ABS module failure in 9/22. Dealer diagnosed & said part was on back order until 12/22. I have called the dealership multiple times checking on availability of the replacement part & each time I am told a different ship date with the current ship date a year out from the start of the problem. RAM seems to be unconcerned their product is endangering their customers with ABS failures which, unless I'm mistaken is a required feature on vehicles. The warning lights & "chimes" are constantly going off which is a distraction for the safe operation of this motor vehicle. The fact this is a know issue & the "fix" in my case is a year out is unacceptable. This component(s) have already been replaced by a recall & now failed is not acceptable. Through online searches, this is a known problem that has drug out too long & posing a risk to the drivers & passengers of these trucks & the traveling public that shares the road with these trucks.

Hydraulic control unit. Been waiting on part for over a year. This unit controls abs, cruise control and traction control

As of 6/6/2023 The ABS module is indicating a fault and then the fault goes away repeating this randomly while driving. This is the second time this issues has occurred. Due to the high volume of ABS issues with this model, my dealer has indicated they can not get the ABS unit until Mid August of 2023 and can not get me into the service to confirm this is the issue until July 19, 2023.

This is the second time I am having an issue with my abs on the 2018 ram 2500. At about 34-36k miles the abs light started coming on and off randomly. Brought it in and the abs pump was changed. Now at 58k miles it is acting up again and they want to charge $1,200 to replace it. I did research and found this is a common issue with this year model.

2018 Dodge ram 2500 diesel ABS warning lights comes on with constant warning dinging sound. Had vehicle scanned he said ABS brake module was bad. On 9/10/21 this part was replaced with the same issues by Breeden Dodge Fort Smith, AR at a cost to me of $650.60.

The ABS and Traction Control light intermittently displaying a fault. Cruise is not available when the fault occurs. The Ram forums have countless number of reports with regards to ABS issue with low mileage trucks. 2018 RAM 2500 truck only has 16.7k miles and I purchased it new. I contacted Dodge and the ABS module and HCU module are not available until August. The dealer wants to charge $200 to look into it. I verified the vehicle speed sensors, wiring and connectors have no physical damage. Yesterday we took the truck out for about 20 miles and the light stayed off the whole time. Today I took it out and within 1 mile the lights started flashing. Connected NT301 CAN OBDII & EOBD code reader and no codes are displayed. On line forums indicating dealer repairs are temporary and have cost $1200-$1500 for repair. This needs to be addressed by the manufacture. On wet roads and on snow and ice this would be an issue if emergency stop is attempted locking the brakes.

For the second time, my ABS hydraulic control unit has failed.

I am getting intermittent errors in my ABS and traction control systems. Code C0020-01 stating ABS pump motor general electrical failure.

The ABS and HCU modules have failed multiple times now. This leads to a loss of braking power and notifications of service braking system, a loss of traction control, and poor braking performance. The dealership is currently replacing the parts for the second time. The vehicle only has 37,000 miles and the ABS module has only worked for half of that. When the ABS module begins to fail, braking becomes more difficult, cruise control stops working, and the traction control system does not work. This leads to dangerous driving conditions in rain and on wet roads and I will not allow my family to ride with me if the system begins alerting due to the risks of crashing.

For about 8 months, our 2018 Dodge Ram 2500 has had interment ABS and HCU warning lights and the notification to "Service electronic braking system" followed by "Service antilock brake system". This may occur for a period of hours or seconds and disables our trucks ABS, traction control, cruise control and other systems. When checked, the truck has no stored fault codes. When this first occurred, I went to the dealer where the truck was purchased and inquired about replacement ABS and HCU modules and was informed that none were available. After subsequent visits and internet research, I found TSB#C0020-01, "ABS Pump Motor", that directs replacement of the ABS/HCU modules, and directs that the replacement parts will be provided by a "STAR system". We have had three incidents that we narrowly avoided accidents, two due to the intermittent ABS failure and one due to sudden loss of traction control while pulling our trailer. It has also noted that a Class Action Lawsuit has resulted from this same issue.

Service ABS system message turns on and off continuously while driving. When the warning is active ABS is disabled. Also when the warning activates it will disable cruise control suddenly. It continues to turn on and off. Dealership diagnosed it as ABS control module. They state there are no parts to replace it with at this point in time and no ETA on when a part will be manufactured. They also stated they believe it should be a recall item as 2019-2022 models had similar issues and was recall issue. Non working ABS and sudden cut off of cruise control is a safety concern. Significant research on my part shows this is a very common issue with these vehicles. This happens without fail every time the vehicle is driven.

Hard braked to stop from hitting object in road, abs and tcs light came on. Abs module and hcu need to be replaced, but hcu is on backorder and currently people are reporting 12 months plus to obtain it, and I need to meet fmcsa requirements with no part availability.

ABS and Traction control light on. One of thousands of complaints I see regarding the same issue all over the forums online. It all seems to be 2017-2018 models from what I gather it’s the ABS module or ABS Hydraulic control unit. Not only is it annoying to hve the constant beeping on a truck with only 39k miles, it’s also highly dangerous to have to drive around with faulty brakes!!!! Please look into this I know it one of thousands of complaints regarding this same exact issue.

ABS & Traction light flickers and stays on. Brakes have pulsed. This is very dangerous for my family and myself. Ram wants to charge me $$ for a manufacturing defect that they are all to aware of. This not fare.

HCU / ABS module issues. Truck while driving has no cruise control my lights stay illuminated all the time, truck only has 57,000 miles and already repaired all 4 abs wheel speed censors, spent countless hours visibly checking all wires and fuses make sure no defects there. This could be a very dangerous and life threatening situation and I would think it's only right for Dodge Ram to recall the 2017-2018 for this ABS issue.

ABS ESC constantly flashes and chimes non stop…. Failed control to wheels in wet weather conditions/ no cruise control/ 4x4

ABS system, electronic braking lights keep coming on and off. Truck has 38k miles, and computer is saying bad pump and module.

Truck has disabled ABS braking due to failure. Shows no code on ABS module. Will not let cruise or ABS work and Constantly beeping at driver.

ABS Hydraulic control unit failure. ABS and traction control lights on resulting in no ABS, traction control and cruise control. This is a common issue. The part number 68143491AA has been superceded by 68143491AB of which none are available with no ETA. This is unsafe and unacceptable. Also an expensive part and replacement. This needs to be resolved and reimbursed for the consumer, it's a $60K truck and my retirement vehicle.

ABS system does not work. Issue with the ABS pump motor control. Dealer stated it’s a know issue. This is the second time in a year I have taken to the dealer. Parts not available till August I was told and 6 other people are in front of me to get it replaced. Issue also affects traction control.

I had my my ABS module go bad at at 2 years and 9 months the ABS module went bad again been not on working conditions Since December of 2022. Went to the dealer 3 times part is still back order until August 2023. I am not the only person having this issue there is many out there. This part needs to be recall from Mopar.

The Anti-Lock Brake control module along with the Hydraulic control unit is failing. At any rate of speed, the traction control light and the ABS light comes on and off repeatedly. When this happens, the cruise control disengages which has cause the truck to slow down rapidly in heavy traffic causing other drivers to almost rear end my pregnant wife, 3 year old son and I. I had my local ram dealer pull the Diagnostic Trouble Codes and confirmed that the parts stated above, were in fact failing. The messages that pop up on the instrument cluster are “Service Anti-Lock Brake system” and “Service Electronic Brake System”. I can not have this component inspected as it is a daily driver and is the only vehicle we have currently.

The ABS, traction control, cruise control and 4x4 no longer function. It started intermittently and now is constant. The vehicle is available for inspection. After a hard stop the abs won’t engage and I lost traction of the truck. There are two warning lamps that are on at all times (abs and traction control). It has been ongoing for almost 1 year and 10,000 miles or so.

Since I bought truck with 9k miles abs traction control light has came on, told it was hydraulic control module. Part is on back order and almost impossible to get. Was driving 70 mph on freeway on cruise control all of a sudden warning service anti lock breaking system popped up and cruise control kicked off and brakes locked up. Luckily I was able to control the slide if I was pulling my fifth wheel I might not be so lucky. It pops on and off all the time I have tried to locate this part for awhile now and know this is a common problem with no recall

My 2018 Ram 2500 started getting an intermittent "Service Electronic Brake System" console message and light followed by a "Service ABS System" warning. I researched the symptoms online and saw that the NHTSA is currently conducting an investigation into this issue with similar vehicles, and Ram is facing two class-action lawsuits about it. Further research says that this could cause a serious braking issue.

At 35,000 miles on vehicle the ABS and service braking system started alarming and illuminating, stopped for a couple of days then started again, this is a daily driver vehicle. (ABS Module/HCU ?). The alarm is becoming for frequent.

ABS service light continues to ding. Part replaced 12/2019 @ 6,000 miles. Issue again 5/2023 @ 24,500 miles. Dealership unable to order part states it is defective for 2018 dodge ram 2500 truck. This causes abs failure.

Driving down the highway with the cruise control set and all of a sudden the cruise control stops working and my dash is dinging with service ABS system and service Electronic Brake System. The truck had 78,500 miles when this first happened. Now it does it intermittently while driving down the road. I notice there’s no recalls and it sound like a large problem. Haven’t taken it to a dealer yet.

ABS Control Module defective at 40,000 miles. OBD scanner confirmed issue. Warning lights and dinger sporadically on and off.

Getting Code C0020. The ABS light and traction control light go on and off while driving down road. This also disables the cruise control. Seems like alot of people are having this issue with there Rams. Seems like a safety issue with the brakes because its intermittent.

At 36,000 miles have been told I need to replace ABS pump control general electrical failure. Also replace ABS module. Parts are not available and are on backorder. I pull a 25 foot camper and this issue is causing concern with vehicle stopping. Apparently is a big problem as parts are not available and dealers that have part will not release parts so my truck can be fixed.

ABS light come on intermitting, and dealership said it needs a new ABS module, but they cannot get the part because it is under review, so I cannot even get the part.

I am having an intermittent service ABS warning light. I took the vehicle in for service and they advised that the ABS HCU needs to be replaced. Unfortunately, they said that the part was back ordered till September. Which means my vehicle has an annoying "dinging" as the alert to have my ABS serviced comes on and off, regularly disengages my cruise control, and at times I am without ABS and traction control.

Abs, traction control light comes on for service. Dealer diagnosed as faulty HCU antilock brake systems unit

About every 10 to 15 seconds an alarm sounds and warning sign blinks on dash with message to service anti-braking system and traction control. If cruise control was engaged it disengages and sometimes will not reset until engine is turned off and restarted. Vehicle seems to have braking issues, especially on wet pavement. Brake pads have been checked and are ok. Vehicle odometer has 34102 miles on it. .

Abs / traction lights come on and off intermittently for 2 years now since about 27k miles. It now stays on most of the time. While on, i have no cruise control. A Stare Farm approved repair facilty, Don Shetler Chevy, checked the codes when the lights came on more permanently in October 2022. They state it is the HCU that needs to be replaced. Now out of warranty.

ABS LIGHT AND TRACK CONTROL IS ON AND THE TRUCK IS NOT GETTING TRACTION TO THE GROUND AND MY CRUISE CONTROL IS NOT WORKING WITH THE LIGHT ON.

Brake HCU unit and ABS faulty, cruise control inoperable. Dealer has inspected and reported HCU unit defect and very expensive repair.

This vehicle has had the hydraulic control unit (HCU) replaced once, and the power steering pump replaced twice, with another issue pending resolution. The vehicle has 74,323 miles, under one owner. The symptoms are that the service ABS and traction control system lights and warning indicators will randomly activate, normally after a rough patch of road. The cruise control will not function, nor will the ABS system while this occurs. The dealerships have no replacements, and no estimates of repair.

ABS module system has been replaced twice .. needs to be replaced again per Dodge tech. No parts available. Unsafe to drive vehicle with no power brakes This is not unique to my truck. various individuals having same problem with same model Electrical Instrument cluster with display has been replaced and currently working.

Following a Uconnect update in March 2023 the vehicle exhibited the following errors: rear parking sensors failed, ABS brake failure, cruise control failure. ABS module was replaced 5/5/23 at cost to me of $529.86 by RAM dealer. Per dealer, ABS system will not function as ABS motor (HCU) must also be replaced and is not available pending "engineering review" in late August. Vehicle is like new with 23,000 miles on it. The vehicle is no longer operating as designed by Dodge RAM causing risk to me and others. This is a known issue to the manufacturer and they have failed to issue a recall and correct the problem on this vehicle.

On my way to work one day the check engine light,ABS light and traction control light came on and I thought something under the hood had came loose thought nothing about it and went into work when I came back out and got into the truck the lights where gone no big deal just sorta let it go and since I work out of state this is the truck I drive when I go back to my home state so I drove it 4 hours one way and never had a problem and then on my way back to my work state the truck shut off and wouldn’t start back up for about 45 minutes or so but when it did it had a red lightning bolt,ABS,traction control and check engine light on so I called the dealership and asked them to check on it but by the time they got it in the shop the lights had went back off and they told me that nothing was wrong with it so I went to pick it up the next day but as soon as I got 1/2 a mile down the road it started the same thing brakes going in and out truck shutting off so they paid for it to be towed back and figured out that the egr and the abs brake module was going out and tried to make me pay for everything out of pocket because it had just went out of warranty with ram but it had the extended warranty and keep in mind this truck has 30k miles on it but anyways they replaced the egr but have yet to replace the abs braking module

ABS light turning On & Off randomly causing my traction control to turn off. I’ve read on other ram forms that it caused people to get into accidents or loose complete control of their vehicle. It’s getting out of hand.

2018 Ram 2500 with 50,056 miles on it and the ABS and Traction control light is on again with Code C0020. The first time this happened was July 2020 at 22,300 miles and the dealer replaced the ABS pump motor. It happened again May 2022 at 41,770 miles and the dealer replaced the ABS pump again. Once again the check engine light is on and the pump needs to be replaced again for the third time at 49,900 miles.

The ABS Anti-Lock Sensors keep failing on this vehicle.

Service Electronic Braking System and ABS light is on. I was going 75mph on a highway here in Texas I had 57,487 miles at the time on my 2018 Ram 2500 6.4-liter tradesman crew cab hemi truck. cruise control was on then the light popped up kicking it out of cruise control locking up my back tire for 2 seconds. I called the dealership to see if there was a recall on it they said no. I took it to an aftermarket service center here in Texas and he said the HUC and the ABS module should be replaced at the same time. One of the parts are on backorder its costing me 1,357.98 to replace this. I was doing some research online I notice I wasn't the only one with this issue.

ABS control valve has failed twice was replaced on 11/01/2021 at 67429 miles. On 5/09/2023 truck was put in shop with same problem. Dealer now wants to replace the ABS control valve and the controller

The ABS system failed on my truck while under warranty (around 12,000 miles). I took it to my closest Ram dealer and they “fixed” it by replacing the hydraulic pump associated with the ABS. Everything was fine until about 3 months ago when it failed again. I took it to my local dealer about it and they told me the same part had failed and they would fix it under hood will since it had been with in 3 years. However, after waiting 3 months for a back ordered part to come in, turns out the ABS module failed and it should have been replaced the first time, but since it was not, I am now in the hook for it. Now I am stuck with a 2018 Ram which the ABS has now failed twice within 60,000 miles. This isn’t an isolated incident talking to other Ram owners and judging by the in ability to get replacement parts and needs to be addressed. Thank you.

Driving and abs and traction light error light comes on for about 10 sec and goes off. It did this about 6 times yesterday while driving home. Seeing that hcu module or abs module may be shorting and causing the error to come on. I am seeing online many instances where this is occurring to ram truck owners on 2017 and 2018. I just bought the truck used in April. I don’t know what I should do on this. With less than 50000 miles it seems very bad these units have issues. If there will be a recall and I fix it to make sure I am safe before a recall is done can I get my money back? The contact stated that the parts needed are on back order.

While applying the breaks the vehicle will deactivate ABS and force the vehicle to slide without control. ABS will turn off and on without warning. While using cruse control abs will deactivate and cause cruse control to stop working, causing the vehicle to slow unexpectedly. This has happed while towing a goose neck trailer causing additional pressure on vehicle when sudden loss of cruise control and abs.

Just threw an abs/traction control code "abs pump motor control general electrical failure". I have already replaced my hydraulic control unit in June of last year. So less than a year later the problem happens again. I called for a warranty replacement of the part and was told there has been a stop on the part and will not be available until September 2023. My safety and others safety are at risk due to the heavy loads I haul on a daily basis in the south Florida wet weather.

Vehicle has 62953 miles. Ram service dept says the vehicle needs new engine,pcm,hydro boost assembly, hydraulic control unit, shifter assembly. They repaired the drag link in 2019. This did not solve issue. The tires were being worn rapidly. Ram said they would replace the drag link. Vehicle is drivable but not safe.

The HCU and ABS modules are defetive. After calling several RAM dealerships, parts may not be available until August and they will not have enough parts for everyone. When the service light activates, the cruse control dangerously disengages. Annoyingly, the warning may ding 6 or 7 times and I lose the digital speedometer. I will not be able to register my vehicle as the inspection will fail. I do not know if it is safe to drive. I pull a 5th wheel approximately 6 times per year.

Service Electronic Brake System warning light cycling on and off. ABS, Traction Control, and Cruise Control inoperable.

The ABS, Service Electronic Brakes, and traction control warning alert constantly goes on and off while driving, deactivating cruise control as well. It does it all speeds, in all gears, including on the highway, at 70, in traffic. This is especially problematic in the rain, as I don't know if the ABS will work or not. The alert goes on, resets and goes off, then goes on, then resets, constantly. Sometimes for the duration of the trip, sometimes once or twice. This has been happening since September 2022, for eight months now. The anti-lock brakes or electronic brake system MAY NOT WORK; The problem has been confirmed by an independent service center; The vehicle has not been inspected outside the independent service center; No warning lamps or other symptoms prior to this failure.

The ABS and traction control light is flashing on and off when driving, even though it's a 2018 it only has 7000 miles on it this is a well known problem and is a safety issue. RAM TRUCKS should be taking care of this issue liked they did with the 2019- 2022 modle years trucks I'm also aware of class action law suits for this same problem so that tells me there are many of the same model year trucks having this problem.

ABS light goes on and off. ABS/BRAKE warning with Service Electronic Braking System alert, throws code C0020-01. Sometimes I can drive an hour with no issue then other times it the error will occur many times, on and off the whole drive. Cruise control seems to stop as well. With ABS not failing at random times it's impossible to know if breaking it will be safe when needed. This issue has occurred multiple times (repeatable) and continues as of this report.

INTERMITTENT FAILURE OF ABS/HCU RESULTING IN NO ABS, CRUISE CONTROL, OR TRACTION CONTROL. UNABLE TO FIND THE PART IN QUESTION, DEALERS WANTING NEARLY $2000 FOR REPAIR ON UNACCEPTABLE TIMELINE. UNABLE TO HAUL SIGNIFICANT LOADS WITH TRUCK (I.E. CAMPER OR EQUIPMENT/TRAILERS). DOING RESEARCH I FOUND THAT THIS IS A VERY COMMON PROBLEM WITH THIS TRUCK AND NO RECALL WAS EVER ISSUED. HCU PARTS ARE NOW RESTRICTED AND EXTREMELY EXPENSIVE IF ONE DOES MANAGE TO FIND ONE. CLASS ACTION LAWSUITS INITIATED AGAINST CHRYSLER IN CALIFORNIA. THIS ISSUE HAS BEEN KNOWN ABOUT FOR YEARS NOW AND SHOULD BE MADE KNOWN TO ANYONE THINKING OF BUYING A RAM. I LOVE THE TRUCK BUT IT IS UNSAFE AND INCREDIBLY DIFFICULT TO REPAIR AT THIS TIME CAUSING SIGNIFICANT HEADACHES FOR MY FAMILY.

-Dash warning lights and audible warning intermittently and repeatedly flashing "Service Anti-Lock Braking System" and along with warning "Service Electronic Braking System". Yes it is available for inspection. -Intermittent failure of the Anti-Lock and Electronic Braking System due to faulty OEM parts is a very serious risk in the event of heavy braking to preventing an accident. Mine and my families lives are at a great risk because of this! -No, the vehicle has not been to a dealer or service shop yet. A quick Google search of this issue shows it is now a very big common problem showing up among thousands of Chrysler/Dodge/Ram owners reporting the issue. I am very concerned about driving the vehicle now because of this problem from reading/hearing some other peoples stories of this common issue happening to their vehicle(s). -No inspections has been done to the vehicle/components as of yet. -No warning lights or issues before whatsoever until Friday May 5, 2023. That is when the dash warning lights starting displaying the issue.

ABS lights flashing on dash, intermittent at times, sometimes all the time. Deactivates cruise and traction control. Dangerous when hauling loads. Sudden loss of cruise almost caused an accident.

My ABS (Anti-Locking Braking System) module on my brakes has failed for the second time with only 26,900 miles on the truck. The dealer replaced the ABS Module and pump in 2020 and just inspected it on May 3, 2023. I was told i will have to drive it as is until it is possibly fixed in August 2023, when part might be available with no guarantee on date.

ABS service light comes on intermittantly disabling tracktion control systems, cruise control, and other systems. Taken to dealership and told not a recall item but it known defecton make/model. Told cannot order parts until August and repair not available until potentially september.

Abs module and hcu failed. Unable to have abs. Ram does not have the pump and is redesigning it and won’t be available until aug 2023. I am driving without abs until then. The hcu pump was replaced less than 2 years ago.

The ABS module and HCU pump failure resulting in intermittent brake failure at highway speed.

I purchased my 2018 Ram 2500 mega cab from Grieco Ford in Delray Beach 4 days ago. As I was driving home, the ABS service, electric braking system and anti lock braking service lights came on. Took it to New Smyrna Beach Jeep Dodge Ram, they plugged it in and said the HCU needed replaced and was it n back order until September. I don’t know what to do.

ABS brakes and skid control is constantly alarming. Replaced ABS module and HCU module in 2021. Started malfunctioning again in early 2022. Have been waiting since then until now and have yet to have ABS system repaired. Was told by RAM that it would be at least end of June 2023 before repair is available.

Received Code: C0020

ABS & Traction control lights turns off & on. Thus deactivating & activating traction control.

I just purchased a 2018 Dodge Ram Crew Cab from Crown Dodge in Ventura Ca. Within 5000 miles of purchase the ABS has failed and my breaks locked up on the freeway! The truck was taken into the dealership and the service department told me that the part was backordered till mid August and to do ahead and drive it the next 3 1/2 months and assured me it was safe. They sent me home with the truck and said it was totally safe to drive but just don’t break hard or fast?! I left with the alarm beeping continuously and drove home. I am supposed to live without a truck for 4 months? This truck was purchased for towing my commercial fishing vessel daily to and from the harbor being used in conjunction with my limited entry fishing permits ie: crab, sea urchin, sea cucumber, lobster and deeper nearshore rockfish. Without the truck I can not launch the commercial boat that weighs approximately 8000 lbs. Dodge should be held to a higher standard for their trucks! Please HELP!

Intermittent ABS/ HCU light coming on again. Equipment once replace around 20k. Possibly cause of inability to properly stop cause crash. On Oct 2022.

The service ABS System light cycles on and off continuously going down the road. Upon calling the dealer it is a known issue and parts have been on nationawide back order for months with no resolution in sight until “at least August”. In the meantime consumers cannot use cruise control nor will the electronic braking system work for a pull behind trailer. Not having the ABS function properly is dangerous and Ram knows this is an issue but cannot keep up with the high demand associated with this issue.

Intermittent ABS, EBS and traction control issues causing spurious warnings and loss of cruse control. The alerts are distracting to the driver, loss of ebs/abs represents safety issues while traveling, as does the loss of traction control and cruse control. Dealer has diagnosed the issue to the respective abs/ebs controllers but reports no parts in inventory and no due date for when they will be available. Formally request NHTSA force a recall to require the mfg to correct the issue expeditiously.

HCU and ABS Module stopped working. My safety along with other people’s safety is put at risk because if the braking system is not working properly, especially in slippery or wet conditions, then I won’t be able to stop when needed, which can lead to a deadly crash. Yes, the problem was confirmed by the dealership that the hcu and abs control module will need to be replaced. However, the parts are on back order and do not know when they will be in stock, which is a terrible problem to have when it comes to somebody’s brakes. The vehicle has not been inspected by anyone since the light came on, except for the dealership diagnosis. The abs light and traction control light pings intermittently. The cruise control stops working when the light pings which could also lead to a crash. Customers should not have to pay for the $1800 repair bill for a Chrysler faulty part.

The ABS control module failed which results in the ABS system not working. I took the truck in for repair in June of 2022 and had the ABS Module and the ABS hydraulic pump replaced. Now 10 months later, I find that the truck is experiencing similar issues. If you have to push on the brake pedal too hard to avoid an accident, the ABS system shuts down and warning lights come on in the dash. RAM dealers will not warranty the labor to replace the parts and now you cannot even get the parts as they are on backorder. So we have a truck with no ABS system working and cannot even get parts to repair it. And we have to pay for the repair a second time after 10 months. This is unacceptable as we use this truck to pull a boat and camper and now we feel unsafe without a working ABS system.

There has not been an accident. Hopefully it won't come to that! This needs to be addressed

abs not working for a year now. dodge has no parts to fix issue not safe to drive and should be a safety re-call on hydraulic control unit.

The vehicle experiences intermittent fault displays for "electronic brake service" and "ABS Service". This causes the vehicle to suddenly come out of cruise control and slow dramatically. This causes the vehicles ABS safety function to be inoperative reducing the overall braking capability and increasing the safe stopping distance This causes traction and stability controls to be disabled further degrading the built in safety features This was diagnosed several months ago by the dealership as an ABS hydraulic pump problem with no parts availability. The lack of parts has been an issue for months and has rendered my vehicle inoperative. The dealer said this was a common problem and that they had multiple Ram trucks with the same problem. I also checked online and found multiple reports of the same issue across the brand and across the country. This is a significant and costly repair >$800 for a part which is clearly underdesigned for the applicaiton with poor or little reliability.

1. Anti-Lock Brake System Hydraulic Control Unit 2. Possible safety issue with no ABS available 3. Yes evidently the new part needed in "under engineering review". 4. Took truck to mechanic and confirmed the HCU unit 5. yes have warning messages that WILL NOT STOP CHIMING; Service Electronic Braking system; Service Anti-lock Brake System

The ABS light is on, states it needs to be fixed, we were told by our mechanic that this is a known issue. HCU unit fail and throws service ABS light. Cruise control does not work due to this issue. This started last November and are waiting for parts for the repairs. The truck only had around 74,000 miles when this started. Our repairs are going to be over $1200 to fix. This is crazy, Ram should be recalling these trucks and paying for the repairs.

Faulty abs control module and hydraulic control unit

ABS and Traction control warning lights and chime are constantly on-off, on- off. Took vehicle to dealer, diagnosed as brake module. The module was Replaced. The Same condition persists within 20 miles of repair. On return visit to dealer, brakes were diagnosed as brake pump failure. Dealer says the pump is back-ordered for several months latest ETA Aug 2023 for "engineering review." The dealer says the Anti-Lock system "should" default to standard style braking without any anti-skid or anti-spin. The truck seems to drive normally except under very heavy braking where the brakes seem to over-engage without additional pedal pressure. I have seen multiple claims for this same failure on the same model truck. The dealer did not specifically state the vehicle is unsafe. However, the dealer cannot issue a NH State safety inspection for the vehicle while the ABS light is on. This renders the vehicle unusable until the parts are released and available.

No accident YET. My Service ABS light and Service Electronic Brake light have been coming on and off for the past 3 to 4 months. I took my 2018 Ram 2500, (odometer 44,000 miles), to the dealer and they ran a diagnostic and found, ABS Pump Motor Control circuit and ABS Control Module failure. The informed me that they could not order the required parts because they are on national backorder. They also informed me that if I was in an emergency braking situation my ABS could fail and not activate. I had a couple of conversations with Ram corporate and they didn't seem all that interested or concerned about my situation. it is my understanding that the parts, required to fix and eliminate this potentially hazardous safety issue, could take six to nine months before they are available. I don't know what to do. Drive my truck, my only means of transportation, and hope for the best for myself and other motorist's and pedestrians? Or don't drive my truck and not be able to go to doctor appointments, grocery stores etc. I almost forgot to mention that Ram did offer to pay for 1 month car rental. What good is 1 month going to do me when it could take 9 months before the parts required is even available? In my opinion, Ram should pick up the tab for a rental vehicle until this problem has been resolved and pay for the required repairs.

At random times I get a chime and dash lights that say service antilock break system and service electrical breaking system. It wont happen for a week and the suddenly it will chime and flash every 10 seconds until the truck sits over night. I have replaced all abs sensors with no change. I’ve taken it to the dealership 2 times and they wont even look at it because it doesn’t show a code. I’ve read countless people online complaining about this same issue and some who have even had break failures. It’s amazing this isn’t a recall item with the number of complaints and lawsuits I’ve read. Hoping this will help get a recall started as the problem is potentially dangerous and incredibly annoying to deal with. It also shuts the cruise control off.

Check brakes light comes on and covers digital speedometer. Dealership doesn’t know when they can get pump to fix??? Am I to drive this truck with faulty brakes until them?

I HAVE BEEN EXPERIENCING ISSUES WITH THE ABS/HCU UNITS. THE WARNING COMES ON EVERY BUMP AND THE ABS SAYS IT IS NOT WORKING I HAD IT SERVICED LAST WEEK 4/18/2023 AND DIAGNOSED AS THE ABS/HCU NEEDS REPLACED AND WAS ORDERED. UNFORTUNATLEY THIS IS ON BO UNTIL 8/16/2023. I UNDERTAND THE 2019'S HAD A RECALL BUT MY 2018 DOES NOT?

ABS hydraulic control unit has went out with 6000 miles. It’s a known issue to ram back order of part is 6 months. There are lawsuits over this issue. Why can’t we have ram fix this safety issue. Does it take people getting killed to make this a recall?

Abs control Module & hcu failure Below will not let me updat date problem started approximately a year ago.

Electronic Braking system continues to fail. No ABS or traction control when towing trailer or RV.

ABS warning light on dash. Took to dealer, confirmed pump defective. Service manager said part back ordered until August 15, 2023. No recall listed. Vehicle is RAM 2500, milage 11,500 approximately, 2018 model. Other components on truck will not operate as well.

The abs and traction control keep coming on and off. Sometimes the truck will sink the Brake. This is a very common problem that happens on these trucks. This is my second time that it goes out on my truck. First time went out at 40k miles now just went out on 76k miles. They’re needs to be a recall set on this as it’s so common to go out on such a short period of time!

HCU is bad, per dealership. Can NOT order part because of backorder on said part. Light will go on and off.

ABS light has been intermittently going on and off over the last year. 67,000 miles and it’s not covered under warranty. Dealership is staying I need an entire new module = $1,900

ABS, TRACTION CONTROL, REPAIR ELECTRONIC BRAKE ALERTS HAVE BEEN FLASHING WITH AUDIBLE BEEPING AND AT TIMES REMAINS LIT WITHOUT BEEPING. Putting a load on the engine or hitting bumps on road seems to cause the warning lights and beeping. This has been going on since June of 2022. Vehicle was taken to shop and diagnosed with failing part (electronic abs brake module) Part was not readily available and waited two months for part for repair. Cost $525.00 total. Did not fix problem now repair shop states the truck needs HCU hydraulic brake fluid pump. Its been EIGHT MONTHS no part available. Truck is in need of repair, no parts available and has limited our use of airstream tow vehicle for travel.

abs brake failure

Hello, my ABS system on the vehicle has failed with only 27,000 miles on this vehicle. Error code C0020-01 Warning system sounds every 5 seconds. It’s very distracting while driving and dealer ship for repair is 2 and a half hours away. No way to disable alarm.

ABS and HCU are in need of replacement parts. Because no replacement parts are available, I have no choice but to drive a Truck with questionable Breaking System, putting me, my family and others at risk, since the brake system is what stops my Truck when I need it to stop or slow down. I use this to tow the family travel trailer as well. This is also very important when brakes are needed to function safely. I have taken the Truck to my dealer of purchase. They completed a diagnostic test and also reproduced and confirmed the problem. The vehicle has been inspected by the manufacturer's dealership Service Dept. The Truck's "ABS SERVICE BRAKE SYSTEM" warning lights and warning tones alerted me of service needed back in November 2022, with just over 36,000 miles. I made an appointment and the dealership serviced my truck in January 2023. Since no parts are available for the repair, I had no option but to pay a diagnostic's fee to have my vehicle released to me, still in need of repairs. The warning lights and signals continue to go off repeatedly whenever I drive my Truck, letting me know that there is a SAFETY ISSUE THAT NEEDS TO BE FIXED!

ABS and electronic brake control warning lights come on intermittently. Dealer diagnosed ABS Hydraulic Control Unit is bad. Code C0020. Truck only has 44,900 miles. Unsafe towing which is what these trucks do.

ABS Module and Service electronic braking system lights come on approx every 3 -5 seconds or stays on continuously. Which results in poor and dangerous breaking performance. Have been told it’s the ABS module and hydraulic servo. Dealer unable to obtain parts from Chrysler.

The hydraulic control box has been bad in my 2018 Ram 2500 since October of 2022. I have tried to order the part through two different dealerships and three times now directly from Mopar, where my order was cancelled. We were originally told the part would be available in December, then March, now it’s August. The ABS and traction control warning lights ding on and off constantly, which is obviously annoying, but much worse- this is our family travel vehicle. We travel with two children and are frequently hauling heavy loads- a large trailer full horses or a 10,000 lb boat. Not having antilock brakes period is a danger, but hauling heavy loads puts us and the vehicles around us at risk.

Warning lights for "Service Electronic Braking System" and "Service Antilock Brake System" appeared sporadically for 3 days, then remained lit continuously. RAM dealer service advisor said it's diagnosed as a failure of the Hydraulic Control Unit. They also advised that the part is on back order and not expected to be available until August 2023, that the truck should not be driven and that I could try contacting Chrysler for more definitive information. I did contact Chrysler, who assigned a "case number" for future reference and invited me to call back in a week if I had not heard from a case manager. I noted that this is an issue of interest to NTSB and am reporting in hopes that you can apply pressure for remuneration for the loss of use and expedite resolution. Chrysler is not much affected but my family is without an essential vehicle and faces significant expense to accomodate this "known defect."

The antilock braking system warning is on randomly and I have already replaced the electronic portion of this unit. I spent almost $1100. Now I am being told the hydraulic portion is bad and is unavailable because it has been sent back for redesign.

Abs light and ebs lights come on randomly. Some days the two lights continuously come on for the entire trip, some days the lights don't come on at all.

HCU antilock traction control unit, warning lights on.

anti-lock braking system (ABS) module that causes the ABS, cruise control and traction control systems to fail

Intermittent service anti lock brake system and service electronic braking system results in loss of ABS system. The dealer has examined it and recommends replacement of the ABS pump motor and control. $1000! I’m told parts are on back order for 10 months. Must be because of all the failures on other vehicles in addition to mine.

ABS system and Cruise Control cut out on my truck constantly when I’m driving. My brakes have locked up while I was driving in the rain almost causing me to wreck. I’ve seen other people having issues with this and their HCU units in these year trucks. Ram refuses to help me.

At approximately 21000 miles the ebs/ads warning light came on -the dash. After a few minutes it went out and has been intermittent since, (currently at 39000 miles). During the summer it comes on less often than during winter/rainy season (Oregon). That said there doesn't seem to be an outstanding pattern except when it is wet (on roadways). Have taken to dealership where purchased three times. The first two the warning light was off when I arrived and they couldn't get it to come on. On the third it was on and after talking to the customer service representative I learned that it is a pro lem they have had to deal with many times (the service representative AND a service tech told me that Ram has a service bulletin notice on how and what to fix, it is that common). I asked why it isn't a service recall issue since it affects a pretty obvious safety device -BRAKES- they could not answer.

2 nd Time I have had antilock brake system failure. I have driven 11920 miles in 18 months since the last failure. This could be catastrophic should I be towing 10000 lbs of tractor and farming implements

Antilock braking system has failed and the alarm continually goes on and off while going down the highway. The dealership has told me the parts to repair this issue are unavailable. This is the second time this occured. The first was at about 40,000 miles and now the second was at 80,000 miles. I have significant concerns with operating the vehicle with the system turning on and off but Ram has yet to provide a solution. Doing some research this appears to be a common problem that everyone with 2500 and 3500 Rams between 2012 and 2018 are experiencing.

Anti-Lock Brake System Failure The following dates for the repairs are as follows: December 05, 2019 1440 miles 5 days out of service April 19, 2021 12662 miles 4 days out of service March 06, 2023 21405 miles 6 days out of service (part backordered/not repaired As of March 06, 2023, the repair of the Anti -Lock brake system on the above mentioned vehicle is at three times and over fifteen days out of service. I am the registered owner and purchased the vehicle from AutoNation Chrysler/Dodge/Ram dealership located at 136 01 Pines Blvd, Pembroke Pines, Fl 33027

Anti Lock Brake light is on. Truck was taken in with only 13,445 miles on it. Was told it needed an ABS Pump Motor Control. Was also told after speaking to mechanics at two other Ram dealers that it would also need the module besides needing the pump. I was told it would be 5 hours labor at $150.00 per hour plus parts. after researching this problem I have come to find that a large number of 2018 Ram 2500 pickup trucks have this issue. Seems like it should be considered for recall. Thanks, Randy Rigatti

2018 RAM 2500 - JULY 2022 - TRUCK MILEAGE @ 48000 MILES THE ABS AND TRACTION CONTROL LIGHT BEGAN FLASHING WITH AN ALERT TONE BEGAN GOING ON AND OFF WHILE DRIVING DOWN THE ROAD. I TOOK THE TRUCK TO DODGE DEALERSHIP TO RESOLVE THE ISSUE THE DEALERSHIP INFORMED ME THAT THE "ABS MODULE" WAS MALFUNCTIONING. I WAS GIVEN A PRICE FOR THE REPAIR AND WHEN I ASKED THEM TO PROCEED, I WAS TOLD THE PART WAS NOT AVAILABLE ANY WHERE IN NORTH AMERICA. I WAS TOLD THEY WOULD HAVE REPLACEMENT IN DECEMBER 2022. I CHECKED BACK IN JANUARY 2023 AND WAS TOLD IT WOULD BE MID-MARCH 2023 BEFORE THEY WOULD ARRIVE. I CHECKED THE FIRST OF APRIL 2023 AND NOW AM BEING TOLD NONE ARE EXPECTED UNTIL AUGUST 2023. SO IT WILL BE OVER A YEAR BEFORE I CAN GET THE ANTI-LOCK BRAKES AND TRACTION CONTROL WORKING PROPERLY ON THE 3/4 TON TRUCK. WHILE I CAN DRIVE IT, IT IS NOT NEARLY AS SAFE WITHOUT THESE KEY SAFETY FEATURES NOT WORKING OR WORKING ONLY INTERMITTENTLY. THERE IS ALSO THE CONSTANT SOUND OF THE ALERT TONE AS THE SYSTEM CYCLES ALMOST NON-STOP BETWEEN WORKING AND NOT WORKING. IT DOES NOT SEEM THAT DODGE/RAM IS TAKING THIS SAFETY CONCERN SERIOUSLY AND HAVE OFFERED NO SOLUTIONS TO RESOLVE THIS KNOWN ISSUE. THANK YOU!

ABS and traction control failed causing me to lose control on an icy road. I was able to regain control without hitting anything or having an accident but now I get an intermittent ABS control module service warning. When this appears the antilock brakes, the cruise control and traction control do not work. Once the light goes off all systems return to normal operation. It is intermittent and unpredictable. Parts are on National back order, I do not think replacing all of these parts is the issue. As dealers like to do… they just replace the whole system without identifying what the issue is. I do not think I should have to pay for replacing parts that are working properly. FCA needs to recall all of these systems and replace them at their expense!

ABS & Traction Light flicker on & off randomly at no specific duraction. I cannot predict when lamps will come on, also cruise control is disabled when lamps light up. I understand this has been an on-going issue for Ram.

C0020-01 "ABS Pump Motor Control-General Electrical Failure" is a trouble code found on the truck I just bought. That seems to be a common occurrence per Ram/Cummins forums. The truck is from a salvage auction, so I cannot say exactly what took place or about personal injury.

My truck was purchased new by me in January of 2019. At approximately 47,000 miles my ABS system failed and I payed to replace the ABS pump/module per manufacturer recommendation. Now in January of 2023 at approximately 95,000 miles the same part has failed on the truck. The ABS system does not function properly causing a substantial safety risk. In addition, I have been told that the part required for repair (ABS pump/module) is out of stock and is not able to be ordered until August of 2023 at which time i will be required to pay out of pocket for the repair. Not only is the time frame for the repair part unacceptable. It is also unacceptable that a quality part has not been supplied. ABS pump/module is not a wear item that should be replaced in such a short timespan.

Dec 1, 2022, Service dept. at Local RAM dealer in Binghamton, NY, diagnosed and concluded that the vehicle requires a new abs hydraulic control unit. PN: 68143491AB was ordered (Order # 1201BP) At that time, Parts were listed as being on Backorder and unavailable until mid January, 2023. ?? Mid January 2023, Part still unavailable, New estimate of part availability was mid March 2023. ??? Mid March 2023, I'm now being told parts will not be available until mid August 2023 ??? At this point, it will be over 9 months to correct this issue.

I have had the ABS hydraulic module replaced several times by Firkins Automotive, now with the same Faulty Hydraulic module failing once again. The dealer had told me after the 2nd time this was replaced it was “junk” parts and there was no permanent repair. When this goes bad you lose all ABS function and traction control causing braking to be unstable and truck to have no traction control. On the dash is the ABS light, traction light and BRAKE light illuminated all the time with warning chimes.

ABS module and traction control starting going off while driving. I took the car to the dealer but refused to fix it despite being under warranty at the time. The ABS and traction control lights go on/off suddenly and my cruise control shuts down and I loose ABS braking which is CRITICAL. this can cause an accident and I am not the only one with this issue. 2019+ Rams have already been recalled for the same issue. I need to get fixed ASAP, I HAVE CHILDREN IN THE CAR WITH ME! Issue keeps getting worse and lights come on more and more frequent, so most of my driving is without proper brakes.

"Electronic Braking Service Required" message and ABS and Skid control light turn on in the instrument cluster and Service ABS come on. The warnings will go off and then re appear over and over. The repair part is not available. It affects other components such as the cruse control.

The ABS module has to be replaced!

Service ABS and electrical brake system failure lights come on randomly and repeatedly. This also disengages the cruise control when it happens. Sometimes the warning light stays on for a few minutes, other times it flashes on and off and dings each time. This is a very common issue for this year of Ram truck from people that I know and from the research I have done. At my previous employer, we had 2 other rams the same year with the same issue. The ABS system will not work with this problem - I was driving and my vehicle skid due to there not being ABS. I have tried on multiple occasions since my truck had about 85k miles on it to get this problem repair. The dealerships all told me they dont have the parts for a repair

The ABS/HCU (Hydraulic Control Unit) failed again. This will be the 3rd HCU installed in my vehicle. The previous repair was completed 10 days ago. I have an open case with Stellantis, since the parts are on extreme backorder (3+ Months). My safety is at risk, because when this component fails, it directly impacts the ABS Brakes, Traction Control, Cruise Control, Parking Assistance, etc. The dealer has confirmed the issue. I am unsure what diagnostics the dealer has performed on the failed part. There are multiple warning lamps associate with BRAKE, ABS, Traction Control, Cruise Control, Parking Assist, Service Electronic Breaking System, etc.

Abs And Traction Control Light comes on and Chimes go off. you lose ABS and Traction Control and Cruse control , This is a know issue with 2018 Ram 2500 . Parts are hard to come by and are very expensive to repair , This safety concern and should be a Ram Recall . I have not taken it to the dealer yet but since it is out of warranty by time , I cant afford the high cost of the repair

The HCU has failed on my truck. This was diagnosed by my local dealer on 26 Oct 2022. I was told this is a known issue with my 2018 Ram 2500. The part has been on a national backorder since the diagnosis was completed. It is now 29 March, and my truck is still not repaired due to the part not being available. In my opinion, based on my own research, this should be a national recall on all of the 2018 Ram 2500 and the manufacturer should be required to cover the full costs of the repairs.

I am affected by issue under investigation with NHTSA Action Number: PE22012. When driving the vehicle traction control and ABS system will turn off unexpectedly and intermittently.

The contact owns a 2018 Ram 2500. The contact stated while driving 65 MPH, the messages "ABS Braking" and "Speed Control Sensor" were displayed. Additionally, the message "See Your Dealer" was displayed the following day. The vehicle was taken to the dealer, where it was diagnosed that the ABS module and the ABS pump needed to be replaced; however, the parts were not available. The dealer advised the contact that the vehicle was unsafe to drive, and the contact had stopped driving the vehicle. The contact stated that the parts had been on backorder for 9 months. The manufacturer was notified of the failure, and a case was opened; however, the manufacturer had not followed up with the contact. The failure mileage was approximately 58,000.

Mileage: 58,000

When driving our 2018 RAM 2500 diesel pickup the message on the dash instrument panel intermittently flashes the message "Service Electronic Brake System." then the ABS and traction control symbols light up on the dash. The RAM dealer diagnosed the problem to the Hydraulic Control Unit (HCU) and said it needs to be replaced. The dealer also said until this is fixed the trailer electronic brakes, truck ABS, traction control and cruise control will not work. Please see the RAM dealer attached diagnosis. The dealer also said they can't order the part until 8/16/2023, the part is currently back ordered because so may RAM pickups have the same problem. So I have a very expensive truck that I can't safely use for what I bought it for, to haul a heavy trailer that has electronic brakes controlled by the vehicle.

Warning messages: Service Antilock Brake System and Service Electronic Braking System. Started at 36,400 miles coming on intermittently then shortly thereafter constantly. Had to remove a fuse to stop consistent chiming noise. Use the engine brake now as the regular brake alone seems sluggish. We no longer have cruise control and it effects the MPG using the engine brake.

Service lights for ABS and traction control systems constantly going on and off during vehicle use, these system failures disable cruise control systems. Truck is at dealer and they have said it needs new hydraulic control unit and ABS parts totaling over $2000 in parts alone, without an idea of when the parts will be available. This seems to be a common failure as I have read many posts of other Ram owners with the same issues.

Anti-Lock Brake system intermittently goes in and out, multiple times per trip. Constant warning chimes are distracting, random disengagement of cruise control without warning, and locking up of brakes. System is not operational and dangerous to operate on the roadway

In December of 2022 my abs light came on. Took truck to dealership to diagnose the problem. I was informed that it was the abs module or abs pump. I was told to replace both parts because the code it’s reporting there is no way to determine which part is bad. Ram has the parts back ordered until August. there is a definite difference the way the truck handles especially with a trailer. The tuck also handles terrible in adverse conditions as the traction control is rendered useless when the abs light is on.

I have a 2018 ram diesel 4x4 tradesman .around 19,000 miles my service antilock brake system light comes on and off and Abs , traction control. Took it where I bought it and of course the parts was out of warranty so they told me they don’t know if and when my parts will ever come in. But if they do it’s going to cost me 1500 $ and change to fix it. I think for the money I paid for my truck it should have a working brake system in place and should not fail with 19,000 miles on it for no good reason. So this is the million dollar question do I drive this potentially dangerous vehicle? Will it stop? Will traction control work? I paid a lot of money for a truck that I can’t even buy parts for if I wanted to fix it. So keep in mind the safety stuff on this truck is designed to work with the weight of the truck and all the torque it has. Oh yea if you’re brave you could buy used ones on e- bay for $150 dollars. What a joke! Sorry for rambling on. Just how important are brakes? I think dodge should do the right thing and fix these issue’s because it’s their product that is failing. I guess I have to drive a potentially dangerous vehicle. Stay safe.

Once during my warranty period on my truck I had a failure wit the electronic braking system and the dealership replaced the Hydraulic control unit. Two years later the same unit has failed again along with Anti-lock module. The replacement parts are are on backorder till August die to high demand related to failures on these units.

ABS, cruise control, stabilitrack and traction control do not function. Constantly ding on and off. HCU/ABS module replaced around 10,000 miles, already out again at 20,000 miles. Part unavailable, eta keeps getting pushed back. Vehicle is not safe to drive. $50,000 yard art.

ABS and Traction control lights on for a know issue involving the HCU (Hydraulic Control Unit) and ABS Module. My 3/4 ton truck has no ABS and no Traction control and I live in Michigan! It is dangerous and RAM has no answers for me as the parts are on back order and no real estimate of when they are available. This is frustrating to say the least. Especially when a quick internet search will show that 1000's upon 1000's of RAM owners are having the same issue. If this is a known problem, why is RAM not fixing it? Why did they continue to produce these trucks with a known safety issue? I ha e filed a case with RAM Cares and nothing is being done. I have been a faithful RAM/Dodge customer my whole life and I don't think RAM will be my next truck. This unresolved and potentially dangerous known issue has taken my loyalty away. This must get resolved! I have been fighting to try and get this fixed since September of 2022!!!! It is now March of 2023!!! I was unable to use my 2018 truck to drive in Michigan winter because it is unsafe to drive. If I get in an accident with my truck, with RAM knowing I have an issue and will not fix it, are they responsible for injury/loss of life/property damage??? My lawyer sure thinks so.

My "Service Electronic Braking System" and "Service Anti-lock Braking System" Lights and alarm has been going off constantly. I have checked with a local diesel repair shop in my hometown and the owner is saying there was a 6 month back order on the "Hydraulic Control Unit" part and all the while my brakes aren't functioning like they should and my truck inspection is now past due.

Constant ABS and ESC failure. truck experiences constant ABS failure. Warning for ABS and Electronic Stability control continually flashes and sends audible alarm when vehicle is operating, multiple times per MINUTE (sometime 20+ times per MINUTE). Vehicle was taken to dealer. Upon arrival at dealer was already aware of the issue and stated this was a known and common problem and that ABS module and HCU would need to be replaced, PRIOR to any diagnostic work being completed. Dealer completed diagnostic work and confirmed ABS module and HCU was defective and needed to be replaced at customer cost as Chrysler/Dodge/Ram refused to voluntarily cover/recall this part even though it was widespread known issue. However dealer stated that parts were on National back order and they had a long wait list. Dealer could not give timeframe but stated it would be 6+ months, that was over 1 yr ago. Part still shows as back order. My research has confirmed dealer statement that this is common wide spread issue for this make/model/yr due to defective parts. Any assistance possible would be appreciated at Ram continues to drivers at risk everyday by failing to voluntarily recall part or even make parts available so repair can be completed

I am filing a complaint because my 2018 Ram 2500 has been in the shop waiting for the ABS hydraulic unit since January. I don't understand why there are so many people in need of this part, I am a cattle rancher and I need my truck to haul my cattle to livestock shows. I was told by my service repairman that it would be April then they called back and said August. This is totally unacceptable!!

The ABS system is malfunctioning due to bad abs modules that most 2017 and 2018 ram trucks had issues with. This is causing the truck to have no abs or traction control.

I keep getting an intermittent error code on my vehicle C0020 - ABS Pump Motor Control. General Electric Failure After doing some research on the internet it appears that there are a lot of 2017 & 2018 Ram 2500 owners with the same issue

This complaint is based on the repeated failure of the vehicle's ABS/Traction control system and the lack of a repair solution from Ram. The failure starts as an infrequent (once per trip or so) fault and immediate clear of the ABS system with an audible alarm and dashboard message. Over the course of a few hundred miles the problem worsens to the point where it it faulting as often as every 1-1/2 to 2 seconds. (It is like driving with the seatbelt warning going off). Sometimes it will stay faulted or cleared for several seconds to minutes at a time. In the beginning of the failure process it seemed to go away once the engine got fully warm, after about 10 minutes of driving. This problem was diagnosed and repaired at a diesel specialty garage with replacement of the ABS Control Module and Electric Stability Control Unit. Reprogramming was performed by a Ram Technician. After about 7000 miles the problem returned, following the same failure pattern. The same shop inspected and and repaired a loose connector, another known deficiency in the system. However, this didn't fix the issue. The alarm started before I moved the vehicle (after paying for the repair). At that point I was told that there was no solution, and in fact there were four other trucks there with the same issue. The parts are under warranty but I am left paying for labor to install equipment that seems will fail fairly shortly. And I am left with a completely unreliable ABS system. The failure doesnt seem dependant on speed, road conditions, outside temperature, or towing/empty.

The abs traction control lights keep coming on device abs service electric brakes I pull a camper afraid I may loose my brakes and no parts available

In November of 2019 our ABS & ESB Warning lights keep coming on and off (code C0020.01 ABS pump motor control general electrical failure). The dealer replaced P/N 68347098AB & 68143491 an this resolved the problem. In November of 2022 the same ABS & ESB Warning lights started coming on (same code C0020.01 ABS pump motor control general electrical failure). I have been told this is a known problem with our Vehicle, and that the parts are hard to come by. Why has this issued not been resolved? We tow a Travel Trailer, and this cannot continue to happen. How can this be resolved quickly?

The ABS and Traction Control lights constantly blink on and off while driving, causing cruise control to shut off and an audible ding inside the cab, every time the lights flash. I am concerned that since the ABS module is malfunctioning, that the brakes may lock up or not engage when they are supposed to, and I will not have anti lock feature if I happen to need it. Aside from the annoyance of the dinging constantly, and the cruise control disengaging, I feel this is or will become a serious hazard. I have read that RAM has had several ABS related issues, and I don't understand why this is not recalled yet.

Abs and traction control flashes on and off intermediate. Took to dodge dealer in New Boston, TX. Needs new HCU but is on national back order. When this happens the cruise control doesn't work and wheels will lock up if I hit the brakes to hard to stop.

The HCU is went out and Mopar has a stop order on parts

service anti-lock brake system and service electronic braking system lights flashing on and off while driving. While these lights are flashing the traction control is disabled. One instance I was driving down a hill and the service lights began to flash. As I was applying the brakes, the brake pedal locked up. This instance did not result in a crash. I have brought my 2018 ram 2500 to a local dealership that said my ABS hydraulic power unit needed to be replaced but they cannot replace it as there are five similar vehicles on the lot that are currently waiting on the same part. I brought my vehicle to a local diesel shop that also informed me the same thing.

1) Brake Anti-Lock Control Unit (Three times. (9/17/19 (5000 miles), 11/12/21 (21,527 Miles), 3/20/23, 33,000 miles). 2) Traction Control fails, Anti-Lock Brake System fails, and Speed control if engaged kicks off! All which could lead to ineffective braking, loss of control and inadvertent speed control disengagement. 3) Yes. Cameron JCDR dealership, Cameron, Texas, Mac Haik JCDR dealership, Temple, Texas. 4) Not at this time. A case has been started through Ram. Case # 85736004 5) Yes. All messages appeared at various times prior to me getting the vehicle to the dealerships for maintenance.

Service abs system light is on as well as service electronic braking system. My truck no longer has antilock brakes. Cruise control does not work. Dealers do not have parts available to fix the issue. This is a very common and well documented issue with these trucks. This was an intermittent problem to begin with but is now permanent. They should be recalled.

Hydraulic control unit was replaced July 2020 (ABS traction control lights coming on MEANING, NO ABS NO TRACTION NO 4 WHEEL DRIVE.) Hydraulic control Unit not working AGAIN. I have NO ABS, NO TRACTION, NO 4 WHEEL DRIVE, AGAIN. CHIME GOING OF CONSTANTLY AND DEALERSHIP HAS HAD "PART ON ORDER SINCE JAN 2023"

HCU, ABS Modules. Inspection Is Available Apon Request. Concern For Safety With Hard Brake Pedal, Not Stopping As Required. Modules Do Not Respond To Hard Braking Like Described. Speedometer Not Reading. I Changed The Cables To The Wheel Hub With Still No Response. 42,600 miles In It, No Accidents. Problem Started 8mo. Have Not Driven For 3mo Now. Safety Not Confident. No Dealer, Mechanics Only A An Advanced Code Reader Scanner. Engine Light, ABS, Car/Lane Symbol Display.

Abs and traction control light, warning comes on and off and says service system

Truck throws ABS and Traction control warning codes intermittently and when hitting bumps. On a six hour trip today it threw the codes 50-60 times. Worried this could cause serious accidents if features do not work as they should.

ABS module/ HCU. Abs light & traction control light is on. Was driving down the road when they lights started flashing. Have been waiting for parts for 4 months because its on national backorder.

Abs light comes on turns off cruise and traction control, brakes becomes spongy and vehicle gets pushed through refle light bey trailer. Near miss accident.

Abs and traction control lights are illumated when towing a trailer it would turn off trailer breaks I have taken it to auto shops and they state its the abs module or hydraulic control unit. When normally driven abs will be intermittent and can pose a safety hazard.

ABS warning to service anti-lock brakes. Mechanical brakes continue to function. The ABS system continually warns and chimes about the electronic ABS system not working. The ABS fault code is C0020. A Chrysler/Ram dealer has attempted to repair it once.

ABS light and Traction control lights go on and off constantly. Issue started around 38,xxx miles. This is a known issue in the ram community and Chrysler needs to recall these trucks to make the proper repairs to the HCU and ABS module. This is a major distraction while driving as the lights and chimes constantly go on and off and I cannot focus on the road. when these lights come on the ABS system is disabled, all traction control is disabled as well as my cruise control.

Abs braking system has been flashing and traction control light flashing. My left front wheel started grinding and smoking out of the blue when driving today. No problems with brakes before that. Cruise control doesn’t work. And four wheel drive service light is flashing again!! The four wheel drive sensor was replaced once already a couple years ago.

Our truck has the AB HCU module light showing with a problem.Constant dinging while trying to drive. The part has been on backorder from the local Ram dealership since October 2022. We have been told that it's a known problem with Ram diesel pickup trucks. Please help by providing a recall. This is ridiculous on a truck with less than 45k miles.

Was driving vehicle on a rock road, when rounding a slight curve in the road, the antilock brake system light and the traction control lights both illuminated at the same time. The rear end of the truck began to slide due to having light pressure on the brakes and I was pulling my fifth wheel camper. Fortunately there were no injuries or damage to the truck or the camper. I washed off the mud when I got back to a hard surface area that had a car wash available and continued on my journey. Approximately 30 more miles later on the same trip both warning lights came on again. I immediately pulled over to read the message warning that was up on the dash to see if I could continue with my journey or not. After reading the message on the display in the truck, I decided it would be safer not to continue with my journey with that truck due to the safety issues and possibility of injury or death to me and my passengers, or another vehicle that I may encounter either head on or from behind. I had a friend of mine bring his fifth wheel truck to pick up my camper and return it back to my home. I had to cancel my camping trip for that week, which cost me approximately $400 out of pocket and then I had to pay my friend gas money to bring my vehicle home for me. I placed a call to the dealership nearest me and they advised me it would be $1,000 to begin any sort of diagnostic procedure on the I have now been driving the vehicle only unladened with any sort of extra payload, the light will come on and go off and come on and go off multiple times some days no times other days. I am retired, and a long-term covid patient, I do not have the financial resources to take a vehicle to a dealership to have them charge me absorbent amount of money when this clearly should be a safety recall on this vehicle. I have lost use of the vehicle for the intended purpose of telling my camper and boat, the manufacturer needs to be advised of this and give everybody repairs to make it safe to use.

Service Lights on dash. Service Antilock brake system, SERVICE electronic braking system. Defective part is HCU, hydraulic control unit. Part has been unavailable for over a year and part availability always pushed back on estimated arrival date. This safety issue needs to be addressed with a recall.

The ABS failed while on hwy. Researched, and break loss is a common problem in this gen pickup.

At 9955 miles, the WARNING CHIMES were activated on this vehicle, and the error message on the dash indicated 'ABS FAILURE' and/or 'SERVICE ABS SYSTEM'. I checked the OBDII codes and saw code C0020, 'ABS pump failure and/or Hydraulic Control Unit Failure'. Took vehicle to the stealership, who also checked the OBDII scan and replaced both the pump and the HCU with the SAME SUBSTANDARD COMPONENTS that were previously used. Less than 6000 miles later, the SAME PROBLEM BEGAN OCCURRING AGAIN, along with the SAME OBDII failure code. Took vehicle back to stealership, who confirmed that this was the SAME PROBLEM that occurred at 9955 miles, but that they couldn't order the 'new and improved' parts from FCA until Jan, 2023. Returned to stealership in March, 2023, and was told these ABS parts were now on backorder. Filed a complaint with FCA Customer Care, who then sent the 'backordered' parts to the stealership two weeks later. The stealership WILL NOT INSTALL THE PARTS UNLESS I PAY FOR THE PARTS AND LABOR in spite of a RAM TSB describing this failure and a Texas class action lawsuit against FCA for failing to address these ABS safety problems affecting thousands of RAM HD truck owners. FCA still has not issued a recall on the faulty ABS components. EVERY TIME THE ABS WARNING CHIME OCCURS (OFTEN EVERY 10-15 SECONDS), IT DISTRACTS THE DRIVER AND CANCELS THE CRUISE CONTROL, AND, OF COURSE, THE ABS SYSTEM STOPS FUNCTIONING.

2018 Ram 2500 6.7L Cummins. While driving, at any speed, “Service ABS” and/or “Service Electronic Braking System” flashes rapidly and intermittently on gauge cluster display. During this, the “Traction Control Fail” icon displays. Additionally, the cruise control will automatically disengage (creating a safety issue through increased risk of being rear ended while at highway speeds) and the warning chime activates constantly leading to distraction while driving. The truck is essentially undriveable. It is incumbent on the manufacturer to remedy this problem. It’s a shame I cannot use this truck more than a few miles at a time. How am I to stop with my family of 6 inside the truck, towing a 10,000 lbs trailer on a rainy day at interstate speeds without functioning ABS? This is a serious design flaw and I encourage NHTSA to continue their investigation into Ram’s process for remedy as soon as practical. Strongly recommend mandatory recall.

abs trailer brakes traction control works on and off

2018 Ram 2500 Diesel Antilock Braking System light Traction control light Park sensor warning 4 wheel drive unavailable light All issues are intermittent. Issue seems to be a reoccurring issue according to my research. Vehicle has not been inspected but has had codes scanned when the issue occurred. I feel with the brakes being at an intermittent state it puts myself and others on the roads at Rick if they were to stop working with no indication.

There seems to be a huge ongoing problem with ABS pumps and control modules for this model vehicle. I can find pages and pages of issues online for the same truck. The 'service brakes' warning comes on and off intermittently and I managed to replicate the fault after several months long enough to get it diagnosed. I am told the following parts are the issue: 68347098 - AB MODULE AN 08035030 68143491- AB CONTROL A 08035030 I got the truck diagnosed in January but was initially told Mid March for the parts and now am being told August - which would mean no functioning ABS on my vehicle for 8 months! And no guarantee the delivery date won't creep again. This is unacceptable for a safety critical component and clearly shows a fundamental flaw with the parts as they can't seem to make them faster than they are failing. I can find many reports of these happening from as early as 14,000 miles and with the replacement parts also failing.

ABS traction control warning comes on intermittently. This causes cruse control to disengage intermittently, and causes braking and traction to be compromised at times

RAM has a “known issue” with the ABS system, mainly the Hydraulic Control Unit, with the brake systems in at least the 2018 model year heavy duty trucks. They redesigned part number 68143491AA and released a new version, 68143491AB. However this part has been back ordered. I have waited 3 months so far, and have been told earliest to expect the part is August 2023. Others have waited more than a year already. Without the part, the truck rapidly flashes warnings on the dash. Additionally, the ABS, traction control and stability control systems are inoperable. For a 10,000 lb GVW truck with 800+ lb/ft of torque, this makes for dangerous handling for wet roads. I don’t need anything for free, but something should be done to make RAM accountable for the dangerous situation they are forcing on the owners of their vehicles. These parts need to be manufactured quicker and made available for purchase by effected customers ASAP.

ABS pump motor control general electric failure found by dealer code C0020-01 per dealer needs hydraulic control unit. Warning comes on ABS unit need service. Safety concern braking system could fail. Mileage at time of dealer diagnostic 28572 keeps reoccurring current mileage 29791

My ABS light has been intermittently illuminating my dashboard since December. I took my truck to the dealer on 3/13/23 and it's still there. Per the dealer, it needs an ABS module and the Hydraulic Control Unit. I had already replaced the HCU over a year ago so thankfully it will be covered by the dealer, but the ABS module still needs to be replaced and was told that the HCU won't be available until August. Dodge needs to address this. Obviously, this is an ongoing issue and it's not safe to drive and puts myself, my family, and others in potential danger if the electric brakes aren't performing properly. Also, I was advised by the dealer that the ABS module going out has caused the HCU to go out and is an ongoing issue that they have been seeing with no known cause.

ABS has been a non-stop issue on this truck since purchase. It has been "fixed" 3 times and currently is not drivable due to no ABS, traction control, cruise, or 4 wheel drive available. aBS module is on backorder for 3 months.

ABS Control Module failed and was replaced with part #68143491AB. Truck was purchased for plowing. Without anti-lock breaks and traction control, myself and passengers were at risk , and my ability to plow more than a few inches of snow was nearly impossible. Living on a dead end private road, plowing for neighbors to access main roads was not possible, putting neighbors and family at risk during winter emergencies. The part was back ordered for several months, delaying the repair and extending risks. The vehicle did provide an alarm to audio alarm of this problem which was a distraction throughout the part backlog period. The cost of the repair to me was $1, 119.95. This should not have occurred on this truck that had less than 40,000 miles.

The ABS system warning lights have come on and system not working, had it checked and was told it was the ABS controller assembly pump motor, code # C0020-01, and that it was a common problem with this vehicle. I was told i should report it.

My 2018 Dodge Ram 2500 has a known faulty issue with the HCU/ABS (hydraulic control unit/Anti-Brake System). My ABS light continues to flash while driving. This problem is very well known with 2017-2018 RAM trucks. The local dealership stated that the part is on backorder till August. This will be $1,000.00 + fix from dealership. This has been an ongoing issue, not just myself but many RAM owners, that happens at various times. The issue occurs at various speeds, when I hit a bump, or when I hit the brakes. This issue needs to be resolved with Dodge Ram and a recall issued.

The anti lock brake system module failed in September of 2022 and Ram is still unable to provide a replacement part. The brakes lock and the truck slides easily when pulling a trailer in rain. This is a VERY common problem and should be addressed by a recall.

My ABS and Traction Control fault lights came on in my dash. I was towing a camper that weighs approximately 10,000lbs. and the trailer brakes did not function while this fault is active. Without the operation of the trailer brakes this is a very dangerous situation to stop that much weight. Had the code checked. Code C0020-01 is what was displayed. While this code is aluminated the trailer brakes do not function.

The Service Electronic Braking and Service Traction Control comes on intermittently while operating the vehicle. I have had it fixed once under warranty. It is not a safe vehicle to operate without traction control and abs.

In November of 2022 I reported to the dealer that the ABS and Electronic Brakes System warning lights were intermittently coming on an off. The dealer diagnosed the problem as a hydraulic brake control module failure, but stated that the part(s) were back ordered until March of 2023. This seems to be a common problem with this model and year of truck, but Chrysler (FSA) has done nothing to resolve this safety issue. It's been 5 months now and I this issue could cause a crash or worse.

ABS light and Tracking control lights flicker on and off constantly. No warnings just came on one day. I have 38,000 miles on my truck not very many for warning lights to come on. I cannot use cruise control as well as about half of my controls. Including tracking control which is now permanently off and is a major hazard! Took it to the dealership in Concord, CA and was told the control module is bad. With no time frame to fix. Probably will be a fix once my warranty is up so the dealership is not liable to fix my truck. A quick search online shows this is a problem for this vehicle.

ABS Traction control turns on and off as truck is driven. Sets code for ABS motor. Called dealer was told to drive until light stayed on.

ABS HCU module was intermittent in 2020, replaced HCU Has been working fine till now. looks like I was sold the old part number. 2 years later it is throwing fault codes again. RAM has an updated part number now. This should be a recall and I shouldn't have to pay to have it replaced for the second time.

Intermittent ABS Service electronic braking system & service antilock brake system

Antilock Braking system warning flashes on and off constantly. Diagnosed as HCU (Hydraulic Control Unit). DTC code is C0020-01 Researched and found RAM TSB S2005000004. Also found that MANY of these have failed. Not only that, but my dealer cannot even order a replacement part until late June 2023 and it is March 4th, 2023 now. Then, when it is ordered, may still take another 3-5 weeks to receive. My point is. This needs to be treated as a recall. Obviously there are major issues with this component, so much so, that you can't even buy one to replace the failed component. In the mean time, I have vehicle without ABS braking.

A warning light comes on that there is a failure with the anti lock brakes and electronic braking system. The cruise control will also fail to work. When the roads where wet the other day, i was sliding to avoid hitting deer that began crossing the road. It took longer to stop than it should have. I'm concerned that living in Michigan with the inclement weather, it may cause a accident that could have been avoided. The vehicle was checked by a mechanic who said the control was going out. The incident started some last summer (I only have 22,000 miles on my truck) but it is intermittent.

Message appeared on truck display while driving in a snowstorm, "Service Electronic Braking System". Loss of ABS/EBS control while navigating dangerous roads. Code C0020-01, ABS pump motor control is faulty.

Abs/traction control lights come on and disconnects the cruise control dangerously wen pulling a trailer, code is c0020-01 this is a very common issue with these trucks parts unavailable, I’ve talk to many other owners with same issues please address the problem before someone gets hurt thanks.

Began receiving a warning message of " service ABS breaking system / service electronic braking system. Contact dealer " while message is displayed, ABS and traction control will not work. Dealer diagnosed as a known issue with a faulty ABS controller and/or hydraulic control unit failure. The dealer said there was no recall even though it's a known issue so the repair is the customers responsibility. The cost of the parts if available, plus the cost of labor is forcing the truck to be operated on daily basis and quite often towing heavy loads in a condition that is extremely unsafe.

The ABS system has failed again on this vehicle. It was repaired by the dealer at 23,836 miles initially. The ABS module is in need of replacement again at approx. 58,000 miles. The ABS and traction warning lamp come on and off intermittently while driving.

Driving along freeway to visit family, cruise control engaged, travelling 65 mph, when all of a sudden several messages flashed on the dash to "check electronic braking system", and traction control disengaged light and service light came on as Cruise control shut off. after a few seconds lights went out and system returned to normal. Repeated several times on way back home (3 hr drive) and had randomly happened since almost every time I drive the truck. Had similar situation a year after I bought the vehicle, 11/2020 @6600 miles, local dealer replaced HCU. This can potentially leave me without Traction control and ABS when I need them and could cause an Accident. I'm waiting for dealer to get other parts in for a covered warranty repair, (Been waiting since Nov 2022), and have them fix both, again, but it renders my truck useless- dangerous to drive until then.

Chrysler issued a recall involving the 2019 to 2022 Ram 2500, the 2019 to 2022 Ram 3500 Chassis Cab with GVWR under 10K lbs., and the 2021 to 2022 Dodge Durango due to an ABS Software issue. They have completely ignored the 2018 RAM pickups with an ABS Controller issue. We have had a part on backorder for months and the dealership we work with has 14 of them on backorder. Research on the internet has confirmed hundreds of other RAM owners of 2018's have the same issue. The ABS warning message and ding goes on excessively. In an hour's drive, it might go off 12 to 15 times, warning the ABS system is not operating. It also causes the Cruise Control to cease working. We need some help on this issue.

At 15,000 miles i had Service ABS, Service Electronic Brake System and warning lights activating at different times/ conditions. When this happened the cruise would also disengage without warning. Brought to the dealer and the ABS control module and pump were replaced under warranty. At 75,000 miles the Service ABS, Service Electronic Brake System and warning lights were activating intermediately at different times/ conditions. Again the cruise would disengage without warning. I had the code checked at it was listed as code C0020-01 "ABS Pump Motor Control- General Electrical Failure." which i believe is the code that was thrown at the 15,000 mile mark. Right now i am waiting for the part to become available for replacement.

The Hydraulic Control Unit (HCU) has failed for the second time on the truck which causes the ABS, traction control, parking sensors and cruise control all to fail, along with the electrical baking system for pulling trailers. This is the second time this has failed. The first was replaced at the dealership on 07/22/2021 when the truck had 29,983 miles on it. It has failed again with 42,125 miles on it, and the dealership will not cover it as it is not listed as a warranty item.

My vehicle has 45347 miles. It started throwing "Service Electronic Braking system " and "Service Antilock Brake system" messages intermittently. While driving on highway, truck would abruptly throw these messages and turn off ABS, EBS and also cruise control. It appears to be a very common safety issue with 2018 RAM 2500. I took my vehicle to the dealer but he couldn't read the codes because they were off and didn't come on. This is a safety issue for driving a one ton pickup truck and especially if driven in wet conditions.

FAILED ANITI LOCK BRAKES MODULE..... I APPLIED THE BRAKES FOR AN EMERGENCY STOP SHORTLY AFTER THE CODE CAME UP FOR ANTI LOCK BRAKE FAILURE AND TRACTION CONTROL. HAD THE CODE LOOKED AT CAME BACK AS FAILED BRAKE MODULE. CODE WAS CLEARED AND THE PROBLEM WENT AWAY. SHORTLY AFTER I WAS INVOLVED IN ANOTHER INCIDENT WHERE THE ANTI LOCK BRAKES DID NOT WORK AND AGAIN THE ANTI LOCK BRAKE MODULE FAILURE CODE IS ON THE TRUCK. THROUGH INCIDENT THE BRAKES LOCKED UP ALL 4 WHEELS RESULTING IN LOSS OF CONTROL.

My 2018 ram 2500 started having the service the electronic brake system or service antilock braking system, it also showed traction warning light on instrument cluster message come at about 45,000miles it came on every time I’d hit a bump in the road sometimes it would stay on for days on end and not go out other times it would come on every few seconds and back off as quick as it came on, I got a hold of the dealer I bought truck from and scheduled an appointment, at 50,281 miles my truck was diagnosed at a charge of 112.58 and was told that “ abs pump motor needs replacing and replacement part not available at this time”, I asked if this is a new issue and if they seen it before to be told” there was also a lot of other rams coming in with this same issue” . After this discussion my eta for the part was December 18 of 2022 heard nothing so reached out to the dealer on December 23 of 2022 only to be told that it would be in January 18th of 2023,on January 18th called the dealership only to be told it will now be in on March 18th of 2023,this issue is not getting resolved and every time this warning comes on it shuts off the cruise control,traction control and the ABS which in my opinion is something I could really use in the Wisconsin winters,I’m really hopeful that you will remedy this situation this is a serious safety issue and in my opinion an accident waiting to happen if it hasn’t already

Abs control module failed at 4,000 miles on 2018 ram 2500 causing traction control and anti lock brakes to be disabled and warning lights to turn on.

Total brake failure. Went to park at the bank (luckily was only moving at 4MPH) Went to stop and the brake pedal sank all the way to the floor. I quickly pumped them and was able to stop only inches from going through a fence. Was able to pump the peddle till it was solid again. Has not happened again since then.

The ABS/Electronic Braking system failed before the truck even hit 50K miles, but I haven't been able to get a replacement module and have been told that these items are on back-order until an indeterminate time. However, the Electronic Braking System and ABS warning lights go off on my truck daily, especially if I drive over any rough roads or bumps. I've been having trouble getting my truck inspected because these parts can't get replaced. I've also noticed that the cruise control system on the RAM 2500 doesn't work sometimes and sometimes it comes on but it doesn't want to switch off when you hit the brakes, so I had to stop using it for fear it wouldn't turn off at all at some point.

Ram has had many issues reported on this item. It has been a known issues yet Ram has not taken proper action to resolve this problem. Intermitted warning lights on dash, service electronic brake system.

ABS Hydraulic Control Unit failure, warning on dash, notifying loss of ABS braking, as flashing notice which turns off cruise control and removes speed register from dash while ringing interior alarm consistently. This safety issue reduces safe braking on wet/icy conditions, and has occurred on the 2018 Ram 2500 Tradesman vehicles with mileage between 15,000 to 55,000 miles. Please acknowledge receipt of this complaint. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”

ABS Code C0020-01

ABS / HCU System Failed. My safety was directly impacted. I was driving 70MPH on the expressway and had a SUDDEN deceleration, which nearly caused a rear-impact collision. Various warnings and lights on the dash lit up with "Service Electronic Braking System". When the ABS / HCU system has an issue, it deactivates the cruise control, ABS System, traction control, and parking detection system. The dealer is able to verify the issue. I have taken the truck to the dealer, who is reporting a part shortage and multi-month backorder for the part. This is a huge safety issue, and could have killed me and my children. This should become an immediate recall since it directly impacts the safety features of the vehicle as well as the cruise control system, which may suddenly deactivate and cause sudden deceleration. Various warning lamps display. BRAKE, ABS, Traction CONTROL.

“SERVICE ANTILOCK BRAKE SYSTEM” and “SERVICE ELECTRONIC BRAKING SYSTEM” lights come on and off repeatedly.

The notification on the dash reads “Service Electronic Brake System” The truck makes a constant dinging sound while the truck is in motion. My mechanic ordered the brake control module back in October 2022 and the part is still on backorder.

Having problems with my ABS Module antilock brakes system,took my truck to Dealership , and there respond was this part was in back order and no recall, its being 5 months .my issue is for the Safety of my Family and myself on the Road,I dont want to have and accident and get somebody Hurt or worse,and my family Im very concern of Driving this truck every day. need MFG to correct this PROBLEM.

The ABS/HCU control unit failed at 16000 miles and was replaced. At 30000 miles, the same part has failed again. The parts for repair are not available at this time. Hopefully an upgraded part is being designed to fix this failure. I am afraid to drive this vehicle in wet conditions or while towing as a faulty Anti Lock Braking system (ABS) could cause a loss of control. The dealer has diagnosed the failed unit in both instances and has the parts for repair ordered. The truck has the service ABS/Traction Control alert pop up on the dash readout.

Vehicle was repaired once under warranty for the ABS and Traction Control Light coming on and off consistently. Approximately 25000 miles later the truck started doing this same thing again. ABS and Traction Control Light will consistently come on and off over and over. Will happen when I brake, accelerate or let off accelerator, and on bumpy roads. Sometimes it comes on while on the interstate with cruise control activated causing the vehicle to come out of cruise control. Dealer states it is a common problem and my parts have been on back order since October of 2022, It is now February 19 2023. Dealer states it is a 1400 dollar repair.

My ABS and traction control lights came on my dash. It gave a message to service electronic brakes. The lights would come on, followed by an audible ding. Then it would go off, again with an audible ding. On, and off, on and off again. Sometimes it will stay on, some times it’s intermittent. It happens under all conditions, start up/running at temp, bumps/level roads, during braking/driving at speeds, and in wet/dry roads. The only performance issues I’ve clearly noticed is the traction control not working on wet grass. I’ve had to use four wheel drive to get out of the situation. I’m questioning the safety of my vehicle at this point. I have been researching and see that this is a highly discussed issue and a known issue, and has parts availability issues. I saw where NHTSA had opened an investigation, so I wanted to report that it is also a problem for me. I plan on contacting the dealership this week.

The Service ABS light come on, around 32,390 miles just out of the 3 year/36,000 mile warranty! The cruse control no longer works! The traction control light is on with the ABS light! Beeps on and off and on and on very annoying!!! Had the truck scanned by my local Mechanic. ANTILOCK BRAKES C0020-01 ABS PUMP MOTOR CONTROL-GENERAL ELECTRIC FAILURE-STORED. The truck is available upon request.

The abs module and hydraulic control unit has failed. This means that my safty and others on the road is put at risk because during heavy breaking you can loose control of the vehicle due to the truck anti break system does not work. Also the traction control does not work which also will cause you to loose control.

Vehicles “service antilock breaks” code is flashing. Began doing this with under 15,000 miles. The cruise control and the anti lock breaks don’t operate as a result. Problem started as intermittent and is now a constant issue. It appears to be the hydraulic break control unit, and is a very common issue with this year of truck.

The service brake system and service antilock brake system light came on. This light comes on quite often and shuts off intermittently. The pick-up no-longer has anti-lock brakes, traction control, or stability control. When light is on cruise will not work which if it set and light comes on it will shut-off and cause vehicle to drop speed which could cause an accident. Last time I drove it it felt like the brakes were spongy or not really engaging, which almost cause me to go through stop sign on to a highway. I have not had a chance to take it in to get checked yet, and the parts to repair I believe are back ordered.

Brake ABS and traction control system is malfunctioning due to failed ABS Hydraulic Control Unit as diagnosed by Ram dealership. Malfunctioning includes illuminated warning lights for ABS and electronic braking system. Malfunction also effects use of cruise control system. Vehicle is available for inspection upon request. Safety is at risk due to unknown effects on use of ABS system. Problem has been diagnosed and confirmed by dealer. Warning lamps have been intermittently illuminated for several weeks.

Abs lights on traction control lights on constantly off and on alarming. Making it un drivable Was told it's very common issue currently being investigated by nhtsa. Dealership confirmed HCU Pump control module. Costing me quoted $1750 for repairs and unknown when part comes in. Earliest is end of March. All the forums and videos I've seen that this is constantly happening and this needs to be recalled. I believe it already has on the 2019-2022 models. Safety concern with no abs or traction control. Also cruise control won't work.

Multiple ABS pump and ABS hydraulic control unit failures. Components have been replaced and replaced components failed also after a few months.

ABS and Traction Control system failures. Available for inspection Lack of ABS makes controlling or stopping difficult in the winter, higher potential for collision in slippery conditions. Dealership has confirmed that ABS and HCU modules are cause. Service traction control and antilock brake system messages displayed intermittently starting around July 2022 at 40,000 miles, and then continued until total failure.

Abs and traction control light goes on and off shuts the cruise off. Was told that it could lock brakes up and wasn’t safe to drive. Dealer doesn’t have one and the soonest they were going to be shipped was March 15th maybe.

Abs light blinking on and off while driving and parked.

While driving my truck in the interstate in the rain, I went to change lanes and accelerate to pass a slower moving vehicle. As soon as I hit the accelerator the antilock brake system warning light illuminated and the rear wheels broke traction. The rear end of the truck began to slide and I nearly lost control. I had not had any problems with the brake system prior to this incident. From that point on the service abs/brakes light and alert noise began to activate on and off intermittently and the traction control is inoperable. In doing research this is apparently a known issue with the hydraulic brake control unit. I was fortunate to be able to maintain control of the truck.

The vehicle continues to have ABS control module/electronic braking failures. I was told by the dealer no replacement modules are available, and could be back ordered for up to 6 months. Research online indicates this is a very common problem. This is a clear safety hazard. A recall needs to be issued for these failing parts. I had these parts replaced one year ago and they already have failed again.

The ABS and traction control service lights and alarm come on and off and shuts off cruise control. stops coming on for days at a time then happens again. Been told brakes could lock up and trailer brakes may not work

Abs unit failed during a panic brake situation and I hit a vehicle. No injuries. Parts have been on backorder for months.

System constantly chimes alarm on and off for Service electronic braking system, Service Antilock brake system. The HCU seems to be in short supply because you cannot buy it online or from a dealership they all show out of stock or backordered with no eta of when it will come in. I feel like it only a matter of time before it causes an accident. Seems to be a known issue with RAM. I have a video on my phone of it going off constantly

The abs and traction control and service electronic brakes system flashes on and off. Truck only has 65,000 miles on it now and it start around 60,000 miles.

2018 RAM 2500, both the hydraulic control unit and the anti-lock brake system module had to be replaced with only 46,000 miles. I would get a warning to "Service Electronic Breaking System while going highway speed with the cruise control on. Once I receive the warning, it would disengage the cruise control without any notice. That is very scary and dangerous.

The abs and traction control lights come on and go off intermittently. I took the truck to the dealer they said it need a new hcu which costs 500$ and 1000$ for labor the truck has 27000 miles on it and is out os warranty. The part need is on back order. I feel this is a defect and there should be a recall. Thanks for any help you can give. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

ABS SERVICE BRAKE MESSAGE APPEARS AND CLEARS. THIS LAST 20 MILE TRIP IT WENT OFF OVER 20 TIMES.

In December 2022 the ABS warning light came on in my truck. Dealer confirmed that the ABS Module needed to be replaced. My dealer also said that there were several other like vehicles that they were holding onto for the same reason. Internet search revealed that this is a known issue with Ram. The real problem is that the part is apparently on a long backorder. There are reports of people waiting 6 months for the module. I was initially supposed to get the part on 18 JAN but that date shifted to 15 March and the dealer is telling me it's unlikely we'll even get it then. Two issues as I see it. 1- Ram has installed defective ABS modules in its trucks and has no way of replacing them. My truck is a 2018 with only 43000 miles on it, should ABS modules be going bad? Should a vehicle owner have a reasonable expectation that the company will be able to fix/backup it's products? The other issue that really pertains to NHTSA is that I've heard from multiple people that, due to the long wait times for the part, they're simply pulling their vehicles out and using them. Most people (like me) are struggling with being down a vehicle for months at a time. Many require it for work. The brakes still function but the ABS will not (nor will the cruise control). If the reason that vehicles all come equipped with ABS is for safety, it makes sense to me that having vehicles on the road without it is unsafe. But what are people to do when Ram will not provide a part? I'm working my issues with Ram customer care but they are not helpful. There is no buyback program for backordered parts. There is no rental or loaner program. My insurance will not cover a rental because it's a backordered part. There is no anticipated end to the parts wait and this is encouraging people to drive unsafe vehicles.

The ABS - Electronic Braking System fault light flashes on the dash while driving. This could cause a crash during hard braking, rain slick roads, or while towing. The truck has been to the dealership about this concern and was told the parts are not available for at least 6 months. I was also told by the dealership that the manufacture who makes the parts is not longer in business and there is no plans for Ram to source a new manufacturer. The part at fault is the ABS module and Hydraulic Control Unit. These parts were replaced while under factory warranty in August of 2020 with 13,894 miles and needs to be replaced again under RAM's extended warranty with 24,000 miles. This is an ongoing issue with these trucks. I keep getting mixed answers if the truck will pass a state inspection with the ABS light on.

First time brake system hydraulic control unit failed was at 17,000 miles, now have 76,000 and it has failed again. Abs system notification goes off and on constantly. Turbo actuator has failed at 76,000 miles. Check engine light and associated ecu codes are flashing. Rear view camera on tailgate goes out intermittently.

ABS/ESC light illuminated on dashboard to service. Truck at 46k miles with pristine service condition. Truck taken within 2 days to Firestone Automotive and code of C0020-01, ABS Pump Motor Controller General Electrical Failure received. Unable to order parts from dealer, national backorder, believed to be Anti-lock Brake System module and Hydraulic Control Unit (HCU). Service department unable to fix, told to drive it or wait until new HCUs are in stock. Unclear if risk to others while driving truck with faulty ABS module and HCU.

The ABS and Traction Control units stopped working with 23,000 miles on the truck which also caused the cruise control to stop working. This is obviously very dangerous to have the brake system fail. Dealer has taken 8 weeks to get the parts and is costing over $2000 to repair. The dealer states they have never had this however there are many forums / videos on the Internet discussing this exact problem. The 2019 to 2022 RAMs already have a recall for this exact problem while the 2017 and 2018 owners have to pay for it out of pocket.

I have a 2018 Ram 2500 with 68000 miles. Last year while driving the ABS and traction control light came on. The sensor will frequently trip and the code will come in and out intermittently. Upon research, it seems this is a known deficiency with this model. I called the dealership and while they agree it is a known issue, there is no recall so I will be forced to put out the money myself. With labor the cost would be over $1600. I am about to spend over $500 for a new Electronic and Hydraulic Control unit for the trucks ABS and just do the repair myself. Is there any relief at this point from the NHTSA? can we finally get a recall issued? I have seen over 212 complaints on this very website for this very topic. This is only the ones that have found this website and made a complaint. How many more dont know to do this?

Started getting Service Brake System and ABS warnings in July 22. Had the ABS module replaced. Still getting alerts which deactivates the cruise control randomly when the warning appears. Warnings ding randomly and frequently. Apparently the hydraulic control unit needs replaced but the part is not available and can't be ordered now. I'm worried that I will lose my brakes.

ABS SERVICE LIGHT CAME ON FOR THE SECOND TIME. I TOOK IT IN TO THE DEALER THEY REPLACED A PART AND NOW ITS BACK ON AND OFF.

Hydraulic Control Unit is failing at 58k miles. Keeps flashing on and off saying check ABS System and Check Electronic Braking System. This is a known issue by the dealer and all over the forums and is a recall on other years just not my specific model currently.

In july 2020 the service electronic braking system and service antilock braking system lights and messages started to randomly appear and go away on the dashboard at around 24,000 miles the dealer changed the abs module and controller under warranty on aug 07 2020. Now at 67000 miles on Feb 01 2023 the same messages are happening with code c0021-01 this will be the second brake control module that is failing that will have to be replaced on this vehicle another guy I work with has experienced the same failure on a 2016 ram 2500 around 30000 miles and we are told parts are on back order

Bought a truck and drove around 420 miles home, within 24 hours of purchase warning lights and sounds went on and off over and over while driving. Took it to 3 mechanic shops, and all 3 said it was the same thing. All shops said it's been a problem for that truck, but there are no recalls on it yet. The warning lights are for the very important ABS brake system and traction control system. Having a hard time finding a mechanic shop that can get the parts to fix the problem.

Code for right rear wheel speed sensor came on. Resulting in no abs,traction control, 4x4,or parking sensors. I bought new part from dealer had mechanic change it. Reflash abs and still on. Went off briefly for 5 seconds came back on. I've realized it's it's common problem. Resulting in the abs module needing replaced. But it's only a temporary fix.

Had the Service Electronic Braking System Light warning activate at around 30k miles. Cycles off and on continuously rendering cruise control inoperative. The dealer diagnosed and replaced a faulty HCU. At 44K miles the problem appeared again with the same indications. Diagnosed as the same cause. Waited a few weeks for parts, now awaiting a service appointment to have issue fixed. Over 3 months now with intermittent ABS operability. RAM's urgency to fix the issue has been extremely dissapointing.

ABS/STABILITY fault happens constantly.

ABS system failed at 6000 miles. Dealership replaced the brake system I was told. AT 37000 miles just out of the basic warranty it has failed again. Dealership can not do the repairs due to the fact there is not enough replacement parts because of all the trucks are failing in this matter. ABS/TRACTION control failure. I have been waiting four months and told maybe March now. Dealership has been in contact and doing everything possible. Its just so many trucks are failing. I am almost ready to sell it at a loss. I purchased this truck to haul my RV which I don't dare too. Also they welded my steering linkage on a recall and now I can not align my steering with new tires. I am just amazed with this repair on a heavy duty four wheel drive as well. They did not inform me on this cheap repair. Something a kid would do and not tell his dad. Also the cruise control is now not working while there is a abs failure. 6000 miles on first failure of brakes. Truck has now 42000 on it. Im afraid of driving this truck anyplace with traffic. This truck will kill someone with this issue.

ABS & Traction Control System lights began flashing intermittently, then remain lit. Loss of ABS system control and cruise control. Dealer in Brookhaven, MS diagnosed faulty HCU as the issue in October 2022. As of 1/31/23, HCU is still on back order, resulting in loss if use of my vehicle for nearly 4 months. I use my truck to support my small business, so hardship is mounting.

ABS and stability control fails and warning lights activate intermittently 11/11/22 (47,290 miles) The cruise control disengaged without notice when the faulty modules light up. Under a heavy load this caused severe speed reduction and momentary loss of vehicle control Reported to dealer.(Rothrock motor sales) It is a know issue with thousands of suspect ram 2500's Parts are not available due to demand. This is an intermittent fault with the Stability control and/or hydraulic control module. Both parts or one part faults the other creating a hazard for all drivers Dealer was made aware of issue and states parts are back ordered months out if at all available causing customers to drive the trucks with unsafe braking due to no other means of transportation This is a well know defect being ignored by Chrysler/Ram

At 36,100 miles I started getting ABS light warning flashing intermittently on my dash. I took it to a mechanic who told me it needed a ABS module and/or a controller device replacement but these parts have been on back order for the last four months (says RAM). It looks as if many, many people are having this same problem with this vehicle. This problem resigns the vehicle as inoperable since it involves a braking component that is obviously a safety issue. This is my only vehicle so I MUST drive it at times which makes me very nervous.

The truck shows a code indicating the ABS Control Module and ABS Hydraulic Control have failed. The warning lights come on intermittently while driving. These warning lights disable the trucks ABS functionality along with traction control and cruise control is disabled while these warning lights are on. This problem is very widespread among this particular model. Enough so that replacement parts are on backorder and there's no guarantee that replacing the parts will remedy the problem as they will replace with the same OEM parts which have failed again in other documented cases. Several dealers I have spoken with can't even repair the issue, because they say they cannot get new parts. Ram should take responsibility to remedy this problem once and for all, as it creates a major safety hazard with the braking functionality of these trucks. This is concerning, especially considering most folks with these trucks use them to tow, creating an even more dangerous scenario in the event of brake failure at highway speeds when towing.

At 67k mileage my 2018 Ram 2500 abs, traction control and electronic braking system warning lights flash intermittently, dealer, auto parts store and several online sites state it is the ABS and HCU modules electrical failure. This causes the abs system to malfunction and poses immediate threat for crash especially while pulling trailers. When the lights flash the cruise control will no engage/disengage. No dealer has these module with no clear indication of availability as of 1/27/2023

Abs system is sending codes, dealer says abs pump and module causing code

-Service antilock brake system -Service Electronic braking system - Cruise control does not work -Alarm bell ringing randomly. ABS and Skid Control warning lights at driver instrument panel cycle on off briefly or extended periods. problem escalated in early 2022 Multiple same dealer interactions actions unsuccessful . Chrysler Cares involved since September 2022. Met with dealer 01/26/2023 “ required part is not available — no estimated date when or even if the part(s) may be available….in the meantime I’m to drive the truck with bell and lights flashing and I’m also to be careful because ABS/antiskid system not working.

ABS brake control module fails. Causes system to lose abs, traction control and cruise control. I have had two units fail in 2 years.

The ABS Hydraulic Unit 68143491AB on my 2018 RAM 2500 Tradesman needs to be replaced. The light/notification came on the week of November 1, 2022 when driving down the road at 50-55 mph and then slowing to make a turn. The truck lost traction and the ABS light came on. Fortunately I was able to brake safely. Of course the problem isn't under warranty and the truck only has 15,000 miles. The antilock brake system isn't working and is unsafe when braking suddenly. The trailer brakes for my 3 horse horse trailer will not work because those brakes are dependent on the ABS system as well. The dealership that I purchased the truck has diagnosed the problem and I have been on a list for the part since November 11, 2022. It was supposed to arrive January 18, 2023 but didn't. Now the dealership says that it will be March 15, 2023. It is a known problem but parts are not available. I haven't been able to drive the truck and still cannot. The estimated repair cost is $1070 when the part arrives. This should be a recall.

Abs on off messing with cruise control. In snow conditions feel it’s a concern. Sometimes the abs work’s most of the time it’s on/off multiple times while driving. For a 2018 truck with only a little over 24,000 miles not happy that at this time the dealership says they have no clue when they will have parts to fix

Beginning at almost exactly 28000 miles, this truck intermittently shows a warning for a fault with the “electronic braking system” and the “antilock braking system” where there are multiple warning lights and tones, and the ABS, traction control and cruise control becomes inoperative. This has increased in frequency and occurs in any conditions at random intervals. Recently it has come on and off as many as 20 times in a 12 mile trip. I am aware of a current NHTSA investigation into these vehicles as well as a class action lawsuit against Stellantis. I have reported the condition to my dealer who advised it is not covered under warranty and no parts are available to repair it.

The trucks ABS light and traction control lights intermittently come on. There is no pattern or reason for this occurrence. When lights are on anti lock brakes, traction control and cruise are disabled. The truck has just over 50K miles and was brought into the dealer for diagnostics. Repair was suggested for the HCU (Hydraulic Control Unit). Was then informed the item is currently on back order and is a well know issue with these trucks. My dealership proceeded to inform me they are currently waiting on "at least 5" of these units for trucks just like this one. This is a major safety concern should hard breaking become necessary and the ABS system isn't functioning properly. To make matters worse it's not even available. I was told they "Hope to have some start shipping out in March of 2023".

My ABS and Traction control has stopped working for the last 5 months. The warning alerts come on and off constantly. I have tried to disconnect the battery and waited an hour then reconnected but made no difference. I contacted the manufacturer and couldn’t get an answer about this wide spread problem. I use this truck for towing my Travel trailer and with this system failure it has my ability to stop safely and without the traction control, pulling the trailer and parking at campsites is dangerous. My truck is available for inspection at anytime.

I had a car pull out in front of me had to hit the brakes hard to avoid hitting him, after that my abs light came on says it is the hydraulic pump motor. I looked it up on line says they have 3 service bulletins on it, if it is a known problem why don’t they recall it? Brakes should be one of the highest priorities for safety on it. The truck only has 33000 miles on it.

This is a known problem with the ABS control module system

C0020-16 code abs modual voltage below threshold. No cruse no ABS and no trailor brakes

Anytime while driving the truck waring lights on the dashboard will come on intermittently. The ABS and traction control light will come on, and on the display screen two different messages will appear along with alarm sound constantly dinging. One message says (Service Electronic Braking System) the other says (Service Antilock Brake System). If driving with the cruise control on when those lights and messages appear the cruise will stop working. This problem is intermittent it comes and goes, but usually very often. The truck is out of warranty with 41000 miles on it and this has been happening since Sept. of 2022. I had it diagnosed by an independent garage and had two trouble codes (C0020-01 ABS Pump Motor Control General Electrical Failure) and (C0020-16 ABS Pump Motor Control Circuit Voltage Below Threshold). The truck still seems to stop normally, but I feel very unsafe driving it. The ABS Hydraulic Control unit is unavailable from the dealer. As of today Jan.-18 2023 they are saying it will not be available until March-15 2023. This is most definitely a safety issue on the truck which should be recalled. The dealer says the parts problem is a supplier issue. I believe the manufacturer knows these are defective and is trying to avoid recall.

While the vehicle was still in warranty ~30k miles, the ABS and traction control lights would flash off and on numerous times as the vehicle was driven. Knocking the cruise control off. The dealership replaced the ABS module and HCU. Less than 20k miles later the issue has come back again. The alarms and lights flash repeatedly every time I drive and traction control along with the cruise control is unavailable. Now the truck is out of warranty, and this is over $1000 to replace. This is a known and well documented issue with Ram and needs to be looked at for a recall. The parts are backordered for 9-12 months. And the replacement does not fix the issue.

I have a 2018 Ram 2500 Diesel and throughout the past 24 months I have been receiving intermittent ABS and Traction Control lights while driving. Recently (3 days ago), the lights have come back, are staying on, and the screen displayed the words "Perform Service". I attached my diagnostic tool and the Code captured is: C0020 Status: MIL/Confirmed - ABS Pump Motor Control - General Electric Failure.

The HCU (hydraulic control unit), at approximately 70k miles, the service ABS light began to illuminate intermittently, after about 300 more road miles it would remain in constantly. At the same time, my ABS system and skid control was forcefully deactivated by the vehicle. Currently, I cannot use the full breaking capability of the vehicle or stabilization control. This vehicle is available for inspection. The problem is still present. My safety is greatly at risk when towing large loads. It is at risk during inclement weather where ABS is very important in maintaining traction. This problem has been confirmed and documented at the dealer. There was no prior warning before failure.

- I have a repeated low mileage failure of the antilock brake system hydraulic control unit. The faulty unit is still installed on the vehicle. - The ABS hydraulic unit failure intermittently renders the ABS system, traction control system, and electronic stability system inoperable for varying durations. This is the 2nd failure of this system on the vehicle. The first failure occurred during normal highway driving. The 2nd failure occurred while traveling in the mountains in the snow. Had I not been experienced driving a non-abs vehicle in inclement weather we could have crashed. - The issue was diagnosed and confirmed by a local Ram dealership service department. It was escalated to Ram customer care due to lack of parts availability and high cost of repair. Ram escalated part delivery and denied financial assistance. The vehicle is out of warranty for this particular part. - There are various intermittent warnings present. The fault condition will rapidly annunciate and then clear many times in a short time period, or stay active for long periods, or not occur at all. The fault condition appears to be completely unpredictable but is repeatable.

Intermittent warning on dash and chime with "Service Electronic Brake System" and "Service Antilock Brake System". On most daily drives the chime and warning go off about every 2-4 minutes. I have video of it going off 30 times in one minute. Dealer wants to replace brake controller and head unit at a cost of $1600. This is a safety issue and should be recalled.

abs brake light comes on intermittently taking off my ABS brakes and anti skid

2018 Ram 2500 with 18,900 miles. While driving at various speeds, the ABS and traction control warning lights illuminated with an audible chime. The brakes would slip upon depression of the brake pedal while the warning lights are illuminated. ABS control module/traction control is intermittently failing. There is no antilock braking or traction control on wet/icy conditions.

My truck at 38,000 miles started flashing occasionally ABS and traction control warning lights. Neither my ABS or traction control are working when the lights are on. Now I have 45,000 miles on my truck and both lights are on all the time I had the code read and it is C0020-1. My understanding is this is a known problem and my cost is over $1000.00 to fix this problem. I contacted my dealer and they told me my truck is out of warranty and they don’t know of any recalls or investigations into 2018 Ram 2500 braking systems. I have not gotten the issue fixed and we drive it as little as possible. The truck is available for inspection. I am not willing to pay the dealer to inspect the truck.

•ABS control module/traction control is intermittently failing •no antilock braking or traction on wet/icy conditions •yes, both dealer and a second opinion garage have both diagnosed the problem •only the garage mechanic inspected the failing part •vehicle warning lights come on when part is failing

The antilock brake system has failed. The vehicle is available for inspection. Without the antilock brakes operating properly, the vehicle is harder to control in emergency situations or on slippery surfaces, endangering the safety of myself and others. The problem has been confirmed by an independent service center. ABS and traction control lights are on. Service ABS Brake System message on dash. ABS and cruise control inoperative. Code C0020-01 present. Symptoms first appeared May 17 2022.

At approximately 104,000 miles beginning last September I started intermittently receiving a warning service abs brake system and traction control. It would be more frequent when going down a bumpy road. It continued for a long time and gradually became more constant. Internet searches had suggested fixes of removing the fuse for the abs system, in and of its self creating another safety problem. Ram has issued a bulletin for its mechanics telling them to change the ABS control, so obviously this happens a lot. The invoice for the repair is a attached which says there was an internal short on the abs pump. I note that beginning in 2019 Rams there is recall for a faulty abs pump. Obviously the pump on my truck is also faulty and should be replaced a Ram's cost by a recall. I will attach the invoice if there is a place to do so in this form. Lots of complaints about this issue can be found on line. Some examples are at: https://m.carcomplaints.com/Ram/2500/2018/brakes/service_brakes.shtml and https://www.ramforum.com/threads/2018-ram-4x4-diesel-service-anti-lock-brake-system.153111/page-4

Truck was bought by me 12/28/22 with around 4900 miles on it. Within driving the vehicle approximately 40 miles the service electronic brakes and service abs lights began to illuminate intermittently. I have driven approximately 2000 miles and they keep going on and off, seemingly while hitting bumps. From my research I believe it to be a failure of the abs hydraulic control unit. I believe the manufacturer knows this to be a common problem and has revised the part in question. This should be a recall on these particular trucks, a quick Google search of the part number of the hcu will reveal numerous people with the exact same issue.

Abs and traction control lights come on and off dealership replaced the hcu and the problem stopped. 2 years later and only 3,000 problem started again. Contacted the dealership and they said its a known issue but no parts are available and no recall

C0020-01 code began coming in and out immediatly following a service at my local Ram dealer. I returned to the dealer after the warning lamps and messages all came in around ten times within a mile of picking my truck up from them. The dealer used a device to clear the messages, but the alarms returned again after I left. There are multiple warning lamps and messages that remain in as a result of this: service anti-lock braking system, ABS warning lamp, traction control lamp, and a loss of cruise control functionality. While the constant "dinging" sound and loss of cruise control on a truck with less than 20K miles is disappointing, I am concerned whether or not these warnings are indication of a serious safety hazard to my family and/or those we are on the highway with. My truck is available for inspection. The issue was confirmed by my local dealer who cleared the alarms when they first came in.

The ABS module and associated control unit have failed. This causes the anti lock braking and traction control systems to be inoperable which can cause the vehicle to lose control which can cause injury or death. FCA is aware that these units are defective and refuses to fix them.

Traction Control Light is illuminated, Service Trailer Braking System, and Service Trailer Brake System Notifications are present on engine startup. ABS system appears to be inoperative in slippery conditions. Service Engine Light comes on every 15 miles or so with Codes P0572 and P0572pd. Download codes and they go away.

inconsistent flickering/flashing of the "service electronic brake system" & "traction control unavailable" lights with audibles dings. Additionally, the ABS light illuminates. After research this appears to be a common failure point that costs over $1,000. My truck is a 2018 with 36,000 miles. I do not know if my brake system will fail on me or what. I haul a 12,000 lb trailer with horses and rely heavily on my ABS system working in case of emergency. I'm submitting this claim because I know there is an open investigation by the NHTSA and would like to add on to the complaints.

Slightly out of warranty. Suddenly starting getting ABS warning light coming on and warning chime then it goes out and shortly thereafter comes on again, it doesn't quit for many miles. Take to dealer and find out its a failed ABS module and HCU. Also find out through repair history that the ABS module had been replaced at about 14000 miles so this was a second failure. Found out through online sources that there are many failures of these items on but it is mostly on the 2018 vehicles

Multiple failures on ABS Brake control module. Module has failed twice now within 30,000 miles. Manufacturer has no urgency in prdocing replacement parts. Cannot drive vehicle due to this issue.

ABS system failed to perform. Hard braking on interstate caused tires to lock up and vehicle began to slide, causing trailer to start to outrun truck. A message appeared stating that ABS system needed service. The message is not stored in the message center so I can not confirm wording. Dealership replaced a brake component due to finding a problem buried in the computer at 39993 miles. This event occurred at approximately 45000 miles as the truck now sits with 45057 miles. Appointment has been made with dealership which states that diagnostic fees may be charged.

ABS and Traction control lights on together, took into ram service dept which indicated internal fault with ABS pump (hydraulic control unit) need to replace and bleed brakes to correct. Not possible to order needed ABS pump replacement until at least 2 months away, advised not to use vehicle especially for towing as unsafe in this condition.

ABS and traction control light are coming on and going off intermittently, when it comes in shuts off cruise and could lead to a rear end hit, after searching for ABS issues seen Ram was recalling a lot of vehicles for an ABS issues, was wondering why the 18 year was not included?

Flashing abs and traction control no cruise control Code C0020-02

Abs, stability control and cruise control are not working as they should. Dash is constantly displaying a warning error about the brakes and stability control.

During the month of July 2021 I would get a message to service the antilock brakes. At 16400 miles I took the truck to the dealer any they replaced the Control Anti-lock brake system and Module. Part numbers 68143491AA & 68347098AB. As of this week with 24400 miles on the truck I am getting the same intermittent message. The the message comes up with shuts down cruise control, makes a chime noise and turns on dash lights. The message will come up stopped to moving at any speed.

Anti lock brakes are on and no towing brakes. Replaced hydraulic control unit and ABS control module. Message showing service anti lock and ABS. Dash continually ding to service. Unable to reset.

Service electronic brake/ service ABS warning lights come on intermittently causing cruise control to disengage. This is the second time this issue has arose. The first time the dealer replaced the HCU. This is a common problem and needs to be addressed and a recall initiated. The parts seem to be defective because this problems continually occurs.

ABS module failure, part has been on back order over 2 months, was told by 2 dealers this is a common problem and to limit driving, this problem also affects the towing features and will not allow the trailer brakes to activate.

ABS and Traction Control warning lights flash on and off constantly and there is a warning tone that beeps non-stop on my 2018 Ram 2500. When these warnings appear, the ABS System and the Traction Control are disabled along with the cruise control. This has happened twice already, and my truck only has 4000 miles on it. The first time was in October 2021 when the truck had under 3000 miles on it. The dealership replaced the ABS pump which fixed the problem temporarily. In August 2022 the same problem appeared, and the same warning lights came on. At this time the truck had around 4000 miles on it. I took the truck in for service in October 2022 and even though the truck was out of warranty, I still had an extended warranty contract. This time I was told it was the ABS Control Module and that the part was on backorder for 3 months or more and that since they could not get the part I was not covered by the extended warranty and was charged a $175.00 diagnostic fee, but that if they were able to get the part that I would have been covered by the warranty. All the dealership was able to do was reset the code which lasted for about 20 minutes before the problem started again. It is now December 28, 2022, and I have had to drive around for the last 6 months with the dashboard flashing and the truck constantly beeping and with the ABS, Traction Control and Cruise Control disabled. I have seen hundreds of complaints regarding the same problem and yet Dodge has not issued a recall regarding this issue. It's beyond comprehension that my truck has had the same problem twice and it only has 4000 miles on it and now Dodge is telling everybody that the part is not available until next year, and so everybody that has this same problem has to drive their truck around with flashing warning lights on the dashboard and a constant dinging tone which gets very distracting and annoying, and on top of that their ABS and Traction Control is disabled. This was my first and last Dodge.

At 50k miles the ABS/Traction control lights illuminate on and off, cruise does not function as well. The code states ABS pump and/or electronic controller. The dealership is replacing both and updating software for $1600. Researching the HD Ram forums I found this is extremely common for 2017 and 2018 models. NHTSA as of November 2022 is investigating.

Sporadic light warnings displayed on dashboard along with warnings of Traction control and Service ABS control module. C0020-01 code pulled with code reader. Dealership diagnosed that ABS Pump motor control failure and replacement was needed. Parts on recall until earliest Jan 2023.

I have the dreaded Ram 2500 ABS/HCU issue. Light constantly coming on/off, appears to hinder the abs from working, very noticeable when towing the boat in the rain.

Service ABS and traction control warnings go on and off, on and off, on and off etc to the point where the vehicle isn’t drivable. The truck has only 14k miles and is out of warranty. Took it to the dealer, they said it is a known issue and that the ABS hydraulic control unit needs replacing but it is on back order until at least January of 2023. So now I have a $60k truck that is not safe to drive and can’t even get it fixed.

My hydraulic control unit for my abs system is malfunctioning and allows my brakes to lock up with very little brake pressure applied. The faulty abs/hcu module is a known problem with Chrysler and they refuse to issue a voluntary safety recall and replace the parts. There are also no reputable sources of a replacement part so I am unable to perform the necessary repairs on my own. The module also triggers a repeated loud auditory and visual alert continuously when operating the vehicle that is incredibly distracting to the driver and contributes to an additional unsafe environment for operating the vehicle. Additionally the faulty module also periodically kicks off cruise control uncommitted adding to the unsafe nature of the fault, especially when driving at highway speeds.

while driving the vehicle beeps several times indicating that there is an issue with the ABS, also notice the traction control and ABS was lite up on the indicator panel. i was on the highway and before i could find a safe place to pull over both the beeping and the illumination cleared. several days later it showed up again and disappeared just as fast. this issue just happen, so i'm doing some research to see if there are any recalls.

DIAGNOSTIC CODE: C0020-01-ABS PUMP MOTOR CONTROL - The ABS and Traction Control warning lamps illuminate intermittently as well as a message to "Service Electronic Braking System" and "Service Antilock Brake System". - Issue started in Oct 2022 with 33,570 miles. Truck is out of time period warranty and was denied by dealership. Research online shows this is a common problem on this vehicle. Additionally, the replacement parts are not available to order from any dealership as they state that FCA/Stellantis are not accepting orders for the replacement parts.

In July 2022, the esc/abs dash lights as well as the ‘service electronic brake/service ABS’ warning began intermittently flashing with resultant loss of traction control and ABS including cruise control. It would continue to activate/deactivate numerous times over the next couple of months. The dealer has identified the hydraulic control module as defective requiring complete replacement of the HCU and ABS system. Online search shows this to be a common known problem along with well over 100 complaints filed with the NHTSA regarding model years 2017-2018. Interestingly, there is a recall for this very problem for the same truck series years 2019-2022 for the same part. There are over 2500 orders for this part and my dealer is not allowed to place an order until mid February because of the backlog endangering my life to use my only vehicle that can be used in the snow this winter. Dodge is clearly not supporting its customer base with providing a known defective part replacement in a reasonable time frame forcing those that don’t have an alternative vehicle to risk their lives and those on the road around them by driving a 7000 pound vehicle that can lose control and not be able to stop given that we are now in the middle of winter.

Abs and traction control warning lights sporadically illuminate. "Service hydraulic braking system" and "service abs system" warnings. Loss of antilock brakes while hauling trailers etc.. Problem began around 38000 miles. . Loss of abs braking system is a concern..

diagnostic code c0020-01 abs pump motor control. lights on in vehicle. appears to be major problem with this vehicle. dealer could not confirm if this could be repaired under warranty. unable to get parts to correct problem.

The ABS and Traction control lights illuminated and have received messages of "service electronic brake system" and "Service ABS system". When the vehicle was inspected at the local Dodge dealer I was told it was out of warranty and it would cost over $1800.00 to replace the ABS module and Hydraulic control unit. I have searched and have found that this is a widespread issue and people are wondering why a recall has not been issued. I have no choice but to pay out of pocket for this repair as I live in a snowy area and travel with a 2 year old and my wife. I of course do not want to use the vehicle in bad weather without ABS and traction control. Therefore my "new" to me truck sits more than I drive it as parts are on backorder. Considering how widespread this is I have to imagine that there should be a recall.

At only 51k miles the ABS pump has quit. They want 900+ to replace it and I know several other owners with the same issue. I’ve never had an abs pump quit on a vehicle before

Service electronic brake system and service antilock brake system comes on intermittently which disables traction , cruise and antilock brake control systems when it happens, very dangerous in slippery weather

The ABS light will go on and off the dash over and over. The truck is 134 miles out of warranty and the dealer said the parts are the ABS pump and electrical board went bad. They do not have the parts to fix then and it is not warrantied now. This is a well known problem and there is plenty of knowledge at the dealers of the issues. They knew what was wrong without even driving the truck. The pump going bad at 36, 239 miles on my truck should not happen. They already have an updated fix but will not admit they sold trucks with a faulty ABS design and should be fixing these trucks for free. My ABS no longer works and I have no cruise control or traction assist and I live in the snow belt of Ohio. I no longer feel safe driving my 4 daughters around in my truck I am still paying for, it is not comfortable knowing a massive company like Ram is doing nothing about it.

there seems to be many problems with anti-lock brake issues in the ram trucks. My truck has never been in salt or snow and has always been stored in a garage, it has less than 20000 miles on it and has started the default code. I have seen a lot of truck reports with less miles than mine with the same problems. Ram should be made to repair this problem for safety sake.

The “Service Electronic Brake System” and “Service Antilock Brake System” messages with associated lights and audio appear intermittently and frequently. This condition happens somewhat randomly regardless of speed or road conditions. This issue will also cause the cruise control to shut off. After taking the truck to the dealer and running a diagnostic, the technician claims it is the ABS pump and Hydraulic Control Unit. The technician said it is a known issue and the parts are back ordered.

ABS light and traction control lights came on. I had to replace ABS controller and hydraulic control module. Truck had 37000 miles on it and it was just out of warranty by a little over a 1000 miles

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds, the ABS and Traction Control System warning lights started flashing. Additionally, messages to service ABS and electronic braking system were flashing on the instrument panel. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the ABS control module and the hydraulic control module needed to be replaced. The vehicle had not been repaired. The failure was intermittent but had since become constant. The manufacturer was not made aware of the failure. The approximate failure mileage was 65,000.

Mileage: 65,000

Lost braking power. Anti-Lock brakes quit working. Lost cruise control. Unable to use anti-lock brakes. Brakes locked when stopping. Flashing dash alarm saying service ABS/Electronic Braking System. All occurring without reason, just randomly. This puts my safety and the safety of others at risk as the brakes lock up when depressed at times as well as loss of braking power.

The anti lock brake system frequently turns off and activates warning lights for it. Since the truck is used to pull loaded trailers I feel this is a safety issue since you can not depend on the brake system to function as abs or it suddenly fails and goes to manual only. Repair facility said code calls for the abs pump to be replaced but the part isn't available due to a back order of almost 800 units as of November 2022.

I saw article that the 2018 Ram 2500 trucks are under investigation for poor brakes. That was the 1st thing I noticed on my truck. I had a 2010 Dodge Ram the same model and had better brakes. My wife was driving it at the speed limit and the light turned yellow and by the time it stopped she was in the middle of the intersection. The truck stops better when pulling our 11,000 lb RV only because the trailer is doing the stopping. I usually drive the truck and I have to be very aware of my following distance because it just doesn’t stop like I feel it should. We mostly use the truck for camping and only have about 26K miles on it. I agree the truck is heavy, but it should still have adequate brakes.

My ABS and HCU are throwing codes and my local RAM dealership says this is a common issue. I went in October 2022 and they said at that time parts weren't coming in until February 2023. I called today and they can't say a date. I've read mainly articles online and this seems common. My truck is a 2018 and just went over 50,000 miles when this started occurring. My dealership won't state if this is covered under warranty, I believe this should be under drivetrain. Feel free to call me [XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I found there is an investigation going on with 2017/2018 year trucks of my model. Early 2019 my truck threw warning lights that my brakes were out while I was driving. Testing them they seemed to work alright still but manage to get it to the dealer. At the dealer they replaced the HCU and sense then I haven't had any issues. The truck was s under warranty so I didn't pay anything out of pocket.

Brakes seem to be intermittent. Check Electric Brake warning comes on every time you start the truck and has shutdown the ABS and cruise control options. This is a very big problem if you research it on the internet on Ram and Mopar forums.

Have 52000 miles on 2018 ram 2500 when the "Check Electronic brake System " appeared on dash and ABS became inoperable. Went to dealer and was told i needed to change Hydraulic Control Unit and it was on back order until Jan 23rd 2023. was Told that instead of a Proportioning valve for the rear the HCU controls Brake pressure to rear brakes and with it inoperable the Rear brakes have a potential to lock up quicker when braking so i have parked the vehicle. symptoms occured about 800 miles ago.

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds and towing a trailer, the ABS warning light illuminated. The vehicle failed to stop immediately with an extended braking distance while the brake pedal was depressed. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The contact stated that the failure occurred only while towing a trailer. The contact stated that another time the trailer brakes overheated while braking system on the vehicle failed. The manufacturer was not notified of the failure. The failure mileage was approximately 90,000.

Mileage: 90,000

The contact owns a 2018 Ram 2500. The contact stated that while driving approximately 65 MPH, the braking system malfunctioned causing the brake pedal to extend to the floorboard while depressed, and the vehicle would not immediately stop. During the failure, the parking brake was used to slow the vehicle. The vehicle was towed to the local dealer who diagnosed that the brake line had failed causing brake fluid to leak from the vehicle. The brake line was replaced, and the vehicle was fixed. In addition, later while driving, the ABS warning light was blinking off and on. The dealer diagnosed that the ABS module was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was 58,000.

Mileage: 58,000

Rear Anti lock brake system light came on along with the traction control light at the same time. Quick google search and I found that this is a known issue with this truck and is being evaluated for a recall. I would like to know if this is in fact a known issue that the manufacturer is aware of and if there is any relief for repair from the manufacturer as well.

Service electronic braking system light and service abs system.

Received warning of ABS and ESB malfunction as noted in the recent investigation PE22012. This malfunction occured while driving in rain and poor weather conditions, increasing the risk of safety of occupants. Warning indicators appeared and have appeared in the days and weeks since first occurrence but are not always on. Awaiting appointment for inspection at dealer service center.

experiencing intermittent loss of breaking performance. Peddle will go to the floor, and front brakes wont work. Rear brakes seem ok.

Was driving on expressway exit ramp trying to come to a stop and the brakes hesitated and then locked up, at the same time the traction control and abs light came on. Traction control and abs lights still come on months later and problems with breaking are still there. Took to local shop to get fixed and they told me abs module and hcu pump are bad. Parts are not available thru mopar or aftermarket.

ABS break failure and deactivating of cruise control on interstate. No warning when it may happen. Does it multiple times a trip.

Intermittent failure of the electronic braking system. Audible Warning tone and indication "Service Electronic Braking System" followed by "Service antilock braking system" experienced intermittently. The multiple warnings automatically disabled the antilock brakes, stability control, and cruise control as well as producing annoying audible tone. This failure originally began occurring in August 2020 and was taken to the local Ram dealer in September 2020 when it was diagnosed as a defective 68143491aa hydraulic control unit module. After a three week lead time, the module was replaced under warranty with 12116 miles on the vehicle and the problem disappeared. Two years later in July 2022, the same warnings began intermittently with the same disabling safety issues at 24000 miles. On 10/19/2022, the Ram dealer diagnosed the problem as "Abs Control Module 68143491aa Has Internal Short. Part Is On Backorder With No Eta". I have repeatedly checked on the status of the part with the Ram dealer resulting in the same "Backorder with No ETA" response. In November 2022, I filed a formal complaint with Ram Cares. They have provided the same response "Unplanned resource requirement resulting in supply disruption. No firm ETA to provide at this time. Working to improve". This failure is a safety issue, not just an inconvenience and annoyance. My Ram 2500 is periodically used to haul a 10000lb trailer. The sudden loss of cruise control, stability control , and antilock brakes could cause and accident resulting in property damage and injury or death.

1. ABS Module and ABS Pump have malfunctioned, parts have been backordered for months with no ETA. 2. The problem has been verified by an independent service center 3. Has not been inspected by anyone else. 4. ABS light and Traction Control light come on intermittently.

ABS system malfunctioning, “service electronic braking system” and “service abs” messages flashing continuously while driving. Known issue among Ram. Was quoted $1000 to repair ABS module.

ABS system failure. Dealer informed me that brake fluid leaked through manifold into the computer module causing ABS system failure. Warning light on dashboard says ABS traction control warning, electric braking system warning.

ABS/traction control intermittently disables Without ABS/traction control while in poor weather conditions it creates a potential for an accident Dealer told me I need a new hydraulic control unit Service ABS and service electronic braking system flash and traction control turns off

The ABS pump motor control unit failed. Part number 68143491-AA making the ABS safety feature unusable. This is a know and common problem with this vehicle.

Service electronic brake system indicator came on while driving vehicle. Warning continued to go on and off numerous times randomly and still continues to do so. Took it to dealership to have problem addressed and service worker said this was his sixth 2018 Ram 2500/3500 in his dealership to have the HYDRAULIC CONTROL UNIT and ANTI LOCK BRAKE module to malfunction. FCA should have a recall on this, but as of now they don't. Parts are back ordered and won't be in for months. Dealership told me it's fine to drive as is but I'd rather not take my chances. Please address this. Thank you very much.

The ABS on my vehicle malfunctioned and the warning lights appeared on about 8/1/2022. The mechanic pulled the error code C0020-01 ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. His research indicates the solution is to replace both the ABS Control Module and the ABS Hydraulic Control Unit at the same time. As replacing one without the other seems to lead to additional unnecessary and costly repairs to the same part. After contacting every Ram dealer in my area, there are no ABS Control Modules available anywhere. I then checked the internet and it appears that the ABS CM (part# 68347098AB) is not available anywhere with over 2500 on backorder at a single RAM dealership in Texas. It appears that there are many thousands of RAM owners with the same problem and the lack of a replacement part is troubling. The ABS system in vehicles is a BASIC safety feature and a malfuctioning ABS will undoubable lead to crashes and possibly deaths. As a owner of an affected vehicle, I request that you investigate this problem and force RAM to ensure that their vehicles are equipped with the basic safety features that are required by law.

While traveling down a road in Palatka, FL, going 70mph, I experienced my truck disengage from cruise control and violently lock up the rear tires during wet road conditions. Shortly after the cruise control disengaged, an intermittent ABS and Traction control light illuminated. After bringing my vehicle to a certified auto shop, I was informed that the ABS Pump (Hydraulic Control Unit) OEM Part# 68143491AB was found to be at fault. I was told that the part would not be available until January 18th, 2023. After completing some research online, I found numerous people have reported the same problem I was having and also dealing with part delays. The Anti-Lock-Brake and traction control systems are both integral to the safe operation of the vehicle. Without the systems functioning properly I put my life and others at risk. I hope this issue gets looked at seriously and can be resolved promptly. People's lives are at stake.

abs module failure replaced on 21 Nov. 2021. abs module failure second time back in for replacement on 21 Nv. 2022.

HCU failing. Blinks on display screen. Appears then disappears. When in cruise control and the HCU goes haywire, kicks cruise control off unexpectedly. When this occurs and the driver isn't expecting it, this causes panic because the vehicle rapidly slows down, nearly causing a vehicle collision if not prepared for it. I was almost rear ended due to this. Research on this failure would reveal this issue to be affecting 1000's of 2018 RAM trucks to have this problem. My local Dodge dealer advised I am approximately the 2500th person waiting on the part which is currently on BACKORDER. Have been a Police Officer for 15 years, safe driver and this nearly caused an accident on 695 Baltimore County, MD during heavy traffic.

HCU is malfunctioning. Loss of ABS. This has been checked at a certified dealership. Warning lights come off and on. This has been happening for the past 5 months. The parts are not available. Dodge/Ram need to make these parts available or they need to give us all a new vehicle.

I received a message regarding ABS failure. I had it checked an the OBD and it showed an active C0020-01 code. This is a widespread problem with this vehicle. So much so that FCA issued a bulletin dated 4/28/20, case # S2005000004. Parts are not available. The manufacturer should be held responsible for selling a clearly deficient product. Inoperative ABS is a serious safety issue and should be corrected immediately.

The truck ABS, traction control, and service electric brake lights and warnings have flashed and beeped on and off and on and off every few seconds. I took the truck to the dealer to be fixed under warranty. The dealer states it has a bad HCU and no longer has anti lock brakes however I can still drive the truck with all that distraction going on in the dash. The part is on back order and I won’t have my truck repaired until February (2.5 months) This same part was also replaced a a little over year ago under warranty along with Abs sensors and wire harnesses. I have 2 friends with the same year trucks who also had to have the same repair done. Upon looking up information on the internet it seems like this has been a on going issue on the 4th generation ram trucks 1500-3500 models from 2012-2018 I feel the safety of this could cause a car accident by the distraction of the dash going nuts and the possibility of a vehicle skid while not having anti lock brakes properly working. I would hate to drive it putting my life as well as others drivers and passengers lives in the line due to this safety issue ram is having. The issue happens randomly some times non stop while driving and sometimes I can drive 15 miles or so with nothing then it will start again. It first happened when I had approximately 50,000 miles on the truck and has done it again at 73,500 miles. When the lights are on it will not allow cruise control to work or 4x4 to engage. I have not noticed anything else not working properly.

Anti-lock brakes system warning light comes on intermittently. When this warning light comes on it will also cause cruise control to disengage (if engaged). There is no warning when this will occur. Not sure if the anti-lock brakes are working properly. Dealer has confirmed the Hydraulic control unit and the ABS module is faulty and needs replace.

As I drive the vehicle, the dashboard makes a "ding" sound and the anti-lock brakes and the traction control lights come on. The display reads "Service Anti-lock Brakes". This also causes the cruise control to disengage. The cruise control cannot be set while the two lights are on on the dash. Sometimes the lights stay on for a while. At other times, the lights cycle on and off (and the ding sounds) every few seconds.

My truck was diagnosed with a faulty ABS pump assembly by a reputable repair shop . I understand by looking on the Web, that this is a common with this year and model truck. The dealer/manufacturer has no safety recall for this problem. As you know, the ABS helps the vehicle steer properly in an emergency braking situation by restoring traction to the tires. Loosing traction will shorten the stopping distance or lose control of the vehicle. In view of this, I do not understand why this component is not considered a safety issue. I would appreciate If your agency can assists me in resolving this issue with the dealer/manufacturer. Thank you, [XXX].

The ABS control module has begun failing sporadically while the vehicle is running. When this happens is disables the traction control system and the ABS system until the alarm clears, and if the vehicles cruise control is on, it immediately disengages. All of these symptoms deteriorate the safety margin of the vehicle, and cause mid-driving malfunctions that can be unpredictable. When the module is malfunctions both the ABS warning light and TCS warning light are illuminated and a text warning is displayed on the multifunction display of the gauge cluster. The contact found that the parts to rectify this issue are being rationed by Stellantis, leading to unacceptable lead times in simply procuring the parts. When added to the shop rates charged to fix this issue, the price of replacing this clearly defective component begins to total in the thousands of dollars. Therefore, in order to continue his profession and responsibly take care of my liabilities, operating a four-ton vehicle with a compromised braking system and have done so for two years now. In addition, the ABS Malfunction Indicator chimes repeatedly while driving, creating an endlessly distracting environment.

Abs service brake system light continually goes on and off with a chime each time. Sometimes 20 times in a minute. Code is C0020-01 abs pump motor control general electrical failure. Truck brakes will engage without input.

Our Indicator warning light ABS light was coming on back in May 2022...ABS and traction control lights were coming on. We took the truck to the dealership and paid $223.58 for a diagnosis. The part wasn't covered under our power train warranty, so the warranty department did a goodwill payment for the repair. We had to wait approx 2 months for them to get the part in as there were so many other people waiting for it (I was told about 1100). they did the work finally in July, they said it was fixed. At that time we had 17,730 miles on it.... When we left the dealership the light started to come back on. I tried to reach the warranty dept at Dodge but they didn't return my phone calls. We took it back into the dealership and told them it wasn't fixed and the light is still coming on. We were charged another $223.58 diagnosis fee. They then said that the ABS control unit and module need replaced and the system flushed at a cost of $1993.70. I called the dodge warranty dept and explained my situation. They escalated my complaint and denied us any help. I complained to the dodge dealer that the truck was misdiagnosed the first time we brought it in, and they claim it is a different issue with the same part.....but yet the same symptom. I know that Dodge knows there is an issue with this and should issue a recall.

The ABS system fails to operate when braking causing skidding and loss of control under hard braking/wet/ slick conditions. The ABS light and the Traction Control light are illuminated and warning dings when the abs system malfunctions. This is incredibly dangerous to a vehicle that can tow a combined G.V.W.R of 24K Lbs. The Dealers are aware of the problem and the manufacturer states that they know of the issue but are not being forced to or have any knowledge of a recall for this failure. There are several forums about this and even had Chrysler/Fiat/Ram truck care involved in the forums about the issue but declines any issue for safety and to keep driving it or bring it in to have repaired at the owner's expense. I feel this is a safety issue with the braking system and needs to be forced on the company to remedy the issues at their expense. I work for Daimler Trucks North America and if this was an issue with a Tractor/Trailer, then it would be a recall to be repaired. People's lives are in danger when you have a heavy vehicle that does not have the proper braking safety features working as they are required to install per your standards. If you require it, it should be operational for the safety of all people on the road.

ABS warning light comes on and chimes randomly. Message: “Service anti-lock braking system”. When driving, warning lights come on, chimes sound continuously, and if using cruise control, it is deactivated. Per my mechanic, I need to replace my ABS module and pump. Parts are on national back order. Estimated time for part availability is one and a half years! Truck only had 16,000 miles on odometer when this problem started. Chime warning comes on randomly and sometimes stays on indefinitely. Driving when the chime is sounding is a nightmare. Deactivation of cruise control is frustrating. Loss of ABS in rainy or slick conditions is dangerous, especially when towing 5th wheel. Dodge has no vehicle recalls on the 2018 2500s. Problem is exasperating and dangerous.

ABS Module & Hydraulic control unit

Getting code C0020-01, ABS pump motor control - general electrical failure This item failed within 24 months of purchase and now the replacement is giving me the same failure. Quick web search showing a large amount of there’s issues which controls ABS as well as the traction control system. I understand there’s wearable parts but this should happen twice on a 4 year old vehicle with 50k miles, not to mention the others on the road. This should be a recall item given the frequency of failure

ABS Module and HCU bad with 40K miles, a WELL KNOWN ram issue that they continue to ignore and take thousands of Additional dollars out of consumers pockets as they seem to go bad JUST after the basic warranty expires. 70 thousand dollar truck that is garbage, and Ram won’t remedy this problem. Second power wagon I’ve owned, same issue, similar mileage.

anti- lock brake trouble light is on permanently. Checked with dealer Part number 68347098AB antilock module is on back order. All online retailers are out of stock and no ETA of when its going to be restocked. This is a known problem with Dodge Trucks, without anti-lock brakes the brakes can lock up and skid out of control killing the driver/passenger and anybody else involved. once the light comes on cruise control is locked out. I think this warrants a safety recall. If it was just 1 or 2 cases I could see it being a random problem but reading on all the people who have the same problem, its scary to know as many Dodge ram trucks on the road with possibly no anti-lock brakes what could happen in an emergency

ABS and HCU module failure on a vehicle with less than 50,000 miles on it following all maintenance intervals and instructions. Results in traction control and automatic emergency braking not working as intended. Parts are backordered until January at the earliest, and will be over $1k after labor.

While driving, a warning message appeared "service electric brake system". Taken to dealer. "Found, hydraulic control unit to be faulty." Need to replace unit. Correction determined "ABS SYSTEM ANDSTABILITY CONTROL SYSTEM IS COMPROMISED. SUGGEST NOT DRIVING THIS VEHICLE UNTIL PARTS ARE AVAILABLE AND INSTALLED IN THE VEHICLE. " I was informed by the dealer the party's are restricted and cannot be ordered until January 2023 and then there is no guarantee they will be shipped. I contacted Ram service and was informed the parts did not exist and needed to be manufactured. I inquired how this could happen with only 28411 miles (less when detected) and if there was a recall. I was shocked a safety part like this that prevents the vehicle from being driven was not covered under recall. There was no offer to assist with providing transportation for me while I await for repair.

Vehicle showing error code C0020-01 which is an issue with the ABS system. This is a known issue among the 2018 Ram Trucks which after searching repair options seems to be happening more frequently than it should. This is a major safety issue that is effecting thousands of vehicles and should be addressed. Repairs require a replacement of the ABS Module and the HCU. The manufacturer should be required to fix this safety issue.

"Service Electronic Braking System" and "Service ABS System" lights are flashing intermittently and the "ABS" and "Traction Control" lights are on as well. No diminished braking has occurred yet, however the ABS and traction control become disabled when the issue is present. I am currently opening a STAR case with RAM and attempting to schedule a dealer appointment. The issue started at 43,500 miles. This problem appears to be widespread on 2018 RAM 2500/3500 trucks and represents a safety issue, as the braking and traction control mechanisms are disabled when the issue is present.

WHILE OPERATING VEHICLE THE ABS AND TRACTION CONTROL LIGHTS WOULD FLASH ON AND OFF AND MESSAGE SERVICE ANTI LOCK BRAKE SYSTEM. THEN SERVICE ELECTRIC BRAKE SYSTEM WOULD FLASH IN MESSAGE CENTER. AFTER FLASHING ON AND OFF MULTIPLE TIMES THE MESSAGES SELF CLEARED AND LIGHTS WENT OUT. EACH TIME HITTING A BUMP THE LIGHT WOULD COME BACK ON, THEN WHEN HIT ANOTHER BUMP LIGHT WOULD GO OUT.

The contact owns a 2018 Ram 2500. The contact stated that while operating the vehicle, the “Service Electronic Braking System" and the Traction Control icon were illuminated. During the failure the cruise control would independently be deactivated. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure but no assistance was offered. The failure mileage was 9,000. The consumer stated when the vehicle is started and placed into gear, "Service Electronic Braking System, Traction Control, and Anti Lock Icons" all illuminate. The manufacturer stated the vehicle is out of warranty and if fixed it will be at the owner's expense.

Mileage: 9,000

Service Electronic Braking System and Service ABS system lights are flashing intermittently and the ABS and traction control lights are on. Dealer has indicated the hydraulic control unit is bad and needs replaced but they no longer manufacture that part and there are no aftermarket offerings so vehicle cannot be repaired until parts are located. In the meantime these vehicles affected have no anti-lock brakes and the cruise control randomly shuts off if the ABS light flashes while cruise is enabled.

ABS hydraulic assembly fails intermittently and randomly during driving causing the warning chime to sound repeatedly and results in distracted driving as well as degraded braking safety feature.

ABS Hydraulic Control Unit and Electronic Control Unit Failure. ABS MIL and Traction MIL began turning ON and OFF intermittently during daily driving, sometimes turning ON and OFF over 50 times during a 20-mile drive. Lights up the dash and sounds a beep to inform the driver, while displaying a message on the dashboard screen. Again, this occurs every time the alarm activates. No dealership was able to get me in for an appointment when the issue first began. Took into the dealership today for diagnosis. The technician immediately knew the problem when I said the ABS light was blinking randomly and noted that he has seen this with all 2018 RAM 2500s. The first safety issue is regarding the loss of situational awareness while driving caused by distracting alarm systems. The second safety issue is that ABS WILL NOT work if the alarm is active, effectively setting up the driver to be placed into a dangerous situation during inclement weather conditions where ABS might mean life or death during a hard braking situation. The ABS system is only covered under a basic warranty with Dodge (3yr or 36K). The ABS system failed around 36K, but due to dealership waitlists, I was not able to be seen until 41K. The cost for total ABS HCU and control unit replacement is around $1500.

ABS hydraulic control unit failure causing ABS system to deactivate.

39,125 miles - 2018 RAM 2500 6.4L (purchased new in 2019), intermittent ABS / traction control light and alarm dinging! Dealership diagnosed it as the ABS / hydraulic control unit with code C0020-07. Many reports of this same issue can be found online from RAM owners having this exact issue, most are just out of the warranty. Low or backorder status of the replacement parts also suggests an issue. ABS function and cruise control are disabled when the error occurs and no way to know when or how long the issue and alarm dinging will last. This is a major safety problem that should be a recall.

ABS and Traction Control warning light keeps intermittently coming on and then a message saying that the Electric Brake system needs serviced. This has happened to my 2018 RAM at 17,000 miles. Dealer replaced ABS module under warranty and problem was solved. Now I am at 35,000 miles and the problem is back. Same exact issue. This needs to be a recall item ASAP and this seems to be a VERY common problem with these trucks. This could be very dangerous as these trucks are made for towing heavy loads and losing your anti-lock braking capabilities could be catastrophic to you or anyone else on the road.

The truck recently started displaying "Service Antilock Brake System" periodically on the information panel. Sometimes it comes on periodically while driving, sometimes only once, sometimes every minute or so and sometimes does not come on at all. We have not had this inspected but looking online appears to be a common problem in these trucks that should be considered a recall. Truck only has 50K miles when this started but this appears to start as soon as 3K miles on some other trucks. This should be a recall as the ABS system is a safety feature that should not be malfunctioning. A second issue that started shortly before this one is the steering wheel shakes when making turns and going over bumps. The truck was serviced for the drag link recall and this started shortly after that and is getting worse with time. Not sure if related to the ABS problem since they started pretty close together or if this is related to the 4WD as it shakes when turning similar to when the 4WD is selected but in this case it is not. This is also a safety issue as you could lose steering.

Vehicle has 21000 miles currently. Service ABS warning and anti skid disabled warning are intermittently flashing on cluster repeatedly. Brakes do appear to work but ABS is not I believe based on towing a heavy loaded trailer when coming to a quick stop in the rain on an irregular surface. Luckily the trailer has dual axle electric brakes and I was able to come to a stop safely. I have pulled the DTC code which is C002001 and states general electrical failure. Found reported Star case [XXX] in NHTSA website that was written in 2020. Have not been able to get into a dealer for service and they appear booked out to early to mid October. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Add me to the list of Ram owners with the "Service Electronic Braking System" and "Service Antilock Braking System" error codes, 2018 Ram has 30K miles, the dash lights up with these two errors then goes away, then comes back.

Service Electronic Braking system and Service ABS braking system messages with accompanying chimes occur every 2-3 seconds while driving. This turns off the traction control and abs as well as the speed control. Diagnosis reveals abs control module and hydraulic brake control unit needs to be replaced. Code c0020-01,Vehicle only has 22,000 miles. Parts are discontinued according to dealer site. I started getting a Service Electronic Braking System warning light and bell recently that is intermittent and seems to affect the braking system on the truck. The light will go off and then return, sometimes once and at other times frequently. I searched online for this issue and found this is common among the 2018 and later year RAM trucks. The dealers make repairs under the warranty or charge upwards of $1,000 to change components to clear the warning, sometimes resolving the issue and at other times the warning returns shortly after repairs were made. My truck has just over 22K miles and the warranty (36 months) lapsed in October 2021. I believe RAM has adequate historical information regarding this issue to recall these vehicles and replace the failing components impacting safe braking on these trucks. Some vehicles exhibited this warning with less than 10,000 miles on them. There is plenty of owners complaints available via internet sites, such as the RAM Forum, documenting this safety issue and the lack of support by Chrysler to resolve the problem. FCA RamCares was at no help at all, and kept referring to recall V06, which is the drag link welding of jam nuts, which is also a hack job of a recall.

ABS and Traction Control warning light keeps intermittently coming on and then a message saying that the Electric Brake system needs serviced. Assumedly if the ABS is not functioning correctly that could lead to a crash. After doing research and reading many forums I see this issue has been reported many times and there is a TSB listed for this. For a truck with on 33,000 miles on it I would not think a critical component like ABS should be failing.

Intermittent shutting down of ABS. Which as a truck designed to pull heavy loads, this is a serious safety concern. This is due to a faulty ABS module that has plagued a disproportionately large number of owners. The problem remains that Ram is not supplying the needed part to remedy the safety related problem.

The ABS system warning comes on when I hit a bump. The audible warning sounds as well. It happens multiple times during a trip, even a short trip. The cruise control is disabled when this as well. When this happens, the truck is harder to stop. It is a safety concern. There is a recall on 2019 trucks for the same issue. The 2018 trucks need this same recall.

The electronic brake light and ABS warning goes off intermittent and with hitting bumps. When this happens the cruise control shuts off. This leads me to believe that the antilock brakes and and will malfunction in a panic stop. This is a repeat issue, dealership has replaced the HCU and ABS modules twice within a three year window.

Ram 2500 truck "Service Antilock Braking System" and "Service Electronic Braking System" warning light and chime come on and off repeatedly. This problem has been diagnosed by RAM dealer as error code C0020-01 ABS Pump Motor Control General Electrical Failure. Solution per RAM is to replace ABS Hydraulic Control Unit, MOPAR part #68143491AA/AB; however the part is unavailable and on backorder with MOPAR's ETA of December, 2022. This problem started in June, 2022. I tow a 5th Wheel on long trips and this problem is a serious safety concern for my family & I. There are a multitude of complaints on various forums about this issue and the fact that the part is backordered for so long is an indication of a serious defect. When the warning light is on, the ABS system and traction control systems are disabled causing a major safety concern. I would like Dodge/RAM to replace the failed components and pay for installation and/or issue a National Safety Recall to remedy this defect.

The abs pump and module have failed on my vehicle leaving it without abs, skid control and traction control. This is a very common issue and known by the dealers and manufacturer. This has affected tens of thousands of Ram trucks anywhere from 1 year old to 4 years old. But is only covered under warranty 3 years or 36k miles. It is my opinion this is a safety concern and should be recalled by the manufacturer.

Vehicle antilock brake system and traction control system failed causing cruise control to disconnect at highway speed, attempt to stop the vehicle caused an out-of-control skid

ABS module and HPU failing. The ABS Module is losing communication with the HPU causing the ABS to turn off and on. The concern is if it turns of during an event where it is needed and increases the chance of losing control of the vehicle.

The electronic brake light and ABS warning goes off intermittent and with hitting bumps. When this happens the cruise control shuts off. This leads me to believe that the antilock brakes and and will malfunction in a panic stop. A brief review of google shows this to be a well known issue with multitudes of owner la having the issue. Parts on back order also an indicator of the frequency.

Service Anti-lock Brake System; and Service Electronic Brake System warning messages appear constantly on the dash.

The ABS on my vehicle malfunctioned and the warning lights appeared on about 8/1/2022. The mechanic pulled the error code C0020-01 ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. His research indicates the solution is to replace both the ABS Control Module and the ABS Hydraulic Control Unit at the same time. As replacing one without the other seems to lead to additional unnecessary and costly repairs to the same part. After contacting every Ram dealer in my area, there are no ABS Control Modules available anywhere. I then checked the internet and it appears that the ABS CM (part# 68347098AB) is not available anywhere with over 2500 on backorder at a single RAM dealership in Texas. It appears that there are many thousands of RAM owners with the same problem and the lack of a replacement part is troubling. The ABS system in vehicles is a BASIC safety feature and a malfuctioning ABS will undoubable lead to crashes and possibly deaths. As a owner of an affected vehicle, I request that you investigate this problem and force RAM to ensure that their vehicles are equipped with the basic safety features that are required by law.

Service Antilock Braking System and Service Electronic Brake System randomly turning on and off once vehicle is started. Sometimes they do not turn on at all. Randomly occurring. The Alerts were not there one day, and the next they were. No moisture, rain, or hard braking occurred to cause this. This is causing traction control and ABS to turn off which will be a major safety hazard once winter comes. This turns out to be a very common issue with these models.

The abs and traction control light is on and chimes non stop and my cruise control will not work when the abs and traction control is defective.It needs the abs pump replaced as do many of these trucks. The next issue is the computer sceen is delaminated and is wanting you to adjust the time and chimes non stop, so it will not allow you to turn on your defrosters so you can see the road. This truck is so unsafe it now just sits in my barn while I drive my 2005 ram with 210000 mile on it! The repair cost is around 5000,00 for a truck with 48,000 miles on it! All safty issues!

Keep getting service ABS system message. Doesnt matter weather conditions or road conditions, it is very random and becoming very frequent. Upon doing some research to figure out the issue, it has become apparent that this is a very common issue with Ram. The Hydraulic Control Unit needs to be replaced as stated by my mechanic that pulled the C0020-01 ABS Pump Control Motor General Electric Failure code. There are way to many websites and forums to list for reference but the issue can be found with a quick google search. Ram knows this is a problem and thats why they are limiting how many of these parts the dealer can get.

All started when the truck had 472 miles. ESC and service brake light came on. Was repaired on May 9, 2019. March 23, 20 back at dealer for ABS Light and ESC Lights on dash. Dealer replaced both the HCU Unit and ABS Module on truck. December 2, 2021 back at dealer again for the same HCU and ABS Light on dash again. Dealer replaced HCU unit but not ABS Module. August 2, 2022 HCU and ABS lights on again. Contacted dealer they said they would call back with service date but never got a call back. This is a very serious safety issue on these trucks. When the ABS and ESC Lights are on in the truck it disables the Antilock Break System along with traction control, brake controller and if you have 4wd it disables that also. I have had nothing but problems with this truck since it had 472 miles on it. Dodge/Ram refuses to address the problem correctly. They just put another part in knowing it will fail sooner or later and by that time your waranty is out and they want $1600 to repair something they know will break again. What will it take to have them correct this problem (someones life!) I will never but another Dodge product again. They refuse to find a fix for this problem.

ABS Module failed which makes the truck slide and lock up the brakes and makes cruise controll not work at all also turns off traction controll which can make the truck slide or skid in turns or on wet conditions.

I had to brake hard on the freeway to prevent being hit by an 18 wheeler that began to change lanes. Since that incident, every time I press the brake pedal more than 50%, the "Service Electronic Braking System" light flashes on the EVIC. I had the ABS pump replaced in July 2020 under warranty for the same issue, and was advised that it is a known issue, but there was not a recall that has been issued. I have not had any issues with the brake system since the repair until I actually needed it in this instance. This is a safety concern due to the fact that when this occurs, it disables the ABS system.

May 18 2020. 6,783 miles on truck ABS light and traction control light started flashing on and off. Drops out of cruise control. Then light stayed on all the time. Dealer replaced the complete brake system. Yesterday July 20 2022 same thing again at 39000 miles.ABS and traction control light on. Dealer said it's out of warranty. There are complaints of this issue all over the web and has been a issue for years. Why is this not a safety recall yet.

2018 Ram 2500 with 41,900 miles. ABS and Traction lights started coming on. Had to have the hydraulic control unit replaced. Seems like a known issue and very unsafe to lose abs or traction control. Ram should take notice.

The hydraulic control unit for the ABS brakes failed at only 17000 miles. This is a known safety issue with these trucks.

Service antilock brake system and service electronic brake system warnings come on

Brake system failed on 2018 Dodge Ram 2500 with 31,262 miles on it. Dealer stated electronic failures on ABS pump and hydraulic control unit.

2018 Ram 2500 4x4, 65400 miles, began having flashing and dinging from dash and warning lights for abs, traction control. Scan revealed code c0020-01, ABS control general electrical failure. It appears FCA is aware of this issue, but claims it not to be a recall issue, or covered under the power train warranty. I feel this is a safety issue, these systems help avoid crashes. This started as a simple quick light and went away, and at other times it goes off and on and dings, it’s distracting to who ever is driving these vehicles,

While driving my ABS system “ service ABS” and Service Electronic braking system “ light both flashed and my truck started to skip as it appears the abs system was trying to engage while i was driving, I immediately pulled over and turned off the truck. Now the lights won’t turn off. I was driving about 60 on paved roads. This appears to be a severe problem with the 2018 year model and if not taken care of I will bring legal action against Fiat Chrysler Ram and the NHTSA for ignoring these real issues that could potentially lead to a death

-Anti lock brake system control module and traction control system failure with 32000 miles on truck.- In reading online forums they have admitted to knowing these parts were bad. Not sure why this hasn’t been made a recall issue given it involves the braking systems on a huge portion of these trucks sold.- Dealership states both parts are bad but excluded from warranty and extended warranty.- warning lights come on at the same time it locks the brakes up until warning lights go out. -Well at 70 mph on the highway and it locked my brakes up. I was just lucky it didn’t cause a wreck or roll over accident which it very easily could have.

The EVIC display showed Service Antilock Braking System and alternated to Service Electronic Brake System. It would constantly ding and display the ABS light and the Traction Control light. It disengages the ABS and traction control system. Research has shown me this is a very common and known issue. It is dangerous and I am not comfortable driving my vehicle in the weather conditions I experience while towing heavy loads on a daily basis.

Electronic Brake System malfunction (ABS) warning message comes on intermittently with no rhyme or reason.

My 2018 RAM 2500 doesn't even have 23,000 mile on it, however went out of the 3/36000 in June of 2021. Currently I will be driving along and out of the blue the ABS/EBS "Service Breaking System" and traction control will light up and flash and ding. It will sometime go away quickly, however other times it keeps flashing the warning, and dinging upwards a minute. As seen on the site this is a very common issue with the 2018 RAM 2500, and it should be a Safety Concern and part of a National Recall. Many people use the 2500 to pull trailers and the like, and to loose any safety aspect relative braking is simply unacceptable and a dangerous situation for the owners and others on the roadways.

I started getting a Service Electronic Braking System warning light and bell recently that is intermittent and seems to affect the braking system on the truck. The light will go off and then return, sometimes once and at other times frequently. I searched online for this issue and found this is common among the 2018 and earlier year RAM trucks. The dealers make repairs under the warranty or charge upwards of $1,000 to change components to clear the warning, sometimes resolving the issue and at other times the warning returns shortly after repairs were made. My truck has just over 27K miles and the warranty (36 months) lapsed in February 2022. I believe RAM has adequate historical information regarding this issue to recall these vehicles and replace the failing components impacting safe braking on these trucks. Some vehicles exhibited this warning with less than 10,000 miles on them. There is plenty of owners complaints available via internet sites, such as the RAM Forum, documenting this safety issue and the lack of support by Chrysler to resolve the problem.

Service Electronic Braking system and Service ABS braking system messages with accompanying chimes occur every 2-3 seconds while driving. This turns off the traction control and abs as well as the speed control. Diagnosis reveals abs control module and hydraulic brake control unit needs to be replaced. Vehicle only has 60,000 miles. Parts are discontinued according to dealer site.

Mileage: 60,000

ABS and Stability light came on simultaneously several times. It seems there is a recall already for the 2019 Ram 2500 but not including the 2018 model. It seems my model could possibly have the same issue.

Abs control module. Service electric brakes soon. Traction control

ABS Electronic Brake System warning. "Service Antilock Brake System" warning as well as "Service ABS System" warning. Warnings are intermittent. It is available for inspection. Traction control light is on and braking seems difficult. I have not taken to a dealer because of prohibitive costs. This vehicle has not been inspected as it is a very common problem for this model truck. The problem has been intermittent for the past year or approximately 5000 miles driven (with only a total of 48,000 miles on the vehicle.

Intermittent alert on ABS and Traction Control warnings. These warnings are not consistent and come on/off. Researched and found numerous issues on this model vehicle for same issue related to ABS/Traction Control pump. Checked the speed sensors, all are working and reporting same speed. Dealer wants 2 days to trouble-shoot and there is no guarantee this will not return. I have owned other vehicles - GMC, Ford, Subaru, etc - none of them have failed on a critical item like ABS/Traction Control.

I have been having intermittent ABS/traction control lights flashing on my dash. When I hooked my truck up to my DTC code reader, it says I have a C0020-21 stored. ABS pump motorcontrol - general electrical failure. I have noticed thousands of complaints on various websites about the same issue. My truck only has 38,000 miles on it. This must be a defective part.....I called and asked my local dealership about this and they said its a very common issue. I believe it is a safety issue because it reduces the trucks ability to stop quickly, it may cause my truck to swerve in an emergency stop situation, and if this happens while the cruise control is on it turns the cruise control off unexpectedly. This happened to me in a bad rainstorm and caused my truck to swerve into the next lane over. I asked the dealer when they could get to repairing it and thy told me it would be months before they could repair it and it would cost approximately 1,800 dollars. They told me to just keep driving it with the error codes active. This is ridiculous. This part needs to be recalled because it affects thousands of vehicles and it is unsafe. My vehicle is available for inspection.

I was on vacation with my family and pulled over to the side of the road to get something from the back and the service abs electronic light came up. it was intermittently coming on and off. it really dampened our trip because i have been stranded with electrical issues in this truck before. my family was scared the brakes were going to fail and we reduced our trips into the mountain areas we had planned. being not fully trusting of this very expensive vehicle i thought would take me anywhere i need to go i tried to sell it back to the dealer, i signed all the sale paperwork feeling like today was the best deal and they wouldnt give me the same deal the next day. only to be told i needed to pick the truck back up because of the brake system hydraulic control and brake system module being not availiable. so long story short. they said i am stuck with this truck and this is not a recall issue. i cant find the parts, this is just out of warranty period, i do not feel safe driving this vehicle. i am actively searching and do see that probably thousands of owners have the same issues, hopefully i can get the updated part and resolve this issue.

The antilock brake system has failed and the ABS light is on. There is a C0020 Code stored with a description. ABS Pump Motor Control: General Electrical Failure. Mopar is unable to provide a repair part in a timely manor. According to MOPAR Dealer I need 2 parts with the following part numbers. 68347098AB Anti-Lock Brake System Module 68143491AA Anti-Lock Brake System Hydraulic Control Unit This seems to be a very common failure. My vehicle is just out of factory warranty at 41K miles. While I dont mind paying for the repair, the 68347098AB Anti-Lock Brake System Module is backordered with no ETA. Does not seem safe to continue to operate the vehicle without antilock brakes. Dealer has no ETA as to when this part will be available. I can't just park my truck for an extended period.

My issue seems to be a highly reported issue that the manufacture refuses to address. The ABS pump/control/module fails on this model Ram at an alarmingly high rate, causing loss of brakes, or locking up of brakes. I bought this truck just over 3 years ago and the first time it happened was about a year after I bought it with around 26,000 miles on the truck. I took it back to the dealer and they diagnosed it as a bad ABS control module/pump and replaced it under warranty. Since it was a safety issue the dealership even provided me with a free rental vehicle while the truck was being repaired. When the ABS pump/control module goes out the service Electronic brake system message comes up (see picture below) Fast forward about year and a half later and another 25k miles (the truck just hit 50k miles) and the same issue has happened again. The new ABS pump/control module has failed again with only 25k miles since the repair. And this time the truck is no longer in warranty so the dealership will expect me to foot the bill for something they know is a defective part from the factory. Here is the link to google search, if you read the complaints you will see there are thousands of people having the same issue. And many stories of accidents or near accidents because of the brakes failing. https://www.google.com/search?q=2018+ram+2500+abs+issues This is a serious safety issue that needs to be addressed immediately. If the factory part remains defective, then they need to develop a replacement part that won't FAIL every year or two. My truck just turned 4 years old and has 50k miles on it, which is right at the national average. The truck isn't over used or abused so there is no reason for the ABS to be failing not only on my truck but so many others. Please advise me of how we can remedy this asap. I'll include my contact info below. I can scan the papers from the first warranty repair for the ABS if needed.

SERVICE ELECTRONIC BRAKING CONTROL AND TRACTION CONTROL LIGHTS COME ON AND CHIMES. AFTER SEVERAL TRIPS TO THE DEALER AND MOST OF THE TIME THEY COULD'T DUPLICATE THE PROBLEM I FINALLY HAD THE LIGHTS TO COME ON AND WENT STRAIGHT TO THE DEALER WITHOUT SHUTTING DOWN THE TRUCK AFTER THE CHECKS THEY STATE ABS CONTROL MODULE AND HCU NEEDS REPLACED. PARTS ARE UNAVAILABLE FOR AT LEAST 6 MONTHS AND $1200 REPAIR COST. THE LIGHT COMES ON THEN THE CRUSE CONTROL STOPS WORKING AND THEN WHEN BRAKING HARD THE WHEELS LOCK UP AND CAUSES SKIDDING. TO ME THIS IS A SAFETY ISSUE THAT RAM NEEDS TO STEP UP AND REPAIR. ITS FEDERAL LAW THAT MANUFACTURES PUT ABS ON THE VEHICLES SO THEY SHOULD MAKE SURE THEY WORK CORRECTLY.

Every so often I am getting the “Service Electronic Brake System” and my ABS light and Traction Control Light come on. This has happened to quite a few Gen 4 and Gen 5 Ram’s. Everyone replaces the wheel speed sensors, wheel hubs and ABS sensors with no fix. Only thing after that is the Hydraulic Control Unit and ABS Control Module (which is on National back order until who knows when). The ABS system for some reason is not covered under the power train warranty, why I don’t know. It’s a serious issue that needs to be addressed.

Driving the ABS and Traction Control light comes on randomly, when on neither the ABS or Traction Control work when light is on. Cruise control is also not working when light comes on. Took Ram to dealer, they tested and stated a failure of ABS Module, took over a month to get in as they are in demand. Dealer stated this is a common issue and parts are backordered. ABS Module was replaced and system is still not working. This is a safety concern as no ABS and Traction control make the vehicle unsafe to operate. I do have the old ABS module on hand after dealer replaced old one. Dealer is trying their best, but always have one or two on lot with issue. Stopping and handling are hazardous when system goes out.

Was traveling westbound on highway when I got a chime and notification, "Service Antilock Brake System" and then another chime, "Service Electronic Braking System". The notification went away and both came on again. I was approaching a red light and when I applied brakes I had none. I swerved to the right and drove into a ditch. I was able to put it in 4 wheel drive and get out. While parked I started looking on YouTube and found a mechanic that advised pulling the 40 amp fuse to disable the ABS system. I did so and turned around and drove slowly home with brakes working but notification on. There were no I,juries or damage but had I hit the Fiat, with my truck, there would have been 4 dead. I notified Ram and asked why there is no recall as I looked it up and there are many incidence of this exact problem!

For at least 2 months I have been getting intermittent warning signals for abs automatic braking system and traction control which also causes you not too have cruise control. Without traction control wet pavement is dangerous. Vehicle just has around 20000 miles on odometer I am now out of warranty I took too get checked at Christian brothers automotive and they diagnosed a faulty abs module. The info I received from garage is that there was 1800 modules on back order so evidently ram has a big problem that they are failing too take care of. Repair would be $1300 if garage could ever get ahold of module and I ate cost of diagnostics. Please look into this problem and let me know. Thank you [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The ABS and Traction Light come on intermittently. We recently had snow fall and I had to stop quickly, the ABS worked as it should have until the light activated on the dash which disabled the ABS. Luckily I was able to control the vehicle when it started to slide into the on coming lane. It is definitely not safe. As I have seen in numerous complaints this is a well documented problem on the 2018 Ram 2500.

The ABS warning light intermittently comes on and turns off. After searching on-line, it seems that it is an ongoing problem with many others. I'm afraid it could cause a serious accident. I had the same problem about 10,000 miles ago and took it to Cape Coral Dodge to check it. They repaired it but here it has cropped up again. Every time the ABS Warning light goes off an alarm sounds and it drives you crazy. There really should be a recall on this to resolve the defect.

12,478 miles and abs & traction control warning lights on. Diagnostic code on C0020-01 ABS pump motor control - general electrical failure. Based on internet search this is a common problem. FCA Star Online Publication appears aware of issue. No ABS brakes is a safety issue.

I, along with hundreds (if not thousands) of other Ram 2500 and 3500 owners for years 2017 through 2018 have been having an issue with the ABS Module and Hydraulic Control Unit. Have contacted the dealership and it is a well known problem with the aforementioned parts, to the tune of a 3-6 month wait for the ABS Module. The module has a manufacturing defect that FCA/Ram will not admit to, and when in fault disables cruise control and causes ABS to malfunction, which could lead to locking up of tires in an emergency braking situation. This happens intermittently and sporadically for no apparent reason. I have video of the faults happening, but cannot upload the video due to it not being the proper format.

I have owned this vehicle from the beginning. The first thing that happened 4 wheel drive module went out causing my cruise and abs system go down took to the dealer found out the module went down they replace it under warranty. Then a couple months later the abs system went down again to it to the dealer they said the abs passenger side sensor went bad replaced it under warranty. Drove for about 6months lost abs again the same sensor went bad they replaced again under warranty. Then about 6 months the abs went down again that's when they said they hcu and abs went bad replaced it did fine. Then Dec 21 the abs started acting up took to O'Reilly here in town read the code this one came up c0020-01. Call the dealer gave the code to them they said abs most likely went out. Truck is out of warranty now by 5,000 miles. This had been an recurring problem that seems like no one wants to fix it, I haven't taken back to the dealer yet.

The ABS warning light would intermittently come on for any reason and then go off. Check some Dodge/Ram forums and noticed this occurring quite a bit

Service Anti-Lock brake system and Service Electronic brake system messages repeatedly display along with a distracting chime. Symbols for these illuminate and then go out. The dealer spent three and a half hours trying to determine the problem about a week and a half ago. They made an appointment to pick up the vehicle this morning to look at it again "after their electronics specialist gets back from vacation". No one picked it up and a call to the dealer revealed that they have no drivers available to come get it. The constant chiming of the warning is especially distracting when driving in traffic and the intermittent nature of the problem could actually cause an accident if it occurred while the systems were trying to control a skid.

Truck has intermittent abs/traction error on screen. It appears for a second or a minute. 40k on vehicle, dealer wants 1100 to fix… problem is parts are not available per dealer but Ram website shows in stock. When error codes appears, I loose cruise right away and deceleration plus I have no abs or traction control function. I tow a 7000lb in the winter. I feel that it makes the vehicle unsafe…

My 2018 Ram 2500 has over 45,000 miles on it and this is the second time that I have gotten the service antilock brake system and service electrical braking system warnings. The first time my truck was still under warranty and the dealer replaced the parts (I believe the ABS module and the hydraulic control unit) which seemed to remedy the issue until recently. Now here we are with the same issue coming up. Seems that the first time occurred when turning on a wet road and the second occurred while backing up in some mud at our camp. Seems like the culprit might be when one of the rear tires seems to slip/spin differently than the other. Considering this is my second issue with this and there seems to be more and more complaints online for the same exact thing, this might be a defect in the parts or some other underlying issue. I take really good care of my truck and don't abuse it and these parts should not fail this quickly.

The contact owns a 2018 Ram 2500. The contact stated while driving 60 MPH, the Service Electric Braking System and the ABS and Traction Control warning lights were illuminated. The contact took the vehicle to a local dealer, where it was diagnosed with needing the ABS pump to be replaced. The vehicle was not repaired but was pending repairs. The manufacturer had not been informed of the failure. The failure mileage was approximately 26,800.

Mileage: 26,800

The service anti-lock brake system light keep coming on and off on dash, sometimes every few minutes then it could be days before it happens again. Diagnostics code reader is listing C0020-01 - ABS Pump Motor Control General Electric Failure

While driving and sometimes sitting still, the Service Antilock Brake System warning will flash on and off rapidly. Then go off. When this happens cruse control stops working. Antilock brake functions no longer work. And traction control no longer works. I found this out while driving on snow and ice covered roads recently. I was stopping at an intersection, and the ABS system started to work then turned off and my tires locked up, causing me to slide into the intersection. Fortunately no one else was at the intersection. Online forums show a great number of low mileage Ram trucks like mine with this issue. Seems to be a failure of the motors on the hydraulic control unit.

My ABS system failed, taking out the cruise control also. I had to have my ABS module replaced under warranty by the dealer. The warning lamps were on and I was told this is ULTRA common on the 2018 ram 2500's, dealer wanted $1400 until they realized it was certified pre owned.

ABS system check light comes on. Dealer said the ABS Module has failed due to a "internal failure" meaning it is faulty (as per many others who have experienced this issue) and needs to be replaced along with the HCU and then the system needs to be flushed - all for $1400. The truck has 40,000 miles and is just out of warranty. If not fixed the breaks can fail and I would crash so they have said it HAS to be done to avoid injury. This module needs to be recalled and replaced.

ABS and ESC lights game on the dash. Diagnosed by the dealership as a hydraulic control unit replacement. Luckily I'm within the warranty still, but many others on the forums have reported the same issues and are just outside of warranty. Obviously, this should be part of a recall.

Vehicle antilock breaking system began cycling on and off during a stop. Service Antilock Break System warning began illuminating at about one second intervals.

Constant warning to service electronic braking system kicks out cruise control. According to ram this is a known problem with related module

The Service Electric Braking System and the Service Antilock Brake System warning lights come on with chime. I or other have not been put into risk of safety as of yet. No dealer will look at it right now. I have called 2 dealerships and they both told me that they have to many vehicles as of now to look at it. At what point is mine and others safety con into play? I need my truck for my business and can't afford to let it go for long.

ABOVE VEHICLE 2018 RAM 2500 HAS ISSUE WITH THE ABS SYSTEM AND OR ELECTRONIC BRAKING SYSTEM. ABS LIGHT BLINKS ALONG WITH TRACTION CONTROL BECAUSE OF A ISSUE WITH THE ABS MODULE AND OR ABS PUMP. THIS ISSUE IS WELL DOCUMENTED IN NUMEROUS RAM TRUCKS, NEW AND USED, OF A FAILING PART OR PARTS THAT CAUSES A SAFTEY CONCERN. WHEN THIS PART FAILS , YOU LOSE YOUR ANTI LOCK BRAKES AND IT ALSO PUTS YOUR VEHICLE WITH NO TRACTION CONTROL. THIS ISSUE NEEDS TO BE ADDRESSED AND A SAFTEY RECALL NEEDS TO BE ISSUED TO FIX THIS PROBLEM BEFORE SOMEONE GETS HURT OR KILLED DUE TO THEIR VEHICLE LOSING CONTROL DURING BRAKING OR DURING ACCELERATION.

While driving my 2018 Ram 2500, the Service Electrical Breaking System and Service Anti-locking Break System flashes on and off. It usually does this while traveling on a bumpy road or driving over railroad tracks. Sometimes it will go days without coming on and some days while driving it constantly beeps and flashes the entire time while driving and it really distracts me from driving. When I called my local Ram dealership Lander's Dodge Bossier City, to make an appointment, they knew that it was a 2018 Ram 2500 before I told them. The first available appointment isn't until 22 November 21.

The "Service ABS" light started intermittently going on and off on our 2018 truck. The truck has only 8,400 miles on odometer, and the issue started just three months after the bumper to bumper warranty expired. Taken to the RAM dealership and to an independent shop we were told that C0020 ABS pump motor failed and ABS pump and module must be replaced and reprogrammed. After doing some research on the web, we read of several cases identical to ours,. Still the dealerships did not offer any assistance and we are waiting to hear back from FCA/RAM. Since the issue is well known and common to a large number of vehicles (just google the error code) we wonder why this is not part of a recall. Braking systems are an integral safety part of the vehicles and the fact that the manufacturer is not acting on this issue despite being well aware of it being a common problem on their trucks is just irresponsible.

The abs light and traction control light came on with chiming going off. The lights would go on and off at random. Didn't start till I washed my truck. Took to dealer they said the ABS module bad and ordered it. They say warranty will cover it. They shut the light off and reset the system. Stayed off till I washed the truck again. The part is in just need to have taken to shop to put on. This should be a RECALL for as many of these trucks that this has happened too. The cruise control, won't work and how do you now that the brakes will stop the truck if someone pulls out and you hit the brakes hard if the ABS system isn't working right. They inspect the truck and see that the ABS system was not working who is liable in a law suite. Chrysler won't say that it is a problem. Something needs to be done about Chrysler (or any manufacture) responsible for the safety of the consumer buy there product. The truck only has 21,536 miles on it now. If it wasn't under warranty it wouldn't be fixed. It had 20,659 miles when went in to dealer. it had 20,583 miles when the light first came on.

2018 Ram 2500, 45637 miles. Service Electronic Braking System and ABS/TRACTION CONTROL lights illuminated. Code present. C0020-1 = ABS PUMP MOTOR CONTROL. ELECTRICAL FAILURE. This is a known issue and a technical bulletin and star report has been produced. Chrysler needs this as a recall as these are all low mile vehicles and the end user had no input on the component failure. ABS problems are a safety issue and required to work properly according to the law.

The display on the instrument panel said service anti lock brake system and service electronic braking system. Also a warning chime sounded and warning indicator lights for the anti lock brake and traction control malfunctions came on.

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. I called the dealership and was told by service advisor at Maik Haik Dodge in Temple, Texas this is a common issues and Ram knows about it. It is effecting Ram trucks from 2014 to 2018 models 1500 to 3500. This issue turns off all ABS, Traction Control and Disables cruise control. The Abs and traction control light goes off and on constantly. message on the dash is service ABS system and service electric brake system.

ABS light came on. Dealership said that ABS Control Valve is defective. Could lead to safety issue. Have read on several forums that this is a reoccurring problem with this vehicle. My vehicle has only 30,000 miles. Have only owned it for three years. Should this be listed as a recall item? Warranty declines to cover.

The anti lock brake and electronic braking system are throwing alerts on dashboard. It cuts off cruise control as well. This is a safety concern for us and other vehicles. On all ram forums there are complaints wanting to start a class action. This is a very common problem with the ram trucks. It costs $800-$1000 out of pocket. These sensors are a safety feature that one would expect to be able to depend on. The negligence of these safety features need to be addressed.

Abs and tc lights come on and ding randomly, freedom service told me it’s a hydraulic pump and causes a safety issue it also knocks cruise control off when it happens. The dealership said they have changed many so I am sure ram is aware of this issue.

Intermittent dash notification to Service Electronic Braking System It is the braking system and there is noted thousands of these failed systems at very low vehicle mileage I have not had it in the shop, it just started yesterday but during my investigation of possible solutions I found thousands of the same problem going back years, Ram is well aware yes, the dash board lights and dings as well as a written dash warning. I also got the info on my cell phone

ABS module, HCU module Currently available to be inspected if dealer won’t fix. Potential loss of brakes. Dealer confirmed I had codes relating to a known problem with both abs and hcu modules. Dealership ran diagnostics. Service braking system warning lamp appeared on dash. Codes C0020 and U0147. FCA star letter case #: S2005000004 Letter relates to codes stating general electrical failure. Dealership wants to charge me $785.21 to fix. They started by saying the cost would be close to $2800, when I asked why so much, they said I need several other repairs but couldn’t provide a break down. I brought my vehicle in with the letter about the faulty equipment and the codes and was told it would get taken care of.

the service abs and service traction control come on if i hit any bump on the road, seems to be a common problem with this vehicle model.

Traveling West on I10 Mobile, AL it was raining and the ABS and TCS system lights started flashing along with a waring bell. this was repeating about once every 10-15 seconds. The road was in the process of being resurfaced and was rough. Return home to make an appointment with the dealer and was told five days was first available. Used a bi-directional scan tool to verify the fault as a ABS motor connection fault. Purchased the OEM hydraulic control unit installed and corrected the problem. After replacement the bad unit dc motor was found to be open no electrical connection. I have also performed a simple failure analysis. I found that one of the two DC motor brushes to be stuck in the brush holder. this appears to be causing intermittent connection faults on the rough road and total failure in the near future. I have found that the other brush that was making contact with the motor armature could be pushed into the brush holder and would also stick for a short time. This looks to be a design and or tolerance issue. I cut the outer motor housing with a small metal cutting wheel, while removing the armature probably pushed the bad brush into it's deeper position with no contact. I have all the parts if the NHTSA would like to inspect the motor.

I HAVE A 2018 RAM 2500 WITH 24320 MILES ON IT. THE TRACTION CONTROL LIGHT/ ABS/EBS SERVICE LIGHTS COME ON WHEN DRIVING. THE SPEED CONTROL GOES OFF. I HAVE SEEN ON THE RAM FORUM THAT THIS IS COMMON ON THIS AND THE 2017 YEARS TOO. MY QUESTION IS IF THERE ARE SEVERAL 100 PEOPLE WITH THE SAME PROBLEM. WHY HAVE YOU NOT ISSUED A RECALL. THIS WILL GET SOMEON KILLED IF THEY ARE NOT CAREFUL.
