2018 RAM 3500 Vehicle Speed Control Problems

There is an open recall (C4B) for my Ram truck. The ABS light and "Service Brake System" light and message are currently displayed on the truck's dash. I contacted FCA about a year ago and told them I have an active issue. They said they placed me on a priority wait list but the remedy is not available yet. It is unacceptable for them to not have a remedy ready for an 8 year old truck when the issue was known about some time ago. I would appreciate if NHTSA or other government agencies would put pressure on FCA to repair this issue as owner's and other motorists lives are on the line if faulty equipment is forced to drive on public roadways. Thank you

Since January 2023, my truck stability control system has been disabled related to CB4 NHTSA 24V-896 recall. TWO years! I can't sell the truck like this & I have no idea when it will result in an accident. Stellantis needs to be held accountable. Every contact with them results in a response of waiting for parts. I've had no choice but to drive another 18000 dangrous miles with this vehicle. This is unacceptable.

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the brake, cruise control, and ABS warning lights illuminated. The contact stated that the cruise control and ABS failed to function as intended. The contact stated that when the brake pedal was depressed, the vehicle failed to stop as intended. In addition, the contact stated that a beeping sound was persistent. The contact was annoyed by the persistent beeping while driving. The vehicle was taken to the dealer several times; however, the cause of the failure was not determined. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. In addition, the contact was informed that parts were not available to repair the vehicle. The contact received notification of NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part for the recall repair was not available. The contact stated that the vehicle could not be traded because of the unrepaired recall. In addition, the contact stated that the failure started two years ago, and the recall was initiated a year later. The manufacturer was made aware of the failure but provided no assistance. In addition, the contact stated that the manufacturer was contacted several times and informed the contact that the parts were not yet available. The failure mileage was approximately 40,000.

Mileage: 40,000

Almost got into a wreck because my ABS failed. I was going down the interstate with my cruise control on and my abs and traction light came on. My cruise control.immediately stopped working and I was almost rear ended. I called the Ram dealership and they said they have no time frame of when they will have parts in to fix it under the recall. Does someone have to die before Ram will start fixing these abs units. The recall has been out since Nov 2024. They need to be held accountable or buy back all 2017 and 2018 rams affected by this.

No solution for the antilock breaking system,causing drivability issues and loss of traction control,abs and control on numerous occasions.

Traction control and ABS work intermittently. Ram sent out this notification for recall concerning stated problems but state there is no fix at this time. They continue to state there is no fix. This is a safety issue and you are not forcing them to repair. They are dragging their feet hoping it goes away. DO SOMETHING!!!!

The Hydraulic brake control has been a recall with no replacement part available for over 2 years and this causes many safety functions to not work properly including trailer braking. They have made parts for a 2500 model but neglected to fix the 3500, 4500 and 5500 models. They will fix it with another faulty sensor and still expect owner to pay a 1700 repair bill even though it’s a recall. It’s ridiculous on the time this is taking.

24V-896. This recall is a safety issue known for years. There is still no action from the manufacturer! I was extremely lucky to avoid a serious collision. The only solution the manufacturer offers is to authorize a dealer to replace the parts with another secondary market provider part, but they won’t cover the cost or warrant the replacement. How many YEARS do I have to drive an unsafe vehicle?!!!

Audible alarm, warning lights on dash. Come on and off. No cruise control available.

Continually gets abs stability error. Unit has been replaced once less than year ago. Comes on if vehicle sits or hits a bump. Lose of abs cruise and continual dinging.

The service electronic braking system and service abs system continues to ding and pop up on screen. Cruise control will not work either.

ABS-Hydraulic Control Unit failure, pump motor control electrical failure. Confirmed/ Diagnosed by dealer. Messages on dash info screen: "service electronic braking system", "ABS failure", warning lights : Traction Control and ABS failure. Safety risk when warning message appears: ABS, Traction Control and Cruise Control are non- functional.

my traction control, cruise control unavailable, and warning light to service abs electrical system. Dealership said the hydraulic control unit has to be replaced.

My 2018 Ram 3500 DRW truck for no reason started throwing dash warning lights intermittently after 60,000 miles. The warning lights activated on the dash were for ABS and Traction Control, with an annoying ding when they appeared. The center dash light stated "Service Antilock Braking System. Additionally, when this occurred the cruise control did not work. The warning lights were intermittent and just occurred at any time and disappeared as quickly as they showed up. This would happen for miles and for no apparent reason just stopped for a period of time. I took the truck to the dealer who informed me that its a known issue with the ABS HCU and the truck would be safe to drive but I would not have ABS and cruise control would not work. They also said parts were not available and could be a six month wait. They also told me that there were no recalls on the problem. I received a quote for repair which was in excess of $1,500.

Service Electronic Braking Service and Service ABS/TRACTION CONTROL. This is intermittent. When it happens Cruise control, 4 wheel drive and abs doesn't work. Happens when I'm towing my camper or not. Trailer brakes won't work when this happens. Hundreds, maybe thousands of complaints about this on Ram forums. This problem occurs no matter what the speed is. It even happens while sitting still.

Hello, I have an issue with the ABS Braking system on my 2018 RAM 3500 with only 50K miles on it. The lights are constantly coming on and off telling me that my ABS system needs servicing. this has been going on for two weeks. I was able to troubleshoot the problem and it says that my ABS pump and Module needs replacing. I was going to replace myself and when I ordered the parts from MOPAR they told me it was a 2 month lead time which I thought was unacceptable being such critical components to a vehicle. This week I almost rear ended another vehicle because the brakes failed. I have been online reading about the stories of these same complaints from many RAM & JEEP owners. How this company is getting away with safety issue is beyond me as this is going back to 2023, how are there no safety recalls on this not issued yet and customers not being reimbursed for the repairs. The issue was diagnosed by my independent mechanic using his scanner. If you require further info on this please feel free to reach out to me.

1. The specified vehicle has intermittent ABS/ Brake Hydraulic Control module error. The vehicle is available for inspection upon request. 2. Error causes ABS and Cruise Control to be disabled while in motion as per warning messages displayed on instrument cluser and audio annunciation. 3. Driver and passenger were endangered due to ABS malfunctioning intermittently **while in motion**. I have reproduced the problem by causing a wheel slippage on wet pavement. This will cause the otherwise intermittent problem to be asserted with corresponding error messages/notifications to be displayed on instrument cluster. 4. The specified vehicle has NOT been inspected at a Ram dealer; however, the problem seems to be well-known on 2017-18 Ram 2500's and 3500's given the amount of Youtube videos on the topic as well as the amount of discussion on online forums such as [XXX] . 5. This 2018 vehicle has approx 43000 miles on it. The described problem was not detected until about 3 months ago (approx 8/2024).

THE ABS BRAKES YES IT IS AVAILABLE FOR INSPECTION BY NOT HAVING ABS BRAKEING WHEELS HAVE LOCKED UP HAVE NOT HAD DEALER CHECKIT HAD A MECHANIC PUT ON COMPUTER FOR CODES NO TRUCK HASN'T BEEN INSPECTED BY ANYONE ELSE BUT THE MECHANIC WARNING LIGHTS HAVE COME ON AND OFF A NUMBER OF TIME AND LATELY MORE OFTEN IT STARED ABOUT A YEAR AGO TOOK IT TO DEALER THEN BUT WASN'T REPAIRED PROPERTY

Intermittent loss of anti-lock braking system and cruise control. code C0020-01 ABS pump failure. First occurred at approx. 47,900 miles.

I started getting an intermittent error code on my truck with only 36k miles on it. the traction control, abs and cruise control wont work when the service electronic braking system code is present. I have done a lot of reading and this seems to be a very common issue with the 2017 and 2018 ram trucks. It is so common that I called my local dealer and the part is on back order for months. I am getting very close to taking a long road trip with a 20ft trailer, which is the reason I purchased this truck. Now I cant even get a replacement part, that is a known issue and I was quoted $1100 for it. Braking system seems to be a safety issue, why isn't ram doing something about this issue!

On September 8, 2024, I started getting intermittent ABS and Traction Control light with “Service Electronic Braking System”. Code C0020. When the light is on I lose cruise control. There is no specific condition that will cause the light to come on; i.e. bumps in the road, a certain speed, or setting at idle. The first instance of the light coming on, I was turning around in a parking lot, less than 5 mph. This cannot be associated to normal wear and tear. THIS IS A SAFETY ISSUE AND MUST BE A RECALL!!!

Intermittent chime and warning that anti lock brake needs servicing. Cruise control does not work when notice is displayed and chiming. warning comes and goes randomly After researching this problem it appears that this is a regular problem on this year ram truck I will report and take to the dealer if problem remains.

We bought this truck from a dealer in March of 2023. We were never informed by the dealer that the truck had this issue. ABS light and traction control lights come on & stay on for periods of time. Sometimes lights come on & off repeatedly while driving along with chime on & off. When lights come on, there is no cruise control available to use. I took it to the dealer we purchased from over a year ago and was told there was no solution for the problem. They said it was under an engineering review. No parts were available for a fix. I have documentation from the previous owner that this was occurring when he owned it in April of 2022. Since we pull trailers with equipment and also a large fifth wheel camper, we feel very unsafe when the ABS braking system and the traction control goes out while driving this vehicle. It is available for inspection upon request. When will there be a repair for this?

A diagnostic code has been displayed for the Anti-Lock Brake System - C0020-01 —> ABS Pump Motor Control - General Electrical Failure. Going over a bump in the road will cause the ABS system to deactivate the cruise control. The diagnostic code can be cleared and the cruise control will resume. Reading on RAM / Cummins online sites, many say that either the HCU and / or ABS Module needed to be replaced and many submitted reports to the NHTSA to start an investigation. No damage has been evidenced at any of the wheel sensors. With the ABS illuminated, it appears that the unit wouldn’t function if needed. The clearing of codes has been done numerous times. First noticed in about January 2024.

The ABS system failure and traction control lights came on and have been coming on intermittently. This failure has caused the vehicle not to retain cruise control and brake and stability control being reduced or potentially off could result in an accident. Upon research, this is a very common and costly issue not covered by warranty work, this seems to be something Ram should fix as it is a safety issue.

The contact owns a 2018 Ram 3500. The contact stated while driving at an undisclosed speed, the ABS warning light illuminated, and the cruise control failed to activate. The dealer was contacted and stated that the failure was a known issue. The dealer stated that the ABS Control Module needed to be replaced. The vehicle was not repaired because the part was not available. The contact was placed on a waiting list. The manufacturer was not made aware of the failure. The failure mileage was 67,500.

Mileage: 67,500

We receive a ABS/ECS, electronic brake control warning intermittently. This also makes the cruise control shutoff. We had the ABS control module replaced once at roughly 12000 miles under warranty but it now is giving the same warnings and the truck currently has 22000 miles on it. My dealer stated this was a known issue and stated it’s fairly common on my model truck

I have a 2018 RAM 3500 with ONLY 20,000 miles on it. ABS and HUC critical parts are faulty, and I have no way to even purchase one until a recal is issued. Class Action Says 2017-2018 Ram 2500, 3500 Equipped with Defective Anti-Lock Braking Systems. No current part that resolves this issue. Ram 2500 and 3500 pickups are unsafe because they’re equipped with defective hydraulic control units (HCUs) and anti-lock braking systems (ABS). RAM knows about it and has ALL the modules on engineering hold. These parts have not been available for almost a year. No antilock brakes. No traction control. No cruise control. 4X4 four wheel drive system is locked out and cant be engaged after this warning occurs. Here's what they are telling customers who have filed with them about this. Good Morning Mr xxxx, As of 06/26, No new update Part: 68228991AD Module Order: xxxx Per CLIMS: Part STOCK is under QUARANTINE pending quality / engineering review and inspection.

Pending response from SPLR / PKG Working to improve xxxxx Case Management 844-378-0575 Ext:4063199 My dealer said, be lucky if they ever have parts for a permanent fix. I can’t haul anything or use cruse control. Error lights keep popping up sporadically with dinging sounds, driving me crazy. It is "Service Electronic Brake System" with continuous ABS and STC fault warnings. This truck is dangerous to drive, a recall is a NO BRAINER!!!! I am writing for three reasons. 1. You need to get our dealer the parts now so we may have a safe vehicle, or 2. replace this truck with a new one if you cant repair ours ASAP, and 3. To make sure I have this all documented in case of any serious accident where you will have to assume all liability and responsibility if this occurs due to your lack of ability to repair this safety system.

The contact owns a 2018 Ram 3500. The contact stated that while operating the vehicle, the ABS and traction control warning messages were displayed, and the cruise control feature became inoperable. The cause of the failure was not yet determined. The manufacturer and local dealer were not yet notified of the failure. The failure mileage was 6,000.

Mileage: 6,000

Vehicle produces code C0020-1 ABS pump motor control failure, vehicle disengaged cruise control unexpectedly causing rapid deceleration. Dealer states ongoing problem with 2018 Ram 3500 HD trucks

ABS system - flashes on and off dash, ABS has been inspected by dealership. Dealership said, could replace ABS but it could very likely have the same issue due to part malfunction. This malfunction causes- no cruise control, no traction control, sounding and lighting up on dash constantly.

ABS/Service Electronic Brake Control and Cruise Control lights constantly flash and chime while driving. Have been told that replacements parts have been on back order for over a year now. Any help will be appreciated.

Antilock brake warning light that says service antilock brake system comes on often if you hit any bump or rough spot. It continually dings and then the cruise won’t work. We have been told the part to fix it is unavailable. It is a horrible thing that cannot be repaired.

At 9,040 miles, display reads “Service Antilock Brake System” along with warning lights for abs and traction control and a loud dinging. It goes off, then back on multiple times until serviced when the dealership replaced the faulty HCU Sept. 2020 under warranty. Diagnostic code C0020-01 ABS pump motor general electrical failure 2023 the problem comes back but nothing done. 2024 after much research, found the newer replacement HCU had just been revised in April with a new part number. At 25,837 miles back to the dealership for another replacement, this time paying out of pocket, over $300 for part and over $600 for labor. It’s only been a short time but so far, no warning about a faulty abs. I do have the old part if inspection is necessary. There is an FCA service bulletin out #S2005000004; NHTSA #10181550 It says if the HCU doesn’t fix the problem, replace the ECU, but that is not available and no ETA. Lucky to get the HCU because that is a very limited part. This is a safety issue because not only does the ABS and traction control go out but you also lose cruise control and 4wd while driving. There should be a recall with all the complaints. Not sure what good a recall would do if parts aren’t available anyway. Telling someone who just spent a fortune on buying this truck not to drive it because of this, is not an option.

Electronic Braking System failure. ABS lights come on the dash, chimes constantly and disengages the cruise control. The vehicle looses ability to use ABS. Ability to control vehicle safely when ABS disengages is a critical failure. I'm told by the dealer that NO parts available from the manufacture to cure this issue. This is an unacceptable answer to a known issue for years. Many RAM owners have complained about this on RAM related forums and on YouTube. I am adding my vehicle to list of vehicles impacted by this catastrophic failure to create a safe vehicle to drive. Why has the NHTSA not fined RAM and forced a recall? How many people have to die from ABS braking failure to qualify for a recall? I don't want to be the last death before something is done to make my truck safe to drive.

While driving, the "service electronic brakes " and traction control light will come on periodically, then go away. The issue is random and not consistent or easy to predict. If the cruise control is active, the cruise control will disengage and the truck will start to slow down. The brakes seem to work the same even if the light is on or off.

The known issue that Ram refuses to is plaguing my truck. ABS and Traction Control lights come on. This shuts off the cruise control as well as makes braking difficult. It is very dangerous. This is a ticking time bomb. Vehicle has under 50k miles on it. 2017 and 2018 have been known to have faulty ECU Module and HCU. Loss of brakes momentarily occurred on [XXX]. I am having the issues under investigation.

For over 3 months the ABS Brake warning, the anti skid control and the cruise has not worked in my truck. I have had it to two different dealers, and opened a case with Ram. Case#89336043. They told me part is not available and has not been for the past year. Just drive my truck like it is??? I dont really know what options i have at this point. Please help!

The warning light comes on and then the traction control goes off and the cruise control will disengage all at once. There is also no trailer brake assist. This has been verified by a dealer in Columbus, GA. It is constantly going off and on. The warning light and the warning bell are a constant distraction to the driver. The truck was bought and within 50K miles it started. No warning.

ABS module problems. Flashes to check service ABS and traction control. Then goes away and comes back. Been having issue for over a year with no results in fixing

VEHICLE: 2018 RAM 3500 Dually ISSUE: ABS Module failure RESULTS: Loss of traction control, cruise control, and brakes locking up while pulling heavy loads. A constant chiming from check engine light. INSPECTED: By several independent garages can not find replacement module. Willing to let be inspected if need be. CONCERNS: Brakes lock up and loose control,Cause a accident by rear-ending someone, can't use all the functionality of the truck such as cruise control. Iritating chiming sound make long trips unbearable.

In May of 2023 while towing my boat I got warning bells and flashing lights, alerting me of the failure of the ABS brake system. In a few miles the warning went away. Then came back on, about 12 times in 20 miles. I also lost my cruise control and traction control. I took to the dealer, about 10 times before they were able to have the episode happen. It was intermittent at first but VERY annoying and Unsafe. The ABS system is almost always in failure mode and has been since about August. They order the parts in June, I'm still waiting. I use the truck to tow a car , a 34 foot 5th wheel and numerous other heavy loads. ABS is very important as is the cruise on my long trips. I'm still waiting, no help at all from Chrysler corporation!! Almost everyone I've talked to with a 3500 and larger truck, has had it fail. I'm tired of paying for a vehicle that is unsafe to drive. I want Chrysler to offer to buy it back, offer a good trade or repair. Please make them fix what they sell!!

In 2020 my abs traction control warning light came on took truck to dealership. They replaced ABS motor. 1 1/2 year later the warning lights started to flash on which progressed into always on by April 2023. I had the truck at dealership for another recall and they tested and system. Dealership stated they would repair under warranty. I have been waiting 10 months for repair and they state they cannot order the part yet 3/2/2024 since they can only order so many per month and there is a long list in front of me. I have noticed a loss of braking power. And I am not able to use cruise control either

My ABS and Traction control lights will come on and off, making my cruise control stop working without warning. sometimes it stays on and sometimes it goes off. it is completely random. I'm seeing lots of reviews saying this is happening to others and its the HCU module and the abs control. please help get this fixed

ABS and traction control lights intermittent flashing. Service ABS warning flashes and chiming occur. Very distracting and makes me unsure of failure of system .Codes and stored messages clear and repeat. Cannot go to dealer every day to have codes read that don’t exist. Parts not available at dealer. How is this fixed?

ABS mogel is defective and needs to be replaced. ABS light and chimes come on constantly. Affecting braking and lose of cruise control ability. This is a know fact that it is a defective part on ram trucks.

The contact owns a 2018 Ram 3500. The contact stated that the ABS hydraulic control unit was making an abnormal beeping noise. While driving at various speeds with the cruise control engaged, the system disengaged without warning. The vehicle was taken to the local dealer, and the contact was informed that the ABS system needed to be replaced. The vehicle was repaired, but the failure recurred. The contact called the local dealer and was informed that parts were on backorder. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 78,000.

Mileage: 78,000

The ABS light and Traction control light keeps coming on and off very frequently. I am being told it is the Hydraulic control unit, as well as the abs module. This seems to be a huge safety issue that many people are running into.

Vehicle began flashing abs light and traction control light. Took vehicle in for repair. Was told this is a known issue and they are unable to aquire parts until june 2024 currently January 2024. Drove on 1-25-24 light was off used the breaks and abs light came on and breaks locked up and continued to skid on the ice almost causing me to go threw a stop sign into a ditch.

The antilock brake system warning light because it's faulty The brake system affects the speed control And they don't have reliable parts to repair

In September 2023 I started getting a warning to service the ABS system. The warning and associated annoying tone would appear and than disappear at different times. I spoke with the service manager from Lithia Dodge where I purchased the truck. He told me that he was unable to service my truck because the ABS parts are not available. I was told that like a great number of Ram truck owners, I had to "hurry up and wait for a solution." This is unacceptable. To make matters worse, I am moving out of the country in February. I had a buyer for my truck and now it is un-sellable due to this ABS issue. I hope that a re-call will be issued soon so those of us with this common issue can get some relief. Thank you

Dealing with intermittent service brake system messages for over a year now. Light is constant now which means my ABS / anti skid/ and cruise control no longer function. Believe this is the ongoing HCU / ABS module known issue. Frustrating going into the winter months with such a heavy vehicle and loss of safety feature with no fix from Ram.

Traction control and abs lights have been coming on randomly while driving over the past several years. Seems worse and more frequent in cold temperatures. Scanner reads code C0020. Cruise control suddenly shuts off when this happens causing a safety hazard especially to those traveling behind. Dash lights and constant chimes are very distracting while driving. No abs makes winter driving more dangerous as well. Seems to be a common problem with this vehicle. There should be a recall issued to fix this.

The Hydraulic Control Unit Chrysler part number 68143491AA failed and was replaced on my vehicle. I had the vehicle back to the dealer numerous times before they replaced this item. 14000 miles later the same problems are happening again. 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. The warning lamps and messages will flicker on and off repeatedly and randomly while driving.

ABS and traction control warning lights intermittently come on. Has been repaired twice by local dealership by replacing the two computer modules/pumps responsible for ABS system. Cruise control disengages when this happens. When this happens at highway speeds while pulling a heavy trailer in traffic it's a very dangerous situation and needs to be corrected by manufacturer.

I purchased my Ram 3500 new, in 2018, at Nucar auto dealership in Tilton, New Hampshire. When I reached approximately 24,000 miles, my "Check ABS" and "Check Traction Control" lights activated on my dashboard and the message console. I was using cruise control at the time, which immediately deactivated. This could have caused an accident if I had been slower to react. The warning/failure was intermittent at first, but over the next few days became almost constant. The lights/warning would flash, the warning bell would ring, and then shut off for a minute. Over, and over, and over. I brought the truck to the dealer and they ran a diagnostic. They diagnosed the following: C0020-01 - ABS Pump Motor Control-General Electrical failure INTERNAL HCU OR ABS MODULE FAULT. WILL NEED TO REPLACE HCU AND RETEST The truck only had 24k miles on it, but since it was past the 3-year warranty period, they quoted a cost of almost $1,000 to do the repair, not counting the $155 they charged to run the diag. They also stated that the parts were on backorder, and wouldn't be available for some time. Since then, I have driven the truck as little as possible since it is a safety issue. Based on information in online forums, I know that this is a problem in thousands of 2017-2018 Ram 2500&3500 trucks. My next step is to join one of the several existing class-action lawsuits, create a new class-action suit for New Hampshire, or file an individual suit. Will Ram issue a recall for this?

My 2018 Dodge Ram with 7175 miles on it has a continuous service anti lock brake and service electric brake light go on and off.Cruise control inoperable as it shuts off when the warning lights go on and off.Dealer did a $160.00 diagnostic on the system that I had to pay for only to tell me the hydraulic control unit needs to be replaced at a total cost of $825.00 that I am responsible for.Additionally,the part is “controlled” by the manufacturer and they are allotted one unit per week.No time frame when the vehicle will be repaired.This is a safety issue especially when the constant “chime “ goes off which is very distracting.I haul a camping trailer with this Ram 3500 duelly four door diesel four wheel drive and the braking is questionable.

The Hydraulic control unit has failed. It has been taken to a mechanic and diagnosed. The electronic part has been replaced per my warranty info and mechanic recommendation and it is still failed, meaning the main HCU is the issue. The cruise control will shut off automatically and the ABS and traction control do not work while in fault. While towing a trailer up an on ramp, the HCU went into fault causing the traction control to fail and the pick up lost traction and started sliding sideways...Luckily I was able to get it under control without crashing. This was all due to the HCU intermittent failure, causing the traction control to stop working. While this is faulted, the ABS also does not work.

My ABS and Traction Control components in my 2018 1-ton Ram are intermittently setting codes with the ECU, leading to loss of ABS, Traction Control, and inability to use my cruise control. I am concerned that I have a loss in braking performance without those components operating as designed. I have brought my truck to the local Ram dealer only to be told that the module will not be available for install until Feb of 2024 after an upgraded unit is made available to the dealers. I feel that this should be a recall, as a quick internet search shows multiple owners of the same vehicle are also affected.

Anti-Lock Braking system and Electronic Braking system, service system warning come on and off randomly all the time. Seems to happen when bumpy roads are encountered.

ABS and Electric Brake System warning lights are on and off intermittently. These symptoms have been reported by many other owners due to defected part installation from the manufactor based on my internet research.

My ABS light and Vehicle Stability Assist/Traction Control light came on. I now do not have the ability to use my cruise control. I believe the vehicle is unsafe.

UNKNOWN. abs pump problem

At around 50,000 miles my truck began to turn off cruise control while driving, ding, and the ABS ,as well as, the traction control light came on. It goes on and off repeatedly while driving. This is incredibly distracting and quite possibly dangerous for braking and handling. The local dealership is aware and have stated that even though it is still under warranty, there is no available part to fix it.

The ABS/ Traction control is intermittently failing. It is aviliable for inspection. When the light comes on I have no ABS or Traction control which may cause me to lose control under certain circumstances. The dealer has and the manufacturer has confirmed the problem. The dealership was able to reproduce the issue. The component was inspected by the dealership. There are the ABS/ Traction control light that comes on the dash sometimes. I have been told that the part that needs to be replace is backordered indefinitely and the manufacturer has no idea when they will get any new ones. From what reasearch I have done it looks like they need to reengineer the parts to make them work right. Also told that this is not covered by any recalls which I think is wrong as it is a safety issue that they knew about.

ABS, service brake system, cruise control failed and no parts available to fix it.

The ABS Brake control module malfunctioned causing several electrical issues. Fortunately the vehicle was able to function. RAM Service center noted a wait time of over 3 months. When I brought the vehicle to another Service center looking to see if the part was available, I was told to make an appointment and they charged me $90 to tell me what I told them. Uggg.

ABS and traction control lights come on intermittently and a chime sound occurs. When this happens cruise control stops working. Getting a “Service Electronic Braking System” message and “Service Antilock Brake System” message. Had to wait three weeks to get an appointment for dealer to troubleshoot. Dealer said it has code C0020-01 logged. Dealer says the Hydraulic Control Unit (HCU) has an internal failure that is shorting out the ABS pump control. Dealer stated that part will not be available until February or March of 2024 if not later for repairs. Dealer verbally said to either park the vehicle until part is available or drive it knowing that the ABS braking system may not work properly in case of emergency stop. Dealer said there is no recall for this problem but they are aware of many vehicles with it. I feel there needs to be an immediate recall issued for this problem as it is endangering the public.

My ABS and Traction control warning lights and Chime continue to come on and off while driving. Replaced the anti brake Hydraulic Brake Controller two years ago and now the same problem. I read that there are quite a few of the same model trucks having the same problem!

My 2018 3500 Dully with 34,000 miles started having an issue with the ABS, Traction Control and Eletronic Brack control systems. While driving the truck on a trip, the Traction Control, and ABS lights started coming on intermittently and the check Eletronic Brack control came on at the same time and it too flashed intermittently. Also, while this is happening, the cruise control does not work. Took the truck to the dealer, parts are not available until February of 2024. Five months from now. They recommend two parts be replaced, Anti-lock brake system, part number 68347098AB and Control Anti-Lock Brake System Part 68143491AB. I'm being told it will cost around $2,000 for the repairs. The 5-year 100,000 drive train is within the warranty period; however, this is not covered by RAM. For such an expensive truck, I find it disturbing that in the event of such failure It was advised to take the truck into the dealer as soon as possible because the truck with an ABS issue is not drivable and the dealer says its ok to drive it even though all the systems lights are flashing intermittently.

ABS and HCU modules are not operating properly. Resulting in no abs and no cruise control.

Abs and traction control lights are on. Cruise control will not work when lights are on. Lights go on and off with chime very annoying. Brakes will not function properly when lights are on. Contacted dealer no eta on parts. Almost 2 years now. Contacted dealer before warranty was out. Next time I went to ask I got another service rep and he said my warranty is out. This is not good.

I am getting a warning on this dash telling me that I need to "service electronic braking system". When this message comes up I lose my ABS brakes, cruise control and I get a traction control warning light. Sometimes this will stay on for weeks and then go off for a day and start all over again. When the road is wet you have to be careful with the brakes. I went to the local dealer in Bryan, TX and showed him the warning lights and he told me that I had a bad sensor in the truck. The cost could be as high as $1500.00. The dealership told me that they repair on an average (2) two trucks a DAY foy this PROBLEM. I had the truck checked for any codes in the system and the tech told me that I did not have any codes but yet the tech could see both warning lights on my dash. ABS light and Traction control light.

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the ABS warning light illuminated, and the cruise control became inoperable. The vehicle was taken to the dealer and the contact was informed that an unknown sensor needed to be replaced; however, the part was not available. The manufacturer was made aware of the failure. The failure mileage was approximately 20,000.

Mileage: 20,000

When driving at Interstate speed of 65 MPH pulling my goose neck horse trailer the instrument panel started dinging and indicated "Service Electronic Brake System", "Service Antilock Brake System" and the Cruise Control stopped working. I slowed and continued home with warring alternation with "dings" every few seconds. I took vehicle to local Dodge Dealer (Blaise Alexander Lewisburg PA) on 08/10/23 who checked the truck and said I needed the HCU replaced. (Code: 0020-01) I had to wait a few days to get the part. Truck was returned to me on 08/15.23. Invoice Number CHCS26809. Total Cost: $843.75

I have a 2018 Dodge 3500 with 9800 miles on it.. The ABS light has come on reflecting a braking and control problem. This also shuts down the safety system within the brakes, shuts down the 4 wheel drive and cruise controls also. It is my understanding from the dealership, there is a problem with the parts within this system, and they can not get any parts released to them for repair. They also don't want to use the same parts, knowing they will only fail again. Which would fall back on them, as a repair faciality. Why hasn't the NHTSA ordered a recall on these vehicles. There are Law Suites also addressing the ABS failure and many complain on this safety failure. I see there is a recall regarding tailgates issue on some of the dodge products. Clearly the braking systems must a higher priority. We should not be required to pay for these repairs. I paid $ 70,000.00 plus for my truck!!! Now they cost in the mid $ 80 K I want feed back from the NHTSA regarding there actions, on the Dodge ABS failure. You ask a question below regarding "WAS THERE A CRASH" in this case it was a near crash. Yes I alive, due to my agility to control the vehicle only. I'm 65 and drive vehicles prior to ABS, so this played into my abilities to control the vehicle. It is now a Federal Law that all vehicles be equipped with a ABS system.. ONE THAT WORKS CORRECTLY. My truck is due a annual safety inspection by the end of this month. Its unsafe to operate my truck, and it must remained park in the garage intil someone stops draging there feet and issue the recall. Yes I am very upset, as with many others

ABS warning light came on, this also shuts down the cruise control system. ABS traction control is inoperable, my understanding the problem is the ABS/HCU pump/Module.. I only have 9087 miles on this truck. It’s a Dodge 3500 Dully. I garage keep and baby this truck, as I paid a lot of money for it. It is my understanding, based on all the internet feedback, that this is a major safety issue and NHTSA is dragging there feet, on ordering a recall.

C0020-01 ABS Pump Motor Control - General Electrical Failure Under Warranty by FCA Extended Warranty Unable to order part until after 2/21/24 Unsafe to drive with issue and cruise control is inoperable Dash continues to beep while driving which is also very distracting

Truck has only 65, 000 miles on it, I’m the second buyer, has never haul anything or hitch a trailer, I’m having this electrical brake system failure ABS, this vehicle is to expensive and new to have early issues on it. ABS Motor Control- General Electric failure. I seem other similar problems reported with same year and same problems.

I recently purchased this 2018 Ram Dually for work on our farm. After 1 trip all the ABS/traction control/4wd and cruise control wont work. It seems that this a safety issue that ram will not address. I would like to file a complaint that if I had known about these issues, I would not have purchased this truck. It is unsafe driving and with no ABS and cruise control or traction control. I depend on the 4wd in our farming business and not having this has caused me lost income because I simply could not get the job done and had to give the job away to others.

On my 2018 RAM 3500 beginning on Memorial Day 2023, the instrument cluster began flashing with a loud door type chime. The cluster began cycling through messages including Service Electronic Braking System, ABS Failure, and illuminating alarms. Upon testing with a code reader I was presented with the following codes: C0020-01 ABS Pump Motor Control - General Electrical Failure and U0402-00 Implausible Data Received from TCM. Upon internet investigation, I discovered this is not an uncommon problem with several hundred reports available on ramforumz.com and other sites. According to several complainants, the repair for this will cost in excess of $2000 with one complainant stating this has had to be repaired twice as the replacement components are also faulty. This needs to be investigated and frankly needs to be a national recall on these vehicles, it is a lot more dangerous than a tailgate lock issue. I am concerned with the cost, but more concerned that replacing the noted components may not solve the issue in the long term resulting in additional costly repairs.

In July 2022 our 2018 RAM 3500 Diesel 4 by 4 truck started having an intermittent alert. Service electronic brake system, ABS, traction control. Cruise control is disabled during this alert. May 2023 the vehicle was taken to local dealer for a diagnostic. They revealed no codes were revealed answer was to replace the ITBM at a cost of 921.00. And the diagnostic charge was 233.00. I tried to contact the dealer for further questions with no cooperation. I started investigating and purchased a code reader at my own cost. The code that showed was C0020-01 ABS Pump Motor Control-Electrical Failure. Much different than the ITBM I was told. Fiat Chrysler Automobiles put out a Case Number: S2005000004 Release Date 04/28/2020 Symptom/Vehicle Issue: C0020-01-ABS PUMP MOTOR CONTROL- GENERAL ELECTRICAL FAILURE Discussion: Basically says to replace HCU first and then ECU if code still active. So, the dealer is aware of the issue and outright lied to me. There is also an active Class Action Lawsuit for this very issue In California Plantiff James Neu. The fact that my vehicle is not in a safe working condition with this faulty part. The fact that the Dealer is lying about which part is defective and would have installed a different part than what they said the problem is. It is very disturbing that an automotive company is treating the safety of their customers so carelessly. The Fact that this is a common and widespread issue and nothing is being done to rectify, appalling. Thousands of vehicles on the road, no parts available. Action needs to be taken. Lives will be lost, severe injury, it can happen to innocent people. Please do something

The ABS and Traction lights intermittently come on and blink non stop. Also, a "Service Antilock Brake System" and a "Service Electronic Braking System " message scrolls through the dashboard screen with an audible alarm. The truck was inspected on September 2nd of 2020 and parts 05400701- Control unit, Brake anti-lock hydraulic and part 68143491AA- Control Antilock Braking System were replaced under the manufactures warranty at 20,457 miles by Arrigo Dodge Chrysler Jeep Ram ID 45724. On May 27th of 2022, once again the same parts failed and dealer ID 58821- Massey- Yardley Dodge Chrysler replaced the failed parts for a second time. The milage on the truck was 60,540 at the time of this repair. The paperwork from the dealer shows an ABS Control Unit Internal Failure. Less than a year later, on May 5, 2023 the parts failed once again (3rd time). I took the truck to dealer ID 58821- Massey- Yardley- Dodge Chrysler for inspection and repair service but I was informed that repairs were not available and that this issue was put on an engineering hold for further review since the parts continue to fail. There is no available timeline for repairs. This lack of response from the manufacturer and the flaw in design creates a safety hazard not only for my family and I but for other drivers around me since the truck breaking response is delayed at times.The truck does not break promptly and the cruise control is cancelled automatically. In addition, the trucks slows down when the message comes on in the dashboard. The problem has been addressed twice by two separate RAM dealers but the issue is not the dealer but manufacturer design. At this time (the third time) there is no solution available to address this ongoing and repetitive defect. The problem has not been resolved. I have attached a copy of all the paperwork and comments from the dealers in case they are needed.

Ram truck was taken to dealer December of 2022 with 7,000 miles due to ABS lights on dash. The dealer Larson Dodge ordered a new part and said they would not be able to complete it until March and to "drive it as it is". The vehicle doesn't have functioning anti lock brakes etc. Now they have told me it will likely be August due to Chrysler being the problem. This is obvious far too long and now I'm out of options.

While driving at any speed the abs and traction control lights start flashing and a chime goes constantly. also when this happens it causes the cruise control to disengage without any warning. Also leaving you without abs brakes. I am on my 3rd abs module and 2nd hydraulic control unit and needing a 3rd hydraulic control unit for this vehicle with less than 62,000 miles the first one went out around 16,000 miles and the second at 37,000 miles. This is also my second truck from this manufacturer to do the exact same thing that happened at 30,000 miles and had another one in the family that did it at 7,000 miles. As i research online I find that this a common occurrence and nothing has been done to resolve the issue other than just replacing the parts with new and wait for it to happen again. I am in need of a new hydraulic control unit and am being told that they are on some kind of hold until the earliest date of August and just to drive the truck with non-working safety equipment.

I have two warning messages appearing on my dash. Service Electronic Braking System and Service ABS System. Took it to my dealership Michiana Chrysler Dodge Jeep Ram FIAT in Mishawaka Indiana. I was informed that it needed an HCU (hydraulic control unit) and that the part was unavailable because of engineering review until at least August 2023. The work order was closed and i was sent on my way and told to check back at a later date for availability. After a little reading i found that this issue is under investigation and i wanted add my truck to your list of reports.

FOR THE LAST 10000 MILES OF THE TOTAL 53K ON THE TRUCK, THE ABS AND ELECTRONIC STABILITY CONTROL LIGHTS TURN ON INTERMITTENTLY AND THE WARNING CHIME SOUNDS. THIS SOMETIMES CONTINUES FOR 1 MILE, SOMETIMES FOR 20 MILES. SOMETIMES IT WILL NOT HAPPEN FOR 50 MILES. IT APPEARS TO HAPPEN MOSTLY ON ROUGH HIGHWAYS OR CITY ROADS. HAPPENS AT 3 MPH AND AT 75 MPH. WITH ABS AND ESC DISCONNECTED IT IS EXTREMELY HAZARDOUS TOWING MY NORMAL 16000 LB TRAILER, ESPECIALLY ON WET OR SNOWY ROADS. I HAVE NO OTHER VEHICLE. IF ABS IS REQUIRED ON US HIGHWAY VEHICLES FOR SAFETY REASONS, HOW CAN THIS NOT BE A SAFETY ISSUE? IF 2019-2022 RAM 3500 TRUCKS ARE UNDER A RECALL FOR THIS SAME ISSUE, WHY IS 2018 NOT? RAWLEY CDJR IN SIERRA VISTA AZ HAS VERIFIED THE ISSUE AND RECOMMENDED REPLACING THE HCU AND ABS MODULE, BUT IS NOT ABLE TO GET THE PARTS. THEY SAY POSSIBLY IN AUGUST. THEY HAVE OFFERED TO REFUND MY PAYMENT FOR THE PARTS THEY ORDERED AND TO DISABLE THE TRULY MADDENING CONSTANT WARNING CHIME TO SAVE MY SANITY. THEN MY TRUCK WILL NOT HAVE ABS OR ESC OR CRUISE CONTROL AT ANY TIME. IS THAT SAFE? THIS SAME ISSUE IS WELL DOCUMENTED AT NHTSA BY MANY OWNERS. IT APPEARS TO BE TIME TO START COMPLAINING TO OUR CONGRESSIONAL REPS.

Service Anti-lock brake and Service electronic braking errors come up on screen at random, sometimes the lights will stay one and cruise control is disabled. While braking they seem to shudder. Not safe for a Heavy duty truck that is able to tow 15k lbs.

Electronic Braking System and Antilock Braking System is defective, similar to being described in FCA Case Number S2005000004. This issue also effects the Speed Control System

Experienced a failure of the ABS Control Module and Electronic Traction Control during a light snow storm in September of 2022. Dash warning lights come on and go off intermittently. When warning lights come on and cruise control is being used, cruise control is deactivated. Dealership confirmed ABS CPU failure on 11/17/2022. Still waiting on replacement parts and are projected to be in around 4/18/2023. Warning lights continue to come on and go off intermittently. Never know how long cruise control will work before deactivated by warning lights for ABS service light and Electronic Traction Control coming back on.

The contact owns a 2018 Ram 3500. The contact stated while driving approximately 70-75 MPH with the cruise control engaged, the cruise control independently deactivated and the vehicle decelerated. The “Service ABS” message was displayed. The contact continued to drive and after driving over a bump in the roadway, there was a dinging sound detected and the message disappeared. The contact called the local dealer, and the vehicle was taken to be diagnosed. The contact was informed that the ABS pump needed to be replaced; however, the part was not available. The vehicle was not repaired. The manufacturer was contacted, and the contact was referred to the local dealer for assistance. The approximate failure mileage was 17,593.

Mileage: 17,593

NOTE: 11/18/22 filed a complaint with NHTSA - they will share it with manufacturer case number(ODI) - 11494143 QUESTION: What component or system failed or malfunctioned, and is it available for inspection upon request? ANSWER: ABS module problem Code : c0020-01 service electronic brake system Service Antilock brake system The display indicators for all of these systems come on intermittently. They effect the use of the cruise control as well. QUESTION: How was your safety or the safety of others put at risk? ANSWER: There is always the potential that any or all of these systems can fail at any moment when I am on the road driving; especially with 18k-20k pounds of load behind me. QUESTION: Has the problem been reproduced or confirmed by a dealer or independent service center? ANSWER: Yes. Galleria Tire Center in Pelham, Al. confirmed the display of all these warnings and also provide me with the code that I posted above on first question. QUESTION: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? ANSWER: NO QUESTION: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? ANSWER: warning lamps come on intermittently and stay of for random times. Always wondering if one of the systems are going to fail. We pull an 18k RV with this truck and it would be tragic if we have a system failure that results in an accident. Online posts also verify that many other RAM owners are experiencing the same problem with their trucks. This most certainly needs to have a recall on it. Very dangerous. Manufacturer has great liability and litigation exposure if they do not act on this and accidents happen. They have been warned.

1. ABS pump failure, stable tract for steering. Available for inspection if requested. When this warning light comes on cruise control will not function. 2. If ABS failure cannot slow down in a timely manner danger to occupants. 3. Yes 4. Unknown 5. Yes, warning lamps appeared at 15,000 miles. Would like to see this be a recall because numerous other owners have this same issue.

ABS Control Module and/or Wheel Speed Sensors is causing the abs warning light and traction control module light to go on and off intermittently for over a year causing the cruise control to not engage or to disengage…

The warning chirp occurred and the ABS and ESC lights came on the first two times. The incident happened so quickly I could not clearly determine which warning lights illuminated. On April 18 with just over 39,000 miles on the vehicle the chirping alarm and the ABS and ESC light illuminated. In addition two warnings appeared in the dash: "Service Antilock Brake System" and "Service Electronic Braking System." The warnings happened multiple times per minute in some cases. Other times the vehicle would go for many miles without the warning. Every time the warning chirp was heard the cruise control would disengage. I did not notice any problems with the brakes of the truck. In researching the issue I learned that many people are having this problem. I contacted Ram and they directed me to a dealer who diagnosed the C0020-01 fault code and that the hydraulic control unit (HCU) for the ABS system was defective. According the the TSB Ram has put out about the issue the ABS module could also be bad, but the first part of the repair it to replace the HCU and if the problem persists to then replace the ABS module. Ram apparently has an inconsistent level of support for owners experiencing this malfunction with some getting the repair done out of warranty, while others have to pay for the repair. Because it is brake related it seems this should be an item replaced as a safety issue, no matter what the mileage on the vehicle.

The abs system has failed on my truck and many more possibly by a dealer defect and no recall as of now. When the abs warning light comes on it also puts up a warning light for the electronic braking system and you aren’t allowed after that to set the cruise. Anytime you hit a bump or turn the wheels or just randomly at any given time the lights come up on the dash and it chimes which will drive anyone nuts. With the electronic braking system not functioning properly could potentially lock the brakes up on the truck in my opinion knowing how it functions. Which in my opinion is a safety hazard. Also I might add that taking my vehicle to my local dealership is a complete waste of time as the diesel mechanic up there is terrible at his job. He has misdiagnosed two of my trucks and I believe he had something to do with a transmission going out in one. He “fixed” it then 3000 miles later the transmission completely destroyed itself which made me have to trade the truck in. Also the traction control system does not function when the abs light is on. In doing research I have found many many people with this same problem.
