I purchased my truck in March of 2024 with an undisclosed problem from a dealership in Texas. I contacted them two weeks after it began and they said they couldn't do anything as is the greatest business disappointment of American commerce when used vehicles are purchased under the "As Is" clause. The undisclosed problem is this, my truck loses acceleration power for up to 20 seconds in dangerous situations when I attempt to increase speed from a stop or slower speeds and the truck doesn't shift to accelerate to reasonable speeds. This situation happens each time I drive this truck. The scarier situations happen when changing lanes, turning left, or right, or making U-turns. Each of these conditions threatens safety every time this happens, but more so when there is fast-moving traffic coming behind after changing lanes or if on-coming traffic approaches my now power-less truck when making a left/u-turn. My local dealership shop found the CBF drum in the transmission to be faulty causing internal leaks which fail to engage the gearing system. The repair cost to make my truck safe again is over $7.2k. If this truly is a safety failure problem, I request NHTSA for payment to my dealer or reimbursement, please.

Many times I have experienced a delay in acceleration or where it fails to accelerate relative to the pedal position and will then suddenly aggressively accelerate. This has resulted in me almost being hit in traffic due to the lack of power output leaving me panicked as vehicles barrel down on me while I’m stuck waiting for the truck to get the signal to accelerate. The issue has begun to occur more often but is spontaneous when it occurs leaving me with huge trust issues with the vehicle not knowing when it will decide if it wants to output power or not. It occurs most often after the vehicle has been sitting unused, like first thing in the morning or after work when it has been sitting for hours, and most often when executing a turn from either a slow roll or a stop. Meaning if I’m on a side street and wish to pull out into traffic, it will just decide not to accelerate and leave me sitting in the road as vehicles approach scaring me into pumping the throttle or attempting to push it to the floor in the hopes it gets the signal and will accelerate to get me out of harms way. It’s a huge issue and I’m worried it will result in an accident. I’ve also seen many other are experiencing the problem. I have an appointment with my local ford dealership to have it looked at but I’m worried they won’t be able to replicate the issue and will leave me with no answers or help.

10 speed transmission has started shifting hard at times and is random when it occurs. At times the hard shift comes with some stuttering under normal acceleration.

The contact owns a 2021 Ford F-150. The contact stated while driving 60 MPH, the transmission independently shifted to neutral, and the vehicle decelerated. In addition, the power train failure warning light illuminated. The contact stated that within several seconds, the vehicle returned to normal speed, and the power train failure warning light was no longer illuminated. The contact stated that the failure occurred while driving on a major highway. The vehicle was taken to the dealer where it was diagnosed with an external transmission failure. The contact was informed that the transmission needed to be replaced, and the software needed an update. The vehicle was not repaired. The contact was informed of an unknown recall however, the VIN was not included in the recall. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 79,000.

Multitude of transmission problems, Have smelt clutches in the transmission burning very strongly twice now. Hard shifting up shifting and downshifting. Slamming into gear almost locking up the back wheels. Has failed to move with transmission binding up putting it in reverse. Multiple slippages and different gears. After the truck is stopped at a light for 10 to 30 seconds there will be a hard clacking sound and the transmission that can be felt in the floor. Extreme hesitation almost causing an accident pulling out into traffic. Check engine light one time for faulty Park solenoid and the vehicle would not come out of park. Disconnected and reconnected the batteries. Cleared the code and finally got it to come out of park. The code cleared after 3 days. Was working with the dealership over the phone remotely at the time with it. They said it disappeared and they didn't know why. Transmission has been flushed at 50,000 miles by ford dealership. Ford dealership has done a reprogramming on it so far. Transmission still had problems had a Ford take a ride with me. He stated that it need to be rebuilt or replaced. Ford dealer is dragging their feet to do anything. I have many text messages into the service writer updating him of new problems and current problems as they occur. They are fully well aware of the issues. I drive a lot like 6,000 miles a month and I think they just don't want me put miles on their loaner vehicles for their faulty transmission problems. I purchased the vehicle in February 2024 problems have been occurring since purchase.

The contact owns a 2021 Ford F-150. The contact received notification of NHTSA Campaign Number: 23V896000 (POWER TRAIN); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

When turning right there was a complete loss of power with no response from the throttle it was just stuck coasting at 20klm hr. For 20 seconds or so then throttle kicked in and normal operation again. This has happened twice now in the past week. Very dangerous especially when turning into traffic.

Despite having been told my truck was fixed at a dealer shop, my truck still displays an absence of forward propulsion when applying the gas pedal and trying to accelerate from slower speeds. This has happened when trying to make a left or right turn when there is oncoming traffic. Sometimes this happens while trying to accelerate on the on-ramp of a highway to get up to normal piste speed limits with traffic very fast behind me. The dealer I took it to said they fixed the issues. Luckily I can apply the Manual mode with a button, but this is distracting when trying to look for the button, and the issue comes back in Automatic mode.

The vehicle fails to acclerate. When pulling out into a street the vehicles accelerator became completely unresponsive. The vehicle was stuck in 2nd gear going about 8mph and the vehicle would not accelerate, I even push the pedal all the way to the floor for several seconds with no response. I had to come to a complete stop in the middle of the street for the truck become responsive to my inputs. I was nearly rear-ended due to this issue.

Vehicle regularly loses all throttle response for 5-10 seconds, usually around corners at low speed, but sometimes while driving straight. This lack of response is alarming when pulling into traffic. There is no light on the dash indicating traction control is activated.

Leaving a parking lot and after turning right, the truck failed to accelerate for over 800 feet. Over this distance, the accelerator was pressed all the way to the floor and the truck stayed stuck in 2nd gear, slowly increasing from 2,000 rpm to 2,500 rpm, and from 17mph to 21mph. After this time, the accelerator pedal was pumped, and the truck responded with normal acceleration. This is not the first time this truck has had the issue, but it is sporadic, and almost always when turning right from a rolling stop. This has a high potential of causing accidents when trying to turn on to a road with higher speed traffic and unable to accelerate as expected. There were no warning lamps or messages indicating an issue with the vehicle. The issue is not consistently reproducible for Ford to inspect it, but it does happen a few times a month.

I just want to provide support for others that have this safety issue, as my 2021 F150 Powerboost also has this issue. When making a turn, usually a righthand turn, onto a busy road, the vehicle will fail to accelerate. The delay is not turbo lag, but more so a dead space or lag of any response from the power train. I have found that if I disable the advance trac and traction control, the issue is no longer present. Just wanted to reinforce the confidence at the start and how dangerous it is. You get this false sense of security that the truck is going to accelerate a certain way, then falls flat at a very risky time. FYI, I am running the latest PCM code and modules updates available from Ford, via FDRS. Here are other examples if it helps: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When accelerating from a low speed, accelerator does not respond.

After a few hours of parking in a lot, or overnight from my garage I lose accelerator response when trying to accelerate. I will lightly use the throttle to pull out of a stop, turning right, and the truck will not accelerate for up to 12 seconds even with steady throttle input or pumping the throttle. If I press the accelerator to the floor it will shorten the delay time, but will surge at full throttle. Twice I have pulled into traffic, but truck will not accelerate and I am almost rear ended or cannot cross an intersection with traffic come at me. This is a serious safety issue. Dealer has not been able to replicate or repair. This has been happening for 6+ months.

After a right turn in a residential street, I pressed the accelerator to progress on the roadway. The truck did not accelerate, so I looked at the tachometer and observed it above 0 and below 1,000 rpm. The engine was running, but unresponsive despite pumping the accelerator. While rolling at 5 mph I shifted the transmission to neutral and continued pumping the accelerator. There was no response for the next 200'. Finally, the engine became responsive and ran normally. It runs normally now. I cannot reproduce this issue. I called the Ford dealer service on 8 November 24 at Noon and they said "watch for the issue". I expressed that in traffic, a suddenly undependable engine is a serious concern. The accelerator/engine was unresponsive for a continued period of time. The gas engine was in control. There was no check light/warning light. The Ford dealer inspected the telemetry of the vehicle remotely and no anamolies were observed. The dealer declined to inspect the vehicle since the issue is not reproducible.

When gearshift lever is in "DRIVE," it would not shift into "REVERSE" or "PARK." There were no warning lights. Gearshift lever would always move from "PARK" to "DRIVE" or "PARK" to "REVERSE." I was in traffic, I was unable to move the gearshift from "DRIVE" to "REVERSE" when I needed to backup. The only way to get the gearshift lever to move was to TURN OFF the vehicle while it was in "DRIVE" and on a 2021 F150, the gearshift lever will automatically move into "PARK." Then I was able to restart the vehicle and move the gearshift lever into "REVERSE." From "REVERSE" the gearshift lever would move into the "DRIVE" position. This failure resulted in my inability to control my vehicle when required. The dealership replaced a GEAR SHIFT ASSEMBLY to resolve the problem.

1) Vehicle acceleration delays. From a stopped vehicle condition transitioning onto highway roadway the vehicle failed to accelerate for several seconds. Again from stopped or low speed idling condition following a turn there occurs a 1 to 10 second failure to accelerate. 2) Failure to accelerate puts into question the safety of anyone in any vehicle within proximity to the malfunctioning vehicle. 3) Our personal vehicle problems has not been observed by any dealer, we have not presented it for diagnosis at this time. We are actively monitoring and posting to the [XXX] group about our experience. A ford dealership employee has an advanced Ford factory representative working on understanding the problem. Otherwise, it seems, no one currently understands the issue as yet. 4) Our personal vehicle has NOT been inspected by the Manufacturer, police, insurance reps or others at this point in time. 5) There has never been a warning lamp or message in regard to this acceleration failure. The failure is not predictable in nature. We have never experience such failure at highway traffic speeds. It most often presents when accelerating from an idle or low speed driving condition, often following a turn.

When attempting to accelerate the vehicle hesitates for several seconds as the automatic 10 speed transmission attempts to engage the proper gear. This is intermittent. It has happened numerous times and is particularly dangerous when attempting to merge onto a highway or turning in either direction at an intersection.

The truck is a 10-speed and the 10 gears are displayed on the dash. While driving down the road, the gears start to disappear. Once it gets to the gear you are in, it will force a hard downshift. It will continue to force a downshift into first gear and the truck stops with hard engine breaking. The first time (6/26/2024), I was almost rear ended. If you put the truck into neutral, all gears reappear and you can start to drive again without any indication of transmission issues until the gears start to disappear. Ford dealership has attempted to fix multiple times, but continues to happen. If not expecting, is very sudden and can cause rear-end collision or loss of control. I have a detailed record of the incidents (date, speed, mileage, etc.) as well as multiple videos demonstrating the issue. Not able to upload videos.

Check engine light on . Ford says exhaust heat exchanger bypass valve. I see online multiple people are having the same issue . Seems to be a common issue with this vehicle . They are saying it’s not a part of the power train warranty although it’s attached to the power train . This is a safety issue. With the amount of posts about this issue I’m surprised it isn’t a recall already.

The contact owns a 2021 Ford F-150. The contact received notification of NHTSA Campaign Number: 23V896000 (Power Train); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. VIN tool confirms parts not available.

While operating the vehicle, I shifted into park, using the console shifter. With no warning, the vehicle malfunctioned. The console shifter indicator light started blinking next to the "P" and it would not let me shift back into gear. I turned off the vehicle and tried to restart it in the hopes that it would clear the error. The vehicle engine would not start, and told me to shift the vehicle into park. I was unable to shift the gear into park or any gear. A tow truck driver came and we were able to force the vehicle into neutral for towing, but the vehicle's parking brake engaged and would not disengage. Every time we turned off the parking brake, it immediately turned itself back on. Thus, we could not push the vehicle into a better position for the tow truck to get the vehicle and the tow truck operator had to drag the vehicle with its back tires not turning. At the Ford dealership, a service employee inspected the vehicle and said there was no physical damage to any component and that some kind of electronics error had caused the fault. He said it was a known issue with F150 transmissions and that a Ford service bulletin indicated a 6-hour "module" reprogramming process was necessary to make the truck operable. He said that it could recur. I spoke to Ford customer service. A representative there confirmed that this is a known issue with F150 transmissions but that no recall had been made. She also stated that Ford did not know why it happens and that, even after being "reprogrammed", it could happen again. Based on my experience and discussions with Ford, the F150 can suddenly become inoperable and (because of the parking brake) immovable. Thankfully, the transmission error occurred for me in a safe location near my home. It could have been very dangerous had the vehicle become immovable in an unsafe location or far from home or help. I am concerned it will happen again. The vehicle is currently at the Ford dealership in Grand Ledge, MI.

At a stop, in electric mode, truck will lunge forward as if you were rear ended. Most of the time, transmission failure will occur after some time due to this lunging forward, and it has happened to many truck owners. Electric auxiliary transmission pump tends to be the cause .

There hasn't been an incident yet. But, I want a record of this somewhere. I'm assuming there may be an incident in the future; and, I'm concerned about that. Either an incident with my truck or an incident with the 100s of thousands of Ford and Lincoln vehicles from 2017-2023 that have this issue. The issue is Ford SSM 51939 - a whining noise coming from the bellhousing and the front of the transmission fluid pan. I have taken my truck to a dealership. I have called Ford about this. I have researched extensively online. I have called NHTSA. I have emailed the Office of Vehicle Safety Compliance. I am now filing this report online. The safety issue? For me, I'm now having to wear EARPLUGS when driving my vehicle. For others, they have been told to turn up the radio. I am now hearing the noise all the time -- believe it or not, even sometimes when I'm not even in my truck. Ford needs to address this. They send me to you. I don't have the 'option' of TRADING IN MY VEHICLE...others don't either. What am I to do? When something serious happens because people are remedying this themselves...it will be a very sad day. But, maybe only then will Ford do something. I don't know what else to do other than call Ford everyday, and email every agency that may be able to apply some pressure. Sadly, I have a full-time job...and this is really frustrating for me, in more ways that one. Hope you have a nice day!

If you pull onto a road and try to accelerate, the vehicle is unresponsive. The RPMs will increase, yet the vehicle drive train (10 Speed Transmission) is unresponsive for several seconds. This has been an ongoing issue with the vehicle since new and was first reported to Ford Customer service on Jan 2022. Ford has made several attempts to fix this issue, yet the transmission continues to fail with the same issue. This is a critical safety issue that jeopardizes the passengers in the vehicle. Vehicle parking brake engages without notice. At any given time, the electronic parking brake engages without warning and you have to manually release. While sitting at a controlled intersection, on an inclined street, waiting for traffic light to change, with vehicle in Drive, foot on the brake, the electric parking brake engaged. Vehicle shift lever moved to the park position on its own. Vehicle engages it's parking brake and moves shift lever into Park while sitting in traffic is very dangerous. Vehicle shift column failed in drive and vehicle would not move or run. This caused drive train to lock in place, freezing all four tires. Ford had to drag truck onto flat bed with tires locked. It had to be dragged off flatbed when delivered to Ford dealer for repair. They had to put grease down on the flatbed so truck would slide off without tires rolling. While at the dealership, the mechanic had to manually disconnect the calipers in order to move vehicle. The safety backup features failed and would not release wheels (lever under steering column).

My 2021 F-150 Powerboost randomly shuts down on the highway and while pulling out into traffic. When it shuts down the steering and brakes work but the engine is off/no acceleration and the truck displays a warning telling me to "Stop Safely Now". Truck has been look at many times by Ford and every time they give it back to me it happens again. There appears to be either and electrical or software issue but after 3 months Ford doesn't seem to know what's wrong with the truck even though they have reproduced the problem. It has happened over 20 times putting me and my family at risk of getting in an accident.

3.6.2021 - Ford F150 purchased at Battlefield Ford (Ourisman Ford), Manassus VA / registered in CT 7.27.21 – inspected by Torrington Ford, Torrington CT for rubbing sound front left side, nothing found / 6,325 miles 2.10.22 – inspected for same issue / nothing found / 16,000 miles 7.27.22 – inspected for same issue / nothing found / 24,000 miles 12.24.2022 – “Catastrophic failure” of front differential / 34,369 miles. On Christmas Eve 2022 myself, husband and son were driving to family in NY when the truck very quickly started to make a severe grinding sound, became unable to steer, loss of control, and started to produce smoke & fire under the hood. We immediately stopped and got out unharmed. Fire was dripping out of the bottom of the truck and smoke/fire under the hood. We were lucky. Firetrucks came but were unable to do anything. The truck's wheels completely seized up - the tow truck had to skid it onto the flatbed. Repaired at Simmons-Rockwell Ford, Hallstead, PA. Complete new front differential and damaged parts in proximity to the failure (pinion gear, axle shaft, etc). 12.16.2023 – Again hearing a sound in front left side while driving; bring to the shop for inspection. Shop confirms front differential is failing again, per Torrington Ford, (where all maintenance and repairs were completed, except for the first failed front differential in PA). Advise not to drive for safety reasons. 52,922 miles. With both front differential failures - no warning lights or messages. Symptoms - a slight rubbing/grinding noise in the front left side of vehicle; “rough” sound while driving. 1st front differential – inspected at 6,000 miles, 16,000 miles, and 24,000 miles. Failed at 34,369 miles. 2nd front differential – inspected at 52,922 miles, failing differential, advised not to drive. Dec 2023 – Buy-back claim filed with Ford Motor Co. Denied - "outside of the 18-month warranty period for VA Lemon Law". Clearly, safety is not a guiding tenet for Ford Motor Co.

On November 29, 2023 I took my 2021 F150 to Larry Miller Ford for servicing and repairs related to Recalls 22S71 and 23S35. When the tech was rotating the wheels he discovered that the axle shaft bolts were sheered off on both the left and right rear wheels. The service manager called to tell me that this was a serious safety issue and that only the brake rotors were preventing the wheels from falling off the truck. The service manager told me there was a "Customer Satisfaction Program 22B34" issued by Ford, but no Ford Recall relating to the problem. Larry Miller Ford has replaced both axles and axle bolts. I am waiting to find out if there is damage to the rotors, calipers or brake pads, a concern since the sheered off bolts were rattling around within that area since breaking off apparently between service visits. I strongly believe Ford should be required to issue a recall on this problem. I never received a notification on CSP 22B34. Had it not been for my tire rotation, the wheels could have fallen off at highway speed.

I heard a scratchy rattling sound around 35-36k miles at very low speeds. Eventually narrowed it down to the passenger rear wheel area. I took off the wheel to inspect the area and the head of the axle bolt fell out. It looked to have been yielded from over torquing or something. But I was shocked! I have no idea the actual period of failure. If I hadn’t rolled my windows down for the nice weather, I probably wouldn’t have heard it. I checked and there has been no recall or anything sent to me that this is a problem. I tow a camper with the family and if the axle failed while doing so, it could of killed us. Very unhappy that Ford has not recalled this. There are many others on a Facebook group that have had the same issue. It needs to be Remedied.

Vehicle came to complete stop in traffic with warning light "stop vehicle" would not restart. Taken to dealership. Dealership replaced ecu and some switches to power bank and wiring harness behind headlight. Vehicle was returned 1 week later Drove it 2 days later for 10 miles same thing happened, Ford towed it to another dealership where they cleared codes, and they said they can't replicate, Vehicle was returned after a week. 2 days later I drove yo work and again iy happened stopped in middle of road blocking traffic. Was towed by Ford to dealership where they found over 20 codes, said they can't fix. Ford and selling dealer towed to selling dealer, where they cleared codes and said they can't replicate. I refused yo take Vehicle on fear of getting in severe crash when Vehicle stalls and dies in heavy traffic again. I signed title and sent it to selling dealer, they told me that fordwill not let them buy it back. Do I don't have my money or a truck now

My truck has the Maximun payload axle upgrade. The axle bolts on the end of the shaft have broken. I first notice squealing sound of metal from rear of truck. I searched on line for the symptom and found the problem. I then removed passenger rear wheel to verify broken bolt. I took my truck for service to Morries Grand Ledge Ford in Michigan. They verified the problem, told me it was not safe to drive and have ordered parts. They also informed me that the defective axle is not covered by recall on my vehicle. The service representative did confirm that there are recalls for the same axle but not my vehicle.

Transmission is not working correctly. When truck comes to stop, after 3 second there is a strong jolt that feels like the vehicle is being rear-ended. Error code indicates Auxiliary Transmission Oil Pump. Other owners have had same problem and it was Auxiliary Transmission Oil Pump. Dangerous condition because could cause issue at intersections or hitting pedestrian or other vehicle. Part is apparently backordered so cannot even be fixed.

In the last year I have taken my F150 powerboost in Autonation Ford Orange Park in Jacksonville, Florida twice for recalls. For recall NHTSA # 22S26/22V250 the service department said they were ordering parts and would contact me when they arrived. Never contacted me, even after follow ups. I have recently taken my there for recall NHTSA 23S35/23V509. They have not contacted me.

- The component that has failed is the right rear axle and retaining bolt (the axle retaining bolt sheared off). The vehicle is currently at the dealership (The Ford Store San Leandro, in San Leandro, CA) waiting for replacement parts. Unknown if the vehicle is available for inspection. -To my knowledge my safety was not at risk, but the vehicle is being retained by the dealership because it is deemed a safety concern. -The broken axle bolt was found by the dealership when they were investigating a noise complaint. -The only symptom that was present was noise.

Gear shift lever jammed in reverse and could not be changed. With battery powered motor, the vehicle could possibly take off and cause damage or injury. Vehicle is new and still under warranty. Dealership is evaluating the problem

The driver's side rear axle bolt sheared off over the course of normal driving. Ford is aware of this problem, advises to not use/drive the vehicle, yet no recall has been issued. Without a recall, getting this issue fixed will take weeks/months and Ford should pay for a rental vehicle since this is clearly a manufacturing defect.

The contact owns a 2021 Ford F-150. The contact stated that while driving at an undisclosed speed, he heard an abnormal scraping sound coming from the rear driver's side of the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the driver's and passenger's side rear axle bolts had sheared off. The vehicle was repaired, but the failure reoccurred. After investigating the failure, the contact related it to Customer Satisfaction Program: 22B34, but the vehicle was not included. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 20,000.

Rear axle bolt broke off

This is the 4th time since purchasing the truck that this event has happened with time having the most severe results. When shifting from reverse to park the shifter goes into park and jumps back into reverse. First event (after exiting the truck) the truck rolled into a shipping dock breaking a taillight and buckling the rear bumper. Next two I had one foot on running board and one foot in the truck ant was able to hit the brake stopping the truck. This fourth event one foot was on the running board and one on the ground. As truck went back the door flattened me to the ground and the front tires rolled over both of my legs. The truck rolled up an inclined parking lot, across a busy road and down a bank. I was driven by ambulance to the hospital and then transferred and airlifted to trauma center at Ruby Memorial Hospital. After the second event the local Ford dealer said they could not duplicate the event. The brakes do not hold even though they are depressed and set when the shifter is shifted.

The axle bolt on both rear wheel hubs has sheared about 1/2 inch down the bolt. This led to the gradual loss of power to the effected wheel hub causing unpredictable handling characteristics as the interface between the axle and the wheel hub degrades due to the fastener being sheared off.

The axle retaining bolt that retains the floating axle to the hub failed and resulted in the floating axle splines at the hub failing. This is a known issue (see Ford Customer Satisfaction Program 22B34) but the recall only applies to vehicles manufactured from May 1st, 2021 to September 30th, 2021. My vehicle had the exact failure described by the recall (including the tell-tale ticking sound before failure). However, the build date for my vehicle is March 17th, 2021. Clearly the recall should be on trucks earlier than the May 1 date. The truck was built at the Dearborn Plant. I am assuming the other axle suffers from the same issue and will also fail.

The contact owns a 2021 Ford F-150. The contact stated while driving in electric mode at an unknown speed, while depressing the accelerator pedal, the vehicle failed to accelerate with the transmission in 8th gear. The contact stated no warning light was illuminated. The contact depressed the brake pedal, and the vehicle made an abnormal noise and shifted into 1st gear independently. The contact stated he had experienced the failure 5 times within 2 months. The vehicle was not diagnosed or repaired. A dealer was not contacted. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 22V188000 (Power Train) however, the VIN was not included. The manufacturer had not been informed of the failure. The failure mileage was approximately 61,800.

Mileage: 61,800

Intermittent squeaking noise upon brake tip-in started at about 17,000 miles but performance seemingly unaffected. Then at 21,000 miles noises from became louder and prevalent at acceleration and braking. Noticed issue on Ford F150 14th Generation online forum about axle bolts shearing particularly for those vehicles with Max Tow package and that there was a Customer Satisfcation Program 22B34 to deal with the problem. Inspected hubs and found bolts sheared on both sides. Truck at dealer for warranty repair under the CSP.

The rear rotor/axle bolt was found to be sheered off; the bolt head was located within the hub simply rattling around loose. There is no warning outside of someone possibly hearing the bolt head rattling in the hub as the truck passes by. Thankfully, someone heard mine; otherwise, I would have had no idea the problem existed. This issue has been reported numerous times in multiple online forums, apparently on trucks equipped with the power boost and max towing, and poses an extremely dangerous hazard to the occupants of the truck and to all others on the road. A family member with a similar truck (same model and year) has already had their rear axle assemblies replaced three times (twice on one side and once on the other)!

The 10 speed transmission shifts erratically on both the up shift and down shift sometimes as much as 3 gears and the electric motor interface is also rough and I’m afraid it’s going to self destruct while driving on the highway leading to an accident

(June 14, 2023) While traveling at 55mph the vehicle suddenly accelerated for about 2-3 seconds and several dashboard lights turned on and flashed not available. (ABS, Traction control, Blinds Spot, pre-collision) I safely pulled over turned the truck off, waited a few seconds. Turned the truck back on, and ABS light was solid on the dashboard. I drove another 15 miles stopped again, and when I restarted the check engine light remained solid. After inspecting the truck, I found gear oil leaking from the right rear tire. I removed the plastic hub cap and discovered sheared off axle bolt. Truck was delivered to dealer for repair.

Jerking when accelerating and shifting, when this occurs vehicle has a harsh movement forward then there is a delayed response when trying to accelerate have been multiple occasions where I go to make a turn and vehicle doesn’t respond or stopping in the middle of a turn almost causing my vehicle to be tboned

the bolt connecting the drive shaft to the hub has broken off

After coming to a complete stop the truck violently lurch’s forward. To the point that it feels as if another vehicle has contacted the rear of the vehicle. This seems to be attributed to an auxiliary pump failure.

Rear axle hub bolt sheared of passenger side of vehicle.

The passenger side rear axle bolt sheared off. Safety was put as risk because there was no longer anything holding the axle in place. The problem was confirmed by the dealer, who replaced the axle.

Axle bolt broke

This problem has been ongoing, happening nonstop up to multiple times daily since Feb of 2022 and has spent now 70 days at the dealership in search of the issue. Luckily, the vehicle has not caused an incident yet, but I am afraid to drive it if I get it back from the dealer again as the issue has just gotten worse. The vehicle randomly while driving goes into a "limp mode" in which 1 of 2 things happens. 1) If unable to pull over immediately, the vehicle has very erratic throttle control and 2) the vehicle sometimes gives a warning about the "adavancetrack" system and will sometimes shift itself into neutral out of nowhere forcing you to coast to a stop no matter where or what type of street you are on. In researching this problem to help my dealer at first and now to try and protect myself while in a battle with ford, it seems to be a common problem discussed on many forums on the internet and facebook and seems quite common among the F-150 powerboost. Ford is refusing me a buyback at this time and ignoring the safety implications that my vehicle is having

Complete loss of the throttle while in an intersection. Was able to shut down vehicle, then wait about 30 seconds, then turn it back on clears issue. This has happened at least three times

Both rear axle retaining bolts snapped. The only thing holding the axles in was the brake rotors and calipers. Had they not started squeaking and grinding, I would not have known those critical bolts had broken! At the dealership now being repaired. With the same faulty methods and parts. VERY common problem for the F150 Powerboost with the Max-Tow package.

POWERTRAIN MALFUNCTION / REDUCED POWER Error

Rear Axel Bolt Failure. Please help. This has been an issue for over a year with newer F150s. Most failures occur on the "Max Trailer Tow Packages" with the "floating rear axel". You'll see multiple failures on new trucks. Mine has ~18k miles. Dealer says it's unsafe to drive. Many are finding broken bolts incidentally when getting tires rotated. Others like myself hear it rattling. Someone will get hurt. I have a rental car provided by ford because it's deemed unsafe.

Passenger side rear axle bolt failure. The bolt sheared off completely and was found rattling inside the center cap. Dealer states vehicle cannot be driven. Ford will provide rental until repaired but can’t provide estimated repair date.

While traveling at around 70 mph, the truck felt like it losing power. As I further step on the accelerator, the truck didn't response. The truck then jerked and shifted to gear 9 and jerk again then shifted back to gear 10. This happen for about 10 to 15 minutes and back to normal. During this time the truck loss the ability to accelerate. This happen during the cruise control engaged and also happen without the cruise control engaged. When this happen, the truck had about 35,000 miles and it happened during a road trip from Southern California to Flagstaff, AZ. The problem also happened on the way home. The problem was not observed as the truck travel at 65 mph or less.

I have now had BOTH sides of my rear axle bolts shear off. Both times discovered while rotating tires, the head of the axle bolts were completely broken off

Passenger rear axle bolt sheared off at 13,3xx miled# now the dri ers side axle bolt sheared off at 18,288 miles.

My truck has had its rear axle bolts shear off in two separate occasions rendering the vehicle unsafe to drive.

The contact owns a 2021 Ford F-150. The contact stated while driving from a complete stop, the vehicle hesitated to respond and made an abnormal banging sound while responding. There was no warning light illuminated. Additionally, the contact stated that the transmission was slipping while driving. The vehicle was taken to the dealer where the failure could not be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 17,900.

Mileage: 17,900

Rear axle bolt has sheared off numerous times with no resolution. Ford just replaces the bolt with a new one.

2021 Ford F-150 PowerBoost Lariat, 3.5 V6, with Max Tow package - right rear axle bolt sheared off at about 11,000 miles. Cause to look included squeaky/screeching sound in right rear on both braking and with acceleration. Upon removing center wheel cap discovered axle bolt had sheared off and was simply sitting in the cavity of the center wheel cap.

Sheared right rear axle bolt.

My 2021 Powerboost F-150s experienced an issue where the truck lurched forward as if hit from behind after coming to a stop. This can result in the truck hitting the vehicle in front of you if you are in tight traffic. I dropped the truck at the local Ford dealer and was told it will take 1 to 3 months to fix the vehicle due to part in back order.

Rear Rotor/Axle Bolt Sheared. Truck not drivable. Dealers in area can't look at truck for at least a month and saying shouldn't drive it either. They won't order parts unless I tow truck to them. I'm having the same issue as posted in these threads and various FB posts too. https://www.f150forum.com/f129/2021-powerboost-rear-rotor-axle-bolt-sheared-515460/ & https://www.f150gen14.com/forum/threads/f150-powerboost-axle-bolt-sheared-off.10392/

I heard a very loud screeching noise around 4K miles and took it to the dealership, they said my axle nut on the driver side of the truck was sheared off. They said it was covered under warranty and repaired the issue. 8k miles after repair it is doing the exact same thing. No check engine lights for this issue ever appeared on the dash. Ford spend about 3 weeks or longer fixing this the first time. They promised when I purchased the truck if there where any issues I would get a loaner vehicle, nothing available to loan on the first time. Now that it’s happened again I called to scheduled a time to repair and they say I can’t even get seen until January 20th. So this truck has costed me a lot of out of pocket money for rentals.

The bolt that holds the left side rear wheel to the axle sheered off. This was discovered when the vehicle had 9,200 miles on it. When the wheel was removed the sheered bolt and washer fell out. Based on the condition of the bolt it was apparent that the bolt had been sheered off for quite some time. This truck has not been off road nor has it been used to pull a trailer yet. The truck is a 2021 Ford F150 Powerboost truck Platinum edition.

Passenger side, rear wheel axle blot sheered off, been loose for ??? Was told not to drive the vehicle, safety issue. Seems to be a common problem with the Mac towing package.

Heard squealing in brakes and rattling in passenger rear area. Took to Ford service and they found loose bolt head and washer that was sheared. Recommended not to drive vehicle but could not confirm that it is a warranty issue at this time. Less than 24k miles on vehicle.

ON 10/22/2022 I TOOK MY TRUCK IN TO THE FORD DEALERSHIP FOR OIL CHANGE AND TIRE ROTATION, UPON ROTATING THE TIRES THE TECHNICIAN FOUND THE AXLE BOLT ON THE REAR DRIVERS SIDE WAS SHEARED OFF AND PART OF THE BOLT WAS STILL IN THE AXLE. THE DEALERSHIP KEPT MY TRUCK AND ORDERED A NEW BOLT AND GAVE ME A VEHICLE TO DRIVE. MY TRUCK HAS 26,744 MILES ON IT. I AM CONCERNED AFTER READING MANY POSTS ON FORD FORUM THIS WILL CONTINUE TO HAPPEN AFTER WARRANTY EXPIRES. SOME OF THE POSTS STATED FORD DEALERSHIPS WERE REPLACING THE AXLES. PLEASE ADVISE THANK YOU

Vehicle lurches forward when transmission is in drive position, when stopped with foot on the brake. It is very forceful and feels like being hit from behind. It could easily cause a collision with a car stopped in front of my vehicle.

I took my 2021 F150 Powerboost with Max Tow package into the Ford dealership for service and to inspect a noise coming from the driverside rear wheel. When the wheel was removed the source of the noise was confirmed as a sheered-off axle retaining bolt. I was told by the service department the truck was unsafe to drive. I am unsure if this nut holds on the wheel hub assembly but I'm guessing it could lead to loss of power in the affected drivewheel or loss of the wheel altogether. Upon doing some internet research this is quite a common issue with the 3/4" floating axle that was new to the 2021 model year for the Max Tow package. This is an issue with the drivetrain of the vehicle that could lead to safety issues for the occupants and others and should be recalled with upgraded/redesigned parts.

When I come to a stop, my truck will try to lunge/jump forward after a few seconds. It has been happening for a few weeks now. This could result hitting another car in front of me or potentially a pedestrian if I am stopped at a cross walk. I took it a dealer yesterday and they confirmed the problem. They attempted to reprogram it and said it fixed it. Later that night and again this morning, it did it again.

The rear axle bolts sheared off for unknown reasons. The symptom was a metallic rattling noise from the back of the vehicle - the noise was pieces of the axle bolts bouncing around inside the wheel center cap. The bolt in questions holds the rear axles in place. Vehicle has been at dealership for 2 weeks as they said it was a common problem that is a safety issue. Said it was possible for one or both of the rear wheels to fall off if I had continued driving it. Obviously losing one or two wheels is a huge safety concern. My dealer said he has seen this exact issue 4-5 times on similar trucks. Vehicle is less than 9 months old and has less than 13,000 miles on it. Vehicle is being repaired under warranty but using the same parts.

A noise being heard any the rear-end of the truck. Upon taking the rear tire off for investigation a bolt head was noticed in the center of the rim. This bolt came from the axle. The bolt in question holds the axle in place, if driven for a great distance then a chance of the axle floating towards the gear which could have caused a major safety concern for the occupants of the truck and anyone on the road Truck is currently at the shop, but dealer is replacing parts with same components. No root cause has been found to address concern. Other side of axle could reflect the same condition

There is a fairly common issue where there are bolts at the end of the rear axles (P/N 19S426) have the bolt head shearing off and rattling around inside the wheel. I had one such broken bolt. The issue is large enough that hundreds of owners are reporting this on Ford Truck forums, namely on the 2021 Ford F-150 Powerboost with the Max Tow Package like mine. Ford needs to recall this.

I brought my truck in for routine maintenance oil change & tire rotation and was notified by the dealership that the right rear axle bolt was broken off and that the axle needed to be replaced and that it wasn’t safe to drive it until it was replaced well here’s my problem I didn’t know it was broken or unsafe to drive and had I not brought it in for the oil change early I would still be driving it like that this is a serious problem which could result in a loss of control and accident I’m not the only one that has had this happen I’ve researched it a little and found multiple people on an F150 forum that have had the same experience

Passenger rear axle bolt broken. This seems to be happening only on Max tow equipped vehicles, LOTS of them.

When in regular use of this hybrid Powerboost F150, the truck lurches forward on electric motor power as if you just got rear-ended. This happens every single time you have to come to a stop for more than 5 seconds. The only way to avoid this issue is to drive in"tow/haul" mode which keeps the truck's engine running. This defeats the purpose of a hybrid truck, and you have to remember to switch the running mode from normal to the haul/tow mode. This lurching had to be causing extra wear and tear on the drive train parts. Apparently the problem is a faulty "Transmission Fluid Auxiliary Pump". Many of us on the Ford F150 forums are waiting on our dealers for this back ordered pump. Apparently Ford continues to build vehicles while falling to provide a replacement pump? I am concerned as to the design of this pump as well. My"new" truck only has 7800 miles on it, a little over one year old, and the pump is defective. Is this going to be a reocurring problem? This is a safety issue and should be addressed ASAP. Thank you for your attention to this matter..

Rear differential, passenger side axle bolt broke off. I removed the right rear wheel after hearing a metallic noise while braking to inspect, as soon as I removed the wheel a broken head bolt and washer fell out and you can clearly see the other piece of the bolt is still in the axle shaft. I am not sure if this bolt breaking off could cause loss of wheel or axle. But now my brakes are making noise, I believe as a symptom directly related to this issue. I looked up 2021+ F150 forums and customers with this max trailer tow axles are experiencing the same thing. I took the vehicle to the dealer today to get this inspected and am awaiting an update. The only indicators of a problem was loud metallic noise while braking, and a slight ringing sound while driving without braking. It was all sounding in the rear of the vehicle.

My 2021 Ford powerboost Lariat lurches forward when at a stop in normal drive mode, it feels like someone rear ended the truck.This is a safety hazard if I don’t have my foot pressed hard on the brakes I could be launched into on coming traffic or hit someone crossing the street.

Heard a metal grinding coming from the rear axle on . Took it to Ford dealer maic Haik in Georgetown Texas. The found the axle bolt had sheared off. It is in the shop currently waiting a warranty repair and the shop indicated this was not the first one they had seen.

Myself and several other individuals with 2021/2022 Powerboost F-150s are experiencing an issue where the whole vehicle will lurch forward as if hit from behind after coming to a stop. This can result in the truck hitting the vehicle in front of you if you are in tight traffic.

13800 miles, broken axle/wheel bearing retaining bolt. Screeching noise. Bad wheel bearing. Dealer will not replace wheel bearing because they do not correlate the broken bolt to a bad wheel bearing. Leaving me with a bad wheel bearing that I consider prematurely worn out and is making a clicking sound. Dealer says they cannot replicate the noise so will not investigate further

In May 2022, the passenger side right rear axle bolt sheared off creating a squealing/grinding noise from that wheel. The only thing holding the wheel onto the axle were the brake caliper bolts. The repair involved a new axle. In early Sept 2022, the driver side rear axle bolt sheared off with the same results. The vehicle is now in the shop waiting for the parts to arrive. Dealer advised that this is a serious safety issue and requested that the vehicle be towed to the service center.

The driver side rear axle retaining bolt sheared off rendering the truck not drivable. The truck is at the Ford dealership I purchased it from waiting for a replacement part. This is such a common problem that the axle shaft is on back order, so I am without my truck until the parts are available. Upon researching online I have found this to be a common problem that Ford is very much aware of but have not taken action to correct.

Rear axle bolt sheared off. Per Ford axle must be replaced

The contact owns a 2021 Ford F-150. The contact stated that while driving at various speeds, a humming and tapping sound was present coming from the rear undercarriage of the vehicle. The vehicle was taken to the local dealer who diagnosed that the underbody insulator was faulty and had caused damage to the driveshaft. The vehicle was not yet repaired. The manufacturer was notified of the failure. The contact indicated that the vehicle was previously inspected under the NHTSA Campaign Number 21V986000 (Power Train, Structure) however, the vehicle experienced a failure after the inspection. The failure mileage was 26,836.

Mileage: 26,836

Drivers side rear axle bolt sheared off. Noticed noise coming from rear while driving, removed wheel, bolt head and washer fell to the ground. Bolt head and washer we’re both retained. Local dealerships (albuquerque, NM) do not have the capacity to diagnose the truck for a minimum of two weeks. The structural integrity of the axle and drivetrain are in question.

Broken retaining bolt holding the wheel on the right rear axle. Dealer said too dangerous to drive so they replaced axle. Dealer has old axle and broken bolt. This problem exists in the 2021 F150 Powerboost truck with 9.75 in 3/4 floating axle. Several postings on F150 forum of this happening to others with same truck. Nothing holding rear wheel on except brake caliper if bolt brakes and wheel wobbles loose. When service tech takes wheel off to rotate tires the broken bolt falls on the floor.

Rear passenger axle bolt sheared off.

When drive train goes into electric drive mode, the vehicle will jump/lurch/bang after stopping like I was hit by another car pretty hard. This will only happen when the engine either goes into hybrid electric mode or engine turns off after a stop in sport and other modes. It will not happen in tow mode where the engine stays on. The issue is the aux pump on the transmission going bad, this was found by dealer and part is on national backorder. Truck can jump a foot forward at red light if foot is not smashing the brake pedal down - seems to be an issue popping up daily on forums from others having issues.

The contact owns a 2021 Ford F-150. The contact stated that the gear shifter seized while shifted in park(P) and was unable to shift to the intended gear. Additionally, the gear shifter fractured when the contact forcefully shifted out of the park(P). The contact had been waiting for the vehicle to be towed to the dealer; however, the vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure and was forwarded to roadside assistance. The failure mileage was approximately 1,500.

Mileage: 1,500

Truck does not always does not always downshift to a lower gear at a stop and instead remains in 8th gear. This poses a safety risk do to a lack of acceleration and also causes an unanticipated sudden jerk when it does finally does engage in a lower gear.

I took the vehicle in for a tire rotation and oil change at approximately 18,000 miles. The dealer informed me that the passenger side rear axle bolt had sheared off and that the bolt had to be drilled out and replaced. The repair did not solve the problem and now the axle has to be replaced.

Outer axle bolt sheared from passenger front axle assembly. Both passenger and driver axles had to be replaced because of grinding noise and nut/bolt found in center cap of wheel.

Axel bolt sheared off for rear drivers Axel. Only part holding tire on was break rotor and caliper. The dealer found during a routine oil change/tire rotation. The only symptoms was shifting hard when driving, and slight rattle when driving as the bolt head was caught in the wheel center.

The Check Engine Light illuminated and brought to Ford dealer. Was advised it has code P237C which is a failed Exhaust Heat Exchanger, dealer ordered part # ML3Z5A212W. There is no coolant leak visible from the failed part. But driving down the highway around 70mph, the vehicle suddenly decelerates and goes into Reduced Power Mode, throttling back the engine. The reduced power mode is displayed on the instrument cluster, but it is still startling to have the vehicle decelerate, especially at highway speeds in traffic. And would be more problematic with a trailer in tow. My Ford dealer has the part on order but Ford states it is on back order with no expected delivery date. Very disappointing from a quality stand point, but a concern as well from a safety perspective. I know others have had a similar issue which is also accompanied by a coolant leak, which I do not have on my vehicle but I am concerned and continue to monitor for leaks and watch the fluid level. I do not have any photos of the valve. Unexpected reduction of engine power in my opinion is a safety issue, especially at highway speeds or when towing. Thank you for your review of this issue.

They have had this recall since Dec 16th and I have taken the truck and called the dealer several times and they said that Ford has not remedied this recall yet. It is a huge issue and they aren't doing anything about it, several online forms have cited this exact problem with their truck yet Ford is not fixing it.

Fails to accelerate when switching from electric power to gas power. This happens when pulling out of a parking lot onto a Houston,Tx feeder street after the truck has set for awhile and on electric power when started and medium to full power is used to merge into traffic. The switch over from appears to work but shows no turbo boost causing a lack of power to merge safely and this only happens after first start the rest of the day truck operates normally or until it is shut off again for awhile making this truck a accident waiting to happen. Yes the service manager witnessed this so left truck to be repaired but since no engine check lights or codes he had to call ford without knowing all the answers from one little short ride they came back with a answer that was unacceptable blaming it on a clutch operation that was normal. If so why does it happen only after new start and corrects itself?
