What 937 owners told NHTSA about the 2021 Ford F-150 Supercab Diesel

My 2021 Ford F-150 intermittently displays the warning message “Reverse Brake Assist Not Available – See Manual” when the vehicle is placed in reverse. When this message appears, the reverse brake assist / parking collision warning feature is not available, which may reduce safety while backing up. The vehicle was inspected by a Ford dealership. The dealership confirmed DTC U3000:49 in the IPMA module and identified Ford TSB 23-2040 as applicable to the concern. The dealer stated that the repair requires an IPMA software/module update and calibration. The quoted repair cost was approximately $1,100. This appears to be a software/programming-related condition affecting a driver assistance and brake-related safety feature, not normal wear and tear or a failed mechanical component. The warning is intermittent, but it has appeared multiple times. The vehicle is available for inspection upon request. No crash, injury, or fire has occurred. Ford Customer Support was contacted and case number XXX was opened. Ford advised that no active warranty, recall, or customer satisfaction program currently provides repair cost coverage, and that because this involves Reverse Brake Assist, I may choose to file a safety concern report with NHTSA.

When I'm driving my truck, usually when I have come to a stop on an incline, the parking/emergency brake will engage on its own. For example, most recently I was pulling out of a driveway with an incline. I was stopped at the bottom of the driveway to wait for the roadway to clear before I pulled out. When I hit the gas to go, the rear wheels skidded and the truck came to a stop in the oncoming traffic lane. I looked at the dashboard and saw that the parking brake symbol was on, indicating that the parking brake had engaged. I did not engage the parking brake- the truck did it on it's own.

THERE IS A WARNING ON MY DASH WHEN THE VEHICLE IS PLACED IN REVERSE: REVERSE BRAKE ASSIST NOT AVAILABLE SEE MANUAL. THIS CONCERN HAS A TSB ATTACHED TO IT. MY CONCERN IS THAT GIVEN THE SAFETY NATURE OF THIS CONCERN AFFECTING F150S AND FORD MUSTANGS; THIS SHOULD BE COVERED BY THE MANUFACTURER AND NOT THE CONSUMER. FORD WILL REPAIR, HOWEVER, INVOICE THE CUSTOMER FOR THE COST WHICH I DO NOT AGREE WITH. I AM NOT CERTAIN HOW MANY VEHICLES ARE AFFECTED OR IF IT RISES TO THE OCCASION OF A SAFETY RECALL; BUT SHOULD BE INVESTIGATED FURTHER. THANK YOU!

1. Electrical System Failure: While traveling on highway, alternator failed suddenly within 2 minutes of “service soon” and “check electrical system” warnings. Caused complete loss of motive power, electronic parking brake locked up while driving, loss of power steering, all gauges failed, transmission shifted into park while in motion. Battery was damaged (“fried”). Engine continued running for several minutes after stop without ability to shut off ignition. Incident documented by Ohio State Highway Patrol. 2. Seat Belt Issue: Driver-side seat belt interlock sticks in unlocked position, creating risk of failure to lock during a crash. 3. Electronic Parking Brake: Intermittently engages while vehicle is moving downhill to a stop (mostly at or below 5 mph). Parking brake light flashes three times then turns solid while in motion. Ford TSB indicates vehicle not eligible for related recall. 4. Infotainment System: Intermittently freezes, requiring forced reboot. Preceded by audio glitches, laggy dash computerized systems. 5. Transmission: Severe clunk and physical jolt when decelerating from ~30 mph to 8 mph. Also occurs during acceleration, particularly upshifts from 2nd to 3rd and 3rd to 4th gears, more pronounced when turning. 6. 4WD System: Intermittently fails to disengage from 4WD HI to 2WD HI. “Failure to shift” message appears several minutes after command to return to 2WD HI. 7. Front Differential/Axle: Previously, faulty front differential housing fractured due to system malfunction, causing intermittent loss of front driveline engagement in 4WD LO (250-500ms delay then re-engagement under throttle). Ford replaced front differential and axle under warranty after vehicle out of service for 2.5 months. Abbreviations: 4WD HI = 4-Wheel Drive High Range; 2WD HI = 2-Wheel Drive High Range; TSB = Technical Service Bulletin.

Giving an error of reverse assist and not available when starting truck and when placing truck in reverse. Have look up to seen if included in the recall that was issued 6 days ago.

My Ford F-150 is subject to Manufacturer Recall Number23S65/NHTSA Recall Number23V896. I asked for the repair multiple times, but the dealership repeatedly told me that the parts were on backorder. The hub bolt on my right rear tire cracked and the truck was making a high pitched sound. I took it to the dealer and they said the bolt was cracked and driving it in that condition is dangerous. The truck is not safe to drive, but the parts remain on backorder indefinitely.

I was in the parking lot of my local grocery store, and the truck all of a sudden gave me an indicator that there is a "park brake fault-service now." I was stranded and had to have someone pick me up for this, This is after hours so I cannot call the Ford dealership until the following day. I now see Ford issued a recall for this under 23S35. However, when I look up my VIN under Ford, that did not show, and thus, we did not address this earlier when that should have happened. That is a problem and needs to be addressed with Ford ASAP. What if I was driving and this happened??!!

Started after McGee ford did a service on my truck Apparently they told ford they repaired electrical recalls which I wasn’t having issues with nor did I know They did anything! They did however erase the recalls so that was 8-2024 shortly after my truck experienced major electrical issues, another dealership told me it was gonna be 6k and 4 weeks to fix I was in awe I left with my truck that had no blinkers no air bags and so on 15 safety codes! I battled this for a year and then my parking break locked up while driving 70 on the highway! That’s the recall megee claimed they fixed I’m not rich single dad 100% of rhe time and I sure my kids everywhere daily, I do research call ford find intact i had a recalll so im thinking it will get fixed! 6 weeks later they not fixed i was told 2 days Now heritage and ford won’t fix it they want megee ford the certified service and dealer to pay for it. It’s winter im a contractor in Vermont they let me borrow a Sentra with summer tires on it. Couldn’t make it off my road. I’m still driving my kids around! I almost reck once a day as the whole system is messed up now! I feel like I’m being bullied and picked on because of my nationality

My truck thinks my parking brake is engaged so it constantly flashes the “brake” light, constantly chimes while driving and says parking break malfunction, talk to dealer. I brought it to Webber family Ford in Detroit lakes MN 56501 and they checked it over including the safety recall location for recall 23S35. They said it was not the recall location and I would have to bring it in Monday for another appointment. When I got it home that day I crawled under to check that location. I see visible green which usually means corrosion and the protection around the harness seems warm. I also noticed the "recall" was not completed how it is shown on fords recall paperwork using the zip tie as a wear location so it isn't the harness itself. That is not how mine is. I have photos to prove that. I spoke with corporate ford today and they said they can't re open the recall because it has been closed and it is past its 12 month warranty being it was done in October of 2023 before my ownership and at a different dealer. I don't believe it is fair to me the current owner to pay for the cost of a rerepair of a recall that was done incorrectly.

I was traveling 47 mph and suddenly the parking brake was activated, causing the car to brake instantly. Luckily, no one was behind me and luckily it did not cause an accident. There were no lights on the dashboard. I took it to the Ford dealer to have it inspected and they gave me an appointment for 8 days later and let me go home knowing that I could not drive it since I almost caused an accident.

Purchased vehicle w/ roughly 5000miles in 2021 from Ford Dealer. All stock items and factory tires. At roughly 50,000 during state inspection, it was found that the front passenger brake line was chafing on tire and was deemed unsafe by the Ford dealership. No prior work or modifications was done in this area. Research indicates that this is happening to other Ford F150s

While driving the parking break activated. I was in the middle of the road with my newborn. I believe my truck should have been recalled since this is something that other F150 had. I took it to the Ford dealership and they said there was no active recall on this vehicle. So I had them check it since it’s such a high safety concern. And yes there was a default with the parking break system.

I contacted a local Ford dealership: Hempstead Ford, 301 N Franklin St, Hempstead, NY 11550, (516) 363-1579 to perform multiple safety recalls issued by NHTSA. The service department refused to schedule me for service because I did not buy the vehicle from their dealership. I reported this to Ford Customer Relations and was told that they cannot force the dealership to service my vehicle. I believe this is illegal.

Truck was repair as per the recall of the emergency brake however is still applying the parking brake again and took it to have it scan but ford dealer ship says they don't find no codes or anything saying it does and I'm just scared of continuing to put myself and my family at risk when is still applying the emergency brake whenever it wants. So far has done it over 3 times in a period of a few moths after the recall was supposedly been done for that same reason. On the picture I'm posting here is the invoice of the repair of the recall. Is in Spanish part of it but all the numbers of the recall are there

While approaching a red traffic signal at speed, I went to apply brakes and the brake pedal had no resistance and failed to slow the vehicle. Immediately several alarms sounded and lights illuminated on the dash board. I was able to slow the vehicle with repeated brake attempts and swiftly moving to the right turn lane where I could navigate a turn and come to a complete stop after coasting. Dashboard indicated: Pre-collision assist not available, antilock brake fault, service AdvanceTrac, and check brake system.
