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 the federal safety agency.

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.

My Ford F-150 is subject to Manufacturer Recall Number23S65/the federal safety agency 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??!!
