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.
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!.
Computer screen goes black. Sometimes this happen right when I start the truck, sometimes when put it in reverse and sometimes just while driving down the road. This started shortly after I purchased the truck in Feb 2025 and seems to be getting worse.
Rear backup camera and distance sensors stopped working. The issue is intermittent this issue could have resulted in an accident or injury/fatality due to no image sensor information no dealer involvement at this time no outside inspections at this time no prior warnings or messages were given before the failure.
(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.
Truck does not detect specifically silver Ford cars when auto parking. It will try to park in the same spot as them on sunny days.
