Despite pressing the button multiple times, the cruise control would not disengage. Same thing while tapping the brakes it would not disengage. The vehicle continued to maintain speed, and the cruise control system remained unresponsive to my commands. In response, I applied the brakes to safely reduce speed, I did not perform a panic stop or abrupt braking maneuver. Once I had the vehicle slowed, I moved safely onto the shoulder of the highway, well away from traffic. I then shifted the vehicle into park, shut off the engine, and restarted the truck. After restarting the vehicle, I elected not to use the cruise control system for the remainder of my trip, which lasted approximately eight additional hours to Houston, Texas, I have not used the cruise control since the incident because I am concerned that the condition could recur and create a safety hazard.

This creates a serious risk of losing vehicle control, particularly at higher speeds, during lane changes, or in emergency maneuver situations. Because the failure occurs randomly and without any prior indication, there is no opportunity to safely prepare or pull over before it happens, putting both the driver and other motorists at risk.

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.
