- Summary
- Some 2021 F-150 vehicles may exhibit a Reverse Brake Assist Unavailable message after module programming has been completed. This may be due to a network interruption from programming or configuring modules, which can cause steering center find to be reset. When the steering center find is reset, this causes various features to become disabled. The steering center find can be relearned by driving the vehicle approximately 5 minutes above 18 mph (30 km/h) straight ahead on a flat surface with no steering inputs for a few seconds. When steering center is found the Reverse Brake Assist Unavailable message will go away.
Owners of these vehicles have filed 77 complaints in the brakes category.
