2021 Ford F-150 Integrated Trailer Brake Control recall 26V104000
Safety recall
Symptoms / what can happen
Trailer lights or brakes that do not function can reduce the driver’s ability to control the trailer and decrease the trailers visibility to other road users, increasing the risk of a crash.
Cause

When towing a trailer, the integrated trailer module (ITRM) may lose communication with the vehicle, possibly causing a loss of brake and turn signal lights, or a loss of brake function. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, " Lamps, Reflective Devices, and Associated Equipment."
