The affected vehicles are equipped with a single exhaust system. The rear axle wiring harness bundle may make contact with the rear axle housing, which could damage the wiring harness, causing the electric parking brake to activate unexpectedly. This could potentially result in loss of control of the vehicle, increasing the risk of a crash.
The recall affects an estimated 870,000 vehicles.
Dealers will install a protective tie strap, tape wrap, and replace the harness as necessary, free of charge. Owner notification letters are expected to be mailed September 11, 2023.
According to Automotive Fleet, Ford's Critical Concern Review Group (CCRG) opened an investigation into reports describing unintended parking brake application on 2021 model year F-150 vehicles in February 2023. The warranty and field reports indicated damage to the wiring containing the rear electric parking brake circuits.
