Ford has announced a recall for approximately 900,000 2021-2023 F-150 pickup trucks due to a problem with the electric parking brake. Specifically, models equipped with the single exhaust system may experience unintended activation of the parking brake. This issue is caused by the rear wiring harness coming into contact with the rear axle housing, resulting in chafing and potential short-circuiting.

The investigation into reports of unintended parking brake applications began in February. During the investigation, Ford discovered that the rear axle housing and wiring harness could come into contact, leading to chafing in certain situations. Additionally, corrosion of the rear axle housing could worsen the damage. Over time, the protective tape and circuit insulation can wear away, exposing the wiring and increasing the risk of a short circuit.
