What's wrong?
The rear axle wire harness on 2021-2023 Ford F-150 trucks carries electrical circuits near the rear axle, including the circuits that control the rear electric parking brake. That parking brake is supposed to apply only when commanded, holding the truck in place after the driver sets it.
On affected F-150 trucks with a single exhaust system, the harness bundle sits close enough to contact the rear axle housing. Over time, that contact rubs through the protective tape and wire insulation. Once copper wiring is exposed, the circuit can ground against the axle housing. If the low-side parking brake motor circuit shorts to ground, the electric parking brake can activate unexpectedly.
A warning sign is a parking brake warning light with a message on the instrument panel cluster. If that appears, the truck is telling you the parking brake system has detected a fault, and the rear axle harness is one part the Ford dealer will inspect under recall 23V509.
Who's affected?
Covers F-150 pickups from 3 model years, all tied to the rear axle wire harness for the electric parking brake.
