The company says in documents posted by government safety regulators Friday that a rear wiring bundle can come in contact with the rear axle housing. That can chafe the wiring and cause a short circuit, which can turn on the parking brake without action from the driver, increasing the risk of a crash.
So not to downplay Fords mess up or the big recall but its interesting to me how easy a fix this is as long as you know exactly what bundle of wires you’re looking for down there. Take it in for the free maintenance though, please do not DIY an auto recall.
