The official notice
Defect
On certain vehicles, the shift cable may detach from the transmission. This could cause the transmission not to shift gears when the shifter is moved. As a result, the transmission could be in a different gear than the gear shifter indicates. If a driver attempts to exit the vehicle while the transmission is not in Park, and the parking brake is not applied, the vehicle could move suddenly.
Safety Risk
Sudden and unexpected movement of the vehicle could increase the risk of a crash.
Remedy
Ford will notify owners by mail and instruct you to take your vehicle to a dealership to replace the transmission shifter cable bushing and install a protective service cap. Ford advises that you should apply the parking brake each time the vehicle is parked.
