Defect
On certain vehicles, the right-rear halfshaft may not have been manufactured properly. As a result, the right-rear halfshaft could fail and cause a loss of power to the rear wheels. Also, if this happens and the vehicle is parked without the parking brake on, the vehicle could roll away.
Safety Risk
A loss of power to the wheels or a vehicle rollaway 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 inspect, and if necessary, replace the right-rear halfshaft. Ford advises that you should use the parking brake each time that you park the vehicle until the recall inspection/repair is completed.
