On certain trucks, the steering column assembly may not have been manufactured properly. As a result, the shifter could detach from the steering column. If this happens, you may not be able to shift the transmission into the park ("P") position, and the truck could move if the parking brake isn't applied.
A parked vehicle that rolls away could create the risk of an injury or a crash.
Ford will notify owners by mail and advise you to take your truck to a dealership to inspect and, if necessary, replace the steering column.
