Defect
On certain vehicles, the windshield wiper motor may not have been manufactured properly. As a result, the motor could fail and cause the windshield wipers not to work.
Safety Risk
Windshield wipers that don't work could reduce visibility and increase the risk of a crash.
Remedy
Ford will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the windshield wiper motor.
