Defect
On certain trucks, the windshield wiper arms may not have been manufactured correctly. As a result, the wiper arm(s) could break or become detached and may not wipe the windshield properly.
Safety Risk
Windshield wipers that do not work properly could affect a driver's visibility. Windshield wiper(s) that detach from the vehicle could create a road hazard for others. Both issues could increase the risk of a crash.
Remedy
Ford will notify owners by mail. The corrective actions for this recall are under development.
