Federal Safety regulators say water can get inside and cause the wiper to stop working, increasing the risk of a crash. This may be caused by a missing seal in the wiper motor wiring.
Ford says there haven't been any crashes or injuries from the problem.
The cars involved in the recall were built from Aug. 1, 2010 through Oct. 18, 2011. The company expects to begin the free repairs in late May.
