It seems the windshield wiper module motor assembly may become damaged from rainwater leaking inside. This could lead to a partial or complete breakdown of the windshield wipers, reducing visibility during crucial moments, like rainstorms.
The fix simply involves the dealer replacing the wiper module assemblies with vented wiper-motor housings, which will be done free of charge. Owners can contact Chrysler at 800-853-1403 or the NHTSA Vehicle Safety Hotline at 888-327-4236.
