The official notice
Defect
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE WINDSHIELD WIPERS MAY STOP WORKING DUE TO A SEPARATION BETWEEN THE DRIVE PIN AND CRESCENT IN THE CRANK ARM ASSEMBLY.
Safety Risk
DRIVER VISIBILITY COULD BE REDUCED, INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL INSPECT THESE VEHICLES FOR THE PRESENCE OF A PLASTIC WATER DEFLECTOR AND, IF NECESSARY, REPLACE THE WIPER MOTOR CRANK ARM AND INSTALL A WATER DEFLECTOR. ON VEHICLES RECEIVING A REPLACEMENT CRANK ARM AND NEW WATER DEFLECTOR, DEALERS WILL ALSO APPLY ADDITIONAL SEALING MATERIAL TO IMPROVE WATER DEFLECTION AWAY FROM THE CRANK ARM ASSEMBLY AND WILL INSTALL A REINFORCEMENT TO IMPROVE THE PERFORMANCE OF THE WIPER PARK MECHANISM.
