RepairPal Expert Overview:
The ground terminal of the windshield wiper motor may have been bent during vehicle assembly.

Loss of wiper function in adverse weather could increase the risk of a crash. Dealers will install an additional ground harness on the wiper motor to correct this concern. This recall is expected to begin by July 15, 2011. The Mazda recall number is 6411F.
