TOYOTA issued a recall on multiple vehicle models

On certain vehicles, the wiper arm securing nuts could have been insufficiently tightened during assembly. If the movement of the wipers is restricted by an external load, such as heavy snow on the windshield, the wiper arms could slip and one or both wipers could become inoperative. If this occurs, driver visibility could be reduced, which could increase the risk of a crash causing injury and/or property damage. Correction: Dealers will clean the mating surface of the wiper arm and motor shaft and install improved wiper arm nuts.
