The nuts that secure the windshield wiper arms may not have been tightened to the correct specification during vehicle assembly and as a result, if the wipers are restricted by an external load such as a build up of snow, one or both or the wipers may become inoperative. Inoperative wipers could reduce driver visibility and increase the risk of a vehicle crash. Lexus dealers will install new wiper arm nuts to correct this concern.
