A glitch in the diagnostic software in the central electronic module could cause the windshield wipers to malfunction and either not turn on when activated or turn on when the driver hasn’t touched the switch. Faulty windshield wipers could lead to a loss of visibility in bad weather and increase the risk of an accident.
Dealers will inspect the module and upgrade the software free of charge. Owners can contact the Volvo customer center at 800-458-1552 or the NHTSA Vehicle Safety Hotline at 888-327-4236.
