General Motors Corporation has recalled over 850,000 vehicles due to the potential electrical failure that could lead to a vehicle fire. The vehicles in question are equipped with a heated windshield wiper fluid system. When used, the system could potentially short circuit and cause other electrical functions to malfunction greatly increasing the risk of a fire. The recall involves the 2007-2008 model year Chevrolet Silverado, Tahoe, Avalanche and Suburban, Cadillac Escalade, Escalade ESV and Escalade EXT, GMC Acadia, Sierra, Yukon, Yukon XL and Saturn Outlook; 2006-2008 Hummer H2, Cadillac DTS and Buick Lucerne; and the 2008 Buick Enclave. If you drive those vehicles and notice a strange odor or see smoke when using your windshield wipers please return the vehicle immediately to a dealer to have the system fixed free of charge. Dealers will install a wire harness with an in-line fuse system to solve the problem.
