DETROIT - General Motors Corp. is recalling 857,735 vehicles equipped with a heated windshield wiper fluid system for a potential short-circuit problem, according to federal safety regulators.
A short-circuit in the system may cause other electrical features to malfunction, create an odor or cause smoke, increasing the risk of a fire, the National Highway Traffic Safety Administration said on its Web site.
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.

GM plans to install a wire harness with an in-line fuse free of charge to fix the problem, NHTSA said.
Separately, GM is also recalling 88,809 2008-model year Buick Enclave, and 2007-2008 model year GMC Acadia and Saturn Outlook SUVs in 28 states and Washington, D.C.
A build-up of snow or ice on the windshield or the wipers may restrict the movement of the wiper arm in the SUVs and could cause the wiper to detach from its motor, according to the NHTSA Web site.
