The recalls are for model year 2006 Chevrolet Trailblazer EXT and GMC Envoy XL; and 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, SAAB 9-7x, and Isuzu Ascender vehicles.
In these vehicles, fluid could enter the driver's door module, according to GM, causing corrosion that may result in a short circuit. A short circuit may cause the power-door lock and power-window switches to become inoperative or only work intermittently. Overheating may also result, causing odor, smoke or fire, GM said in its recall notice.
A fire could occur even while the vehicle is not in use, GM said. GM advised owners of the affected vehicles to park outside until the component has been fixed.
GM said owners will be contacted and dealers will test the driver's door module. If the module is functioning properly, a protective coating will be applied. If the module is not functioning properly, it will be replaced. These repairs will be done free of charge.
GM will notify Buick, Chevrolet, and GMC owners, Isuzu and Saab will contact their respective owners.
The recall is expected to begin July 24, 2013.
