Visibility:power Window Devices And Controls 2015-09-24 · campaign 15V599000 · 9,932 vehicles
Defect: General Motors LLC (GM) is recalling certain model year 2006-2007 Buick Rainier, Chevrolet Trailblazer and GMC Envoy vehicles, and 2006 GMC Envoy XL and Chevrolet Trailblazer EXT vehicles. Fluid may enter into the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board, causing window switches to become inoperative.

Risk: The protective coating may not eliminate the risk that the circuit board could short and result in a fire, even while the vehicle is unattended.
Fix: GM will notify owners, and dealers will install a new driver's door switch module, free of charge. The recall began on November 2, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is 15700.
Exterior Lighting:headlights 2015-08-14 · campaign 15V519000 · 429,170 vehicles
Defect: General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
