General Motors LLC (GM) is recalling certain model year 2007-2011 Cadillac Escalade, Escalade ESV and Escalade EXT, Chevrolet Avalanche, Silverado 1500, Suburban and Tahoe, GMC Sierra 1500, Yukon and Yukon XL vehicles, and 2009-2011 Chevrolet Silverado 2500 and 3500 and GMC Sierra 2500 and 3500 vehicles originally sold, or ever registered, in Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands. Vehicles not originally sold or ever registered in these states are not subject to this safety recall but may be covered under recall 16V-383, depending on the vehicle model year and the vehicle's sale and registration locations. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.

Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet Customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 49151.
