NHTSA's recall notice

As NHTSA's recall record states it for campaign 21V051000.

Defect description

General Motors, LLC (GM) is recalling certain 2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado 1500, Silverado 2500/3500, Suburban, Tahoe, GMC Sierra 1500, Sierra 2500/3500, Yukon, and Yukon XL originally sold, or ever registered, in the states of 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 or "Zone A." These vehicles are equipped with non-desiccated passenger frontal inflators containing phase-stabilized ammonium nitrate (PSAN) propellant. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.

Safety consequence

An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.

Manufacturer remedy

GM will notify owners, and dealers will replace the front passenger air bag inflator with an alternate one, free of charge. Interim letters notifying owners of the safety risk were mailed on February 22, 2021. Second notification letters will be mailed once the remedy is available. Owner notification letters were mailed on May 11, 2021. Owners may contact Cadillac customer service at 1-800-458-8006; Chevrolet customer service at 1-800-222-1020; and GMC customer service at 1-800-462-8782. GM's number for this recall is N212328770.
