- Model year 2007-2008 Cadillac Escalades, Escalade ESVs, Escalade EXTs, Chevrolet Avalanches, Silverado 1500s, Suburbans, Tahoes, GMC Sierra 1500s, Yukons and Yukon XLs originally sold, or ever registered, in Alaska, Colorado, Connecticut, Idaho, Iowa, Maine, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wisconsin, and Wyoming or "Zone C."
The vehicles have non-desiccated passenger front 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.
An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.
What to do
GM will notify owners, and dealers will replace the front passenger airbag inflator with an alternate on free of charge.
Interim letters notifying owners of the safety risk are expected to be mailed beginning March 1, 2021. Second notification letters will be mailed once the remedy is available.
Owners may contact Chevrolet customer service at (800) 222-1020, Cadillac customer service at (800) 458-8006, and GMC customer service at (800) 462-8782. GM's number for this recall is N212328780.
