The defect

General Motors LLC (GM) is recalling certain 2007-2008 Chevrolet Silverado 2500 and 3500 and GMC Sierra 2500 and 3500 vehicles equipped with non-desiccated, passenger frontal air bag inflators containing phase stabilized ammonium nitrate (PSAN) propellant that were used as interim remedy parts for previous Takata recalls. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.

The risk

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

GM will notify owners, and dealers will replace the front passenger air bag inflators, free of charge. The recall began February 11, 2020. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-866-522-9559. GM's number for this recall is N192290990.
