Recalls for 2007 GMC Sierra 3500
3 NHTSA recall campaigns affecting ~340,268 vehicles.
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.
General Motors LLC (GM) is recalling certain model year 2007-2008 Chevrolet Silverado 2500HD and 3500HD trucks manufactured November 28, 2006, to August 29, 2008, and 2007-2008 GMC Sierra 2500HD and 3500HD trucks manufactured November 27, 2006, to August 29, 2008. The affected vehicles are equipped with a passenger side frontal air bag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture upon its deployment.
General Motors LLC (GM) is recalling certain model year 2007-2011 Chevrolet Silverado HD 2500/3500 trucks manufactured January 18, 2007, to June 22, 2011, and GMC Sierra HD 2500/3500 trucks manufactured January 22, 2007, to June 21, 2011, and equipped with an auxiliary battery.
