  • 20V011000 Jan 2020 Air Bags

    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.

    Fix. 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.

The whole-line score for 2007, mostly half-tons: 2007 GMC Sierra.

No Lemon Index score: automakers report heavy-duty pickup sales together with the half-ton (one F-Series, Ram or Silverado number), so there is no honest per-truck denominator. These are counts and shares of owner complaints, not failure rates. Complaints: NHTSA owner complaints filed under the truck's 2500/3500 (F-250/F-350) names, all years filed, one per complaint number. Engine: decoded from the complaint's VIN (position 8 is the engine code) with NHTSA's vPIC decoder. Complaints filed as just “Silverado” or “Sierra” are left out (they mix 1500s and HDs). Older trucks have had more years to collect complaints, and popular years draw more because more were sold.
