These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
