Ferrari North America (Ferrari) is recalling certain model year 2009-2011 Ferrari California vehicles manufactured February 16, 2009, to July 8, 2011, and model year 2010-2011 458 Italia vehicles manufactured March 5, 2010, to July 29, 2011. These vehicles are equipped with 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 air bag deployment, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
