Recalls affecting the 2003 6

air bags:frontal:passenger side:inflator module

Campaign 18V402000

Mazda North America Operations (Mazda) is recalling certain 2003-2008 Mazda6, 2006-2007 Mazdaspeed6 and 2004 MPV vehicles nationwide. Mazda is also recalling 2005-2006 MPV vehicles in Alabama, Arizona, Arkansas, California, Delaware, the District of Columbia, Florida, Georgia, Hawaii, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, West Virginia, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands. On July 9, 2019 this recall was expanded to include certain 2004-2011 RX-8 vehicles that were previously recalled under 16V-354 but have not yet been repaired. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these passenger air bag inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
