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 front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
Mazda will notify owners, and dealers will replace the passenger frontal air bag inflator with an alternate inflator, free of charge. The recall is expected to begin July 24, 2017.
Owners may contact Mazda customer service at 1-800-222-5500.
