Air Bags:frontal:passenger Side:inflator Module 2019-10-31 · campaign 19V782000 · 69,879 vehicles ⚠ DO NOT DRIVE

Defect: Mazda North American Operations (Mazda) is recalling certain 2007-2012 CX-7, CX-9, and 2009-2012 Maza6 vehicles.

The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.

Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

Fix: Owners are advised not to drive their vehicles until the repair has been performed. Mazda will notify owners, and dealers will replace the front passenger air bag inflator with an alternate one, free of charge. The recall began December 3, 2019.

Defect: Mazda North American Operations (Mazda) is recalling certain model year 2007-2014 CX-9 vehicles manufactured October 24, 2006, to December 28, 2013. The affected vehicles have front suspension ball joints that may corrode from water leaking into the fitting.
