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.

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.
