NHTSA recall 19V781000

What's wrong: These vehicles had their passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.

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

The fix: Owners are advised not to drive their vehicles until the remedy is 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.
