## What is wrong

Mazda North American Operations \(Mazda\) is recalling certain 2007\-2009 B\-Series pickup trucks.  The driver's side air bag inflator may explode due to propellant degradation occurring after long\-term exposure to high absolute humidity, high temperatures, and high temperature cycling.


## What can happen

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


## The remedy

Mazda will notify owners, and dealers will replace the driver\-side air bag inflator with an alternate one, free of charge.  Owners were notified of the safety risk with an interim letter mailed April 26, 2021.  A second letter was sent December 2021.
