The problem
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.
The risk
An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.
The fix
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. Owners may contact Mazda customer service at 1-800-222-5500 option 4. Mazda's number for this recall is 4821C.
