Mazda B-Series Truck Recall 21V162: Driver Air Bag Inflator May Explode, Sending Metal Fragments

NHTSA campaign 21V162, reported March 10, 2021, 5,847 vehicles potentially affected.

What this recall means for you

The driver-side front air bag inflator in these trucks can rupture because its propellant degrades over time after long exposure to high humidity and heat. An inflator explosion can throw sharp metal fragments toward the driver or other occupants, which may cause serious injury or death.

Mazda will replace the driver-side air bag inflator with an alternate part at no cost to owners, and authorized dealers will perform the repair. Owners who received an interim letter in April 2021 or a follow-up letter in December 2021 should still schedule the repair. You can also check your vehicle's VIN for open recalls and contact Mazda customer service at 1-800-222-5500, option 4, referencing recall number 4821C.
