The ammonium nitrate propellant used in the airbag inflator may experience a material alteration over time due to degradation occurring after prolonged exposure to high absolute humidity, high temperatures, and high-temperature cycling.
In the event of an airbag being deployed, it may underinflate or deploy too slowly, or the excessive internal pressure may cause the inflator body to rupture and metal fragments may pass through the cushion material causing injury to the occupants.
The Mazda B-Series models affected by this recall were manufactured between 1 February and 7 October 1999.
Vehicles equipped with Takata NADI airbag inflator. Model series UN; VIN range: JMZ UN**** 0W 104841 – 121674
