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 not deploy correctly, 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 Alpina B3 models affected by this recall were manufactured between 3 June 1997 and 30 June 2000.
