The vehicles were equipped with Non-Azide Driver Airbag Inflators (NADI) and do not contain phase stabilized ammonium nitrate (PSAN) propellant.
Due to a manufacturing issue, the NADI inflators may absorb moisture, causing the inflators to rupture or the airbag cushion to underinflate.
An inflator rupture may result in metal fragments striking the driver or other occupants. An underinflated air bag may not properly protect the occupant, and increases the risk of serious injury or death.
