The 2000 BMW 328Ci has 4 recalls, all centered on the same critical hazard: Takata-manufactured airbag inflators on both the driver and passenger sides that can rupture or explode during deployment, sending metal fragments into the cabin.
All four recalls trace back to defective frontal airbag inflators. The driver-side inflators involved are Non-Azide units that can rupture when the airbag fires, and in some cases the bag may also underinflate, leaving the driver without adequate cushioning in a crash. The passenger-side inflator contains a propellant that can destabilize over time and explode rather than burn in a controlled way, with the same result: sharp metal fragments driven toward anyone seated in the front. Prior repair attempts on some vehicles may have introduced replacement inflators that carry the same underlying risk, meaning a previous fix does not necessarily resolve the hazard. Because all four recalls involve the same physical danger at the same severity level, this vehicle has no secondary or lesser issues to weigh separately.
