The 2008 BMW 330i has 3 recalls, the most serious being a driver's side airbag inflator that can explode during deployment, sending sharp metal fragments into the cabin and potentially causing serious injury or death.
A separate but related concern involves vehicles where the original steering wheel may have been replaced with a sport or M-sport wheel carrying the same type of defective inflator, posing the same fragmentation risk. The wiring and electrical connectors that control airflow for the heating and air conditioning system can also overheat, potentially melting the connectors and starting a fire even while the car is parked and unattended.
