The 2008 BMW 330xi has 3 recalls, the most serious being two separate airbag inflator defects where the driver's frontal airbag can explode during deployment and send sharp metal fragments into the cabin, with the potential to cause serious injury or death.
Both airbag concerns involve the driver's side frontal inflator. One affects vehicles that may have had their original steering wheel swapped for a sport or M-sport wheel carrying a defective inflator module, while the other is a broader inflator defect across the 3 Series lineup. Either way, the real-world risk is the same: a deploying airbag that ruptures violently rather than inflating properly. On the electrical side, the wiring and connectors that control airflow for the heating and air conditioning system can overheat and melt, raising the risk of a fire that can start even when the car is parked and unattended.
