The 2009 BMW 335xi 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 for serious injury or death.
Both airbag concerns involve the driver's side inflator. One affects vehicles with their original steering wheel, and the other involves vehicles where the original steering wheel was replaced with a sport or M-sport wheel carrying the same type of faulty inflator. Either way, the risk is the same: a violent inflator rupture during a crash that turns the airbag itself into a source of injury. The third recall involves the wiring and electrical connectors that control airflow for the heating and air conditioning system. This wiring can overheat and cause the connectors to melt, which raises the risk of a fire that can start even when the car is parked and unattended.
