The 2007 BMW 325i 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, risking serious injury or death.
Both airbag concerns involve the driver's side inflator, though they arise in different circumstances. One affects the original steering wheel's inflator module, which can rupture on deployment. The other involves vehicles where the original steering wheel was replaced with a sport or M-sport wheel equipped with an inflator that carries the same explosion risk. Either way, a crash that triggers the airbag could turn the inflator itself into the hazard. There is also an electrical concern: the wiring and connectors that control airflow for the heating and air conditioning system can overheat, melt the surrounding connectors, and start a fire, including when the car is parked and unattended.
