The 2007 BMW 328i has 4 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.
Two separate airbag recalls cover this vehicle. In addition to the original inflator concern, some vehicles may have had the factory steering wheel replaced with a sport or M-sport wheel equipped with an inflator that carries the same explosion risk. Prior repair attempts did not fully resolve this issue across all affected vehicles.
On the fire risk side, two additional recalls involve electrical components that can overheat while the car is parked and unattended. The heater element inside the crankcase ventilation valve can short circuit, causing plastic components in that valve to melt and potentially ignite. Separately, the wiring and connectors that control airflow through the heating and air conditioning system can also overheat, melting the connectors and raising the same fire risk. Both of these conditions can develop even with the engine off and the vehicle sitting still.
