The 2009 BMW 328i has 5 recalls, the most serious being a driver's airbag inflator that can explode during deployment, sending sharp metal fragments into the cabin and potentially causing serious injury or death.
Two separate fire risks also affect this vehicle. The heater for the crankcase ventilation valve can short circuit, melting internal components and raising the risk of an engine fire even when the car is parked. Separately, the wiring and connectors that control airflow through the heating and air conditioning system can overheat and melt, also creating a fire risk while the vehicle is unattended. Rounding out the list, the positive battery cable connection at the fuse box can degrade over time, causing intermittent loss of electrical power and potentially stalling the engine while driving.
