The 2011 BMW M3 has 4 recalls, the most serious being a driver's frontal airbag inflator that can rupture and send metal fragments into the cabin, posing a risk of serious injury or death to the driver or passengers.
The airbag inflator issue has been the subject of multiple recall filings, and prior repair attempts did not fully resolve the problem for all affected vehicles. On the electrical side, the positive battery cable connection at the fuse box can degrade over time, causing intermittent loss of power that may stall the engine without warning while driving. There is also a separate wiring concern involving the heating and air conditioning system: the wiring and connectors that control airflow through the climate system can overheat, melt the surrounding connectors, and potentially start a fire even when the car is parked and unattended.
