The 2011 BMW 330i has 3 recalls, the most serious being two separate airbag inflator defects where the driver's frontal airbag can explode during deployment and send metal fragments into the cabin.
The first airbag concern is part of a broad Takata-related campaign covering multiple BMW models: the driver-side inflator can rupture violently rather than deploy cleanly, throwing sharp metal fragments toward the driver or other occupants. The second airbag concern involves vehicles where the original steering wheel may have been replaced with a sport or M-sport wheel carrying a similarly defective inflator, presenting the same risk of fragmentation in a crash. Both defects carry a risk of serious injury or death. On the electrical side, the wiring and connectors that control airflow through the heating and air conditioning system can overheat, melt the surrounding connectors, and start a fire, including while the vehicle is parked and unattended.
