The 2004 BMW 330xi has 3 recalls, the most serious being defective Takata airbag inflators on both the driver and passenger sides that can rupture and send metal fragments into the cabin, causing serious injury or death.
Both the driver and passenger frontal airbags are affected: in a crash that triggers deployment, the inflator can explode rather than inflate normally, turning internal components into shrapnel. There is also a lighting concern: electrical resistance in the rear lamp contacts can cause the taillights, brake lights, or turn signals to stop working intermittently, leaving other drivers without warning of braking or turning intentions.
