The 2002 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 the bag normally, turning the housing into a source of metal shrapnel directed at whoever is seated in front of it. Prior repair attempts for these inflators did not fully resolve the issue across all affected vehicles, which is why multiple filings exist for what is the same underlying hazard. There is also an exterior lighting concern: electrical resistance in the rear lamp contacts can cause the tail lights, brake lights, or turn signals to stop working intermittently, leaving other drivers without warning of braking or turning.
