The 2002 BMW 325xi has 4 recalls, the most serious being Takata airbag inflators on both the driver and passenger sides that can rupture during deployment and send metal fragments into the cabin, risking serious injury or death.
The airbag concern covers both frontal inflators: the driver-side and passenger-side units contain propellant that can explode with excessive force, scattering metal shrapnel rather than inflating the bag safely. Prior repair attempts may not have fully resolved the issue, as multiple rounds of remedies have addressed these inflators across the affected model range.
On the brake side, the rear brake rotors can develop cracks where the brake disc meets the parking brake drum. Under normal braking, that crack can grow until the drum separates entirely from the disc. When that happens, the wheel keeps spinning while the disc stops turning, leaving that corner of the car with no braking ability and raising the risk of a crash.
