2006 BMW 325i Recalls

Driver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments

The driver's frontal air bag inflator may deploy the air bag with excessive pressure, resulting in the inflator rupturing and causing metal debris to be sprayed onto vehicle occupants. Dealers will replace the driver's frontal air bag free of charge to resolve the concern.

Airbag System Concern

The front passenger seat contains a mat that determines the presence and size of a seat occupant. This input to the airbag controller helps to determine if and how forcefully the passenger airbag should deploy in the event of a crash. The detection mat can develop cracks and fail. If this were to occur, the airbag would not deploy as expected, increasing the risk of personal injury. Dealers will repair the occupant detection mat to eliminate the possibility it may crack. Additionally certain vehicles will receive and extended warranty on the front passenger seat occupant detection mat.

Control Arm Bolt May Not Be Tight

On 25 vehicles, the bolt securing the front control arm and swivel bearing were not tightened to specification and could loosen over time. If the nuts loosen, vehicle handling and control could be compromised, increasing the risk of a crash. Dealers will tighten the front control arm and swivel bearing connection to the correct specifications. The recall began November 21, 2006.
