2003 BMW 330Ci Recalls

Driver's Front Air Bag Defective

In a crash that deploys the driver's front air bag, the inflator of the air bag can rupture, causing metal debris to strike vehicle occupants. Dealers will replace the front driver's air bag module free of charge to correct the concern.

Front Airbag Inflator Module

This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. BMW dealers will replace the affected airbag inflator modules to correct this concern.

Injury Possible Due To Airbag Deployment

Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator modules found.
