317V047000 · Air Bags:frontal:driver Side:inflator Module
Jan 20, 2017
BMW of North America, LLC (BMW) is recalling certain 2000-2002 BMW 320i, 323i, 325i, 325xi, 330i, 330xi, 323Ci, 325Ci, 330Ci, M3, 323iT, 325iT and 325xiT vehicles, 2001-2002 525i, 530i, 540i, M5, 525iT and 540iT vehicles, and 2001-2003 X5 3.0i, X5 4.4i, and X5 4.6is vehicles. These vehicles may have had a driver-side air bag module installed as replacement equipment such as after a vehicle crash necessitating replacement of the original air bag, or as a remedy part for a prior recall. These replacement modules contain an air bag inflator that may rupture due to propellant degradation occurring after long-term exposure to lower absolute humidity, temperature and temperature cycling.
Consequence & remedy
Consequence: In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Owners are advised not to drive their vehicles until the vehicle has been remedied. BMW will notify owners, and dealers will inspect the driver side air bag module, replacing it as necessary, free of charge. The recall began March 15, 2017. Owners may contact BMW customer service at 1-800-525-7417.

Please note that the 5-series and X5 vehicles are only included if they are equipped with the optional sports steering wheel. The affected vehicles are equipped with a dual-stage driver frontal air bag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture.
Consequence & remedy
Consequence: In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Owners are advised not to drive their vehicles until the vehicle has been remedied. BMW will notify owners, and dealers will replace the front driver air bag module, free of charge. The recall began Aug 2016. Owners may contact BMW customer service at 1-800-525-7417. Note: This recall supersedes recall 14V-348 in its entirety. Additionally, vehicles that have had their driver side frontal air bag replaced previously as part of a recall remedy need to have their air bag replaced under this recall as well. Note: On December 17, 2015 BMW removed the model year 2004 X5 3.0i and 4.4i Sports Activity vehicle from this recall. Those vehicles were mistakenly identified as including the air bags that are subject to this recall.
