The official notice
Defect
This recall is for vehicles that had an inspection performed under recall 2019-599, 2019-600 or 2019-601, but where the airbag inflator was not replaced. This new recall will provide replacement of the airbag inflator. On certain cars, exposure to moisture over time could cause the driver-front airbag not to inflate properly in a crash. In some cases, this could cause an airbag not to fully inflate, while in others it could cause it to deploy with more force than normal. It could also cause the inflator to rupture. If the airbag inflator ruptures, small pieces of metal could be propelled toward vehicle occupants or cause damage to the airbag and prevent its proper function.
Safety Risk
In a crash requiring an airbag deployment, the driver-front airbag may not inflate properly or the inflator could rupture. This could create a risk of injury.
Remedy
BMW will notify owners by mail and instruct you to take your car to a dealer to replace the driver-front airbag inflator.
