Defect
On certain cars, there may be a problem with the side curtain airbag inflators. This could cause the airbags to inflate with more force than normal in a crash. It could also cause the airbag inflator to separate. If this happens, pieces could be propelled toward the occupants.
Safety Risk
An airbag that does not work properly could create an increased risk of injury in a crash.
Remedy
To reduce the safety risk, BMW recommends that you should not carry any passengers in your car until the recall repairs are completed. BMW will notify owners by mail and instruct you to take your car to a dealer to replace the left and/or right head curtain airbags, as necessary.
