In a defect notice filed with the National Highway Traffic Safety Administration (NHTSA), BMW states, "The problem involves the wiring for the front side airbags and front safety belt tensioners. Specifically, incorrect crimp connectors may have been used on the side airbag and belt tensioner wiring. As a result, sufficient contact between the crimp connectors and the corresponding plug may not occur which could lead to an increase in the electrical resistance of that connector. If that happened, it could be possible for the side air bag and/or the safety belt tensioner not to deploy."
Vehicles experiencing the defect should display an airbag warning sign in the instrument cluster, but owners are advised to heed the recall notice even if they don't see the airbag warning.
