BMW issued a recall on the 7 SERIES model

On certain vehicles, the air bag control module housing may contain metallic particles which were left in the module due to a manufacturing process error. These particles could contact components within the module, which could cause a short circuit and briefly render the module inoperative, which could affect deployment of air bags and seatbelt pretensioners in a crash (where deployment is warranted) which could increase the risk of injury to vehicle occupants. Correction: Dealers will replace the air bag control module. Note: The short circuit would result in the air bag light illuminating.
