BMW issued a recall on the 3 SERIES model

Certain 323I and 328I vehicles may experience inadvertent or non-crash side impact lateral air bags deployment. In addition, the Battery Safety Terminal (BST) would also activate, disconnecting the starter cable from the battery. In this case, the vehicle electrical systems would continue to operate and the engine would continue to run; however, after the engine is turned off, it could not be restarted. Correction: Dealers will recalibrate the side airbag system in order to reduce the possibility of such non-crash deployments.
