Summary

Issue: On certain vehicles, the power connector for the starter-generator may not have been manufactured properly. As a result, the connection between the connector and the positive battery cable may be loose. If this happens, there could be a loss of power to the wheels and/or the connection could overheat. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Wiring that overheats could increase the risk of a fire. Corrective Actions: BMW will notify owners by mail and advise you to take your vehicle to a dealership. For certain vehicles, the dealer will replace the starter-generator and positive battery cable. For other vehicles, the dealer will inspect and, if necessary, replace the starter-generator and positive battery cable.
