OVERHEATING COULD LEAD TO A FIRE, EVEN WHILE THE VEHICLE IS NOT IN USE. AS A PRECAUTION, OWNERS ARE ADVISED TO PARK OUTSIDE UNTIL THE REMEDY HAS BEEN MADE.
The insulated connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.
BMW will notify owners of affected vehicles beginning in April of 2012. If you are experiencing problems with the trunk mounted battery cable connections, or you don't receive notification and you feel you should have, please contact your dealer. It’s helpful to have your vehicle identification number (VIN) handy when you call.
