2007 BMW M5 Recalls
The bolt securing the insulated battery cable connector at the trunk floor panel can loosen, causing increased electrical resistance and overheating of the cable connection.
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.
