BMW 535i Recall 12V126000
The Positive Battery Cable Connection in the Trunk Can Overheat
Electrical & Lights, March 23, 2012
RepairPal Expert Overview
Our Quick Take:
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.
What Should You Do?
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.
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.
