BMW Recall 12V-126: Electrical system – cables

Affected: 2004–2010 BMW 5 Series, 2004–2010 BMW 6 Series, 2006–2010 BMW M5 and 1 more. Filed with NHTSA on March 26, 2012, covering about 367,682 vehicles.

The problem

BMW is recalling certain model year 2004-2010 5-series, model year 2004-2010 6-series, model year 2006-2010 m5, and model year 2007-2010 m6 vehicles. The insulated bulkhead 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. As it loosens, an increase in electrical resistance at this cable connection is possible and could cause the cable connection to overheat.

The risk

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 fix

BMW will notify owners, and dealers will inspect and secure the battery bolt cable connection as necessary, free of charge. The safety recall began on April 30, 2012. Owners May contact BMW customer relations and services at 1-800-525-7417.
