2004 BMW 6 Series recalls
Electrical system: 12v/24v/48v battery, cables
NHTSA campaign 12V126000 · reported March 26, 2012 · BMW OF NORTH AMERICA, LLC · 367,682 vehicles potentially affected
- 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.

NHTSA campaign 10V446000 · reported October 1, 2010 · BMW OF NORTH AMERICA, LLC · 198,352 vehicles potentially affected
- The problem
- Bmw is recalling certain model year 2004-2010 5-series, 6-series, and model year 2002-2008 7-series vehicles. A check valve of the brake vacuum pump may leak a small amount of lubricating oil. Over time this could result in contamination of the brake booster.
- The risk

- The fix
- Bmw will notify owners and dealers will repair the vehicles free of charge. The safety recall began on november 24, 2010. Owners may contact bmw at 1-800-525-7417.
