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.


The brake system vacuum pump check valve can leak oil and contaminate the power brake booster. This can result in loss of power brake assist. Dealers will repair the vehicle as necessary free of charge to resolve concerns.

Certain passenger vehicles may have been built with incorrectly manufactured transmission guide plate part. This may cause the parking  lock system to not activate when the transmission is placed in park. If the vehicle is parked on an incline and the parking brake is not engaged the vehicle may roll away causing an accident. The dealer will repair and replace the automatic transmission guide plate free of charge. The campaign # is 05V504000

my 2005 645ci back glass want come down.and i cannot open the top when the window stuck. what should i do..thanks..harout

LOVE everything about this car EXCEPT problems with wheels. In the 4 years we have owned it, we have replaced 9 wheels due to dents and cracking. We don't even know how this most recent wheel dented and cracked -- the dent is very small, but it is also cracked and now the tire won't hold air. These wheels are AWFUL!!!

The wheels are awful. There was a class action law suit regarding the replacement of the 121 style wheels but BMW is hiding behind the warranty and other B.S. I'm constantly repairing, welding, changing, and buying wheels and tires. Its a shame.
