RepairPal Expert Overview:
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 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.
my headlight has mousture in it is there anyway to repaire it without spending 2000 to replace it with a new one plse someone who has had this problem get bak to me thnx
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!!!
