2004 BMW 6 Series

On certain vehicles, the insulated bulkhead connector (used to join the two halves of the positive battery cable) may have been incorrectly installed during vehicle assembly. Over time, the bolt connection could loosen, which would increase electrical resistance. In addition, an incorrectly insulated bulkhead connector could allow humidity to accumulate at this location, causing current leakage. These issues could cause the cable connection to overheat, which could result in a vehicle fire causing property damage and/or personal injury. Correction: Dealers will inspect and, as necessary, secure the insulated bulkhead connector. In addition, protective grease will be added to the area and the plastic battery positive terminal cover will be replaced.

On certain vehicles, the digital engine management control unit was not produced according to specifications. As a result, engine stalling will occur after a short period of operation. The vehicle may not be able to be restarted. Also, a loss of power steering and, after repeated actuation of the brake pedal, a loss of brake power assistance will occur. If stalling were to occur, the driver would be unable to maintain vehicle speed or accelerate. Steering and braking, while possible, would be difficult. Depending on traffic conditions and the driver's reactions, this could lead to a crash. Correction: Dealers will replace the digital engine management control unit.
