BMW 5 Series, 6 Series: Electrical
Affects BMW 5 Series, 6 Series · 2004–2010 — about 17K vehicles.
The hazard
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.
