Electrical system: 12v/24v/48v battery: cables
- What is wrong
- 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.
- 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.
- Remedy
- 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.

What 2008 BMW 6 Series owners say
Most recent owner complaints, unedited.
Shows the bmw logo then screen goes blank and keeps cycling the same way. The nav, radio, bluetooth, cd and the sos light error in the cluster. Safety alarks are all disabled and the vehicle is unable to detect or report if objects are near the bumper or sides of the vehicle. The unit stays running (maybe the fan) when I turn the car off and drains the battery.
Vehicle would not maintain speed in 3-4 gear, would go into limp mode. Had to have the transmission replace with only 25,000 miles on the vehicle.
2nd time this has occurred in pouring rain while driving. I have a rag top convertible bmw that when it is pouring rain..water somehow permeates the back of the car and "fries" the electrical components as I am driving.. The first time it happened it fried the onboard ccc at 48,000 miles, and all the components and now it has apparently compromised the replaced parts in the trunk area.. I looked it up and it there is "service bulletin" the federal safety agency id number: 10028770.. And I am sorry but I think this is a safety hazard when I am driving in the rain.. And all of sudden all of my electrical components start to fizzle out.. And the hazard lights are activated..

While passenger is in the vehicle the passenger airbag off light stays lit, meaning that the airbag is off even though there is a person in the seat, that person in the seat in my son that weighs about 225 lbs. My local dealership replaced the whole passenger seat and sensor. Once I got my car back I had the same exact problem. My car was also with the dealership for about 30 days for this issue. Also in the vehicle options for this form my car wasn't on there so my car model is: 2008 bmw m6.
