Electrical system: 12v/24v/48v battery: cablesReported March 26, 2012 · 367,682 vehicles affected
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.

Risk
Power assist braking performance could be adversely affected. In extreme cases there could be a complete loss of power assist braking. An unexpected reduction or loss in power braking assist may increase the risk of a crash.
Remedy
Bmw will notify owners and dealers will repair the vehicles free of charge. The safety recall began on november 24, 2010. Owners may contact bmw at 1‑800‑525‑7417.

Recall number 10V446000 · Recall details

Power train: automatic transmissionReported November 1, 2005 · 240 vehicles affected
What is wrong

Remedy
Dealers will repair and replace the automatic transmission guide plate free of charge. The recall began on november 30, 2005. Owners may contact bmw at 1‑800‑332‑4269.

Filed Jul 21, 2006 · Electrical · IN

I bought a new 2005 bmw 645i.and it had computer problems. The dealer said the manufacturer usually fixed problems in 60-90 days. It has been 18 months and the on board computer has problems with the entertainment, and bluetooth. The computer continues to play cd's after the engine is shut off. The dealer ignored the problem for months until I said the car would need to be bought under the "lemon law'. They will not replace the vehicle because they now say all 650 and 645 models have similar problems and they cannot guarantee another vehicle would perform without problems. The dealer and bmw northamerica are aware of the problem.

Filed Apr 26, 2006 · Fuel system · NY

My bmw 745i has been in the shop repeatedly to fix a problem with the gas reading mechanism. The car tells me there is gas when there is none or vice versa. Twice the car has completely stopped working having to be towed. The most recent time was this morning while driving on the highway the car just stopped. The gas gauge indicated I had a half a tank of gasoline whereas it turned out it was completely empty. I was under an overpass, alone with cars zipping by on my left, a wall to my right and no one to stop me from being struck from the rear! On five separate occasions the faulty part was allegedly changed. First to the right side and then to the left (whatever that means) it still does not accurately read the gasoline.

Filed Jan 6, 2006 · Brakes · 8,323 miles · CA · crash
