Recalls 3
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.

Service brakes, hydraulic: power assist: vacuum
- What is wrong
- Bmw is recalling certain model year 2004-2010 5-series, 6-series, and model year 2002-2008 7-series vehicles. A check valve of the brake vacuum pump may leak a small amount of lubricating oil. Over time this could result in contamination of the brake booster.
- Risk

- 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.

- 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.

Passenger airbag lamp is on and stays on after technician at the bmw service center reset the vehicle's computer (cleared faults). Vehicle did not get into situation which would trigger airbag deployment, but potentially the passenger frontal airbag may malfunction and render the passenger airbag inoperative.
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.
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.
Dt: the contact stated the brakes failed while driving . The pedal went to the floor, resulting in an accident. The vehicle went over the curb and hit a parking pillar. The undercarriage was damaged. The contact reports hearing squeaking noises coming from the brakes two weeks prior to the incident. The squeaking noise occurred only while driving slowly at 5 to 10 MPH. The dealer said the brake pressure sensor was bad. The dealer plans on contacting bmw to see if the repairs will be covered under warranty. A police report was taken.
