BMW M6 Problems

During tight, slow speed turning, a rubbing noise can sometimes be heard from the rear of the car. This noise is likely coming from the clutches in the limited slip differential. If the noise persists, the differential fluid can be replaced with a special oil available from BMW. On higher mileage vehicles, this noise may never be eliminated unless the differential is replaced.

Due to a manufacturing process error, the oil pump driveshaft could separate from the pump rotor. Separation of the pump's rotor could lead to a sudden loss of oil pressure causing the possibility of complete engine failure, resulting in an engine stall-like condition, increasing the risk of a vehicle crash. Dealers will replace the engine oil pump to correct this concern.

The insulated 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. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.

this car is the shiz

My M6 for the most part is my favorite car of all time, and ive had over 100+ vehicles. I`ve had it doing 160 MPH before having to slow down for traffic on the thruway, which showed how awesome the brakes are, on that car.
