One problem related to engine and engine cooling has been reported for the 2004 BMW M3. The most recently reported issues are listed below.
Vehicle drops out of gear randomly. As I was taking a left turn, the vehicle dropped into 0 gear and on coming traffic almost ran into me head on. I had no way of moving the car due to transmission being shifted into neutral. This is due to a defective temperature sensor on the smg pump. BMW ignores the issue.
