As per the below BMW service bulletin, I have a defective sunroof cassette as it doesn't have adequate water management and causes water to leak into the front and rear compartments and can cause electrical control modules to get wet and become damaged. This is a safety hazard caused by the potential flooding. Si B 54 06 06 special roofs November 2006 technical service this service information bulletin supersedes S.I. B54 06 06 dated August 2006.

2004 BMW X5 steering vibrates and pulls slightly to the left, cigarette lighter came apart, center console opens on its own. ** answer required*** when the consumer looked under the vehicle, he noticed one side of the vehicle was lower than the other, which may have been the cause of the vehicle pulling to right and the horrendous vibration. The seat frame was loud because it moved back and fourth and did not fully lay flat. The sunroof leaked. The lights flashed on and off at regular intervals, the left rear window was inoperative, the right rear door never opened, the horn starting blaring on and off for no reason. The audio controls on the steering wheel did not work. The key sometimes did not unlock or lock the doors.
