NHTSA Complaint #11628004 — 2009 BMW R 1200 GS

While attempting to pass a car on the highway, the engine suddenly lost power, forcing me into a perilous maneuver to reach the breakdown lane at highway speed. Following vehicle recovery and upon further inspection, I discovered that both plastic throttle body cam pulleys had broken in half, completely disabling throttle control. There were no warning lights or symptoms indicating this failure was imminent. In my research to fix the issue, I found that this problem is more common than I realized and poses a serious safety risk.
