When accelerating out of a toll booth, the engine lost all power just as I changed lanes in front of large truck. Fortunately, there was a pull-out on the left side of the road. If I had not been able to quickly pull over, the truck would have likely collided with my car. Turning of the engine and restarting it temporarily cleared the problem. It would reoccur whenever I used full throttle and the engine hit 5000 RPM. The problem turned out to by a sticky super-charger bypass valve. It is a well known problem, so much so that the dealer always have the parts in stock. Loosing all engine power is potentially very dangerous - BMW should fix this.

-stalling when changing from reverse to drive. Has also stalled once on the interstate. -RPM's keep revving between 3000 & 5000 when I hit 55-60 mph. Once I pass 60 mph the RPM's decrease to a reasonable level. This happens everyday without fail.

My 2002 MINICooper S has some engine management issues that have resulted in several close calls in traffic situations that I feel are unsafe, and have yet to be resolved or definitely addressed by the manufacturer. The most severe issue is a total loss of engine power after acceleration on clean dry pavement. Loss of power is usually in 1st gear an can last several seconds. I beleive this to be a problem not unique to my vehicle.
