“The throttle stuck on my '99 Audi A6 2.8 quattro at 70 MPH on interstate I-65 in indianapolis, in. It took both feet on the brake to stop the vehicle and still almost hit someone in the rear (scary). I put the car in park, it red-lined and I turned off the ignition. When I restarted the car the throttle had reset. Fortunately my wife was not driving.”
NHTSA complaint #10062344, filed 2004-03, 75,900 miles“1999 Audi A6 quattro suddenly accelerated. I was pulling into a parking slot at maybe 5 MPH, my foot was lightly pressing on the brake pedal, as I was nearly in the parking stall. The engine was at idle speed. As I coasted into the parking stall with my foot on the brake pedal the engine suddenly and without any prior warning revved up to above 3000 RPM.

NHTSA complaint #10397211, filed 2011-04, 184,700 miles“Driving home tonight my car all of a sudden started accelerating (I drive an Audi A6 1999).

I waited ten minutes or so and tried starting my car. The engine revved to 4 to 5000 rpms so, I quickly shut it off again. I waited again, tried it once more and the car started fine. …”
NHTSA complaint #10381378, filed 2011-02, 140,000 miles“On the morning of november 20, 2010, I was pulling in to a parking space at the local library, approximately 10 minutes from my home. As I was making the turn to pull into the parking space, I heard the engine rev, and the car accelerated as though the cruise control had kicked in and my brake would not stop the car. Rather than hit a car that was parked in front of my parking space, I turned the vehicle to go up a curb and hit a tree. Once the tree stopped the car, I was able to put the car in reverse, back down off the curb, put the car in park, and pull out the key. …”
NHTSA complaint #10372683, filed 2010-12, 110,000 miles“I was traveling on pa route 476 southbound approximately 8:30 pm, maintaining a constant speed of approximately 65 MPH. The thermometer in my car reported an ambient exterior temperature of between 4 and 8 f. The cruise control switch was in the standby position but cruise control was not activated. I began to notice that the car was maintaining speed without depressing the accelerator pedal. In fact, when traveling on level ground, the car accelerated to 80 MPH until I depressed the brake pedal. …”
