On the highway, my a6 turned perpendicular and was hit by a semi truck. Speaking with the audi representatives they did not understand how this could happen. Is there a defect that would allow the car with a quattro system to make such a dramatic turn travelling at 60 miles an hour?

Reported at 58,000 miles, January 2018 Crash

Audi brake guard activated spontaneously because the car sensed an impending impact with a vehicle in front of me. However, there was no vehicle in front of me, but the brake guard applied strong braking action on an open road, bringing me to an immediate stop. Had there been a car behind me, it would have likely hit my vehicle, since I came to a sudden stop on an unobstructed roadway for no reason.

Reported at 4,400 miles, April 2015

Exhibits an alarming tendency to weave from side to side without a steering input. This occurs without a change in steering wheel position, vehicle speed, or change in road surface or prevailing wind direction. It is more pronounced at highway speeds and when wheel is centered at 12 o'clock but does occur at all speeds and steering vectors. Audi dealership notes the problem and blames the new electric steering system but states it is a "characteristic" of the system and is not a defect.
