Reported at 50,000 miles, February 2020 CrashInjury

Car vibrates above 35 miles per hour. It almost feels like something is about to give way or fall apart. I have owned several other vehicles by this manufacturer and have not experienced any like it before. I feels like a bad wheel balancing problem. Wheels have been replaced with those of another car and tires have been replaced but to no avail.

June 2015

The brake and gas pedals are too close. I consistently hit the brake while accelerating. They need to be spaced farther apart, and the brake pedal moved to the left. There are comments all over the internet about this problem and audi service says there is no fix. I have large feet and have never had this problem with any other car manufacturer. I need the NHTSA to get involved before someone gets hurt. This is a very big defect that needs to be fixed.

Reported at 3,700 miles, August 2015

I was driving on a suburban city street in a straight line with no cars or any other obstructions ahead of me or behind me. Without warning, the car engaged its emergency braking throwing my daughter and me forward violently into our seat belts. When I fell back, the dashboard was showing me a proximity warning but again nothing was anywhere near our car. The servicing dealer said they didn't find any error codes and so there was nothing they could do.

Reported at 19,000 miles, May 2016

Engine stalled in traffic and car would not restart. Car was operating normally, pulled up to a red light to turn left on to busy 2-lane highway. Engine began sputtering and car lurched forward.

Car was disabled and stuck in traffic. Car towed to dealer. Dealer diagnosed failed turbochargers. Car had 68,800 miles on it at time of turbocharger failure.
