What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

I was rear-ended at a slow speed. I was stopped at the time. The driver who hit me was decelerating hard. Damaged to rear bumper. When I got back in the car, I realized that telescoping steering column had been pulled toward me. This would have been bad had I been shoved into the car in front of me and the airbags deployed too close to me. Luckily, this did not happen.

New factory brakes make very loud audible screeching sound when coming to a stop.this happens just before coming to a complete stop and sometimes in the beginning of breaking. Mechanic has worked on this issue several times and reordered brakes from local audi dealership and it is still making the sound.

Engine malfunction prevented the vehicle to engage and a significant lag. Correction of the failure has been attempted twice and a third attempt to correct malfunction is currently in progress with no movement as of yet. Gas tank has been drained and refilled and did not correct issue. Definitely not a gasoline type issue.
