“My 6 week old Audi A6 was totaled when I was driving 20 MPH! I looked down to check my odometer, and within that time, no warning signals , brakes, etc. Alerted me! This car had all the bells and whistles! That morning I was on a tree lined drive to the tennis courts! No alerts! Hit a tree and all air bags deployed! Tremendous impact for 20 MPH! I was all banged up, car totaled! I am still in disbelief...thought I had the world's safest car. Has anyone else had a problem???”
NHTSA complaint #11253328, filed 2019-09, 750 miles“I acquired this car (2.0t) two nights ago and on three occasions (so far) the engine completely stalls when the car comes to a stop. Not the typical auto on/off feature function. I have to restart the ignition and put the car in drive again. Once, even in the middle of rush hour traffic. So far, the only consistent scenario is when I am on the second leg of a trip. For example, I get in the car at my office, drive to a store or daycare. Get back in the car, start up, drive a couple of miles and the car shuts down at a complete stop. …”
NHTSA complaint #11299645, filed 2020-01, 150 miles“At a stop light the engine will shut off completely requiring you to restart the car. This happens intermittently and happens when the auto on/off is on or off. Leads to dangerous situations when in city traffic or stopped at a red light on highway. Two trips to Audi and there are no error codes on the engine to diagnose the issue. Makes for very nervous driving when every stop light may cause your car to stall. Most recent issue the car would re-start and immediately stall, and then started shaking violently.”
NHTSA complaint #11329769, filed 2020-06, 2,500 miles“Stop engine oil pressure too high light comes on dealer does not have solution. Engine could blow during operation and cause accident. Vehicle recall needed”
NHTSA complaint #11185595, filed 2019-03, 100 miles“This vehicle suffers from a sometimes dangerous acceleration lag. The time it take between pressing the gas pedal and the time the car starts to move is excessive and in certain situations, dangerous. It's especially evident in conditions where you're trying to accelerate from a low RPM speed (slow traffic, california stop, etc) to join faster traffic or merge in. A perfect example is trying to go from a slow moving highway lane to a faster one. You pick your spot, then go for it. The car sits for 1-2 seconds...then it goes. The first few times it happened it was dangerous. …”
