Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Our a8 has issues with lag time when accelerating from a stop or a slow speed of less then 10 MPH. The vehicle seems to stop running prior to a full stop and if the accelerator is depressed nothing happens for about 5 seconds. This is extremely dangerous and leaves us at risk of being injured or killed. This issue started just a few months after purchase and has gotten continually worse. We have also encountered this issue even after a full stop and then trying to accelerate from a full stop. It has even happened when driving on an interstate highway when trying to pass another vehicle. …”

NHTSA complaint #11359764, filed 2020-09, 15,000 miles“My alternator failed with electrical malfunction alerts until the car decided to shut down on the highway with my newborn and wife. The bigger issue is I'm being told there is a national shortage for this part with no ETA on receiving the part and that it could be MONTHS until they receive the alternator replacement.My car is in dealership since Dec 6 2022. Today is 01.10.2023”

NHTSA complaint #11506608, filed 2023-02“I was driving yesterday on a highway and the car completely shut down. Got stranded in the left lane with 4 kids in the car - could have been killed.
