Example complaints

“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“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. …”
NHTSA complaint #11351469, filed 2020-08, 28 miles“On my way to work, my car alerted me to an electrical malfunction and told me to call for service. When I called my Audi dealership, they told me to bring it in for service the following week. After asking if the car was safe to drive, they told me they wouldn't know unless they looked at the car. After pleading with them, they agreed to an appointment that day. …”
NHTSA complaint #11543147, filed 2023-09“Mid December the day after I purchased my 2019 a6 the 48V starter generator failed while driving with my son in the car. Alerts came up as electronics issue and to pull over. Very quickly it stopped dead in road. They told me it is a known issue, and they have multiple A6s waiting for this part. It has been over a month and still unknown when this part will be available. This should be a recalled item, but is under warranty.”
NHTSA complaint #11503814, filed 2023-01“The car gave me electrical malfunction warning while driving on the highway, then all the screens turned black, and the car completely shut down while driving. The steering was still working, although heavier than usual, and the breaking also worked. The car slow down to a complete stop at the shoulder of the highway. This was very concerning, and thankfully happened close on exit with a shoulder at the side in which I was able to park the car.”
