Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“At times, the stop-start system seems to falter when the vehicle has slowed to almost a full stop, but not quite. If I try to accelerate I get a few seconds when nothing happens. I feel that it is either a transmission caught between shifts or an engine falter. I have mentioned this to the dealer, but was told that that's how it is .”
NHTSA complaint #11406681, filed 2021-04, 20,000 miles“Our Q7 3.0t prestige engine blew while driving and left us stranded on a country road at 12:45 in the morning. Then to add insult to injury, after fighting with Audi care for the last month they only agreed to reimburse us $200 out of a $525 tow bill because we didn't call them to schedule the tow. We didn't even know that service existed and at 12:45 am with a car that just died and was in the road, we just wanted to contact the closest place and get our car off the road as we were worried about our safety and getting hit by another vehicle.”
NHTSA complaint #11203914, filed 2019-04, 14,000 miles“When attempting to crossover a busy intersection, and trying to determine the distance between the oncoming traffic and myself, the 2018 Audi Q7, has a hesitation before the vehicle starts it acceleration. I have had two occasions where the vehicle just would start a slow acceleration but would hesitate before engaging at its higher acceleration. This causing the oncoming vehicles nearly hitting my vehicle. I have taken this to the local Audi dealership and said that is normal. I validated the operation, when they let me test a new Audi Q7, and had similar or worse symptoms. …”
NHTSA complaint #11093960, filed 2018-05, 11,000 miles“#1 cylinder lost compression causing car to almost immediately stop while driving 78mph on the interstate. Car was towed back to manufacturer where I bought the car. The car 2018 Audi Q7 has 68,000 miles, all servicing of vehicle was done at dealership where I bought the car. Never any problems with engine except the occasional need for engine oil requiring being topped off.”
NHTSA complaint #11672505, filed 2025-07“We were driving down the expressway when the car began to vibrate. We pulled over and had lights on the dash. We had it towed to a dealership where it was diagnosed as a burnt valve and ruined motor. I believe a new Audi engine quote was around $26,000. We took very good care of this car. This is a common issue and will become more common as these engines fail.”
