I have received two "cylinder misfire" notifications. The first occured in December 2023 on a remote stretch of freeway. The second occured in June 2024 on a remote stretch of highway. In both cases, I immediately lost power and put myself and cars around me at risk because I had to pull over onto the side of the road to re-start the car. After the second incident, I now have no confidence in taking my car, only 6 years old and with 74K miles on it, out of the city and into the countryside. The symptoms of this issue include frequent oil burn / oil top-offs. My car requires a quart of oil every 200-300 miles. There are no leaks in my driveway. The leaking all seems to be coming from the cylinders. I am taking my Q7 into a mechanic, again, next week and I am concerns the solution will be "new engine" which costs more than the car is worth.

The contact owns a 2018 Audi Q7. The contact stated that while driving at an undisclosed speed, the low oil warning light illuminated. In addition, the contact stated that the oil level was topped off every 700 miles. The vehicle was taken to the dealer where it was diagnosed with a failed piston and excessive oil consumption. The contact was informed that the piston needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 75,000.

Noticed a lower level of coolant (below the MIN mark) at the coolant reservoir - checked with mechanic and was told there is a slow coolant leak at the one of the water pump seals (which has corroded). Need a water pump replacement. Was told it is a very common occurence with these cars - but was surprised to experience this issue on a car with less than 20K miles driven.

We have had major problems with our 2018 Audi Q7 that are consistent with allegations made in various lawsuits against Audi and Volkswagen Group of America for alleged defects with Audi piston rings and piston ring assemblies. The defects have purportedly caused excessive oil consumption, engine damage, and engine failure. As noted in one such lawsuit (that apparently settled), the engine failure caused by the defective Audi piston ring and piston assemblies could result in sudden loss of power to the engine. -??It goes without saying that a sudden loss of power poses a clear-cut safety risk-?"it can prevent the driver from accelerating, maintaining speed, and even adequately controlling the steering wheel, engaging the brakes, all of which drastically increase the risk of collisions -??-?? [XXX] v. Volkswagen Group of America, Inc. {XXX]) The problem with our Audi is consistent with the reports by plaintiffs in these lawsuits, as well as other Audi owners-?"including Q7s-?"who have shared their experiences online. Starting at around 60,000 miles, our vehicle increasingly consumed oil until eventually, we needed to add a quart of oil less than every 600 miles. And that-??s despite our: 1) having followed all of the required oil change and other related maintenance standards published by Audi; and 2) having replaced the car-??s CCV valve and PCV breather, which we were told sometimes corrects the problem. Most recently, in December 2023, I was driving with my children in the vehicle, and the engine started sputtering and laboring. Then the check engine light appeared. I was able to drive the car home but have been advised that, in order to make the car drivable, we-??d have to replace the engine. Obviously, even if we have the engine replaced, the rebuilt Audi engine could have the same problems. Given the risk that the affected Audi engines will fail in vehicles traveling at high speeds on U.S. highways, the NHTSA should investigate this matter immediately.

coolant leaking @ 50K miles and also their warning system is not as effective. I got into a fender bender 2 months in owning the car as brand new.

While driving, car stops and message " Drive System:Malfunction! Please Contact Service" comes on along with check engine light and message indicator.

Water pump failure. This can lead to catstrophic engine failure if not addressed. Dealer has confirmed the failure. No fault codes appeared in any scans. Only warning signs were rapid coolant loss & the smell of burning coolant.

- Aurora, IL, USA

Engine coolant leak reported only at around 30K miles. Leak detected and fixed at owners cost.

At approx 56,600 miles I received a low engine coolant error on my vehicle. Upon inspection, all engine coolant was gone from the tank. Engine coolant was refilled by me at home. The next day, I received a low oil error on my vehicle. Upon inspection, the oil was below the minimum level. 1 quart of oil was added to my vehicle and we promptly took the vehicle in for inspection as this did not seem like a coincidence. Upon inspection at Motor City Euro Repair, it was noted that the water pump was leaking causing the engine coolant and oil levels to decrease. Water pump replacement required, which should typically not be a required repair until 100,000 miles. Audi is aware of this issue, but no recall has been made. There is also a class action lawsuit for this issue, but the 2018 Q7 Prestige 3.0 is not part of the vehicles in the suit. Total cost of repair was $1,375 as the vehicle is 6,600 miles out of warranty. Again, this is a know Volkswagen/Audi issue and Audi US is not recalling.

1.Interior color light bars: These light bars developed inconsistency. Audi repaired the inconsistency however now the light bars only display pink (not white) during start up. The dealership tried telling me it-??s not pink, then claims to be color blind. I have artiest friends who maintain the color is pink. 2.Engine start-stop: Dealership confirms the Q7 will shut down as part of the start-stop feature before the vehicle has stopped. I explained to the dealership that the Q7 speedo claims moving 1 to 2 mph faster than it is moving. Therefore, during slow speed braking, stop sign, the Q7 will shut down before it stops moving. Without the engine on, the Q7 will lurch to a stop or and forcing the transmission to turn. 3. Low oil light comes on between oil changes sometimes.

Water pump stopped working properly, creating hazardous situation with my car. Had the car overheated and stopped working while driving, this could have been catastrophic. The only symptom was loss of coolant and resulting warning message from the car. I took it to an independent service center, who diagnosed the problem and replaced at my own expense of $961.07.

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".

Kept light appears on dash that add 1 qt of oil for 6 times. Before this light appears, car always suddenly stopped while im driving or parked. Last saturaday 1/11, my car was suddenly stopped on highway and engine was running and so loud after car stopped but cannot change any gears for few seconds. I'm so frustrated and scared to operate this vehicle. I went to Audi service but they don't found any problems and refilled oil again. In my 6 times of this experience, light will be appeared and car will be stopped while operating again. Must be fixed this matter by Audi

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.

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. Their only work around is to engage the vehicle into "sport" mode. That mode helps with the response. Basically if, I step on the gas peddle, I should expect it to drive and be responsive and not hesitate. Having that hesitation, make it very difficult to determine when accelerate.
