2018 Audi Q7

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.

Fuel pump failed and is leaking on my 2018 Audi Q7. Audi has confirmed it will need to be replaced at my cost. Audi also confirmed it has an extended warranty to replace the faulty fuel pump on other model years on the same q7 vehicle model, for 150,000 miles. It appears that to rectify the issue, the same part is replaced as on the warranty fix. Why was model year 2018 not included in the warranty if it is the same part?
