Two problems related to crankcase (pcv) have been reported for the 2018 Audi Q7. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2018 Audi Q7 based on all problems reported for the 2018 Q7.
This is a well known issue and multiple people have reported on this issue to Audi. It’s is very common in Audi Q7 models from the year 2017 - 2023 where the pcv valve have a defect and the marker on the front passenger and driver side lights as well are out. These are both very costly repairs that are thousands of dollars that truly hurt the consumer. They know that the 3. 0 l engine had a severe problem with the pcv valve and crack case and they have not warned customers and it’s truly hurting the consumer in this economy. Please file this petition and I bet customers flock as I saw a reddit thread with thousands of people complaining about the same common issue and problem with their Audi Q7.

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 …” (gonzalez v. Volkswagen group of America, inc. 1:21-cv-15026) 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.
