Q7 Prestige 3.0t

  • Automatic transmission
  • 74,500 miles

My beautiful 2018 Audi Q7 Prestige has a bad engine. And it only has 74,000 miles on it. This should be the car's best time: fully paid off and in great condition. Instead it has a bad engine and I may need to trade it in "as-is" and buy a new car that I can't afford.

The issues are identical to everyone else's issues: #1: The car requires frequent oil top-offs between 10K mile services, #2: The staff at the Audi dealership assure me that this is normal and the cars burn oil, #3: Eventually at around 68K miles I get a cylinder misfire. It is on a remote stretch of highway and very scary. It feels like a flat tire except the flat tire is coming from the engine. I restart the car and it's thankfully working again. #4: At 74K miles I get another cylinder misfire on another remote stretch of highway. Not the "check engine" light remains on and I am nervous about driving my beautiful car anywhere beyond 10 miles from my home. No more weekend trips. #5: I am taking to a mechanic who is probably going to say a new engine is required. Ugh.... So am I supposed to just buy a new car now??? This is so insane. I am so disappointed because I love this car so much. But only 6 years of useful life??? No! Need help.

AUDI -- OIL CONSUMPTION – ENGINE FAILURE

My family’s experience with our 2018 Audi Q7 has been so horrendous, we’re now likely going to be filing a legal action against Audi and its parent, Volkswagen Group of America. Our situation is consistent with what’s been alleged in one or more putative class action lawsuits claiming that the piston rings and associated piston assemblies in various models of Audi/Volkswagen vehicles are defective, causing excessive oil consumption, engine damage, major repair costs, and often engine failure.

In one such lawsuit (that Audi/Volkswagen apparently settled), the Complaint alleges that the engine failure caused by the piston defect could result in, among other things, 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 experience online. Starting at around 60,000 miles, our vehicle increasingly consumed oil that continued to the point that, we soon 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. We’ve been advised that, at this point, in order to make the car drivable, we’d have to replace the engine which likely would cost as much as $27,000. Given what we paid for this car, and the fact that, even if we had the engine replaced, the rebuilt Audi engine might end up having the same issues, we firmly believe this recourse is wholly unacceptable.

If you are reading this note and are caught in a similar situation with your Audi vehicle, and would like to consider joining us in a lawsuit against Audi and Volkswagen of America, please send me an email at: audi.lawsuit@gmail.com. Thanks-
