I am reporting suspected odometer fraud on my 2018 Audi Q7 3.0T Prestige (VIN: [XXX] ).

I am reporting suspected odometer fraud on my 2018 Audi Q7 3.0T Prestige (VIN: [XXX] ). Between May 8 and June 13, 2025, while I was the sole driver of the vehicle, Audi dealership service records show an odometer increase of 5,282 miles (from 78,260 to 83,542). However, independently verified GPS trip data from the Audi Connect system confirms I drove only approximately 2,103 miles during this period — a discrepancy of approximately 3,178 miles. The vehicle was serviced at two Penske-owned dealerships: Audi of Arlington (3200 Columbia Pike, Arlington, VA 22204) and Audi of Chantilly (14839 Stonecroft Center Ct, Chantilly, VA 20151). Only authorized dealer diagnostic equipment can alter odometer values. This manipulation resulted in the wrongful denial of my extended warranty coverage and a $37,567.16 out-of-pocket engine replacement. I have a fully documented demand letter with ten supporting exhibits including service records, Audi Connect trip data, and a detailed timeline. The dealerships did not respond to my demand letter.

At my 100k mile inspection it was noted that an engine mount is leaking. With a repair cost in the multiple thousands I checked online and have found this to be an extremely common occurrence with possible disastrous implications.

After the shutdown of 3G network, my 2018 Audi Q7 Prestige lost some great features. Audi USA sent a recall 91CD which is basically the notice that 3G network will be shutting down from 2/22. This deactivates app based features like lock/unlock, vehicle monitoring, vehicle related data etc. When taken to the dealership "Audi Minneapolis" with letter from Audi USA, dealership just upgraded the software but refused to upgrade the hardware. They asked $400 to upgrade the hardware. This is really inconvenient for the customer and also a safety issue as I am thinking. Please look into this and pressure Audi USA to come up with a resolution. Attached is a chat script with AudiUSA. Basically customer has to live with the issue.

Dear Leadership @ NHTSA, On July 5th, I reported an incident of Air conditioner not working on my Audi Q7 car with Dealer- Audi Bellevue, located at 1533 120th Ave NE, Bellevue Washington 98005. Findings from the service team was, faulty Control Module and it was replaced. However, this replacement did not fix the problem. Further Investigation led to puncture in the Condenser as the cause. I was told the Condenser had to be replaced. I spoke to my service advisor and Supervisor of the service advisor. My question to them was “How can the condenser get punctured, which is under the hood of the car. My car never met with any accident”? Per Dealer Supervisor, While driving rocks from the road, can make its way through the front grill and make a hole on the Condenser and this is a known issue. My concern is, if this is a known problem, why is Audi still sticking to this Design where it can let rocks pass through the front grill to make a dent on the Condenser. This is causing a huge inconvenience/hardship to customers like me. I had to spend $1,542.62 for the condenser replacement(though I had a Platinum extended warranty) and had to leave my car at the workshop for 11 days. Now that the Condenser is replaced and working fine, the issue does not resolve here, rocks can potentially come through the front grill and can make a dent on the condenser again. This is still an OPEN issue. If that happens again, I will have to go through the same cycle of hardship/hazard/inconvenience. From inspection standpoint, the punctured condenser should be available with my Dealer. I have not made a claim through insurance, so no inspection is made on this condenser. I am not certain when the rocks would have puncture the condenser and there is no indication when the condenser was punctured. Since I noticed my Air conditioner not working on June 27th, I believe this incident of condenser puncture could have happened a week before.
