I am writing to formally file a complaint regarding persistent mechanical failures and safety concerns with my 2014 Audi A6, VIN: [XXX] , which have resulted in significant repair expenses, inconvenience, and potential safety hazards. Despite having the front brakes and sensors replaced in the previous year, I recently experienced brake warning lights and related malfunctions. According to the most recent service report from Audi Bethesda (Repair Order [XXX], dated May 9, 2025), it was discovered that the incorrect brake pad sensor had previously been installed and that connectors were not properly secured. Additionally, the repair team found further issues with the ABS sensor and rear brake pad sensors—indicating an ongoing pattern of misdiagnosis and improper installation by authorized service providers. More concerning is the failure of the vehicle’s fuel system, including the fuel pump and filter, which were replaced at considerable expense. According to the repair documentation, there were still unresolved low fuel pressure faults present even after parts replacement. The technicians cited potential metal contamination in the fuel meter valve (N290), which could require full fuel system replacement—an unacceptable situation for a vehicle that has already undergone such costly repairs. After further internal investigation by Mitch Carr’s Auto Service several other concerns were brought to my attention. 1)Battery left to die 2)Fuel filter replaced 3)Glow Plug Replaced 4)Injector Seal Replaced 5)Re-Gen DPF procedure to clear faults 6) Rubber Stem on Tire Replaced INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased a 2014 Audi A6 2.0T Quattro premium plus on November 15, 2024 with 99,141 miles. I got the 14 day dealership extended warranty, which covered powertrain systems. After 3 days of driving exactly 103 miles the oil light came on my dashboard telling me that the oil was low. I immediately brought it back to the dealership and their mechanic look at it, he said there was nothing wrong and changed the oil so it should be good now. I drove it another 3 days 136 miles this time, and the oil light came on once again. Brought it back a 2nd time to the dealership’s mechanic. After about a week, we heard back and they told us he still couldn’t find anything wrong, but agreed that for some reason, the engine is consuming oil more than it should be. At this point we go to an actual Audi dealership where they tell us that the pistons and turbo were the problem so they would have to rip apart the engine and seal everything back up. At the time we purchased the vehicle on top of the 14 day dealership warranty we also purchased an extended warranty by a company called integrity warranty LLC. Our warranty company decided that they were not going to cover the cost of the parts and labor in order to fix my Audi, because they said it was a pre-existing issue prior to us purchasing the vehicle which we had not heard of before, or even seen on the Carfax report. On February 25 I was driving at night 25 mph and I came to a red light stopped my car and began smelling a very strange smell. Saw a lot of smoke coming from the exhaust in the back, the dashboard lights began flickering, the steering wheel start to shake, and then the car just shut down. Now I am without a vehicle, the dealership will not help us, the warranty company will not help us, and I now have to purchase a new car while still making payments on the Audi that doesn’t work.

My car was manufactured with defective pistons. The pistons are resulting in reduced oil pressure in my engine, which can result in a sudden loss of power. I had my engine inspected, and the attached photographs depict that the original pistons that shipped with my car caused scoring to the cylinder walls which is causing metal pieces to collect in my engine. In addition, Volkswagen Group of America, Inc. acknowledged that the pistons need to be repaired in my car, and quoted the repair using an updated design, so they are aware of the issue and have knowledge of it. While the defect existed during the warranty period, VWGoA refuses to repair or replace my defective engine under warranty.

The electronic steering system on my Audi A6 failed without warning, locking my steering wheel in place. A review of on line message boards for Audi owners indicates this is a systemic problem, and has, for some owners, actually locked their steering while driving. This did not happen to me, but prior to locking, my car instantly transitioned from steering with no issues to almost becoming undrivable before I could get to a repair shop.
