NHTSA Complaint #11668138 — 2014 AUDI A6

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)
