the first indication of an issue was oil consumption. It was using more oil than usual around the 70K mile mark. Then it started misfiring, and soon after a knocking noise coming from the engine. There are no check engine light on, after bringing it in for diagnostics, it read that it was a spark plug, once they got into the engine they discovered the cylinder had been stripped from the piston. Yes the diagnostics came from our foreign car mechanic. no, it has not been inspected by the manufacturer or police. Just the symptoms. sometimes the light would come on, and then it would go off. At this point it is off. All of this started in the fall of 2025.

I am filing a complaint concerning serious safety risks associated with my 2020 Audi Q7 (VIN: [XXX] ) purchased as a Certified Pre-Owned vehicle from Audi Dominion San Antonio. It is currently under service at Audi Central Houston, where multiple concerning events occurred. Timeline and Issues: - Initial diagnosis identified a fire-damaged electrical harness, estimated at $1,400 for replacement. - After repair attempts, the vehicle began smoking, and the diagnosis expanded to include additional compromised electrical lines. The revised quote skyrocketed to $4,700 (later reduced to $3,100). - After nearly two months in service, I was informed that the AC compressor is now deemed "bad" due to debris from the harness, an issue not mentioned in previous inspections. Safety Concerns: 1. Inconsistent Diagnosis: There was no mention of compressor damage during initial assessments. This late-stage discovery indicates negligence or potential additional damage during servicing. 2. Risky AC Activation: A technician attempted to clean the compromised AC compressor and activated the system, a procedure that is dangerous given the debris. This could lead to refrigerant leaks and electrical shorts. 3. Conflicting Statements: Audi Central Houston claims the compressor was previously damaged but also attempted to restore it. Such contradictions raise serious concerns about service integrity. 4. Certified Pre-Owned Credibility: The emergence of these costly issues questions the reliability guarantees of vehicles sold under Audi's Certified Pre-Owned program. Given that the vehicle began smoking shortly after being parked and had not undergone prior electrical work, I underscore the severe safety risks posed by potential electrical fires and undisclosed damage. These issues could endanger lives and property if not properly addressed. I strongly urge Audi USA and the NHTSA to investigate this matter for potential technical service bulletins or recalls, especially fo INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
