“I have attached a complaint which sets for the odometer fraud resulting in severe damage to my engine. I have also attached mileage discrepancies and the documentation created and maintained by AutoNation Ford Valencia which records my odometer at 26,250 in September 2022 and after taking my vehicle in for service of the air condition, I received it back with an odometer reading of 25,134 which appear on the odometer. Please review my complaint and supporting documentation.”

I brought my vehicle into your service department, where I was informed by the service representative that the problem was related to the spark plugs. After paying $600 for what was purported to be a fix, I retrieved my car, which drove fine for about a week before the same issue recurred. The engine began shaking again, and the check-engine light reappeared. I promptly scheduled another appointment, explicitly mentioning that the problem was identical to the previous one.
