“Subject of Complaint: Severe odometer fraud, mileage tampering, and title misrepresentation by the selling dealership: Phenix Motors, LLC ([XXX]), operated by [XXX]. The Discrepancy: The vehicle was sold to me with a falsely represented odometer reading. Subsequent electronic diagnostics and vehicle history reports reveal that the actual mileage is severely discrepant from the mileage disclosed on the official bill of sale and title paperwork provided by Phenix Motors, LLC. The dealership has since explicitly refused to participate in state-level consumer mediation with the Mississippi Attorney General's Office.Current Status & Evidence Location: The vehicle is currently completely inoperable with a dead dashboard/ECM display. On XXX, the financing lender, Magnolia Federal Credit Union, executed a repossession of the vehicle. Under the FTC Holder Rule, the lender is fully aware of the fraud claims. The physical car and its electronic control modules (the core evidence of the fraud) are currently being held by the lender's agent: United Auto Recovery (Account reference partial VIN: [XXX]).State Action & Reference History:Mississippi Attorney General's Office:…”
