Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Odometer reading on the cluster and title do not match what the car actually has. I purchased the car from mullins ford of vero beach. Found many problems with the car and found that the mileage true mileage was actually 13,000 miles more. Spoke to two managers and neither of them wanted to do anything about it. I really loved the car and wanted to keep it but for someone to lie and do something fraudulent is not a pleasure I wanted to be apart so I informed them of it and made them refund my money. …”
NHTSA complaint #11302661, filed 2020-01, 75,894 miles“I bought this vehicle from the Mecum auction. It was represented as a vehicle with 2651 miles on the odometer after purchase. I later ran a Carfax and saw that it had upwards of 60,000 miles and had potential odometer. Roll Back. I contacted Mecum and they said they could not do anything about it. The seller who sold it to Mecum was a dealership in Michigan.”
