The number of cars on the road in the U.S. with rolled back, fraudulent odometers rose by 14 percent in the past year.
A new study from CARFAX estimates that 2.45 million vehicles have odometers that have been rolled back. The 14 percent increase in 2025 followed a 4 percent spike between 2023 and 2024.
“Odometer rollbacks occur when someone alters the mileage stored in a vehicle’s electronic systems to make it appear less driven,” said Faisal Hasan, Vice President of Data Acquisition at CARFAX in a press release. “As modern vehicles have transitioned from mechanical to digital odometers, tampering has unfortunately become more common due to the wider availability of inexpensive tools. At the same time, a car’s mileage is now recorded more often, which helps us identify discrepancies and better protect consumers.”
CARFAX estimates the loss in value from the rollbacks at $3,300.
California had more than 530,000 suspected vehicles with rolled back odometers. Texas had an estimated 333,000. Florida and New York were each slightly above 100,000.
Montana, Tennessee, Arkansas and Oklahoma saw the sharpest rise in suspected rollbacks in the past year.
