In short
- Digital odometers can be rolled back too, with cheap tools.
- Compare the mileage with maintenance records, inspection reports and past listings.
- Wear on the steering wheel, pedals and seat that doesn't fit the mileage is a warning sign.
- For most recent cars, the seller must state the mileage in writing when the title is transferred.
- If the mileage is “exempt” or “not actual” on the title, find out why.
How odometer fraud works
Lowering the mileage raises a car's value by thousands of dollars. Mechanical odometers were wound back by hand; digital odometers can be reprogrammed with tools sold online.
Odometer fraud is a federal crime, but it still happens, especially on private sales and cars that have changed states.
Paperwork checks
- Odometer disclosure: for most vehicles from model year 2011 on, the seller must state the mileage on the title (or a separate form) at transfer, for 20 years.
- Title wording: “Not actual mileage” or “Exceeds mechanical limits” is a brand that lowers the car's value.
- Maintenance records: oil change stickers and invoices show mileage at each visit.
- State inspection records and past listings can show earlier readings.
Physical signs
- Steering wheel, shift knob and pedals worn shiny on a low-mileage car.
- Driver's seat bolster worn or collapsed.
- Brake rotors and tires replaced more often than the mileage justifies.
- Screws around the instrument cluster that have been removed.

About usFrequently asked questions
Can a digital odometer be rolled back?
Yes. It takes specialized tools, but they're easy to find. Don't assume a digital display is tamper-proof.
What does “TMU” or “not actual mileage” mean?
That the true mileage is unknown. The car is worth noticeably less and harder to resell.
What do I do if I bought a car with rolled-back mileage?
Keep all documents and contact your state's attorney general or DMV fraud unit; federal law allows you to sue the person who committed the fraud.
