U.S. Odometer Fraud Statistics (2026)

Key statistics at a glance

How Common Is Odometer Fraud in the United States?

Odometer fraud is growing, not shrinking. Carfax's December 2025 analysis identified roughly 2.45 million vehicles on U.S. roads with a suspected odometer rollback — a 14% increase in a single year. For comparison, the same dataset grew only about 4% between 2023 and 2024, so the 2025 jump represents a sharp acceleration.

The National Highway Traffic Safety Administration (NHTSA) maintains a separate, long-standing estimate: more than 450,000 vehicles are sold each year with false odometer readings, costing American car buyers over $1 billion annually. That estimate, based on NHTSA's odometer fraud research, was still being cited by NHTSA and state consumer-protection agencies as of 2026.

The two figures measure different things. NHTSA counts fraudulent sales per year; Carfax counts vehicles currently in operation whose reported mileage history contains a rollback. Together they indicate that roughly 1 in every 100 used-car transactions involves some form of mileage misrepresentation risk.

What Odometer Fraud Costs Buyers

NHTSA puts the aggregate cost of odometer fraud at more than $1 billion per year for U.S. car buyers. At the individual level, Carfax's December 2025 data shows vehicles with a rolled-back odometer averaged a loss of around $3,300 in value; its 2023 and 2024 reports used a figure of about $4,000. The U.S. Department of Justice has separately estimated the average consumer loss at approximately $4,000 per vehicle once more-frequent repairs are factored in, a figure cited by state consumer-protection agencies such as the Georgia Attorney General's office.

The purchase-price premium is only part of the damage. A rolled-back vehicle has more wear than its maintenance schedule assumes, so timing belts, brakes, transmissions, and other mileage-based service items tend to fail earlier than the new owner expects. Warranty coverage and insurance valuations tied to the odometer reading can also be affected.

Why Digital Odometers Did Not End Rollbacks

Mechanical odometers, which could be rolled back by physically spinning the number wheels, largely disappeared in the 2000s in favor of digital displays. That transition was expected to make tampering harder. The opposite happened: Carfax reported in December 2025 that tampering became more common as vehicles moved to digital odometers, because inexpensive, widely available tools can rewrite the mileage value stored in a vehicle's electronic modules. In its 2024 report, Carfax noted the process can take a bad actor only seconds and leaves no mechanical trace.

What has improved is detectability after the fact. Mileage is now recorded digitally at many points in a vehicle's life — state title transfers, safety and emissions inspections, service visits, and insurance events. NMVTIS, the federal title database operated under the U.S. Department of Justice, captures the odometer reading each time a state titles a vehicle. A rollback that goes unnoticed at sale often shows up later as a mileage sequence that decreases over time in these records.

States With the Most Odometer Rollbacks

The most recent Carfax release with full state-level counts (December 2023) put California first with about 469,000 suspected rollback vehicles, followed by Texas (277,000) and New York (100,000). Nine of the ten states with the most affected vehicles saw increases that year, and large used-car markets with higher vehicle values tend to attract more of this fraud.

Growth patterns have shifted since then. In December 2024, Carfax reported the largest one-year increases in Virginia (+11.7%), Arizona (+8.0%), and Florida (+6.4%). In December 2025, the fastest-growing states were Montana (+33%), Tennessee (+30%), Arkansas (+28%), Oklahoma (+25%), Kansas (+24%), New Jersey (+21%), and Florida (+20%) — Florida being the only state to appear on both lists.

Federal Odometer Law: Disclosure, Tampering, and Penalties

Federal odometer law lives in Chapter 327 of Title 49 of the U.S. Code. Under 49 U.S.C. § 32703, no one may sell or install a device that makes an odometer register different mileage than the vehicle was driven; disconnect, reset, or alter an odometer intending to change the registered mileage; knowingly drive a vehicle with a disconnected or non-working odometer with intent to defraud; or conspire to do any of these things. Section 32705 requires the seller to give the buyer a written mileage disclosure each time ownership transfers.

In a final rule published November 26, 2019 (84 FR 65017), NHTSA made two significant changes. First, states may adopt electronic odometer disclosure systems without prior NHTSA approval, effective December 31, 2019. Second, effective January 1, 2021, the age at which vehicles become exempt from federal odometer disclosure was extended from 10 years to 20 years, starting with model year 2011 vehicles. A model year 2011 vehicle therefore requires mileage disclosure at every transfer through 2031; model year 2010 and older vehicles remain under the previous 10-year rule.

Penalties are set by 49 U.S.C. § 32709: civil penalties of up to $10,000 per violation (up to $1 million for a related series of violations), and, for knowing and willful violations, criminal fines plus imprisonment of up to three years. Defrauded buyers can also sue privately for three times their actual damages or $10,000, whichever is greater, plus attorney's fees. NHTSA's Office of Odometer Fraud Investigation conducts criminal investigations that the Department of Justice prosecutes.

How to Check a Used Car for Odometer Rollback

Start with the paper trail. An NMVTIS vehicle history report includes the most recent odometer reading recorded when a state titled the vehicle, and NMVTIS lists the odometer reading among the five key indicators consumers should review before buying. Compare the current dashboard reading against titles, inspection records, service invoices, and window-sticker maintenance reminders — any point where the sequence decreases is a red flag. VIN Lookup (free-vin-lookup.com) offers free VIN decoding to confirm a vehicle's model year and build specifications, and an optional paid ClearVIN report that draws on NMVTIS title and odometer records.

Then check the physical evidence. Heavy wear on the driver's seat, steering wheel, pedals, and shift knob on a car claiming low mileage is inconsistent with the odometer. On pre-digital vehicles, misaligned or crooked odometer digits suggest mechanical tampering. For any vehicle, a pre-purchase inspection by an independent mechanic can compare component wear against the claimed mileage.
