Selling a car with a broken odometer or unknown mileage

That one honest line is the whole trick. What gets sellers in trouble isn't a dead odometer. It's writing down a number they know is wrong.

The federal rule in plain terms

The odometer law is federal, so it follows the car into every state. Under 49 U.S.C. 32705, a seller:

• hands the buyer, in writing, the total miles the odometer shows
• must say the true mileage is unknown whenever they know the number on the dash doesn't match how far the car has gone
• can't put anything false in that disclosure

Two more parts of the same law shape the paperwork. A buyer who is buying the car to resell it can't accept a written disclosure unless it's complete. And a state won't license a car that changed hands until the new owner hands in the previous owner's title carrying a mileage statement. So the mileage statement matters to the buyer too: without it, the new owner can't license the car.

Why all this? The federal rule says it exists to help buyers judge a car's condition and value (49 CFR 580.2). Mileage is one of the first things anyone uses to price a used car, so the law treats it as something a seller must get right or flag.

The three things you can certify

The regulation, 49 CFR 580.5, gives a seller three options. Pick the one that matches what you actually know.

Whichever box applies, you still write down the reading at the time of transfer, in whole miles with no tenths, on the title itself or on a reassignment form. Then the buyer signs the disclosure, prints their name and hands you a copy. Keep that copy.

What it looks like on an Ohio title

Ohio shows how the box you check turns into words on the next title. Under R.C. 4505.06, when the seller marks the mileage as not actual, the clerk enters "nonactual: warning - odometer discrepancy" after the mileage. When the seller marks it as past the mechanical limit, the clerk enters "exceeds mechanical limits."

The Ohio BMV lists an Odometer Disclosure Statement, form BMV 3724, if applicable, among the title documents, and Ohio requires a notary on the title.

A practical path when the odometer is broken

1. Write the reading as it appears. The rule asks for the odometer reading at transfer. If the display shows nothing at all, ask your title office how it wants the mileage line filled before you sign anything.
2. Check the not-actual box. If you know the reading isn't the real mileage, say so. That's the disclosure the law asks for.
3. Don't estimate. Virginia's DMV tells sellers to enter the actual odometer reading and not to guess or estimate (Virginia DMV). A guess that looks precise is exactly the kind of false statement the federal law bars.
4. Keep the title clean. Missouri says no correction fluid or erasures on the title (Missouri DOR). Montana wants blue or black ink and warns that white-out or crossed-out entries make the title void (Montana MVD). Fill in the odometer lines slowly, once.
5. Tell the buyer in writing why. A short line on a bill of sale, such as "odometer stopped working, actual mileage unknown," backs up the box you checked. Our as-is guide covers writing up known faults.

If the odometer was repaired or swapped

A replaced instrument cluster is a common reason the numbers stop matching the car. Federal law allows the repair but adds a step. Under 49 U.S.C. 32704, when an odometer is serviced or replaced and the mileage can't stay the same, the owner has to fix a written note to the left door frame showing what the mileage was beforehand and when the work happened.

If that sticker is on your car, point the buyer to it. If the cluster was changed and you know the reading no longer matches the car's true miles, mark the mileage as not actual.

Older cars may skip the disclosure

Some states print an age limit on their own pages, and they don't all match:

• Hawaii and Oregon tie the requirement to model year 2011 and newer, for the first 20 years.
• Nevada asks for the reading on 2011 and newer cars.
• Iowa's line is nine model years: anything that age or newer needs the statement.

Federal law still asks the seller for a written mileage disclosure, so ask your title office before you leave the odometer section blank.

What happens if someone lies about mileage

The penalties are why the "unknown" box exists. It's illegal to disconnect, reset or alter an odometer in order to change the miles it registers (49 U.S.C. 32703). A breach of the odometer law or its rules can bring a civil penalty as high as $10,000 for each violation, with a $1,000,000 ceiling for a related series. Doing it knowingly and willfully is a crime, with a fine and as much as 3 years in prison (49 U.S.C. 32709). Someone who breaks the law to defraud a buyer is liable for triple that buyer's actual damages, with $10,000 as the floor (49 U.S.C. 32710).

None of that touches a seller who tells the truth. Marking the mileage as unknown is the legal way out, not an admission of anything.

The mileage step in each state

Here's what each state's own title page or statute says the seller does with the mileage. "None found" means the state rows we checked didn't address the odometer; the federal rule still applies there.

When the title already carries a mileage brand

If you bought the car with a mileage warning on the title, you're passing that history along, not creating it. Some states list a mileage problem among their title brands: Colorado has "Odometer tampered with" (Colorado DMV), Connecticut has "WARNING: ODOMETER DISCREPANCY" (Conn. Regs. 14-174-3), and Washington has "Odometer not actual" (WAC 308-56A-530).

Fill in the current reading, check the box that matches what you know today, and mention the brand to the buyer up front.

Fix the odometer or sell it as it is

A repair is worth weighing if nothing else is badly wrong and you mean to keep driving it. Remember the door-frame notice if the mileage changes during the repair. A working odometer won't turn an unknown-mileage history back into a known one, though.

Passing it on unrepaired is usually smarter when:

• the car doesn't run, so the mileage matters less than the parts
• the title already says not actual mileage
• the repair bill tops what the car means to you in dollars
• the odometer is only one of several faults

If the miles are high but real, the old or high-mileage car guide is the better fit.

Selling it to us

We buy whole non-running and junk cars, and a broken odometer or a mileage brand doesn't stop that. You can sell the whole car as it sits, with free pickup anywhere in the US.

Before pickup, it helps to know:

• what the odometer shows, and whether it works
• whether the title says not actual or exceeds mechanical limits
• whether the cluster was ever replaced
• the year, make, model and what else is wrong

At pickup, the odometer section still gets filled in honestly, like any other sale. Any buyer purchasing to resell can't accept an incomplete disclosure, so every line needs an answer.
