Dealer lied about a used car in New Mexico: what to do
Checked against official sources: Oct 24, 2026
In New Mexico:
- Deadline to sue for fraud
- 4 years
- Deadline to sue over a written contract
- 6 years
- Do this now
- Collect your Buyers Guide, sales contract, any ads or texts describing the car, and the title and odometer statement.
Dealers who sell used cars must display the FTC Buyers Guide, which says whether the car comes with a warranty or 'as is', and it becomes part of your contract. Even an 'as is' sale does not allow a dealer to lie about the car's condition, title or mileage; federal odometer law and state consumer protection laws give you options.
More about this
There is generally no automatic right to return a car, so act on proof, in writing, and watch your deadline.

Your plan for New Mexico
Do now
Collect your Buyers Guide, sales contract, any ads or texts describing the car, and the title and odometer statement.
Why: Your claim depends on what the dealer said and wrote; the Buyers Guide is part of your contract.
Get an independent mechanic's written inspection describing the problem and, if possible, whether it existed before you bought the car.
Why: A neutral written report is strong proof.
Check the car's title and history with the National Motor Vehicle Title Information System (NMVTIS) through an approved provider.
Why: It can show salvage, flood or junk brands and odometer readings.
Compare the mileage on your odometer statement with earlier records (service records, inspection reports, title history).
Why: Federal law requires a written mileage disclosure when ownership of most vehicles is transferred (some older vehicles are exempt).
Nothing extra here for your answers.
This week
Write to the dealer (template below): say what was misrepresented, attach your proof, and say what you want (repair, refund, or cancel the deal).
Why: A written demand gives the dealer a chance to fix it and creates a record.
If the Buyers Guide shows a dealer warranty, ask for the repair under that warranty in writing.
Why: The Buyers Guide terms override contrary terms in the sales contract.
If you financed, tell the lender in writing about the dispute, and keep making payments while it is resolved. If the lender does not handle your dispute properly, you can complain to the CFPB.
Why: Stopping payments can lead to repossession and credit damage.
Check your state's used-car rules (link below): some states require dealer warranties or limit 'as is' sales.
Why: Your state may give you more protection than federal law.
Compare what you were promised about the warranty or price with the Buyers Guide and the sales contract, and save any ads, texts or emails that show the promise.
Why: Written promises are much easier to prove than spoken ones, and the Buyers Guide is part of your contract.
Nothing extra here for your answers.
If it's not resolved
File a complaint with your state attorney general or consumer protection office, and with the state dealer licensing agency if your state has one.
Why: These offices handle dealer complaints and can act against licensed dealers.
Report the dealer to the FTC.
Why: The FTC enforces the Used Car Rule (Buyers Guide).
For odometer fraud, you can sue under federal law within 2 years; a dealer who acted with intent to defraud owes 3 times your actual damages or $10,000, whichever is greater, plus attorney fees.
Why: This federal law makes odometer cases worthwhile even when the dollar loss is small.
For smaller losses, you can sue in small claims court up to your state's limit. Watch your state's deadlines for fraud and contract claims.
Why: Small claims is designed for people without lawyers.
