Lemon Law Limits on Used Cars: What Is Covered

Most state lemon laws protect new-car buyers, and only a few states extend similar rights to used cars, usually with tight limits on age, mileage, price or the dealer warranty period. If your used car is a lemon, the claim often runs through the remaining factory warranty, a dealer warranty or federal warranty law instead. The federal Magnuson-Moss Act, at 15 U.S.C. 2310, lets buyers sue when a written or implied warranty is broken. Check your state rule before you assume a lemon law applies.

Why used cars are often left out

State lemon laws are usually tied to the manufacturer's new-car warranty and a set period after delivery. A used car bought after that period, or after the factory warranty ends, often falls outside it. A car still under its original warranty may still qualify in some states if the defect is reported in time.

States with used-car rules

A few states have separate used-car lemon or warranty laws with minimum dealer warranties based on mileage, plus repair-attempt rules. The details differ. Our state guides, such as the California used car lemon law guide, cover how each one works.

Common limits

• Mileage or age caps on which cars qualify.
• A purchase price floor.
• Dealer sales only; private sales are usually excluded.
• A short coverage window after the sale.
• A set number of repair attempts or days out of service.
• Major parts only, such as engine and transmission.

What to use when the lemon law does not apply

A remaining factory warranty, a dealer written warranty or the implied warranty of merchantability may still help. The Buyers Guide required by 16 CFR 455.2 tells you which one you got. Our as-is guide covers what happens when there is none.

Buying a car that was already a lemon

A manufacturer buyback can come back to market. Many states require a lemon brand or a disclosure on the title. Our lemon buyback title brand guide covers how those show up, and a recall check at the NHTSA recall lookup catches open campaigns.

Steps to take if the car keeps failing

Write down every repair visit with the date, the mileage and the complaint, and get a copy of each repair order. Notify the dealer and, if a factory warranty applies, the manufacturer in writing. Keep the car available for repair attempts, since many laws require a chance to fix it. If the defect affects safety, file a report through NHTSA as well. A consumer lawyer in your state can tell you which law fits; many take warranty cases because some statutes shift fees to the seller.

Questions to ask before you buy

• Is any factory warranty left, and does it transfer to me?
• Does the dealer give a written warranty, and for how long?
• Has the car ever been bought back by the maker?
• Can I see the repair orders from earlier owners?

Reading the history report

Read the title section first: any salvage, rebuilt, flood or lemon brand changes the value more than anything else. Then line up the odometer readings by date and look for gaps or drops. Check the number of owners and the states where the car was registered. An approved NMVTIS check adds insurer and salvage-yard records. Our odometer discrepancy guide explains odd mileage entries.

Paperwork to keep

Keep the buyer's order, the retail installment contract, the odometer statement, any Buyers Guide, warranty or service-contract papers and every payoff or lien letter in one folder. Photograph the window sticker and the dash mileage on the day you sign. If a dispute comes up later, dated paperwork is what a lender, an insurer, a dealer licensing agency or a court will ask for first.

Compare the financing

Get a preapproval from a bank or credit union before you visit, so you can compare it with the dealer offer on the same term. Compare the APR, the amount financed and the total interest, not just the monthly payment. The CFPB auto loan tools walk through what to read on an offer. Decide on add-ons such as GAP and service contracts on their own merits, and get the price of each one in writing.

What the report costs

As of early November 2026 a CARFAX bought direct usually costs around $44.99, and AutoCheck sits a little lower. We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Our guest price has been about $5.50 a report, about $4.50 for members, and about $6.75 for a CARFAX and AutoCheck bundle. Confirm the price at checkout, since it can change.
