Mississippi Used Car Lemon Law: Warranty Rules That Still Protect You

Mississippi's lemon law can reach a used car, but only a young one still under the factory warranty, and the repair presumption runs out one year after the car was first delivered. What makes Mississippi different for used-car buyers is its implied warranty law. A dealer generally can't wipe out the implied warranty of merchantability with a plain "as is" line, and the exception for older or high-mileage cars comes with strict paperwork. So the warranty question is often more useful to you here than the lemon law itself.

On Sunday, October 18, 2026, I read the Motor Vehicle Warranty Enforcement Act as posted by the Mississippi Motor Vehicle Commission (a 2019 code edition), the BBB National Programs Mississippi lemon law summary, the Attorney General's consumer protection page and two Mississippi appellate opinions on as-is used car sales. I'm not a lawyer. Statutes get amended, so check the current text before you lean on any number below.

Who counts as a consumer under 63-17-151

The Act defines a consumer as the buyer, other than for resale, of a vehicle used mainly for personal, family or household purposes, and also anyone the car is transferred to for those purposes during the term of an express warranty. That second part is why a used buyer can qualify. It covers demonstrators and lease-purchase cars if a manufacturer's warranty came with the sale, and excludes motorcycles, off-road vehicles and the motor home parts added by the motor home builder.

The presumption is tight. A reasonable number of attempts is presumed if, within the warranty term or one year from original delivery, whichever ends first, the same defect was repaired three or more times and remains, or the car was out of service a total of 15 or more working days. You must notify the manufacturer in writing, and it then gets 10 working days at a repair facility to fix it. A replacement or refund is reduced by 20 cents a mile for your use. Suits must be filed within one year after the warranty term or 18 months after original delivery, whichever is earlier. If the manufacturer runs an informal dispute program that meets 16 CFR 703, you have to use it first.

So if you bought a two-year-old car, the one-year presumption is gone, even if the warranty isn't. You can still have a warranty claim. You just won't get the lemon law's shortcut.

The as-is rule that actually matters

Mississippi Code 75-2-315.1 makes language that tries to exclude the implied warranties of merchantability and fitness on consumer goods unenforceable, and 11-7-18 and 75-2-719(4) back that up, as quoted by the Mississippi Court of Appeals in a 2006 used-car case (No. 2006-CA-01373-COA). The exception, as quoted in those opinions, applies only to a titled vehicle more than six model years old or driven more than 75,000 miles, and only if the seller gives you notice on a form prescribed by the Attorney General. A disclaimer of merchantability has to be written, mention merchantability, be conspicuous, and be separately signed by you. In the earlier case a five-year-old car with under 70,000 miles was sold with an "as is" line, and the court held that line didn't work.

Practically, read every page you sign. If a dealer hands you a separate form about implied warranties on an older car, that's the exception being used. The FTC Buyers Guide required by the Used Car Rule still goes on the window, and our Buyers Guide explainer covers how the boxes read.

Who regulates dealers, and where to complain

The Motor Vehicle Commission says it regulates the sale, distribution and advertising of new vehicles and licenses manufacturers, warrantors, new-vehicle dealers and their salespeople. A used-only lot isn't something its homepage claims. Violations of the lemon law fall under the Consumer Protection Act (Title 75, Chapter 24), and the AG's Consumer Protection Division enforces that law and offers consumer mediators. I found no Mississippi right to return a used car after signing, and the FTC's Cooling-Off Rule exempts car sales at auctions, tent sales or other temporary sites when the seller has a permanent location. Our post on returning a used car goes deeper.

What a report won't settle for you

A history report can show a lemon buyback, salvage or flood brand, but it won't tell you if your dealer used the AG's implied warranty form. Mississippi also sees flood cars after Gulf storms, and a dried-out interior can look fine for months. Read our Mississippi flood title risks, salvage and rebuilt title rules and private sale title transfer guides, and search NMVTIS.
