South Dakota Used Car Lemon Law: What a Used Buyer Can Use

A used car bought in South Dakota isn't protected by the state's lemon law. The statute protects buyers of new or previously untitled vehicles, and the Attorney General's office says flatly that it "pertains to new vehicles only." The AG also says every used vehicle is sold as is unless factory warranty remains or the dealer writes in its own warranty. You also don't get a three-day cancel right on a car bought at a dealer's lot. What you can lean on is any written warranty, the deceptive trade practices law, and the state's lemon buyback title brand, which tells you a car went back to the factory.

I read SDCL chapter 32-6D, the deceptive trade practices sections and the dealer licensing rule on the legislature's site, plus the AG's automotive consumer page and the Department of Revenue's dealer licensing page, on Sunday, October 18, 2026. Not legal advice. If you're near a deadline, call a lawyer.

Who the law covers and for how long

SDCL 32-6D-1 defines a consumer as someone who buys a new or previously untitled motor vehicle, not for resale, and uses it in substantial part for personal, family or household purposes. The "lemon law rights period" ends one year after the original delivery or at 12,000 miles, whichever comes first. The definition of motor vehicle is wider than in many states. It includes four-wheel ATVs with engines of 200 cc or more, but leaves out motor homes, e-bikes and vehicles rated at 15,000 pounds or more. A car that's already been titled to someone else is outside the definition, so a typical used car never qualifies.

How a new-car claim works

• Report the problem to the manufacturer or a dealer during the rights period. Under 32-6D-2, the repair duty continues after the period ends but stops at 24 months or 24,000 miles.
• The car is presumed a lemon if, within 24 months or 24,000 miles, the same defect got four or more repair attempts plus a final attempt, or the car was in the shop 30 or more calendar days, with at least one visit inside the rights period (32-6D-5).
• Before suing, send the manufacturer notice by certified mail. It gets seven calendar days to name a repair shop and 14 days to fix the car, and if it runs a compliant dispute program in the state, you have to use that first (32-6D-6).
• If it can't be fixed, 32-6D-3 lets you choose a replacement or a refund of the full contract price, taxes and fees, finance charges after your first report and incidental costs like a rental, less a mileage-based allowance for use. Sue within three years of delivery.

The AG's page adds practical advice: get a repair order every time, because an undocumented visit can't count toward the presumption.

Used cars: as is, and no cooling-off

The AG's automotive page says a dealer selling as is isn't responsible for repairs after the sale unless it's in writing, and it tells you to get every promise on paper and have a mechanic at another shop inspect the car. South Dakota's UCC, SDCL 57A-2-316, lets "as is" language exclude implied warranties, and the federal Buyers Guide under 16 CFR 455 must say whether a dealer car comes with a warranty. The AG's door-to-door sales page describes a three-day cancel right, but only for purchases made at home or somewhere other than the seller's place of business. A purchase that starts on the lot doesn't qualify.

Lying is a separate matter. SDCL 37-24-6 makes it a deceptive practice to knowingly misrepresent, or conceal or omit a material fact, in a sale, and 37-24-31 lets someone harmed by that sue for actual damages. File a complaint with the AG's Division of Consumer Protection at 1-800-300-1986 (in-state) or through its online form.

What a history report won't tell you here

A report is only as good as the records behind it. It can miss an in-house warranty the dealer promised out loud, a repair paid in cash, or a hail claim that was never filed. The AG's page says to ask for the title to see any damage disclosure, and our South Dakota hail and salvage title post explains why hail matters so much there. A lemon buyback is easier to spot. Under SDCL 32-6D-9, a returned car can't be resold in the state until the manufacturer tells the next buyer in writing and the Department of Revenue brands every later title "This vehicle was returned to the manufacturer because it did not conform to its warranty." Our lemon buyback title brand post covers the national picture.

Dealers need a state license under 32-6B-4, and the Department of Revenue's dealer agents investigate complaints. One mismatch to know about: the AG's page gives 605-773-3541 for odometer tampering reports, while the DOR licensing page lists (605) 882-5192 for its dealer licensing office. Use the DOR number first.
