South Dakota Lemon Law (2026): How to Qualify & Get a Refund

South Dakota's Motor Vehicle Warranty Law (SDCL 32-6D) covers new vehicles under 15,000 lbs. GVWR used for personal, family, or household purposes, including motorcycles. A vehicle qualifies as a lemon after four repair attempts for the same defect plus one final attempt, or 30 cumulative days out of service, within the rights period.

What Is South Dakota's Lemon Law?

South Dakota's Motor Vehicle Warranty Law, codified in SDCL 32-6D-1 through 32-6D-11, protects consumers who purchase new vehicles that turn out to have serious, unfixable defects. Enacted in 1993, this law gives buyers a path to either a replacement vehicle or a full refund when a manufacturer cannot repair a covered defect within a reasonable number of attempts.

The law applies to vehicles purchased or leased in South Dakota that are used primarily for personal, family, or household purposes. If your new car, truck, SUV, or motorcycle has a recurring problem that the dealer cannot fix, you may have a lemon law claim.

What Vehicles Are Covered

South Dakota's lemon law covers vehicles intended primarily for use on public highways that meet certain criteria. Understanding which vehicles qualify is the first step in determining whether you have a valid claim.

Covered Vehicle Types

• New or previously untitled motor vehicles that are self-propelled and designed for highway use
• Passenger cars and sedans used substantially for personal, family, or household purposes
• Trucks and SUVs under the 15,000 lb. GVWR limit
• Vans and minivans for personal use
• Motorcycles intended for highway use and personal purposes
• Light pickup trucks under the weight threshold
• All-terrain vehicles with four or more wheels and a combustion engine of 200 cubic centimeters or more piston or rotor displacement, which SDCL 32-6D-1 expressly writes into the definition of motor vehicle

Vehicles NOT Covered

• Motor homes (the law specifically excludes them under SDCL 32-6D-1)
• Motor vehicles with a manufacturer's gross vehicle weight rating of 15,000 pounds or more
• Vehicles purchased for the purpose of resale
• Vehicles not used substantially for personal, family, or household purposes
• Electric bicycles as defined in SDCL 32-20B-9
• Multi-passenger quadricycles as defined in SDCL 32-14-17

Key Definitions

Consumer: The purchaser, other than for purposes of resale, of a new or previously untitled motor vehicle used in substantial part for personal, family, or household purposes. The consumer must be entitled by the terms of the warranty to enforce its obligations.

Lemon Law Rights Period: The period ending one year after the date of original delivery to a consumer or the first 12,000 miles of operation, whichever occurs first. You must first report the defect during this window for the lemon law to apply.

Nonconforming Condition: A defect or condition that does not conform to the terms of the manufacturer's express warranty, significantly impairs the use, value, or safety of the motor vehicle, and arises solely in the course of ordinary use.

South Dakota's Lemon Law Presumption

Under SDCL 32-6D-5, South Dakota law creates a rebuttable presumption that the manufacturer has had reasonable attempts to correct a nonconforming condition when certain thresholds are met. This presumption shifts the burden of proof in favor of the consumer.

When the Presumption Applies

The presumption applies when either of the following conditions is met within 24 months of delivery or 24,000 miles, whichever occurs first:

Important: The 30-day out-of-service calculation does not include time when repair could not be performed because of conditions beyond the control of the manufacturer or its dealers. Examples include war, invasion, strike, fire, flood, or other natural disaster.

What Qualifies as a Nonconforming Condition?

South Dakota defines a nonconforming condition as one that meets all three of these criteria:

• It does not conform to the terms of any express warranty issued by the manufacturer
• It significantly impairs the use, value, or safety of the motor vehicle
• It occurs or arises solely in the course of ordinary use of the motor vehicle

The nonconformity must NOT arise from:

• Abuse, neglect, or modification not authorized by the manufacturer
• Any accident or other damage occurring after dealer delivery to the consumer

Minor cosmetic issues, normal wear items, and problems caused by aftermarket parts generally do not qualify as nonconforming conditions under the statute.

Consumer Remedies: Refund vs. Replacement

When a vehicle qualifies as a lemon under South Dakota law, the consumer has the right to choose between a replacement vehicle or a full refund. The manufacturer cannot force one option over the other.

Option 1: Replacement Vehicle

Under SDCL 32-6D-3, the manufacturer must provide:

• A comparable new motor vehicle of the same make and model (or a reasonably equivalent vehicle)
• Refund of all collateral charges, including excise tax, license, registration fees, and similar government charges

Option 2: Full Refund

If the consumer chooses a refund, the manufacturer must return:

• Full contract price: Including undercoating, dealer preparation, and transportation charges
• Installed options: Cost of all options installed at the time of purchase
• Extended warranties and service contracts: Nonrefundable portions of any extended warranty or service contract
• Collateral charges: Excise tax, license, registration fees, and similar government charges
• Finance charges: All finance charges incurred after the consumer first reported the nonconformity to the manufacturer or dealer
• Incidental damages: Reasonable cost of alternative transportation during the period the consumer was without the vehicle due to the nonconforming condition

Usage Deduction Formula

The manufacturer may offset the refund by a reasonable allowance for the consumer's use of the vehicle before the first report of the defect. Under SDCL 32-6D-4, South Dakota calculates this as:

Usage Deduction = (Full Purchase Price x Miles Before First Report) / 100,000

For example, if you purchased a vehicle for $40,000 and drove 5,000 miles before reporting the first defect, the usage deduction would be $2,000.

South Dakota uses 100,000 miles as the denominator in this formula. Compared to states that use a 120,000-mile denominator, South Dakota's formula results in a higher deduction per mile driven, so the faster you report the defect, the smaller the deduction.

Refunds are made to the consumer and any lienholders, as their interests may appear. If there is a loan on the vehicle, the lender will receive the remaining balance and the consumer receives the rest.

How to File a Lemon Law Claim in South Dakota

Filing a successful lemon law claim in South Dakota requires careful documentation and strict adherence to notice and procedural requirements. Missing a step can delay or derail your claim.

Step 1: Document Everything From Day One

Thorough documentation is the foundation of a strong lemon law claim. Keep the following records:

• All repair orders, work orders, and invoices from every dealer visit
• Dates your vehicle was dropped off and picked up from the shop
• Written descriptions of the symptoms you experienced each time
• All correspondence with the dealer and manufacturer, including emails and letters
• Photos or videos of the defect, warning lights, or safety issues when possible
• A log of how the defect affects your daily use of the vehicle

Tip: Request a repair order every time you bring your vehicle in for service. If a visit is not documented on a repair order, it may not count toward the four-attempt threshold required under the lemon law.

Step 2: Report the Nonconformity

Deliver the motor vehicle to the manufacturer or its authorized dealer and give notice of the nonconforming condition during the lemon law rights period (1 year or 12,000 miles, whichever comes first). Verbal notice to the dealer is sufficient for this step, but written notice creates a stronger record.

Step 3: Allow Repair Attempts

Give the manufacturer or authorized dealer a reasonable opportunity to repair the nonconformity. The manufacturer's obligation to repair extends up to 24 months or 24,000 miles from delivery, whichever occurs first, as long as the initial notice was given during the lemon law rights period.

Step 4: Send Written Notice for Final Repair Opportunity

Before filing a lawsuit, you must give the manufacturer written notice by certified mail demanding correction of the defect. This triggers the final repair opportunity process outlined in SDCL 32-6D-6.

Step 5: Exhaust Informal Dispute Settlement Procedure (If Applicable)

SDCL 32-6D-6 requires exhaustion only where the manufacturer has established an informal dispute settlement procedure "conducted within the state" that is in compliance with federal rules and regulations. If such an in-state program exists, you must exhaust it before bringing a state lemon law action. A national arbitration program that is not conducted within South Dakota does not trigger this state-law requirement. A separate federal rule, 15 U.S.C. 2310(a), can still require you to use a qualifying mechanism that the manufacturer incorporated into the written warranty before you sue under the Magnuson-Moss Warranty Act. Not all manufacturers maintain these programs, so check with the manufacturer first.

Final Repair Opportunity

South Dakota's lemon law includes a "final repair opportunity" provision that gives manufacturers one last chance to fix the vehicle before legal action can proceed. This step is mandatory and cannot be skipped.

Notice Requirements

Under SDCL 32-6D-6, consumers must send a "notice of nonconforming condition" by certified mail. This written statement must include:

• A description of the motor vehicle (year, make, model, VIN)
• A description of the nonconforming condition
• All previous attempts to correct the condition, identifying who made each attempt and when

Manufacturer's Response Timeline

Within seven calendar days of receiving the certified mail notice, the manufacturer must notify the consumer of a reasonably accessible repair facility where the final attempt will be made.

Final Repair Period

After the consumer delivers the vehicle to the designated repair facility, the manufacturer has fourteen calendar days to attempt to correct the nonconforming condition and bring the vehicle into conformity with the express warranty.

If the Final Repair Fails

If the manufacturer is unable to repair the vehicle within the 14-day final repair period, the consumer may bring a civil action against the manufacturer to enforce the lemon law. At this point, the presumption under SDCL 32-6D-5 works in the consumer's favor.

Attorney Fees and Legal Costs

Under SDCL 32-6D-8, if the manufacturer has breached its obligations under the lemon law, the consumer may recover reasonable attorney fees in addition to the refund or replacement remedy. This provision is significant because it makes it financially feasible for consumers to hire a lawyer to pursue their claim.

Many lemon law attorneys in South Dakota work on a contingency basis, meaning the consumer pays nothing upfront. If the case is successful, the manufacturer typically pays the attorney fees as part of the judgment or settlement.

Manufacturer Defenses

Under SDCL 32-6D-7, manufacturers have specific affirmative defenses available when a consumer files a lemon law claim.

The burden of proving these defenses rests with the manufacturer. Consumers who keep thorough maintenance records and follow the owner's manual recommendations are in the strongest position to defeat these defenses.

Resale of Returned Lemon Vehicles

South Dakota has specific requirements for vehicles returned under the lemon law. These rules protect subsequent purchasers from unknowingly buying a vehicle with a history of serious defects.

Requirements for Reselling Lemon Buybacks

Under SDCL 32-6D-9, if a motor vehicle has been returned under the lemon law (whether through a court judgment or informal dispute settlement), it may not be resold in South Dakota unless both of these conditions are met:

• Written disclosure: The manufacturer must disclose in writing to the subsequent purchaser that the vehicle was returned under the lemon law and describe the nature of the nonconformity
• Title branding: The manufacturer must return the title to the South Dakota Department of Revenue, advising that the vehicle was returned under the lemon law. The department then brands the title with the statement: "This vehicle was returned to the manufacturer because it did not conform to its warranty."

This title branding follows the vehicle permanently and appears on all subsequent titles issued for that vehicle, regardless of how many times it changes hands.

Dealer Protection

South Dakota's lemon law includes strong protections for motor vehicle dealers, recognizing that manufacturing defects are the manufacturer's responsibility, not the dealer's.

Under SDCL 32-6D-10:

• Nothing in the lemon law imposes any liability upon a motor vehicle dealer or authorized dealer
• No cause of action is created against dealers by the lemon law
• Manufacturers may NOT charge back or require reimbursement from dealers for any costs arising out of the lemon law, including refunds or vehicle replacements

This means your lemon law claim is directed at the manufacturer, not the dealership where you purchased the vehicle.

Statute of Limitations

Under SDCL 32-6D-11, any action brought under South Dakota's lemon law against the manufacturer must be commenced within three years following the date of original delivery of the motor vehicle to the consumer.

If you miss this three-year deadline, you lose the right to file a lemon law claim under state law. You may still have a breach of warranty claim under the federal Magnuson-Moss Warranty Act, but that act contains no limitations period of its own. Courts borrow the forum state's Uniform Commercial Code deadline, which in South Dakota is the four years set by SDCL 57A-2-725. That section provides that a breach of warranty occurs when tender of delivery is made, so the four years generally run from the date the vehicle was delivered to you, not from a later failed repair. The exception is a warranty that explicitly extends to future performance of the vehicle, in which case the claim accrues when the breach is or should have been discovered.

Federal Warranty Protection: Magnuson-Moss Act

If your vehicle does not qualify under South Dakota's state lemon law, you may still have rights under the federal Magnuson-Moss Warranty Act, 15 U.S.C. 2301 to 2312. The provision that actually creates the consumer's remedy is 15 U.S.C. 2310, titled "Remedies in consumer disputes." This federal backstop covers:

• Both new and used vehicles still under a manufacturer's warranty
• Vehicles that may exceed the state lemon law's weight or mileage limits
• Situations where South Dakota's three-year lemon law deadline has passed but the borrowed four-year UCC period under SDCL 57A-2-725 has not run

Under 15 U.S.C. 2310(d), a consumer damaged by a warrantor's failure to comply with a written warranty may sue for damages and other legal and equitable relief in state or federal court, and a consumer who finally prevails may be awarded costs and expenses, including attorney fees based on actual time expended. That fee-shifting provision is what makes the federal route practical for an ordinary buyer. Under 15 U.S.C. 2310(a), if the warrantor incorporated a qualifying informal dispute settlement mechanism into the written warranty, the consumer must first resort to that mechanism before filing suit.

The Magnuson-Moss Act sets no filing deadline of its own. Courts apply the forum state's UCC limitations period, which in South Dakota is the four years in SDCL 57A-2-725, running from tender of delivery unless the warranty explicitly extends to future performance.

Tips for Strengthening Your Claim

Follow these practical steps to build the strongest possible lemon law case:

• Always go to an authorized dealer for warranty repairs, not an independent shop
• Request a written repair order for every visit, even if the dealer says the problem could not be replicated
• Describe the same problem consistently on each repair order so there is a clear pattern
• Keep a personal log of dates, mileage, and symptoms between dealer visits
• Send all formal notices by certified mail with return receipt requested
• Do not make unauthorized modifications to the vehicle while pursuing a claim
• File your claim promptly and do not wait until close to the three-year deadline

Frequently Asked Questions

How many repair attempts does South Dakota require before a vehicle is considered a lemon?

South Dakota requires four or more repair attempts for the same nonconforming condition, plus one final attempt by the manufacturer after written certified mail notice. At least one of these repair attempts must occur during the lemon law rights period (1 year or 12,000 miles). Alternatively, if the vehicle is out of service for 30 or more cumulative calendar days due to repair attempts, it may qualify.

What is the final repair opportunity in South Dakota?

Before filing a lawsuit, consumers must send written notice by certified mail to the manufacturer demanding correction of the defect. The manufacturer then has 7 calendar days to designate a repair facility and 14 calendar days after the vehicle is delivered to attempt final repairs. This step is required even after the standard repair attempts have been exhausted.

Does South Dakota's lemon law cover used vehicles?

No. South Dakota's lemon law covers only new or previously untitled motor vehicles. This may include demonstrator vehicles or executive vehicles that have never been titled to a consumer. Previously titled used vehicles are not covered under the state lemon law, though the federal Magnuson-Moss Warranty Act may provide protection for used vehicles still under a manufacturer warranty.

Does South Dakota's lemon law cover motorcycles?

Yes. South Dakota's lemon law covers motorcycles that are intended primarily for use and operation on the public highway, are under 15,000 lbs. GVWR, and are used substantially for personal, family, or household purposes. A machine that is not intended primarily for highway use, such as a dirt bike, falls outside that definition. Note that SDCL 32-6D-1 also expressly covers all-terrain vehicles with four or more wheels and an engine of 200 cubic centimeters or more, so a qualifying ATV is covered even though it is not a highway vehicle. The statute's only named exclusions are electric bicycles, multi-passenger quadricycles, motor homes, and vehicles rated at 15,000 pounds GVWR or more.

What is the usage deduction in South Dakota and how is it calculated?

The manufacturer may deduct a reasonable allowance for miles driven before you first reported the nonconformity. The formula under SDCL 32-6D-4 is: (Full Purchase Price x Miles Before First Report) / 100,000. For example, on a $40,000 vehicle with 5,000 miles at first report, the deduction would be $2,000. Report the defect as early as possible to minimize this deduction.

Can I recover attorney fees if I win my lemon law case in South Dakota?

Yes. Under SDCL 32-6D-8, if the manufacturer has breached its obligations under the lemon law, the consumer may recover reasonable attorney fees in addition to the refund or replacement remedy. Many South Dakota lemon law attorneys work on contingency, meaning the consumer pays nothing upfront.

Do I have to use a manufacturer's arbitration program before suing?

For a state lemon law suit, only if the manufacturer has established an informal dispute settlement procedure conducted within South Dakota that complies with federal rules and regulations. SDCL 32-6D-6 limits the exhaustion requirement to an in-state procedure, so a program run outside South Dakota does not trigger it. A separate federal rule, 15 U.S.C. 2310(a), can still require you to use a qualifying mechanism incorporated into the written warranty before suing under the Magnuson-Moss Warranty Act. Not all manufacturers maintain these programs, so check with your manufacturer first.
