Minnesota Car Laws

Used Car Warranty Law

Minnesota has one of the strongest used car warranty laws in the country. Under the Minnesota used car warranty law, Minn. Stat. § 325F.662, used car dealers must provide basic warranty coverage for most used cars and small trucks sold to Minnesota buyers. The used car warranty law does not apply, however, if you buy a used car from a relative or friend, from a private party, or if your car falls into one of the used car warranty law’s exclusions (listed below).

The Basic Used Car Warranties

The used car warranty law covers used cars purchased primarily for personal, family, or household purposes. The terms and length of the warranty will depend upon the mileage on the car at the time you buy it. 

The parts covered under the warranty also depend on the mileage of the car at the time you buy it.  For cars with less than 36,000 miles, the parts covered under the warranty include:

For cars with between 36,000 and 200,000 miles, the warranty covers the parts listed above, except for the following parts, which are not covered:

Parts are not covered under the used car warranty law if they are not specifically listed above.

Who Provides a Used Car Warranty?

The used car warranty law applies only if you buy your car from a used car dealer. The law does not apply if you buy a used car from a relative, friend, or neighbor. Nor does the law apply if you buy your car from:

“Unlicensed” Dealers

One problem the used car warranty law addresses is the problem of “unlicensed dealers.” State law says that any person who is in the business of selling used cars and who sells more than five used cars in a year is a “dealer,” and must obtain a dealer’s license. An unlicensed dealer is a person who sells more than five used cars in a year but fails to get a dealer’s license. Typically, an unlicensed dealer sells cars one at a time from the unlicensed dealer’s home or business. If you buy a qualifying car from an unlicensed dealer, then your car is covered by the used car warranty law. In such a case, you are legally entitled to warranty coverage even if the unlicensed dealer fails to give you any written warranty documents.


Remember that the used car you buy might not be covered by the used car warranty law. The following cars are excluded from the law, and although a dealer may still choose to offer a warranty, these cars are usually sold “as is:”

The “Buyers Guide”

A federal rule requires that dealers post a notice called a “Buyers Guide” in the side window of all used cars offered for sale. If a car is covered by the state’s used car warranty law or another warranty, then the dealer must check the “dealer warranty” box on the Buyers Guide. The dealer must also describe the terms and length of the warranty on the Buyers Guide. If a car is not covered by the warranty law and no warranty is offered, then the “as is—no dealer warranty” box must be checked.

Even if the car you buy is covered under the used car warranty law, you may waive warranty coverage for a particular covered part by following a specific procedure. In order for warranty coverage to be waived, the dealer must disclose on the Buyers Guide that the part is not working properly, and you must sign and circle this statement.

A dealer may not, however, avoid providing a warranty required under Minnesota law by failing to disclose the existence of the warranty on the “Buyers Guide” or through separate “as is” agreements or disclaimers.

The Dealer’s Duty Under the Warranty

If a malfunction, defect, or failure in a covered part occurs during the warranty period, then the dealer must repair or replace the part at no charge to the car buyer. However, to protect your rights under the warranty, you must promptly notify the dealer of the problem within the warranty period, and you must arrange to have the vehicle taken to the dealer for inspection and repair.

If the dealer does not have a repair facility, the dealer will tell you where to take the vehicle for inspection and repair under the warranty. If it is impossible or unreasonable to return the vehicle to the dealer, you may have the repairs done somewhere else with the dealer’s consent. If a part is repaired or replaced under the car’s warranty, the warranty for that part is extended from the date of repair for an additional warranty period.

For example, if your car’s transmission is repaired under its used car warranty, then the transmission remains under warranty for an additional 30 days or 1,000 miles (or 60 days or 2,500 miles) from the date of the repair.

The dealer is not responsible for any malfunctions, defects, or failures that occur after the warranty period expires, nor is the dealer responsible for repair of parts not covered by the warranty.


A dealer may decide to refund the purchase price of your car, rather than repair or replace a warranty part. If the dealer gives you a refund, you must return the vehicle to the dealer. The refund must include all the charges, fees, and taxes you paid, including towing expenses, minus a reasonable deduction for your use of the vehicle. The dealer must also provide you with an itemized statement separately listing the amounts refunded for each of these categories.

Remember that the dealer has the choice of correcting the warranty problem or giving you a refund; the law does not give the car buyer the right to demand a refund of the purchase price.

Ordinary Maintenance

A warranty given under the used car warranty law does not cover ordinary maintenance of your car. Thus, repair or replacement of maintenance items (such as spark plugs, ignition points, filters, fluids, lubricants and oil, and brake pads) is your responsibility. The warranty does not cover normal wear and tear.

Limits on the Warranty

The warranty does not cover any repair problems caused by collisions, abuse, negligence, or lack of adequate maintenance after you buy the car. The dealer is not required to repair any parts still covered by the original factory warranty, or parts that the manufacturer agrees to repair at no charge.

Bringing a Lawsuit

If a used car dealer fails to comply with the warranty law, you may bring a lawsuit against the dealer. Any lawsuit under the used car warranty law must be brought within one year after the warranty expires.

Often, you will be able to bring your case in conciliation court, where the procedures are relatively informal and you will not be required to hire an attorney.

Much of the expense of owning a car comes after you buy it. After three or four years of driving, the muffler may roar, the brakes may grind, the windshield wiper fluid may leak, or the radio may go out. Slowly but surely, your vehicle will begin to show signs of age. As Murphy’s Law says, “anything that can go wrong, will go wrong” just after the warranty has run out!

Know the Difference Between Service Contracts and the Used Car Warranty Law

If you are offered an “extended warranty” at an additional cost, this is probably a service contract, not a warranty. Service contracts provide limited coverage, so you should read the service contract carefully before deciding whether you want to buy this coverage. Furthermore, the service contract may require you to prove that you completed regular maintenance (oil changes, etc.) on the vehicle or obtain pre-approval before a repair is made. You should also be aware that a service contract is frequently a profit item for the dealer; like any other add-on, the cost may be negotiated.
