How Lemon Laws Work in the United States: A Plain-English Guide

A lemon is a vehicle with a warranty defect that the manufacturer can't fix after a reasonable number of tries. The defect has to be serious, too. Most state laws say it must substantially impair the vehicle's use, value or safety. When both things are true, the law can require the manufacturer to buy the vehicle back or replace it.

That's the short version. The longer version depends on your state, your warranty and your repair records. This guide covers how lemon laws work across the country, in plain English, and points you to the pages that go deeper. It's general information, not legal advice for your situation.

What makes a vehicle a lemon?

A vehicle is usually a lemon when three things line up: a defect covered by the warranty, a defect serious enough to matter, and repairs that didn't work.

A covered defect. The problem has to fall under the manufacturer's warranty. Read the warranty booklet to see what it covers and for how long.

It substantially impairs use, value or safety. A rattle in the glovebox probably doesn't qualify. A stalling engine does. Florida's law uses this exact test and excludes problems caused by an accident, abuse, neglect or changes made by anyone other than the manufacturer or its authorized service agent (Fla. Stat. § 681.102).

A reasonable number of repair attempts. The manufacturer gets a fair chance to fix it. Most states define "fair chance" with a presumption, covered below.

State lemon laws vs. the federal Magnuson-Moss Warranty Act

You may have two sets of rights at once: your state's lemon law and the federal Magnuson-Moss Warranty Act. They do different jobs, and one doesn't cancel the other.

State lemon laws are written for motor vehicles. They set the repair tests, the protection period, the notice rules and the buyback formula. Each state writes its own, which is why the numbers change when you cross a state line.

The Magnuson-Moss Warranty Act (15 U.S.C. §§ 2301-2312) is a federal warranty law that covers consumer products in general, including cars and trucks. It lets a consumer sue when a warrantor fails to honor a written warranty, an implied warranty or a service contract (§ 2310(d)(1)). It also says nothing in the Act restricts your rights under state law (§ 2311(b)(1)).

Here's how they compare:

One detail matters a lot under federal law: the label on your warranty. A warranty that meets the federal minimum standards must be called a "full" warranty. Otherwise it must be called "limited" (§ 2303(a)). The rule that lets you choose a refund or replacement after a reasonable number of attempts, § 2304(a)(4), is one of those minimum standards. Under a limited warranty, you can still sue for breach of the written warranty and ask for damages and other relief (§ 2310(d)(1)). Our Magnuson-Moss guide covers the federal side in more detail.

What do state lemon laws usually cover?

Most state lemon laws cover new passenger vehicles bought or leased for personal, family or household use. Coverage beyond that varies a lot.

Florida is a good example of how specific the lines get. Its law covers new vehicles sold in the state, including recreational vehicles, demonstrators and leased vehicles in some cases. It excludes motorcycles, mopeds, off-road vehicles, trucks over 10,000 pounds gross vehicle weight, and the living quarters of an RV (Fla. Stat. § 681.102). Another state may draw every one of those lines differently.

Common questions about coverage:

• Leased vehicles. Many states include leases. See our leased vehicles page.
• Used vehicles. Usually not covered by the state lemon law itself, though federal warranty law may help. See used cars.
• RVs, motorcycles and EVs. Rules differ by vehicle type. See RVs and motor homes, motorcycles and electric vehicles.
• Business use. Coverage for vehicles used in a business varies by state. Check your state's page.

The presumption tests: how many repairs is "reasonable"?

Most state laws presume the manufacturer had a reasonable number of attempts once you meet one of a few tests during a set protection period. Meeting a test doesn't win the case on its own. It shifts the starting point in your favor, and the manufacturer can still raise defenses, such as abuse, neglect or unauthorized changes (Ohio Rev. Code § 1345.75(D); Fla. Stat. § 681.104(4)).

The tests usually come in three flavors:

1. Repeated repairs for the same defect. The same problem was repaired a set number of times and is still there.
2. A serious safety defect. Fewer attempts are needed when the defect could cause death or serious injury.
3. Days out of service. The vehicle spent a total number of days in the shop for warranty repairs. The days usually don't have to be in a row.

Ohio and Florida show how different the numbers can be:

Your state may use different numbers, a different window or extra rules. Our repair attempts page explains what counts as an attempt, how "same defect" is judged and what to do about "no problem found" visits.

Notice and the final repair opportunity

Many states require you to tell the manufacturer in writing about the defect and give it one last chance to fix the vehicle. Telling the service advisor at the dealership usually isn't enough.

Florida spells this out. After three repairs of the same defect, the consumer must send written notice to the manufacturer by registered or express mail. The manufacturer then has 10 days from receipt to respond and offer a repair at a reasonably accessible facility, and 10 days (45 for an RV) after the vehicle arrives to fix it (Fla. Stat. § 681.104(1)(a)).

Federal law has a similar idea. Before most Magnuson-Moss lawsuits, the warrantor must be given a reasonable opportunity to cure the problem (15 U.S.C. § 2310(e)).

Our notice to manufacturer page covers what to put in the letter, how to send it and how to prove it arrived.

Informal dispute programs and arbitration

Some manufacturers run informal dispute programs, often called arbitration. Whether you must use one first depends on your warranty and your state.

Under federal law, a manufacturer can require you to try its program before filing a Magnuson-Moss lawsuit, but only if the program meets the FTC's rules and the requirement appears in the written warranty (15 U.S.C. § 2310(a)(3)). Those rules, in 16 C.F.R. Part 703, say the program:

• can't charge consumers a fee to use it (§ 703.3(a));
• must decide within 40 days of being told about the dispute, with narrow exceptions (§ 703.5(d));
• issues decisions that aren't legally binding on you, though the decision can be used as evidence in a later lawsuit (§ 703.5(j)).

States add their own layer. Florida, for example, requires you to use a manufacturer program first if the state has certified it (Fla. Stat. § 681.108). Our arbitration and dispute programs page explains the trade-offs.

Remedies: buyback, replacement and the use offset

The usual lemon law remedies are a repurchase (often called a buyback) or a comparable replacement vehicle. Many cases also end in a negotiated settlement instead.

Repurchase. The manufacturer takes the vehicle back and refunds what you paid, usually including taxes and fees, and pays off the loan. Ohio's law, for example, requires a refund of the full purchase price plus incidental damages such as lender fees, towing, rental cars, meals and lodging caused by the defect (Ohio Rev. Code § 1345.72(B)).

Replacement. You get a new, comparable vehicle. In Florida, the consumer has an unconditional right to choose a refund instead of a replacement (Fla. Stat. § 681.104(2)(a)).

The reasonable use offset. Many states let the manufacturer subtract a charge for the miles you drove. Formulas differ. Florida multiplies the miles attributable to the consumer by the vehicle's base price and divides by 120,000 (60,000 for an RV) (Fla. Stat. § 681.102).

Federal law defines the same ideas in general terms. A "refund" is the actual purchase price, less reasonable depreciation based on actual use where FTC rules allow, and a "replacement" is an identical or reasonably equivalent product (15 U.S.C. § 2301(11)-(12)). See buyback and replacement for how each piece is calculated and what happens to the vehicle's title afterward.

Attorney's fees

Many lemon laws, and the federal Magnuson-Moss Warranty Act, let a consumer who wins recover reasonable attorney's fees from the manufacturer. We explain exactly how fees work in your case before you sign anything. Our page on attorney's fees and costs covers how this works.

Deadlines you can't ignore

Every lemon law claim runs on a clock, and missing a deadline can end a claim that was otherwise strong. There are usually several clocks, not one.

• The protection period. The window when repair attempts count toward the presumption, such as Ohio's 1 year or 18,000 miles.
• Notice and arbitration deadlines. Florida, for example, requires a request for its state arbitration board no later than 60 days after the rights period ends, or 30 days after a manufacturer program's final action, whichever is later (Fla. Stat. § 681.109(4)).
• The filing deadline. Ohio allows five years from original delivery (Ohio Rev. Code § 1345.75(C)). Florida allows one year after the rights period ends, or one year after a dispute program's final action (Fla. Stat. § 681.112(2)).

The Magnuson-Moss Act has no limitations period of its own. Courts borrow the most closely analogous state period instead. The Illinois Supreme Court, for example, used the four-year period in the Uniform Commercial Code and held that a claim under a repair warranty accrues when the warranty repairs are refused or don't work (Mydlach v. DaimlerChrysler Corp., 2007). Other courts have approached the question differently. Our deadlines page explains each type.

What to do first if you think you have a lemon

Start with your paperwork. A lemon law claim is mostly built on documents, and the most useful ones are easy to lose.

1. Get a repair order every visit. Make sure it shows the date in and out, the mileage, your complaint in your own words and what the technician did. Our guide on documenting repair visits has a checklist.
2. Keep your purchase or lease papers and warranty booklet. The booklet tells you whether there's a dispute program and where to send notice.
3. Keep up with maintenance and save receipts. A manufacturer can deny a warranty remedy for damage caused by unreasonable use, including failing to do reasonable and necessary maintenance (15 U.S.C. § 2304(c)).
4. Look up your state's rules. Find your state on our state lemon laws page, or go straight to a state page such as Ohio or Florida.
5. Send written notice when your state requires it. See notice to manufacturer.
6. Watch the calendar. Write down the delivery date and the end of your warranty and protection period.
7. Talk to a lawyer before you sign anything from the manufacturer, including a goodwill offer or release.
