Does Washington State Lemon Law Cover Used Cars?

Washington’s Lemon Law does cover used cars, but only a narrow slice of them: the vehicle has to still be inside the original manufacturer’s warranty, and a qualifying repair attempt has to happen before it turns two years old or crosses 24,000 miles, whichever comes first.¹ You don’t have to be the original buyer. A one-year-old certified pre-owned car with 12,000 miles and active factory coverage is in the window. A four-year-old sedan with 60,000 miles and an expired warranty is not.

The Two-Year, 24,000-Mile Window

The eligibility period runs from the day the vehicle was first delivered to its original retail buyer, not from the day you bought it used. For the Lemon Law to apply, at least one repair attempt for the defect has to occur both within two years of that original delivery date and before the odometer passes 24,000 miles.¹ Hit either limit and the window closes, no matter how much room is left on the other measure.

At least one of those repair attempts also has to happen while the manufacturer’s written warranty is still in effect.² The factory warranty is what matters here. A dealer-sold extended warranty or an aftermarket service contract does not extend Lemon Law coverage. If the original three-year, 36,000-mile warranty is still live and the car is only eight months and 10,000 miles into its life, you’re inside the law. If the factory warranty lapsed last month, you aren’t, even if you just drove the car off the lot.

Coverage also reaches more than just cars. The law applies to self-propelled vehicles designed primarily for use on public roads, including trucks, SUVs, motorcycles, motor homes, and demonstrator vehicles.³ Active-duty military stationed or living in Washington can bring a qualifying claim on a vehicle purchased in another state, as long as it came with a manufacturer warranty and was bought within the past 30 months.¹

The 30-Month Deadline for Second and Third Owners

Used-car buyers face a hard outer deadline that trips up a lot of claims. Your Request for Arbitration has to reach the Attorney General’s office within 30 months of the vehicle’s original retail delivery date.¹ That clock runs from when the first owner took delivery, not from when you bought the car. If you buy a 20-month-old vehicle with lingering warranty problems, you have about ten months to work through the manufacturer and still get your form filed. If you’re approaching month 29 and the manufacturer is still stringing you along, file anyway.

What Counts as a Lemon

Being inside the window is just the entry ticket. The vehicle also has to have a “nonconformity” that substantially impairs its use, value, or safety, and the manufacturer has to have had a reasonable number of unsuccessful chances to fix it. Problems caused by owner neglect or unauthorized modifications don’t qualify. The statute sets different thresholds depending on the type of defect:

A serious safety defect — a life-threatening malfunction that impairs your ability to control the vehicle or creates a risk of fire or explosion — qualifies after two unsuccessful repair attempts.²
Two different serious safety defects within a single 12-month period, each repaired at least once during the warranty, can also qualify the vehicle.³
Other substantial defects that aren’t safety-related give the manufacturer four attempts on the same problem.²
If the vehicle has been out of service for a cumulative 30 or more calendar days for diagnosis or repair, with at least 15 of those days falling inside the warranty, it qualifies regardless of how many separate shop visits were involved.²

For every one of these thresholds, at least one repair attempt must have taken place during the manufacturer’s warranty, and the attempt has to be at a service facility the manufacturer has authorized for warranty work.

Replacement or Refund, and How the Mileage Offset Works for Used Buyers

If the vehicle qualifies, you choose between a replacement and a repurchase. The manufacturer doesn’t.³

A replacement means a vehicle identical or reasonably equivalent to yours as it existed at original purchase, including factory and dealer-installed options, undercoating, and service contracts. The manufacturer also covers sales tax, registration, and license fees on the replacement. A repurchase refunds the purchase price plus collateral charges and incidental costs, minus a mileage offset. On a lease, the refund covers all lease payments, any trade-in value or inception payment, your security deposit, and collateral charges; the manufacturer clears the title with the lessor or lienholder and releases you from future lease obligations.

The mileage offset is the number used-car buyers should pay closest attention to. The formula is: miles driven before the first repair attempt for the qualifying defect, multiplied by the purchase price, divided by 120,000.³ The divisor is 25,000 for motorcycles and 90,000 for motor homes. On a $30,000 car driven 5,000 trouble-free miles before the first repair attempt, the offset is $1,250, and the refund is $28,750 plus collateral and incidental costs. Only the miles before that first attempt count; miles racked up during the back-and-forth with the shop don’t inflate the offset.

Here’s the twist that matters for subsequent owners. If you choose a repurchase, the offset is calculated from the date you bought or leased the vehicle, not from the original delivery date.³ If you choose a replacement, the offset covers the full mileage from the original purchase. For most used-car buyers, repurchase produces the smaller deduction.

How to File

Before arbitration, the manufacturer gets one final written chance. Send a letter directly to the manufacturer’s corporate, dispute resolution, zone, or regional office — not the dealer — asking for a repurchase or replacement. Include the make, model, year, and VIN, a description of the defect, and the names and dates of the dealerships where repairs were attempted.⁴ Use certified mail with a return receipt, keep copies of everything, and if you’re close to the 30-month deadline, pay for overnight delivery.

The manufacturer then has 40 days to respond or resolve the problem. If the response doesn’t satisfy you, or none comes, request arbitration through the Attorney General’s Lemon Law Administration.⁴ The Request for Arbitration form is on the Attorney General’s website, or you can call 1-800-541-8898 or email lemon@atg.wa.gov. There is no fee to arbitrate.¹ An impartial arbitrator reviews your evidence and the manufacturer’s response and decides whether the vehicle qualifies.

Your case lives on paperwork. Gather every repair order from the dealership or authorized facility (dates, mileage, reported problem, work performed), your purchase agreement, title and registration, the original manufacturer’s warranty booklet, and copies of all correspondence with the dealer and the manufacturer. Check that the odometer disclosure on your title matches the mileage shown on your repair orders. Federal law requires sellers to provide a written odometer disclosure certifying whether the reading reflects actual mileage,⁵ and a mismatch complicates your timeline.

If Your Used Car Falls Outside the Lemon Law

If the factory warranty has run out, or the two-year or 24,000-mile line is already behind you, the Lemon Law won’t help. Other protections still cover used-car purchases from dealers.

Implied Warranty of Merchantability

Washington law reads an implied warranty of merchantability into every sale by a merchant: the vehicle has to be fit for ordinary driving and of reasonable quality for its price range.⁶ It applies to dealers, not private sellers. A $5,000 car with 120,000 miles doesn’t have to be perfect, but it does have to run and be reasonably safe. Dealers can disclaim this warranty through negotiation and a written statement identifying the parts not covered. But if you buy a service contract from the dealer within 90 days of the sale, the implied warranty of merchantability cannot be waived.⁷

The Magnuson-Moss Warranty Act

If a dealer gives you any written warranty on a used vehicle, or sells you a service contract at the time of sale or within 90 days afterward, the federal Magnuson-Moss Warranty Act bars the dealer from disclaiming implied warranties.⁸ The dealer can match the implied warranty’s duration to the written warranty’s duration, but cannot eliminate it. A 90-day powertrain warranty followed by a transmission failure on day 45 cannot be defeated by an “as-is” clause buried elsewhere in the paperwork.

The FTC Used Car Rule and the Buyers Guide

Federal law requires dealers who sell more than five used vehicles in a 12-month period to post a Buyers Guide on every vehicle before a customer inspects it. The Guide has to disclose whether the car is sold “as is” or with a warranty, and if warranted, what percentage of repair costs the dealer will cover.⁹ The Guide becomes part of the sales contract. If the Guide shows a warranty but the contract says “as is,” the Guide controls. Read what’s on the window before you sign anything.
