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 under the original manufacturer’s warranty, and it has to have been purchased before it turned two years old or crossed 24,000 miles on the odometer, whichever came first.¹ You do not have to be the original buyer. A one-year-old certified pre-owned car with 12,000 miles and an active factory warranty fits. A four-year-old sedan with 60,000 miles and no factory coverage left does not.

The Eligibility Window for Used Cars

The clock starts on the day the vehicle was first delivered to its original retail buyer, not the day you bought it. For a defect to count, at least one repair attempt has to happen both within two years of that original delivery date and before the odometer passes 24,000 miles.¹ Once either limit is hit, the window closes regardless of how much room is left on the other.

At least one of those repair attempts also has to occur while the manufacturer’s written warranty is still in effect.² The factory warranty is the one that matters. A dealer-sold extended warranty or an aftermarket service contract does not open the door.

As a second or third owner, you can still request arbitration, but the request has to reach the Attorney General’s office within 30 months of the original retail delivery date.¹ That 30-month cutoff is absolute. If you are close to it and still negotiating with the manufacturer, file the form anyway.

What Counts as a Lemon

A vehicle qualifies when it has a “nonconformity” that substantially impairs its use, value, or safety, and the manufacturer has had a reasonable number of chances to fix it. Minor annoyances, or problems caused by owner neglect or unauthorized modifications, don’t count. The number of chances the manufacturer gets depends on the type of defect.

Serious safety defect: Two unsuccessful repair attempts. This covers life-threatening malfunctions that affect your ability to control the vehicle or create a risk of fire or explosion.²
Other substantial defect: Four attempts on the same problem.²
Days out of service: A combined 30 or more calendar days in the shop for diagnosis or repair, with at least 15 of those days falling inside the warranty period.²

Under all three thresholds, at least one repair attempt has to have taken place while the manufacturer’s warranty was active. A visit counts as a repair attempt when you present the vehicle to a facility the manufacturer has authorized for warranty work.

What You Get: Replacement or Refund

If the vehicle qualifies, the choice between a replacement and a repurchase is yours, not the manufacturer’s.³

A replacement means an identical or reasonably equivalent vehicle in the same condition as your original at the time of purchase, including factory- and dealer-installed options, undercoating, and service contracts. The manufacturer also pays the sales tax, registration, and license fees on the replacement. You owe a mileage offset for the use you got out of the original.

A repurchase means the manufacturer refunds the purchase price plus collateral charges and incidental costs, minus the mileage offset. For a leased vehicle, the refund covers your lease payments, any trade-in value or inception payment, your security deposit, and collateral charges, and the manufacturer clears the title with the lessor or lienholder so you are released from future lease obligations.

The Mileage Offset, and Why It Matters More for Used Buyers

The offset accounts for the trouble-free use you got before the defect surfaced. The formula: miles driven before the first repair attempt for the qualifying defect, multiplied by the purchase price, divided by 120,000.³ On a $30,000 car with 5,000 trouble-free miles before the first repair attempt, the offset is (5,000 × $30,000) ÷ 120,000 = $1,250, leaving a $28,750 refund before collateral and incidental costs. Only the miles before the first repair attempt count. Miles you put on the car while it kept coming back to the shop don’t inflate the deduction.

If you are not the original buyer and you choose a repurchase, the offset is calculated from the date you bought or leased the vehicle, not from the original delivery date. If you choose replacement, the offset covers the full mileage from the original purchase.³ For most used-car buyers, a repurchase produces the smaller offset.

How to File a Lemon Law Claim

Before arbitration, you have to give the manufacturer one last chance. Send a written request to the manufacturer’s corporate, dispute resolution, zone, or regional office asking for a repurchase or replacement. Not the dealer. The letter should include the vehicle’s year, make, model, and VIN, a description of the defect, and the names and dates of every dealership where repairs were attempted.⁴

Send it certified mail, return receipt requested, and keep copies of everything. If the 30-month arbitration deadline is close, use overnight delivery.

The manufacturer has 40 days to respond or resolve the issue. If the response is inadequate or none comes, you request arbitration through the Attorney General’s Lemon Law Administration.⁴ The Request for Arbitration form is on the Attorney General’s website; you can also call 1-800-541-8898 or email lemon@atg.wa.gov. Arbitration costs nothing.¹ An impartial arbitrator reviews the evidence from both sides at a hearing and decides whether the vehicle qualifies.

Documentation to Pull Together

The claim rises or falls on paperwork. Have all of this ready before you start:

Every repair order from the dealership or authorized facility, with dates, mileage at each visit, the problem you reported, and the work performed.
Your purchase agreement, showing purchase date, price, and terms.
Title and registration.
The original manufacturer’s warranty booklet.
Copies of all letters, emails, and call logs with the dealer and the manufacturer.

For a used car, check that the odometer disclosure on your title lines up with the mileage on your repair orders. Federal law requires sellers to provide a written odometer disclosure at the time of sale, certifying whether the reading reflects actual mileage.⁵ A gap between the title mileage and your repair records can muddy the timeline arguments you’ll be making about the eligibility window.

If Your Used Car Falls Outside the Window

Once the factory warranty is gone or the 24,000-mile line is crossed, the Lemon Law is off the table. Other protections still apply to a used car bought from a dealer.

Washington law implies a warranty of merchantability in every sale made by a merchant. The vehicle has to be fit for ordinary driving and of reasonable quality for its price range.⁶ The rule applies to dealers, not private sellers. A high-mileage cheap car doesn’t have to be perfect, but it has to run and be reasonably safe. Dealers can disclaim this warranty in a written statement identifying what isn’t covered, but if you buy a service contract from the dealer within 90 days of the sale, the implied warranty cannot be waived.⁷

The federal Magnuson-Moss Warranty Act reinforces that. 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 after, the dealer cannot disclaim implied warranties.⁸ The dealer can shorten the implied warranty’s duration to match the written one, but can’t erase it. An “as-is” clause buried elsewhere in the paperwork does not override that.

The FTC Used Car Rule requires dealers who sell more than five used vehicles in a 12-month period to display a Buyers Guide on every vehicle before a customer inspects it. The Guide has to say whether the car is sold “as is” or with a warranty, and if there’s a warranty, what share of repair costs the dealer covers.⁹ The Buyers Guide becomes part of the sales contract. If the Guide promises a warranty and the contract says “as is,” the Guide wins. Read the window sticker before you sign.
