Washington's lemon law can reach a used car, but only a young one. The Motor Vehicle Warranties Act, RCW 19.118, protects a "subsequent transferee" who buys a vehicle within two years of its original delivery or its first 24,000 miles, whichever comes first, while the manufacturer's written warranty still applies. Buy anything older and the lemon law is out of the picture, and what's left is the implied warranty a Washington dealer has to give you unless you knowingly waive it, the Consumer Protection Act and whatever the dealer wrote down.
I went through the full text of RCW 19.118 on the Legislature's site and the Attorney General's used-car buying page on Saturday evening, October 17, 2026. The second-owner rule was more generous than I expected. Treat this as general information, not legal advice, and talk to a Washington attorney before you send a demand letter.
Who the Washington lemon law covers
The definitions section, RCW 19.118.021, sets an "eligibility period" ending two years after original delivery to the first consumer or at 24,000 miles. A subsequent transferee is someone who gets the vehicle inside that window, with the manufacturer's written warranty still in force, where the car met the definition of a new motor vehicle when it was first sold at retail. The first retail sale must have been by a Washington new-car dealer or leasing company, and fleets of ten or more and trucks rated 19,000 pounds or more are excluded.
So a 2025 crossover with 14,000 miles that you bought off a Washington lot last spring might qualify. A 2019 sedan with 60,000 miles won't, however bad it is. If you choose a refund as a subsequent transferee, the statute uses your purchase price, not the original buyer's.
How a car becomes a lemon in Washington
Under RCW 19.118.041, the manufacturer is presumed to have had a reasonable number of attempts if the same serious safety defect was diagnosed or repaired two or more times, the same nonconformity four or more times, the car was out of service 30 calendar days total (at least 15 under the written warranty), or two different serious safety defects came up within 12 months. In each case at least one attempt has to happen while the written warranty is in effect. After your written request, the manufacturer has 40 calendar days to replace or repurchase, and the refund is reduced by an offset worked out from the miles you drove before the first repair attempt.
Manufacturers must join the AG's arbitration program if you ask within 30 months of original delivery and the AG accepts the case. One trap: the chapter says consumers have no cause of action against dealers under it. Your lemon claim goes against the manufacturer, and complaints about how the dealer treated you go under other laws, including the dealer licensing chapter, RCW 46.70.
Older used cars: implied warranty and as-is
For most used cars, the protection that matters is the implied warranty of merchantability. The Attorney General's used-car page says you give that up only if the dealer explicitly discussed warranty terms with you, the waiver lists the parts and qualities not covered, you didn't buy a service contract, and you knowingly took on the repair risk. Buy a service contract from the same dealer within 90 days, or get a limited written warranty, and the implied warranty can't be waived. WashingtonLawHelp, run by the Northwest Justice Project, says the same and notes small claims court handles damages up to $10,000.
Don't expect a cooling-off period, though. The AG calls the three-day right to cancel "the most common myth of consumer law," and says there is none when you buy at a dealer's main place of business. What Washington does have is the bushing rule in RCW 46.70.180: if your deal depends on financing, the dealer has four calendar days, not counting weekends or holidays, to accept or reject it, and generally can't come back weeks later to cut your trade-in value. Our as-is used car explainer covers the federal Buyers Guide side, which the FTC Used Car Rule requires on the window.
Lemon buybacks for sale in Washington
Washington tracks buybacks closely. RCW 19.118.061 says that before a returned vehicle is resold, the seller must attach the AG's resale window notice and hand the buyer a signed resale disclosure form naming the defect and the title brand. The Department of Licensing then issues a title branded to show the car was returned and whether the defect was fixed, and buybacks from other states get their own brand. A middleman who drops the paperwork can be on the hook to indemnify you or buy the car back. Our post on the lemon law buyback title brand shows how these look on paper.
Flood and wreck cars cross the Columbia too. Read our Washington salvage and rebuilt title rules and the Washington vs Oregon salvage title comparison, and use our Washington private sale title guide if a person is selling. California works very differently; see the California used car lemon law post.
Before you sign in Washington
Write down the in-service date and current miles, because those two numbers decide whether RCW 19.118 is even possible for you. Then run the VIN through NMVTIS for brands and pull your own history report instead of reading the one the dealer printed, which may be weeks old or not for that VIN at all. CarVins is a licensed CARFAX and AutoCheck reseller with no affiliation to CARFAX, AutoCheck, Experian or the state. As of mid October 2026, a guest report runs about $5.50, members pay around $4.50, and a two-report bundle is near $6.75, while retail usually sits between $39.99 and $44.99. Your checkout total is the number that counts.
