Washington Lemon Law, explained for vehicle owners.
The Washington Lemon Law (RCW 19.118) protects new-vehicle buyers during the first 24 months or 24,000 miles, whichever first occurs. After four repair attempts for the same defect (one for serious safety hazard) or 30 cumulative days out of service, the manufacturer must offer a refund or replacement. Washington operates the New Motor Vehicle Arbitration Board through the Attorney General's office. Attorney fees are recoverable, and the Washington Consumer Protection Act provides parallel remedies for unfair or deceptive practices with treble damages.
Washington's Lemon Law combines a robust state-administered arbitration program — the New Motor Vehicle Arbitration Board operated by the Attorney General's office — with a 24-month coverage window matching Texas and Florida. The Washington Consumer Protection Act (RCW 19.86) overlays as one of the more aggressive state consumer-protection statutes in the country, with treble damages for unfair practices. The combination makes Washington a relatively strong consumer venue for vehicle warranty disputes.

Frequently asked questions
How does Washington's AG arbitration program work?
The New Motor Vehicle Arbitration Board accepts consumer applications, holds hearings before independent arbitrators (typically within 60 days), and issues binding decisions on manufacturers. Filing is free for consumers and the manufacturer pays arbitration costs. Consumers can appeal arbitration decisions to Washington Superior Court.
Is Washington's Consumer Protection Act stronger than other state CPAs?
Generally yes. RCW 19.86 has been interpreted broadly by Washington courts to allow private rights of action for a wider range of consumer harms, with treble damages capped at $25,000. The four-year statute of limitations is longer than many states' CPAs.
Does Washington Lemon Law cover used cars?
Generally no — Washington Lemon Law applies to new vehicles only. CPO vehicles sold with manufacturer warranty may qualify in limited circumstances. For used vehicles, federal Magnuson-Moss and Washington CPA remain available paths. See our used-car coverage guide.
Does Washington Lemon Law cover motor homes?
Yes, including chassis components — Washington's coverage is broader than many states that limit motor home coverage to chassis only. Living quarters disputes still typically require separate analysis under federal Magnuson-Moss.
What if I bought my vehicle in Oregon or Idaho but live in Washington?
Cross-state purchases create jurisdictional questions. Washington courts may apply Washington law to claims involving Washington residents and vehicles registered in Washington, but Oregon or Idaho law may also be relevant. Consult counsel for cross-state analysis.
