Washington Lemon Law Statute of Limitations

Washington’s lemon-law timing rules involve a Rights Period, a separate arbitration filing window, and two civil-court runways.

The deadlines

Statute	Deadline	Triggered by
Washington Lemon Law (RCW 19.118.021) Rights Period	24 months OR 24,000 miles, whichever first	Original delivery date
Washington Lemon Law (RCW 19.118.090(1)) Request for Arbitration filing	30 months from delivery	Original delivery date
WCPA (RCW 19.86.120)	4 years from accrual	Date violation occurred
Magnuson-Moss / RCW 62A.2-725	4 years from delivery	Original delivery date

24-month / 24,000-mile Rights Period

This is the eligibility window for the Washington Lemon Law under RCW 19.118.021. The defect must manifest within 24 months of delivery OR 24,000 miles — whichever first.

The 30-month Request for Arbitration window

A distinctive Washington rule: the consumer has until 30 months from delivery to file the Request for Arbitration with the AG’s Lemon Law Administrator under RCW 19.118.090(1) — even though the underlying defect must have arisen within the 24/24K Rights Period.

This gives the consumer six additional months after the Rights Period to file. After 30 months, AG arbitration is closed — but court action remains open.

WCPA’s 4-year limitations period

WCPA claims — 4 years from accrual under RCW 19.86.120. Matches NC UDTPA’s 4 years; shorter than NJ CFA’s 6 years or PA UTPCPL’s 6 years.

Magnuson-Moss / RCW 62A.2-725 4-year limit

Magnuson-Moss — 4 years from delivery under RCW 62A.2-725 (Washington UCC).

Practical strategy

Time since delivery	Best avenues
0 – 18 months	All open; AG arbitration is the fastest free path; court for WCPA willfulness.
18 – 24 months	File Lemon Law action / AG arbitration soon.
24 – 30 months	AG arbitration filing window still open (defect must have arisen within Rights Period); WCPA + Magnuson-Moss also available in court.
30 months – 4 years	AG arbitration closed; pursue Lemon Law in Superior Court + WCPA + Magnuson-Moss.
4+ years	Few viable options.

What to do if past the Lemon Law

If past the 24-month / 24,000-mile Rights Period:

1. Don’t give up — the Lemon Law’s 30-month arbitration filing window may still be open, and WCPA’s 4-year limit with mandatory RCW 19.86.090 fees and treble damages (capped at $25K per violation) remains available.
2. Document the timeline carefully.
3. Talk to a Washington lemon-law attorney.

Bottom line

Washington’s framework provides multiple avenues. The 24/24K Rights Period is standard, but the 30-month arbitration filing window stretches the Lemon Law’s practical reach. WCPA’s 4-year limit and Magnuson-Moss’s 4-year limit provide substantial runway for cases involving misrepresentation or federal-court strategy.
