24-month / 24,000-mile Rights Period

This is the eligibility window for the Washington Lemon Law — whichever comes first.

The 30-month Request for Arbitration filing 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). The underlying defect must have arisen within the 24/24K Rights Period, but the arbitration filing itself can be made up to 30 months from delivery — six additional months after Rights Period closure.

WCPA’s 4-year limitations period

WCPA claims — 4 years from accrual under RCW 19.86.120.

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

Magnuson-Moss — 4 years from delivery under Washington UCC.
