How to File a Washington Lemon Law Claim

Step 1 — Recognize the trigger

• Defect substantially impairs use, value, or safety under RCW 19.118.021.
• Defect manifested during the warranty period.
• Manufacturer has had reasonable repair attempts — four for same nonconformity, two for serious safety defects, or 30 cumulative days OOS.
• Within the 24-month / 24,000-mile window AND the 30-month Request for Arbitration deadline.

Step 2 — Document every repair attempt

Pull every repair order.

Step 3 — Send written notice with the final repair opportunity

Under RCW 19.118.041(1)(d):

• Written — certified mail with return receipt is best practice.
• Sent to the manufacturer, not the dealer.
• Use the address designated by the manufacturer for Lemon Law notices (in your owner’s manual or warranty book).
• Identify the defect specifically.
• Demand a final repair opportunity.
• Reference RCW 19.118.041 is good practice.

Step 4 — Allow reasonable time for the final repair

Manufacturer typically has a reasonable time for the final repair. If the defect persists, you can proceed.

Step 5 — Check for a registered informal dispute settlement procedure

Under RCW 19.118.090(2), if the manufacturer has registered a certified procedure with the AG’s office (typically NCDS or BBB Auto Line meeting 16 C.F.R. Part 703), the consumer must use it first. Verify by:

• Checking your owner’s manual or warranty book.
• Calling the manufacturer’s customer-relations line.
• Calling the Washington AG’s Lemon Law Administrator (360-753-6210) to confirm whether the manufacturer has registered.
• Searching NCDS or BBB Auto Line participating-manufacturer lists.

If no registered program exists (most manufacturers have not registered), go directly to AG arbitration.

Step 6 — Choose path: AG Lemon Law Arbitration OR court action

AG Lemon Law Arbitration

• Free, administered by the Washington Attorney General’s Office through the Lemon Law Administrator.
• 60-120 day timeline.
• Three-arbitrator panel from the New Motor Vehicle Arbitration Board.
• Decision binding on manufacturer if you accept.
• No attorney fees.
• Lemon Law remedies only.
• 30-month filing window from delivery.

Court action

• Washington Superior Court — OR federal court (W.D./E.D. Wash.) under Magnuson-Moss concurrent jurisdiction (>$50K).
• Full discovery.
• Discretionary § 19.118.150 Lemon Law attorney fees + mandatory RCW 19.86.090 WCPA attorney fees.
• Parallel WCPA treble damages (capped at $25K per violation).
• 12-24 month timeline.

For most cases with meaningful WCPA exposure, court action produces materially better outcomes.

Step 7 — File the Request for Arbitration (if AG arbitration)

Submit to the Washington AG Lemon Law Arbitration Program:

• Online or by mail through the AG’s Lemon Law Administrator.
• Within 30 months of delivery under RCW 19.118.090(1).
• Include: vehicle information, purchase documents, repair orders, written notice + return receipt, defect description, requested remedy.

Step 8 — File suit (if court action)

Complaint typically alleges:

• Breach of warranty under RCW 19.118.041.
• Breach of implied warranty under RCW 62A.2-314 (Washington UCC).
• Violations of WCPA (RCW 19.86.020) — including the five-element Hangman Ridge test.
• Breach of warranty under Magnuson-Moss.

What you don’t need to do

• You do not need to attempt repairs at independent shops.
• You do not need to keep paying for warranty-covered repairs.

A timing checkpoint

• You’re within the 24-month / 24,000-mile Rights Period.
• You’re within the 30-month arbitration filing window.
• You’ve sent written notice with final repair opportunity.
• You’ve checked for a registered IDS procedure.
• Your repair documentation is complete.

Bottom line

Washington’s procedural rules — especially the written notice and the 30-month arbitration filing window — are unforgiving, but the AG Lemon Law Arbitration Program is the strongest state-run program in the western U.S. Court action unlocks the full WCPA treble damages and mandatory fees, which AG arbitration cannot provide.
