The Manufacturer Denied My Washington Lemon Law Claim — Now What?

What to do when the manufacturer denies your claim — proceed to AG arbitration or court action with WCPA + Magnuson-Moss.

Manufacturer denial is common and does NOT end your case. Washington provides multiple paths after denial.

Common denial reasons

  • “Not a covered defect.”
  • “Defect cannot be reproduced.”
  • “Outside warranty.”
  • “Owner caused / modified.”
  • “Not enough repair attempts.”

Each denial can be challenged with evidence.

Step 1 — Document the denial

  • Save the denial letter / email.
  • Note the denial reasons.
  • Note the customer-relations case number.
  • Note the date and contact person.

Step 2 — Verify your thresholds

Confirm you’ve met RCW 19.118.041 thresholds:

  • Four attempts on same nonconformity, OR
  • Two attempts on serious safety defect, OR
  • 30 cumulative days OOS.

Plus written notice with final repair opportunity.

Step 3 — Proceed to AG arbitration

If the manufacturer has NOT registered a certified IDS procedure with the AG, file AG Lemon Law Arbitration directly:

  • Free, three-arbitrator panel.
  • 60-120 day timeline.
  • Decision binding on manufacturer if accepted.
  • Must file within 30 months of delivery.

Step 4 — Or proceed to court action

For cases with WCPA willfulness and public-interest impact:

  • Washington Superior Court or W.D. Wash. federal court.
  • Parallel WCPA + Magnuson-Moss + Lemon Law claims.
  • Mandatory RCW 19.86.090 fees on prevailing WCPA.
  • Treble damages capped at $25K per violation.

Step 5 — Get an attorney

For court action with WCPA, attorney representation is essentially free (fees come from manufacturer). Free case review.

Bottom line

Denial is a procedural step, not the end of the case. Most denied cases proceed to AG arbitration or court action — and most consumers prevail when the underlying defect and threshold facts are documented.
