Refund Under Washington Lemon Law

The most common Washington Lemon Law remedy — full refund plus Washington sales tax and collateral charges, minus a reasonable use deduction, with WCPA treble damages and mandatory RCW 19.86.090 fees in court.

A refund is the standard remedy in Washington Lemon Law cases.

What the manufacturer must refund

Under RCW 19.118.041(1):

  1. The full vehicle purchase price including dealer-installed options.
  2. All collateral charges — Washington state sales tax (6.5% state + local; total typically 8.5-10.5%), license, registration, title fees.
  3. Incidental damages — towing, rental, lost time.
  4. The remaining loan balance paid directly to the lender.

The “reasonable allowance for use”

Typical formula:

(Miles driven before first repair attempt ÷ 120,000) × Purchase price

Typically 10-20% of purchase price. Washington uses miles driven before the first repair attempt — miles accumulated during repair attempts or while operating a known-defective vehicle do not count.

Washington sales tax

Washington has no state income tax but applies a 6.5% state sales tax plus local rates (typically 1.8-3.8%), reaching total rates of:

  • King County (Seattle/Bellevue): 10.25-10.4%.
  • Pierce County (Tacoma): 10.0-10.3%.
  • Snohomish County (Everett): 9.8-10.6%.
  • Spokane County: 8.9%.

On a $42K Seattle vehicle, total sales tax can exceed $4,300 — fully reimbursable as a collateral charge.

A concrete example

Assume you bought a $42,000 vehicle in May 2026 in Bellevue:

  • $4,500 cash down
  • $4,305 sales tax (10.25% Bellevue) + $200 title/registration = $4,505 collateral charges
  • $33,995 financed at 6.9%, paid for 14 months ($600/month)
  • Repair attempts at 6,000 / 14,000 / 21,000 miles (Puget Sound commute hits these fast)
  • Current odometer at resolution (May 2027): 24,000 miles (within 24/24K window)

Recovery breakdown:

ElementAmount
Down payment$4,500
Sales tax$4,305
Title + registration$200
Monthly payments × 14$8,400
Remaining loan payoff~$28,000
Subtotal$45,405
Less: reasonable allowance for use (~15%)–$6,300
Net refund to consumer$39,105
Plus: § 19.118.150 Lemon Law fees (if groundless/bad-faith defense)Variable
Plus: WCPA treble damages (capped $25K/violation, court only)Up to $25K per violation
Plus: RCW 19.86.090 mandatory WCPA attorney feesSeparate fee award

What the manufacturer cannot deduct

  • Wear-and-tear beyond use allowance.
  • Market depreciation unrelated to defect.
  • “Diminished value” for cosmetic flaws.
  • Negative equity rolled into the financing.

The mechanics

  1. AG arbitration decision, settlement, or court order documented.
  2. Manufacturer wire transfers to lender for loan payoff.
  3. Separate wire transfer to consumer for cash component.
  4. Consumer signs vehicle title to manufacturer.
  5. Dealer takes possession.
  6. Loan closes.

Total time: 4-8 weeks for AG arbitration; 4-6 weeks for court settlement.

What about attorney fees?

§ 19.118.150 provides discretionary Lemon Law attorney fees (only where the manufacturer’s defense was groundless / not in good faith). RCW 19.86.090 (WCPA) provides mandatory attorney fees on prevailing — this is the load-bearing fee engine. Magnuson-Moss provides federal-court fees.

AG arbitration does NOT award attorney fees — only refund/replacement.

When refund makes sense

  • The defect is persistent.
  • The vehicle has substantial diminished value.
  • You want a clean break.

What if the manufacturer won’t comply with an AG arbitration decision

The decision is binding on the manufacturer once the consumer accepts. Non-compliance is enforced through court action, where the manufacturer faces additional WCPA and attorney-fee exposure.

Bottom line

A Washington Lemon Law refund — combined with WCPA treble damages capped at $25K per violation for cases with public-interest impact and willfulness, and mandatory RCW 19.86.090 fees in court action — produces strong consumer-favorable outcomes. AG arbitration produces only the refund component; court action unlocks the full statutory exposure.
