Washington's Claim Categories and Requirements
Washington uses four distinct claim categories. Each has specific requirements that must be met for a successful lemon law claim.

Key Definitions
- Nonconformity: A defect that substantially impairs use, value, or safety, making the vehicle unreliable, unsafe, or diminished in resale value
- Serious safety defect: A life-threatening malfunction that impedes the driver's ability to control the vehicle or creates a risk of fire or explosion
- Eligibility period: 2 years or 24,000 miles from original delivery, whichever comes first
Consumer Remedies: Repurchase vs. Replacement
When a vehicle qualifies as a lemon under Washington law, the manufacturer must repurchase or replace the vehicle.
Option 1: Repurchase (Buyback)
The manufacturer must refund:
- Purchase price: Cash price appearing in sales agreement
- All collateral charges: Sales tax, use tax, arbitration fees, unused license/registration/title fees, finance charges, prepayment penalties, credit insurance costs, transportation charges, dealer prep, service contracts, undercoating, rustproofing
- Incidental costs: Towing charges, costs of alternative transportation
Option 2: Replacement Vehicle
The manufacturer must provide:
- A new motor vehicle identical or reasonably equivalent to the original
- As the original existed at time of purchase or lease
- Including any service contract, undercoating, rustproofing, and factory or dealer installed options
Reasonable Offset for Use
The manufacturer may deduct a reasonable offset for use. Under RCW 19.118.041, this is calculated as:
Offset = (Purchase Price x Miles at First Repair) / 120,000
For Subsequent Transferees
- If selecting repurchase, "purchase price" means the subsequent purchase price
- If selecting replacement, "purchase price" means the original purchase price

How to File a Lemon Law Claim in Washington
Washington provides a free arbitration process through the Attorney General's Office.

Step 2: Send Written Request to Manufacturer
Before filing for arbitration, you must send a written request to the manufacturer asking for repurchase or replacement. The manufacturer has 40 days to respond and attempt resolution.
