The bill enacts the "Used Motor Vehicles Express Warranties Act," establishing a new chapter in Title 46 RCW that outlines specific express warranty requirements for used motor vehicles sold by dealers in Washington State. It defines key terms such as "manufacturer's warranty," "purchase price," and "used motor vehicle," and sets forth warranty durations based on the vehicle's mileage and age. For instance, vehicles with less than 40,000 miles are covered for 90 days or 3,750 miles, while those with 80,000 miles or more have a warranty of 30 days or 1,250 miles. The bill also mandates that dealers must disclose any open recalls and provides guidelines for warranty breaches, including the dealer's obligation to repair or refund the vehicle.

Additionally, the bill specifies that any agreements waiving or limiting consumer rights under this chapter are void, reinforcing consumer protection. It excludes certain vehicles from warranty requirements, such as those over 20 years old or sold for specific price ranges. The act also clarifies that the express warranty does not cover damages resulting from misuse or neglect after the sale. The provisions of this act will take effect on January 1, 2024.
