Guide
Start with the hard truth: in most states the lemon law's refund/replacement remedy is a new-car remedy. But 'used' is not one situation. You may have bought a car still under the manufacturer's new-car warranty; a certified pre-owned car with a warranty issued at your sale; a car transferred to you during the warranty; or a car with no manufacturer warranty at all. Each has a different legal home.
New York built a real used-car law (§198-b) with dealer warranty tiers. California's Rodriguez decision sorts used cars by whether a new-car warranty was issued with the sale. A dozen-plus states (Minnesota, Connecticut, Vermont among them) extend coverage to vehicles still under the manufacturer's warranty or transferred during it. And everywhere, the federal Magnuson-Moss Act covers warranted used cars with no attempt quota.
The checker asks which used-car situation yours is and routes accordingly. What it will never do is score a used car under new-car numbers to make the answer prettier — that is the error this brand exists to correct.
