Illinois Lemon Law Case Value Calculator

Lemon law recovery typically equals the full purchase price of the vehicle minus a mileage offset — a deduction for miles driven before the first defect appeared. Most states use a formula dividing pre-defect mileage by 120,000 miles and multiplying by the purchase price. You may also recover incidental damages, and in many states the manufacturer must pay your attorney fees.

A vehicle is generally considered a lemon if it has a substantial defect covered by the manufacturer's warranty that the dealer cannot repair after a reasonable number of attempts. Most states define 'reasonable' as 3–4 repair attempts for the same defect, or 30+ cumulative days out of service, within the first 18–24 months or 18,000–24,000 miles of ownership.

Coverage varies significantly. About a dozen states — including California, New York, Connecticut, Massachusetts, and Minnesota — have used vehicle lemon laws. Most states only cover new vehicles purchased with a manufacturer's warranty. If your state doesn't cover used vehicles, you may still have remedies under the federal Magnuson-Moss Warranty Act.

While not required, an attorney is highly recommended. Most state lemon laws include attorney fee-shifting — the manufacturer pays your attorney fees if you prevail. This means lemon law attorneys typically handle cases on contingency at no upfront cost. An experienced attorney can navigate manufacturer arbitration and significantly increase your recovery.
