Illinois Lemon Law Buyback Calculator

How the Illinois buyback is calculated

Under the Illinois New Vehicle Buyer Protection Act.

• The Illinois New Vehicle Buyer Protection Act lets the manufacturer either replace your vehicle or refund it when a covered defect can't be fixed after a reasonable number of attempts.
• The statute fixes no mileage formula, and eligibility caps coverage at roughly one year or 12,000 miles. Because a qualifying defect must appear that early, and the deduction is keyed to your mileage at the first report, the allowance for use is structurally small, often only a single-digit to low-double-digit percentage of the price.
• Your refund base is the full purchase price plus collateral charges: registration, title and other government fees, finance and interest charges, and dealer-installed options. Under the bare state statute, though, a purchaser's initial sales tax is excluded from the refund (a lessee, by contrast, does recover the taxes paid through the lease).
• The Act itself carries no civil penalty or damages multiplier, so the real leverage comes from the federal Magnuson-Moss Warranty Act, which shifts your reasonable attorney fees onto the manufacturer when you prevail.
• That Magnuson-Moss path can also add your sales tax back in: it recovers the price you actually paid, which typically includes the tax the bare state statute leaves out, so your practical recovery can run higher than the statutory floor.

Illinois lemon law: frequently asked questions

How much can I recover under the Illinois lemon law?

A buyback refunds your full purchase price plus collateral charges (registration, title and government fees, finance charges, and dealer-installed options), minus a small allowance for the miles you drove. Under the bare state statute a purchaser's initial sales tax is left out, though the federal Magnuson-Moss path often adds it back. On a $35,000 car the use deduction is usually modest, so early-life lemons can recover most of the price. Run your numbers through our calculator for a personalized estimate.

Why is the mileage deduction so small in Illinois?

The Illinois statute sets no fixed mileage formula, and to qualify your defect generally has to surface within about one year or 12,000 miles. The deduction is also keyed to your odometer at the first report of the problem, not at surrender. Because that first-report mileage is capped low by the eligibility window, the use allowance stays structurally small, frequently in the single digits to low double digits as a share of the price.

Do I get my sales tax back in Illinois?

It depends on whether you bought or leased, and which path you use. The bare Illinois lemon law statute excludes a purchaser's initial sales tax from the refund, while a lessee does recover the taxes paid through the lease. In practice, the federal Magnuson-Moss path recovers the price you actually paid, which typically includes the sales tax, so many purchasers still get it back. Our estimate flags this difference so you understand the range.

Do I have to pay the attorney out of my recovery?

Usually not. The Illinois lemon law itself has no fee-shifting provision, but the federal Magnuson-Moss Warranty Act does: when you prevail, the manufacturer pays your reasonable attorney fees and costs, typically separate from and on top of your buyback. That fee-shift is the main economic lever in Illinois cases, which is why many lemon law attorneys here take them on contingency, so the fees do not come out of your refund.

How long does an Illinois lemon law claim take?

It varies with the strength of your repair records and the manufacturer's willingness to settle. Many claims resolve through manufacturer arbitration or negotiation in a few months, while contested cases that head toward litigation can take a year or more. Illinois also has a short window to bring a claim, so act promptly once a pattern of repair attempts emerges. A well-documented repair history tends to move a manufacturer to settle faster.
