Lemon Law in Illinois
If you’re shopping for a vehicle in Illinois, you’re likely feeling the pinch of rising prices. As of May 2025, the average price of a new car in Illinois hovers around $48,397, while used cars average approximately $35,217.

What Is a Lemon Law?
Lemon laws in Illinois are designed to protect car buyers when a vehicle turns out to be defective beyond ordinary repair. To qualify under Illinois’ lemon law, the issue must stem from a manufacturer defect—not from wear, misuse, or aftermarket alterations.
These protections kick in only after the dealer or manufacturer has had multiple chances to fix the problem and failed to do so. If the defect persists despite reasonable repair attempts, you may have a valid lemon law claim under Illinois law.
When Do Illinois Lemon Laws Apply?
Illinois lemon law protections cover new vehicles, including demonstrator models and those sold with a certified pre-owned warranty—provided they meet specific legal requirements. If your car has a substantial defect and the manufacturer has been unable to fix it after multiple attempts, you may have a claim under state or federal lemon laws.
To qualify, all of the following conditions must generally be met:
- Repair Attempts: The manufacturer or dealer has made at least four unsuccessful attempts to repair the same issue, or
- Out of Service: The vehicle has been in the repair shop for 30 or more cumulative days during the first 12 months or 12,000 miles, whichever comes first.
- Timely Reporting: The defect must arise—and be reported—within the first year or 12,000 miles of delivery.
- Substantial Impairment: The problem must substantially impair the vehicle’s use, value, or safety.
How Do You Ensure the Application of Lemon Laws?
To strengthen your claim under Illinois lemon law, it’s essential to follow a few best practices from the beginning. These steps not only preserve your rights but can also improve your chances of receiving a fair resolution—whether that means a refund, a replacement, or another remedy under the law.
Here’s what to keep in mind:
- Use the Manufacturer’s Authorized Repair Center – Always bring your vehicle to the dealership or an authorized repair facility. If you choose an independent mechanic, the manufacturer may argue they aren’t liable for that work.
- Document Everything – Keep records of each visit to the repair shop, including dates, issues reported, repairs attempted, and how long your vehicle was out of service. These logs are crucial if your case ends up in arbitration or court.
- Know the Timeline – Illinois lemon law covers new vehicles for 12 months or 12,000 miles, whichever comes first. If a defect emerges within this window, the dealer gets four chances to fix it.
According to the Illinois Attorney General’s Office, if the problem persists, you may be entitled to:
- A replacement vehicle of comparable value
- A manufacturer buyback, adjusted for the miles driven before the issue became disqualifying
What Exactly Are Consumers Entitled To Under Lemon Laws?
If your vehicle qualifies under Illinois lemon law, you’re not just entitled to frustration—you’re entitled to compensation. When a car repeatedly fails to meet performance or safety standards, and repairs haven’t solved the issue, the manufacturer must make it right. That typically means either providing a replacement vehicle or issuing a refund.
However, under Illinois law, manufacturers are allowed to deduct a usage fee based on the number of miles driven before the defect was reported. Even so, your refund should still account for the many costs you’ve already incurred, such as:
- Down payment – The initial amount you put toward the purchase.
- Registration – Any fees paid to register your vehicle with the state.
- Taxes – Sales tax and related fees from the original purchase.
- Car rentals – Expenses related to renting a car while your vehicle was in the shop.
- Monthly payments – Loan payments made before the vehicle became unusable.
- Tow expenses – Costs for transporting your vehicle to and from the dealership.
- Attorney costs – In many cases, legal fees are covered if you win your case.
Do Lemon Laws Apply to Used Vehicles?
In Illinois, lemon laws primarily protect buyers of new vehicles, but that doesn’t mean used car buyers are entirely without recourse. If your used car came with a warranty—such as one from a certified pre-owned program—you may still have legal standing.
Illinois also requires dealers to provide at least a 15-day or 500-mile limited powertrain warranty on many used vehicles. That said, this protection excludes vehicles with more than 150,000 miles on the odometer.
When Should You Hire a Qualified Illinois Lemon Law Lawyer
If you’ve already given the dealership a fair chance to fix your car—and the problem persists—it may be time to escalate.
Illinois law doesn’t require you to tolerate repeated failed repairs. If your vehicle has been in the shop multiple times for the same issue or has been out of service for a significant number of days, it’s worth speaking with a lemon law attorney.
How Does the Lemon Law Litigation Process Work?
Pursuing a lemon law claim in Illinois often requires more than just persistence—it takes strategic legal action. A knowledgeable attorney can help you navigate the process with clarity and confidence. If you partner with a qualified Illinois lemon law lawyer, here’s what you can generally expect:
- Free Case Review – Most attorneys begin with a no-cost evaluation. They’ll review your repair history and warranty documents to determine whether your claim qualifies under state or federal lemon laws.
- Claim Preparation and Filing – Your lawyer will organize the necessary documentation and submit a formal claim to the manufacturer, outlining their failure to fix the vehicle after multiple attempts.
- Escalation if Necessary – If the manufacturer refuses to honor your claim, your attorney may pursue formal legal action in court to secure compensation.
- Settlement Negotiation – If your case settles before trial, the manufacturer is typically responsible for covering your legal costs, including your attorney’s fees.
- Contingency-Based Fees – Reputable Illinois lemon law attorneys usually work on a contingency basis. That means you don’t pay unless you win—either through settlement or court judgment.
When it comes to where your case is heard, the amount of your claim plays a role. In Illinois, small claims courts handle cases involving damages up to $10,000, while anything above that must be brought before a circuit court judge (Illinois Courts). Working with an experienced attorney ensures your case is filed in the proper venue and meets all procedural requirements.
