Illinois Lemon Law

Lemon Law Attorney in Illinois

At Rockpoint Law, lemon law is all we do. We help Illinois drivers hold manufacturers accountable when a new vehicle keeps failing. Illinois has one of the shortest windows in the country and counts its 30 days in business days, not calendar days — two details that quietly decide a lot of claims.

The Law

What Is Illinois' Lemon Law?

Illinois' Lemon Law is the New Vehicle Buyer Protection Act, 815 ILCS 380. It covers new vehicles bought in Illinois, and the statute runs for the first 12 months or 12,000 miles, whichever comes first.

That is a short runway. Illinois ties for the tightest common lemon law window in the country, and once it closes the state statute closes with it. Two things trip Illinois drivers up: the one-year clock, and the fact that the 30-day out-of-service rule is measured in business days, which is a longer stretch on the calendar than it sounds.

The defect still has to substantially impair the use, value, or safety of the vehicle. A minor squeak is not a lemon. An engine that stalls in traffic is.

Eligibility

Do You Qualify for a Lemon Law Claim in Illinois?

Inside the 1-Year / 12,000-Mile Window

The defect has to appear within the first 12 months or 12,000 miles. Illinois ties for the shortest window in the country, so acting early matters more here than almost anywhere.

Four Repairs, Same Defect

The manufacturer's dealer has tried four times to fix the same defect and it is still there. It has to be the same problem coming back, not four unrelated repairs.

Or 30 Business Days Out of Service

The vehicle has been in the shop for 30 business days during the period. Business days skip weekends and holidays, so 30 of them can stretch across six calendar weeks.

Common Defects

Common Problems That May Qualify as a Lemon

Any defect that substantially impairs use, value, or safety can qualify. In Illinois claims we see these most, and Chicago winters and road salt make corrosion and cold-start electrical faults more common.

How It Works

The Lemon Law Process in Illinois

01

Gather Your Paperwork

Collect every repair order, the purchase or lease agreement, and the warranty booklet. In an Illinois claim the repair orders carry the case, and the business-day count only works if the in-and-out dates are documented. Read each order before you leave.

02

Free Case Review

We review the history and tell you honestly whether you qualify under the four-repair rule or the 30-business-day rule. If the record supports neither, we say so.

03

Notice to the Manufacturer

Illinois expects notice to the manufacturer and a final repair chance before the claim proceeds. Send it certified mail so there is a record.

04

Negotiation

We open negotiations with the manufacturer's counsel. Many Illinois lemon claims resolve here, without arbitration or a courtroom.

05

Arbitration or Litigation

If the manufacturer will not deal, we pursue the manufacturer's certified arbitration program or file suit, depending on what the facts and the program require.

Outcomes

What Compensation Can You Receive?

Under the Illinois statute, if the vehicle qualifies you choose the remedy — a refund or a replacement. A manufacturer that offers only one is stating a preference, not the law.

  • A full refund of the purchase price plus collateral charges — sales tax, title, registration, and finance charges — less a reasonable allowance for use
  • Or a comparable replacement vehicle, with the same collateral charges covered
  • Attorney's fees and costs, which the Act shifts to a manufacturer that acted in bad faith — the provision that helps make representation possible
Why Rockpoint Law

Why Illinois Drivers Choose Rockpoint Law

We handle Illinois lemon law matters against the clock, because the one-year window leaves no room to wait. We know which manufacturers settle and which route their claims through arbitration, and that shapes how we build the demand.

We take these cases on the statute's fee provision where it applies, so the cost of bringing the claim does not fall on you first. Send us your repair orders and we will tell you what you have.

Avoid These

Mistakes to Avoid When Dealing With a Lemon Vehicle

  • Confusing business days with calendar days. Illinois counts the 30-day rule in business days — know which one your record hits.
  • Waiting past 12,000 miles because the dealer promises the next fix will be the last. The window is short and unforgiving.
  • Letting an independent mechanic do warranty work. Repairs have to run through an authorized dealer to count.
  • Accepting a goodwill offer tied to a release you did not read. Read it first.
  • Assuming a lease is not covered. Leased vehicles bought in Illinois are covered.
FAQ

Frequently Asked Questions

How long do I have to file a lemon law claim in Illinois?
The statute covers the first 12 months or 12,000 miles, whichever comes first — one of the shortest windows in the country. Your qualifying repairs have to happen inside it.
How many repair attempts does Illinois require?
Four attempts at the same defect, or 30 business days out of service, within the coverage period, plus notice to the manufacturer.
Are the 30 days calendar days or business days?
Business days. Illinois measures the out-of-service rule in business days, which skip weekends and holidays, so 30 of them cover a longer calendar stretch.
Does the Illinois Lemon Law cover used cars?
No. The New Vehicle Buyer Protection Act is a new-vehicle statute. Used vehicles under a written warranty are usually handled through the federal Magnuson-Moss Warranty Act.
Can I choose a refund instead of a replacement?
Yes. Under the Illinois statute the choice belongs to the consumer.
Do I have to use arbitration?
If the manufacturer runs a certified arbitration program, you may have to go through it first. We advise on whether that applies to your vehicle.
Will I have to pay attorney's fees?
The Act allows a consumer to recover reasonable fees and costs where the manufacturer acted in bad faith. We evaluate that with you at the outset.
What if the dealer can't reproduce the problem?
The visit still counts as a repair attempt. Keep the repair order — intermittent faults are common and are not a reason to stop documenting.

Don't face the manufacturer alone.
