Illinois Lemon Law: Does It Cover Used Cars?

Lemon laws in Illinois are regulations that generally aim to protect consumers who purchase a defective car or other consumer products and services, such as computers, phones, and even animals. Typically, the term lemon is applied to defective motor vehicles like trucks, motorcycles, SUVs, vans, all-terrain vehicles, and cars, but there are other “lemon laws” in Illinois for many different consumer products. In addition to the lemon laws in Illinois, there are also federal lemon laws that have protected every U.S. citizen in any state since 1975. The federal lemon law largely covers mechanical defects (i.e., defects relating to vehicles). However, the lemon laws in Illinois offer a wider coverage and can even apply to business and commercial motor vehicles.

What Is the Lemon Law in Illinois? 

The lemon law Illinois is a consumer protection law that aims to help consumers who inadvertently purchase defective goods, primarily vehicles. The law in Illinois mandates that the manufacturer must make a reasonable effort, which is typically four or more attempts to repair the vehicle prior to a reasonable time limit. If the manufacturer fails to do this, the law requires that it either refund the consumer’s money or replace the defective vehicle with a comparable new motor vehicle. 

How Does the Lemon Law in Illinois Work?

Lemon laws in Illinois exceed the contractual protections afforded to consumers in warranties. A general requirement in Illinois lemon law is that the product (vehicle) must have been purchased with such warranty as is eligible under the law. There must be a material defect with the vehicle—meaning that the defect affects the vehicle’s ability to function.This can be a specific or generic defect. Additionally, the consumer must give the manufacturer or seller the opportunity to repair the defect.

If, however, a consumer has an agreement to purchase a vehicle “as-is,” that agreement is taken as an acceptance and assumption of the risk of potential defects by the buyer. What this means is that the consumer is willing to purchase the product regardless of any possible defects—whether known or unknown—and that the buyer waives the right to seek reimbursement of the full purchase price (often minus collateral costs) from the seller (authorized motor vehicle dealer) or manufacturer.
