Yes, consumers in Illinois may use the federal Magnuson-Moss Warranty Act to provide them with relief for the purchase of any used car, truck, SUV, or other consumer product. This federal Lemon Law makes no distinction between new and used vehicles. If the vehicle meets the definition of a lemon, it’s covered.
This holds true even though the State Lemon Law in Illinois applies only to new vehicles. As long as you (or a previous owner) report a defect while the vehicle is under warranty, the federal Lemon Law holds the manufacturer responsible for the repairs. And if the manufacturer fails to repair the defects after a reasonable number of attempts, you can seek compensation through the courts.
