The Law: Illinois Lemon Law and ICFA
The statutes behind an Illinois lemon-law claim — the New Vehicle Buyer Protection Act (815 ILCS 380), the Illinois Consumer Fraud Act (815 ILCS 505), Magnuson-Moss, and timing rules.
Illinois’s consumer-protection framework for defective vehicles draws from three statutes plus federal warranty law.
The three pillars
- Illinois New Vehicle Buyer Protection Act — 815 ILCS 380. Refund or replacement; court action.
- Illinois Consumer Fraud and Deceptive Business Practices Act (ICFA) — 815 ILCS 505. Civil court action; treble damages potential; mandatory attorney fees.
- Federal Magnuson-Moss Warranty Act — 15 U.S.C. § 2301 et seq. Civil court action; attorney fees.
Most experienced Illinois lemon-law strategy combines the New Vehicle Buyer Protection Act (for substantive refund) with ICFA (for damages and attorney fees).
Topics in this section
- Illinois Lemon Law statute (815 ILCS 380) — Core eligibility, the 12-month/12,000-mile statutory warranty period, the 18-month suit deadline, court action.
- Illinois Consumer Fraud Act (ICFA) — How ICFA overlays the Lemon Law for damages and fees.
- Magnuson-Moss Warranty Act — Federal overlay.
- Repair-attempt presumption — The 4-attempt and 30-business-day thresholds under 815 ILCS 380/3.
- Statute of limitations — Timing under each statute.
Why three statutes instead of one
Illinois’s lemon law is focused (refund/replacement) but doesn’t include built-in fee-shifting. The Illinois Consumer Fraud Act fills that gap with mandatory attorney fees and potential treble damages for willful violations.
This means:
- For straightforward refund cases where the defect arose within the 12-month / 12,000-mile statutory warranty period and suit is filed within 18 months, the Lemon Law alone may be enough.
- For cases with willfulness facts, ICFA in civil court materially amplifies recovery.
- For cases past the Lemon Law window, ICFA (3-year limit) and Magnuson-Moss (4-year limit) provide longer runways.
How they interact procedurally
You can pursue the Illinois New Vehicle Buyer Protection Act and parallel ICFA civil action at the same time — they’re independent statutes. Most Illinois lemon-law attorneys file both together for maximum settlement leverage.
A New Vehicle Buyer Protection Act court action and an ICFA action are typically filed in the same complaint as alternative theories of recovery.
