Refund Under Illinois Lemon Law
The most common Illinois Lemon Law remedy — full refund of the purchase price plus collateral charges, minus a reasonable use deduction.
A refund is the most common outcome in Illinois Lemon Law cases — whether through BBB Auto Line or court action. The manufacturer refunds the purchase price plus collateral charges, minus a reasonable use deduction. Note that under 815 ILCS 380/3 the manufacturer elects between refund and replacement; refund predominates in practice (and in negotiated settlements), but it isn’t a remedy the consumer can demand unilaterally.
What the manufacturer must refund
Under 815 ILCS 380/3, the refund includes:
- The vehicle purchase price including dealer-installed options.
- All collateral charges — sales tax, title and registration fees, license fees.
- Incidental damages — alternate vehicle costs, towing.
- The remaining loan balance paid directly to the lender.
The “reasonable allowance for use”
Illinois courts and BBB Auto Line arbitrators typically use:
(Miles driven before defect manifestation ÷ 120,000) × Purchase price
The use deduction is typically 10-25% of the purchase price.
A concrete example
Assume you bought a $42,000 vehicle in May 2026 with:
- $4,500 cash down
- $3,400 tax + $300 registration
- $33,800 financed at 6.9%, paid for 10 months ($600/month)
- Repair attempts at 3,000 / 6,500 / 9,000 / 11,500 miles
- Current odometer at resolution (March 2027): 11,800 miles (just within window)
Recovery breakdown:
| Element | Amount |
|---|---|
| Down payment | $4,500 |
| Tax | $3,400 |
| Registration | $300 |
| Monthly payments × 10 | $6,000 |
| Remaining loan payoff (paid to lender) | ~$30,000 |
| Subtotal | $44,200 |
| Less: reasonable allowance for use (~10%) | –$4,200 |
| Net refund to consumer | $40,000 |
| Plus: ICFA attorney fees (paid separately) | $25,000-$50,000+ |
| Plus: ICFA damages (if applicable) | Variable |
What the manufacturer cannot deduct
- Wear-and-tear beyond the use allowance.
- Market depreciation unrelated to the defect.
- “Diminished value” for cosmetic flaws.
The mechanics
- Settlement or court order documented.
- Manufacturer issues wire transfer to lender for loan payoff.
- Separate wire transfer to consumer for cash portion.
- Consumer signs vehicle title to manufacturer.
- Dealer takes possession.
- Consumer’s loan closes.
Total time: 4-6 weeks.
What about attorney fees?
The Illinois Lemon Law alone doesn’t shift fees. Recovery comes from:
- ICFA § 10a(c) — civil court.
- Magnuson-Moss § 2310(d)(2) — federal or state court.
Bottom line
An Illinois Lemon Law refund — combined with ICFA damages and attorney fees — produces competitive outcomes. The combination is structurally similar to California’s framework.
