Illinois sets repair shop disclosure rules in the Automotive Repair Act, lemon law rules in the New Vehicle Buyer Protection Act, and emissions testing through the Illinois EPA.
What Illinois rules say
- No repair work over $100 may begin without your specific authorization after the required disclosures. (source: Illinois General Assembly)
- A shop must give either a written estimate it cannot exceed by more than 10% without your consent, or a written price limit it cannot exceed without your consent. (source: Illinois General Assembly)
- Estimates must include all charges, including fees for the estimate and diagnostics, and state whether each repair is required or suggested. (source: Illinois General Assembly)
- If a shop takes a car apart to estimate, the estimate must show the cost to put it back together if you decide not to go ahead. (source: Illinois General Assembly)
- Under the lemon law, a reasonable number of repair attempts is presumed after 4 or more tries on the same defect, or 30 or more business days out of service during the warranty period. (source: Illinois General Assembly)
- That presumption applies only if the manufacturer got direct written notice from you and had a chance to fix the defect. (source: Illinois General Assembly)
- Most 1996 and newer gasoline passenger vehicles are subject to emissions inspections after they are four years old. (source: Illinois Environmental Protection Agency)
- The Illinois EPA enforces emissions testing with the Secretary of State by denying plate registration to vehicles that do not comply. (source: Illinois Environmental Protection Agency)
