You have more rights at a repair shop than most people know, and using them is mostly a matter of saying one sentence before the work starts.
The sentence
“Please put it in writing before any work starts.”
That is it. A shop that has no problem with a written estimate is a shop you can probably trust. A shop that talks around it has told you something useful.
Your rights in Illinois
Illinois has a specific law covering repair shops, the Automotive Repair Act. In plain English, here is what it gives you:
- For any repair expected to run over $100, the shop must give you a written estimate before starting — unless you waive it, or there is no face-to-face contact.
- The estimate has to break out parts, labor and any diagnostic charge, describe the parts, and say whether they are new or used.
- You can ask for an itemized estimate, which the shop cannot exceed by more than 10%, or a non-itemized total, which it cannot exceed at all.
- If the job is going to run over because of something they did not expect, they have to get your consent before continuing.
- The final invoice must itemize parts and labor, show the odometer reading, state any warranty, and give the total.
- A shop cannot hold your car under a lien for repairs you never authorized.
If a shop will not make it right, complaints go to the Illinois Attorney General’s consumer complaint form. Other states have their own versions of this law — if you are not in Illinois, look up yours before you need it.
