Auto Repair Rights in Michigan
What a repair shop in Michigan must tell you before it works on your car, how far a bill can go over the estimate, and what to do about an overcharge, cited to the statute.
Your rights and the rules in Michigan
The estimate rules, going over the estimate, your old parts, and how the rule is enforced.
| Written estimate | Before a registered facility starts work, it has to hand you a written estimate that itemizes the labor and parts as closely as possible. You authorize the work at that price. The shop cannot make you waive the estimate as a condition of the repair. |
| Going over the estimate | The final bill cannot go past the estimate by more than 10%, or $50, whichever is smaller, unless the shop calls you and gets your knowing consent after it learns the estimate is short and before it does the extra work. Consent can be written or oral, but the shop has to get it up front, not spring the higher number on you at pickup. |
| Get your old parts back | You have the right to get your old parts back or to see them, and the shop has to post a sign at the entrance telling you so. You indicate whether you want them returned automatically or on request. Parts too large or heavy to hand back, and parts the shop must send to a manufacturer for warranty or exchange credit, are the exceptions. |
| Itemized invoice | When you pick up the vehicle, the shop must give you a written statement, or invoice, that lists the work done, the parts installed, and the charges. Keep it; it is your proof if the bill and the estimate do not line up. |
| Shop's lien on your car | A Michigan repair shop can hold your vehicle under a garage keeper or artisan lien until the authorized bill is paid. The lien only covers work you actually agreed to, so a charge that broke the estimate rule is a charge you can dispute rather than simply pay to get the car back. |
| How it is enforced | The Motor Vehicle Service and Repair Act is enforced by the Bureau of Automotive Regulation in the Business Compliance and Regulation Division of the Michigan Department of State, working with the Michigan State Police. The Bureau licenses facilities, certifies mechanics, investigates complaints, and can suspend or revoke a facility license. |
| Statute | Mich. Comp. Laws §257.1301 to §257.1340 (Motor Vehicle Service and Repair Act) |
What you can do right now
Concrete, neutral steps if a Michigan shop overcharged you or did work you never approved. This is legal information, not legal advice.
- Get the written estimate before any work
Ask for the itemized written estimate and keep your copy. Do not leave the vehicle until you have it, and do not sign anything that waives your right to it.
- Do not approve overages past 10% without a call
Tell the shop it must phone you before charging more than 10%, or $50, over the estimate. If it billed extra without your consent, you can refuse to pay the part that broke the cap.
- Ask for your old parts
Request the replaced parts back, or ask to see them, so you can confirm the work matched the invoice. The shop is required to keep them available except for the large or warranty exceptions.
- File a complaint with the Bureau of Automotive Regulation
If the shop broke the estimate rule or the invoice does not match the work, send the estimate and invoice to the Bureau of Automotive Regulation at the Michigan Department of State.
If a shop billed you for work you never approved, you can file a complaint. This is the official channel that handles auto-repair disputes.

What Michigan drivers get wrong
Michigan runs auto repair through the Motor Vehicle Service and Repair Act, MCL 257.1301 to 257.1340, which the Department of State enforces rather than leaving disputes to general consumer law. Any shop that repairs cars for pay has to be a registered facility, and the mechanics doing the work have to be certified in their category. The core protection is the written estimate: the shop gives it to you before it touches the vehicle, and it cannot bill more than 10%, or $50, whichever is lower, above that number without calling you first for consent. Replaced parts stay yours, and a sign at the door has to say so. When you pick the car up, you get a written invoice listing the work, the parts, and the charges. If a shop skips the estimate, blows past the cap, or hides the parts, the Bureau of Automotive Regulation is where the complaint goes.
Common questions
Does a Michigan mechanic have to give me a written estimate before starting?
Yes. Under the Motor Vehicle Service and Repair Act a registered facility must give you a written estimate that itemizes labor and parts before it begins the repair, and it cannot force you to waive that right to get the work done.
How much over the estimate can a Michigan shop charge me?
No more than 10%, or $50, whichever is smaller, without your consent. Past that, the shop has to contact you and get your knowing written or oral approval before doing the extra work. A charge that broke this rule is one you can dispute.
Can I get my old parts back after a repair in Michigan?
Yes. You have the right to receive or inspect the replaced parts, and the facility must post a sign at its entrance stating that. The only exceptions are parts too large or heavy to return and parts that must go back to a manufacturer for warranty or exchange credit.
What do I do if the final bill in Michigan is much higher than the estimate?
Point to your written estimate and refuse to pay the portion that exceeds the 10% or $50 cap if the shop never got your consent for it. Keep the estimate and the invoice, and file a complaint with the Bureau of Automotive Regulation at the Michigan Department of State.
Does the shop have to be licensed in Michigan?
Yes. Any business repairing motor vehicles for compensation must be a registered repair facility with the Department of State, and its mechanics must be certified in the categories they work on. The facility license has to be displayed where customers can see it.
