A mechanic charged way more than the quote: what to do
Compare the written estimate with the bill; many states require your approval before extra work or going well over the estimate. Ask for an itemized invoice and your old parts. If you need the car, pay by credit card and write “paid under protest,” then dispute the extra charge with your card company and the shop. File a complaint with your state attorney general or auto repair bureau, and use small claims if needed.
Your checklist
- Compare the estimate and the bill
- Ask for an itemized invoice and old parts
- Pay by card “under protest” if needed
- Dispute the charge
- Complain to your state
- Next time: “call me before extra work”
Rather read it? Here’s the whole thing.
Your rights
Many states require auto shops to give a written estimate and get your approval before doing extra work or charging much more than the estimate.
Get the details
Ask for an itemized invoice listing parts, prices and labor hours, and ask who approved any extra work. Ask for your old parts back.
Getting your car back
In many states, a shop can keep your car until the bill is paid (a mechanic’s lien). If you need it, pay by credit card and write “paid under protest” on the invoice.
Push back
- Send the shop a short letter asking for a refund of unauthorized charges.
- Dispute the charge with your credit card company.
- File a complaint with your state attorney general, consumer office or auto repair bureau.
- Use small claims court to ask for a refund.
Next time
Get a written estimate and write “call me before any extra work” on the repair order.
