Car Service Records: What to Keep for Warranty and Resale

informational·Informational·Published January 28, 2026·Updated October 24, 2026

Which car service records should you keep?

Keep a record of every maintenance job and every repair on your car, from oil changes to new brake pads. In the U.S., the Federal Trade Commission says these records help you show that you properly maintained the vehicle when you need to use your warranty.

Sources, as of 2026: the U.S. Federal Trade Commission (FTC) consumer guidance on auto warranties and its 2011 consumer tip on warranty service records, Quebec's Office de la protection du consommateur, one vehicle maker's 2022 U.S. owner handbook and one maker's 2023 Canadian warranty booklet. The two maker documents speak only for their own vehicles.

Service records to keep in your file

Routine maintenance: each oil change, tire rotation and belt replacement.
Brake work: each set of new brake pads.
Repairs: each repair, with the invoice from the shop that did the work.

Independent shop or dealer: the warranty rule where you live

You live in the U.S. and your car is under warranty

Under federal rules, a dealer cannot legally deny your warranty coverage because someone else did the routine maintenance or repairs. You can use an independent shop for that work.

You live in Quebec and your used car, bought from a dealer, is under the maker's warranty

Quebec's Office de la protection du consommateur says that you can have the maintenance done at the garage of your choice.

You live in another province or territory

Ask your provincial or territorial consumer protection office which rule applies to your warranty before a car under warranty goes to an independent shop.

Does maintenance help when you sell or trade in the car?

A 2022 U.S. owner handbook from one maker says that maintenance on the schedule in the owner's manual may help increase the value you receive when you sell or trade in the vehicle. Keep the file complete, and pass the maintenance receipts and records to each later owner. If the car had crash damage, also read how to protect resale value after a collision.

Frequently Asked Questions

Do I need the receipt for every oil change, even from a quick-lube shop?

Yes. Keep all service records and receipts, no matter who does the service. That includes the receipt from a quick-lube shop or an independent garage, not only the receipt from the dealer, for each oil change. Ask for the receipt at each visit.

Should I keep inspection reports with my service records?

Yes. Keep each inspection report with your maintenance and repair records. Record each inspection the same way as an oil change, a tire rotation, a belt replacement or a set of new brake pads.

Why do maintenance receipts matter if a part fails?

Because the receipt is your proof that the maintenance was done. In one maker's 2023 Canadian warranty booklet, receipts matter when the maker asks whether poor maintenance caused a part to fail.

Do I have to keep the garage invoices in Quebec?

Yes, if your used car, bought from a dealer in Quebec, is under the maker's warranty. In that case you must keep each invoice that the garage gives you, and you can show the invoices to the dealer or the maker.

Do high mileage and crash damage lower resale value?

Yes. Higher mileage speeds the loss of value, and crash damage often lowers the value of a car too. After a crash repair, keep the repair invoices with your service records, so that the next owner can see which parts were repaired.
