Yes. A dealer cannot deny your warranty coverage because routine maintenance or repairs were done by an independent shop, and using aftermarket parts does not void it either. Keep a dated invoice for every service. The exception is work the warranty itself pays for, such as a covered repair or a recall, which the manufacturer can require its own dealers to do.
What the law says
The federal law that governs warranties, the Magnuson-Moss Warranty Act, stops a manufacturer from making your warranty depend on using its own dealers for work you pay for. The Federal Trade Commission, which enforces it, puts it plainly: you do not have to use the dealer for repairs or maintenance to keep your warranty in effect, and it is illegal for a dealer to deny your warranty coverage because you had routine maintenance or repairs done by someone else.
That covers the work most drivers need between warranty claims: oil changes, filters, brakes, tires and alignment, fluids, batteries and inspections.
When you do have to use the dealer
The rule changes when the manufacturer is paying. If the warranty says a repair will be done free, the manufacturer can require you to use the repair facilities it chooses, and if it supplies parts free, it can require its own parts. Recall work is the same: it is carried out through the manufacturer’s dealers.
An extended warranty bought separately is a different product. The FTC calls these auto service contracts, and each one sets its own rules. Some require you to follow the manufacturer’s maintenance schedule, some limit where repairs can be done, and some need approval before work starts. Read yours before you book.
Aftermarket parts
Your warranty stays in effect if you use aftermarket or recycled parts. What can matter is the result: if a defective part, or a part installed incorrectly, damages a component the warranty covers, the manufacturer can refuse to pay for that damage. It has to show that the part caused the damage before it can deny coverage.
The records that protect your warranty
A warranty company can ask for proof that the car was maintained, and without it a claim can be denied. For every service, keep an invoice showing the date, the mileage and what was done. Oil changes, tire rotations, belt replacements, brake pads and inspections are the ones the FTC names. Where it applies, ask for the oil or fluid specification to be written on the invoice, so it can be matched against your owner’s manual.
Following the right schedule for city driving
Most owner’s manuals list two schedules, and short trips, stop and go traffic and long idling usually put a city car on the shorter one. Following the schedule that matches how the car is actually driven is part of maintaining it properly. See oil change intervals for city driving.

Frequently asked questions
Will an oil change at an independent shop void my warranty?
No. A dealer cannot deny warranty coverage because an independent shop changed your oil. Have it done on the schedule in your owner's manual, with oil that meets the specification the manual lists, and keep the receipt.
Do I have to use the manufacturer's parts to keep my warranty?
No. Aftermarket and recycled parts do not void your warranty. If a defective or badly installed part damages a covered part, the manufacturer can refuse to pay for that damage, but it has to show the part caused it.
When do I have to go to the dealer?
For work the warranty pays for. If a repair is covered and free, or the car has a recall, the manufacturer can require you to use its dealers. Routine maintenance you pay for yourself can be done anywhere.
What records should I keep for my warranty?
Keep a dated invoice for every service showing the mileage and what was done, especially oil changes, tire rotations, brake work, belt replacement and inspections. Without records, a warranty claim can be denied.
