Car warranties cover a wide array of things that could go wrong with your car, but some common mistakes could void your warranty and cost you in the long run. It’s important to understand what things may void your new car’s warranty, so that you don’t risk unintentionally voiding it. Whether you are making aftermarket modifications to your car, or simply neglecting routine maintenance, understanding what you need to do to keep your warranty is essential. Let’s take a look at some of the most common things that can void your car’s warranty.


Regular maintenance, such as monitoring and changing your car’s oil at your car manufacturer’s recommended intervals is an important part of owning a car, and can have an impact on your car’s warranty. Also, only using the fluids your car manufacturer recommends is essential and will prevent any warranty issues. While it may seem like a good idea to use a cheaper fluid in your car, it may cost you in the long run, damaging your car and voiding your warranty.

Wheels and Tires

Maintaining and replacing your car’s tires is another essential part of car maintenance. Not only is staying on top of tire replacements and alignment checks important, but also carefully considering what tires you put on your car is essential, as putting the wrong tires on could void your warranty. Adding a lift or lower kit to your car can also void your warranty, as it compromises the integrity of the car.

Neglect/Lack of Maintenance Receipts

Neglecting to do routine maintenance on your car can also void your warranty. If you choose to do maintenance work yourself, it’s essential you keep your receipts to prove the work was done. Things like oil changes and brake pad replacements can be done at a shop, and will be recorded as proof, but receipts for your oil and brake pad purchases can serve the same purpose.


Aftermarket modifications to your car can also void your warranty, so carefully consider any alterations you want to make to determine if they are a good idea. For specifics on what modifications may void your warranty, consult your car’s owner’s manual.


Misusing your car can also void it’s warranty, by possibly causing damage to the engine. A common example of misuse is towing. Whether your car isn’t meant to tow anything, or you are towing more than your manufacturer recommends, towing outside of those recommendations can not only damage your car, but also void your warranty. If you are unsure about the towing capacity of your vehicle, check the owner’s manual to prevent any issues.

Salvage Title

If you car was involved in a severe accident and has been declared a total loss, the warranty is completely voided. In this scenario, you’ve been given a salvage title, and the car is considered totaled.

Warranties help protect car owners, and can save you precious money in the long run, but be sure to familiarize yourself with what things can void your warranty. If you are unsure what other things may void your car’s warranty, check in your owner’s manual for a more detailed description.
