What Can Void A Car Warranty? [Partial & Complete Voids]

After spending the extra costs associated with extended warranties, the last thing you want to see is the phrase “Claim Denied.”
It helps to be prepared, so we’ll give you a rundown of the most common things that can partially or completely void your car warranty.
In addition, we’ll show you some tricks to avoid any warranty claim issues.
What Does A Partial Warranty Void Mean?

A partially voided warranty is when a warranty issuer will only cover a part of a repair or a partial parts replacement.
There are several reasons why a warranty could be partially voided. Usually, a warranty will be partially voided if the vehicle driver has taken an action that is forbidden by the warranty, which we’ll cover later.
Things That Can Void Your Entire Warranty
Here’s a look at some of the common actions that can lead to a complete void of a vehicle warranty:

- Off-road driving
- Overloading
- Racing
- Reckless driving
- Natural disasters such as fire, earthquakes, or hurricanes
- Using improper fluids
- Adding disallowed modifications
If you are in doubt, you should contact the issuer of the warranty. For instance, if you want to go off-roading, you should contact the warranty issuer and see what type of off-roading activities are allowed.
What Can Cause A Warranty Claim To Be Denied?
It’s a good idea to know why your warranty claim can be denied. Sometimes, you can be denied because of the nature of the coverage. Other times, your warranty can be denied because of specific actions you have taken.

Here’s a look at the top reasons why a warranty claim can be denied:
- The part of the component is not covered under the warranty
- The area that needs service was misused or abused
- There are disallowed aftermarket modifications made to the vehicle
- The vehicle was damaged by a natural disaster
- Your vehicle has been salvaged
- There were unnecessary repairs made
- The repair shop chosen overcharged for the service
- There are signs of a lack of maintenance
- The area that is repaired was a pre-existing condition
What If My Warranty Claim Is Denied?
If your warranty claim has been denied, you don’t have to panic. That’s because just about every warranty company has an appeals process. Each process is going to be different depending on who issued the warranty.
Be sure to file the appeal right away. Additionally, be prepared to have any paperwork or evidence that can support your claim. For instance, if your claim was denied because of lack of maintenance, then be sure to gather all of your vehicle’s maintenance records.
How To Avoid Warranty Claim Issues

Make sure you don’t have to deal with warranty headaches. Here are eight steps that you can take to ensure that you don’t have to deal with warranty claim issues:
- Choose a warranty provider with an excellent reputation
- Carefully review the contract and ask any questions before you sign
- Keep up with the vehicle’s regular maintenance schedule
- Save all of your receipts associated with your repairs
- Address any mechanical issues right away.
- Double-check your coverage
- Wait for warranty authorization before you have the vehicle repaired.
If you still have any questions about your warranty, consult your warranty website or contact the warranty issuer’s customer service team.
What Modifications Do Not Void Your Car Warranty?
Not all warranties are the same. However, some common modifications that will not void your warranty include:

- Suspension
- Wheels
- Brakes
- Exterior modifications
- Sway bars
- Short shifter
Be sure to check the warranty to see which specific modifications will not void your warranty.
