What is a car warranty?

A car warranty, also known as a manufacturer’s warranty, comes with your new or certified used car from the dealer. The warranty protects you from costly repairs caused by manufacturing defects or faulty components.

An extended car warranty, also known as a vehicle maintenance contract, extends protection after your factory warranty expires. You can purchase an extended warranty either from the retailer or from a third party. Manufacturer and extended warranty contracts have similar situations that may void your warranty or result in your claim being denied.

What Voids a Car Warranty?

A manufacturer or supplier may void your warranty if you fail to comply with your contract terms. In some situations, your entire warranty will be void, meaning you will no longer be able to claim for repairs.

Here are some circumstances that can void a car warranty:

  • Vehicle Abuse: If you use your vehicle for anything other than everyday use, such as such as off-road or racing, will void your warranty. This also includes the use of unsuitable liquids.
  • total loss: If your vehicle has received a salvage title following a serious accident, your warranty will be void.
  • Severe environmental damage: Your warranty will no longer be honored if damaged by a natural disaster such as fire or flood.
  • Modified odometer: If the odometer has been tampered with, the dealer will not know the vehicle’s exact odometer reading, which may void your warranty.
  • Aftermarket Changes: For most manufacturers, modifying your vehicle in any way or installing aftermarket components will void your warranty.
  • Improper maintenance: To keep your warranty valid, you are expected to follow and document your factory recommended maintenance schedule.

What causes a warranty claim to be denied?

Other cases will not void your entire warranty, but may result in a repair claim being denied. Many situations can cause this, but these are the most common:

  • Damage caused by using aftermarket repair parts: Use of aftermarket parts may void your warranty or result in your claim being denied. If these parts or repairs cause damage to any component of your vehicle, claims for repair of these parts will be denied.
  • Damage caused by modifications: If your vehicle has modifications that were not installed by the dealer and those modifications cause damage to parts of your vehicle, the damaged components may not be covered.
  • Damage caused by unnecessary repairs: If you took your vehicle to an unapproved repair facility that caused damage to your vehicle, your claim may be denied.
  • Damage from neglect or lack of maintenance: Failure to perform routine maintenance could cause serious damage to your vehicle and your right to have that damage repaired could be denied.

Every automaker and independent supplier has different terms and conditions. Read the fine print of your warranty agreement carefully to understand what may void your warranty and how best to uphold your end of the agreement.

What to do if your warranty claim is denied

If you believe your warranty claim has been wrongly denied, you may be able to find a solution by appealing the denial. However, you will still have to pay for the repairs yourself while the case is being resolved.

If your claim was denied and you are unsure why, you can contact the provider for further explanation. If the situation is serious, you can also take legal action. In some cases, it can also be beneficial to have other cover, especially if you can cancel your contract.

How to avoid problems with your car’s warranty

The best way to avoid problems with your warranty is to read the fine print of your contract and make sure you understand the terms. If you have questions about your warranty, we recommend contacting your dealership or supplier to ask questions.

If you operate your vehicle as intended and carefully follow your vehicle’s maintenance schedule, you are less likely to cause damage and void your warranty. It’s also a good idea to keep track of all the service and repairs performed on your vehicle so you don’t miss out on a paperwork claim.

Should I get an extended warranty?

If your manufacturer is voiding your warranty, you should consider third-party extended warranty coverage. This type of guarantee can be purchased at any time for any new or used vehicle and is independent of your manufacturer’s guarantee. If you choose insurance, read your contract carefully as a contract with a third party can also be void.

When you start looking for coverage, be sure to look at reputable providers with good reviews like Toco. Toco has three levels of coverage and allows you to have your vehicle serviced at any garage.
