    Will Installing Aftermarket Parts Void My EV Warranty?

    A questions we get is "will installing your parts void my factory warranty?"

    The answer is NO.

    Per the Federal Trade Commission website (consumer.ftc.gov), an 'aftermarket' part is a part made by a company other than the original vehicle manufacturer or the original equipment manufacturer. Simply using any aftermarket part does not void your warranty. Under the Magnuson-Moss Warranty Act, it is illegal for companies to void your warranty or deny coverage under the warranty because an aftermarket part is installed.

    When accessorizing, customizing, or personalizing your vehicle with aftermarket parts, your warranty claim cannot be automatically denied, nor can your warranty be voided, if you install non-OEM parts in your vehicle. The dealer must prove the aftermarket parts caused the failure at hand. For example, if your front driver window fails, your vehicle’s warranty claim can’t be denied because you installed an aftermarket tire pressure sensors that are different from OEM (Original Equipment Manufacturer) parts. More importantly, if an air suspension unit or an electric drive motor fails and you have an aftermarket wheel installed, the dealership/manufacturer would have to prove the aftermarket wheel caused the suspension unit failure or the drive motor to fail in order to deny a warranty claim. In these types of scenarios, the dealership/manufacturer should have no reason to deny your claims.

    Still, if it turns out that the aftermarket part was itself defective or wasn't installed correctly, and it causes damage to another part that is covered under the warranty, the manufacturer or dealer has the right to deny coverage for that part and charge you for any repairs. The FTC says the manufacturer or dealer must show that the aftermarket part caused the need for repairs before denying warranty coverage.
