The Magnuson-Moss Warranty Act implemented by the Federal Trade Commission expressly prohibits vehicle manufacturers and dealers from voiding your vehicle's warranty or denying coverage under warranty simply because you used an aftermarket part. While manufacturers and dealers are known to deny claims first and ask questions later, it's illegal for them to void your warranty simply for modifying your vehicle. In most cases, reminding dealers and manufacturers of this law will resolve disputes.
T3slaModsmakes no warranty or promises express or implied that your customization will not void warranties. We highly recommend you do your own research, consult with the manufacturer and/or dealer, and in some case even consult with legal counsel before proceeding with a customization if you are concerned about a warranty loss.
