The core principle is based on the U.S. Magnuson-Moss Warranty Act. Tesla's warranty policy largely follows this act. Its essence is that a manufacturer cannot automatically void the entire vehicle's original warranty simply because the owner has installed aftermarket parts. However, if this third-party accessory directly causes damage to a specific component of the vehicle, Tesla may deny warranty coverage for that particular damage.
Our products have passed safety tests. However, please note that any modifications involving the vehicle's powertrain, braking, or suspension systems should be reported to your insurance provider. We recommend consulting local laws, regulations, and your specific insurance policy terms.
We specify the compatible models and years on the product page. Please verify carefully when placing your order. If you have any questions, please contact us.
Our design philosophy is "enhance, not replace." Taking the magnetic lock as an example, it is fully compatible with all unlock commands from the car's touchscreen, mobile app, and physical buttons. It only provides assistance during the closing phase and does not interfere with the original signals.
You can first review the installation video or documentation we provide. If you feel confident, you can proceed with the installation using our guide. If you determine it is beyond your capability, it is best to have it installed by a professional repair shop.
