Q: Does fitting Stage 2 affect my Tesla warranty?

Installing these brakes will not by itself void your factory warranty. The Magnuson-Moss Warranty Act requires Tesla to show that an aftermarket part caused a specific failure before refusing a claim on that system. These kits are engineered to work with the Model S, and having them fitted by our Hawthorne technicians or an authorized installer keeps the install clean. Retain your OEM brakes so a return to stock stays an option.
