Q: Does this bushing kit affect my Tesla warranty?

Installing aftermarket suspension bushings does not automatically void your Tesla coverage. The Magnuson-Moss Warranty Act means Tesla has to prove the kit caused a specific failure before denying that claim, not simply cite the modification. Keeping your factory bushings gives you a route back to stock. The sealed spherical design is built for long-term reliability, so it is meant to live on the car for years, not fade after a season.
