Yes, the Coil SumoSprings Custom Helper Springs # CSS-1145R are confirmed to fit your 2023 Toyota Highlander Limited Platinum. You should not have any issues for your warranty as it is a add on part and you are not modifying the vehicle components. You are simply helping to provide support to the rear coil springs. The only way you would void your warranty is if Toyota could prove the parts caused a failure or you tried to overload the capacities given from Toyota.
