I am new to the Tesla forum family. Please don't hang me out to dry if this topic has already been discussed as I cannot seem to find a search option and the forum. I have a 2016 facelift model S that was manufactured on November 26 of 2016.I have concerns over the range of the car. Right now I have 55000 miles and at a 95% charge it saying I am only rated to 256 miles. I know when new the car should have been rated somewhere just over 300 miles range. So my question is should I be concerned about the life of my battery and/or is it failing?
