I own a 2016 signature model X P90D with 23k miles on it. The battery has lost its 80% range from 229 miles to 191miles at the last supercharger event. I have called Tesla to ask if this is an acceptable drop in range or if we need to check for issues. Have not gotten a response at this time.
With all the promising news about new technologies, to include dry cells, superconductors, and even in the distant future, the potential of a graphine cell system, I don’t know if I should wait, or push for the current technology to restore range. Will we be able to retrofit our current batteries with these new systems?
I can’t get a straight answer to these questions from anyone at Tesla.
