I see on TezLab that the top ODO guys have up to 138K miles, my 55K miles on my Mar. 2018 TM3 doesn't even get me into the top 50 on the leaderboard, though I am close. I have had great luck with my car and Love Love Love driving it. Retired, so I do Supercharger Hunting to give me a place to go.
I did do the 100% charge this week for a road trip and discovered that it only made it to 303 miles. Not a BIG deal as I was only ever seeing 310 on a full charge. It helped that I rarely charged to 100%. I drove it to zero and charged back to 100% just to be sure and it made it to 306. Not too different from the best I ever saw. Perhaps I can just relax now that I have been thru the early degradation. Shame that the update that took the early TM3s to 325 miles range didn't do anything but take me BACK to 310 miles.
FYI I recently learned there is a trick to the “drive until almost empty then charge to 100%” deal to try to retrain the battery. Apparently the BMS needs to “rest” after each step in order to actually learn where zero and full are. I was told run to near empty (10% is fine) then let it rest for a few hours, then charge to full (90% is fine) and let it rest for a few hours. Rest means no sentry mode, no nothing. Let’s the car go to sleep and allows the BMS to mark the voltage and learn the top and bottom of the battery. This was from a Tesla Ranger guy who really seems to know his stuff.
