I have a LR RWD (vin 58xxx) with 2019.5.15 firmware. On Feb. 13th, I was getting 308 miles of range at 100% charge. Over the course of the next 3 days, my range at 100% charge has dropped to ~298 miles.
Here are the 4 charges I did over that period (to 80%, projected to 100%) along with the displayed rated range at the completion of the charge:
The ~20 charges I have done since then have all been consistently around 298 miles (projected based on an 80% charge). I tried discharging to ~20% followed by a charge to 100%, three times, as recommended by Tesla to 'recalibrate the BMS'. In both cases, the max was still at 298 miles:
3/3 charged from 19% to 100%, added 242 miles; 242/0.81 = 299 miles
3/7 charged from 23% to 100%, added 230 miles; 230/0.77 = 299 miles
The 2019.5.15 firmware update did not change my numbers at all. I'm concerned that I may have a bad cell in the pack?
