My indicated range for SOC 90% has dropped from 279mi when it was new (12/18) to about 262 mi. Car has 7300 mi and has software 2019.36.2.4. I started noticing the drop slowly since May. I have never supercharged since we have no supercharges in Honolulu and the entire state of Hawaii). I only charged 100% maybe 3 times and only charge up to 90%. Should I be concerned? SC said it was ok and that the car will eventually calibrate itself. Has this happened to anyone?
