After a week of weird blips and pops My car notified me to connect to WiFi to download an update. My car is on 2020.16.2.1. So I tried connecting to WiFi, which was different since my car has been on my home WiFi for over a year.
The car could not find my WiFi network. Of course the Tesla app could not connect to the car because the car could not connect to the WiFi. Good one! So after some messing around trying to reboot, unplugging the charger and cursing, the car came on, found my WiFi And has downloaded 2020.16.3 And is installing, Which I thought was done a couple of weeks ago? But I am old and could be a senior moment.
Still the most fun car I have ever driven in my over 50 years of driving.
