Last night my car updated to software version 2020.40.4. Today while driving on the highway, I attempted to bring up the trip graph and the screen decided to reboot. Luckily enough I was testing my Sony ZV-1 and caught it on video.
I just recently hit 35k miles on the odometer of my Model 3. I do have my second trip meter locked in for the Lifetime power usage of the car, and this is where most other people will pull the number from, multiply it by how cheap their home charging kWh price is, take nothing else into account and give a rough electricity cost. That doesn’t give the entire story though.
This past Saturday, October 26th, 2019 was Tesla Fest East at NCCAR hosted by Out of Spec Motoring. Many Model 3 owners showed up to take their car on the track and experience what the car can really do, as well as a handful of Model S and Model X vehicles.
Owners came from locations far and wide including California, Chicago, New Hampshire and Florida to join in on the festivities. Track mode claimed many many tires lives that day. Many amps as well.
With the wider release of the 2019.24.4 firmware update, Tesla seems to have changed how leaving your car plugged in behaves.
In my very limited 2 days of observation so far, the new 2019.24.4 behavior keeps the car at your desired charge limit even hours after charging completes. To achieve this, more functions seem to run off wall power, one such being the cabin overheat protection.
