I ran into my first Tesla malfunction just now. I left the car home today, but logged into the app to check on it. It was still at 51%, even though it should have been charged to 90% by 7:30 this morning. The app still said it was scheduled to charge at 7:30 this morning. Also, the update cycle didn't happen at the bottom of the app screen, even though all the data was showing as new. I tried resetting the app. I also noticed the Tesla Charger icon was missing, and it just showed a cord sticking out of the Tesla, leading to nowhere.
I tried to turn on climate control, just to see if I had control of the vehicle. The A/C turned on and temp began dropping, but when I tried to turn it off it failed to do so. I called my wife, and asked her to go to the garage. The car would not recognize her phone, so she had to go get her card. She called me and told me the screen was off and she could not get it to turn on. I got her to do soft reset. The screen returned and everything was functional again, except my wall charger icon is still missing from the app. The car is charging properly, but I wonder if all of this was caused by the software update.
