My wife has been driving my Model X this week while her car was in the shop. On Wednesday while she was driving home with the kids, the car started changing music stations, turning the A/C on & off, turning heated seats on & off and honked the horn. Since I was at home at the time, the kids thought I was using the App to play a joke on them...but obviously not. As soon as they got home I did a reboot of both screens to be safe. I do not use any public WiFi - only home and work that are PW protected. The X has AP2 running 2018.12 firmware. Any thoughts?
