I just purchased a MY and noticed that sometimes my Bluetooth sync is turned off and sometimes it stays on. I haven't worked out the conditions that it changes though. I keep Bluetooth on all the time on my phone and never touch the settings in the car (unless I have to turn sync back on).
Maybe it turns off if the phone is out of touch with the car for too long (overnight). Maybe it just does it randomly. Maybe it does it every time I lock the car but I don't notice because I don't send text messages every time I drive.
Anyway, how do you report an issue like this? Being a new Tesla owner I'm still getting used to how things work.
