Lately I've been having a consistent problem whenever it's cold out. Upon entering the car, the center screen doesn't turn on, nor does the HVAC or radio, thus I'm assuming some form of the central computer isn't activating. The screen above the steering wheel is active and I can drive the (chilly) car. However, the screen above the steering wheel has a display that reads "battery heating, power will increase while driving." After about 10-15 minutes of driving I can reboot and the 17" screen/hvac/radio will come on. This problem persists even though I've de-activated sleep mode. When the car goes into this deep cold hibernation it also doesn't react to the mobile app, so it's not like I can pre-heat it to avoid the problem. This is really inconvenient and scary. Has anyone had a similar problem? I reported it to the service center and sent the car in for a checkup and they said everything was fine. Yet I'm still getting this problem whenever the car is outside in sub-freezing temperatures for more than a few hours.
