Both my dashboard and infotainment screen suddenly went dark while I was driving on a highway. After about 30 seconds it began to reboot and came back on. I looked it up and I see this is a known issue and they advised to hold the volume button down to reboot the systems. It happened again while I was stopped at a light and I did that, and it came back on. Why is this happening? This is really not acceptable with a new car and frankly makes me nervous about what other things might start going wrong. Any advice?
