This has happened several times now. 30 min drive to work. 11 hr work day. Start the truck remotely, walk the 50 ft to it. I get in the display says powering down. I press start and screen is black. Radio works on last station. Can't answer a call because no button on black screen. Drive 30 mins home. Alls fine the next morning, but black again after work.

 

This may be due to unstable voltage. This has happened to my car before, but I cannot repair it myself. I still went to the repair shop to have my car repaired

 

That sounds like a weak battery. Many have had battery issues on the new models

 

I would try to get it on video so you can show you can show your dealer, but as others said it sounds like a crap battery
