Yesterday, Saturday November 17th, 2018, was my first day driving my New 2019 Sierra 1500 AT4. After driving for the first couple of hours, I started noticing that randomly at different times, the Driver Information System Screen would go black / blank. The screen stays blank for about 7 to 8 Seconds , then comes back. In a 6 minute 13 second monitoring by me while driving, the screen went blank at minute 2:04, then at minute 2:45 and again at minute 3:06.
Does anybody know why this is happening?
