Today suddenly the Driver Information Center display on my 2017 Envision is totally blank. I drove the car this morning and it worked. The second time I used the car I noticed the display was blank. I turned the car off and restarted and still have a blank display. Wondering if there is any reset or control or is my only choice to contact the dealer?

An hour after posting this the DIC was working. Any information on intermittent issues would be helpful.

Most likely that your vehicle was performing an over-the-air software update. These events occur automatically between your vehicle and GM independent of the driver/owner and can be disconcerting if they happen while you are in the vehicle. I've had it happen and it shut down the center stack display and all related functions including the nav system for the duration of the update process.
