This is in a 2017 XT5 Luxury. Around two days ago, while on a trip, the LCD information screen (the one where you have three choices of displays actuated by the direction buttons on the right portion of the steering wheel) began flashing on & off on a random basis. At times, the screen remains blank for a while, then it illuminates again, only to go blank in 10-15 seconds. Contacted local dealer who sounded like a deer-in-the-headlights as to what is the matter. Told me to bring it in when "it's doing it." Now, seriously, how can something which is so randomly intermittent be predicted to "not work?" I pounded the top of the instrument cluster shield, the bottom, the plastic shield, and nothing ( in the way of vibration) causes it to actuate. Neither does the angle of the car (up or down a hill). Going over bumps has no effect on it. The lighting affecting the tach, speedometer, fuel, etc gauges is not affected.

Next time it does it, take video with your phone. Then, take the car to the dealer, show them the video, and tell them you will be driving their loaner car until they can duplicate and correct the problem.

Even if they can’t duplicate, sometimes things like this will set trouble codes and lead the service tech in the right direction for a repair.
If you haven’t already brought it into service, then I’d suggest you do and have the techs look at it. Hopefully they’ll find a trouble code, test a few things, wiggle some wires, and come up with a repair.

Love this!

RESOLUTION: After attempting a software approach with help from the GM techs, the dealer finally decided it was the actual screen which was defective and an entirely new gauge cluster was installed. The problem has been fixed. Hopefully if it happens to your XT5, it will be within the warranty period!
