2021 GMC Acadia AT4 Dashboard Question

[Aces11]

Have a 2021 GMC Acaidia AT4. While driving the dashboard turns off and goes black, then restarts up. Vehicle seems to continues to drive normal. Any idea what would cause this? Wondering if it’s the alternator.

You may have a grounding problem.

That doesn’t sound like fun. Any place a guy can start to look? I am pretty handy, but no mechanic.
