Dash going black

Hi, I'm one of the auto experts on RepairPal's Car Genius team! Sorry to hear you are having issues with your Cadillac XT5. The dash intermittently going black like that and then reloading sounds like a connection or software issue. Seeing as it is such a new vehicle, there is a good chance that this is something that would be covered under your manufacturers warranty. I’d strongly recommend bringing it in to them to diagnose and potentially repair under warranty. If you need any further advice or would like help finding a trusted RepairPal shop in your area or even getting an appointment booked, please feel free to call us at 877-913-1554 or check out https://repairpal.com/certified
