NHTSA Complaint #11546990 — 2015 HYUNDAI VELOSTER

My cars lights (headlights, gage cluster lights, dash lights, radio screen light, etc..) and screen for my radio and back up camera, all turn off by themselves, for maybe 1 second or 2, while driving. This happens randomly, no warning, no special conditions, just out of nowhere, and for no reasons. Since I bought the car in September of 2020 (used, as is) it has done it now 7 or 8 times, with tonight being the most recent occurrence. I don't know how to have it checked or verified by a technician because there's no forewarning before it happens. It's completely random and unexpected. It's very scary, especially with my children in the car.
