Alternator/generator/regulator problems of the 2019 Kia Motor Sorento

On 3 separate occasions (2 of which occurred 3/1/20). After stopping my vehicle, I lost all electrical power when I attempted to restart. No displays, no lights and of course the vehicle wouldn't start. After exiting and entering the vehicle multiple times everything comes back on. The battery and alternator test fine and the keyfob battery is good, the vehicle was not in motion when the incidents occurred.

While driving on highway, radio on and only connected via bluetooth. The radio screen was flickering and then shut down as if I manually turned off . As this happened the dashboard lights and my headlights shut off. I had to safely pull over and by the time that I did, I couldn't record it for evidence as it rebooted itself. I called right away and had to wait 2 days for appt. This is the 3rd time and rick case kia in sunrise FL keeps giving me the run around. My battery and alternator is fine. I honestly think they stop caring and just give me excuses and tell me they have to wait for mfg decision on my issue. My issue seems to happen when I am driving and cannot be on my phone recording as they want some kind of video as proof . So disgusted with their service and wished I wouldnt have gone with a kia.
