Headlights problems of the 2016 Hyundai Genesis

While driving the other night, my headlights turned off on their own. The headlight setting was set to auto and they flickered twice before shutting all the way off. At this time I was on a dark road without streetlights. The only way to remedy immediately was to turn the headlight setting to on rather than auto. This also happened this morning as it was raining but I figured that was due to gloomy weather.

2300 started my car to go get lunch (at work). I first noticed that my lights were not on (they are set to automatic) so I turned it back one and they turned on; however, the headlights would not. Also no sound when using signals. Lastly, the seat belt chime woud alarm every 15 sec or so, the warning light on dash stayed on. After shutting off the car (went in store) and restarted it all seems to be good?.

Headlights are set in 'auto' mode, but erratically/sporadically with no rhyme or reason, they will shut off, then turn on. One time I was able to record the event on my phone (available is requested). But another time they turned off then on (like I was flashing my lights) while driving. Another car was trying to enter traffic and thought I was flashing him to enter, resulting with me hard-braking to avoid hitting the entering car. This 'flashing' of lights has happened on more than one occasion, but I can't duplicate on demand (which is why the Hyundai dealer is stating they can't do anything about it. This is a driving safety issue. This has happened on numerous occasions, but I indicated the latest below.

While driving 70 mph on a highway at night all the interior lighting, dash, and headlights went completely out for three seconds then came back on. We slowed down but this happened three times before we reached our destination. Took it to the dealer who was able to recreate the problem and repair the car.
