Headlight Switch problems of the 2012 Hyundai Genesis

When the headlight switch is in the on position, as opposed to auto, the headlights may occasionally flicker. This problem is exacerbated by using the turn signals. Sometimes the headlights turn off completely when the turn signal is activated and I have to move the turn signal stalk until the lights come back on. Again, this doesn't happen when the headlights are in auto. It's mostly noticeable in the rain when the headlights don't come on automatically and I have to turn them on manually. I first noticed the issue in 2015 when the vehicle was about 3 years old.

The headlights randomly turn off when the headlight switch is in the "on" position. This problem has occurred when the car is in motion at various speeds from residential street to freeway, while turning or going straight as well as when it is stationary. After the problem has occurred, touching or moving the turn signal stalk will usually cause the headlights to come back on. The problem has never occurred when the switch is in the "auto" position. The problem has occurred many times but is hard to replicate on demand. It is happening with more frequency now. The Hyundai dealer will not fix the problem because they can not duplicate it on demand.

Hyundai Genesis sedan w/tech package. While driving down a poorly lit road at approximately 50 mph, I activated my right turn blinker to turn right at an upcoming intersection. As soon as I selected the turn signal, both headlights went out for a period of 1 - 2 seconds, then came back on. Since the road was dark, I was literally driving blind and could have ended in a very serious accident. There has apparently been a few Genesis sedans reporting this same issue, but this was the first time this has happened to me. When I got home, I noticed that my headlight switch was in the on position. There is also the auto position. When in on, I could duplicate the issue randomly by selecting the turn signals, thought it wasn't consistent. When in auto, I could not duplicate the problem.
