Headlights/taillights randomly turning off/on.

I have a 2015 Genesis with only 17K miles. I generally drive it at night once a week for a 20 mile round trip. Most but not all of the time my headlights (and maybe all exterior lights) shut off and then come right back on once during the trip. There seems to be no consistancy as to when it happens, other than they have been on for at least 3 minutes before it happens. It has done it while driving as well as while stopped for a traffic light. It has done it with the auto hi beam accessory off and on.
Anyone else have this problem or aware of what would cause this?

There was a previous thread where a short in the stalk was the culprit. Also, a few have suffered similar infrequent events (like myself), that seem to come from bright exterior lighting near the road that causes the computer to have a momentary brain cramp and the lights go off for a second or two before coming back on.

Thank you so much. That is great information.

It'll be a loose connection in the stalk. Mine does this as well, I just remember to switch to On instead of Auto and it won't happen. If you have the instrument cluster set to show lighting states you'll see it rapidly flash between Auto and Off when the lights go out and lightly brushing the stalk can aggravate the issue when it happens.

Is this option on the '18 G80 Sport?

That's exactly what happens when the lights flash on and off. I generally leave the headlight switch in the AUTO position.
One thing I regularly do/did is this: Whenever I pull into my garage or park anywhere with my headlights on, I have been turning the switch from Auto to On and back to Auto so that the headlights turn off and don't continue to run on the delay feature. I'm thinking this might be good for the battery. However, lately I have been turning the switch from Auto to the parking lamp setting and then back. Since I've been doing this I have had no more problems with my headlamps flashing on and off. Coincidence? Time will tell.

Old news, put I did have the turn signal stalk replaced under warranty and have not had any problems since. Glad I had the warranty as this was a $700+ repair.
