Why would my auto headlights turn off intermittently in the dark?

What is your question?

I leave my headlights on automatic and several times when driving at night or very early morning my headlights have completed turned off and then turned back on a couple seconds later. Each time it was definitely dark and should not have turned off and was not driving through a highly illuminated area. Can not replicate the problem it just happens occasionally but it very concerning and dangerous. No warning lights or codes or anything has been found to cause this. Light sensor under windshield is also not blocked or dirty

How long has your 2017 Hyundai Elantra had this problem?
