Wife's 2018 NX just started having some sort of weird issue. I think this started about a month or so ago and she said her lights would flick on/off at times. Figuring it was the battery since it was 7 years old I swapped that out for a new one.

Then the last couple weeks my wife tells me that when the headlights are in the Auto position at night when they turn on, after a short time they will flicker on/off,..etc. When you turn them to the ON they no longer turn on/off...etc. They stay on the entire time,

Process of deduction tells me that this would indicate the light sensor on the top of the dash is either faulty or going bad but I've never seen/heard this before...

Has anyone experienced this with their headlights?

I've adjusted the sentivity of the headlight sensor and that has no affect at all. It can be pitch black outside and they will come on, then you can hear them click off and click on again shortly after.

Tonight when I drove the car. The stalk was in Auto, it got dark, lights turned on fine. Then 10 minutes into driving they turned off/on.... wait 20 seconds then off/on... I put the stalk to the on mode for the lights and they didn't do that again for the rest of the 40 minute drive.

*To clarify this is NOT auto high beams. This is just the stalk is in AUTO, and when it gets dark the headlights turn on... then they turn off, turn back on... turn off turn back on.,..etc. Can happen a couple times as soon as they turn on. Then won't happen for a few minutes. Almost like if someone was manually turning the stalk on and off quickly.

Thanks much,

This is a very interesting dilemma, so I copied and pasted your whole text and below came up — see first pic.

Sounds like you thought of every possible option to help resolve the issue.

I noticed at bottom of first pic a link (circled in yellow) and clicked on that and saw the yellow highlighted portion at bottom of second pic that also advises same as first pic.

Hopefully, someone will chime in that has or had same issue and how it was resolved or you’re able to resolve on your own.

Either way, please update this post on what happens / happened next and if you were able to fix the issue.
