I have a 2022 Tahoe and the headlights are on about 90% of the time even when the selector is set to auto. Bright sun and they are on- interior gauge lights and infotainment brightness functioning normally. Anyone one else having this issue? suggestions?

Same exact issue here on a 2022 Tahoe Z71. Took it to the dealer and they stated they couldn’t find anything wrong. Yet, all the 2021/2022 Yukons, Yukons XL, Suburbans and Tahoes I see on the road only have the running lights on during the day.

Yes apparently this is a bit of a known issue. The headlights are not supposed to be on- only the DRLs during the day. I took mine to the dealer and they also said they could find no problem, but luckily one of the techs was sharp and they took the car outside for testing. Then they found the issue- which was something called an ambient light sensor. This problem cannot be found by trying to diagnose the vehicle inside the bay it seems. Good luck, let me know if this helps.

Here is my ticket which did fix the problem:

I just had it replaced and picked up today. The same part you listed above was what was used on mine. The headlights still come on during the day. They pulled around a brand new Yukon Xl Denali and it did the same thing. Just to be sure they had a Yukon AT4 that was new as well and it’s headlights were on during the day.
Did something change on a late 2022 build with headlight DRLs?

Hi- very strange. I can tell you that I own a 22 tahoe, my wife owns a 22 tahoe and my neighbor just bought a 22 yukon XL and none of these headlights are on in daytime. When I brought mine into the dealer for repair on the headlights they acknowledged right away that it was not supposed to do that and they fixed it while I waited. You do not have to take your vehicle for warranty work to the same dealer you bought it from. Maybe there is another dealer close to you that can look at it. But its my understanding the headlights should not be on during the day.

Apparently there is a bulletin out for it and I am going back on Tuesday to have it performed. I will update after this.
