Question about the Headlights

[R32driver]

The only time my DRL are on is when the vehicle is driving in a shaded area. If it is sunny, the headlights are on instead of the DRL.

Pretty sure that's the opposite of how the headlights are supposed to work. Our DRL is always on and never the headlights during the day unless it's really dark cloudy/rainy weather. On a sunny day the headlights are off and when I enter the garage they come on, or vise versa they are on when I start the car and as soon as I back out of the garage the headlights go off and it's DRL only. Kind of the whole point of a having a DRL that is separate from the actual headlights

That’s how mine work too, I can’t do a test with the sun, been so crappy in michigan the last 2 weeks we havnt seen the sun LOL

I wonder if this is the same sensor that is in the 21s, as I still think it could be software since this seems to be fairly common and, so far, looks to be in the 22s not the 21s and if we have a wide range of build dates, then GM didn't just get a bad batch of sensors at one time. Just to settle some curiosity. Those who are having the issue, what make, year and build date do you have?

Me: 2022 Tahoe RST - Built the week of March 7, 2022.

Interesting, no issues on my 21 RST. Only thing noticed constantly turn on in minor overpass when sunny. I guess thats how it should work…

Looks like the theme is 2022s built in late Feb to early March so far. So it could just be a bad batch of sensors that were delivered to the factory rather than a software issue.

Right, that’s what the service dept told me: the sensor has an error code, and needs replacing. Didn’t seem it was a software issue.

Same issue on my 22 Suburban that I just picked up.

 

[deckhand]

Just figured out that if I cover the sensor with my hand during the day (i.e. Dark), the headlights turn off/ DRL turn on. When I uncover it (Full Sunlight), the headlights turn on. But at night; the headlights do automatically come on… weird.

Do you know what error code was reported?

I made an appointment for this but I won't be able to get it in until 4/22... let us know if they get it fixed and working right!

My 30 day old Yukon SLT is doing the same thing, drl lights are on in normal daylight (early am) and as soon as there is bright sunlight the headlights come on. Nobody at GM seems to know what is going on!

 

[Crzylgs]

I just got the ambient light sensor replaced and that seemed to be the fix. The DRL now turns on when it is supposed to as do the headlights.

Can you share the replacement part number please?
Thanks

My 2022 YUkon XL Denali was doing the same thing . I took it to the dealer and they found code B108E diag. They replaced the sensor and so far it has been working as it should.

Definitely the sensor, today I placed some amber transparent tape I had over the sensor (took about 15 pieces) and now the lights work as they should, DRL's on in bright sun and shade, headlights come on a bit quicker going into dark garage but that is to be expected with all the tape shading the sensor. My dealer has ordered the new sensor so hopefully it will be one that works.

Did you get a follow up on this? I’m about to send mine in. It definitely seems strange so many have this issue.
