Automatic headlights not working?

[Atlas]

A few nights ago, I took off in the truck at dusk. It wasn't dark out, but most vehicles had their headlights on, and a handful that didn't. Mine hadn't come on yet, so I just figured maybe it wasn't time yet.

 

But then I started seeing other GM trucks with their headlights on. And when I looked at my headlamp switch, the little orange LED was dark, and it was set in the "auto" position.

 

The switch functioned normally when I turned the headlights on, and the orange LED lit up in the headlamps on position, headlamps and running lamps all came on. The infotainment screen didn't dim, however.

 

I drove like that to my destination, didn't want to be turning headlamps on/off while I was driving. Got in it the next day, and "auto" was working fine again.

 

 

What the heck? Software bug? Headlamp module 2.0 didn't boot correctly? This truck is really starting to drive me crazy...it's like this stuff wasn't tested all the way before it was released!

While I don’t think I have had an issue with mine not coming on, they do come on later than I would like. Both my 09 and 12 came on what I thought was early, but the 20 seems real late. I may have had your issue as I have turned them on myself a time or two. 
 

What is so strange is they come on in my garage before I get halfway in.  
 

I agree there are way to many software issues going on.
