I've got a '21 AT4, seats are not very comfortable. Definitely not as nice as my '11 LTZ, my '10 SLE, or my '04 LT. I had a '23 LT for a bit (heated, but not ventilated seats) that was much more comfortable than the AT4... I wonder if the ventilated seats reduce the cushioning?

Is this the "right" red to match the AT4 / Trail Boss tow hooks?!

Just discovered today that my local GM dealer won't install undersized winter tires on my AT4 (came stock with 20s and my winters from my '11 Silverado are 265 65R18) - and they refuse to recalibrate the speedometer to the smaller tires. I couldn't find any Nokians to match the 20" AT4 tire size (265 60R20) - it looked like they top out at 19"... what size are you running?

Would love to know where this is!

My 2010 and 2011s did this too! Must be a well hidden / poorly advertised feature!

This one works with my 2021 AT4 - the top part of the tailgate won't release while this is closed, but the whole gate will. There is no hard lock on the outside of the tonneau cover, but it can only be released after the gate is lowered. https://www.actiontrucks.com/product-detail/ACTENT114/enthuze-soft-tri-fold-tonneau-cover

I've got the same issue on my 2021 AT4, I've had it for six weeks. Noticed it about three weeks into owning it (brand new). Sales guy says it's under warranty so I'll need to take it in. Interesting that it's the DRL setting only - when I turn my headlights ON or am driving at night, I don't see the colour difference. It is also not apparent when I autostart the truck and stand outside it with the perimeter lighting is on. I would never have noticed it if not for this forum sparking my mind to check - so thanks!

Mine fit fine - I don't notice this gap at all.

Hey folks: Just traded in my '11 LTZ Z71 and am now the happy owner of a new 2021 AT4 here - pic below! I can't seem to figure out how to get my mirrors to tilt down when I throw the truck in reverse... this was probably one of my favourite features on my old truck. I searched this forum and others and can't seem to find ANYTHING on this - did GM delete this functionality or am I just missing a setting somewhere? Thanks in advance!
