    2022-2023 Denali issues?

    Mine also has the no heat in the back issue, but I live in NM so it's not that big of a deal. If it's cold I just turn the rear climate off and heat from the front. Not ideal but it works for the time being. Through the research I've done it seems the rear heater coil gets air in the line which...

    2022-2023 Denali issues?

    I have an 22 AT4 XL 6.2 (although they're not called "XL's" any longer). I have been extremely happy with the power, towing, smooth ride (magnetic suspension), space, etc. It does everything I need and does so with ease. The recall scared me but I took it in and it passed the test so now I have...

    How to search Dealer Inventory for Second Row Bench?

    I needed a 2nd row bench, ended up with a 22' AT4. When I was looking at dealers all across the country I literally had to look at the online pictures to confirm for 2nd row bench because you can't trust the specs the dealers put online.

    BREAKING: GM is officially recalling the L87

    FYI, took my 2022 Yukon AT4 (XL) to get the pico test yesterday. Took them all day but apparently my engine passed the pico test (60k ish miles). They changed the oil to 0W40 and my warranty now goes to 150k miles. Was kind of hoping for a new engine but I'll take the warranty.

    Power side steps in snow

    I have a 22 AT4 and live on a dirt road that gets extremely muddy when it rains or snows. There have been a few times where the side steps wouldn't go up and just kept going up and back down. The problem is the hinge is directly in line with the tires and they get caked even when stowed. Unless...

    AT4 versus Denali

    I have a 22 AT4 (XL, though I know they don't label it that anymore) with the second row bench seat and the 6.2L. The magnaride suspension is awesome! I didn't get the air suspension because I'm not gonna take an 85k vehicle anywhere I may need an extra inch or two of clearance. When I was in...

    Power steps on '22 malfunctioning

    I have a 22 Yukon AT4 and live on a dirt road. When it rains the road gets really muddy and all that mud gets all over the retractable steps. I have once experienced the same thing that you described so when I got home I washed the mud off the steps, specifically the actuators, and it fixed the...

    Loaded AT4 vs base Denali

    I have a 22 AT4 XL, only thing I don't have is the air suspension. Don't know if it's a chip thing, but I have memory seats... Don't know if you ever plan to go offroad at all (not that I do, just camping but def not doing anything crazy that I'd do in my old Tacoma), but last year I was camping...

    Trans Temp

    Towed my 5,500 camper this weekend for the first time with my 22 Yukon AT4 XL. Did great, I live in NM so it’s nothing but hills and mountain towing. Highest my trans temp got was 190, mostly stayed around 173. 190 is still well within limits so tow on my friend!

    Engine Opinions

    Just towed our 5,500lb camper this weekend with our 22 Yukon AT4 XL with the 6.2 and max trailering package (first time towing with her). I was very pleased with the engine. We live in NM so I’m always towing through the mountains to get to a camping spot. My main concern is always transmission...

    AT4 second row bench.

    I have the second row bench but need it for my big family. I have also owned a suburban with captains chairs. Easier to access the third row with captains chairs, and definitely more desired to have the captains chairs these days. I hope it doesn’t take too long to fix but I’d send it back.

    2021 Tahoe Z71 disabled after software update

    Picked my Yukon up from the dealer this morning and everything is back to normal. They were able to do the software update via wired connection after about three tries and it finally was successful. Regarding the OTAU, lessons learned: do not attempt any update unless you're parked at home or...

    2021 Tahoe Z71 disabled after software update

    Mine is still at the dealership and it's been three days and they still haven't been able to get power to the vehicle. I got an update yesterday saying they couldn't do the software update manually. They are now having to "reprogram" the vehicles electrical modules because none of them are...

    2021 Tahoe Z71 disabled after software update

    Did you figure anything out? Same thing happened to my 2022 Yukon XL AT4 that I bought a week ago!! 7k miles on it, had to go out of state to get exactly what I wanted. My very pregnant wife was stranded with our other kids, no power to anything. Couldn't even lock the doors. Nobody would tow it...
