Thanks yeah there are about 6 other trucks just at the dealership I bought mine from with the same issue

Wow yeah that's the same exact issue I'm having! All the dealer tells me is G.M is working on a update but there is no fix for it right now. Next time it happens I'm going to try and shut it off and turn it on pushing the 4wd button. Thanks I appreciate it. They told me to make sure the traction control is off then hold the button down to till it says ecs off also before using 4wd and I haven't had it happen since I been doing that but I'm not Convinced that's the issue

Thanks I appreciate it. Yeah I have taken it to the dealer 4 times now and everytime I get there and it goes away. After I told them I seen hundreds of people on line having the same exact issue and they have replaced everything and it still does it they said yes we have 6 other 2022 at4s with the same problem but there Nothing we can do, GM needs to do a update or something that's not available. They told me keep the traction control off and it should help. I told them I use this truck for work and spent $80k on it this is not acceptable they brought me in the sales managers office and said ok we can get the ball rolling on buying it back.. I already had plow, salter, lights put on it and most likely the new one will do it to if we take it that far..

Yes sir everytime

I have a 2022 GMC At4 and the sevrce 4wd comes on and the 4wd will not work, Also the parking brake comes on when this happens, After I shut the truck off for a few hrs it works again, There are no codes and the dealer says nothing they can do. Anyone have this issue fixed and what did they do to fix it?

I have a 2022 GMC At4 2500 and I use it for work and the service the 4wd light comes on and 4wd does not work. The parking brake is beginning applied when this happens, after letting the truck sit for a few hrs it goes away. I take it to the dealership and it always works well its there and there are no codes so nothing they can do. I have seen other posts about this but never seen anything fix this issue?
