I had the dealership run the VIN number and they said the truck was built without sport mode. He said he confirmed it with the service department. They told him that since the truck was manufactured that way that they could not override the current configuration and reprogram the computer to have it. He said someone may have an aftermarket tuner than can. Either way its really not that big of a deal as I never use the sport mode in our caddilac. It was must more of a nerd question than anything. I would guess that whoever said they are cutting standard options and raising prices in 2022 is correct. Although I cant image that it would cost GMC that much more to program with sport mode than without. Probably somehow related to increased warranty work. Maybe push rod problem??? Thanks for the replies!

Yes, that is correct. Only normal and off-road. Sport is not an option. Here's the link that I referenced where there is a hyperlink by sport mode that indicates sport mode is not available on models with mud/all terrain tires. Scroll down the page a bit to where it addresses drive modes. Click the red hyperlink. Capability Features | 2022 GMC Sierra 1500 | Pickup Truck https://www.gmc.com/trucks/sierra/1500/capability

Jim, I do have a two speed transfer case. 6.2 engine. I've looked at other stickers of new AT4s and nowhere on there does it specify whether it is or isn't equipped with sport drive mode. Best I can tell all of the trucks are supposed to be equipped with it. Mickey, yes just normal and off-road mode when turning the dial clockwise to the right. Turning it to the left or counterclockwise is tow haul mode. I can see why GM might recommend not using sport mode if you have oversized aggressive mud tires, but I can't see why they would disable sport mode for it. I called the service center at the local GM dealership and they said they would not be allowed to change the configuration even if I had street tires on it. I'm just trying to find out if this is the case with all AT4 trucks or if there is some manufacturer error with mine. Thanks for the replies.

Hello, I'm new to the forum. I can't seem to find an answer to this question and neither the dealership, service, or parts has an answer. I just purchased a 2022 Sierra limited 1500 AT4. According to the owners manual there should be four drive modes. Tow/Haul, Tour mode, Sport Mode, & Off Road. The Sport mode is absent on my truck. I most likely will not have a use for the Sport mode, but am curious why it is not equipped with it. From everything I read in the owners manual and online marketing, it should be an option for this model. There is a *asterisk beside the Sport Mode description that is hyperlinked on GMC's help page that when clicked says this feature is not available with off road mud terrain tires. Although my truck is equipped with off road tires, it was not indicated as an option on the sticker. It is on most other AT4 trucks stickers that I have viewed. With that said, what if a person wanted to swap to a street grade tire and use sport mode? Thanks for any clarification!
