How many miles on the truck?

You may have a unicorn! Wondering if anyone else with an AT4 has Sport mode.

So odd. I have a call into my dealer with the question

I have 13k miles. Ordered it January and took delivery in May.

 

[slythetove]

I'm just over 3k miles at this point.

 

[BB2022]

Less than 2k

it's the tires and their speed rating. if you have the AT tires, you have sport mode (mine has sport mode). If you have the MTs, you do not.

What does "off road" mode do when it's on?

 

[Dlymburner]

I have the 3.0L refresh and it also has Normal, sport and offroad. 20" wheels as well.

So can Sport mode be turned back on if your truck does not currently have it?

Good question

Good question

so that is a big NO upon further research it is the mud terrain tires if equipped cancels out the sport mode and the trucks that have it grayed out that was a mistake from the factory and has a service bulletin for an update to remove it

How do you get non-MT tires? They came standard on the 20" wheels and I'm assuming on the 18s even more so. Was there some option where you could actually choose an AT tire?

 

[Denalibq]

yes if you build a sierra you can pick AT or MT with the 20" wheels and the 18" is only MT. so i supposes it is how your truck was ordered from the dealer
