Driving mode possible issue

IBMC 92 · Dec 7, 2021

I believe it is a chip issue and not a tire issue. Another option removed because of the chip shortage. Kind of the reason I jumped on a 2021 that has all the options. They keep deleting options. Hopefully like some of the other ones it can be corrected at the end of next year when they expect the chip shortage to be not such an issue.

Just got this from another source.

Well that makes sense why I can’t select it, I have those tires on mine. Thanks for calling and pulling the tsb!

Hey guys new to group and AT4. I just purchased a 22’ AT4 limited and noticed when selecting different driving modes, it will not let me select sport mode it scrolls right past it. I guess I’m wondering if this is normal or should the truck be brought back to dealer to have it corrected. The salesman said it was normal but hardly believe everything they say. Thanks for the input.

Salesmen are like politicians

Please keep me updated if it starts working.

I know the tsb was provided, but I hit 500 miles on Thursday and still no sport mode. Just wanted to provide an update.

Im only at 200 miles with my 22 limited at4 6.2, when I hit 500 miles i'll also reply and let people know whether sport mode is turned on. Highly doubt it based on the TSB.

Mine worked immediately- 6 miles on the OD!

What's the RPO code? I've got 2022 Limited AT4 and also it skips over the Sport Mode. Currently at <400miles, so I'll check back at 500.

Mine didn't change after 500 miles, currently at 900 miles. I think that's an internet rumor about a possible change to sport mode after 500 miles

. I just drive in tow haul all the time now, def more sporty

I used to have a Duramax with Allison transmission and that tow haul - down shifting was more aggressive too much downshifting for everyday driving but the tow haul on these gas motors is nothing like that!!

My 2 day old 6.2 21' with duractracs has it and it works. I had a rough day yesterday and responded to 3 stemis throughout the day. Basically gives me an excuse to haul a$$ though and sport mode in 2wd with duratracs is probably a bad idea lol. I was very impressed with the performance. Idk if its bad for it but i put it in auto 4wd and it really improved the traction on wet roads. Probably not the best idea with a hundred miles on it but it got thurough break in yesterday.

Not sure about driving it on hard pavement in 4wd @ hwy speeds but I’m with you on breaking them in like you normally drive!

Wonder if it's a programmable mode that can be unlocked. We got any tech gurus that can get into the module that controls that?

Let us know what happens. I've got the same model as you. Probably like others have stated, it's a lack of chip issue. Maybe even just pushing out the trucks.
