Speed hunting in cruise control

[Stephen L]

Hi guys new here but I'm currently running into a problem in my 2015 all terrain. I was driving home and it seems like the v8 v4 mode keeps coming on and off. I noticed it more so while in cruise. It just doesnt seem to hold speed. Seems like it constantly trying to find the set speed. I have no codes as of right now. Truck drives fine shifts fine in both manual and just regular driving. I found it really bad at 95 km/h.

Is it stock?

Mine does the same. Just cant hold speed on hills. Sad but I keep my foot on the gas when going up inclines. 

 

Been wondering if there's a tsb for this.

Mine seems to do it all the time now. At 95km itll drop off the pick up then drop off and pick up. Had to come out of cruise but I noticed it did it occasionally while driving. It's like the throttle pedal just became way too sensitive

Mine started doing this after the lift. I assume due to the 35s and stock gears. I did a speedo correction and I think it's fixed it

The V4 mode switches on when it thinks that it doesn't need full power. Going up and down hills, along with simple changes in the terrain can make this happen. Not sure how to fix it. Same with my 2018 GMC Sierra SLT

An easy fix is getting a range AFM delete module. This will lock it in v8 mode all the time.
