Running loaded or unloaded does not matter, problem just started never did this beforeHave you tried running in Tow/haul mode to see if it acts any different? Are you running unloaded (no trailer) when this happens or is it all the time?

How do you do that, just have one button to push, when I turn it on a yellow light lights up on dash never seen a green lightDid you inadvertently switch it to "auto" mode, instead of "full time"?
Auto is a green icon, and full-time is orange.

You push the button once for full and a second time for auto. With that said I am not sure about the 2011's? Maybe they didn't have that feature back then? It might just be one mode on those.

I was reading the other day of some other people having the same issues and they narrowed it down to the tune. I can’t seem to locate the link I saw it, but it said something about reverting back to stock Tune, then reloading your tune if I remember correctlyFull EGR delete, 5 Inch exhaust, GDP 5 stage programer
