Made an appointment with service today, They said it is normal to do this. Something to do with the active fuel management on the v8. But I have a v6 in base model when I told him this he was kind of dumbfounded as he didn't think my truck had the cylinder deactivation. We will see what they have to say when I bring it in thursday

I'm having similar problems, I have a 2014 double cab 4x4 v6 sierra. I'm having a problem where the truck shakes at low Rpms in what feels to be high gear (around 45mp, it feels like the truck is struggling as if you were driving a standard car at very slow speed and in top gear). I also noticed that going down hill my tach bounces up and down about 500rpm.
