My wife has a 13' Escalade with the same powertrain but no such issues

Got the Yukon back from the dealer without any changes they said its normal and nothing to worry about it. And its on life time warranty if something happen we are going to do the need full.

It might be cause it's coming in and out of 4cyl mode. Easy way to test the theory, you can have the AFM readout on the DIC whilst you're driving and see it the two coincide.

This. And that sucks because the switch from 4 to 8 only gets worse. Then it will start vibrating eventually. Verrrrry annoying. My hoe right now is my first GM SUV (5 of them since 07) that it isn't horribly noticeable. But I have major transmission issues...

My truck does this as does my dads 2012 tahoe.. Its not really noticeable unless you're really trying to feel for it but its visible while looking at the tach like in your video. I honestly just started noticing it in my truck but then I drove my dads 2012 and watched it do the same thing. Im going to say its normal.
