I don't have any buffeting or vibrations with my '15 Denali. It's a pleasure to drive at any speeds. I luv this truck.

Also, some people are more sensitive; others don't notice.
I remember when we started this booming in June 2014, it was a guy from Niagara Falls, NY the dealer swap 2- 2015 Tahoe and he end it going back to 2014 Denali, he start all this thing and I tell him I don't notice anything and always ask my family and they never feel or noticed anything.

That’s booming. Some don’t notice that.

The Chevy shake can’t be ignored.

Looks like his camera hand is shaking. Maybe he has Parkinson’s.

Have a 2015i Denali and have had no issues with vibrations and buffeting. Am not pleased with the short following distance in the "far" setting with ACC - it should be longer. Other than that the ACC performs as advertised. Also find with an 8 speed tranny and engine switching from 4 to 8 cylinders and back, there is often a lot going on in around town driving. I've gotten used to all this activity. No other complaints. Great truck.

GM transmission programming is set to always seek about 1500 RPM. You might try driving around in "trailer mode", I found it much better. Recently I've also converted to doing almost all of my driving in manual mode.

Yeah. That’s what’s causing the coffee and the keys to rattle uncontrollably.

I programmed mine with Edge CS2. Been running on level 3 with the AFM turned off

Get the same mpg, and the Trans is wonderful. How Chevy should have delivered

I want to try this, I know already tow mode is super fun when you have the touring exhaust from Borla.
