So just checking in to see since its been about a month.
Still no vibrations from 70-80?
Still no low speed booming over rough roads?
Still no buffeting at 69-72 on the Highway?
Just want to make sure since many of us bought 2016s without the issues and they developed over time.
My dealer unable to resolve the vibration, and GM engineers won't let them fix anything else, so they a working with Customer Service for a trade assist to a 2017.
We would get the same model as you, Denali XL in grey with the 20's this time. Not the 22s like my 201y has.
I just crossed 1,000 miles this morning and so far I have not experienced any vibration or buffeting at any speed or road condition.
I've tested it several times on the highway up to 90 mph and everything was good. No vibration in V8 or V4 mode.
I'm also not experiencing any buffeting at low speeds either.
Only issue so far is an annoying rattle in the second row DVD flip down screen that has developed. I checked the four bolts holding the unit into place and all were tight. Must be something internal that I'll have the dealership check out.
Other than that small issue, I love my new car!
Deuce16GMC, good luck with the issues your having with your vehicle. Hopefully GM comes through for you and gets you into a new car without any of the issues you have been experiencing!
