Has GM fixed the buffeting and vibration issues?

I believe 4x2 models are included as well. I know a rental I had in arizona last year (2016 model) was 2wd and it had the buffeting problem similar to my '15 4x4.

No difference, the roof buffeting is a vibration which is being caused by another independent tone. Proven by ear plugs in ear plugs out. Before my roof was re-glued the sensation was back and forth pressure in my ears like a single rear window being open on the highway ( and you can not close the window) Ear plugs had no effect in Lessing the vibrations. Then once the roof was glued and unable to “oil canning” dealers words not mine, just the pressure was present....worst over uneven pavement and at lower speeds 5-12 mph. Then again at 45 and 74 mph area’s. It was like someone was pinching your eardrums. Ear plugs helped to remove that tone. That’s how I had to drive my truck until they took it back. I believe the tone is in the rear drive line, either ring and pinion, pinion angle in drive shaft or anonther ghost. They told me they will continue to fix it, and then put it out for sale once resolved. So now I’m driving the 18 Traverse and getting my balls broke by my buddies. But to be honest, I like it even better ! It has more interior room, loaded Premier option level and feels so much lighter to drive down the road then that heavy lemon

You said, "Traverse" LOL.

Just kidding, you're funny mentioning your buddies giving you crap. But seriously, I feel bad for you, that truck looked tough, but in the end if you can't drive it and be comfortable, it doesn't matter how good it looked!

I took mine in to be looked at today on the advice of GM customer service.

when I got to the dealer I showed them the TSB and my case # from GM- i was told I would have to pay out of pocket for the diagnostic since I am out of warranty. I then proceeded to call GM customer service from the service managers desk- at this point I was told there is nothing they can do for me if I was not willing to PAY for them to diagnose it- I took my keys back and left. I am extremely disappointed.

the unfortunate thing is I have no recourse since it was purchased pre-owned I cannot even file lemon law if I wanted too.
