How many of you DO NOT experience buffetting and vibration problem?

[Kansas Eagle]

Well, THAT'S not a confidence-builder - brand new tires with a 75% failure rate? What brand?

Bridgestone Duelers. The ones they replaced them (also Bridgestone's) are fine however. I had this happen on another GM, I had a new 2008 Cadillac CTS that had all 4 Michelin tires replaced for the same thing...only in that case, the replacements were just as crappy. I ended up trashing the brand new Michelins and put Pirelli P-Zero's on the Caddy....ran perfect.

Not all that uncommon to see tires that will not balance proper due to being "out of round". I've had a set of Continentals that had this issue and also a set of Goodyears. The problem tires were replaced without issue.

To those with the buffering sounds.

First try taking off the cross rail on the roof racks. I was getting a whistle from the back that is gone. The cross members attach to the roof racks via the 2 screws on each side, what most people don't know is the crossmember attaches to that bracket by 2 more screws. Mine were loose causing the crossmember to pitch ever so slightly.
I also noticed a small lack of symmetry on the left side of the rear hatches weather stripping. Near the latch. I had them push that under the trim. Now I have just tire noise and some wind noise from the large windshield lumbering through the air.

It's a lot less noise than before.

I've had 6 Continentals replaced so far with less than 11,000 miles on the odometer. In reading reviews, there seem to be many reports of vibrations with the LX20s.

I have a 15 Denali with the 6.2. It was the owner of the Dealerships Demo. It has the vibration. It starts at 1100 hundred rpm and goes on till 1250. If i would go to manual shifting at the same speeds the vibration would go away. I went to the dealer and had it checked out. I was told that there was a service bulletin on this and the service manager said that it was the torque converter issue. On the drive home after it was fixed, not only was it still there i was worse. Now it starts at 1100 rpm and goes to 1600 rpm. The vibration is about the frequency of a bad ujoint. The rpm also fluctuates about 200 rpm in this area. I drive the same route daily for 6 miles that puts in that rpm range, the vibration is always there.
Bringing it back to the dealer tomorrow.
I have had many cars and trucks. Alot of them have been heavily modified and these were new cars of the lot. None have ever had this bad of a vibration.

I just picked up a 2016 Denali 2WD base configuration. I did not experience any buffeting. I did experience minor buffeting on another similar Denali at a different dealership.

2105 Tahoe with sunroof. 13k miles with no pressure/buffeting. FWIW, I've driven/ridden in countless PPV 15 Tahoes with none of those issues.

has anyone had any issue with aftermarket rims and tires?

No issues here in my 2016 Yukon XL 4x4 w/sunroof, 3:42 gears, 20" wheels. I knew about all these issues before I purchased. There was no other option for my family. Just finished up a 950mile road trip with no issues. The only thing I don't like is the v4 mode at low speed; at freeway speed it's fine. So, if I know I'm going to be driving around in town, lower speeds, I drive in M4 or M5.

What's the issue with the v4 mode?
And above 75mph you have no vibration?
