What is the chance that GM would fix the vibration/buffeting issue in 2017 models?

[WillCO]

I agree, that net mesh for the wind deflector sucks!!!!!

It's substantially quieter when you pull down the mesh; I do wonder what they were thinking there.

I wonder if this buffeting issue is some kind of artifact of the truck riding on essentially an ancient frame technology. The rear axles on these are essentially the same design as they were in the 80s. They don't break, though.

Not making any claims, as I have no data at all - so nobody flame me to death. I will set forth a hypothesis that the people who are noticing the "buffeting" are people who have not driven this kind of car much in the past.

I've never removed the mesh/net to see if it's any quieter. But I know in my 2008 and 2014 Tahoe's that had the solid wind deflectors were very quiet when opened.

I would say a high percentage of folks on other "buffeting" threads have owned multiple tahoes/yukons/suburbans over the years prior to the latest model, including myself.

I've also been in many vehicles with similar sunroof screens and they have never been as annoyingly loud as our Yukon.

I saw my share of rear ends break in F-bodies (4th gen Firebirds/Camaros), but mostly with those running big power or sticky tires. The Ford 9" was known to be nearly indestructible.

One significant change that is worth noting, apparently, "American Axle Manufacturing" who makes our axles, recently moved their operations to Mexico and touts a new machine which can machine our ring/pinion in 2 cuts instead of 5. I'll never know if this is why I had vibrations. I do know that a complete axle replacement eliminated my vibrations.

The buffeting is not normal body-on-frame noise. The previous generations did not have it, nor does the competition, at least the ones that I drove or have been a passenger in. All this "Shakerado" and bufetting talk really only got steam with the new K2XX platform which started in 2014 for the pickups and 2015 for the SUVs.

I do agree that one shouldn't expect car like sound levels in a truck, but now that my wheels are balanced, it's pretty damn quiet at any speed!

The dumbest design decision I've seen. The sunroof is pointless driving on the highway as it's so loud when open

 

[Cha0s13]

Ive stated it before, although I love the look of the new Tahoes, I wish I never traded in my nnbs 2014 for the 2016 I got ;(

What is this mesh everyone talks about. Do you have any pictures. I have a mesh thing that came in the rear seat no idea where it goes or how it works.

 

[Deuce16GMCs]

Went to my dealer yesterday to discuss my repurchase/exchange.

Drove a 2017. With 20s instead of 22s, and no vibration at all.

Buffeting and booming still there. Actually worse than my 2016.

Although my 2016 wheels have been RFB to 15lbs or below.

So I guess even if the 2017 with 20s doesn't vibrate, we'll still need to RFB them down to 15 or lower.

But I'll probably buy Michelins from the get go.

the air deflector screen for sun roof


i assume the mesh is the net that was in back seat is for rear cargo area

 

[AngelXL]

That net is for something else. The mesh is already there.

Just picked up a new 2017 Escalade Premium. No vibration of any kind.

Any buffeting at 40 and 70 mph.

Or booming at low speeds?

 

[MTVP]

No not as of now. Just like the Porsche Cayenne I just sold . I have a db meter app on my i phone 6 +. I get a 89 db reading in the Escalade @ 80 mph as well. So I have to say it is quiet enough. That is the only comparison I have to go by.

89 db is loud. There is no way that app is accurate. If its true that is definitely not good sound levels.

 

[MTVP]

That's what I thought. Free app you know the quality. Inside the vehicle it is pretty quiet , Escalade or Porsche.
I just checked it setting here next to the desk top . I got a reading of 57 db in a quiet room.
As I said before, it's all I had to go by.
I just remembered I have a sound meter from my old Home Theater days . I'll have to dig that up.

I looked at the 2017 Tahoes while my 2016 was in for recall service. It may just be me, but I thought the 2017 Tahoes doors feel heavier while opening and closing them. I also have noticed since the weather has cooled down, the low speed body booming over rough roads has gotten worse. I saw somewhere that someone claimed to have remedied some of these issues by lowering the stance of there Tahoe.

I've had 3 Denali's. Early build 2015, 2015I, and now a 2016. I have not experience any of the buffering that I hear people talk about on this forum. All of them had 22's , 4X4, and fully loaded except for the security option. Maybe I'm lucky.

Did you notice any booming sounds over bumps at low speeds? Two out of three Yukons I test drove rode perfectly but one of them made a booming sound going over bumps that would've drove me nuts if I bought it. It was very pronounced.

 

[Chris T]

2016 Yukon Denali 2wd on 20's here. Drove quite a few with buffeting (didn't know it existed until we drove several of them, then googled it). Finally found this Denali. It booms over low speed bumps and gravel which I attribute to the Magnetic Ride and sheet metal/design combination because like Cha0s13 says above, it gets worse in cooler weather. Our Denali has no buffeting and no vibrations as of about 5k miles.

Interestingly I had it in for the airbag or whatever recall and I requested an oil change. Unbeknownst to me they also rotated the tires. Maybe it is in my head but after that rotation, at any speed it is the smoother and quieter than before. It is the quietest rig I've ever driven. You still feel every imperfection in the road at pretty much any speed and still have the booming at low speeds, but when the road is smooth, it is like sitting still.

2017 Denali XL 22' New Style wheel's...smooth as can be, quiet, no booming. I am fussy on the vibration or noises.
