@Ozzii, can you ask your dealer for a reference to information on the new exhaust components? I'd like to get my dealer on-board with getting the parts ASAP.

ajs, there is a TSB for the rough ride if equipped with the magnetic ride suspension. My Suburban LTZ had the same issue and following the TSB my dealer replaced some of the suspension components (shocks and struts I think). It made a significant difference in the harshness over bumps. Yes, the feel is more disconnected from the road but it's a land yacht, not a sports car, so it works for me. Mine is a 2015i, and I was told the updated parts are standard on the 2016 models.

Hello All. Can someone who has had their vehicle recently serviced for the buffeting either post or PM me the latest service bulletin number their dealer is working off?

@jeeps, that is interesting. Can you tell me what the flaps actually look like or post some pictures? Sent from my Nexus 5 using Tapatalk

I think he meant from inside the cabin. If so, I don't think there is such a button for just the glass, only the entire tailgate.

Did they offer you a loaner? Check your State's Lemon Laws, as that may impact the number of days and/or eligibility.

Most of what has been posted points to GM thinking this is a vibration issue. Based on my experience, I agree. Just search my posts here and you'll see I was able to reproduce the pressure and buffetting at low speeds by exciting the chassis. I started off with the buffetting at 39 MPH but it would occur at other speeds too. BTW, replacing the entire rear end practically eliminated it at 39 MPH but as I said it reared it's ugly head at other speeds. I would assume GM knows this is a real I issue but is quietly sweeping it under the rug, well, because they can. My bet is that the 2016's will not have this issue (or it will be less noticeable) but we'll have to wait and see.

2015 Suburban LT with the same "pop" occasionally in the driver's seat. About 4,000 miles but it's been doing it since 750. I never did anything about it but wanted to chime in as it's clearly not an isolated issue.

I need to look at the TSB again but have to ask why glue is being used at the factory. Isn't it metal on metal? Why aren't they welded if that is the case? Good info on the dynamat, thanks.

Mine had buffetting with the max trailering package, yes.

I second that request for part numbers if the ride is that much better.

I too am encouraged about the new new shocks and smoother ride. Is your Escalade the long model or regular length? Buffeting seems more common in the longer models. Was it diminished at all after the new new shocks?

All of these fixes, at least what I can surmise, target one main factor - vibration. So what happens when a tire gets out of balance again? I am not convinced any of these fixes will last long term. In my opinion, something in the design needs to be changed. I'm hoping we hear more stories of newer builds not exhibiting the issues but for existing owners with earlier builds I don't see much in the way of a path to a solid fix so far.

@jason, the 4 wheel drive issue appears to be related to colder weather and is a known issue without a fix for some at this time. Check this thread. http://www.gm-trucks.com/forums/topic/169213-4x4-will-not-work/

I've been in the vibration playing a significant role camp since first finding this thread. If I'm not mistaken the suburban, Yukon, escalade all share the same platform with the new Silverado/Sierra introduced with the 2014 model. Just do a search for Silverado vibration and you'll find a bunch threads and videos. I actually drove a 2014 Silverado and it had similar buffeting. Then a buddy got a brand new 2015 and it had zero. They were the same trim level but the difference was night and day. The 2015 drove like a caddy! Sent from my Nexus 5 using Tapatalk
