ANYONE ELSE HEARING LIKE A BUFFERING SOUND? MAKES YOUR EARS FEEL LIKE THE WINDOW IS DOWN, BUT IT IS NOT? I TOOK IT BACK TO THE DEALER, THEY HEARD IT. WE GOT IN ANOTHER 2015 YUKON XL AND HEARD THE

I've had my 2015 Yukon XL back for 1 day after it was in the shop for over 3 weeks (this time). The buffeting is the exact same, with no improvement whatsoever. I am having 500 cheap business cards p

Hi all,   I created an online survey to better quantify the issues surrounding our trucks. The goal is to get more accurate numbers. The survey is open to *everyone*, including those with no vibra

So, I am having similar issues with my own ride (with regard to the pressure buffeting). Tell me if this sounds familiar:

 

Buffeting felt in ears as much as heard

Headache inducing in some cases

Triggered by any kind of bumps in road (big or small)

Washboard surfaces are the worst

Large wheels and low profile tires (21" rims)

 

Tried road force balancing - no help

Tried switching to smaller rims (19") and tires - no help

Tried sound deadener - no help

 

Now for the kicker...I don't own an SUV. I am talking about my Tesla Model S. In all my online research, I came across this forum and this issue (you guys have the unfortunate honor of being the worst victims), as well as a few others including:

 

Last generarion BMW 3 series hardtop convertible

Porsche Cayman

Skoda (Octavia I believe)

 

Anyway, I am posting here just as an FYi. In my case, after my HOURS of diagnosis, I kept coming back to the giant hatch. I simply felt it was "moving" ever so slightly whenever hitting a bump and thus generating a pressure wave. The general assessment on the Tesla forums was you needed to adjust the four rubber hatch adjusters. I did this endlessly, but ultimately decided the rubber was too soft - particlarly for the center adjusters. I decided to unscrew them entirely, cut a couple of pieces of heater hose and put them in place. Stil rubber, but much firmer. The result was a 65-70% reduction in the buffeting. I am still working this angle, but I am definitely on the right track here.

 

Now I post all this simply as another point of reference for all you folks and to say that perhaps the whole roof thing really is on the right track and the owner who jammed in some shims (under the headliner bows I believe) was probably right. Sure, it shouldn't flex, but short of glueing some other big piece of reinforcing metal under the roof (which I would also consider), the options seem limited. Heck, if you aren't mechanically inclined (I am lucky in that regard) you might even consider having an auto upholstery shop pull down the headliner and have you come take a look and brainstorm some shim ideas. Yes, you should not have to do this (any more than I had to do this), but it may be the lesser of two evils here.

 

Anyway, as this thread helped me think up some ideas, I wanted to at least pass this on!

Anything yet? I really hoping it resolves this and I can give my service manager a second dealership that has done it.

Just got a call today to bring my Tahoe in Monday morning. Will keep you posted ;)

The Dampeners worked! No more booming over every imperfection in the road. The dealer installed 5 dampeners, part# 10199232 and ubolts part # 733-5337 The vehicle also seems to be idling a lot smoother when I'm stopped at stoplights.

Good to hear. When I get the airbag recall done I will have this done as well. Hopefully the dealer is cooperative and covers this under warranty. Maybe there will be service bulletin or something official from GM by the time I take mine in.

 

So 4 things to make this the perfect vehicle.

 

1. exhaust dampers

2. disable AFM (may reflash ECU or use M5)

3. Install Michelin tires (I will wait to OEM Goodyears are worn out)

4. air bag computer reflash

Since it isn't a written up work order I had to pay it out of my pocket but my dealer said if it solves the issue to contact GM to let them know and I should get a reimbursement.

How many u-bolts are required? If I pay out of pocket and do the work myself is their any diagram or instructions as the location of where the weights should be placed?

 

or what $$$ is labor to have them installed?

 

Looks like $300 in parts...my guess 1 hour labor?

This is good news

 

I just read that you solved the buffeting by replacing tires so is that eliminate cabin pressure also ? and what the size of them ?

Replaced the factory tires on 20 rims to Michelin Premier Ltx.

I tried balancing my goodyear tires and unplugging ANC and disable AFM nothing of this was work to eliminate my big issue PRESSURE inside the vehicle.

 

My last solution is to replace the tires but in my county we didn't have premier LTX just Michelin Latitude HR.

Wow! $400! I can fabricate some weights and mount them myself to the exhaust. I just need to figure out approximate weight and placement location.

 

The wheels in my head are spinning and my eyes are open to start gathering material for the weights.

 

I can use steel, aluminum, cast iron, etc. Create two halves that bold together. No clamp needed, engineered into the design.

Do you have some pictures?

 

The dampers just clamp on correct?

 

What's the u bolts for? Just wondering seeing why's here's 5 dampers and 4 u bolts?

Can you get pictures of where they placed the dampeners? Good news. I had GM customer care write to me on this post offering help to fix, odd I thought. Since executive told me that GM can not use this forum for diagnostic or decisions on problems. GM will definitely have to pay for the repair.

Sierra Myst, I just read off the work order they gave me. Just gave the part #s and said 5 dampeners and 4 U-bolts. Duramaxman, Ill take some pics as soon as I get home form work ;) Nice drive to work today without the booming. I actually enjoy driving my Tahoe now ;)

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
