2015 YUKON NOISE IN CABIN

[yahtzee]

 

I think I have right, but to date you've only had tire work done multiple times to your yukon and nothing else?

 

No. They also balanced my drive shaft. :-)

So what exactly did they do to help with the booming and buffeting sounds?

 

Nothing that I am aware of. They have been focused on the vibration issues.

I didn't observe the repair but here is what they said they did.

 

They initially attached the first bow behind the sunroof. There was a small improvement.

They then reattached all roof bows and as they described used extra material whatever that means. The dealer decided on their own to add Dynamat. Keep in mind they drove a few vehicles including mine without the headliner and observed the issue first hand so I suspect they had a good handle on what they needed to do. They got permission from GM to add Dynamat.

They ordered a new headliner because they said the original was getting beaten up and they wanted it to be pristine.

 

The end result is the truck is great. I just drove 1100 miles this past week between San Diego and LA towing a 4000lb generator half of the time and am nothing but impressed with this truck.

Frank. Do you live in So-Cal ? If so, I'd love to talk to the service manager at the dealer that did all the work on your vehicle. What dealership did all this for you, if I may ask?

I am in San Diego, I went Quality Chevrolet in Escondido. They did a great job and I would recommend them. The gentleman I spoke with is Dave.

Hey guys. I've got a brand new 2016 Tahoe LT with the same buffeting sound. I'm so sorry I bought it now. It makes me sick to think of the money I spent on the car. I'll take it back to the dealer this week and hope I can work a buy-back.

You don't even want to least give them a chance to fix it?

I would love to give them a chance to fix it. In fact, I'm sure the dealer will not buy it back before giving it a thorough run through. However, in over 1,400 posts to this thread, I can't find a "silver bullet" that is causing this problem. I've read everything from tires, to driveshafts, to windows, to roof bows. Maybe I'm missing something, but it seems like the dealerships are shooting in the dark. This is not only an unfortunate problem for owners, but I'm sure it's costing the dealerships a fortune to keep working on a problem that appears to be a fundamental design flaw.

 

Do you have any advice when it comes to my first interaction with the dealership? Thanks.

I do. Print my posts where I describe what was done to my truck. Have them drive your truck with the headliner removed so they can see the buffeting in action. Print up the July TSB and show it to them.

Ok. I'll do that. It sounds like there is at least one other user that has had success with your procedure. I'll let you know how it goes. Thanks for the info and advice.

regular window gasket seal tape on top of the oem seal should create a tighter seal(jus for troubleshooting purposes)

Dear CI, I feel that the glass should be close and tight to the window frame. Seal tape would still put the glass away from the frame a bit as you are moving the glass away from "home base" My glass is very tight and close to the "frame". Took my wife to the grocery store today. Drove up to 85 mph on the back roads and still no problem. The only "Boom " I heard was the XM station that plays R & B. I love the Stereo in this car. So far , I love this car. It drives like........ A Limo. I also have my fingers crossed. Good luck to you and hope you can resolve your issue. With best regards, Booty

Frank, I read that you bought your vehicle from Quality Chevrolet in Escondido. Do you remember the name of the service manager or technician that you dealt with? I'd like to put my dealer in contact with them. Thanks.

Actually, we bought the truck in Buelton, CA, we had the buffeting issue serviced in Escondido closer to home in RB.

Update....

 

Dealer installed 2 new tires and road force balanced them. Put them on the rear. Installed the suspension update per TSB - new struts up front and shocks in back. Plus, update chassis module program.

 

Result - no improvement to the booming/buffeting/drone. No noticeable improvement to the rise harshness/noise. But, noticeable degradation to the roof and pitch control. The vehicle wallows about like a '72 Caddy with no shocks at all. Terrible ride now. Completely lost the responsive ride of the Denali package without improving any of the issues in the first place. Big disappointment.

 

My recommendation....avoid the suspension update. And tires changes are a waste of everyone's time!

Yes, that was done back in the spring. C/w Dynamat. No improvement.

Did they reinforce all roof bows?
