2015 YUKON NOISE IN CABIN

FOURKNUCKLES · February 6, 2015

They repurchased mine. It was not a wind flex issue. I saw the amount of material they used on my liner. Tubes of glue and more supports and it didn't change a thing.

@jasondenali15: This is with your second Denali, the 2015i - correct?

Interesting comments in an article about the "calming and tranquil environment" include:

"new shear-style mounts that act like a shock absorber while significantly improving stiffness"
"More than two dozen enhancements advance quietness in the all-new 2015 Yukon."
"Acoustic baffles in the door headers"
"the list of improvements includes a special acoustic headliner, acoustic wheel house liners, acoustic hood blanket, dash mats on both sides of the front of dash and fender-to-body baffles."
Customers are consistently impressed by the quietness of the cabin, demonstrating the SUVs’ blend of sophistication, craftsmanship and function.”

Maybe a 'new' feature intended to suppress noise is actually doing the opposite?

That sucks. How long did it take to come back?

Jason, was it OK for a while and then came back, or was it back immediately after the roof was "repaired"?

Marc, save yourself some grief. Find something else to buy. There is something inherently wrong with these things and gM has no clue how to fix it. There have only been a couple of vehicles re portly "fixed" and I don't think any were from the roof repair service bulletin.

Fourknuckles.... Did you say that the dealer added some cross braces or something? And when you say they used a ton of glue, where did they do that? I'm been of the thought that indeed this thing needs more cross braces to stiffen up the entire roof, but if that has already been tried, then that shoots that idea down.

I'm still very curious about the headliner itself. Acoustic material....ya, acoustic all right. Makes noise like crazy. LOL!

Same here... Fresh cotton balls did the trick

The Zip · February 7, 2015

jasondenali used mic plugs, but he never took a picture or provided an update after it was installed, but you did provide a picture of the cotton balls, both methods worked. As for the cotton balls, the headliner is flattening them out or they are just moving. If you can stop either from moving, the time without pressure may be extended. The headliner movement is a big deal, but we don't have a lock on that, yet. But the cotton balls worked, so if you stop the cotton balls from flattening or moving you may have something. Try taping the cotton outside of the mic and inside the O ring, put the grille back in place, then tape the grille instead of the cotton. If you isolate the space occupied by the cotton balls, headliner movement may not affect them or have a decreased impact.

Went for a ride today. I rode in the 3rd row and my wife drove. I pushed up on the headliner in numerous locations, and she said it made no difference to the noise. Sitting there, I observed very little movement of the headliner.

Not sure if anyone would find this interesting, but I have continued my search for another vehicle comparable to the YukonXL, Denali after giving up on these vehicles due to what I've experienced and all reported in this thread. To know avail, nothing, we even tried the supposively new designed FORD (ick) Expedition Platiumn. Big sales pitch, less wind noise, much quieter? Drove 5 short and long, couldn't believe it, everyone of them! BUFFETING, EAR AND HEAD PRESSURE!! Painful! Everyone in the vehicles, even the salesman felt it. What the heck! Ridiculous!

Now, that is bizarre! Totally different vehicle doing the same thing! What's the odds of that. The only thing they have in common is a big, long, flat roof.

Wrench589 · February 8, 2015

I suspect all the manufacturers have been dealing with this issue for some time now. I doubt it's unique to this particular model from GM.

Is the noise/pressure present if [those with] the sunroof have it tilted open?

Ambient Air Vent?

What happens if it were stuffed with cotton and maybe duct taped?

What makes you think that?

Yes that is strange. Sounds fishy...
