2015 YUKON NOISE IN CABIN

[John Dell]

Well the $3500 rebate was not enough to take the chance. Had one all picked out, seemed to drive nice but as some have said, the problem often appears after a couple thousand miles. Some say its the 4v, some say only 22" tires some say roof bows and some say the ANC. I don't know. And since GM will not say if they made any progress or not I guess it will be something else. Sad but true. Very disappointed in GM as it is a really nice looking SUV but I just can't risk it. Sometimes I wonder if the problems are built into all of them, and some people are just more sensitive to them.

I truly believe this is the case. I also think there are ways to combat (not that we should have to) the issue to make it close to perfect. We still have a slight hwy vibration at 75+ but swapping out wheels and tires and having them RF below 15lbs drastically improved our buffeting issue and we are now around 8k miles since the change. This is coming from someone that couldn't drive our '15 XL more than 15min without feeling sick. With that said, to me these new trucks still ride way too firm and choppy compared to the previous version and other trucks. Hopefully it will get corrected at some point.

Do you know what exactly cause that feeling of sick ? Is it tires balancing issue or maybe pressure inside cabin because of buffting .. anc ?

[the blur]

There are 10 zillion of these trucks on the used car market. Obviously there is a serious problem, and GM doesn't seem to care. I see them at Infinity dealers, Audi dealers; used, low miles, like new. So move on, get something else, because there is no cure. Only band-aids.

 

And to the guy who had 2 brought back, and then you brought a 3rd...... shame on you. I love GM, and it's the only cars I own, but I would never by a 2015-2017 GM truck due to this. Let common sense prevail.

 

 

Me personally, I brought a clean 2014 with 30,000 miles. Because I'm tried of reading about this.

It was definitely due to the pressure/buffeting feeling. I'm sure the tires that were on it were just fine, it's just that there is something wrong with these trucks that make them extra sensitive to just about anything that's not 100%. I was days away from trading in for a 13/14 but since we purchased used, I was willing to try a few things before taking a huge loss and so far the new tires and wheels have done the trick. I am sure GM knows what the issue is and it's most likely a bigger deeper problem that won't get resolved until a slight design change occurs.

very true and many of them show up as "GM owned" vehicles after they were sold which means they were most likely "buy backs."

what size wheels you running and what tires did you go to

[ajs800]

Michelin Premier LTX stock size on denali 20" wheels.

I have been thinking a lot about this lately, mostly because I want one but will not buy one with these known problems. Here is my idea to anyone that is inclined to try. The GM tech said it is like being inside a drum, his words. The problem is most likely part of all of them but some people as more sensitive or have perfectly built suv's with no tire or other small issue's to enhance the vibration/pressure. All automobiles have small vents built in so on a hot day it can vent and not blow out a window. That is where the problem occurs. Air moving in and out maybe not fast enough and because of the body panels being so thin it can't keep up. Its no coincidence that this problem came along with the thinnest sheet metal ever. So it must be thicker to avoid vibration from any other influence. If anyone has one and some spare time, I would buy some roll on bed liner, maybe even thin it a bit, and remove the 4 door interior panels, and coat the inside of them, then remove the rear tires and plastic inner fender wells and do as much as the quarter panels as possible, you may need to remove the plastic on the inside of the the suv to get the upper parts, same for rear tail gate but the hard part and most important is have your dealer remove the headliner cover seats well, and do the roof, especially the front half as it does not have ribs it is just flat. The front fenders and hood are not part of the cabin so likely not needed. This will cover all the large flat areas that can easily vibrate. On a side note, has anyone had their suv aftermarket undercoated and still had vibration/pressure issues? This would add mass to the body panels but not the roof, especially the front half where I think most of the problem comes from.

There is nothing to think about. $10 Million dollar GM engineering department certainly knows what the problem is. No doubt about it.

 

What is baffling why they don't issue a conclusive TSB.

 

My guess: the body style probably needs a redesign to eliminate the problem. And a redesign for these trucks is too early, & too costly. They would need to retool the entire production line, and the model is only 3 years old now, and they usually run models 8 years before a redesign.

John the booming is there even with windows open i.e. no pressure difference between inside and outside cabin

 

If you're bored, start at page one. EVERYTHING has been attempted.

 

So far the best results by far have been to get 20" wheels and road force to 15lbs or lower.

 

This assumes your vehicle only booms (think flicking a subwoofer).

 

If you're vehicle vibrates, that's a different story.

[John Dell]

I have read every page and my heart goes out to all who have suffered thru this mess. I don't believe anyone tried this, they tried Dynamat, but that is very flexible. The drum or subwoofer feeling will be heard/felt with windows up or down. Just my two cents worth, I don't have one so I can not say what it is like, I want one but not all like this.

This is too extensive coupled with getting a dealer to agree to removing the headliner, I don't see this happening. What makes you sure of your comment. As opposed to what you said, my truck has not been reinforced with anything and never buffeted or vibrated. For trucks exhibiting problems, I think the solution is more complex than just reinforcing the density of the metal.

A minor redesign will naturally happen in 8 years, maybe 7. But that's about as much as GM can do based on retooling and inventory, I agree with that. For me, the current design being a problem is unlikely, since my truck's performance is getting better.

This is just that, a hunch, thinnest metal ever on the stiffest frame ever and a booming sound. My opinion is that there are many factors. Some people are more sensitive to little sounds/feelings. Some trucks/most trucks may not show any problems if everything is perfect as it sounds like anything not perfect causes the body to vibrate. Perhaps you are getting your truck closer to everything else being perfect. Yes this is a big under taking and could only be done when the truck was in for roof bow service, then the rest done at home. I am curious, what about your truck, how is it getting better?
