2015 YUKON NOISE IN CABIN

[xspecmor]

 

is causing what...vibration issues, buffeting (pressure issue), or both?

 

Do you have the std size or XL? WHat trim pkg and wheel size.

My Yukon is an SLE that has 20 inch upgraded wheel, we bought a month ago after trading our 2008 Yukon SLE with no issues. I find it hard to belive it has to do with the roof i think its the torque converter. I own and have 1991 Pontiac Trans Am and the transmission felt like vibration has i went to accelrate the dealer replace the torque converter never had an issue again.

May very well have something to do with the torque converter, but early in the thread there are/were trucks that had interior roof crossbars separating from the roof. Fixing the crossbars independently didn't do anything, but you can't definitively rule that out as an agitator.

I'm assuming you have the standard size?

 

I am sure the tranny/pwr train contributes some but I get the buffeting when putting truck in "N" and coasting at 40-50mph. This pretty much rules out motor mounts and anything pwr train related. I have the v4/v8 lugging/vibration issue as well but I'm not too concerned about that as I know that can be somewhat resolved with updates.

I find it hard to believe it has to do with the roof I could be wrong but think you would hear at all speeds

I compare to other vehicles when you roll a single rear window down while moving...severe buffeting occurs with most vehicles at different speeds...but not at all speeds. This tends to be normal. My grand cherokee with only one rear window down has bad buffeting at approx 35-40mph up through 50 and then of course it's bad again at 65+. Most cars will do the same thing with only one window open near mid or rear of vehicle. All windows up and sunroof closed, never, unless you're driving a 15+ yukon / suburban.

 

However, being that some claim not to do it goes against the aero/design flaw idea. I could be wrong, but for ears to constantly pop and dizziness to occur, there's got to be a pressure issue within the cabin and not just a "noise" issue.

true but I believe there are yukon/suburban/tahoe folks that have resolved the vibration issues but not the buffeting. As much as I'd like to think it's only a vibration issue, I'm afraid there's more to it. The buffeting is horrendous in our yukon xl at 43mph when on a very smooth newly paved road all while there are no vibrations present in the steering wheel, seat, doors, body, etc.

 

I believe both get resolved. Has anyone even tried the updates gm has posted?

To my knowledge, GM has never placed one of these problem vehicles in a wind tunnel. That would definitively determined if the problem is mechanical or induced by air flow around the vehicle (vibrating panels).

These trucks have an element of noise (larger engines, thinner metals, bigger wheels) and pressure (buttoned-up jelly tight compared to gen 2 and 3) that I believe is managed together, get rid of one and the other is unbearable. GM has been in the truck business too long not to know this, so the only thing to do would be to manage it. Gen 2 and 3 didn't have the noise or pressure (I actually owned 2, 3 and 4 at the same time), so with GM knowing about the increased noise and pressure in the new gen 4, what could they incorporate to manage it?

I would like to think an engineer would have thought of this with some of the early buybacks, but you never do know. That would determine a lot, IMO. However, I would also think, at least one if not several engineers would have noticed these issues when field sampling/testing the design 2+years ago.

Congratulations to GM! Not only can they misrepresent vehicle features, execute sloppy engineering and provide zero customer service, the Tahoe/Yukon/Escalade has won a spot on Consumer Reports 20 most unreliable vehicles. Way to go! At least they are consistent.

Hopefully, this is the type of publicity will force them to do something about these issues. All 3 2015 vehicle platforms made the list. This vehicle needs a redesign. I just hope the taxpayers won't have to pay the bill. Again.

Man, there are some nice cars on this list. If it wasn’t for all the safety enhancements, you may be better off keeping what you have. But the fullsize SUV problems doesn’t surprise me, it’s been talked about this thread for close to 2 years. Although the Yukon and Tahoe mention things I’ll have to keep my eyes on, the XL versions and the Escalade mention engine and driveline vibration. This should be where dealers focus their attention when complaints come in about shaking and vibration.

I think I may have uncovered why the vehicles may be making these noises is it possible with the new front end of these vehicles the bumper doesnt allow air to circulate since the lower part of the bumper is blocked. The previous generation SUV had the lower part of the bumper that allowed air to follow thru. I notice all large suv and trucks have the grill and cut out in the bumper to allow air circulation.

Kind of not tracking with your post. The only opening in the front of my truck that allows air to circulate is the honeycomb grill, no other opening and the truck does not buffet. There is no cutout unless you happen to have tow hooks

That was Gen 3, the opening in the bumper was for exposed tow hooks and an opening for circular fog lights, don't think the engineers intended those openings for air flow.
