2015 Yukon/Tahoe - Ear Pressure / Buffeting Problem - POST HERE!


Recommended Posts

Since the "Noise in Cabin" thread has taken a different path to try to solve the problem, I'd like to start a new thread for the folks who are having the issue specifically. It seems there are more and more people joining the forum to post about their ear pressure/buffeting problems, so THIS IS THE THREAD FOR YOU!

 

This new thread can do a couple things:

 

-New members can post here instead of their info getting lost in the "Noise in Cabin" thread

 

-Compile a list of people who are having the issue - new and currently posted (Everyone REPOST)

 

*MOST IMPORTANTLY*

 

-Make it EASIER for GM to notice the amount of people who are having the problem!

 

In this thread, please post any information that is useful - Make - Model - Problem (pressure/buffeting), Repair work done, etc.

 

If existing members fail the repost in this thread, I'll search all 600+ post for their names and their post in the "Noise in Cabin" thread and repost it here - all to compile names and situations into one thread!

 

POST UP, EVERYONE!

I'll go first:

 

-2015 Yukon Denali, 22in Q7M wheels w/ Bridgestone's, purchased Oct 2014

 

-NO buffeting noise, but EXTREME ear pressure while sitting in/driving down the road. No certain speeds, but rough road noise makes the pressure worse!

 

-No repairs done as GM has NO FIX - I have completed the "Cotton ball" idea on the ANC system and have reduced the pressure 95%!!

 

Edit: Location is SE Tennessee

The 100% method to get your concern "heard" is to take it to the dealer and have the issue logged. Even if there is no fix this will still show up and the more times it is logged means it may be looked into more seriously

 

Also you may want to mention your location as elevation could play into the issue?

 

Just curious does the issue happen with windows up, one down, 2 down, all down?

GM needs to be made aware and FELT in their pocket! Do you realize how many people have avoided and even canceled their Yukon/Tahoe orders because of this forum??

 

GM Customer Service has said repeatedly that they monitor the forums, so GM knows about it... Heck, every dealer many people have taken their trucks to get the same ol' "this is the first time we've heard of it" spill.

 

This is a public forum and can't be "silenced" by GM.

Where does "silenced" even come into play? Ryan is trying to assist and not silence you. He could or I could if we really wanted to. You need to deal with GM in a different way. Take it in weekly for the issue and make sure it is logged. The more annoying you become means GM sees it as an issue.

I didn't specifically say Ryan was the one trying to silence me. I apologize if I came off that way. What I did mean, though, is that GM is just throwing ideas at the problem and not solving it. There was a post where a GM engineer even said one guy's truck "wasn't as bad as others out there". My dealer has been made aware of my particular issue and pulling the headliner is their only solution. Not happening. I actually fixed my problem with cotton balls. Yes, cotton balls...

 

All I really want this thread to be is a place where everyone w/ the issues can be compiled into one topic.

First, thanks to 20Sierra14 for starting this thread.

 

2015 Yukon XL Denali

Took delivery end of Oct 2014

22" wheels with Bridgestone tires

Has the option package that includes the HUD, rear DVD,

2nd row buckets

 

Issues include:

- drone/tunnel sound at all speeds, even as low as 15 kph. Like being in a tin can. Almost feels like a pressure sensation in of itself.

- buffeting/pressure sensation at speeds above 60 kph or so.

- a lot of vibration felt in the steering wheel and the seat.

 

Comments:

- drone/tunnel feeling is almost always there.

- buffeting seems to come and go.

- both are drastically affected by the road surface. Extra smooth pavement and virtually no issues.

- Feels like a stiff suspension that is transmitting every rock and slight bump in the road up into the body. Feels different then a wheel/tire balance issue, since it can be felt at low speeds as well as high.

 

No work by dealer has been done yet. Tests I have done include:

 

- turned off the entire sound system, which includes the Bose Noise Cancelling system, by removing the fuse that powers the main audio amplifier. I did not see any difference in the issues. Everything noted about still present.

- turned off the Magnetic ride shock by removing the fuse that provides power them. Again, did not help. Issues still present. (Might try this again. Was a long time go and I don't recall if the vibrations were still,present)

- taped small square of thick towel material over the microphone grills. Not change. Issues still present.

- when I hit the headliner near the middle of the vehicle with the heel of my hand, I hear the same sounds as experienced when driving. May be related.

 

I hope everyone with this problem posts here so we can get a good list of folks. Also, if there is interest, it may be worth setting up a formal registry, with actual names and locations/dealerships. Not sure how to do that a respect everyone's privacy, but I'm sure there is a way.

This is crazy. Wish I could drive in your cars and see if I experience it myself.

 

Need to drop it off at a dealer and make it GM's problem. The more people complain and clog up the service schedule, the faster GM will find a solution.

Here are my two posts on the topic. 2015 Suburban LT Luxury package (Bose Audio included), standard 18" wheels, August build date I believe.

The ANC may play a part in this but there are vehicles that don't come equipped with it as far as I know. I flat out asked a GM engineer if my 2015 suburban LT had ANC was told it could (or not) but there was no easy way to tell without investigation of the radio and software installed.
A post awhile back indicated that perhaps the suspension was too stiff and what some are experiencing is vibration resonating up through the cabin. For my vehicle, I believe this is exactly what happened, and the key word is resonate. As an easy test (with or without a fuse pull or cotton balls) first find a section of road with a nice long row of raised center reflectors, usually spaced a few inches apart from one another. Driving safety comes first so you may want to do this when no other vehicles are around. Stop your vehicle and then slowly drive the driver's side tires over the reflectors, slowly increasing your speed to 5 -10 MPH. Maintain whatever speed you get to when the vibration starts, about 8 MPH from what I experienced.
The first thing you'll notice, at least I did, is that after a few seconds the interior of the cabin will shake and vibrate like there's an earthquake inside the vehicle, and the longer you drive the worse it gets. I am NOT exaggerating about the level of vibration here, it feels like the vehicle will shake apart. I would only drive with this shaking only for a number of seconds in fear that the vehicle would be damaged somehow. The second thing you'll notice is the pressure building up and the buffeting sensation reported here in this thread.
So, could it be the ANC contributing to this, I don't know, I'll defer to the acoustics experts here and at GM. What I do know is that I've never driven a vehicle that vibrated and shook like this before. I did the same test with other vehicles and yes, you feel bumps in the road, but the steadily increasing vibration and buffeting sensation, no. I drive on mainly smooth roads but I can only imagine the frustration by those with this issue AND with a long gravel driveway or daily drives on less than perfect pavement.
I ended up cutting my losses and trading out of this vehicle so as not to deal with the headaches, literally and figuratively. I wish you all the best and hope GM can come up with a fix as the new Suburban/Yukon/Escalade is a fantastic vehicle otherwise.

Based on my experience, the pressure in your ears sensation is most pronounced over rough/gravel roads at low speeds. From my previous posts I was able to recreate the pressure "at will" by finding a stretch of road with some raised reflectors. You could also try the side of a road/highway that has rumble strips. Pull over and stop, drive slowly with your driver's side wheels running over them, increase speed to about 7-12 MPH, and continue to drive at the speed where the pressure/vibration/shaking starts. After a few seconds the vibration and pressure continues to resonate throughout the cabin until it is unbearable.
I don't want to discount that the ANC plays a part here as I agree with most that just sitting in the cabin didn't "feel right." It was a very similar "feel" to wearing noise cancellation headphones on or off a plane. The main difference is that you can just turn OFF the noise cancellation with headphones. It's a shame that there is not an option to disable ANC via the settings menu in these vehicles (or any vehicle for that matter) as it's an not a desirable option for everyone. I would bet real money that disabling would be relatively easy to do in software. Why GM is not offering this option as a potential fix, I don't know, but I would also bet there is some real cost/benefit/risk mitigation analysis going on within certain departments....

2015 Yukon Denali.

Purchased July of 2014

No added packages.

No Sun Roof

20" Polished Aluminum Wheels(SLT Wheels)

 

I just picked up my Denali from the dealership after they removed the headliner and added the foam as instructed by the GMC Bulletin. The dealer sent me pictures of the "2 back cross members" where they had become detached before they "fixed" the issue.

Well nothing changed at all. Still have the pressure and buffeting at certain speeds. It is unbearable at 42MPH while coasting downhill. This is the first time I have spent a good amount of money on a car. Major buyer's remorse.
