2015 YUKON NOISE IN CABIN

reels · October 22, 2014

I know I can duplicate this effect on all of my suburban type vehicles I have owned by cracking a rear window by itself. I understand this is happening with all the windows closed on the new body style, but wonder if the fresh air intake is causing the pressure to rise and fall in the cabin creating this butteting noise?

Hi Guys

I just called the dealer and canceled the 2015 Yukon Denali XL that was on order. There is no way I can feel confident with this purchase knowing what I do about this vehicle and lack of GM doing the right thing at this time.

I also as others have stated want to get one but only when I feel the issues have been corrected? Major repairs being done to a brand new vehicle is not what I can deal with.

Time will tell if and when they resolve this. I will keep monitoring the site and hope for the best.

Thanks to all of you that have posted this information to help protect the customers.

I was very fortunate to have found this site as it allowed me to have the knowledge of issues most will never know exists till it’s too late.

Thanks,

Snuke1e

Good on you Snuke1e - suggested this to you on page 6, post 88. The only way GM will fix the issue is when it hits them in the pocket. You did the right thing.

Same here. When i know its corrected, will talk about an order.

Tobek ... noise, sound, what creates it, how to stop it (in say, submarines), and how to enjoy it is my profession (Acoustician). They measure the gap to determine if there is separation of the roof panel and the crossbars and hence, repair is required (buffet or no buffet).

I don't see any evidence of GM doing anything more than guess work on a fragmented basis (multiple people in different locations with no coordination of effort). Here's a starting point:

1. Drive the vehicle on the open road noting the vehicle speed, engine RPM, and taking full spectrum measurements to 10Hz (possibly lower, but that equipment is very expensive and likely only at GM HQ).

2. Change the speed of the vehicle but not the RPM...measure and note any changes.

3. Change the RPM of the vehicle but not the speed...measure and note any changes.

4. Take the vehicle to a dynamometer facility and repeat the tests and measurements (this will isolate aerodynamically induced issues from mechanically induced issues).

5. Place vehicle in a wind tunnel and test at various wind speeds.

Items 4 and 5 may be mutually exclusive and by the time you get done with (3), evidence would be pointing to mechanical or aerodynamic forces and would then lead to tests 4 or 5 to get closer to the root cause.

Now, I can assure you that is very highly unlikely this very simple set of tests have been carried out by a dealer or on a district or regional basis. More to the point I seriously doubt anyone has measured the pressure and frequency in order to back into a potential cause. So, what we most likely have here is sloppy assembly followed by sloppy fault diagnosis which will lead to finding no root cause and a bunch of time and money being spent on customer owned vehicles to guess at a solution.

In the news this morning, GM posted a net income of $1.38 billion for the 3^rd quarter of 2014 (Jul - Sep), this number nearly doubles the net income from this time a year ago. Revamped pickup trucks and SUVs were responsible for the push; 60,000 more vehicles were sold this quarter as compared to the same quarter in 2013.

GM Chief Financial Officer Chuck Stevens comment, “The new trucks and SUVs are more profitable than the ones they replaced. That certainly helps from a profit perspective”.

The reality of GMs profit, more folks will have to decline delivery of their new SUV for GM to pay attention to this issue. There are a lot of 2015 trucks out there and with profit margins like this, Snuke1e’s truck won’t be enough to impact GM’s bottom line and force a fix for current vehicles already on the street.

Just curious, what are the dealerships doing with the returned vehicles, just trading them to another dealership? Buyers looking at used 2015 SUV's, beware!!

Go on Cars.com there are MANY 2015 Tahoe and Yukons with very low miles forsale already. no doubt back back vehicles. Per the "lemon Law" these vehicles are to be fully disclosed to the new buyer. Doesn't mean it is always disclosed though

GM customer service has done LITTLE to NOTHING for me at this point. They just keep refering me back to the dealership. Which also has done nothing to bay back this problem vehicle. I WISH there was a different vehicle my family wanted. Real sore subject in our home right now.

Did you get a claim number from GMC customer service? That seemed to help light some sort of fire. Sorry you're going through this...just stinks. Ask your dealer to hunt down an engineer and see if they have any new information from the field.

Tobtek - the used 2015 SUVs for sale probably are not categorized as “Lemons”. From my perspective, I lay blame solely on the shoulders of Mr Mark Reuss, GM Vice President of Global Product Development. Mr Reuss has the resources to find out what happened, direct a change for trucks currently on the assembly line, and make it right for folks that have and are currently experiencing this issue.

With this issue, you and I are at the ground level, Mr Reuss is 50,000 feet up, we can’t reach him. Dealerships you and I talk to have the capacity to reach Mr Reuss but won’t dare make contact. Mr Reuss will get energized when orders and sales for full size SUVs goes down, but customer safety can’t wait on orders and sales.

Someone on this thread asked me “why am I posting, I’m not experiencing the issue”. Here is the reason; as an average American in a situation such as this, when your family feels pain, so does mine. We are in this together. The fact of the matter, it’s just wrong. Me and wrong, don’t get along. I speak with folks at the 50,000 foot level daily, I would love to “speak” with Mr Reuss. Right now, he has to be the biggest “Lemon” at GM.

GM Customer Care roaming this thread, are you an average American. Shoot me a PM.

Yes, have a claim started at GM Customer care. Have been told from the Service manager to come get the truck, he can't hear it.

They have had the truck two weeks now, STILL cant tell me why our truck is different from the rest and CAN NOT run E85 fuel as advertised.

Between the sound issue, the E85 issue, and the other things that have already broken on this truck. Im not impressed at all. Now looks like its time to find a buy back attorney. This will cost GM alot more down the road, Vrs just taking care of it now. They will be paying any and all payments made, Full down payment will be returned, AND they will be paying attorney fees. BMW used to do this all the time as well. Would save so much time, energy, and money for everyone if they would just step up and do the right thing in the first place.

"just step up and do the right thing in the first place."

What an incredibly bright idea! I wonder why those in Detroit who know better than any consumer anywhere on any day haven't figured that out yet? ;-(

subedriver · October 24, 2014

well heres a quick update on mine. the service manger said he feels like he has done everything in power to fix it with no avail. the dealership it self won't just buy it back, I'd have to start the process with gm for that. Instead the dealership is going to find me a used low mile infiniti qx56/qx80 and I'll pay the difference they will then just unwind the tahoe purchase part of my deal. told them to do that so I don't have to fight gm and wait even longer to get a different vehicle. good thing is i'm still in my loaner vehicle and plan on keeping it until they find me a infiniti

FOURKNUCKLES · October 24, 2014

Lemon Law is completely different than a buy back. Lemon Law means that the car is defective and that would need to be disclosed. A buy back, is a buy back. I went over this with the dealer when they were hesitant to buy mine back. Once I stated that I knew the law, and that I would be filing a claim, presto, a buy back was offered. They did ask if I had legal representation. If you tell them yes, they will stop working on the vehicle, and everything will go through GM and the attorney. I assume profits are up because of the hap hazard way these new trucks are being produced.

TOBTEK · October 26, 2014

Update on ours. While the service manager at our local dealership has been nothing but pleasent, and has agreed he hears the "buffeting" or Droning sound" he's past his finding on to the GM Rep. I / we dont think GM knows how to correct this issue yet. So why tear into a brandnew vehicle at this point.

I personaly can not drive the vehicle anymore, does nothing but upset me. The truck can not even make it up my steep street without shacking and shuttering. Something is wrong with this thing, no doubt about it. Even beond the Interior sound issues. The two GM truck loaners we were just in didnt have this issue coming up our street (2014 yukon XL, and 2015 Suburban) . MY 2014 E350 MB is smooth as can be coming up the hill. The 2013 Tundra I sold to buy this POS was just fine as well. This truck is a dressed up pig! They look great, but are still a typical GM product. No quality control, and even less customer care.
