2015 YUKON NOISE IN CABIN

yukontruckman · October 21, 2014

You guys dont know me from a hole in the wall, but I have been waiting for many months to order my wife a Yukon XL (cash saved and ready to buy). We figured it might be a good idea to rent one for a week or so to make sure that it was exactly what she wanted as I am not too keen on spending $60K+ on a paperweight. She has been driving an excursion for 12 years and is (was) excited. At about 30 MPH it made us a bit dizzy with the reverberating noise in the cab constantly searching for that open window that never was. Our newborn would cry for no apparent reason as it seemed similar to not being able to clear your ears when flying in a plane. The suburban had only 3000 miles on it so we figured it might just a lemon and returned it to the rental place for another. We didnt make it 200 yards out from the rental yard to experience the identical sensation in another suburban with only 300 miles on it. One had a sunroof the other did not. We are cancelling the order tomorrow and I am sure we will get the run around from the dealer but I do not trust that they (GM) will go to bat for me when the time arises, should our ordered unit have the same issues. We then rented a new Expedition and that drove like a walmart shopping cart but thats another discussion. At least we could drive a mile without headaches and dizziness. Come on GM, I will order when you promise me a fix on this issue. Its a deal breaker and I feel for the folks that have already purchased. In the meantime, The old Excursion chugs on and I earn that extra nickel a month on my savings account. Then again, I unfortunately doubt GM values my little contribution to the bottom line. Waiting for answers..

Just curious. Did you rent the vehicle to go looking for this specific problem or did you experience it and then find this thread? Not saying it is in your head, but just wondering if the sensation is minor and most people don't notice unless they are looking for it. That makes me wonder if a large number of these trucks are doing this, but many people just don't notice it. I'm in the market for a Yukon myself and trying to determine if this is an isolated problem or not.

Actually we rented the suburbans about a month ago. We rented them with the intention of 1) Enjoying a vacation for a week or so and 2) enjoying the vacation with a vehicle that we were about to be owners of. We had no idea they even had problems and were excited about it. We test drove one (actually a yukon not an xl) about a month prior and loved it. Never had any issues on that test drive that we remembered. Actually to this day my oldest daughter says she never heard anything, yep thats odd. But five others including my son say that they couldnt stand it. I guess everyone is different I suppose. If you buy one and never have the problem thats great, congratulations. When I spend 60K its a heck of a lot of money to me. That cash outlay I take very seriously. I think it is perfectly reasonable to want to drive a vehicle that doesnt make you dizzy and give you headaches. When I returned home from the vacation I searched to see if anyone had noticed the similar sound in these vehicles. All be darn.. Many have. If you dont have one that does it, or you dont notice it. Thats great. Enjoy your new ride.

The issue is real. Besides the one I owned, I noticed it on a 2015 Yukon on the dealer lot and one 2015 Tahoe rental. GM is giving owners their money back...they would not be doing that if there was an easy fix (or a fix at all). My question is: Has GMC figured out the issue before building the 2015i (mid-year build which just started), or are the "new"/current ones being built with the same flaw? I think that's the question which needs to be answered before buying one.

I just hit 3k on ours

Am i supposed to be looking for a different humming noise than the 4 to 8 cylinder annoyance?

Well said. What a monumental waste of money if they continue to build vehicles with known issues just hoping that enough customers wont notice. Seems like a little downtime at the plant (to fix the issue) would be cheaper than sending out flawed trucks only pushing the problem down the road. Then again what do i know? The warden tells me not much.

jasondenali15 · October 21, 2014

It's not a humming sound...you feel pressure in your ears and feel sick driving it. Trust me, you would know if yours had the problem by now. Glad yours doesn't have the issue.

andymac · October 21, 2014

Was just told by my dealer that all vehicles that left the plant after July 17 should have had the issue corrected. Still not sure exactly what the issue is/was. Is it the roof or something else? Anyone chime in here with a build date after 7/17?

Build date on GMC Yukon XL was week of September 11th and traveled by rail to Virginia. I received it week of October 13th. No issue with car. I'd certainly notice it.

Great news!

I'm still skeptical. So they identified a production issue in July, but they don't seem to have a fix for units produced prior to July 17th?

andymac · October 21, 2014

Agreed. Why would you buy back any units you have a fix for? Still dont know what specifically the problem is? I wont hold my breath.

Sorry to say BUT ours was built 8/22 and has the interior sound problem. Spoke with the Service manager today, GM wants to rip into our truck and see if they can find anything. Really do not want a brandnew truck taken apart. They are never the same....EVER! Having worked at a BMW dealer for 15 years, have seen plenty of cars taken apart, its not a pretty sight. Will have new rattles, sqeaks, and greasy little finger prints all over the place.

Still have not recieved any acceptable answer why we have a special Yukon that is a NON E85 fuel vehicle ???? Its in all the GM info that it is. E85 trips the check engine light, for we dont have certain required sensors ??

Just want this truck to go away, Fix the problems and we'll get a new one that performs as promissed. Tried of the stress of dealing with it. NOT a good experence GM !

Makes me sick thinking of the issues you are having. I really am sorry to hear it. I guess that solidifies my concerns that the dealer is thinking that the metal roof to rib detachment is the cause of the interior sound issue. He showed me the fix that we have all seen, but I continue to think that they are indeed two separate issues and not necessarily related. I have 40 miles of dirt road to drive every single day I cannot imagine the rattles that would exist in this SUV after a year of that. Best of luck with it. I am eager to see how they are going to make it right for you.

Unbelievable GM is going after the roof. I grant the roof panel was incorrectly secured and should be fixed. It is however highly, very highly unlikely that is the source of the low frequency "buffeting". It might be contributory but it is not the cause nor source. First, we have already heard from those who've had their truck pulled apart, the ceiling panel properly secured to the crossbars all to no affect on the problem. Second, based upon the description of the problem and the affect on some of the occupants, the roof panel would have to have rather significant movement with a large amount of energy behind that movement. If that were the case, you'd hear the higher frequency rattle, or banging, of the roof panel against the crossbars. That is not being heard which is saying the panel is not moving that fraction of an inch to create a rattle...if it is not moving a fraction of an inch, it is not creating the buffet.

MAYBE YES, MAYBE NO ? While I do agree with you that "IF" the crossbars came apart, you would think you'd hear a rattle of some degree. BUT interior acoustics are very tricky. Per the service bulletin they are to measure the gap inbetween the headliner and roof, correct? I could see where this MAY BE a factor.

Has anyone else noticed even over bump or rough roads it sounds "hollow" or like yours in a tunnel. I really think the tires are playing into this. ????

At this point, I just want my down payment and the one payment we've made returned. Like to get one maybe next year when they get all this figured out.
