2015 YUKON NOISE IN CABIN

Techbrute · April 21, 2015

The Traverse/Acadia is a more apples to apples comparison to the Highlander than the Tahoe/Yukon. Front wheel drive unibody designs give you more interior space, with the downside being the duty level. If interior space is your main consideration, a minivan or crossover are actually better choices. We rely on a Honda Odyssey for the majority of people moving that we do. But, with a family of 6, taking the ATVs somewhere requires towing capacity north of 5K pounds, which is tough to find in a crossover. Most top out around 4K, it seems. Add in things like an integrated brake controller (or at the least, pre-wiring for it), self leveling suspension, and a standard hitch, the choice is clear.

Has anyone tried ANYTHING that has improved ANYTHING?

I strongly encourage everyone having this sound issue to back off a uneven surface at an angle. Let one of the wheels fully drop out to the shocks max out limit. Not slowly, but let it drop out rapidly.

LISTEN TO THE SOUND IT MAKES. I'm still betting everything this is a Syspension, low profile wheel/tire, overly stiff chassis issue.

Our awesome 2015 i goes back in to the shop this week for:

Headliner removal, re-glue foam and whatever they do.

New transmission. Replacing the clunker.

360 degree camera and software replacement and update.

Drivers seat TSB movement.

Exhaust system replacement. Faulty flapper valve.

Such a great car

Spoke with Service Manager at Liberty GMC here in Charlotte. I had left his a voice mail last week telling to get GM involved as I want out of my Yukon XL. Over a month in the shop since I bought it at end of October. I told him I do not want "trade assistance" for another GM product.

I'm not saying at this point I will never buy another GM vehicle. I've had numerous Suburban's, Tahoes and Yukon's over the years and they were good vehicles. But GN obviously got a major problem on their hands with the 2015's and I simply want out. I do not have the time to let GM experiment on my Yukon. I understand I have driven the vehicle for 6 months and I can accept some depreciation. I paid 72K out the door, of that about $67K was the cost before wheel upgrade, fees, taxes, etc etc. Kelly Blue Book is saying value is about 57K, so that is 10K depreciation in 6 months, which is excessive, considering my vehicle spent over a month in the shop during the 6 months I have owned it.

GM if you are listening, I would like a 60K refund for my 2015 4X4 Yukon. XL SLT. Let's make this quick and painless for all. Spring is my busy time for business traveling and I need to get another vehicle ASAP and hit the road and see some customers.

Jert1346,

You're skipping the Lemon-Law approach and I think that's a big mistake. My sense is GM long ago stopped volunteering buy-backs unless you caught the problem in the first few miles. And plenty of people have tried to explain to GM how they're a big Yukon/Suburban/GM fan, it won't work either. Same with the concern for the safety of your kids. They hear it all the time. Get to your state's info on Lemon-Law rights and start the process. GM will play dumb and count on you to give-up. If you just settle for a cheap trade-assistance package or sell it yourself then you are letting them off the hook and walking away from your investment. The process is not that difficult and you can recoup a lot more of your money. But you have to start the process, you cannot just threaten to.

Update on my situation.

Quick recap; same issue as everyone else (Suburban LTZ). Dealer says no buyback time after time.

I tracked down the District Manager of Aftersales in my area, and I now have some progress. (Guess what? They can force the Dealer's hand). They sent an engineer out, basically to confirm the problem. They're trying new struts and shocks as others have tried.

The kicker is, they are approaching 15 business days with our vehicle. So when this doesn't fix the problem, the car will officially be eligible under the Lemon Law.

They'll either be buying this vehicle back OR I'll get my money back through the Lemon Law Process.

We've had to make a BIG stink on this. I've written letters, made a ton of phone calls, complaints, etc. It's a shame we have to go through this, but DON'T GIVE UP, and as another user commented to me, 'walk with a big stick.' Keep all your documentation.

Good luck to everyone else. I'll keep updating.

Did they offer you a loaner? Check your State's Lemon Laws, as that may impact the number of days and/or eligibility.

Time for an update. Ours went to the dealer week before last because the fuel pump died. While it was there, they loosened all the body mounts, which I had them do the very first time I took it in to make sure the mounts were neutralized (in their neutral position). Didn't make any difference that time, but this time, they actually took the vehicle out and drove it with the mounts loose, then torqued them back up. Guess what....it made a difference. Now, don't get excited, problem not solved. Still booms like crazy over all bumps, big or small, at all speeds, slow or fast. But, the buffeting and pressure are pretty much gone at highway speeds. I say pretty much because rough road/bumps at highway speed will induce the buffeting, but there doesn't seem to be much pressure. At least not like before. And we've been driving it for over a week and it's been pretty much consistent.

The point? The body mounts are part of the problem. Or at least, are indicative of the transfer path involved in the problem of buffeting and pressure. At least we really don't suffer from the pressure driving down the highway now, so it's tolerable while GM continues to work on it.

I still maintain the vehicle seems to have a heightened sensitivity to any and all forces that "jar" the body, so at the end of the day trying to remove those is futile. There will always be bumps in the road, and the tires will always degrade slightly. The real solution is to de-tune the thing that is vibrating/resonating, whatever it is. And I haven't zeroed in on that....yet!

Wrench: thanks for the update.

Ours is back at the dealership as well. GM is insisting on doing the headliner removal thing. (Rolling my eyes) they are also doing the TSB on the drivers seat. 360 degree camera replacement and software update, replace the exhaust system, has a Chirping defective flapper valve. And new updated transmission.

Been in two loaners during this service visit. First was a 2015 Suburban. Had the roughest idle issue ever and yes it was a BOOMER over the bumps like all the others. In a 2015 black Tahoe right now. Thing looks incredible really good looking truck. But it's absolutely the worst booming 2015 SUV I've been in yet. It is 10 times worse than our 2015 Yukon we owned, it's worse than every other 2015 Yukon, suburban, Escalade, or Danelli that I've driven since September. And I tell you the number is countless amount of vehicles I've driven to check on this condition.

All I can say is I sure wish it was another vehicle that suited are families needs. Something that would had a room for seven or eight people, that had the capacity to pull a decent size boat, and had decent looks. The looks of the new Infiniti is starting to grow on me, i've never gone and driven one but I hear they're absolutely incredible inside as well. It seems like there's 15 new ones at our kids school at drop off every morning. Might have to go drive one, dealing with the GM sound buffeting / BOOMING problem is getting really really really really old . Have to be honest, I feel really really really stupid for spending this kind of money on this piece of junk.

@TOBTEK:

Q80 Limited is my next new ride. I test drove one for a day. It was nice. Like you, the appearance of the 2015 GMC's are just great. It took me a while for the Infiniti to grow on me too. Take one for a ride...you can't help but like it. Especially if the dealer has a Limited.

I have no skin in this game, but I recently sold my 2013 Lincoln MKT for many reasons, this issue being one of them.

Has anyone checked to make sure the pressure relief flapper thingy is working properly underneath the rear bumper cover? I'm just assuming the GM vehicles have one on each side like my MKT did.

ateam_burb · May 8, 2015

@jeeps, that is interesting. Can you tell me what the flaps actually look like or post some pictures?

Good call. They tested that on my first one...everything came back normal with the flaps. That was one of the first things they tried. It was determined not to be the cause of the pressure.

Where are these "flaps" on these Chevy/GMC's?

Ordered a 2015 Yukon SLT in September. Delivered in December. Complained in January about road noise/rumble at 60-75 MPH. Changed tires. Changed differential gears. No improvement. Requested a 60K refund. Vehicle sat at the dealership for two weeks awaiting a field engineer to assess. No field assessment made; just a GM judgment that it was not a safety issue and therefore would not be refunding money.

A superb dealer is helping me minimize my loss.

Bought an Expedition. Better ride, handling and performance for less money.

As in the post above, I've had numerous Suburbans, Tahoes and Yukons over the years and was very pleased. This product edition is a huge disappointment, as is the GM response to a long term customer. Ms. Barra states she is trying to change the culture. She has a lot of work to do.
