My 2015 Yukon XL has been in the shop 4 separate times (3 separate GMC dealerships) for the buffeting noise for a total of 34 days in the shop. They have replaced the shocks, exhaust, drive shaft, tires and the last time they removed the headliner and re-glued the roof bows, ZERO improvement. Also when they removed the headliner they must have damaged the antenna because now I have no AM or FM stations and my phone will no longer sync. Have to put it back in the shop for those fixes. Also have dash warning saying side detection system needs service.

 

Sorry this sucks

 

Seems like a prime candidate to start the lemon law process in your state

I've had my 2015 Yukon XL back for 1 day after it was in the shop for over 3 weeks (this time). The buffeting is the exact same, with no improvement whatsoever. I am having 500 cheap business cards p

Hi all,   I created an online survey to better quantify the issues surrounding our trucks. The goal is to get more accurate numbers. The survey is open to *everyone*, including those with no vibra

Have you checked yourself to see if the roof bows are actually attached? It's easy to do and I'd say better than just taking their word for it.

 

Just to clarify my points. In engineering we describe these issues with forcing functions (differential equations). On one side you have the disturbance (unbalanced tires, drive shafts, bad diffs, rough roads, whatever). On the other have the disturbed, (truck or a part of the truck). Fixing tires helps the forcing side of the function and if you have unbalanced tires, etc... that is an identifiable issue that should be fixed so you don't FEEL the vibrations. However, if you are HEARING the vibrations or feeling them in your ear drums (buffeting is often below the hearing threshold so you more feel it warping your eardrums than hear it), then you have issues with the truck side of things that need to be addressed. You could have issues on both sides or only one. If you have truck that booms, buffets and speed, and drones, you likely at least have detached roof bows that are resonating due to any input being wind vortices at speed or unbalanced components. If you just have vibration issues with no buffeting you probably just have unbalanced spinning stuff.

 

At the end of the day I don't think these issues will be all wrapped up in one component, however, I would stress that it is important the vehicle not require unicorn grade car parts not to buffet and boom. It has to have some tolerance of irregularities because nothing is perfect. If your dealer is flailing while only replacing parts they should probably be redirected to look at the truck's body structures.

 

At the end of the day dealers cannot engineer vehicles, only repair them. Appreciate that they are likely going to through a lot of trial and error in some cases to fix the truck. If they are competent, I see no reason they cannot eventually fix the truck. Patience is required on our part if we can afford it. Some of us can't do that due to things beyond our control but that is the reality.

Well written. All makes sense. Fix roof-eliminate pressure. Address balancing- eliminate vibrations

Forcing functions. I just had a flashback to my systems dynamics class from junior year...nearly two decades ago. Ugh.

 

Anyway, my Yukon has been at the dealer for 3 days now for the roof bow fix. I was told it would take 2, now we're heading towards 4. I hope this is just because the body shop got backed up and decided to take their time, and not because the fix didn't work.

 

Still keeping my fingers crossed.

have you been in the loop on the fix? Are they installing dynamat as well as making sure all bows are stiffened up? Did you share any additional info with them or are they just following the TSB? What size wheels are you running?

I gave them the contact info for Frank's dealer and asked them to call to review their process. I am doubting they called, though. According to the service manager this was the first issue they have had with this, so they sent it to a local body shop for the work.

 

It's all a little loose for my taste. If it doesn't work, I will be back in touch with GM (I have a case number), and we'll see where it goes. This whole thing is just giving me a headache...from the pressure when I drive that car, and from the stress and frustration dealing with this.

I hear ya...My dealer has never dealt with it either and sent me to their body shop as well. I am planning to provide the body shop "handouts" when I drop it off to them.

Hi all. New to the site and saw this.

 

I'm currently shopping for a 16 Denali XL since I need the space for my 2 big dogs, and 4 yo girls, plus space for luggage. I haven't read all the posts, but is this buffeting issue more prevalant on sunroof models?

Negative. Sunroofs are not a factor.

Well, it looks like at least one automobile publication is going to be writing a story about these issues. I just got word that the news editor for a auto rag (can't say just yet) is "finalizing his story on the SUV issues" and asked for more information. I hope this is the bump we need to get GM to get off of their ass and do something. I will keep you all posted.

 

UPDATE: I spoke to Stephen Elmer, News Editor for Autoguide.com, this morning. They are days away from publishing a piece on our issues. He is now on these forums and has reviewed a lot (not sure if he hit all 98 pages). GM has provided comments back to him basically stating that a PI was issued for the buffeting and that should have fixed it. It obviously hasn't. Regarding the larger vibration issue, dealers are obviously trying all types of things none of which are really working. We are trying to get more attention on this and this is a great start. I've asked him to chime in and ask any specific questions that he can include in his piece. This will hopefully get us closer to a fix.

 

Stephen, please quote this message as a starting point. Thanks.

Man this is all over the place. Wish we could establish what helped or didn't help and what needs to be corrected in that order

CI , I agree with you. Once again... My rear trunk hatch window is real tight against the seal. No problems. The first Yukon I test drove had wind problems AND a sloppy fitting rear trunk window. Hello ??? Please just Try to adjust the hinges and the latch by 1/16" to 1/8'' to "smash the glass tighter against the gasket and frame. No stupid Putty and glue on my new Yukon. I own a fleet of GM work vans and the roofs are glued to the ribs with a foam liner in the middle. No Problems on any vans. Rear windows are tight on all vans. Just want to help,,, I bought a Porsche 4 years ago and found the " 986 forum" After reading about a problem with an "IMS" bearing for 3 years , I got so down on the car and the uninformed forum idiots ,that I did not drive it. It stayed in the garage, covered, until I woke up and sold the car and quit looking at the "Forum". Come to find out the problem was not a problem if you serviced the car and did not "Race the hell" out of it. Good Grief !!! Just for your info.........All the best, Booty

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
