ajs, there is a TSB for the rough ride if equipped with the magnetic ride suspension. My Suburban LTZ had the same issue and following the TSB my dealer replaced some of the suspension components (shocks and struts I think). It made a significant difference in the harshness over bumps. Yes, the feel is more disconnected from the road but it's a land yacht, not a sports car, so it works for me. Mine is a 2015i, and I was told the updated parts are standard on the 2016 models.

I am aware of this TSB but I have an SLT so no Mag suspension. Not sure if there's a revised shock setup for the early 15s or not.

 

I don't know if this has anything to do with the vibration but my dealer had to order a Ring and Pinion kit for the rear end. I find this crazy at 30k miles for an all stock truck. It's not horrible but there is a good whine at certain speeds. When I return and have the ring and pinion work done I am going to have them check the drivetrain for the vibration issue. I've ruled out the wheel tires myself so hopefully they can quickly determine if it's an axle, shaft or gear issue causing it.

UPDATE .....

OK that's my story today with my Yukon 2015 with 7000 km.. i went to my dealer told hem that i have vibration / and buffeting sound > they send the engineer to test it and he notes the problem ( good start :driving: ) >

i shows them the GM document ID :(4204876) IT'S ALSO CALLED #PIT5429 . THEY wounder where i got it ...( from this great site :angel: ).they knew that i did change the tiers already and balance them ..so they said they gonna change the propeller shaft immediately without doing ( Pico Oscilloscope )analyzer test . they order it and i wait a call when they get the part ..this was for vibration problem ..but for the buffeting sound they said this is from the roof bows need be resealing..

now am waiting for the part and will keep u update ..

but am wondering why they decided to fix it and order parts without testing the propeller shaft !!!! i hope that gonna help >> wish me luck guys >>>

I'm assuming you have a denali? I am very curious to hear if the propeller shaft fixes the vibration.

I've got a 2013 Acadia Denali which, though it has some specific radio/electrical issues, rides very smoothly. My lease is up this summer so I've been looking at the '16 Yukon Denali.

 

Given that I've no interest in a sunroof or rear entertainment (but would like a couple of other options), I would need to special order - the dealer I visited today indicated it would be about 6 weeks to get one built/delivered. They were able to put it into their system today for transmission on Monday - though I'm not committed and have signed nothing.

 

They only had one on the lot to test drive ('15 - 2 WD w/20" wheels). I just took it around town but noticed a slight vibration in the steering wheel around something like 40-45 mph, though I did not go much faster with it. That one also had a delay/lag in pressing the gas pedal and getting going. I didn't think much of it, but wanted to try another just to see if there was a difference. The salesman (well seasoned) just said that it's been on the lot for months and might need the tires balanced, but it's been my experience that an out of balance tire usually has a sense of more amplitude and lower frequency from what I was seeing with this vehicle.

 

They just got in a '16 4WD w/22" wheels. I took it along the same path and noticed a very similar vibration - almost like a slow "buzz" feeling in the steering wheel. I could even see the wheel vibrating slightly (nothing major). My wife said that she felt it too, but she's just interested in getting the additional passenger space in this vehicle over the Acadia... since it was noticably more confined feeling than our previous vehicle (Armada). When I said something to the salesman about the similar vibration he commented that the roads around there were not in the best shape. I did notice that this vehicle had better pedal response.

 

When we left I noticed that the same stretches of road felt smooth in our Acadia, with the exception of the actual bumps and seams in the road which I could actually see!

 

I've only read a couple pages of this thread, but wonder if what I've just experienced is part of the reported issues that all of you are discussing.

 

If next month, when the vehicle arrives, I take it for a test drive and feel this vibration - they'll just have to sell it to someone else.

 

Thoughts on this??

The most important piece of information for you to consider is what happened when you got out of the brand new Yukon and into your "old" Acadia... You went from harsh, noisy/boomy, buzzy, to smooth and quiet, right? All the new platform full size GM trucks/SUVs suffer from some kind of inherent characteristic which results in each and every vibration and bump in the round being felt and/or heard. There is no doubt on that. This forum, the pickup thread, several articles in the media....pretty much the way it is. If you want to avoid getting sucked down this vortex, don't buy one. If you want to risk numerous trips to the dealership, with no result, then I guess you could take the chance. But the odds are significantly against you if you do.

 

Personally, my wife lives the vehicle and the size. We have a Yukon XL. I wouldn't waste the time and money on the shorter version, as it barely has more room than many other SUVs, and the others don't come with all the noise and vibration headaches! But if you want the biggest there is, the XL can't be beat. And, with 20" Blizzack winter tires, it's quite smooth and quiet. So much, that I am dreading putting the factory 22's back on!

 

Good luck.

Believe it or not, the shorty actually has *less* interior volume than the lambda triplets (Enclave, Acadia, Traverse).

 

For my family, the layout is better than the Enclave now that I have a second row bench and shoulder room to sit 3 adults in it. I have regretted not getting the XL only a few times.

 

Back to your dilemma, I also recommend that you proceed only of you have a great service department that is willing to pull out all the stops for you. I'm one of the fortunate few that had my buffeting, booming and vibrating fixed.

 

If you do go ahead with it, negotiate a set of Michelin's with it!

I too did not find what I wanted on the dealers lot so I ordered and then found this site. I live on a ranch where 4 wheel drive is actually needed. I also drive from California t Oregon and back, 600 miles each way. The 20" and 22" tires are plain stupid on a car like this and if you leave the pavement. They are meant for sports cars who's owners expect to "feel" the road. The small sidewalls of these tires cannot handle the +7,000lbs of truck they need to carry. For this reason, I ordered a Suburban LT with 18" wheels, rear bucket seats and only the gizmos that I wanted (no jumbo entertainment for every seat and no sun roof). I have 6,000 miles of city, highway and off road use and this is the best car I have ever owned. The safety features alone are amazing: side alert, adaptive cruise control, lane assist, automatic dim/high beam headlights . . . I will say the ride is stiffer than my 2001 Suburban and the seats are a little smaller and firmer, but this car is very nice. Don't put rubber band size tires on a truck, they don't work. By the way, I bought mine through the local Costco, got a nice deal and $750 Costco credit. Also, before I bought, I took the TSB that is mentioned in this list, to the dealer and asked about it. He said he knew and would be willing to fix if needed or talk about a trade if needed. Of course he wanted the sale, but I had him sign a note saying he agreed to this. I hope you enjoy yours as much as I enjoy mine.

lowered a few of these rigs so far including my 2016 escalade. my customers said it help a lot with vibration. I have a feeling the stock stance of these suvs causes air turbulance around vehicles at stock ride height which is amplified inside.

Your customers confirmed they still have a vibration, so I don't agree with your analogy of the stock ride height cause there are three prior generations that were just as high. I tell you what, I would never set-up my truck like that, but I sure give you kudos for looks. You did a good job with that Escalade.

Staying with the kid theme, I would agree with the power of suggestion if a person is an inexperienced, first time driver who hasn’t experienced characteristics of a vehicle. But these comments appear to be from mature drivers and there is no way a mature driver would not notice shaking and vibration in this truck and not have experienced a non-shaking and vibrating vehicle in their lifetime. Although my truck is an anomaly, I believe these folks are straight-up with their complaints, some of these trucks are just not on point.

"~ But these comments appear to be from mature drivers~". Really? Read some of the posts on this thread.

no they do not the vibration is almost gone. One even went to the dealer and they confirmed it with the tool they put inside the truck and stewart chevrolet sent this into gm since gm wanted to see readings. The rear of these trucks sit much higher then previous generations. Also gm lengthened the rear lower control arms so there are difference. I lowered a lot of these trucks current and previous generation. Some customers say they have no vibration while others notice it and after lowering they said the noise pressure is gone while the vibration is barly noticeable its actually pretty drastic. My truck is slammed to the fullest and I have NO vibration at all. The trucks where they siad its almost gone are only at the 4.5 option of my drop kit so me being 1.5 lower just tells me its a airflow turbulence issue. The truck handle SO MUCH better also when lowered its just a win situation. Mine is a 3/6 drop

 

also on my truck i did front/rear swaybars along with shorter endlinks both front and rear MAJORRRR difference. Now we know gm wont lower these rigs but so far ALL THE THINGS THEY HAVE TRIED failed and I feel the design these trucks have is the killer. Well at least those customers that lower them will be happy

 

stock front links vs the new ones i install in customers trucks. Swaybar angle fixed and better cornering since bar is no parallel with ground

Point taken with content of some posts, but I was using mature as time behind wheel.

    • 286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔           
    • hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you  
    • Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.
    • Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
