The RF tire thing might be a band-aid but I must say ever since dropping down to the 20s and having quality tires installed with all numbers below 15RF, the truck is buffeting free. This is coming from someone that couldn't ride more than 15min in the truck before getting headache and sick feeling due to the horrible pressure/noise. And I was only days away from taking a substantial loss and trading in on a '14 Denali. I am not certain it will stay this way but 6k miles to date and still satisfied. The funny thing is, I am almost positive one or more roof bows are not attached as there seems to be way too much free play in sheet metal tapping roof but at this point I'm not having them touch the roof.

 

Regardless, these trucks are way too sensitive and I'm sure multiple items can cause the issue.

How far in the 20s someone recommended 33

ANYONE ELSE HEARING LIKE A BUFFERING SOUND? MAKES YOUR EARS FEEL LIKE THE WINDOW IS DOWN, BUT IT IS NOT? I TOOK IT BACK TO THE DEALER, THEY HEARD IT. WE GOT IN ANOTHER 2015 YUKON XL AND HEARD THE

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

I recently purchased a 2015 Tahoe PPV and have the cabin noise issue as well as road vibration at higher speeds. I bought this in Ohio and live in Texas and am being routed through the normal channels (Take it to the closest dealer, let them troubleshoot, blah blah blah). Is there ONE instance where someone has had this issue resolved completely? I am distraught at thinking about having my Tahoe in and out of the shop, ripped and torn to shreds only to have the issues still exist.

 

Is there any hope?

OK ,

hi every one .

UPDATE......

I just got a call from my dealer to try my car after they change the propeller shaft. and resealed the roof bows . it took so long cuz the part delayed . any way i tried it and i was shocked it's a huge different NO vibration at all i went until 135 km .

and for buffeting sound they found one of the three bows is unattached the front one but they did them all , to be honest the sound i think is still there but it's much better 90%.

am glad that they could fix some thing finally i will drive without shaking :driving: .

​and here i want to say something that i was so nervous wen they told my the procedure for the roof and how they will tear every thing down i expect it ganna be mass but it was the conversely it was so clean and professional.

i wish u luck guys .

 

 

 

 

 

am sorry guys i was wrong .!!!!!!

i tested my car for two days straight on high speed road and i found the problem still present .after all what they done for two weeks long :-( i just took it back to the "dealer " and they told me they ganna balance ties again lets see what they can do ??

i know on thing that the company all they do is give customers "Tylenol " to stay silent .what a shame

My vehicle is built and on the train (Arlington to Jacksonville), so it should be in by the middle of next week.

 

I'll be taking it for an extensive test drive before signing anything. Just to make sure I'm paying attention to all the right things, please let me know if the following is what I'm looking for (and hoping not to find):

 

> Vibration at mid speeds (35-50)

 

> Noise at highway speed. Someone described it as the odd sound when a single rear window is open - choppy.

 

Is that about it?? I only want this vehicle if it does not start with issues.

 

THANKS

Is that about it?

One week before arrival, you still have enough time to peel back this thread and read about pressure, buffeting, and droning before your test drive. You will also find in this thread that some issues didn't begin until a few thousand miles later.

Lift - I was referring to the size of wheels (20s) not air pressure. I had the oem22s at one point but when I ordered new michelin tires, I changed them out to the oem denali 20s. I also lowered psi to around 33psi and that has improved the harsh ride to some degree.

Someone Let me know if I'm right about this

1 Rear end and tires contribute to the vibration

2 Exhaust dampers are related to the booming

What's related to the ear pressure?

 

Has the pressure problem disappeared with the correction of the vibration or is that a separate issue.

Is that related to the feeling or sound like the back windows open. Jus trying to figure out what to look for while shopping

Speaking from my own experiences...

 

buffeting [ear pressure] --> tires [i'm certain of this and you can read my previous posts in this thread why]

vibrating --> rear end

booming --> exhaust dampers

Did you change the bridge stones or jus balance them. Found one without the booming or vibrating but did exhibit a lil ear pressure

My Denali had the stock 20" wheels with standard issue Continentals. It took *6* replacements before they could road force balance them all to 15# or less. That was the day that buffeting/pressure disappeared.

 

When I put my winter shoes on [bFG KO2s mounted on 20" GMC AT wheels], the buffeting returned, albeit less severe [the worst one had a 18# RF]. I went back to my tire dealer who spent about an hour road force balancing them. 2 had to be replaced and they're all under 12#. No more buffeting! My Continentals are back on and the Yukon is quiet.

 

If I were buying one off a lot, I'd negotiate a set of Michelin in and demand that they're RF balanced to 15# or less. As soon my Continentals even look at me in the wrong way, they'll be replaced with Michelins. Likely the "Michelin Premier LTX" as I only need 3 season duty.

 

40mph and 70mph were the buffeting sweat spots in both my Yukon and the 2015i Suburban rental I had.

Not permanently. Mine took about 2k miles to show up. After being fixed it probably took another few thousand miles to return.

 

I will say the the Dynamat applied by my dealer to the roof cured the booming especially that associate with the V4 mode. All of the extra foam/glue has reduced the buffeting even after the rearward bows have come detached, but in the end, the roof won't stay attached so be it vibrating car parts or non-smooth road surfaces, the truck will buffet.

 

If you have a vibration issue, that will need to be addressed regardless since unbalanced spinning parts will be a problem unto themselves.

 

Has there been ANYONE that has had these issues completely resolved

      OCI, not when but why?

      By KARNUT · Posted

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      By ShotgunZ71 · Posted

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.
