What is the chance that GM would fix the vibration/buffeting issue in 2017 models?

[Blueinterceptor]

Is it possibly due to the redesign of roof lines where the doors meet. Weather stripping maybe doesn't provide enough seal. The hinges don't offer enough support. Wind gets between the two causing a vibration.

I suppose this could cause it but I'm guessing the wind noise would be unbearable and very obvious if this were the case. It's pretty much isolated to the design whether it's chassis, body mounts, airflow related, etc. Our Yukon was super quiet in cabin when we dealt with our cabin pressure/buffeting. There's a major flaw in design when tires balanced outside of 15lbs road force cause the problem. I am just happy we were able to eliminate 95% of the problem with new ties with multiple RF balancing. I was scheduled to have our headliner ripped out and roof (re)attached but decided against it after going the tire route first.

I suspect your roof bows came undone as you drove the car, nothing you could have predicted from the test drive

IIRC GM has "pulled" the roof fix, as it was coming undone again and think they have given up

They will likely deal with this on an individual basis until the next full redesign

Roof bows are still an issue with the 2016s?

I have a new 2016 Tahoe with a vibration issue and they tell me the specs are an acceptable level for GM. They are not acceptable to me.

 

[Deuce16GMCs]

Is the booming at low speeds when you hit every imperfection in the road pretty consistent on every Yukon/Suburban?

At least those with 22s?

I had a 2015 Suburban loaner while the Yukons tires were being balanced 17 times. And that booming hitting bumps at low speed from 0-40 mph?

I'm in the market for a 16 Denali, and have a dealer anxious to sell me one at about 16% MSRP. Howver, I'm a bit scared after reading this thread.

Is there any Youtube videos or anything of this? I have an idea what to look for. Folks that have it, do you regret your purchase, or are you dealing with it?

Thanks!

Does it have 22s? Drive slowly around rough gravel roads just broken up roads or road with joints. Drive slowly 20 -40 you hear booming like a speaker with bass in the cabin at every bump? That's booming.


Take it for a drive fror a drive on the highway. Turn off the radio turn down the A/C, if you can avoid road noise like driving next to a semi, thats great too. But just normal quiet no radio driving.

You should hear it woo woo woo woo sound that sounds the same as the rear windows down. Put ONLY the back windows down at highway speed and you'll know what your looking for. Niw put the back windows back up. And drive quietly, do you hear the buffeting. It's mots common at 70-72.

Now get up to 74-80, does the trick vibrate? Does the steering wheel shimmy. Do the passenger seats and DVD shake back and forth. You have the famous vibration.

If you dont have any of that, buy it. But beware, I drove 7, bought the one without, and it all developed after 500 miles.

Lastly, the bulk of these issues seem to be associated with pre 07/2016 build dates. Check the build date on the driver's side door jamb.

Last thing you need is to buy a brand new truck that was built 9 months ago and has been sitting on the lot rotting.

This is the best advice

IIRC drove 10-12 of them, found 2 that were acceptable, which means faint booming but absolutely no vibrations

I'm 100% convinced every single one booms, but not everyone can perceive it - and as the roof bows come unattached, the booms get worse

Not every one vibrates - run far away from any that vibrate, you should feel it at 35-50 and/or 65-80

As long as they have the silly third row seats that do NOT fold flush with the floor, I won't buy one anyway. IMO, GM has ruined the Suburban.

 

[mlgreen]

So are the ones with the main buffeting/vibration issues the long base models and ones with 22 inch wheels?

 

[BobDobalina]

Had a 15 Tahoe built in Feb 14 and now a 16 Yukon built May 16. Neither has any vibes at any speeds, no "booming" no "buffeting". The Tahoe was on 18s with stock tires and Revos later. Yukon is on 20s. Both have some creaking in center console area. Fixed it in the Tahoe with silicone spray. Not got around to Yukon yet.

I'll take that minor glitch over having to pull the damn seats out every time when needing the extra space. Maybe the XL is different, but honestly, the cargo area when seats down hasn't been an issue for us... you almost need to use a level to see that they aren't 100% flush. There are a few issues with new design but there's really no comparison to the previous models....they were so dated and overdue for a change.

 

[Ralph Varick]

no fix buy it back..........They keep producing trucks with same problem....Wake up GM

Sorry the third row seats do not work for me. Traded my 2008 on a low mileage 2013 xl. Nice vehicle and love the 6 speed transmission vs the 08s 4 speed. Hopefully GM will do something different about the seats by the time I need a new one. Also hope they quickly fix the other problems.

I had 3 problems: buffeting, booming and vibrating.

The buffeting is 100% related to out-of-round tires as AJS pointed out. When they got all 4 under 15lbs, the buffeting went away. I few weeks later, I put my new snow shoes on and it returned, albeit less severe. Got all 4 to 12lbs or better and it went away again. Likely not the root cause, but at least I have control over the inputs. [My roof was pulled apart and found to be fine, BTW.]

The booming was fixed by installing dampers on the exhaust system. The engineer working on my truck did not provide part numbers but I did post some pictures on the gm-trucks forum if anyone is interested. This was fixed on a separate visit than the buffeting and that's why I know the two are not related.

The vibrating was fixed with a complete rear axle replacement.

I'll still get the occasional hint of buffeting, especially with the Continental LX20s which are going to be replaced with Michelins. I'll only use LT tires going forward. I'm running on 20s for both summer and winter.

 

[adrone]

All I can say is my 2016 LTZ has 22" rims and it came with Bridgestone Duelers. I have no way to verify this but two separate tire shops showed me the tires are labeled as a "spec" tire. Meaning it is a cheaper lower quality tire than a standard Bridgestone Dueler. Made cheap for Chevy but they are still using the Dueler name....Nice deception in the interest of being cheap there on Chevys part. Real high ethics to do something like that to hundreds of thousands of customers.
That being said my Tahoe has a vibration issue. After going to a tire shop and using a road force balancer my tires came out at 37lb, 35lb, 12lb, and 6lbs. Basically my Tahoe came with one good tire, one ok tire, and two tires that cant even be balanced. This is probably the issue with Most of the new Tahoes. Funny part is that Chevy actually sent the dealer an order not to even check the balance of my tires....After less than 3k miles...Even after I had been complaining about it to the dealer since Mile 1. I even complained on the test drive....They told me it was flat spots from sitting and it would correct itself in a few hundred miles....lol.
What do you expect when you only spend 70k on a new vehicle though????
Guys I hate it but the truth is that Chevrolet has become a dishonest and unethical corporation. It would appear their business model now involves mass scale denial, attempts to manipulate and deceive customers, and profit at all cost with ethics and integrity thrown out of the equation. When I see behavior from Chevrolet that counters this I will be the first one to give them credit for it but that has not happened with this extremely unhappy customer.

 

[Rodbuster]

This may be OT, so apologies in advance. I have been looking for a vehicle to replace my '02 Avalanche. After reading the horror stories concerning the Yukons, Tahoes, etc, I feel that there is no way that I could purchase one. We took a new Tahoe for a ride, and to be blunt, thought it rode more like a "lumber wagon", than anything else. My Avalanche rode better!

And further investigation showed that Consumer Reports placed the Escalade at the very bottom of their customer survey rating, with the Tahoe and Yukon slightly above it.

I have been a GM truck man for years, but at this time, I do not feel that I would have confidence in one of their products.

 

[Illnasty]

Same as many of you other folk...2016 Denali and NO buffeting noise. The sunroof design sucks as it sounds like there a Boeing 747 five above you though when it's open

 

[Cha0s13]

I agree, that net mesh for the wind deflector sucks!!!!!
