Wow, I was just re-watching tonight on my home PC (which has a subwoofer) and I can absolutely hear the body booming in your first video. Turn up the bass and listen...

I can't find my GoPro... Will keep looking. I probably brought on one of my last 4X4 trips, didn't use it, and tucked it away somewhere.

Almost pulled trigger on '16 Suburban z71 yesterday, but this issue giving me pause. Tough to believe GM cannot come up with a solid resolution given the number of months this issues been out there and the number of affected units they must have access to through buy backs and dealer inventory. If it takes more than a production line tweak I wonder how long we will have to wait for a fix. Would be nice to know what percentage of units are affected...

BuyAmerican,

I am one of the people who back in August of 2015 ordered a 2016 Suburban and then found this group. While waiting for the car to arrive I talked with the salesperson at my dealership and they agreed to let me take the car on an extensive test drive when it arrived. After reading these posts and copying the various technical bulletins about the problem told the dealer that if the car had any of the buffeting or vibration issues I would not purchase the car and if those issues turned up later I wanted a record showing that I was concerned about it at purchase time. I also spoke with the service manager about the issue and he said he had seen the problem and produced the same service bulletin that I had. He explained what we all have read on this forum, that there is a problem and there are various ways to address the problem. He said while there are problem vehicles the vast majority do not have the buffeting and vibration issues. I was very skeptical.

The 2016 Chevy Suburban LT with roof rack, middle bucket seats and 18" wheels that I received has been a joy to drive. So, there are a few good cars out there. My suggestion would be to be upfront with the dealer and let them know you are well aware of these issues and take an extended test drive with or without the sales person and another person with "young ears" that would recognize the buffeting and vibration issues. My wife is very sensitive to such things and after our hour long test drive around the San Francisco Bay Area highways, city streets and back roads she felt the suburban road and sounded fine.

Bottom line, be up front with the dealer, do your homework and take an extensive test drive on THE car you plan to purchase.

(PS, I monitor this list and the Facebook page just in case my Suburban starts developing these issues, to date I have driven a little over 3000 miles to and from Oregon, through San Francisco, in the snow and dirt roads. The vehicle is more firm than my 2002 Suburban but I like that feeling of steadiness . . . and the safety features are far superior.)

Thanks for the input Willyspu. It is a concern that more than a few people have said their issue did not appear until after a few thousand miles of driving. Tough to root that out on a thorough test drive. There is some risk with any new vehicle, and I do believe you see a disproportionate concentration of negative feedback on the internet. It is probably safe to assume the majority of suburban owners have not had any problems. I'm glad to hear you are in that category. Does yours have a sunroof?

No Sun roof because eventually they all leak.

Agreed, my last 4 GM's with sunroofs have all leaked at some point. Nothings perfect lol..

"Rare." Funniest quote from this story. Hard to believe that 6 people he spoke with don't have either issue. Let's remember this is in Detroit.....

Not answering the rare piece, but it’s not that hard to believe a truck does not have any shaking or vibration. I have been driving mine since Feb 14 and my truck has never shook or vibrated. But I will disagree with GM, I do believe this is a safety issue.

Sheet metal provides a level of protection, this problem jeopardizes the integrity of the vehicle and should be determined a safety issue by GM. Sheet metal separation seems like a big fix which will include possibly welding, sanding, painting and interior carpentry work. I think GM conducted R&D on the problem but hoped customers wouldn't notice until they could fix the problem on subsequent models.

I wouldn't consider it a safety issue either, at least in my case. It's just annoying as hell. I don't enjoy driving my Yukon because of the buffeting.

I wish I could park a buffeting version and a quiet version side by side and compare them. This must be a solvable problem!

Does anyone know how to measure vibration/movement of the hatch while the car is moving at 40mph and 70mph? Chaser car with a good camera? ;) GoPro suction cup?

I have the setup for this and would be glad to test it out. Let's determine what would be best to see and then I'll get on it. I could also do a video on my roof as well. FYI, I have a SWB Yukon Denali until my REAL Yukon Denali comes in.

Well....good news and bad news. The good news is that I had a plan all laid out to get some serious footage from many different parts of the vehicle, put it all together in one video and see what you guys thought. The bad news is that as I started my second set of tests, my GoPro suction mount came......unsucked. Obliterated the suction cup and waterproof housing and dinged up my Hero 4 but it was laying face down in the road with no lens damage whatsoever. So....I'll re-up my equipment and give it another shot. Here is the first test. Honestly, there is nothing really to see here (which may be a good thing).

20 secs each at 40mph and 70mph (constant speed) of the rear window meeting the lift gate.

@Yahtzee: Thank you for taking the time to record, edit and publish this!

@everyone: I might be seeing something that isn't there, but does anyone see small movement of the glass? Watch the edge.

Fog, I did see it. Also go back to page 3 of this forum and read Speedvision's post about "Tailgate Seal Gap " 25 april 2015 And no response from anyone ? I think everyone is so hung up on roof,shocks,tires,wheels, exhaust,fenders,drive shafts, etc, as the problem. I think the problem is in the tailgate area. I do not know if there is any adjustment in the latch to tighten the hatch against the gasket ? Once again the bad car I test drove had the booming in the rear of the car, not over my head ,not under my seat, not under the tires, not around the shocks, not from the fenders or exhaust. Good luck. All the best, Booty

Emailed 3 of the 5 or 6 publications since they first started running the articles about the issues with the GM suv's and not one of them has either called or replied to my emails!

Here is a link to that post. I hadn't read that and will try the paper test.

Agreed that vibrations and buffeting are often confused. I had both [though the vibration was minor] and now I have only buffeting. The buffeting is eerily similar to what some Tesla and Porsche owners have experienced. Solved by adjusting their hatches.

I bought a roll of stretch film today, commonly used to wrap boxes for shipping. If the weather cooperates, I'm going to seal the entire hatch from the outside.

The fact that you found a non-buffeter and not all have one, give me hope that we're just an adjustment or rubber seal away from having a quiet vehicle.
