Denali Buffeting Noise

[Plimbob]

Good Morning,

I am looking at upgrading from my 07 Tahoe to a 15 or 16 Denali. I looked through some of the threads but I couldn't find the exact year the buffeting noise was the problem?

Thanks,
Tim

Zero buffeting in my 2015 Denali. My friends have a 2016 LTZ and zero buffeting. I think a good test drive is more important than the year model.

p.s. I went from a 2012 Tahoe to the 2015 Denali and could not be happier with my purchase.

General trend was earlier model years more than later model years and even then it was vehicle to vehicle.

As Phil stated, you just need to drive each vehicle and see if it has it.

It’s all years. Test drive for a good long while.

Look for booming between 20-40 and buffetting at 75+

Is it also the same models years of Tahoes as well?

Yes but only a very small sprinkling have that issue. I have yet to come across anyone out on the road that has this issue as I talk to a lot of Yukon-Tahoe owners all the time from Miami-NYC which is at least 3 times a year via I-95.

Just take the vehicle on a long test run. Make sure you get ALL service records and have a good independent mechanic check it out on the rack from top to bottom. I would only buy from a Chevrolet-GMC dealer [that has good service reviews] but that is just me.

And to add to this subject there has been many, many discussions on this subject. It seems that a problem does exist on some but compare this to how many have been manufactured. The most common denominator is that some people are just more susceptible and sensitive to this issue.

It’s a major issue that has been covered thoroughly in the automotive press and has multiple Facebook groups as well as TSB’s associated with it.

Not to mention class action lawsuits.

Exactly. The moms I know that drive them are completely oblivious to it and never get them over 75 anyway lol

It’s very similar to the sound of vehicle makes when you’re going down the highway and somebody cracks a single window in the back. It’s really just the ‘sonic feeling/thumping’ that goes along with that not the roaring sound.

16 Denali short bus without the issue.

the exact year the buffeting noise was the problem

years '15 thru '20


it seems very hit or miss. & GM has no clue how to fix it.

to me it seems more of a tolerance stacking type issue... so 1 or more of the items discussed in multiple threads here could be fix when tied together


as already mentioned , go test drive &
make sure to try as many road types as possible & speeds btwn 25-75 (or so)

good idea to bring some other folks w/ you. as some have more sensitive ears than others.

A larger power amplifier on your audio system will help fix the issue, as well.

Gents,

I now am going to shift gears on you a bit, what is the ride & drive differences if you are comparing a 2017 Tahoe LT to 2016 Yukon SLT both with the 5.3L and neither have tow package so I assume the same gearing but I have gotten that deep. I am wondering about ride, cabin noise and general driving pleasure.

I do pull a 19' fishing boat at times (not as much as I would like) and general round town and short (< 500 mile) highway trips.

Your thoughts and experience is much appreciated.
Thanks,
Tim

Virtually no difference. Only in the Denali which has adjustable ride.

 

[Miami-Dade]

2016 Tahoe LT [82K miles] without the issue.

Never had this issue in my Tahoe or Yukon. Drive the one you want before you buy.
