2017 Tahoe Premier noise in cabin same as others


Recommended Posts

I have been reading all the posts about noise in the cabin and the V4 buffeting. We had a 2016 Yukon SLT with all the booming/buffeting noises and had GM do the trade asssist. We then bought a 2017 Tahoe Premier, had the dealer take the 22" tires off as they were hard to steer and made noise. The dealer put on 20" and it made a big difference. The problem we have now is at low speeds and somewhat bumpy roads the booming in the cabin drives my wife crazy. I was following Fogduckers thread and he had weights added to his exhaust. I mentioned it to the dealer but he had no idea which to order and if it would work. We drove a Tahoe LT with 18" tires (same noise) then drove a GMC Denali 6.2 with noise cancellation (same noise). We only have 400 miles on it and the wife refuses to drive it and wants to get rid of it. We got rid of our 2007 Tahoe LT for this one. Can anyone help with this issue? I would like to try the exhaust dampeners if anyone has the right Part numbers.

Dealer said that RF doesn't apply to me as my problem happens at slow speeds and certain bumps. My wife said it was there at test drive but her ears are more sensitive than mine. Plus I was more interested in listening for the V4 mode to see if this 17 Tahoe had the buffeting (which it does not).

You still want to minimize all vibration inputs in the vehicle

 

I'd take it to an independent, it's probably $60-100 to get it done, can't hurt

I test drove two 2017 Tahoes and one Denali and nothing has changed. Buffeting and booming still exist. Not a chance in hell I am buying a 2017. Buffeting was brutal at 41 mph. Denali was so bad I turned back 15 minutes into the test drive with a headache. Here's hoping the 2018's are better...

Well got the RF done and one tire needed to be turned. GM said they would pay for the RF as a customer goodwill. Got the word from GM that my noise "booming" is normal and they will not do anymore with it. Makes me feel really good to spend $72K on a vehicle and get no respect. If someone out there can figure out what these junk SUV's need i would love an answer. My problem and your problem is considered normal so we all have to live with the awesome noises these junks make. I only have 500 miles on it. The next step for me is to get the Part number for the exhaust dampers, then I have to find out where the vibration is coming from. I guess I'm on my own to fix my problem. If and when I do GM will have to pay.

I am stunned that there's a part that fixes this booming and despite service departments demanding the part to repair the issue, GM still blatantly denies that there's nothing else they can do.

 

They dismantles the frame form the body and retorqued it, And RFB my tires from 28-38 lbs to to 12-18 lbs. This reduced my buffeting by 40%.

 

Next week they are replacing my 22s with 20s and replacing the Bridgestone with Michelins. This should get me RFB down to 10 lbs or lower and improve cushioning; hopefully eliminating the buffeting and vibrations.

 

Last;y, despite admitting that the dampers exist, they want to swap out the exhaust on my 6.2 with a new one BEFORE attempting the dampers. Crazy considering that the OEM exhaust is over $1500 and the dampers probably cost $50.

What does the buffeting feel/sound like?

Like being on an airplane. Less pressure but not normal for riding in a car. Unfortunately, my ears are sensitive to the pressure, so I get headaches almost daily. I was so happy to have a loaner Cruze last week. No headaches 5 straight days.

I can't remember if you stated in a different post if you were going to swap tires, but that would be the next step. We went through the same thing and ended up ordering new michelin tires (20") and made sure all were RF under 15lbs. It fixed 90% of the buffeting. The booming still exists on rough pavement at low speeds but we are going to live with it at this point. We've not attempted any repairs for the "booming." I still have the denali 22" wheels that I'm considering going back to with Michelin Defenders...currently running the denali 20" wheel with michelin LTX Premier.

It looks like one or two others had the "booming" fixed with the dampers/dampeners like I did nearly a year ago. Check out the last dozen or so posts in the "noise in cabin" thread.

 

@SilvgMc2017: Here is my description of the buffeting and booming.

 

Buffeting at speeds of ~65km/h and ~115km/h [40mph and 70mph]; not heard at speeds greater than 130km/h [80mph]; annoying as hell; sounds like driving with rear windows down [Helmholtz resonance]; sounds like double bass from a heavy metal band using a broken amplifier; 30-70Hz range; not all the time, but most of the time; some road surfaces, even smooth ones, seem to excite it more than others; can be heard more clearly when ear is facing rear of vehicle; fades in and out; happens with seats up, down or folded; more audible from front seats.

Single instances of "the boom" at low speeds over bumps [driveways, expansion joints...]; coincides when rear wheels go over the bump; sounds like somebody flicking a 12" subwoofer with their finger; doesn't always happen; slightly more difficult to hear; commonly heard on concrete borders between driveways/lots and roads; always noticeable on gravel or brick roads; seems to originate from rear of the vehicle

 

booming = exhaust dampers

buffeting = tires [it took 6 Continental replacements to eliminate mine; starting to come back after 20,000km; gone with BFG K02 winter shoes; running both on OEM 20s wheels; will replace Continentals with Michelin eventually, unsure which model at this point]

vibrating = rear axle [replaced]

 

As I've mentioned in various posts, I don't believe that the root cause of the buffeting is the tires, rather that something about our trucks is more sensitive to anything out of round. It's hard to believe that OEM tire manufacturers all started producing bad tires when the new K2XX platform hit the streets. I believe that the previous generation was simply less sensitive to less than optimally balanced tires.

 

The good news is that we can control the *inputs* to the buffeting and ultimately get a noise free vehicle. If the cost is a few extra RFB'ing sessions over the life of the truck, I'm OK with that.
