2015 YUKON NOISE IN CABIN

Don't know if I am following this, the Tahoe LS, LT and the Yukon are the least expensive GM Fullsize SUVs. But if anyone of those trucks were taken to the dealer and asked what could they mod, the only thing that would be a problem would probably be the 6.2 and the Mag Ride, everything else is pretty much plug and play. Which would make these trucks the same. If that's the case all should have ANC. If not, based on your test the least expensive models should therefore have crazy road and wind noise. I have a LT, my RPO code says my truck came with ANC and I have no road or wind noise.

What's interesting about the fact your LT has "ANC" is that based on the online specs and features, none of he Chevrolet models come with "Active Noise Cancellation". The term is not used anywhere for any of the models. And, doesn't show up as an option in the build section. Now, I realize the website isn't the final word, and the dealer system is different and will build it based on what GM will allow. But, in contrast, on the GMC website, "Active Noise Control" is only used in one place - as a standard feature in the Denali versions.

 

Now, both Chevy and GMC show that the 9 and 10 speaker Bose systems include the "AudioPilot" Noise Cancellation feature.

 

So the big question is - is there a difference between and vehicle with the Bose system c/w AudioPilot, and a vehicle also with "ANC"?? More importantly, does it matter? I say not. I drove a variety of rentals, with and without the Bose system, and all of them exhibited the buffeting. So, I'm pretty sure it's irrelevant. At least as a cause.

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

"My Yukon is a stock 2015i short Denali with the only option being the 2nd row bench. No sunroof. 20" wheels with Continentals. 6.2L/8-speed"

 

For the record, my daily driver is the same but with the sunroom and crossbars.

 

 

Do both of your trucks have factory crossbars...and neither have the buffeting issue? Have you been in one and have noticed the buffeting?

No crossbars on mine, but I will buy a pair by March.

 

Me: My Yukon is a stock 2015i short Denali with the only option being the 2nd row bench. No sunroof. No crossbars. 20" wheels with Continentals. 6.2L/8-speed. Buffets/vibrates/booms.

Note: In addition to the consumer magazines, each of you with this problem should submit your problem to BBB Autoline and the Federal Trade Commission (yes, they do want to know).

 

Let me add some input on this. GM/GMC has done several things in the past 18 months, which are unethical, and in some cases illegal. Two examples (most commonly found in this and other forums): (1) these vehicles have a problem with buffeting which has caused headaches, makes many unable to be in the vehicles, and caused symptoms of vestibular disorientation ... in the best case, discomfort and in the worst the disorientation, need to vomit, and severe headaches could be a distraction leading to an accident; and, (2) continuing to market the vehicles as having a lay flat cargo area which it is not, leading to items falling out of the vehicle when the tailgate is opened and, in one case, a heavy item falling out and causing personal injury. In both of these examples, GM/GMC has (a) acknowledged these issues, is continuing to advertise, market, and sell the vehicles without warning consumers of the potential problems; (b) has no solution to either problem; and (c ) is unwilling to take back vehicles with complete refunds to consumers or in many cases, simply doing nothing except perhaps offering a $250.00 to $1000.00 coupon to purchase accessories (for a vehicle you don't want to keep).

 

Unless GM/GMC starts getting pressure from BBB Autoline and the FTC, they have absolutely no incentive to fix the issues or, in some manner, compensate the owner, or replace the vehicle (no charge to owner).

 

My 2 cents only.

"Now, both Chevy and GMC show that the 9 and 10 speaker Bose systems include the "AudioPilot" Noise Cancellation feature. "

 

AudioPilot and ANC are two different beasts. Active Noise Cancellation (ANC) is an effort to reduce cabin noise and can only work effectively at low frequencies (a function of cabin size and seating area size). AudioPilot is an attempt (a poor one at that) by Bose to increase the intelligibility of (in particular, speech) sound from your radio/audio system. It measures cabin noises by frequency and then boosts those frequencies masked by cabin noise.It does not work across all bands and its effect is very difficult to discern...and difficult to detect without some rather sophisticated analysis equipment. Both were developed by Bose.

 

Magnetic Ride Control was developed by GM and can be found in the Audi R8 and Ferrari. Bose has also developed a much more sophisticated Magnetic suspension. There were rumors Bose and GM collaborated on the system use in the Yukon Denali and Escalade. Based upon performance, it would appear to be just that --- rumor. Also based upon performance it would appear to be the older single wire system rather than the two wire system on the Corvettes...I guessing on that however.

The gen 2 and 3 Chevy Fullsize SUVs did not come with ANC and did not have the buffeting and pressure. Then the new gen 4 comes along with higher and thinner metal panels, more hp, and performance car suspension. Some of which I believe allows for more cabin noise and pressure. GM knows about this from the onset and what do they do, incorporate ANC to manage the cabin noise and pressure. I agree ANC is not the "cause", but I believe it was put in the new gen 4 trucks to be part of the "solution".

What did you get ?

Went back to a pickup. 1/2 ton Silverado. I do a fair amount of towing and the booming sound seemed to be amplified with a trailer attached.

Looks like I'll be doing the same with our 15 xl slt...I may test drive a few suburbans or another xl but will most likely go back to a pre 15 model. Haven't even had it 2 months and I can't stand to drive it due to the buffeting... Headache and ears popping within 20min. Have been trying different things in hopes of finding a solution but no such luck. I still can't get over the fact a vehicle built today can cause such discomfort especially at this price point. I find it hard to believe, given how many I see on the road, that they all have the issue.

 

For those of you that own one with the buffeting /pressure problem , have you driven one without the issue?

For what it's worth, here is an update on ours. I don't drive it regularly, but I did drive it yesterday and today. To me, it seems there is virtually no buffeting on the highway (100-110 km/hr). At lower speeds, there is still the very noticeable boom sounds. Now, we've got about 20,000 km on it, so one must wonder if the buffeting is getting better over time. But, the vibration in the steering wheel and the boom sounds over sharp bumps in the road and at lower speeds still every bit as severe as it always was.

 

Anyway, thought I would share that.

Hi all,

 

I've put another 1,000km on the odometer since my last post with about half that had me driving more slowly pulling a trailer. 115km/h and 65km/h [71mph and 40mph] are definite sweet spots for me. I didn't have much weight on the trailer and didn't notice a difference w.r.t. the boom.

 

I do not notice a vibration in the steering wheel or the pedals as some folks in the Silverado/Sierra forum do. I may feel a little in the driver's seat. Maybe my ears are more sensitive than my seat-of-the-pants-o-meter...

 

My Yukon goes into the dealership on Thursday to investigate the vibration/boom. And to diagnose why the wireless charger randomly stops charging...

The 6 hour road trip this past weekend in the Denali was not an enjoyable ride especially above 65 mph.

 

Towed the boat (Ski Nautique) to storage today. No booming, buffeting or air pressure issues. Smooth ride and quiet! Maybe I should just leave it hooked up throughout the winter!

 

Going to buy then try roof rack cross bars to interrupt the air flow across the roof to see if that will help with the booming and buffeting.

Interesting.....I experience a ton of body booming at slower speeds on rough roads. I notice little or zero booming on the same roads under hard acceleration (i.e. when accelerating from a stop sign or traffic signal).

 

The hard acceleration makes the truck "squat" in the rear and loads the rear suspension. The weight of your boat and trailer do something similar. I do think the rear suspension is part of this issue.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
