ANYONE ELSE HEARING LIKE A BUFFERING SOUND? MAKES YOUR EARS FEEL LIKE THE WINDOW IS DOWN, BUT IT IS NOT? I TOOK IT BACK TO THE DEALER, THEY HEARD IT. WE GOT IN ANOTHER 2015 YUKON XL AND HEARD THE

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

I think my yukon was one of the 1st with the new exhaust, fixed the buffeting issue for less than a month then it slowly crept back.

Do you still have the booming at slow speed over bumps? I have no buffeting after the new tires but at speeds from 1 to30 mph I notice the booming over rough roads.

Im also curious to see if anyone tries to switch out the body mounts with the 2017 body mounts.

So far, haven't seen part numbers for 2017 Tahoe/Yukon/Suburban on any of the on-line parts websites I've found. So can't compare part numbers to verify that the 2017 has new body mounts. Also likely means may not be able to order yet.

So after my 82 day old Yukon has been in the shop for 62 days on its 4th repair attempt, GM customer service has refused to buy it back and exchange it for a 2017.

 

Thier reason.....get this...GM has bought back too many cars this year.

 

They have agreed to replace the tires with Michelin Premiers. I have also told them that they need to replace the 22s to the Denali 20 rims. And they need to add the dampers to 6.2 exhaust.

 

Side one the exhaust dampers, after denying that they existed to 2 service managers, my most current service manager forwarded them the VIN of another vehicle that had the dampers installed. They then admitted that the dampers exists, but said I don't qualify for them. Can't even begin to understand why.

 

So dampers for the booming, and 20s with Michelins RFB under 10 lbs should resolve these issues.

 

If not, it's lemon law time. Already reached out to an attorney.

 

Plus side, I have co-workers who were buying GMs at the end of the year. A Yukon, Acadia, and another getting A Silverado. They have all moved on to other brands.

 

We've made two payments on the truck and haven't even driven it.

Yes, I still have the booming while traveling at lower speeds over roads that are not smooth.

Been following this thread since the beginning, waiting for a hope of this problem being resolved. I need a new Suburban pretty soon!

I just read an article about buffeting in the latest Car and Driver that made me think about this thread so I thought i'd just mention it. Their conclusion was that buffeting is caused by outside rear view mirror design. They gave no specific vehicles, just aero testing. Maybe it's related since the mirrors on these vehicles were made smaller in the latest version. Just adding more fuel to the fire.

Outside mirrors??? This makes me laugh. I think they are really pulling at strings at this point.

I took my Yukon BACK to the dealership and road with a GM Field rep again yesterday. They told me to come back today to get my car and that I needed to speak with the service manager. Doesn't sound like good news to me. I will keep everyone up to date on what they say to me.

definitely not the mirrors. I've folded them in while driving with no change and I believe in another thread someone removed them to test. It's much bigger than just mirrors. lol

I dropped the headliner (I own a car garage) and hit the metal roof from the inside with the side of my hand and was able to reproduce the sensation. I'll post a video if you want, but I feel the roof moving is the root of the issue. I'm going to put a GoPro outside and film the roof as I drive and see if I can see it moving.

They made them smaller than they used to be. Maybe folding them in or removing them is the wrong direction to make any difference.

 

 

The go pro thing was done by someone already and it moved as was posted way early in this thread.

I have stock mirrors and my truck does not buffet, not the mirrors. Can't see how outside mirrors can affect inside the cabin with windows rolled-up? Car and Driver may need to stick with the title of their magazine if their comment was in reference to the buffeting with the fullsize SUVs.

I guess you need to read the article then?

Don't need to, 'cause if the article is about fullsize GM SUVs buffeting from the side view mirror design, it's a lie. Or else my truck would be buffeting also.

I mentioned this a while back but too big a problem to tackle for most people. Since you can do it, and you have the headliner down, buy a gallon of bed liner, and paint the entire roof. It will be stiff as a rock. That was my plan, to do the roof, pull door panels and get what I could reach and pull back inner liners and do the inside of the quarter panels. Most people think the very thin sheet metal on the entire truck is vibrating like being inside a drum. Stiffening all the panels may help. I decided not to go thru all this and ordered a pick up truck but still follow this thread in case it gets resolved before the pick up arrives.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Getting greedy...   The AC pump has been replaced at least once per service records, and it's been recharged twice since 2018 or so, in approximately 2 year intervals between those charges.   It was done at the same shop...clearly they were enjoying the revenue of recharging the system periodically versus actually tracking down and fixing the leak. I learned that the owner was 88 years old when she passed in 2023, so maybe they assumed only a temporary fix was needed anyway.   The system is basically empty now, the compressor spins freely, so I'm guessing it "just needs a recharge".   I vacuumed it down, and it has basically held overnight. Doesn't appear to leak under vacuum, check! So it must leak under pressure. I don't have a way to pressurize the system and pressurizing it with shop air wouldn't be great for the air dryer (which is probably toast anyway?)   The dryer (accumulator? I'm not an AC expert) has a Schrader valve, but the high side has an old ball-type valve, which are notorious for leaking. It's clearly had schmutz blown out of it at one point because the line/area next to the valve is coated old black crud, which I assume is AC refrigerant residue/oil, or maybe even dirty dye. I think I'll roll the dice and replace the valves. I have a black light around here somewhere so I'll find it and shine it around the engine bay in the dark to see if there's any dye.   I can't think of another way to track down the leak other than injecting some dye (if it doesn't have any) and having it charged up. We can't buy R134a off the shelf here anymore, so I'll run it up to Jiffy Lube and have them do it. I think I have a coupon. At the very least, the charge should last long enough for a year or two, according to history. I think this truck will be long gone by then. But cold AC is a selling point.

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By clowe1243 · Posted

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!

      If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍

      primary drive belt tensioner

      By Bill Lemmond · Posted

      2022 2500HD Crew Z71 Duramax single alternator.  Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Atlas · Posted

      +1 for the 3.0   Perfect for 1500 pickup towing duties.   Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town.   It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether.   Drive one, I think you'll like it, though...
