2015 YUKON NOISE IN CABIN

Ozzii · November 13, 2016

Did you have 20" rims or 22"s?

20" rims

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.
