2015 YUKON NOISE IN CABIN

GMC21 · June 7, 2016

We were in the market for a 2015 or 2016, but with these known issues and no clear fix, topped with rust issues on a well kept 2011 that the dealer and apparently GM didn't care to stand behind, we decided to try something else. We had paint issues on our 2005, 2007, and 2011. On the last one they fixed the two spots just above the rear tires, but they returned in the same places about 11 months later. They strung me along until I had enough and sold it. We are enjoying a trouble free Audi.

_{Considering the 2017's will be rolling onto dealer lots very very soon. Nothing is probably fixed, or redesigned....}

I have owned my 2015 Yukon since Sept there was some slight pressure in the beginning and the pressure went away after 1 mo, there trucks has no made buffeting or boom noises, its ultra smooth. Very happy with my purchase.

Regarding your Audi purchase; just be sure to get rid of it before the warranty expires....

Hey All, its been a while. Hope you guys are getting some answers with appropriate resolution... Whatever happened to the "Exhaust Fix"? Did anyone find any resolution? Any chance they will have figured this out for the 2017s?

I drove one today. Seemed ok but I did expect it to ride a bit better, not a issue just stiff. I did experience one vibration. At about 30 mph I gave it a little gas and for a couple seconds I did feel a vibration, then gone. My guess is it was in 4cyl. mode and a little gas and it couldn't handle it and jumped back to 8cyl. Does this sound right? Does 4cyl. mode begin at any certain speed or just whenever it fells it can. Does anyone else notice anything like this. I tried to do it again but could not.

Once I am at a set speed and on flat terrain, 4 cylinder kicks-in with no vibration or no notice. This could be at 35 or 75. To answer your question, on my truck it happens at any speed and whenever it feels it can.

If I had to describe this feeling it would be like driving a manual transmission and shifting to 4th when you were going for 2nd. I think the engine active fuel management and the transmission don't work together seamlessly. After more research, I found where it said the switch from 4 to 8 takes only 1/20th of a second. So how do you know if it is in 4 or 8 or does it really not matter. Can you feel it change back and forth? Can this feature be deactivated without a check engine light on?

My transmission does not drag like going from 1st to 4th. If I drive down the road with the windows up, radio off, and no talking in the truck, I could not tell when the truck goes from V4 to V8 and vice versa. The only way I could tell would be to look at the dash. Knowing my truck is in 4 or 8 doesn't matter to me 'cause the truck immediately transitions to 8 when there is a change of terrain or if I touch the gas pedal. I have not read if the AFM feature can be disabled.

If you switch the computer screen in the dashboard console to show your gas mileage it will have an indicator on the lower right to show V8 or V4.

On my 2016, it sometimes feels at slower speeds (35-40 mph) like a manual transmission lugging in too high a gear causing some slight vibration. But the 22 -23 mpg on the highway is well worth the trade off . . . to me at least.

That is likely it. I was going about 30-32mph and with slight gas pressure it vibrated for a second or two then instantly stopped as I speed up. Drove it again today, since it was bothering me, and could not recreate it. Ran it up to 80mph and still smooth. I must decide if the $3500 rebate is worth the risk.

How do you know if any roof bows have become detached? Can you tell be looking at the roof or feel it in any way. Or is it only that when people take it in for booming/buffeting that they find they have become detached. I guess my question is, are there thousands of Yukons [and others] driving around right now with all bows detached but it just happens to not be as noticeable to the owner. Even if my Yukon XL drove quiet as can be, I would always wonder if any or all bows are still glued down.

Still waiting for a response from GM as I asked a few days ago, before I even consider buying one. And their is only one left the way I want it so hurry up with that answer.

I dropped my 2015 Chevy Tahoe PPV at the dealership to have the brakes fixed, rattling noise from passenger side 2nd row seat, vibration at various speeds fixed and wind buffeting (however, they said because GM has not released a guaranteed fix that they would not attempt to fix it and would need to speak with an area representative).

Does this sound right?
