Vibration

Mine feels, perhaps, a touch less smooth in V4. Certainly not enough that it worries me and it's far less than my 2010 1/2 ton Suburban did when in V4.

The sensation is as if the engine is running roughly, not really a vibration.

Right.

Yes. That might be correct. It's almost like I have a 12 inch subwoofer in the back with some really deep base. Lol.

It doesnt drive you guys crazy? Maybe I'm just too sensitive to it.

I notice it all the time, and it can be annoying. But I have also asked passengers if they can feel it, and they don't. I noticed today that the change in the sound of the exhaust is also very different running four versus eight cylinders. Honestly, if I could "turn it off" as a feature without worry of screwing up my warranty, I would.

I should've been more clear. Without spending $200 to do it.

I am thinking about buying it. I wonder how much gas mileage I would loose with it??

Any other negatives I'm not thinking of?

Same issue here. It is driving me crazy!!!

Not only do I get the vibration, I get a fluttering sound.

There is a thread over at gm-trucks.com (link below). I check often to see if anyone is able to find a fix.

I just picked up a TAHOE 2015i ltz with 200 miles on it.

I get this vibration sensation at idle. It drops to 500 rpm and feels almost like it will stall. This can't be normal.. I rented a 2015 Yukon for four days and don't recall it doing this.. Found this: http://sandyblogs.com/techlink/?p=3780
