My biggest improvement came from 20" wheels on KO2s religiously RFB down to 15lbs or less ... but, I did install the Borla touring and noticed slighter improvement still

Most test drives are the courtesy 2 mile dealer loop - you're excited about a new truck so it doesn't stand out

Esc is no different than the suburban and denali - go test drive a lot of them, you'll find a few good ones.

Good ones are out there, you just have to be willing to be diligent and test drive a lot of them

Search the thread, it's in here - not sure if those posters are still active but 100% problem returned

IIRC both members that had the roof fix saw the problem return after the bows came undone again, I also thought GM was no longer doing the roof work

You should have the mod make this a sticky; what's happening is every few months as users churn, and new people arrive here, this info gets lost

I'd flip it, some vibrations are from the tires, others elsewhere in the powertrain I'd have an independent tire shop road force balance the LTX and see if the issue is still there

IIRC someone here had the exhaust fix and problem still returned or am I mistaken? If so, likely denying it for the same reason the prior roof bows repair was pulled - doesn't last

You answered the question in your question ... it's automatic

I have KO2s, improved my buffeting but I was also strict about getting RF values below 15 but you need to run 20s If you have 22s, get the Michelin LTXs ... people are swearing by these as making a huge improvement to booming and buffeting, reviews over at tire rack are the best I've ever seen for any tire

Website reads "leather appointed" so you can't even be sure it is all seating surfaces like before (where they would write seating surfaces)

It's still speculation re: improved body mounts, but here's picture and link if anyone wants to compare to a 16 .. best way is to go test drive some 17s http://www.tahoeyukonforum.com/threads/2017-yukon-xl-denali.85107/page-4

You do know that GM once had an official memo for the roof repair but have since pulled it - no official reason but suspect due to the bows coming undone again - so it's definitely the roof, and I do not think we'll see a future fix from GM Reduce inputs into the vehicle and/or the "rip" roof fix are the only ways to go

Fair points except that the last gen didn't suffer from this issue hence the complaints ... like your cargo van example, that sensation is always in a cargo van and pretty much expected in future/new vans
