This may be a stupid question, but I'm assuming there are some Tahoes/Yukons on the road that don't have this issue (in other words there are lemons out there but not all are lemons)? Or...is this a problem with every Tahoe/Yukon, prior to a certain production date, and the issue/phenomenon is just more noticeable to some folks and/or more severe in certain trucks?
I don't recall feeling any weird sensations or hearing any unusual sound when we test drove one. However, I was planning on buying certified preowned and this thread has almost certainly destroyed that idea...
