I agree. I would love to have a contact list so I can throw my hat in the ring. I haven't been through all the hoops most have had, but would like to put my best foot forward also.

Giving I've only taken my truck in once to get serviced for said issue, would I benefit from opening a case with the BB over the vibration issue since they have told me no solution is available right now and I will be contacted once a solution is determined?

Well I am now joining in on this excitement.... I recently purchased my 2014 GMC Sierra Z71 4x4 Crew Cab 1500 with the short box. I noticed a vibration that is noticed around 65+MPH, but felt most at 75-85MPH. I took it in for service for the recent recall ( 4x4 slipping from neutral or something of that sort ) and to have them see about the vibration. They called me ( Hiley GMC in Fort Worth, TX ) today to say the service was completed. I called back to see what the vibration was and to see what their fix ( after reading much of this post ) was. I finally was in contact with the service guy and they told me that GM was aware of the issue on all 4x4 truck and a fix is not yet available. I asked when he thought a fix would be rolled out and I was told most likely in the next 2-3 months... Geez.... My truck just rolled 1000 miles this weekend also.
