Quick update to my initial post. (12 days into the issue) After constantly badgering the dealership for two days, I get a phone call. "After discussing the issue with GM engineers, we are unable to diagnose the issue. However, some tolerances in your rear end were slightly off, therefore we are planning to re-build your entire rear end. It will take us approximately 5 days to get the parts, then a few more for the labor." I responded to this by contacting the head of the service department, who was completely unaware of my ongoing issue. I instructed him to re assemble my truck, and I will pick it up, and bring it to the dealership where I initially purchased the vehicle. I am heading in to said dealer tomorrow, and I am not planning on leaving until I am provided a new truck. After further discussing my problems with the GM customer service rep handling my case, she has labeled the issues as "unresolvable". Hopefully this will assist my case in convincing my dealer to replace the vehicle. I will post updates when I return tomorrow.

So I have decided to post my ongoing vibration issues to the forum, as it appears I am not alone in this journey. About three weeks ago, I purchased a 2014 Crew Cab, 2WD V6 Silverado with a 6.5ft bed. Recently (as in last week) I noticed a vibration resonating throughout the truck when I reached 30mph, and when maintaining speed, the vibration remained as well. I decided to bring the truck in to Chevrolet, and after a test drive with a service tech, he acknowledged the issue. After leaving the vehicle at the dealership, the issue was diagnosed as a bad drive shaft from the factory, and therefore covered under warranty. I was provided a complimentary loaner vehicle while we waited the four days for the drive shaft to arrive from Michigan (I am in Florida). Yesterday, I received a phone call from the dealership informing me the new drive shaft had been installed, however the issue was not resolved, and in the words of the tech, "it might be a little worse." He then informed me, they were now unsure of the source of the problem, and they were "attempting to figure it out." No progress update today, and no prediction of a timeline for resolution. I have researched the Lemon Law procedures for FL, and I now must wait 7 days before formally notifying the manufacturer of the issue (the vehicle must be "out of service" for 15 days, OR Chevrolet must have made 3 separate attempts to fix the issue). It goes without saying, I am extremely frustrated that this is happening with a brand new vehicle. And additionally the lack of a priority I feel the dealer has placed on resolving it, has not done much to ease my frustration. Hopefully good news comes soon! I will keep you all posted on the progress.
