Thank you, Fishingbear. I will definitely keep that in mind when I'm at the dealership for the 4th time! I would like to try replacing the tires before anything else first. I just need to get them to put 4 new tires on now! Don't know if this is true or not, but the mechanic did tell me GM is not putting Goodyear tires on the newer trucks anymore and recommended Michelins.

I have a 2014 Chevrolet Silverado 1500 4x4 crew cab standard size bed with 20" Goodyear tires. I was starting to think I was the only one with this problem. I have been having the same experience with vibration at varied speeds around 75 to 85 mph. I took it back to the dealership about the 2nd week of ownership and they said there was a flat spot on one of the tires, so they replaced it with a new tire. Everything was fine until I took it in for the 1st oil change and tire rotation a few months later. I noticed right a way that it had a vibration again but even worse no matter what road I was on. I took it back a couple days later and they experimented by exchanging new tires from a new vehicle on their lot and said the ride was better. However, they said Chevrolet would not pay for 4 new tires for my truck so they removed them and put my original tires back on. When I picked it up, they told me it was solved by putting different amounts of air (nitrogen) in the tires(less in the back tires). I'm sorry, but that is not acceptable. Besides all that, sometime at the dealership, the plastic piece on the lower front of my truck got dented in!! They brought that to my attention when I picked the truck up! It wasn't there before!! I just figured claim it on my insurance! I have another appointment at a different dealership in town this Friday. I really hope to get this problem solved. I will post my results.
