I too have the issue on my 2015 LTZ Crewcab. Had it for a couple of weeks. First time it went in they rotated and balanced the tires. Picked it and noticed not much changed. Took it back last week they road force balanced the wheels and tires and replaced three of the tires as a result. Condition is improved but not gone by any means. Started to think it was just me as I've only had cars for quite awhile. Took it back this week after chatting with my sales guy and and he took it for a drive and confirmed it wasn't just me. He spoke to the Service Manager on my behalf and it will go back in on Tuesday when he said they will get the GM engineers involved. I'm cautiously optimistic since they seem to be truly concerned with getting the issue resolved.
