Love the truck. Hate the drivers seat. So much so that I don't even like to drive the truck. I noticed the problem within 2 weeks of purchasing the truck. It is not only the seat movement issue, it also feels like the seat bottom upholstery has shifted around to the point that it feels lopsided. I have not contacted the dealer as yet as I am hoping that GM will come up with a fix that actually works. I read this entire thread and do not see an definitive fix that can be completed by the dealer. I want them to fix it and fix it right. No hose clamps!
