Just wondering if any other cold weather Prius owners have ever encountered a squeaky drivers seat on particularly chilly mornings. I'm a larger guy, so that probably contributes to the issue, but if it's in the neighbourhood of -5 c the seat squeaks like crazy. Any pressure on the backrest, andy bump in the road, and shift in weight and the car sounds like I have a handful of mice living in it (it's a new car, and there's a strict no food policy so I've ruled the mouse thing out) I actually have a service appointment tomorrow to have entire drivers seat frame replaced (under warranty) for this issue, but I was wondering if it was a documented problem? I did my best to google before asking, but my search seemed to turn up relatively dry...
