Anyone having an intermittent problem with clutch resistance? Sometimes mine is incredibly light and buttery smooth, and sometimes it's much more stiff and resistant (and almost "scrapes"; it's very difficult to describe). I told them about this when I brought it in last time and of course, "it feels like every other one on the lot". It is a totally random and intermittent problem - and it may not be incredibly obvious at points . However I drive this car at least 2 hours daily (9000 miles), and I know when it's right and when it's wrong. Anyone else?
