Pretty sure I just had my CSC go, car is less than a year old. The pedal is on the floor and there is a nice puddle of clutch fluid under the car dripping out of the bell housing, needless to say the clutch reservoir is empty as well...on the phone with Nissan road side right now...
I had about two gear shifts from when the pedal would come up to 50% and I brought it back up with my foot, until it was on the floor and I could no longer disengage the clutch and it stalled.
