Since I have had the 07, it the clutch has only stuck maybe 2 times in normal city driving conditions. It hadnt happened over 2 months. Decided that I should finally take the 07 to the track last night. Bad Idea. I launched at 3,000 rpm and the f-ing clutch stayed stuck to the floor. I decided to call it quits after that. I will be heading into Nissan come monday. I highly recommend going in to Nissan to fix this before heading out to the track.

 

I had the same exact problem with my 06. Went to the track and my clutch stuck to the floor TWICE. Take the car into Nissan and have them make sure you don't have a defective master slave cylinder. If everything looks good change the brake fluid to high temp brake fluid like MOTUL and also buy yourself a SS brake line. Once I did that my clutch has never stuck again. Problem fixed.
