So I was pulling out of dunkin donuts today and noticed my clutch pedal lost a ton of it's resistance. The car shifted fine but the clutch pedal had almost no resistance down to the friction point. Actually it seemed the friction point was closer to the floor. Than after a little while of driving it felt fine and was back to normal. Could this be an indication of the csc failing? I'll also add I have a 2012 purchased in march of 2012, ~36k miles. No tracking or anything like that.

mine acted odd like that a day or two before it went.

Right before I pulled away I actually did kinda slam/push the clutch in really hard and fast because I had to stop quickly. Could that have caused it also? It feels perfectly fine today, haven't had problems since.

You have a master cylinder dying, If the slave goes it doesn't "kinda" go it just blows out. The Master is leaking internally and bypassing the seals and is why the pedal is acting weird.

We are currently testing our new Clutch Master Cylinder for the 370Z and G37 to prevent this problem in the future.

Mine went south 2 weeks ago ( 12243 mikes). Car was stock up to 9445 miles, supercharged right after and upgrade the stock clutch to Exedy stage 2 and fly wheel at 11200 miles, then in just 1000 miles the stock CSC fails..
I ordered the Z Speed Performance unit and it seems to be a very nice strong upgrade. Time will tell.

VIN: 553000
Purchase Date: June 2011
1st failure- Aug 2013- final "STF" (Stick To Floor) 10/16/13
Occurrence Mileage: 32,000
Clutch Type: OEM

Update: Last week (Jan 2014) at 34,350mi. pedal started to get mushy and not returning. Limped it to Baker Nissan (awesome service) where I explained what it was doing and that TSB was done in Aug. They simply said they will take a look and fix the problem and gave me a free rental car. They called me the same day to report the CSC is leaking and it will be replaced. Once they replaced CSC and test drove car the Master was not pressuring the system so it was replaced as well. Glad I did not have to get towed and it was a painless experience with dealer to replace under warranty which expires in 1,500mi and I opted out of extended warranty. I will replace next failure with Zspeed and tell everyone Nissan clutch systems are weak until Nissan addresses. Thank You Baker Nissan for not making me have a horror story like others on here.
