Update from my last post...so my dealer (Mossy Nissan Escondido) confirmed a third CSC failure in 20K miles. I do have to say hats off to my dealer though. I explained what was going on and that something else in the assembly had to be prematurely failing the CSC aside from it's inherently poor design. They took my concerns to heart and they (yes THEY...without any prompting from me) started talks with Nissan HQ to make sure it got fixed right this time. On their first tear down of the tranny they replaced the CSC and their master tech checked out everything...the clutch/flywheel/master/pressure plate to see if everything was within spec. Nothing was out of spec (aside from the leaking CSC) so they put it all back together. Once it was back together they checked it again and didn't like the amount of play/chatter so they tore it all apart one more time and replaced everything. I even got some GTR fluid, ha!

When I picked the car up on Tuesday night, I immediately noticed a huge difference. My clutch used to chattered off and on from the day I bought it new and others on here had complained about the noisy nature of our clutch, so I just assumed that's how it was. It drove fine before, even though it chattered, so it didn't bother me too bad. But now...the engagement is much better and I can shift it like butter every time now. Best of all, there is no chatter to be found at all! I cannot say enough good things about my dealer. They have always been great to go to (I used to drive 30 miles to service my car at this particular dealer) but their extra effort to fix this issue has spoken volumes of their customer service. Time will tell if this CSC will hold, but so far I am very pleased.

From a stop, put into second and rev to 7500 rpm and then drop the clutch.:tiphat:

Good dealers like that are extremely rare in my experience. glad everything has worked out for you. AFAIK, clutch chatter will come back after a while

yea, because 7k rpm is not high enough:rofl2:

Update, Nissan HQ &my dealer informed me they are going to replace the whole clutch and put in a new one. I'm hoping this does the trick.

Dude order the HD CSC and take it to them and say "hey use this instead" and let them install it. Done and done. If mine had failed 4 times eventually id be like screw this.

Link to order HD CSC?

Hey guys, This happend to me too. clutch pedal was down, clutch was very short, somtimes with no respond at all (stuck twice on the side of the road haha)..
well at first i was thinking to replace the CSC but first i told my mechanic to try replacing the clutch fluids cause there might be air bubbles inside. the clutch pedal came back to place and act normal. anyways im going to buy a new CSC to lay in my house just in case...

Thanks alot, this theard was very usefull!

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.

More of an indication of air in the lines. Air might have entered through the csc by the seal but if the seal failed completely then the fluid would have drained and you never would regain pressure

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.

I would do that but my car is a lease and there is no reason y I should spend any of my money to make a relatively new car "work" properly

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.

Hmm I'll have them check in a month or so next time I'm in for service

when my slave went out i was able to put fluid back in the resivor and drive it for a day but the pedal was jacked up. the next day i could do nothing.

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.

im confused. once you open the tranny you have to replace the OEM CSC no matter what. its not supposed to be reused. the fact it went out 1000 later makes sense.

Wow cant wait, these new Clutch Master Cylinders will sell fast!

Update to my #300 post
 

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.

VIN: BM554556
Purchase Date: Oct 2013
1st failure- Nov 30, 2013- final "STF" (Stick To Floor) 11/30/2013 @ 1:27PM CST
Occurrence Mileage: 37K Miles
Clutch Type: OEM
2nd Occurance: Just 45 days after Replacement of Slave Cylinder and fluid - Bell housing leaking also. 1/19/2014 HWY 635 - Dallas Near Addison and NDTollway

Update: ON the way back from old apartment in a last final trip, clutch dropped to the floor only 45 days after being fully replaced by Trophy Nissan in Dallas. To say I am pissed and livid is an understatement at the moment. To make matters worse, they still owe us parts from WE OWE when we bought the car. TOP off matters , on the last time we were in we found out the car was in for this same issue just a month earlier in which they said it had been fixed then also. SO that would make for time 1 prior to us buying the car (upon trade in as the Service manager told us), 11/30 the time we brought it in, making time number 2, and now time number 3 which is 1/19/2014. This is a Effing nightmare. Have MPP 6/100,000 coverage when we bought it, and it's still under the 5/60,000 Powertrain as of right now. SMH....WHAT THE F***.

Does anyone know if i can tell the dealership to order ZSpeed Performance parts and replace em with that? I don't think so, but i figured I would ask.

Thanks for lending shoulders my Z family.

I would make sure they replace the clutch assy and flywheel this time. It must be what is causing this many failures of the stock slave, I mean yes the slave is junk, but normally last OK with the stock clutch unless something is wrong with the stock clutch assy.

So I have basically read through this entire thread. I have a clutch issue but am able to pump it back up and there is no fluid loss. I have the ZSpeed CSC on the shelf. It looks like I will need to replace the Master Cylinder as well. I am really debating on replacing the entire clutch and flywheel and just be done with the whole thing. I have 46K on my '09 right now.

Another question: Is there a DIY for the CSC, other than what was written up on page 20 or so?

Sticky: 370Z Clutch Pressure (CSC) Failures
 

No fluid loss=bad master, fluid loss =bad slave

DIY section here has a pretty good guide w lots of pics but not a sticky is towards top of first page.

Thanks for this, and after finally talking to our Service Manager and the director, I have told them to look at those in replacement, as well as having them contact your line of business for proper HD parts to rebuild instead of OEM garbage which was originally installed on the car. Crossing fingers right now. They have had the car for a week now, and are saying it will be no quicker than next thur or fri before we get it back.

ive never heard of a dealer putting on none OEM parts for the tranny or hydrolic system. be cool if they do though!

Highly doubt they would because if that part fails they are not liable for it.

Here's the kicker of that whole definition as was told to me in the last meeting we had. Since Nissan is aware of this issue, the CSC falls now under the base 3/36 warranty and so those which are outside this, Mine (38K) miles , and being rebuilt 2x already now, it falls to my Aftermarket MPP Warranty which i purchased with the car when i bought it. Thus now, allows them to buy and replace with any parts suitable and warrantable by the MPP company we have approval for. Correct in your statements if its' under their Nissan OEM 3/36 warranty then yes, OEM would be the only way they would go. However as I have been informed that its now not part of the 5/60K warranty powertrain (not sure how much I believe in that) but i got the phone call from MPP saying they would approve the repairs and rebuild. So we will see i guess. If they don't fix it correct this time and it goes out again, I'm going to another dealership.

So is there s TSB or Recall on this?? =/

There is a TSB as I had mine replaced with 1,200 miles on the car and the service manager told me as much. They couldn't replicate the issue but replaced it since there was a TSB. Not sure what the number is though but you can probably google it and find a list for everything for your year model.

Can someone else please verify/confirm this as well? What does it cover? Just transmission oil?

Fyi

What's interesting in more information that I received lately from another Nissan source was that in the Powertrain warranty it's for Transmission - All fluid and mechanical working parts within the transmission. Which means since the clutch is on the outside of the transmission, it according to this source, falls in the 3/36 and not the 5/60 warranty. Got to love BS small writing. Either way it's covered under the TSB that is listed above :

Doesn't cover newer! My 2012 csc was replaced last year and 2nd one is going out soon

interestingly enough, it was posted on FB that Z1 is coming out with their own CSC:

NICE! but not a Csc as a csc is a concentric slave cylinder. This would just be a slave cylinder. a better option in my opinion. This slave will utilize the traditional cylinder fork and throwout bearing. Not quite as neat as the concentric slave option but certainly not less reliable.

mine was replaced under warranty at 24k miles. im at 62k now and the fluid looks horrible and i hear a little "hoot" sound when i press the clutch in. i took as much fluid out of the resivor and filled with new fluid but im sure she is doomed soon again.....

wait, is this during shifts? sometimes during a shift ill hear a "hoot" sound after an upshift. was thinking it might be air. if its the damn CSC i will strangle someone. damn car!!!

my "hoot" sound (like a baby owl) is during the first few inches of travel on the clutch pedal.


i also hear a nasty sound during extremely cold starts in the morning. i have no idea what that sound is.... :/

chops our cars are so close to the same build date! im 517 your are 528 of the same year.
