Indeed. At 9K miles, friction plate should have plenty of life left. Sounds like your clutch wear is secondary to whatever happened originally. Good luck!

Happened to me today. Driving to the gym and clutch started to feel a bit weird, but thought my seat was just misadjusted and didn't think about it. Coming home, clutch fell right down and then the engagement was on the floor, and then nowhere at all, and wouldn't return. Stopped at a red light and couldn't get moving again :(
Clutch fluid level looked fine, might have even been above max, but looked very dirty.

Once I figured out how to drive without a clutch, limped to the nearest dealership and it's sitting there now waiting to be looked at.

Clutchless shifting and using the starter to get moving (while clutch pedal is to the floor)?

Yup... and not stopping at stop signs

Good news, They're replacing the master, slave, and hoses all under warranty.

Got an Altima 2.5S for my troubles.

Update: Got the car back on Thursday, Everything seems to be working fine.

Here's the results if anyone's interested:

Happened to me tonight. I noticed that the clutch had been feeling funny but thought it was just because it has been so damn hot here. Well driving normally, slowing for a stop sign, push clutch and lost all pressure. The pedal was stuck to the floor. Behind me was a trail of clutch fluid and fluid is leaking from inside the bell housing. Ill be calling Nissan in the morning and getting it sorted out. I am still under factory bumper to bumper warranty until Sept.

dragonbreath - Be glad you're still under warranty. I'm 3 months past the warranty with 21,000 miles and the CSC went out this weekend. Dealer wants almost $1000 in parts and labor to fix it.

^^I'd take it to a local shop and install one of the heavy duty CSC's available. Probably a good idea to replace the master too...?

Yes and Yes!

Yeah my local dealer took care of me. Fixing my car, paid for the rental and the tow to Nissan.

The service writer told me that the CSC failure is covered under power train so you should still be under warranty correct?

Ended up negotiating them down to $550 for the part and labor. My warranty is expired, but since it is only 3 months past and only 21000 miles, they cut a deal.

Now that it is replaced, the clutch feels better than it ever did even when the car was new. Clutch pressure always felt like a bit too much before and engage points were weird, now it's a bit lighter and shifts from 1st to 2nd are now spot on - no more jerky, shifts... always smooth now unless the operator (me) screws up. It's actually even more fun to drive now.

it happened two days ago cruising at about 40mph. glad i could get help and info from thia forum. seriously.

yes i drive the car hard and track it but this car is met to be driven like this imo. i can understand this problem more than the oil temps being too high.

anyone tried any aftermarket csc?

I took it to the Dublin, Ca Nissan Dealership this morning and I just got the call back from them telling me they couldn't figure out what the problem was and that they had to have a Nissan Rep come out to take a look. I don't understand why a Nissan Dealership needs a Nissan Rep to come out and take a look at my clutch but I'm hoping this gets resolved tomorrow. I'll update as I learn more.

UPDATE 8/9/12: Just got the call from Nissan. My master and slave clutch cylinders both failed, they wont have the parts until Monday or Tuesday so I get to keep the Sentra till then. All will be covered under warranty so that's some good news.

Ordered the ZSP Heavy duty cylinder. lets see how it works.

It's great as long as you have the master cylinder adjusted and bled properly. You don't want more than 1" of play before feeling the resistance. Talk to Joe@ZSpeed as he provided valuable advice for the bleed procedure. He recommends cracking open the hard line to the master cylinder to release trapped air before bleeding the CSC.

My engagement point and pedal pressure has been consistent for the past few months regardless of temperature. Before it was all over the place.

Are you guys taking in your Z with aftermarket parts on the car? After driving on the interstate for 30min my clutch is really soft and engages about 1" off the floor and I need to take it in. I have 37,500 miles on the car.

I'm all turbo'd and still take it in. They love my car lol.

So add another one to the list...
2011 Nismo

I just encountered this issue yesterday. Clutch traveled halfway before engaging. Later on the highway, the problem got worse and the clutch had to be pressed to the floor to change gears. Occasionally, it would also get stuck and I had to pry it back with my foot. The problem seems to be intermittent for now but I took it straight to the dealer. They drove it and said they couldn't find anything wrong. They kept the car for a day and gave me a Versa for a loaner (ugh).
Dealer called today and mentioned that the car is fine and that it is most likely a heat soak issue. Thanks for the posts and comments in this thread cause I'm headed there tomorrow with proof in hand and a demand to inspect the car more thoroughly.

Mine is in the shop ATM still being inspected. I have 123 miles left on my warranty and awaiting if everything is gonna get covered. This happened while I was going to canibeatxhellaflush this weekend and couldnt show. :shakes head: PITA as its my only car. If I went to the show I wouldve been real close to being over the 36000mi warranty. Was at the toll road and forgot i was in gear and let go of the clutch. Gave it gas to save it from stalling and was able to keep going but noticed a squishy pedal and eventually the next morning could not put it in gear. Well see what they say. No fluid in the res.

Same symptom happened to me three days ago, although mine only takes the car to warm up in the garage before coming back to normal clutch pedal feel. 40k miles no leakage. Will be taking it in. Oh yeh ....I purchase the 100k extended warranty both of them. Doubt its the clutch worn.

Finally got my car back. Seems at times the symptoms are still present. Im hoping theyre just air bubbles working their way out of the lines. Time will tell. The dealer is aware.

we need more info about this. i though we could just upgrade the CSC and no more worries. hmmmm

More info about what? You can upgrade the CSC and have no more worries.

i thought i read the master cylinder wasnt up to the task once you installed the upgraded CSC. i read it wrong, all you need to do is bleed it properly.

I havent done anything under the hood - just have ARK exhaust. started by being REALLY slow to come up after shifting for a few minutes (shifting to 6th). Getting off the freeway, had to pull it up with my foot to get it in 1st and 2nd to park at a gas station.. was towed to the dealer. We will see what they say tomorrow. (before today, no issues)

It would be interesting to note what sort of maintenance was done on vehicles with failed CSC's. Specifically, how often the clutch fluid was flushed.

I don't think most of us hit the mileage to require fluid flush before the CSC failed. Some owners already had a failed CSC and/or master after a few thousand miles of ownership.

IIRC, it's a failed O-ring inside the CSC that seals the piston, so it starts leaking fluid from there.

Digi, perhaps that's the problem...

The fsm recommends inspecting every 12 months or 15K miles. Perhaps that should read to mean replace it rather than just inspect.

The question is what causes the oring failure.

Found this either on here or the g37 site. Sounds plausible.

Clutch Care

16,500 miles on my ZSpeed CSC, no problems or failures. Used with OSGiken twin disk in a daily driver twin turbo car.

The bleeding isnt fun... but ill gladly take the nightmare of getting my clutch system bled when switching CSCs, versus having to tow my lowered car with a front lip back to the shop after breaking down in traffic!

yup. My case exactly and same with many others here.

1st time - pedal stuck to floor - Failed slave cylinder - replaced by dealer.
2nd time - no pressure/sometimes pedal stuck on floor - replaced master cylinder
3rd time - same as 2nd time - they said pedal assembly - replaced pedal assembly
4th time - same as 2nd time - they just replaced the whole clutch assembly (flywheel, pressure plate)

My car is finally back to normal (fingers crossed) but I will always drive scared...

Glad I used the search function before making a post!

I brought my car in for service last week (fluid changes and brake service)

Got car back and it felt pretty good, but then now I am getting the clutch pedal sticking to the floor, it happened a few times on short drives, so for sure getting worse. I wonder if thats related to them recently changing that fluid?

I'll be calling the dealership tomorrow

37,000 km = 22,000 miles

:tup:

Me Too
 

Happend to me yesterday as well. Pedal stuck to the floor, limped it home, check under the hood, reservoir empty, fill it up for drive to dealer, CSC gone bad. 22,800 miles on my 2009. So sad.

I was going to say it might not be a bad idea for us 6mt folks to carry a bottle of brake fluid in the trunk. Only problem, once its bled dry, getting the system pressurized again is not a roadside repair. If you catch it early enough, sure. Then again, the volume of the whole system is so small, how many pumps of the pedal will it take before needing a refill.

Probably a stupid question but do you guys drive with Syncro Rev on? I wonder if that Syncro Rev system causes clutch failure. I've been driving with it off ever since I had the clutch replaced.

Yes, I do.

It's not the syncrorev. The g's don't have that and from the posts on the G site, suffer a similar amount of csc failures.

curious to know what the production date on your 2011 is, just passed 26,000 miles on my 2011 and no problems with the clutch at all (knock on wood). mine was in the june 2011 production run just to get that out there.
