Sticky: (Official) 370Z Clutch Pressure (CSC) Failures

kail

Just went in for a csc issue to the dealership. 48k miles, only powertrain warranty.
pressure plate, clutch, csc, cmc are getting swapped, words from the svc manager 'we'll get it under warranty, its all in how you code it when you write it up'.
not sure how, dont really care, hes getting tipped.
thats the good news.. still has the temp tag on it is the downside..

Mine is an '09 w/ 45k miles with only a maintenance warranty (which pretty much only covers oil changes and checkups). I wrote my story a few posts earlier, but pretty much clutch just stuck to the floor and had to have it towed as i couldnt get it into gear even by pulling it up manually.

Instead of paying the dealer $1800 to replace the clutch, I towed it to a mechanic who also advised my clutch needs to be changed along with the CSC (charging $1100). After reading this thread, I told him to just change the CSC which he did, but now my "sweet spot" is much higher than it used to be. He said the oil (i'm assuming the transmission fluid that leaked) also leaked onto the clutch so the gears are slipping? I am a little mechanically challenged so if someone can shed some light on this issue I'd really appreciate it.

Side note: I am a grad student who commutes 30 miles each way to Downtown L.A. 5 days a week (in gruesome stop and go traffic). I love my Z and really don't want to get rid of it but I cant afford these types of repairs every now and then, so im considering trading it in and getting a reliable automatic honda or something until I finish school next year (since the mechanic told me that stop and go traffic is wearing out my clutch)

Any advice? Perhaps some extended warranties anyone knows to suggest?

Went in last week for mine (2012 with 14500 miles ~18mo old, mainly driven in the city) because my engagement point went to the floor. They did the TSB for replacing the clutch fluid, which lasted about a week, and then happened again. Just got my car back today and they replaced the master and slave.

I never knew about the "judders" issue, but I definitely saw that happening the past few months and thought something was up with my intakes/MAF.

Mine went out at 33k miles. I was able to get the car on aside road before the system was completely empty. The MC was dry when I checked it. I have the extended warranty thankfully so its covered. Curious to know what the difference in the GTR fluid is since that is what Nissan is replacing. I should know today if the MC and clutch are also being replaced with the CSC

We fell victim today at 36,129 miles pushed it to the floor and never came back, pumped it a few times and then it came about 1/8 way back. Enough for us to get her out of the parking garage to the street. Towed all the way back to the dealer, have not even owned it for a full month or made the first payment. BLECH! ... Got a loaner now we wait.

I was victim today of the clutch down to the floor, in the middle of a Friday evening traffic, going back home.... I had to call road assistance, and was able to left the car at the dealership for service, so they can work with the car tomorrow... I hope to don't have the same issue again... If it happens again, then I will replace it with a aluminum/steel construction CSC...

My Z is only 4 months old and have 2500 miles.

Sad to see a 2013 has this problem, just found this thread and was hoping since the '09 they would have corrected this problem!

Got ours back on 12/4 - Replaced Slave Cylinder and Master as well. Full replacement as well as GTR Fluid and gaskets. Clutch feels great and seems to be good as new.

Well, time to add myself to the list...

2009 with 50,9xx miles on the clock. I noticed from start up that the clutch felt a little goofy, but I didn't think too much of it. I pulled up to red light and found that I had almost no pressure in the pedal, and when the light turned green, it wouldn't go into gear. I was able to push it off the road onto the sidewalk until I towed it home a few hours later (freaking morons folded my mirrors backwards and wrote in the dust on my car )

I've ordered the upgraded CSC from ZSpeed and an OEM Master, hopefully I wont find that I need a new clutch as well. We have lifts and good tools for rent on base, so hopefully I can get it all installed with no issues next weekend. I'm stuck riding my motorcycle until then.

Well it looks like this is my third CSC failure in 20,000 miles...

It's been 16k since the last failure so I was starting to get less paranoid and checking the fluid reservoir level less often. Well after my recent oil change I was scoping out everything else under the hood and found my clutch fluid reservoir empty down to the filler hose but not yet to the master cylinder. I topped off the reservoir with some fresh fluid but I can already see the level dropping with regular driving. Taking it into the dealer tomorrow hopefully. I will keep everyone posted on what happens.

Add me to the list. No diagnostic yet, but all signs are pointing to this being the issue. 09 with 27K, they're trying to rip me out of the warranty. All hell is breaking loose if they try to make me pay out of pocket. Consumer affairs got a call but have to wait until the diagnostic tomorrow. First steering wheel lock, now this. What's the average price people seem to be paying? I'm seeing prices all over in the thread.

When mine goes out I'm taking it to a friends shop and lifting it and changing it myself for a couple hundred total....I know, big talking, but I've done worse. I've read prices KyleBucket from 1800 to 1200 to have one changed out. I hope you get warranty, you should!
Most folks recommend ZSpeed aftermarket but that clutch slave cylinder is 300+ and the original is +100 or so.

Whoever got there stuff covered under power train, can you explain what part got covered? I went into my dealer and the only thing involving the clutch that was under the PT warranty was the bearing? They let me look through every piece on their computer, so they weren't BS'ing me. They are on my side because this is the 5th car they've seen alone with this issue, they said swapping the GTR fluid is a ******** way for Nissan to cover their own ***. I'm feeling more and more like I'm going to get screwed.

The beating is what you need! Another name for the concentri slave cylinder is hydralic throwout bearing! Its all 1 piece. However i did my own on jackstands on a saturday. Just go to harbor freight and get a 80 dollar tranny jack and a good set of extensions it really is an easy job. Dont replace under warranty with another plastic nissan csc get the zspeed one. That way you dont end up like these other guys replacing 3 or 4 times. Just my $0.02.
