damn, thats so sh1tty... I'm sorry bro.

I think we should clarify by stating that there are two distinct issues being reported across the 49 pages so far; a completely limp clutch pedal - generally attributed to a CSC failure. This also means you have a leak which will be observable in a low clutch fluid reservoir from the driver's side engine bay compartment. Your clutch pedal is sitting on the floor board and you have to lift it with your foot.

The second scenario is just a Master Cylinder failure where the clutch pedal only returns 20%-60%. This is also problematic because the car is practically undrivable, at least in a safe manner. The clutch engagement point is about the first inch of release the clutch pedal. You better hope you don't run into any large inclines on surface streets. These issues have really put me off to the 370Z and Nissan in general. If they address it, I will reconsider, and would strongly consider continuing my long standing loyalty.

From what I learned from others who have either had problem with CMC or CSC, is that when one of the two fails you are better to replace both at same time. Also going to a HD CSC is highly recommended. You may also wish to go to a "insulated" version of the short CLUTCH line so as to ward of heat to fluid. This is the second time my OEM CSC has failed. Never again will I buy a OEM CSC . The Nissan part is crap!

for EVERYONE that has experienced or even are concerned for yours to go out give Nissan North America a ring and tell the rep you're issues or concerns. 1-800-NISSAN-1 and file a complaint with the NHTSA here https://www-odi.nhtsa.dot.gov/Vehicl...nt/index.xhtml

I only tried to count those with the CSC failure so I skipped several that had confirmed it was the CMC and not the CSC

Ok looking for some opinions. Recently my clutch has been making a grinding noise just before engaging fully in 1st and 2nd gear. I took it to a shop and they said sounds like throw-out bearing. I believe we have the CSC instead of a traditional throw out bearing. Has anyone seen this symptom of the CSC failing or could it be something else? Thanks in advance.

I read that as you went back with a CSC. OEM or HD from ZSpeed?

FYI the elimination kit just replaces the CSC. The reminder of the clutch system remains the same.

I have no idea how you get "I went back with a CSC" (whatever that means) from "I had the entire clutch assembly replaced." :confused:

Am I maybe using the wrong terminology? I don't know anything about parts, but "clutch assembly" is what the shop called it. Whatever parts make up a clutch in addition to the CSC and CMC, they all got replaced.

Once again, I didn't do an elimination kit.

If you don't know what was included in your new clutch assembly, it's possible the shop just replaced your old CSC/CMC with another oem CSC/CMC. If it is so, you're at risk for another failure later on. May be worth to check your invoice for the parts listed :tiphat:

Z's and G's prior to 2007 (before the HR engine) used an external slave cylinder with a clutch fork pushing on it. This is pretty easy for maintenance because there's no need to drop the entire transmission to service the slave cylinder. With an internal slave (CSC), it pretty much lightened up the clutch effort. Lots of cars use CSC nowadays, but all of them eventually face the same issue with leaking and whatnot. The Valeo-sourced CSC body is all plastic, which is one of the factors contributing to these problems. For mine, the o-ring on the piston slipped off. I don't even track my car, drag raced, or even dumped the clutch. There was never a situation where the pedal sunk itself to the floor other than the stiffness in the winter.

Anyway, the elimination kit ditches the internal slave for an external and fork setup.

Simply create a spreadsheet and share it on Google Docs. If you like, I can edit post #1 to include a link to the document.

Thanks.

If you haven't done so, please take a few minutes to write a complaint on NHTSA via the link I pmed to you. It's our only way of getting nissan to step up and fix this.
