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

Since I've been working from home for the past couple months, I drive my Z about once a week to just get out and keep it running well. I may have felt my clutch acting funny a couple months ago here and there, but nothing significantly. On Saturday, all of a sudden, the clutch was very week and I was barely getting any pressure back. I am well aware of the CSC issue and it is the main reason why I got it CPO, among other reasons. There were two times while I was driving on Saturday that the clutch wouldn't come back up, so I had to lift it with my foot. Pumping it would kind of help, but driving on the highway did not help. I quickly turned back around and went home when I noticed things getting bad. I actually even stalled at a stop sign because I wasn't getting any clutch feedback...and, yes, I know how to drive stick very well. Just to make sure it wasn't a leak, I checked the fluid level and everything is topped off, so I guess this is good news and bad news.

I just find it so interesting that there is no common factor among those who have been plagued with this issue. It spans from brand new vehicles to vehicles that are crossing 60k miles with all kinda of different background stories. It's very discouraging that Nissan hasn't done anything about this, even with a class action law-suit, which I understand can be pointless at time, but it really does shed light onto the matter. Also, I do not think it is a coincident AT ALL that Nissan changed the clutch set-up to an Exedy system - I haven't really heard any issues with this newer system, but maybe you all can chime in.

Anyways, I am obviously trying to get Nissan to pay for this is ridiculous manufacturing/engineering flaw, and I've read the PITA stories that people have gone through, but I'm giving it a shot. I had one local dealer basically say I'll have to pay for everything and that they don't have many Zs that come through. The next dealer I spoke to, the lady knew what she was talking about and assured me her GTR tech would diagnose my car and she even waived the $150 fee, which I appreciated. She also mentioned it sounds like it would be covered under my CPO warranty if it isn't covered by Nissan. She said Nissan has one of the best customer services...sure, I'll go with it. I heard back from the tech today and he said the "CLUTCH SEEMS OK SINCE HEAT IS A FACTOR IT IS POSSIBLY THE RUBBER LINE THAT GOES TO THE SLAVE CYLINDER." So, before removing the transmission to actually see if it a CSC issue, he wants to "REPLACE LINE FIRST AND BLEED SYSTEM AND RE-CK MAY NEED SLAVE CYLINDER ALSO." This is a $481 bill to me and they will not cover this. So, what guarantee do I have that I pay $481, the new rubber line doesn't fix the issue, and I have to pay the $1-2k it costs to replace the CSC. Sounds like I'd be really effed then. Also, do you guys/ladies think they would replace it with the new exedy system rather than the same plagued system?

I've called Nissan NA to speak to them about this, but apparently their lines are busy, so I haven't been able to actually talk to them yet. Any advice? I'm currently w/o a car and have been hitching rides with my wife.

Thanks!
