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

boosted180 · 01-16-2020, 10:59 PM

Any shops in Socal you guys would recommend to get the CSC replaced/ upgraded? I'm in Long Beach.

Interesting about the class action lawsuit. Any of you part of it? Trying to decide if it's even worth the trouble to join...

It's a bit of a drive for you, I took mine to Fast Intentions in Simi. The cost was the same as going to Nissan, but it is a much better clutch and if you plan to boost or track, it'll last for you.

Good luck

The only people that win in class action lawsuits are the attorneys. The company usually get off with a slap on the wrist or at worst a minimal fine, and the attorneys get paid fat. The customers who got screwed essentially get nothing. Waste of time and resources...

I just purchased 370z and want to replace my csc now before it goes out on me. Is it better to go with the heavy duty one or eliminating it?

Consensus is to eliminate with the CMAK.

Hey guys, had my car for couple months now. Recently started to feel "softer clutch feel" after couple harsh driving. Fluid was black... Changed the fluid for stoptech 600 fluid. It's still doing it but less dramatic.

ramblinrose · 05-03-2020, 03:07 PM

2016 370z with 20,000 miles. Csc failed. Replaced with Z-1 Elimination kit. Total cost 1,300. Very insensitive of Nissan not to fix an ongoing problem.

*Sigh*...2015 370z Nismo Manual. Just passed 35k miles and has been rock solid since I bought it almost 2 years ago at 8k miles...until this past Saturday. I absolutely love this car and it has been a dream to own one.

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!

I went thru all of this. Both with my 06 350z and my current 09 370z. On the 09 it was happening at around 18k miles. Do yourself a favor... I have a few words for you. And I know you'll be happy. Joe at zspeed. And Ryan at rjm performance. Get this

The clutch master cylinder normally causes this issue if there are NO fluid leaks or loss of fluid, Master is $99 on our site, If you are tight on cash at the moment, replace the master and re-bleed the system first and your issue should be resolved until the slave dies...

Thanks for the prompt response from both of you. I've heard great things about both companies. Is the adjustable clutch pedal from RJM necessary or just a nice to have? I don't track/race my car - just DD and the occasional spirited driving on highways. I'll definitely need the complete clutch flywheel system as I don't want just a quick fix. Fortunately money isn't tight and I prefer doing things right the first time, but I was just really hoping to have Nissan cover this. My birthday is tomorrow too - THANKS, NISSAN!

BTW how much is it to have this done in a shop - on average?

Both are neccesary in my opinion. I just got the pedal installed last week. Had the zspeed cmak and clutch for about a year? Wish I did both sooner. I'm a casual street driver. The stock pedal is just too finicky for me.

3:20 mark for a better explanation. But I can assure you, shifts, especially 1st to 2nd are wayyy smoother with this pedal. And the clutch feel is much better.

2 hours for a good mechanic to install the pedal. And some time afterwards for you to try the pedal and then make adjustments. So maybe 150 to install? I paid $550 in nyc for the complete cmak and clutch install.
