ok thanks brother.

Sorry it depresses you. "Tip For The Day"- check your clutch fluid level at least every other Fill-up. If it gets low it could be symptoms of CSC Failure. Don't get stranded like so many of us have & required to be towed!
:icon18:

2009 370z with 67k miles.

Master and Slave cylinders were replaced at 30k miles under warranty. ECM replaced as well in that time. Guess what? My clutch pedal only returns 40% of the way. I will never buy another Nissan again and will make sure my friends and family are aware of how unreliable their cars are. This includes "premium" models as well. I was considering upgrading to the GTR but not after this.

Does anyone know if Nissan has ever made any "official" statements about the CSC failures that so many of us have experienced? Or is trying to get a answer from them like Beating a Dead Horse?
:horse:

It's only been a couple of weeks, but after reading some of the newer posts in this thread I think I'm glad I went for the clutch assembly replacement. Everything feels great (knock on wood), I'm used to the slightly heavier pedal, and most of the new noises have gone away. What's left now is some transmission noise in first and second, but the mechanic thinks that's likely because they upgraded my transmission fluid and it's thinner than what Nissan originally had in there. He said if the noise really bothers me he can put thicker fluid back in and see if it helps. I'll wait another week and see how much it still bothers me (it's a light grinding/scraping sound; right now I'm leaning toward having him swap out the fluid).

I had an '02 Nissan Sentra -- manual, base trimline, all stock -- for four years and I never had a single problem. I even bought it used (in '04), and tracked it once (don't laugh!). The good experience I had with that car was part of why I didn't hesitate to buy my Z in late 2013. It's been a series of disappointments with this car, though: first the known track issues (oil/brake overheating), now the clutch issues. :mad:

Sticky: 370Z Clutch Pressure (CSC) Failures
 

Did you upgrade the clutch/flywheel when you did the elimination kit?

The lighten flywheels make a ton of noise. Mine sounds like a diesel F250 in first at low rpms.

If you are going to change fluids, Redline MT85:tup:

What brand/weight light FLYWHEEL did you choose? Pro's vs Con's - do you think the performance gains out weighed the noise issue?

Z1 Full Face with their lightweight flywheel. This transmission is noisy anyway so I wouldn't prevent doing something because of noise.

As for performance it's hard to say cuz I only had it a couple of weeks before I put the turbo on and obviously the performance changed dramatically after that. It did take a little getting used to because with the lighter weight the rpms drop off quickly when you engage the pedal. I had my tuner bump my idle rpms to 950 to compensate.

As far as I know, Nissan never did addressed this issue publicly, even though people have been complaining about cscs failure since the 350z were still in production.

I wish every person who been affected would file a complaint with the nhts and make their posts go viral all over Nissan's fb and tweeter. I am sure that will at least their attention to start acting on this subject seriously.

Five years later and still no recall. People are getting stranded on a weekly basis. Nissan still doesn't give a single **** about Z owners. So as I said it before, **** NISSAN.

Totally agree with you. :)

Nissan doesn't see it as a safety issue so even if people complain? They wont do anything about like the 350 before us.

So yes this is a beating the horse topic, and part of the negatives of owning the Manual version for some and not a majority since it's a hit and miss issue like other quirks the Z is plagued by.

Just so I know, what do people do if they get the clutch pedal to the floor? Just trying to prepare for the future.

Any quick things to do to get it going again to drive it to the dealership? Let me know

Stay calm and lift the pedal with your toes :eekdance:

Best preparation is to simply replace it with HD version.

Waiting for it to fail will just leave you stranded since there is nothing to do once it starts to let go.

But you should pay extra attention if you start to feel it not feel normal as it will give a subtle warning as it start to deteriorate and finally fail.

It wasn't subtle for me. Backed out of parking lot, and it was feeling fine. Pulled out and got into 2nd, and it failed immediately. I barely had 1" of pressure to get it moving back before stalling several times.

Well when mine went to the floor, I pulled over and ran down to the gas station and picked up some brake fluid and filled up the reservoir.. then pumped the clutch to get the air out while constantly checking the reservoir to fill it back up until it was decent to drive home...

Ordering my HD CSC and other parts from Zspeed on Monday!

For what it's worth... It's also a common issue on 6 speed manual Tacoma's and FJ Cruisers.

My X-Runner was on the way with the throwout bearing squeeling, People have complained about similar issues with their trucks just being off the dealership floor for a few months. Every car has it's weak points... But it's still ridiculous no less.

I posted this on Nissans facebook page

and got this response
Anyone else care to weigh in on the subject in a PM to Nissan?

EDIT: Here's my novel I sent to Nissan... at the end I included my contact info but I didn't copy that to paste it on here.

"I am happy with my newish to me 2009 Nissan 370z that I purchased through Carmax with 25k miles for the most part... But a few weeks ago as I drove 50+ miles away from home to go on a date of all things my beloved Z failed me... After picking up the date we got about 2 miles from his home and as I was leaving a stop light to turn right on a red the clutch pedal fell to the floor. I was able to pump it to get it to move but not after stalling about 4 times in a panic since I was in the middle of the intersection with oncoming cars. Fortunately we were not hit and I was able to limp it to nearby parking lot where I had to wait 2 hours for "AAA", Ultimately ruining my date that I have yet to make up for and a weekend of trying to figure out why my beloved Z failed me.

The very next morning (saturday) I looked into scheduling an appointment with my local Nissan Dealership (Tracy, California) but online scheduling said they were booked until Tuesday. I didn't wan't to leave my Z outside (she's spoiled by being garaged) and conveniently I have a buddy I made by using his expertise before on my previous Toyota Tacoma X-Runner (That I had for 120K miles that required nothing but maintenance or regular wear items I might add [like brake pads, rotors, tires, filters and oil changes]).

The place my buddy works at is a independently owned mechanic shop called Tri-Valley automotive in Dublin California... They are ASE certified and all that stuff. But before that morning came... I was up all night doing my own diagnostics on google... Having been able to in seconds find a thread on my Nissan 370Z forums explaining the exact issue I am having. Which is the clutch slave cylinder began leaking

http://www.the370z.com/engine-drivet...-failures.html

To my dismay I discover that this is a super common problem, My 370Z having only 31,239 miles at the time became one of the many on that thread, I counted over 50 before I got tired of counting not even half way through the thread... So I am sure it'll be over 100 with people that have far less miles than I have. After more research I find it's also on the late model 350z's and the 6 speed G37's.

I was able to get my 370Z repaired at the cost of $300 thanks in part for the aftermarket warranty I paid an extra $1800 for that I did not really think I needed (I really thought I would never use it seeing as how I'm a meticulous owner and the car has such low miles... and to be honest, never considered Nissan to build an unreliable car), A scan of the work order and receipt is attached in a PDF file here... I opened a case with the NHTSA and even after reading from there, I find that several people have had the same issue. I am urging people on my 370Z Forum to do the same thing and file a complaint there... I believe a recall, extended factory warranty and or something needs to be done to fix the problem. Aftermarket companies spotted this as a weak point in the design since it is made out of plastic and have made kits to completely remove the clutch slave cylinder or even as simply make the entire thing out of metal. It's only a matter of time if not already has happened that someone is seriously hurt or even worse, Killed because their 6 speed manual 350z, 370z or G37 decided the clutch pedal is more comfortable on the carpet in the middle of an intersection or highway rendering the car unoperable.

The info for my car is
2009 Nissan 370Z Touring/Sport/Nav
JN1AZ44E59M402001 with under 31,400 miles on it (no idea why they put down it has 31,503 on the work order when it left the shop [type i'm assuming]). "

**** Yes!! You are my hero for taking this step, BamBamZ! We have the power of social medias on our side guys! Everyone here need to do this, seriously.

I would even take it a step further and log your complaint with the NHTS then post a link on Nissan's social accounts with a brief description of your issue. If they refuse to act, we can make them react! Here is the linkHome | National Highway Traffic Safety Administration (NHTSA).

I'm in! Good post:D

So...it finally happened to me earlier this evening. I went out to start the car to get to the car wash, and found my clutch pedal already sitting half way in and I had to reach further down with left foot almost to a full extension to make contact with the pedal. I only had to press the pedal down about two inches to get it started. It felt weird so I pushed the pedal in again and I only get pressure toward the bottom. The first half of the travel had very little to no pressure at all! I tried lifting the the pedal up with my toes but it was very floppy...I then turned off the car and opened the hood to check my fluid and sure enough, clutch fluid is filthy, I can see a lot of black debris inside the resevoir, and my fluid level was right between the Max and Min line, so I had loss some fluid since the last time I checked it a couple weeks ago. I hopped back in the car and pumped the pedal several times and it eventually returned some some pressure but still not its full range. I then sarted it up and went for a drive...I was able to get into all the gears, but my clutch pedal still isn't returning completely to its normal position...maybe 3/4 only. Autozone was already closed so I'll have to wait until tomorow to pick up some brake fluid to fill it back up. I'm hoping by refilling the fluid will buy me enough time to get a new csc and mc in from Zspeed, and take it to my shop to swap it out, but my oem csc is definitely showing symptoms of failing. My Z is a 2011 and the current mileage on her is 25,465 as of today :facepalm:

This is getting ridiculous with so many of us having CSC failures. Nissan sucks! I received my new CMC, HD CSC , short insulated CLUTCH line from ZSpeed about a week ago. Since the transmission must be dropped to put in new HD CSC, I've also decided to take advantage of that by also putting in a new Southbend SS Quiet CLUTCH & new light weight aluminum flywheel. AAM Competition is doing the installation.

This is a common problem ever since Nissan switched over to these awesome Valeo-designed CSC in 2007 with the HR engine (e.g., 2007 350Z/G onwards). I sorta miss the old external slave and fork.

I have logged a complaint with the NHTSA before hand.

http://www-odi.nhtsa.dot.gov/owners/...5&refurl=email

I got this response from Nissan this morning...
I'll call in a little while and edit this to let you guys know how it goes, I just want to make Nissan aware they have this upcoming issue and the cars are failing by the dozen and hopefully they'll instate a recall and redesign the clutch slave cylinder to actually not fail within 4K-40K miles.

EDIT:

Spoke to a guy who had no idea what I was asking for, And that kinda confused me because I made it clear... It ended up being a request to find out how many cars were serviced to repair the clutch slave cylinder (which i was interested in but wasn't what i was asking for), He couldn't find that information then I explained that my concern is that the part is made out of plastic and many people have had this issue before so I don't know how long the new OEM part I had installed will last and that Nissan needs to make one out of metal and do a recall...

Suddenly they want to look at my car now, So I have to take it to the nearby dealership where they will inspect it... And consider replacing it with a metal part. I have no idea what the hell is going on at this point but just going to go with the flow.

I like your complaint and thank you sir for doing that. This is so frustrating to the point that I just want to go ahead and buy the aftermarket CSC, $$$$$ in labor and call it a day. I love my Z but its not enjoyable anymore because every time I shift I am thinking about the da*n CSC failing..... :shakes head:

We should ALL do the above ^ 1) Complaint and then 2) Call the number. See if 1,000 calls and complaints make NISSAN do something about this known issue.

damn... dude, thats sh1tty man. Keep us posted.

I was looking at putting in aftermarket too but I'm on leave of absence from work and workmans comp likes to delay their checks to me... So it hurt enough to pay the $300 deductible for my aftermarket warranty. When I asked my friend that works at the shop what kind of part he used (hoping it was metal) he showed me the OEM box. Before leaving I said "see ya in another 30k miles"

I'm expecting it to fail again, But not for another 20K miles or so.

Agreed!

The number is 1-800-Nissan-1

Then press 7 for consumer affairs, you'll get forwarded to a representative and just explain your concerns. That the current OEM part is plastic and is prone to fail so you're paranoid that it will.

Okay, so here's my dilemma...since my csc hasn't complete failed...yet (just loss some of its clutch pressure), should I even bother taking it to the stealership? Knowing how they treat others with the same problem in the past...they'll just keep my car a few days for "testing" then fill up my brake fluid anyway, or maybe flush it out and charge me for some GT-R fluid :rolleyes: I can just do this myself and not having to leave my car in their hands. This morning I managed to drive to work okay, although my clutch travel is noticeably less than before. Need your opinions what I should do at this point.

Edit: will be ordering new HD CSC and oem MC from Joe later today. Looking at their lightweight flywheel too, most likely I will throw that in as well. Can I just upgrade the hydraulics and flywheel only while keeping my oem clutch?

I'm thinking the course of action from Nissan is nadda until people start getting into wrecks. I don't get with the price of a brand new Z climbing you would think they'd switch to an improved CSC by now. Heck, the HD-CSC ZSpeed offers doesn't even break the bank, and that's not even bulk cost.

I sure Nissan knows about the issue though because there's a TSB out saying to "flush and replace with GTR R35 brake fluid" if the clutch fluid drains and the pedal goes to the floor.. So it's not a recall but if they see the issue that's what they are supposed to do.. except that won't fix the issue.

I agree with you. Usually the only time things get recalled is after people die. I attend a lot of car events with my Z. I'm going to add a large sign/poster stating "Nissan Z's have horrible CSC that fail & leave you stranded"! I will include photos of the failed component, my Z being towed, the transmission being removed from it, and receipts for parts/installation/Tow charges!- I will the take a photo of my Z displaying the poster at all the different car events/shows I attend and forward pics to Nissan, they're dealerships, & car event organizers, and also post to public forums.

So I put my complaint by calling Nissan Customer Affairs at 1-800-Nissan-1 then pressing 7.

One customer service representative (Located in the Philippines of course) opened my case and filed the complaint. It will be forwarded to somebody

Case Reference # XXXX3044.


Who is next?

nice..

Hmm...mine hasn't exactly failed yet, do you think I have some ground to submit a complaint? I'd like to but I'm wondering if they're just going to brush me off.

Here's a creative example what an individual did to send a message to United Airlines for breaking his guitar. 15 million hits! Any musicians/song writers out there?
