Not only did I have a CS failure (also requiring the entire clutch assy to be replaced) I had massive oil consumption (and wildly fluctuating oil temps) which resulted in a new long block.

The car has been out of commision over 40 days. Have had ongoing check engline lights that are still unresolved. I'm still contemplating lemoning this piece of junk or trading it in and taking the hit.

My car is a 2009 Nismo, off the lot 5/30/10 currently 8500 mi on it.

I was driving to work today and was stopped at a light to turn into the plaza I work in. When the light turned green the clutch did not come off the floor and the car almost stalled out. It then popped up and the car lurched forward and regained rpms. Then clutch then refused to pop out any father than the engagement point without pulling it with my foot. I limped to the nearest nissan dealer shifts getting harder and harder to pull off and the clutch sinking lower and lower. Once I got into their parking lot it would not go into gear at all and I beached the car into a row of parking spaces. The dealer then attempted to feed me a load of **** about how the clutch was probably bad and this would not be covered under warranty and then proceeded to insult me for not buying the car from them. (They never had any Nismos in stock for the 3-4 months I looked ofc)

I asked if this is under warranty, and they say no, b/c its a clutch. I seriously suspect is isn't the clutch. But they want me to spend $600 for them to take my tranny off, and do an inspection on the transmission. I think that is ridiculous. Did any of you have to pay for this? Also how in the h*** can a clutch and assembly with labor be over $2600?? That is crazy!! I am calling the dealership I bought the car from today, I didn't take it there originally b/c I live almost an hr away for that dealer....:mad:

I am expecting what happened to chrono's to be what they tell me. They are going to assume I am retarded and say the entire clutch is broken after 8000 mi and try to charge me to fix it. The service woman was telling me that people drive this car for performance so the clutch plate, pressure plate, some bearings (not covered) always break around 10,000 mi. Are people really that stupid? I just told her I was sure it was a covered part and that I wasn't worried. You would think dealerships would want to convince customers to return to buy from them not another dealer...this is my second nissan now and I will never return to this dealership to buy anything.

Ouch, hurts to read this. Hopefully the 7AT won't give me any issues. My S2000 has been bullet proof for 50k miles and the Z should be no different. I can understand Nissan having some issues with a new model but asking customers to pony up $2,600 for a new clutch or $600 to inspect is rediculous.

I wish you all the best. You don't deserve this...

they may not of broken anything.. some techs make **** up just to make more time. I work in a service dept and see it all the time.

So this just happened to me on the track of all places. Z Roadster 10k miles 2010. Seemed to be heat related, as it only started happening after multiple laps in 100+ degree weather. Clutch pedal stuck on floor, could be popped up by hitting it with the side of my foot for awhile, but eventually I'd pushed the car to the point where the pedal remained on the ground, couldn't be kicked up and wouldn't disengage the clutch....decided to pit at that point...after about 30 mins of cool down it was back to normal. I thought i had boiled the fluid the get this level of hydraulic failure until I found this thread.

sarmyth 05-21-2011 12:29 AM

Dealership tells me that Nissan recommends changing out the clutch master and slave cylinders. Apparently this was a problem on the 350z but I'm the first one he's seen with the issue on a 370. Nissan says the CSC can leak, is part of the tranny and requires the tranny to be dropped for replacement. The new part is not an up'reved version, but apparently the problem goes away once things are switched out.

Sounds like a quality issue to me.

I still think I boiled the fluid though, had 260 on the oil temp w/34 row cooler up front with >100 degrees outside on the track. Will be insulating the line and switching to good DOT 4 after the swap.

Fastfatdude 05-31-2011 08:07 AM

Mine failed at 140miles on the odometer.
When i collected the car only had 10miles on the car.

Dealer fell over each other getting my car back on the road.
Replaced the csc, and a new clutch and housing.

Gave me a murano as a loaner for a day, gave my car a free polish and extended free servicing till 20k .

They must be real concerned about their reputation...

Keeping my fingers crossed...

EVOnomore 06-17-2011 01:10 PM

Any issues on 2011"s??My Clutch feels weird.Noisy when the pedal is not engaged?

noisy transmission when clutch is pedal is not depressed is normal

Glokwork 06-20-2011 05:39 PM

After seeing this thread I want to check the fluid level on my z. I just went under the hood for a minute because its raining but I didnt see it. Where is it located?

Let's sticky a thread that lists owners who experience loss of clutch pressure with the pedal sticking to the floor. Please include the last 6 digits of the VIN, since Nissan support requested this number when calling for support. Hopefully we can gather some failure stats.
  • VIN: 406164
  • Purchase Date: 04/17/2009
  • Occurrence Date: 09/14/2010
  • Occurrence Mileage: 16,158
  • Clutch Type: OEM
Summary:
Getting ready to leave work, warmed up the car, pulled around the corner of the parking lot, and the pedal sunk to the floor when attempting to engage 3rd. The morning commute was normal, and there has been no real complications other than random shudder when going into 1st. The more I press it, the further it sunk without returning. A twitch of the foot would kill the engine. Clutch is stock. I never dumped it, burned out, etc. Only a few spirited driving once in awhile.

Conclusion:
[09/15] CONFIRMED CSC FAILURE, and a new part will be overnighted. The failed part must be returned to Nissan, but I asked the service advisor if I could examine the CSC and take some photos to benefit the community in regards to what's causing the failure.

[09/16] Car is still at the shop. The tech spent the entire day removing the transmission. Hopefully it'll be ready tomorrow afternoon. On a side note, I requested them to check out the brake switch and re-align it to resolve part of my throttle delay issues.

[09/17] Got the car back. The tech said something about fluid leaking out of the CSC. From looking at it first hand, it looks like it is leaking from the inside indicating o-ring failure. He said the last car he worked on had the same symptoms, but it was the master cylinder that failed. He was surprised about the condition of my clutch (clean) because he wonder if I ever drive the car hard. The car seems to drive a bit better, softer engagement, less play, and so far no signs of judder.

Part Number: 306A1-JK40D

[EDIT] Found a term for the random "shudder." It's called clutch judder:
WikiAnswers - What makes a clutch judder


Yeah.... so? Sounds like just bad luck. Could have happened to anyone.

fuct 07-25-2011 09:21 AM

hi my name is nick and i also have a stick clutch pedal....


haha, but yea 50% of the pedals play has lost pressure. i checked the fluid level and it was at the MIN level. topped it off and it felt about the same. i tried to pull out the old fluid and replace with some new dot 3/4 fluid. im not sure if i have all the air outa the system. it feels the same with the pedal only feeling normal during 50% of its stroke.

does anyone have the proceddure for proper clutch fluid bleeding on our cars? thx in advance

oh im at about 23k miles and baby the car.

quicksilver08 07-31-2011 12:31 PM

Lost it in my Infiniti around 25-30k miles. Worked fine and then I went to stop and it sunk to the floor. At 41k now and if the car sits overnight the pedal sinks almost all the way to the floor and it takes about 25 miles of stop and go to bring it back up.

Did you get the master cylinder checked?

quicksilver08 07-31-2011 01:16 PM

They replaced the master cylinder, slave cylinder, and clutch pedal assembly. Said the clutch looked brand new and asked if I ever drove it.

Haha same here. At least we didn't suffer the burnt clutch issue like some owners of '07+ 350Zs had. I hate the "free play" feeling of the clutch engagement, so I can't wait to see how well an aftermarket CSC will perform.

quicksilver08 07-31-2011 02:58 PM

Ditto. Mines to the point that it drops till its about an inch off the floor and then it disengages the clutch.

Boost'dVQ 03-25-2012 06:16 AM

2011 My clutch just went out around 3 in the morning driving home, had to get it towed since every time i came to a red-light it would stall because the clutch was still engaged half way. 76xx miles

Boost'dVQ 03-27-2012 10:09 PM

Update: Took it to the dealership, they took the tranny out and found that the clutch assembly was saturated in brake fluid, they said they're changing the slave cylinder and the clutch assembly out all under warranty. Dealership said that the clutch had a 12mon/12,000mile warranty on it.

Big J 04-17-2012 08:39 AM

Well I think my slave cylinder died yesterday as well. 2009 with 21,xxx miles. The clutch pedal is just dead. I'll update when my Nissan dealer calls me today.

Footloose301 05-06-2012 06:26 PM

I had problems yesterday while doing some light Auto-X. I never launched the car at all and never shifted from 2nd gear. It stuck 8-10 times and I'd have to pop it back up with my toes. I'm at 33,XXX miles.

sounds like the CSC. :\

if nissan removes your bellhousing ($400) and determines your clutch to have excessive wear they wont replace anything under warranty. just a heads up....

since the CSC is to be replaced every time the clutch is replaced, if your clutch looks bad then this will just be considered routine maintenance and not a CSC failure. lets hope your clutch looks good, then it should be covered.

red6spd 05-07-2012 11:53 AM

Thats such BS. What stops them from just saying "Well the Clutch is to worn out so it must be your fault" Good luck to everyone.

Trilitheum 05-15-2012 08:39 PM

Pretty sure I just had my CSC go, car is less than a year old. The pedal is on the floor and there is a nice puddle of clutch fluid under the car dripping out of the bell housing, needless to say the clutch reservoir is empty as well...on the phone with Nissan road side right now...
I had about two gear shifts from when the pedal would come up to 50% and I brought it back up with my foot, until it was on the floor and I could no longer disengage the clutch and it stalled.

:shakes head:

anthonyy 06-20-2012 02:43 PM

I have about 12k miles on the car, owned for less than a year, and purchased new.
Noticed that the clutch fluid was low and went to dealership. No real change in feeling from clutch pedal. Throws seemed a little more resistant than usual.
Dealership confirmed that master cylinder was leaking.
Under warranty they are going to replace the clutch master and slave cylinder as well as the hydraulic system.

youseenothing 07-05-2012 08:08 AM

Had to drop my 11 Nismo off yesterday because of the clutch sticking to the floor and having about 4-5" of play suddenly. Didn't look at the fluid levels but should know today what the deal is. I only have 9300 babied on it. I will post an update once I hear what the deal is and what is being done.

sounds like you will be fine. they should replace the CSC under warranty.

youseenothing 07-06-2012 05:36 PM

Well they replaced the slave cylinder. Said everything else was fine. Seems to be fine now. I will give it a couple of days driving to know for sure.

TacoZ 07-06-2012 07:17 PM

Dropped mine off today at the dealer. This is the third time in 3 years it has gone in with clutch problems. This is my first Z and I'm hoping that this isn't a common problem with all Zs.

370Z Purist 07-07-2012 06:25 AM

2009, 12K miles. Suddenly became incapable of shifting into gear. Had problems when cold started, after being driven, and also after being stopped, while warm. Bringing into the dealer today, likely towed in. Hearing about how the OE CSC is trash, will probably do a full swap. I can count how many launches I've done in the three years I've owned the car on a single hand. Hopefully they won't dismiss the clutch as being "too worn." Yes, just ignore the leaking fluid and say my clutch is too worn.

EDIT
Spoke to the dealership, who has first quoted me half an hour of labor for "inspection," whereupon they told me they cleverly deduced it was the clutch. Yes, the fact that the pedal has no pressure definitely points toward there being some kind of diff issue.

Quoted me 780 dollars just to drop the transmission. Seeing as my warranty just ran out last month, they're shafting me for repairs.

Bking 07-09-2012 10:27 PM

This just happened to me today. Just got it towed to a dealership.
Which warranty will this be under? Powertrain?

I have an aftermarket catback exhaust on my Z now. Will it void the warranty?

Thanks.

I think they put it under general warranty (3 years/36k) because if it was under powertrain, 370Z Purist would be covered (5 years/60k). it's not a transmission failure, that's probably why.

I believe the CSC should be covered under the powertrain warranty as it is not a wear item like the clutch.

This is what Nissan says of the Transmission under powertrain warranty.

TRANSMISSION AND TRANSAXLE
Case and all internal parts, torque converter and converter housing, automatic transmission control module, transfer case and all internal parts, seals and gaskets, clutch cover and housing, and electronic transmission controls.

All hydraulics are covered under basic warranty only. Powertrain mostly concerns larger items such as driveshaft, differential, transmission, engine.

Just checked my infiniti elite coverage - looks like both the master and slave are covered. I imagine if you have a nissan extended warranty, coverage would be similar.

christian370z 07-13-2012 02:34 PM

Having clutch issues: no fluid loss, pedal is not sticking, no additional drivetrain noises, goes into gear fine.

Symptoms: a pop sound when shifting, after there as a much softer clutch pedal, less clutch engagement, some clutch slip.

Going to the dealer tomorrow AM so will report back when they let me know their findings.

Jsolo 07-13-2012 03:09 PM

Christian, it almost sounds like your clutch is worn. How many miles on the car?

An issue with the CSC or master typically does not result in slippage. If you're in 3rd gear, ~30-35 mph and you nail it, does the rpm increase proportionally to the speed? If rpms shoot up way quickly, then it's definitely a worn clutch. Not covered under warranty unless you can convince them it's due to some other defect.

9,000 miles, if there is something wrong with the pressure plate or slave, it could prevent the clutch from fully engaging. The clutch is definitely not worn, especially since this change happened immediately after that pop during a normal shift.
