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

Boost'dVQ

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.

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.

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.

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.

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.

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.

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

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.

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

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.

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.
