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

Aardwolf

RJM pedal reduces the chance of failure by minimizing excess clutch cylinder stroke and therefore seal wear.

Hey fellas,
My 370z was purchased two Saturdays ago and clutch went out on me last Saturday. First felt soft and spongy then was gone after I came to complete stop. 2010 with 15k miles. Have not found out exact problem yet as it is still in shop being fixed under warranty. I told them what I had read on these forums and am hoping for a legitimate fix. I will let you, they have had 370 since Wednesday so it should be soon.

Driving to work yesterday my clutch peddle hit the floor. I was barely able to make it to work. Had the car towed to Oakville Nissan where they diagnosed it as a the CSC. 1200 later and the car was repaired. I saved the parts if anyone wants to see pics. Again my car has 30,000 km on it and is a 2009. This part was not covered under my drive train warranty which is still active until april.

I was on my way back home today. The clutch was spongy at first and then got worse. It never came back when depressed. I stopped at the red light and stalled 3 times to get it move. Luckily it got to the parking lot. It's now towed to the Nissan dealer and wating for estimate. Powertrain warranty ends in 03/2015 so hopefully it is covered. The Z is 2010 with 21k miles.

Update : The dealer said it won't be covered under warranty. They said the clutch won't be covered by the Powertrain Warranty. Fortunately, they said that there's air in the hydraulic system. They just bleed my clutch and it's working again. They said if it happen again, I have to rebuild the clutch which cost 1500 for parts and 1000 for labor.

so does the power-train 5-year/60k-mile warranty cover the CSC or not?

Short answer - it depends on the dealership. Almost ALL say it isn't, but there are a number of people here that have had it replaced under warranty. My dealership told me clutch parts only have a 12,000mi warranty. However, somehwere in the warranty information it does specify that everything within the transmission/bellhousing besides the clutch disc is covered under powertrain warranty. The CSC is within the bellhousing. So, contradicting facts.

Short Short Answer - don't count on it.

As an aside, my dealership told me over the past few months they've had 5-6 CSC failures come in.

im looking at possibly getting a z in the spring. anyone who's had a csc failure, would that turn you off from purchasing one again?
also what's the rough cost if the dealer wont cover warranty to replace. I dont really have the garage, tools, or skills to open a transmission and fix it myself.

I wonder if my old regional Nissan rep is still around. I want to call him and open his eyes a bit.

1,500-1,700 I'd guess.

If I had known about the issues with this car (CSC, clutch pedal fracturing, oil overheating, axles making noise, transmission overheating, diff overheating, steering lock, horrible paint) I would have at least tried to get it for much less.

I would say more like $800-1000. A shop could probably get it done in 6-8 hours.

having this issues, with my Z...
clutch is all the way to the floor, no pressure, bleed the thing couple of times no pressure..
How far is it 2 tackle this job?

CSC most likely. Are you asking how difficult it is to DIY? Are you mechanically inclined? I did it with the necessary tools including a $120 transmission jack from Harbor Freight and the help of a friend who has done a lot more mechanic work than myself. It took us a weekend, pretty much two full days, from start to finish. Neither of us had ever removed a transmission before. We didn't have any problems, but it was long and somewhat tedious. Not sure I would do it again. I saved probably $800-1000 in labor costs, so I'm not complaining about it. But I think when the stock clutch finally goes, I'll be paying someone to replace it.

I just swaped mine out with a beefier one. It took me a good 11 hrs of actual work to drop, swap and up again. It was a tough job. I had a hand help hold this and that once in a while. Get them car in hover moved *** high as it can go. Get a good pilot bearing puller, use the jack bar fire extra leverage, have have all the parts you need and plan for it to be a good 2 day job.
