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

Zeto · 12-01-2010, 01:50 PM

Ok my Z is at the dealership and they said they would replace the pressure plate and clutch. Should I print out this thread to show them a trend and the part number?

6SPD_FTW · 12-03-2010, 02:04 PM

This loss of clutch pressure is a recurring thing that occurs on 05+ V6 Altima's, MT Maxima's, the 350's and 370's. My previous 2007 Altima 3.5SE did this crap 2 times in 40,000 miles and that's it.

It's a pretty routine thing, from the research that I've done, that the clutch pedal will sink to the ground, loose pressure and will remain that way for varying amounts of time. It seems like regardless of which vehicle it is, the pedal will return to normal given enough time. Some just have to sit for a while longer than others. The Altima's and Maxima's were narrowed down to something in the master cylinder (most likely). Even on older vehicles that had a traditional slave cylinder/TO bearing setup, this failure still happened on them.

If the CSC fails, it would stand to reason that the clutch pedal would still return to normal position when released. There's a big spring on the clutch pedal that pulls it back up. Of course Nissan uses some funky fulcrum/pivot point in their clutch pedals which I think has a big part to do with this.

Is there a solution?

Ok guys these are the items with the part numbers that were replaced. They were all covered under warrenty. Clutch feels brand new. Hope it helps.

ouch looks like they broke a bunch of your flywheel bolts and had to drill them out and re-tap the threads, shitty. It should feel brand new as everything was replaced =]

Looks more like milking Nissan for more time by saying the bolts broke... The bolts didn't break

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.

just dropped off my car at the dealer. car's at 11.5k miles
been having issues with my clutch being stuck, once i was even unable to accelerate. and recently, having trouble shifting. in order for me to get in gear i had to use A LOT force to even put my car in gear,
oh fluid was REALLY low also

dealer looked at it yday, took in my car for further observation.
was talking to a mechanic he told me that he knows what i'm talking about. happened to him while driving a nismo

i'll keep you guys posted

lazer_Z · 02-03-2011, 04:35 PM

just got my car back from having these issues. i have 3,412 miles. been going on since about 2,500 miles. they replaced master cylinder, all lines, and slave cylinder

zilent_jay · 02-08-2011, 06:26 PM

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.

11Thumper · 04-22-2011, 02:21 AM

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...

sarmyth · 05-07-2011, 01:56 AM

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
