My clutch stuck to the floor about a year ago. After attempting to fix myself by draining, replacing fluid, then bleeding (used a generic DOT4 fluid) it lost pressure again within a half hour.
The dealership fixed it under warranty. They told me that the fluid had boiled and that this was a known issue due to routing of the clutch fluid line near the exhaust or some such.
The fix, and it has fixed it, was for the dealer to use a special Nissan Racing DOT4 fluid that would resist the heat -- ie not boil and aerate.
No problems with the clutch since.
However, I did start noticing a grind going into 5th gear a while back.
I brought the car to the dealer again last Tuesday. They called me on Wednesday and said "you need a new transmission".
So, I got a new trans, a new slave cylinder, and a new throwout bearing installed at no cost.
The new trans shifts like butter compared to the last one.
Anybody who is under warranty and is getting any sort of grinding while shifting should report that immediately IMO and get it resolved before the warranty expires.
The service adviser told me that when they drained the MT fluid from my old trans, that it had a lot of metal shavings in it. I think the 5th gear syncro was starting to disintegrate.
Heads' up MT drivers!

Would this be covered by the extended powertrain warranty?
Keep us posted Rochester.

Sorry to hear about that Rochester. You'll be covered under warranty for sure, if not fight it.
The CSCs are known to fail and you might want to inquire with your dealer if they would be willing to install an aftermarket part (ZSpeed HD CSC) that you supply and claim the labor under warranty. It's worth a shot considering the OEM CSC will likely bite the dust again.
Many people and ZSpeed recommend replacing the master cylinder at the same time as the CSC. I believe the train of thought here is that the fluid is contaminated with CSC crud/seals and it affects the seals on the master cylinder.
Also, I believe the reason they recommend DOT 4 fluid over the original DOT 3 that was in the system is that the clutch hose passes right by the driver's side cat, these things get hot and will heat up your fluid. DOT 4 generally boils at a higher temperature and thus gives you more margin before your clutch begins to feel spongy.
My dealer forgot to move the stock insulation over the ZSpeed HD CSC stainless line that that passes by the cat, I am pretty sure this is why my clutch feels different (might even describe it as crappy) after long drives. Little pissed off about this, but I'll fix it up this weekend

Oh. Right. 
Welp, doesn't really matter in my case with only 18K miles on my 2011.
And I just heard back from the dealership. They confirmed that the clutch slave cylinder blew out, as suspected. The new CSC won't be in until tomorrow, which is a moot point since I'm going out of the country on vaca.
As far as frequency, he said that in the 16 years he's been working at this dealership, he's only ever seen this happen once, on a 350Z. So while the problem may be "common" as seen from the POV of online enthusiasts from all over the world and a decade of comments... in the real world, not so much.

Exactly. Also, there are a disproportionate number of 6MT owners on the car forums than there are in the real world.

So I'm getting something I have wanted for a while - midnight tails ( painted on the inside) with evil iron man leds and custom turn signal, the question is what tools will I need to remove the tailights, I know it must be easy just never really removed mine yet, so I wouldn't know what tools I'll need. Any help is appreciated, thanks.
