I don't think there's a rhyme or reason on if or when the CSC fails. Some people get it early on, some people get it later, and some never get it at all. I had a '07 350Z that was prone to the CSC failure, but mine never did and it was the original (bought her with 5k miles and traded her at close to 90k and held up strong).

For the record, it sits in the garage and off the driveway. I wanted a Z in the 90s, some 20 years later I bought a 2014 with 20,000 miles on it. But I have two kids, and I need the space in my truck almost every day even if it’s just me. I don’t drive much in general, since I work from home. So, it’s really hard to get any miles on it.

I drove it about 5 miles tonight to cheerleading practice, it started to get a little soft but after a few more shifts it was back to normal. Maybe it’s time to go.

So your clutch pedal goes soft and then back to normal after a few shifts? I have the opposite issue. My clutch starts off normal and then pressure gets softer as the engine warms up and then have to top off the clutch fluid. I'm just trying to find the time to replace everything, but in the meantime, I just drive her once every 2 weeks to get the oil running and to avoid flat spots on the tires. I guess we are of the lucky few where we get a warning that the CSC is on its way out.

That is exactly what my symptoms are, with all three of my Nissan’s that have had a failed CSC. Two of them left me stranded when it finally went to the floor.

There is a trace of failure and is in the composition of the clutch reservoir line. This line deteriorates and starts to introduce that goo into the system.

If this line is replaced(folks use motorcycle hoses) it will increase the chances of longevity by a lot.

Remove some fluid out of the reservoir and save it.
Over work the pedal on low fluid and it will do it

HOWEVER

Any of these advices have the possibility to affect the MC which if not covered it might fail faster than the CSC.

So technically for total failure you cant just have a dead pedal.
Just a dead pedal would technically mean MC only and they might deny it.

Depending on the dealer it might need to be a non working CSC with leaking fluid alone or a failed CSC and MC at the same time.

Many dealerships treat warranties as individual replacement since it doesnt pay the tech **** and they definetly dont go around recommending additional stuff that the customer wont pay for.

Being that the MC receives all of the work and only the MC at fault for CSC failure due to introducing debris into the system it means that the MC is usually the one to fail first and it might be your problem.

Unless there is some moist areas by the transmission your issue is a failing MC and not CSC.
