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

Well i've now had both CMC and CSC done twice in 4 years, which for me is about 275000kms.

Hot or cold brake fluid doesn't matter, when the plastic O ring in the CSC fails, it fails. The reservoir will be empty and the fluid will drain out. The Service bulletin requires dealerships to fill the car with Dot 5 or Nissan GTR brake fluid to treat the symptoms of a sticking clutch pedal. This may prolong the problem, but it does not correct or solve the problem. The design of the part (using plastic parts) is the reason for the on-going CSC failure....it doesn't have anything to do with driving the car hard (as the dealership TRIED to allege, when my first one failed)...btw, I don't drive my car fast or hard.

Fact: If you have a Nissan CSC, it will routinely fail regardless of how you drive or service the car!
