Clutch master cylinder failed. I was on a highway and was unable to shift the car into a different gear. I barely made it off the highway where I was towed to the dealership. The clutch just completely lost pressure.

Premature failure of the concentric slave/master cylinder. Causes the clutch pedal to sink down and not come back up. Very dangerous when clutch randomly engages because of this. Enthusiasts have diagnosed the problem is due to plastic components used in the cylinders. There is already a aftermarket slave cylinder that fixes this problem by using metal components.

While driving the car under normal driving conditions, the clutch pedal would not come up from the floor after coming to a stop at a stop sign. After letting the car sit for approx. 90 minutes, the clutch pedal operation appeared to return to normal. I went online to research this problem and found this... per Nissan: Subject: Sb 370Z coupe and roadster; clutch pedal does not return to rest position summary of ntb13026: If you confirm: The clutch pedal on an applied vehicle does not return to its normal (rested) position after being depressed to the floor or the customer states the clutch pedal on an applied vehicle does not return to its normal (rested) position after being depressed to the floor there are no leaks in the clutch hydraulic system*. action: Change the clutch hydraulic system fluid with GT-R R35 special brake fluid (see parts information). - refer to service procedure for bleeding procedure. See this bulletin for further detail. I took the car to a local Nissan dealership and they were able to replicate the problem. Their solution was to replace the clutch fluid withe the gtr R35 special brake fluid as described in the service bulletin. However, I've read multiple reports that this "fix" only holds up temporarily and, that eventually the csc (concentric slave cylinder) and/or the cmc (clutch master cylinder) fail. Many, many 370Z owners have had to have both the csc & cmc replaced. The Nissan dealership where I took my car said they would replace those parts but, only if I experience the clutch pedal failure again. My feeling is that they should've replaced these parts when they replaced the fluid since they're aware that merely changing the fluid is not really fixing the problem since the csc & cmc so often fail even after the fluids have been changed.

There is a recurring issues with this vehicle where if driving long distances suddenly the clutch would go to the floor and eventually lose all resistance and make the car undrivable. I discovered this shortly after I purchased the vehicle at 20000 miles. I took it back to the place I purchased from and because it was intermittent they could not reproduce the issue. The next time it happened I was told to take it to the dealer. The problem came back and I was told I needed to make an appointment at the dealer. By the time I took it to the dealer it was again not happening so they were not able to find the problem. Saturday the 18th of Jan. It happened again and I was able to take it to the dealer while it was happening. They found the problem was the slave cylinder leaking but because now I am over the warranty Nissan will not cover the issue. I have researched this issue and seen several people complaining about the intermittent issue with the clutch that goes to the floor with very low miles on the car. The issue seems to be that the part that breaks is plastic and Nissan hasn't redesigned it since the 350Z models that also experience the same issue. Please can someone look into this?
