Clutch Bell Housing problems of the 2012 Nissan 370Z

Concentric slave cylinder leaked all of the clutch fluid while parked overnight. Clutch pedal went to the floor when we tried to start the car in the morning. While looking for cause of problen, I found hundreds of similar complaints on line for very similar problem, going back as far as at least 2009 and up to the cunnrent model year. To make matters worse, Nissan wont cover it under their power train warranty, saying it is a clutch issue. It is located inside the transmission bell housing. My warranty book does not exclude this item, Nissan customer care calls it part of the clutch item and claims its not covered. So repair has been denied by dealership and Nissan customer care. I have a case number if you would like it. The consensus is that this cylinder is failing and not robust because it is made of plastic, and is losing its round shape when hot, therefore causing the seal to fail and the clutch fluid to drain. By bill to repair locally was 1012, which included dropping the transmission and installing a robust (metal) aftermarket csc. This Nissan csc is a documented failing part and I feel it should be subject to a recall for replacement, with owners who have already paid to have the issue fixed being reimbursed for their expenses. I talked to jennifer at Nissan customer care, and my case number was 25999561.
