Are these issues not just NTSBs.?
Don't recollect recalls on these issues.
I had one last week where the concentric slave had failed and the clutch got contaminated with fluid. I fought my customers corner and we got 100% labour, a concentric slave, clutch plate and clutch cover all under warranty.
The car was a 350Z, 2007, 29,000 miles, Full Nissan Service History.
