Two problems related to power train have been reported for the 2013 Nissan 370Z. The most recently reported issues are listed below.
The clutch slave cylinder failed which results in not being able to put the car in gear once you have stopped and placed the car in neutral. This failure happened at an intersection and caused me to not be able to proceed. One car almost slammed into me. Nissan has known about this inferior plastic part since 2009 and has not changed anything.
Had no pressure in clutch about a year ago while driving on the highway and kept getting stuck after releasing it. Had the clutch and flywheel replaced, problem went away for a while. But it's been less than a year, and I am having the same problem again. I was driving on the freeway in stop and go traffic, and the clutch suddenly had no pressure halfway again. Now the problem might be the clutch master cylinder or clutch slave cylinder. It happened suddenly on the freeway with no indication of warning. I still have stock power terrain parts. I have seen many people on 370z forum with the same exact problem.
