My clutch pedal makes the same noise when I release it from time to time. Haven't seen any effects on performance. If Nissan hasn't said anything about it I wonder what difference there will be with a replacement pedal.

I happened to be at the dealer today for an interior panel issue and spoke to the service manager. While scheduling an appointment with him I brought up the clutch problem. I haven't had time to go back and have this further troubleshot. The service manager indicated they had been working on another Z with he same knocking issue. The entire pedal assembly was replaced along with some shim modifications. The problem never has been resolved. I suggested it might be a hydraulic issue but he felt it was still related to the pedal. It seems there is too much play where the pin meets the pivot assembly. I will update everyone once they look at my car.

brought my car in this morning for the replacement clutch pedal and got it back around noon. the new clutch pedal feels good. no more clicking noise at the top of clutch release. just wanted to update this post. oh yea, i took at mission hills nissan.

Thanks for the update Ryann. I hope they can resolve my problem too. The noise and feel of the clutch drives me crazy when it happens.

Ur welcome. I'll update if the problem comes back with the new pedal.
