i think it is normal i started hearing it around 1500 miles after i really beat the car up...i think it juste happens when u break the car in...

 

Yeah its normal but it is not right. I have drive other MTs and none have made this sound. Yea of course Infiniti tells us its normal. A TSB on the clutch would be a quite expensive blow.

I wonder if the rattling I hear coming from some part of my cabin is normal too. This is a great car, but could have been built more solid.

 

i get the same thing so i just always hold clutch in when i turn it off

 

The noise is caused by the dual mass flywheel and is normal. At 200-400 rpm the DMF resonates and will cause all sorts of noise in the drivetrain. Pressing the clutch in disconnects the clutch and transmission from the flywheel so there is less drivetrain to make noise.

The point of the DMF is to lower the drivetrain's resonant frequency from something like 3000 rpm down to something like 300 rpm so that you only get noise when you shut down or start up your engine, not while you're driving.

 

that sounds great in theory....but i also get the noise while driving...only in first gear from engagement to about 15-20 mph.

 

06 mt... same noise. is it me or does this manual have lots of little noises and rattles. the the tranny doesn't sound very solid, though it feels solid when you wot...
