04 coupe, same prob, it goes away when ur foot is on the clutch but when it is off the clutch it is loud.. i got an appointment at the dealer monday i wonder what they are gonna say..

 

My does it too. Tried turning the car off with the clutch in and the problem was solved. I also heard this noise in my Corvette. It is normal.

 

it's normal on all 6spd. my cousins 04 porshe does the same thing but not as loud, also does the 350z.

 

I had an 03 6spd and was worried about that same noise. I just picked up an 06 a week ago and the same noise occurs. No worries anymore, its normal.

 

I dont care if it is normal. It sucks and needs to not do it. It didnt do it when I first got the car.

-06 coupe

 

i have it on my 05 with 6k miles,, my buddys 06 with less than 1k miles does too.. anoying but normal!!

 

My 05 did the same thing for a couple of days. Noticed it when I pulled in to the garage with the windows down. No mods but I thought something was loose. Waited a couple of days and now it's normal. Or at least not doing it, lol.

 

It's normal. I think it might be due to our dual mass flywheels. the autos don't make the noise.

 

It's normal. I went to a meet in Chicago last Sat. and every G35 and 350Z made that same sound when shutting down. It sucks, but it's normal...

 

It has to be the throw out bearing, with the clutch released the pressure plate is holding the clutch disk tight to the flywheel. Thus the only thing with no pressure on it is the throw out bearing. Perhaps look into a aftermarket throw out bearing if you ever upgrade your clutch/flywheel?
I also notice the sound when the window is down, sitting next to a wall or another car, echoing off of things. My maxima never made this sound, maybe I should steal that throw out bearing. XD

 

normal i get it too. being the guy i am, i tried out all the 6mt on the dealer's lot and ALL of them did this. lol

 

Ive been told that the g35 clutch is a piece of ****. My clutch vibrates when I accelerate in any gear and it rattles seldomly when I accelerate in 1st gear but no rattling while shutting down. I want an aftermarket clutch, I think thats the way to go to fix all the clutch problems.

 

It is definately the throw out bearing. I was confused by those noise for a while myself. The reason you only hear it when your clutch isnt depressed is because that is when there is no pressure on your clutch. The transmission goes through the throw out bearing and its always spinning when the car is on. Im not sure if what im saying makes sense, but im told this noise is normal.

 

i have an 06 6mt with now 1800 miles and my car does the exact same thing....a friend that i work with picked the car up 2 weeks after me and his car also does it. I dont care if every car does it, this is def NOT NORMAL at all. It's 100% the throwout bearing and there is 100% something wrong with it, im brining it in tomorow and im going to have this fixed.

 

Let me know what happens
