Noise when Shutting off the car?? ANYONE?

bluntman5551 · 04-16-2010, 03:15 AM

I got a used 09 370Z with 7K on it. I have the clunky sound in first and other "normal" things people experiencing with their 370Zs. My question is, Does anyone have an abnormal noise when shutting off the car??? Basically when i shut it off, when power gets cut from the engine it shuts off normally but at the very very end it goes "clunk, clunk". It sounds like its coming from the engine, not engine bay... But im really hoping that its something loose in the engine bay. Anyone??

didn't notice anything like that. the only noise is this ticking noise coming from the engine/exhaust since its cooling down.

Its normal no worries. at idle push your clutch in and out and youll hear what im talking about. this tranny just makes a lot of noise.

Yea man I noticed just today when you let off the clutch in neutral it makes rattling sound and was gonna ask if that is normal..... Im more than willing to live with all the noises. This is my first nissan and i f***ing LOVE it! It SOOOO FAST, especially in 3rd and 4th. It gets upto 130 in NO TIME. I gotta slow down , I was doing 110 on the street the other day. Going 80 on the street doesnt even feel fast anymore haha.

Thanks for the answer, I was worring it was something big.

Mine makes a lot of high pitch whining after the car is shut off, I figure it's something with the fuel injection system or something.

Does it for about 1-2sec.

Thats the throttle body alignment. it will do it everytime you shut the car off. many newer cars do the same.

kannibul, my car does what yours does. it almost sounds like it's beeping, then it dies out after 2 seconds.

Yeah, I'm not worried about it, it's done it since day 1.

I just let out the clutch when i'm in gear to turn off the car and it makes a clunking sound every time...

When I push the button to turn off my car.. if I pay attention, it sorta sounds like a jet is powering down. I actually love that. LOL!!

dthem370 · 04-16-2010, 10:11 AM

Mine only does it after I've ran the A/C. But it does sound wicked.

If only it did it when you cranked it as well haha nothing sicker than a Z powering up like a jet engine lol.

My G37 does the same noise once in a while.

vipor · 04-16-2010, 11:12 AM

Might be the ol' throwout bearing rattling. Turn it off with the clutch depressed, see if it still does it.

Ive just learned to turn my car off with my foot on the cluth still. Never hear that clunking noise. Vipor I believe you're the one that actually gave me that advice a couple months back! Works like a charm!
