Yup, I get that high pitched whine right after I shut the car down as well. It lasts for a few seconds, then goes away. It doesn't seem to have any effect on the car that I can notice, but I am curious as to what it is.

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

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

Could be the door lock actuator.
