Go to the nissan dealer. It's under warranty.

yes i heard that sounds when i drove windows up 1st and 2nd gear over 2500rpm. but the sounds were gone when i drove 20~30min later.
so it's strange thing

okay i'll try when my car have noise

yesyes the sound is coming when it is only cold . so i checked up today morning. but the sounds didn't hear today...so it's sometimes came, sometime didn't come.. so dealer and me couldn't find where is sounds coming from..

It appears the Sounds in the recording makes it the sound worst due to an enclosed area making the sound frequently bounces of the walls amplifying that weired normal engine sound of the VQ engine.

Honestly our engine sounds like a washing machine when cold and when inside a garage. But if your out in the open and it warms up you dont hear it. the normal sound of the engine is like crap. You'll get used to it. Besides it new all the engine components are still tight and it will get better when you reach the break in miles.

Once you get to 5k or 7k switch your oil to an ester based nissan oil or redline.
Ps dont make this thread another oil thread discussion.

Use the search feature and read about oil discussion.


Then again for peace of mind bring it yo the dealer but I'm 100% sure they will say nothing is wrong with it because in the first place they dont know much about sh** on our engine.

That definitely sounds odd to me ... I would have the dealer look at it. If they say it's normal, make them start up a similar age/model Z and see if it's making the same noise. There is a squeal in there that doesn't sound right - first guess I'd think it was a belt, but I generally wouldn't expect that with a brand new vehicle.

OP keep in mind that if it is a clutch noise, that our clutches are loud to begin with. I had the same question when I first got mine. I took it to 2 different dealers and they state that it's a characteristic of the Z. I couldn't really make out the sound you're questioning, I'm just adding my 2 cents in, in hopes that it helps a bit.
