i'm taking my car up to infiniti tomorrow and was wondering wat u guys think this noise is. its coming from the rear

 

does it make this noise as soon as you start the car up and does the sound go away or its always there?! lol first time i heard that kind of noise on a G..yea best bet take it to the dealership

 

Sounds similar to the sound im hearing right now in my car but its more of a knocking coming from the Front of the car under the engine..If I rev the engine to 11-1200 rpms its a little louder and at idle its a hit or miss on being loud. I actually have a Appt tuesday for them to check it out. ill let u know what they say.

 

yea it makes it as soon as i start it up and stops and then starts again when i go

 

Does the noise vary with engine RPM or speed? Sounds like some sort of an exhaust rattle from the video... unless someohow one of the bolts on your fuel pump assembly is loose, in which case it could be that.

 

Looks like you need new rotors too lol. Well the noise could be the exhaust, as long as it is not constant. What i mean by constant is like when you accelerate does it get lourder and faster? Can you only hear it in the back nothing in your engine bay? Does it fo away when you are warmed up? IDK but besides it all it sounds like your exhaust hitting against something....

 

when the rpm drops u hear it and i check the engine bay didnt hear anything

 

loose bolt. Check the exhaust too.

 

the people at infiniti said it was missing or loose exhaust bolt
