Screeching Noise at high RPM ?
Hey guys. I have a CPO 13 G37x Sedan. Lately I've noticed that when I floor it. It takes off. Then when I get into the higher RPMS it makes a screeching noise. I've searched the forums and have my been able to find a for sure answer. I am still under warranty. I hate hearing this noise every time I want to hit the gas hard and take off a little bit. Anyone have any experience with this or if anyone can offer a solution it would be much appreciated!

It's not the infamous VQ hiss is it? I get a small hissing noise at high RPM's (from what I've read this is common in VQ engines). It sounds almost like the car is taking a breath. I wouldn't describe it as screeching though.

Sorry to revive such an old thread.....
I have the same screech and had done some searching a couple months ago, found this thread, and at least 1-2 others. The consensus is that it is "normal", but no cause was found.
Fast forward to today, and saw this clip in an exhaust thread.... guess what I heard in the video when the RPMs got high? Yup, the same screech. (Almost sounds like a hiss in the video, but in the car it sounds like a screech).
Basically just adding this here so others can hear the noise when viewing this thread in hopes that a cause will be found eventually.

Yes, my car does the same - Especially between 130mph to 140mph
At first I thought one of my windows was down but nope - This is how it is.
It's like a whistle sound that it makes - Can't watch your video - @ work but I think I know what you're on about
