This is driving me nuts so I gotta ask on the both sides.

I just picked up my 2009 G37 Sedan Journey, Premium, Navigation, and the Sports Wheel package from the dealer last night.

I hear soft, High pitch/frequency noise coming from inside of the car when the Engine is running, and the car is moving. I think the noise seems to stop once the engine RPM goes idle, but once the RPM picks back up, the noise comes back. It seems to come from the Front Passenger side.

I disconnected iPod, iPhone, and audio off and it’s still there.


Anyone know how to fix this before this noise drives me nuts?


Thank you for you help!

 

get betty's grounding kit, might fix the problem. ask betty.

 

Omg... Am I the only one with this problem?

or is this common problem with this car?

 

I honestly have never heard of this problem bro... Might wanna call service and ask them what the hells up... Hopefully they can shed some light on it...

So... No sedan people with the problem?

 

Nope, not me. You should take it back to the dealer and see if they can diagnos the problem. You've only had the car for a day so it will be covered under warranty. Just curious, did you notice the noise during your test drive?

 

No. funny thing is when I was test driving, the music was playing to show off the audio system.

 

This might help.

Not sure if this is what yall are talking about.

 

No, this isn't the sound.

It sounds like the beep/high frequency noise you hear during the hearing test.

 

just take it in and show them... hopefully you can reproduce it while you're with a tech... if it's really that annoying...

 

My grounding kit will definitely NOT help the problem. I have the sound too. I had the noise before I installed a grounding kit and I still have it afterward. Mine is very specific: I only hear it when I'm pressing the accelerator and only from about 77 to about 82 MPH (or at least that's he only time I really hear it). It's an extremely high frequency whining/ringing as you described, like one of the highest test tones in a hearing exam. It's annoying as fuck and I try not to think about it because I know Infiniti will 1) say they can't duplicate or hear it 2) not know what's causing it if they do admit to hearing it 3) do absolutely nothing about it. If anybody has any luck isolating it or finding a fix. please post it.

But if you do buy one of my grounding kits, your car will gain 45 HP, 32 TQ, and get 7 MPG better mileage.

 

Really? That's it?? Weak!! I'm gonna have to go with White Wanda's Grounding Kit instead. It'll run circles around your puny gains.

hehe jk of course. If I had an AT, your kit would've been the first thing I bought.
