Question - Does your car make the high-pitched ringing sound near the glove box?

Ubunoir · 01-13-2010, 02:35 PM

Just to be clear, the noise I hear is definitely coming from the throttle body area under the hood, not the passenger footwell. From inside the cabin, you could mistake it as coming from the footwell, but it's not.

As I mentioned, it doesn't bother me but it bothers my wife. It's not the volume because it's really not very loud. It gets drowned out by the radio, tire noise, or wind noise if the window are down. It's also not super-high pitched. It's about the same frequency as the emergency broadcast signal tone, if you know what that sounds like. It's not like a dog whistle or something only teens can hear. I think it's just the constant tone that bugs my wife. I didn't even notice it until she pointed it out. Of course now I can't 'Un-hear' it.

For comparison, If my miata made this noise, it would be impossible to hear at all. The general cabin noise level is probably 2x that of the Z.

Ok... here is update for my highpitch noise.
My dealer just change ECU which is ending with A..
That noise has been reduced a little bit but still can hear.
General service maneger was not there when I picked up my car.
I think he might say try another ECU.
Anyways... we gonna talk about this on monday.
I will ask them to change to another Z.
If they say NO?? I will hire an attorney.

Hey guys does the car have an inverter or ballast / transformer of some sort? That kind of sound is very common to inverters...

dudafunk · 04-13-2010, 08:21 AM

fullmonty, i have that too (i have the high pitched noise AS WELL AS this other buzz like two live wires are touching each other regularly emitting a spark - i couldn't find a thread on the forum that described this other one). Have had both issues since bought the car at 7 miles.

Im also in the market for a Z soon! Is this problem only limited to 09's or also 2010's?

Just the '09s. Same with the Infiniti Gs. No issues with 2010 models.

The fix for the Infinitis has been an ECU replacement. Sucks that Nissan is dragging their butt for you Z guys.

Tyrell Tyson · 04-13-2010, 10:13 AM

Bleh the recent poll shows us that even some guys with 2010s have the ringing noise, it would drive me insane

I think i have decided i am going to buy a Cayman S at this point

POLL: High-Pitched Noise: You Have It?

That is the link to the recent Poll for anyone that missed it

To sum up quickly

370Z NOISES: You Have Them?

YES: 2009 Coupe ECU = 29

YES: 2010 Coupe ECU = 4

NO: 2009 Coupe ECU = 19

NO: 2010 Coupe ECU = 6

Wow its over HALF of all owners have the sound, that is CRAZY

370Zsteve · 04-13-2010, 10:39 AM

ty, the sound you hear is just the normal noise in your head

Prawnfret · 04-13-2010, 12:05 PM

it's like the sound you get stuck in ur ear after a night out at a club with too loud music or sometimes when you're in an extremely quiet room.. except in both instances it goes away and in the Z it doesnt as long as you're driving. how would an ECU emit such a sound? i get the funny impression that something is vibrating at its harmonic resonance...

Soon · 04-13-2010, 04:43 PM

hybridnation · 04-13-2010, 06:33 PM

Csquared · 04-13-2010, 09:00 PM

Swaped out my ECU, noise is gone. They wouldn't give me any info on the ecu they changed, just that it was a brand new 2010 one.
