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

tru_Asiatik

i dont really see it as a problem(it became a problem when someone made it a problem) i know i have the noise but over time i dont hear it anymore especilally when the music is on or windows r down, even that all i hear is the exhaust
the high pitch noise....is NOT that Loud(mines and other 370z ive been in

as far as i know i have not heard anything if the noise would cause a problem on how the car performs

just to put thing into perspective...some people mind the noise some dont...so its up to the person that means it is up to you to decide if a little noise would affect your decisions
I(or should we say we) would not try to convince you on a decision..its your call
you seem to contradict everyone that is saying get the car so if you dont want to get it...dont get it

im sure the next car you look at would have a problem YOU wouldnt like... :P

"It became a problem when someone made it a problem"

That doesn't make sense. The sound is there on alot of cars, it bothers alot of the drivers as you can read in the first link i posted so it's indeed as im learning from this website, it's a prob. Just because the noise does not effect you, does that instantly make it "not an issue" Thats an interesting way to look at things in life "if it doesn't effect me then its not a problem"

I know what you are getting at, don't worry bout the small things etc but your car doesn't make the noise loudly at the moment and thats awesome for you, i'm happy for you and you are lucky you didn't get one of the other cars that are alot louder/ hard to ignore. Some guys on here are saying its so bad it makes their ears ring for hours afterwards.....sounds pretty ridiculous for a car to do that to its owner doesnt it.

So far in this thread 7 people have the ringing sound in their car, 5 do not...one guy even said its so bad he is not sure he would have bought the car if he knew about it prior......sounds pretty bad

I'm not askin you to convince me to buy the car like you are saying, i'm here to find out how bad this issue really is on the 370z. Thats why i made an account her before purchasing the car, see i was all set to buy it then started reading the threads regarding the noise, turned me off the car instantly which is a shame because in every respect it seems great.

I have driven it for a few days, the dealer lent a 2009 model to me, not a long enough timeline to see the problem. On that particular car i could hear a noise, even with the radio on....pretty crappy but nothing really to worry about BUT i have read on this very site that it gets worse/louder. If that happened i would not want to drive it, would annoy the hell out of me and my girlfriend/people riding with me and felt $70k wasted

So the reason i am here is not for you to convince me to buy the car, but rather, like i said in my first post, to find out if the 2010 models are clear of this problem and find out how it effects you guys with the 2009 too

They said they found the ECU which has serial number end with B, makes high pitch noise. Old ECU should be change to New one which has serial number end with A. My service maneger checked ECU's serial number on my car and it's end with B. That's why my car still make noise even though they changed to new ECU. My stupid service maneger didn't check it before he placed order.

Anyways...I hope it's true this time.
Dealer just gave me a rent car(sentra) and I have to wait another 1weeks to get it fixed. I will update if its fixed."

The discussion about the ECU ending with B and ECU ending with A was never resolved. I would love to know if the ECU A does fix it up 100% and have pmd bumblez.

Thanks to everyone who responded in this thread and the australian thread as well. The couple of guys with 2010 were kind enough to reply, both said no noise yet which is a really good sign for everyone

From here if more 2010 owners report no problems then we could safely assume Nissan has fixed it and we will all be extremely happy...and i will buy this bad boy in black with

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.

Cool, thanks Ubunoir

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.

**** man...i really hoped it would have been fixed for you!!

At least its been reduced a lil bit, how loud is it now? can you still hear it even if you have the aircon on/ or radio on??

From here i would get the general manager in your car to hear it and really if they can't fix it demand they replace the car, you didn't pay your hard earned money for a car that makes abnormal noises and ruins your driving experience.

I actually just test drove a black 370z auto 30 mins ago and this time made a point of listening out for this sound you guys are talkin about. Basically i drove the car as i normally would and could not hear any noise. Then i went through 1 by 1 turning things off to see when i could actually hear it.

Whilst driving - windows up
1. Had the radio on and aircon on - couldn't hear it
2. Turned the radio off, aircon on - still couldn't hear it
3. Turned the aircon off, basically everything off, windows up and i could hear a very faint sound, my girlfriend could hear it too

She said as soon as i turned the aircon back on, on the lowest setting, the sound vanished. I then turned the radio on too and of course she couldnt hear it at all. This car had 20kms on it and was brand new but it was a late 2009 model bordering on 2010, so i really wonder if the sound would get louder/worse or effect earlier models more??

I am going to test drive the car again next week but for a few days this time to see how it goes, i totally forgot to lift the hood and listen for it so i will do that too. Going to get my brothers and friends ( all around 20 years old ) to listen out for it, see on a scale of 1 - 10 what they would rate the sound at.

It's possible that all the cars have some very low sound that is not noticable but just over half of the cars are effected by this being louder than the rest being the ECU and or wiring (based on what people on this website and friends who own have told me)

The dealer i went to today was really the nicest car dealer i have ever met, he was above and beyond normal experience. I told him about this website and the only thing stopping me purchasing this car is the potential ECU sound issue. He guaranteed if it happened he would fix it no matter what it took, i'm sure he would even give me that in writing too, which i would need before i bought the car, i will let you know how i go.

Thanks for reading my long *** post! And i really hope you guys with the issue louder than normal, i really hope it gets resolved for you so you can enjoy the car

Peace

As you know, every people has different hearing level. For me, that high pitch noise too loude. Even though I turn on the radio and air conditioner, still can hear that noise clearly. It has been reduced since they put new part yesterday. However, I could hear that and I don't want to drive this car anymore. Some people think that noise is not an issue but as you said, I didn't pay over 30K to have a car that makes noise and not repairable. Last week, I test drove an another car in the dealer which is same spec but has sports package on it. I could not hear the noise from that car. If I have chance to replace to another one, I hope I can change to that one I tested dive.
