High-Pitched Frequency Update

Silver37 · 12-02-2009, 06:59 PM

The noise seems to come and go in my G37....either very loud, or not there at all. I'm trying to sort out what might be triggering it as an interim fix until Infiniti/Nissan sorts it out.

I took the 370Z today to the Service Manager over at Curry Nissan (NY). He heard the noise and was trying to figure out how to handle this. He didn't want to begin cutting up the car. He said he'll bring this up to his Region Rep next week. But he did ear it! They weren't sure what devices are near the passenger side to cause that noise, other then the ECU which he didn't think would make a noise like that.

So I just hope Nissan is actually working on this issue, because I think I'm loosing my hearing lol

That's good news that they are trying to sort it out. My service manager said to bring it in when it acts up again and they'll try to isolate the problem. So far, the in the two times I've taken it in, the noise hasn't been acting up those days.

Silver37, did you take the Service Manager out for a drive? I took mine out on the highway and you can def hear it. Then when I took him back to the shop we were in the parking lot trying to isolate where the sound is coming from. Whenever I rev'd the car you heard it and as soon as i let go of the gas the sound stopped.

Finally... My service maneger decided to replace ECU.

getmecoffee · 12-05-2009, 01:05 AM

Did that fix the noise?

Silver37 · 12-05-2009, 11:11 PM

Yeah....that would be the first actual fix that I've heard of on this topic!

I just got called from my service maneger 2days ago. He said he just placed order and the new ECU will be there next week. I'll post my result after they replaced it.

But he said he is not sure this noise will fixed.

BTW, I figured this was worth mentioning, but I remember getting off the track the first time and popping the hood, and holy **** that whine was surprisingly loud. I heard it with the hood down, and when I popped it, it was even worse.

It was the first time I'd ever heard it.

same as mine. I can hear that noise, standing outside of car. That whine is F****** loud.

MightyBobo · 12-06-2009, 01:14 AM

Kinda worried me because this happened on the 1st day, and on the 2nd day I didnt hear anything at all, and that was when my TCS/Low traction lights were light up solid.

So the other night it was unusually warm and I was cleaning the car.When I was finished I was having a beer and smoking one of my buds from my new crop and it suddenly came to me!
The sound you are hearing is an old Led Zeppelin tune.It is very hard to hear it with the human ear but after the bud I smoked it was very clear to me that is what it is!I actually like it guys!
I'am not taking mine in if there is a recall!

umm what

cool story bro

So, I think my wife heard this noise for the first time. Can it only be heard from the passenger seat? She said she heard something, but only with her head turned in a particular direction. From the driver's seat, I couldn't hear anything. And, she only heard it when I had the radio off - are these the normal symptons?

From following this both here, and in the G37 forums, the answer is yes...... to the "inside the car high pitched whine" issue. The "under the hood" high pitched whine, that has been attributed to the electronic throttle, is a different animal then the inside one everyone believes is the ECU.
