To say that "all" 370's have it may have something to do with our sceptisism.

trollin-trollin-trollin...

What dealership did you work with? I'll follow up to verify.

I'd like to speak with them as well. I'm in NYC area, so it will be a cheap phone call for me. Should I speak with the Service Manager? What is his name?

:facepalm:

Fusz, where are you?!

what is "trolling" mean?

nissan tysons corner...call the service manager

Ok..i'm done posting on this thread..thanks again for everyone who tried to help me out ....this noise ticked me off. I'll post again if I have any problems in the future..email me through this if you have any other questions..
LATER

it's funny you guys mention this because when i test drove a platinum silver i recall hearing it. im a musician and have good hearing. its like you turn your head one way and the pitch just hangs there in your ear. immediately wanted to EQ that out. :D

i mentioned it to the sales guy since he rode with me and he said he couldn't hear it. he also said he's getting old and can't hear many things. i remember joking around with him that i have perfect hearing but i can't hear my wife sometimes. :D

i later changed my mind on the color and went with silver... test drove my car that i currently own and i didn't hear that pitch. i guess i got lucky.

I'd rather you post again when the bulletin gets out.

I cant hear the noise from the ECU to often BUT soon as my brother got into the car it was his first complaint. I would like it to get fixed so passengers don't complain my 35k car annoys them.

Ok just this weekend I started hearing it. I thought it was interference form the radio or just me but I can definitely hear it. And just like Kenchan says, when you tilt your head it hangs in your ear. Let's hope the dealer comes through on this.

Talked with the service manager at Hunt Nissan in Chattanooga, TN who is a good friend of mine. No bulletin as of Friday Oct. 30, knows nothing about any 370Z ECU replacement

Same with my dealership connections... There is no TSB for this yet...

Well, something interesting I've noticed. Fact has it, the G37 has this same problem, rumor has it that the EX35 has it as well. This all worked out perfectly. My sister owns a 2008 EX35 with 14,000 miles on it. I live near the city we get our Infinitis serviced at. I also own a 2009 FX35 besides my Z. I CANNOT hear the high-pitched noise in my FX. I CAN hear it lightly in my sister's EX35. It's not as loud as the 370Z, but it's there. Same pitch... Similar location. I think the Infiniti SUV's must have the ECU hidden behind more sound insulation.

I'm trying to get in touch with my customer service rep, but we are playing phone tag. This could be kind of a biggie for Nissan and Infiniti. My Z makes my ears ring. The EX was much less, but it's there. Thank God my FX doesn't have this problem. I have 12,000 miles on the FX and about the same on the Z. I am really ticked about this stupid "ringing" noise. It actually feels good to get in my FX and hear things normally. The EX, eh, so-so, but that ringing, loud or soft, shouldn't be there to begin with. What a blunder.
