Update on the high pitch noise

tru_Asiatik

hmmm i think everyone i right when saying you are barking up the wrong tree
from all 3 threads you have posted its seems like fontana nissan has diagnosed the problem and is waiting for an answer from HQ

with that said you have to pick up your car and wait
to be honest i hear the noise once in a while but to me it is not a problem
maybe its mechanical and thats how its supposed to sound
for example i hear the fan and hard drive humming in my computer tower does it mean its broken??


in the 370z's case if everyone hears it maybe its normal
but i dont know im just saying you might blowing this out of proportion

I have this issue also. I have the 7AT and it only happens with the engine running and when driving. When you take your foot off of the gas the noise remains until the car comes to a stop, then the noise stops. It stays off until you step on the gas. It is a constant high freq sound and not too loud, but loud enough to hear without the radio on at least to moderate sound levels. The wheels of the car have to be turning for the noise to occur though. BUT it is definitely an electronic sound, it is not mechanical. 100% sure of that.

Is it the ECM or the ECU?? Are you guys making a typo? In one of the linked threads the original guy that found the problem said it was the ECU not the ECM (I don't know what ECU OR ECM stands for, just that it is some sort of electronic component behind the glove box in the dash). Are we transposing letters here? ECU or ECM?? Let's try and get the facts straight.

So I have to pay for a car that I cannot drive and wait who knows how long before Nissan finds a fix? What if that is 6 months from now?
