When are you going? I just stumbled upon this thread and have to say I haven't noticed the sound at all in my '09 G37 Sedan Premium with 8,100 miles.

I hope I don't, but glad you guys ran down a solution!

Let us know how it comes out. I too am very sentitive about rattles and noises and this would drive me nuts as well. My hearing isn't the best (old rock and roll fan here) but I could likely hear what you all are describing.

You probably lost that frequency sometime between a jaeger shot and standing too close to a (band of choice) concert mid stack, lol.

I believe I saw this question posed, but don't recall seeing a response --- is the high-pitch frequency noise a problem on the 2010 Sedans as well or are those already coming off the line with the fix in place?

i dont think there are enough 2010 owners to confirm if they have the noise. also most people dont recognise thge noise until a few thousand miles.

TinsleyC

Yup.. somwhere between my first concert, Led Zeppelin in 1973 and the loudest I can recall, AC/DC in 1991. The Stones at the Cotton Bowl was great too!

my car is getting a new ECU as we speak....
we'll see if that fixes the problem, because so far both my loaners had the issue.

beerme, any updates on your noise, was it gone?

I was told to bring my car in this morning to a philly dealer to have the ECM replaced. I have been there complaining for 4 months now. They called me 2 hours later to tell me the part is on national backorder. They are the biggest lying bunch of a--holes. I will never buy a Nissan product again.

yea I posted before that I had the fix applied with details. no noise so far!

and as for the part being on back order, i would say false as this fix has JUST been released.

i cant stress enough, CONSUMER AFFAIRS if your dealer is being a pain.

Maybe it's my ears.. but i never heard this in any '37 loaner nor in my '09... glad to know there's a fix in case the issue should come up..

I wouldn't get too upset if it's on back order. Consider they just released a fix (upgraded ECU) and they are likely short on inventory of the modified ECU. After proving they have a fix, I bet it's going to take a couple of months to create enough inventory of modified ECUs. They might need to recycle and modify older ones into other cars so the whole process could take awhile.

i know it's hard but try to hang in there.

just got my car back, ecu was replaced, keys reprogrammed and now the noise is GONE!
i love it.
fwiw, please contact consumer affairs.

I'm going to my dealer in Mobile, AL - Bullard - My noise was confirmed and discussed at length (that is, what to do about it) with them sometime back - I need to get my 7500 mile service performed, and oil change and I'll have them do this as well.

Picked up my car this morning with the new ECM in place. No noise so far! I will keep you guys posted after a couple thousand miles.

Same here. Picked it up this morning and no noise! Hallelujah. My work order says "engine control module - 23710-1ND9C.

FYI, the intelligent keys need to be reprogrammed when the ECM is replaced, so make sure to bring all of your keys in to the dealer.
