I'm sure that the overwhelming majority of '09/10 Z's have NOT experienced the problem and many of the ones who have have gotten it taken care of, under warranty, with an ECU change. It sounds more frequent than it actually is because so many of those who are troubled by it find the Forum to report it there and seek information there regarding the fix. My car does not have the problem.

Seriously man?!?! I would say his hardship is valid. The trouble of bringing in the NEW car to the dealer nonstop over the past few months is a royal pain to begin with. Then battling with Nissan regarding fixing the problem and taking ownership of the issue, to the point of having to hire a lawyer.

Geez cut the guy some slack. It's clear Nissan has a QC issue with the Z. The car isn't supposed to make a pitchy noise when you drive.

I agree he should be compensated for his time and effort.

Mine has replaced ecu and highpitch noise is gone.

I think I'm the only one, has been fixed this noise

I keep telling my dealership it's the ECU, but they are insisting on trying everything else. Lol.

Good deal! From what I've been reading on the G37 board, only the '09s are effected. '10s do not have this problem.

Okay, I got my car back from the dealership, They figured out it was the ECU, confirmed it and is ordering a new ECU for me. I should have it in 2-3 weeks.

WISH ME LUCk!

you have to make sure they ordered correct part. The ECU serial number should be ending with A.

ARE YOU SERIOUS??

There are so many things wrong with your post i don't know where to start...

that made me laugh..haha

Thanks dude, They just told me the serial is different from my stock one he didnt' let me know what it was though.

I have this issue on my car..but to be honest right now I don't really care to bring it to my dealership to get fixed. TBH I don't trust them at all to do anything with my car. Maybe a TSB will come out to fix this? It doesn't bother me too much..Probably try to get it fixed down the road.

im at the dealership to get my window fixed on the driver's side, the window automatically rolls up when the door is closed but does not seal off to the rubber all the way, therefore creating a loud high pitched wind noise while driving at high speeds, blahhh

anyway, i also mentioned about this high frequency noise (Which i have as well 2010 model) to the service rep. and he got inside the car with me and after listening to it for awhile said he cannot hear anything and looked at me like i was crazy....

Anyway, looks like the g37s were able to find a fix.. why not the 370z??? or is there a fix for this yet? did anyone ever contact consumer affairs yet?

i just want to get everything fixed, its irritating to have so much issues with a brand new car.

So... Service Rep. finally said that his tech hears the high pitched noise as well and is calling nissan hotline for instructions.

He said they are looking at "other alternatives" to quiet the noise and see what the noise level is because the ECU replacement will cost nissan 1300.00??? is that true? why not just replace the god damn thing because its a manufactuer's defect? Are they allowed the reject what i want with my own car as a customer, just so they can save 1300??

Ive been waiting 7:30am in the morning and im still at the dealership and its 2:25pm. FML

If they acknowledge the fault then dont let them do a bandaid, have them fix it by replacing it. I dont think warranty work costs the dealership anything does it?
