High-Pitched Frequency Update

TamZ

I hope that happens with mine. I just noticed mine starting to get it..8000 miles. I really don't want to have to deal with getting it fixed. If i turn the radio up (which it usually is) I don't notice it but if I have the radio down, and I'm sitting (not driving) its noticeable. Frustrating!!!

I'm old. Maybe mine will go away too.

Sorry to revive an old thread but this was the most recent one I could find when I searched.

I am sad....

My Car now has the annoying high frequency noise. I hear it whenever the car is moving..as I come a stop, you hear it stop..when I go, just nearing 1000rpm..off it starts again... It's especially aggravating when I turn to look out my drivers window and my right ear faces the passenger side front/glove box area. It's becomes even louder.

I have only driven the car a few times in town since my Vegas trip (the high frequency noise started long before my oil temp vegas trip issue). It's going in to have the oil changed, the rear hatch issue fixed (hopefully) and I'm going to try and get them to listen to this high frequency noise. I know some people say its not that bad. But for me, it is. And now..its all I seem to hear, now that it's happening. I have 9300 miles on the car...seems like it started around 8000 mile-ish. I was SO crossing my fingers that I wouldn't get this noise. Sucks

I went to the Mercedes dealer because my H2 keeps having issues and is on it's last leg. Drove a GL450. Only problem is, my husband may say I have to get rid of the Z. It's a tough call, I'm becoming so frustrated with my little issues on this car. I LOVE MY CAR But...

wish i could say it goes away with time/mileage but i have 41k on mine now and its still there.

Sigh...

If they FIX it, I'll be fine. I'm just SO not looking forward with fighting with them to get them to replace whatever an ECU is (which seems to be what I've read when I searched the problem on here.) I don't have TIME to be back and forth to the dealer, I'm in nursing school! Ugh.... In my dream world, they sit in the car, hear it immediately and say, "we'll fix it right away" and all will be well with the world.

Ya right.

the trick is to get them to sit in the car and agree theres an abnormal sound there that needs fixing. I had this old guy sit in my car the first time and needless to say all i got was some skeptical looks. then i went to another branch and had this younger guy listen. without revealing too much info at first i asked him whether he heard anything and where he thought it was coming from. and viola he actully identified the sound and the area it was coming from.. then i promptly whipped out the stack of printouots relating to this problem from this forum (and there is alot). haha i think he had not much choice but to concur with me from that point!

well then they did some mandatory sound tests (they still didnt believe it was the ecu intiially) and eventually replaced my ECU with that from a newer Z.

and the sound is absolutely and completely gone!

after my complaint he went around testing the other Zs and apparently the vast majority of 09 370zs have this problem, some louder, some softer. GTRs have it as well

all the best in getting ur problem sorted out. i know i felt immense relief when i had mine fixed.

TamZ

I'm glad you got yours fixed. I seemed to have solved my problem with my high frequency sound:

I sold it. LOL!

I've missed her every day but am enjoying my new MBZ GL. I do sort of feel bad that whoever buys my used 370Z at the dealership will have to deal with that high frequency noise.

I was JUST getting ready to take her in to have this looked at when my H2 broke down and we decided to just get the new GL. Even my husband could hear the sound, so I was hopeful that someone at the dealership would be able to as well.

I actually brought my car in today to get it fixed for this problem and they claim they fixed it by reprogramming the ECU. Not sure if it works but I'll let you guys know. So if you have the COBB may be possible to reset the ECU and solve the problem?

Paskii

Got back from the dealership, doesn't work they said they will need to investigate more and probably need to replace it which is what I prefer anyways.

Incredible that some dealers are still clueless on this issue

Went to the dealership last week, and the service guy handling it said there was a fix and he ordered me a new ecu straight up without asking to listen to it. It was a first after many attemtps to get someone to fix it. I asked bumblez, another user on this forum cause he said he had gotten it fixed at a dealership in richmond, va and i called up the guy. Was going to use him as a reference at my dealership but like I said he just ordered a new part straight up. I am so relieved now !

Anybody in the D/FW area found a dealership that will fix this problem? I haven't taken my 370Z in just yet (it does have the high frequency issue), but I called Nissan of Fort Worth and the service manager was absolutely clueless about this.
