High-Pitched Frequency Update

semtex

I have never heard this noise in my Z, and thank goodness for that, because that is one ANNOYING sound!!!! I have newfound sympathy for those of you who have this going on in your Zs.

Any high-frequency hearing loss, Semtex?

Not that I'm aware of. My wife swears I have hearing loss, but she doesn't realize I'm just ignoring her.

The sound is bad enough, but two things really make it worse. One, it comes and goes depending on how you turn your head. Look at your left side mirror and you hear it, turn your head enough to the right and you hear it. That almost makes it worse than a constant noise. (ALMOST). the other bad thing is it lingers in your hearing after you get out of the car. For the next 30 minutes to an hour you still feel like you are hearing that high pitched noise.

I have been putting off taking my car in hoping that a TSB was soon to be released. That would mean I wouldn't have to go in and argue with the dummies at my dealership that there is a noise coming from the ECU. However, I am not sure how much longer I can stand this stupid noise. I like AM radio in the mornings and at lunch, but usually listen to music in the afternoons which will cover the noise.

I have taken mine in. You want a name and dealer? I think John, the older service manager couldn't hear it. Sean, the younger manager, got in and heard it right away and called it "annoying." This is Russ Darrow Nissan in Milwaukee. There are your names.

They reported it to corporate, I called the Consumer Affairs line and talked to Lisa, my MW CA rep. She went over to the Infiniti office and they confirmed this was a problem. Lisa told me that they are working on a permanent fix. She didn't know about a TSB issued, nor one coming. Just, "We are working on a fix and you are not the only one with this problem."

Russ Darrow Nissan, who has been very, very nice, is watching their TSB list every day, watching for the ringing TSB. They said they would call me THE DAY it came out.

They offered to replace my ECU if I'd like, but we decided to just wait until there's concrete evidence of a fix.

For now, I will wait. LSUTurboTiger has the description right on, and Jungle and the G37 crew has the pitch, 10kHz, down to perfection. Those of you who can't hear it, you are lucky. Your ears ring for well over an hour after you get out of the car.

For those of you who don't know, this is a problem not only on the 370Z and the G37, but I also heard it in my sister's 2008 EX35. This is affecting most Infiniti's with the 3.5/3.7, and of course, our 370Z. I haven't checked if the Max, Altima, or Murano are having it. Honestly, I have not been able to hear it in my 2009 FX35 yet though, though some on the FX forum have been hearing it as well. I don't think the FXers know how big of a problem this is for a lot of Nissan and Infiniti owners. I think I've done all I can for now. If Lisa told me they're working on a fix, I believe her. Why would they just say that? They said they were working on a Nissan Motorsports Oil Cooler before it came out, and they did it. I don't see them 'lying' about this.

The point of this... The fix can't come out soon enough.

WooZ

So Nissan knows of this problem even from the 3.5 and there is still no fix since then yet? That's weak.

TheWeatherman

Yeah. The EXers are well aware of it.

probably because nobody has really complained about it before the way the G/Z crowd is right now. i commend the G people for isolating the sound. that's the exact frequency i'm hearing, and even now it just frustrates the hell out of me. the noise for me basically occurs after the car is warmed, no matter what gear i'm in, and no matter what i'm doing.

and i thought i was crazy when i first got the car and had ringing in my ears when i stepped out of it!

Weatherman: clearly your dealership is much more helpful than mine, who are completely clueless.

You should take it in and at least report you have the problem. At the very least Nissan can get some statistics back from actual customers.
