Whine/Noise/High Pitch Arg!

First they said it was my speakers, so they disconnected them. Then they said it was my fuel pump, so they replaced it. Finally they listened to me and changed my ECU. All was well.

That's what I'm afraid of, that they'll change the pump, but the noise will remain. Hopefully, they're really trying to find the issue and really pinned it down, not just to shut me up. I have no idea how much more the ECU costs compared to the fuel pump.

Anyway, if it's still present after the exchange, I can go from there. Replacing the pump means they acknowledge the problem, so if it doesn't help, they'll have to look elsewhere.

Dammit, I should've waited for 6 more months and buy the 2010 model...

Just heard this noise for the first time last week. To me, it sounds like its coming from under the car, so fuel pump would make sense...

Well, I'm back from a holiday trip and I'll be picking my car up tomorrow. They've replaced the pump and now they're saying they can't hear any noises. I'm still a bit worried, because they've been handling the issue as if I was the only one who could hear it. The rep person confirmed it too initially, but later it was obvious that he's regretting acknowledging it.

Now he just says the tech people who couldn't hear it from the get go, can't hear it any longer and that it must have been the pump. Not very encouraging.

I'll let you know tomorrow how it goes!

Hi. As expected, the fuel pump replacement didn't help a bit. The noise is still there.

I didn't even take the car with me. I left it there for another try. This time, the original rep who could hear the noise wasn't available, so I made the check-in with another guy. He said he couldn't hear anything even the first time they've tried it so he cannot confirm it. So I asked him to try again, and again, he couldn't hear it, so I asked if a woman from their office could give it a try. She couldn't hear it either, but when I said it's like a ringing in your ear, she finally recognized it and confirmed that it's very unpleasant. After that, even the guy could hear it! I guess they were looking for some other kind of sound.

Nevertheless, now everybody from Nissan reps can hear the noise! I have really sensitive ears, but now that basically anybody can hear this sound, it shows how bad it is. I took my audio spectrum analyzer again and pointed out the sound is coming from under the glove box and the rep made note of everything. I even mentioned the other people on the web complaining about this and how ECU replacement fixed their issue.

I can't believe Nissan is doing NOTHING about this!

Now we wait. I really don't care if the car is stuck there for the next 14 days, because I can't drive it anyway. I won't. Getting a headache from driving a car for an hour is not normal!

Fingers crossed this will be the last attempt. Wish me luck!
