I hope I'm right.

That's correct- the job goes by the mileage at the time the claim was created, not the mileage of the car at any other point during or after the claim.

Just to let everyone know, I had a one-on-one drive-around with the head tech at my local Nissan dealership. We drove around for about 30 minutes. At first, he couldn't hear it, but the more I pressed and explained, the more he seemed to understand what the heck I was talking about.

It also seemed to really helpful to have the tech slowly shake his head back and forth. I think the frequency is so high that it almost becomes directional, so as your ear gets a more direct line toward the noise, it sounds louder or more prevalent. Whatever the reason, after he did this (and we both looked like complete idiots) he really keyed in on the noise.

All that being said, he was unsure of the exact problem and said that he would give the Nissan tech line a call.

I left and about an hour later I received a call from the dealership. They said that Nissan was aware of this issue with the 2009's, but they never entirely nailed down the cause, which is why they didn't issue an official TSB. Regardless, my dealership ordered a new ECM unit and are going to install it in about a week. Best part: either Nissan or my dealership are going to "goodwill" the problem and are going to fix it under my basic warranty even though it expired about 3 weeks ago.

I wouldn't rely on my situation and let your warranty lapse before you get the issue fixed, but all hope is not lost if your warranty is expired. Might as well try and see what happens.

Hope this helps.

Great to hear. It's definitely a noise that changes based on which direction your head is turned. Let us know how it turns out.

maniacdave · 04-23-2012, 12:42 AM

Unlike you, I've been to my dealershit 3 times already regarding this (see my older posts in this thread). They always say Nissan doesn't know anything about, basically joke about it and make fun of me, because "it's nothing".

Just like you, I've managed to make them hear it (including their secretary) by driving around and turning their head, but so far they've changed everything *outside* the card except the ECU under the glove box, where the noise apparently emanates from.

I've lost my will to continue leaving my car in for weeks waiting for replacements of everything possible in the engine area, rear area and whatever, because they will never accept it's an ECU issue. The latest consensus is that it's something *expected*, by design. I'm gonna march in there as soon as I can and let them compare my car with any of their test Z's, to show them how "standard" this is! However, I don't see any resolution coming from that. They are simply not accepting the responsibility, since Nissan EU/Czech Republic doesn't acknowledge this issue at all.

I simply just don't know HOW to proceed. They're the dealership where I bought my car, mind you. This has been dragging over half a year now.

The problem is that I'm EU and most of you are probably USA. They say Nissan EU knows nothing about this issue! Could anyone provide some Nissan contact (even in English, whatever helps) where *they* could get some information about this? Have any of you tried calling Nissan directly (EU/US) and with what results?

Thanks so much,
I've been living in this nightmare for about a year now!!

Dave print out everything you can find about the noise from this website and hand it over to the dealership. highlight the important info you find.

roy'sz · 04-23-2012, 01:15 PM

It was made clear to me from Nissan North America that they do not take what is said on this website into consideration on any claims made to Nissan OR Nissan North America.

Mee too. I'm still hoping to make them drive their new model car and then mine to prove that the sound is not normal...

fuct · 04-24-2012, 10:22 AM

like i said, the younger you are the easier it is to hear.

OKC Z · 05-03-2012, 06:16 AM

I got the ECM replaced under warranty and most of the noise is gone. There still is a little bit of the whine coming from the same area. But I can finally drive without the radio. I would be a happy camper if it stays that way for as long as I keep the car. They installed the 23710-1EA1B in my '09. At first they played it like they didnt know what it was or what I was talking about. But after 6 shop employees getting in the car and 3 of them confirming hearing it they called tech line. At first they told me tech line had no records of any ECM's making noise and getting replaced on 09 Z and on G37. But hours later nissan tech line came thru and said yes well send you a new one and replace it under warranty. I was really happy being that my car is out of warranty.

I have been noticing a high pitch whine that seems to be coming from the back of the car. It is most noticeable around 70-80mph on the highway when adding throttle. Noise disappears at that speed if I let completely off the gas. Fuel pump issue as opposed to the ECM?

cheshirecat · 05-18-2012, 10:08 AM

It could be the fuel pump if you hear it coming from behind the passenger seat within the partition.

The ECM comes from the glove box area and is constant at anything usually over 1200approx rpm.

Vbp6US · 05-21-2012, 03:50 PM

Bump.

I took my car in for this issue and the CSC issue with the clutch sticking/not returning all the way, leaving slack. Waiting to hear back from them. I got them to acknowledge there is a noise coming from the ECU.

Vbp6US · 05-22-2012, 05:10 PM

Bump. Take your cars in guys. If you have an annoying sound coming from the passenger floor area, it's a bad ECM. To be specific, a bad capacitor is the culprit. Kind of a big deal considering it could throw the computer off and/or catch fire.

Nissan tech line will tell your dealership this is a known issue if you have a 2009.

wackjum · 05-24-2012, 08:06 PM

My car just started developing the ECM whine. I thought I was going insane at first until I searched the Internet and this site and discovered it was not just me.

I have a 2009 Touring, Sport, Nav. I have 32,900 miles but my 36 month warranty ran out in March.

It has gotten worse over the past week to the point where I really cannot drive the car without getting a headache. I tried packing the area around the ECM with noise reduction foam and that made a negligible difference.

Does anybody have any suggestions on how I should approach the dealer for a possible goodwill/split cost fix? Any dealers in the Houston, TX area that I should go to? My car was purchased out of state and I do not have any long-time relationship with any Houston dealer.
