Bumping an old thread, but this problem just started with me too. I talked to my Nissan service tech and he told me the ECM is covered under an 8 year, 80k mile warranty. I will be printing out this thread as well just in case they think I'm just losing it.

Good luck. The dealers here in Socal denied my warranty claim to replace the ecm, citing that it is "normal" because a few of their 2014 models also have this noise.

I'll report back in the next few weeks when I find some time to get it done. Crossing my fingers!

Anyone know where I can find more information on Nissan's warranty?

*Edit*
Just looked up my warranty information. Yep ECM is 8year, 80k warranty. I'm going to bring a copy of that to the dealership as well.

Make sure you ride along with the tech to show them how replicate the noise, otherwise they'll just play dumb and say they cant hear anything.

I have yet to hear this sound yet on my '09. Maybe the headers drown it out.

MyKindaGuise · 02-20-2014, 08:22 PM

Does this only happen with the engine running or does it happen if the car is just in accessory mode?

I have a whine now when I go into accessory. I cant hear with the car running because the car is so loud...I think.

Same. If I'm in neutral in accessory mode I don't hear it. But if I put it in any gear in accessory mode I hear it. Hopefully I don't start noticing it now that I read this thread haha.

Must forget by springggggggg

DEpointfive0 · 02-20-2014, 09:27 PM

^the fuq?
That sounds weird, that's not the normal ECU whine.

I have no idea. I had a whole slew of issues come up before fall and Im sure this is just related.

ABS/WSS has failed on my car and my rad fans don't want to work too.

Took it to my buddy who is a master tech at a Nissan dealer...says he has never even seen or heard of it.

Tried consult 3 and it crashes. Sigh

Acc mode and On won't do it. Only when the car is on. When it is a cold start, you actually have to rev over 1k to get it to make a sound. Once you let off, it stops. As soon as the car slightly warms up, it's continuous.

My buddy heard it too. I am friends with the tech at my local dealer so he won't BS me. Hell it's easiet to hear at idle when the car is the quietest.

Yeah man that's not the ECU whine. The best way I can describe the ECU whine is the very faint sound a dog whistle makes. It's super high pitched.

wackjum · 02-21-2014, 12:14 PM

When I had ECU whine, I could not hear it if the car was at a complete stop. It would start up around 10 mph and build in intensity up to around 30 mph when it was constant.

It was a very high pitched noise that gave me a headache within minutes. Some people could not hear it at all though. But I am one of those people who can hear a TV screen that is on so I guess I am sensitive to that range.

The tech could not hear it but he was familiar with the existence of the problem and replaced it under warranty no questions asked.

Zbrah · 02-21-2014, 12:52 PM

Mine comes on right around 1800-2500 rpm in any gear, it gets louder the longer I'm driving within this range. Everyone who rode in my car have heard it, but according to the service advisor at OC Nissan GG, it's "normal" because they hear it on some of their 14' models. I cannot accept this and will be making a call to corp very soon.
