Yea, I agree with everything you said. It just seems totally inexcusable. Also, the dealerships should have all been put on notice about this problem rather than trying to deny it's existence.

I had a 2006 model that I got rid of because of a sporadic problem with the radio that never went resolved... thought getting the 2009 I would be problem free.

 

Noise issues like this are so difficult to get anyone at the dealer to acknowledge... all of their "techs" work for hours a day amidst impact wrenches and other loud tools, that their hearing is shot! heh

 

You would think the dealer/service center would have a check list of issues. ie
If customer complains about a mystery high pitch noise when the throttle is hit in neutral or in drive and the ac is turned off and the radio is turned off and if the mechanic can not hear it and it happens in hot/cold/wet/summer/winter env .... check the ecm

 

I got my ECM replaced and the key reprogrammed today and NO MORE NOISE!!!!!!!!!!!!!!!!!!

Thanks to all on the forum, I would have had no idea this was a known problem without the forum.

 

^^ Good for you! It's nice, huh? I ride around a lot now, no radio, just golden silence and the exhaust. Can't wait till I get my Tannabe setup....

 

Well, one bit of bad news- my hypertech won't recognize my new ECM! Plus, my ECM shrieks like banshee from 7 to 7.5k I have noticed. Very unerving, and it seems as if it loses power right at that point.

 

Short story: Took my '08 G37S to Metro Infiniti for the high-pitch frequency noise. Ross Aragon said they couldn't hear it and gave me my car back. I asked them how long the test drive was and they couldn't answer me. I then asked them if there was anything else I can do, and he said no. I sent him an email to the threads here and documented our conversation. I then contacted Consumer Affairs.

Emily at Consumer Affairs and she tells me that there is nothing Infiniti can do on her end and Metro Infiniti was not able to recreate the "high-pitch frequency noise." I then asked her if it was possible to get her stance on the issue in writing as a memo, and she said NO. I asked her if I can get my own report in writing and she said NO. I asked her if there was any documentation or a standard procedure for test drives to ensure that the dealership did a proper test drive.

Her reply was that every dealership is different in their method or process. I asked her if Infiniti is aware of this issue and she said not for the '08 but for the '09. She further added there is nothing Infiniti can do since their is no TSB for this.

Does anyone know of a dealership in SoCal that is familiar with the issue and I can actually entrust to get this fixed? Sometimes I can't believe how dense these people are. I'm usually pretty damn busy, but I will take my time to file a claim with the BBB if I can't get this sorted out.

Wow, that's pretty crazy - so Infiniti is recommending replacement for the ECM for 2009s, but not any other year unlucky enough to have a bad ECM? My dealership didn't give me any problem at all....you do have a pretty extensive list of mods - perhaps they are simply blaming your mods, nut not telling you that...

 

Has anyone in the metro NY area successfully fixed this high pitch noise?

 

I can confirm that Infiniti Canada also takes this ludicrous, and in this Internet-day-and-age, unbelieveble position on issues and will not reply, even in a voice mail let alone in writing, with any substantive response on known issues.

The customer service strikes me as much closer to 1980's Hyundai than any upscale brand.

 

so there's still no TBS for this? unbe-fvcking-livable!
is there a part number or it's just replacing the ECM?

 

Complained to dealer, did a ride along, got fixed in 2 days. New Ecm did the trick, NOW I love my G, so much more enjoyable.

 

So my infiniti service department says that they don't know how to fix the noise because there are no bulletins or advisories on it, and they chuck it up to "its a characteristic of the car".

Is there a refference number I can use for the fix when I call Consumer Affairs because right now I am at a loss

 

seems to be hit or miss with consumer affairs for some people. But just call consumer affairs and tell them about your problem. Their regional rep will give you a call back and they are the ones that should know how to fix it.

 

Finally got a response from my dealer in Windsor, Canada- looks like they now acknowledge the need for a ECM replacement.
