The noise doesn't appear like it is going anywhere and is a byproduct of normal operation (making resolution all the more difficult). Not being a safety concern there is little legal ramification in most states.

The noise has a direct correlation to the throttle motor driver, or fuel pump, proving what does what inside the computer is never going to happen or at least on my level it will not.

DRebillard- The issue highlighted in this thread does not apply to models from <2007. This is only noticed on vehicles with the dual throttle body setup and VQ35VHR motor, which the does not have for your year. I do not know what you are referring to but these engines do tend to make some funny noises. Other than that I do not know what to tell you.

Steve, so what is the most realistic fix for this?Has any member was able to get a fix from the dealer?

This noise is so unbearable that I can hear it when i get out of the car and at home for the next minutes or so.

Steve, you really think that a person can't lemon a car if they can't fix this. After all, i didn't buy the car to have this POS noise.

The TCM is actually submerged in the transmission pan on all 03.5+ models with automatics. You are correct about power transforming modules. Headlight ballasts hum, which is why they are as far away as possible. The ballast in my kitchen has recently started doing that funny buzzing thing indicating my "Honey Do" has just increased.

I think you have something unique or Canadian my friend, not all of the things are the same and you very well may have something that is just slightly different. Unfortunetly we here in the states have some issue retrieving parts information indicating there are a few small differences. Nico has a bunch of members from the Great White North maybe some of them can help you a bit, check out our G forum. One of the things I tend to harp on is the cold weather making anything worse, but your issue is not the same.

I understand your frustration although any information I have is by no means official in purpose and is a casual conversation....please don't send me a subpoena. Typically I stay away from issues like this that may end up in court but I really think this deserves some attention.

Here is the dilemma, the majority of people cannot hear noises over the 20kHz where this noise is heard. I can actually hear this but more than 8 of my 12 co workers cannot. Depending on your personal hearing range you may never hear this basically. I consider myself pretty sensitive when it comes to noises like this. Actually I feel like I can feel the vibrations of some noises, well not a weird sixth sense sort of way more or a doing it for a living way. I can hear this noise over the radio in some cases, I spent a weekend driving an EX while I was contemplating purchasing one and it made that noise. I didn't end up getting it as my DW did not care for the look, but she couldn't hear the noise even in the passenger seat.

I have been pestering everyone I know for an answer to the big question of what is going to be a fix. As you can see if you read through some of the other larger threads in this forum some of these issues can be known of for a year before a sufficient resolution is found. Typically with mechanical things like this and the EX rack and pinion concern from 08 a whole new component needs to be built. There is a significant problem with this case though, and that is the fact that in order to redesign the ecm they will have to reapply for federal certification depending on the route cause and remedy but the rules are very strict. Once I hear something I will be sure to post it.

To the best of my knowledge there is no incidence of a suitable repair as the component that we suspect and the possibilities are very limited for a repair that will fix this without a consequence. It's a butterfly effect type thing.

SteveTheTech wrote:1-You've already lowered your 09? It is actually there call whether they mention things that the owner changed so if there is a problem down the road they will now what is actually a manufacturers defect and what should be warrantable, this is nothing unique to Infiniti and is standard practice. If you have a good rapport with the service staff (who are people first and should be treated as such and employees of a company secondly).

2-Have you read anything I have said in this thread? The acknowledge the issue and the R&D team is working on it. One of the other members here is getting a final prototype, that typically means the final testing phase is done. Ordering a new ECM isn't going to fix anything because the part numbers are the same...meaning the part is the same....meaning it will do the same thing.

3- Now listen here Ted is a great guy I have worked with him on a few problems. There is certainly no reason to publicly threaten harm on someone. He is actually the reason you have an answer. It sounds like your techs might have gone the long to find the obvious, meaning they must not have seen this before.

Obviously the EX has this issue you are in the ex forum. You have done all of that complaining without even taking the car into the dealer once? Really?

SteveTheTech wrote:The replacement ecm is on restricted availability meaning unless you have one of the cars involved in the long term test (as the member here who posted a part number is/was). You cannot go into the dealer and demand this number. Ted was right, no matter how bluntly it was put to you...there is no mass market fix yet.

Given the safety related recalls from the other Japanese makers a noisy servo inside the ecm is not too bad...imo.

I think you need to find yourself a new dealer, if your dealer has not heard of this concern yet they might not actually see allot of new Infinitis. There are too many dealers in your area to work with a dealer that cannot address this issue. I know at my dealer the service advisers know about this concern and are doing all they can to ease the minds of the owners facing this concern. Your negative impression might have more to do with poor communication in your current dealer.
