No real news on this yet, but on another forum about the G37 someone said Infiniti told him they're still working on a fix that insulates the ECU (where they say the noise is coming from) without it overheating, and that the problem isn't a safety concern.
Im having the same problem, soft high pitch sound on and off when I accelerate slowly, does it when the radios off or on(I dont have a BOSE system or NAV), would love a solution that I can go to the dealership with as they look at me like im crazy. I really cant stand it.
