Glad to hear they bought your car back. I have a 2006 G35 coupe I bought used in mid-2007 and a high-frequency noise started to manifest itself about six months ago. Mine only occurs under load (if you rev the engine in neutral, no noise) and is not terribly loud, but it still irks the crap out of me. This is clearly a known issue because G35 and G37 owners are having the same problem. The dealers are replacing ECUs to remedy the issue and some owners are reporting that the noise returns while others assert all is well. I won't buy another Nissan/Infiniti again, despite my strong desire for a 370Z, until they get this issue sorted.
