Is the noise always persistent or does it only happen intermittently? I'm just wondering because one night I started up the car and heard a high pitched noise (in the 09) but it was pretty faint and easily covered up by the stereo at low volume. After that night I haven't heard it since. Is it something that gets worse over time?
I'm an electrical engineer so I could probably take out the ECU and look for the bad caps or transistors that are causing the squeal, but I don't know if I want to go to that much effort if I can get it replaced under warranty...
