    My 2007 Prius Touring creates high pitch Squeak/Whistle sound while accelerating and braking, But if I put the car on neutral then the sound completely goes away. I have all the holes covered on the both side mirrors and this still occurs. The sound is constant for as long as I accelerate and Brake and the intensity varies with how hard I accelerate or brake, It also does that during regen braking when I leave the accelerator. Anyone have any idea what could be wrong? Thanks.

    My 2011 does that... sounds like the inverter doing its thing.

    It sounds different than the inverter. Its a constant whistle type of sound with varying intensity and I had a 2005 prius before this and it never made this sound.
