I dont have any sound in your video. Maybe its my phone. Yes lots of people hear annoying buzzing sound at low throttle. There are a few threads about cicada or cricket noises. No one knows what it is or has fixed it. Some vehicles do it some dont. Mine gas OR makes annoying buzzing sound you can hear it louder with the windows down, I think it is some type of electrical grounding issue. My hybrid did not make the noise.
