I noticed a very faint but annoying buzzing sound while accelerating at slow speeds (20-40MPH). It sounds a little like static that or disturbance you might hear from speakers, but the stereo is off. It goes away as soon as I take my foot off the gas pedal.

Has anyone else experienced this?

 

I have experienced this with other cars. It is typically a result of the exhaust system touching up against something on the underside of the car. Simple fix...
