It's the brake booster. Nothing to be alarmed about, all of these cars do it.

Does it do it every time u press on the brake? If it does, then it means the master cylinder/booster is going bad.

Turn the key to the "on" position without starting the car. The "buzzing" should occur after pumping the pedal 3 times.
