I think this might be a normal thing, but I was curious why it does this.

When I start the car, or sometimes when it goes into idle mode, it’ll make a noise that sounds like someone left a cellphone on vibrate in the engine compartment for a few seconds before stopping.

What is it doing? I have wondered since I got it.

That's the vacuump pump for the brakes. It runs intermittently as needed to maintain a vacuum in the system and in most cases will do so right at startup.
