Rattling when wheel goes over bump -- disc brake hardware?

welcome!

does the sound area change depending on the wheel that hits?

 

not that i recall reading, but anything is possible. are you still under warranty?

 

I would definitely take it in to the dealer and have them check the brakes/suspension. Offer to drive the mechanic so they can hear the sounds it makes.

 

The Prius is a heavier than normal car due to the heavy traction battery, motor/generator, and all the hybrid hardware, with minimal sound insulation to save weight.

I'd say that the sounds you might be hearing is normal, and that you never noticed the sounds before with the windows rolled up. Also, the fact that all four wheels are making the same sounds. The odds of something wrong with all four wheels/suspension is low.
