Car has a rattling noise

this is kind of a loose description. does it do it just parked/driving etc. check for loose or broken shields under car like maybe pins missing or the converter shield rattling against the converter because rivets broke.

Thank You.

Whenever the car is on a bad patch of road it makes a lot of rattling noises inside the car. what could be the possible reason??

i20 automatic. When ever the car is on a bad patch of road it makes a lot of rattling noise inside the car.what could be the possible reason??

Please tell me what can be done to fix it.

if it is a bumpy road or bad patch like you say it can still be what I said or a front end problem so have that checked.
