Driver Side Rattle when low idling - PLEASE HELP

Hi all,

I am the owner of 2013 Prius C Three - one of the orange ones

Been the owner since 2017, bought it with 17k mi and it is now at 103 almost 104k mi.

It has had regular maintenance, fluids changed, and recently the radiator fan assembly was replaced.

I am now hearing a rattle which, to me, sounds as if it is coming from the front left quadrant of the vehicle.
The noise only occurs when the car is idling at its lowest rate (frequency? not sure) and not all the time. It appears to happen only after I have been driving the car for an hour or more.

Any suggestions or ideas as to what this may be would be greatly appreciated.

Thank you kindly,

A very concerned Prius owner
