Strange clinking sound - Audio file for help**

I've started to notice this strange clinking sound. It doesn't happen all the time, but usually when I'm driving below 10 mph. Here is a link to the sound that I recorded: (I will post the link once I can)

Can anyone help me out? I have a Prius Prime 2017 Plus with 80k miles.

Thanks!

 

I will post the audio clip asap

if anyone can help i would appreciate it, thanks

 

no, it only does it when i drive under 10 miles an hour. only when driving.

 

I need to check. What are you implying?

 

I am sorry for the late response, Yes the engine on when it makes the sound.

 

SOLVED ** My TPMS tire sensor came lose and it was rattling around with the watch battery inside the tire. so strange!
