my car is making this weird noise, should i take it in?

I drive a 2013 toyota prius (don’t know the engine) and have already had a few issues with it. i had to get the roaders and back breaks replaced a few months ago. it was making a similar sound before they were replaced but it sounded like it was coming from the back of the car more and was lower, more like a grinding sound. my car feels fine to drive but with the roader/break issue i didn’t take it in when i heard the sound and ended up having to tow it. i would take it in just in case but money is an issue so i wanted to check here first.
