Why does my Ford Fiesta make a rattling noise while accelerating?

I recently noticed that my Ford Fiesta makes a rattling noise when I accelerate. It's not very loud, but it's definitely noticeable. What could be causing this and how can I fix it?

This could be due to a loose heat shield or a failing catalytic converter. I recommend taking your car to a mechanic to get it checked out.

I had the same issue with my Fiesta and it turned out to be a loose exhaust pipe. It's an easy fix, just make sure to get it taken care of before it causes any damage.

The rattling noise could also be caused by a worn out serpentine belt. If that's the case, you should get it replaced to avoid any further issues.
