Why is my Ford Focus making a rattling noise while idling?

I recently noticed that my Ford Focus is making a strange rattling noise while idling. It seems to be coming from the engine area and gets louder as I accelerate. What could be causing this and how can I fix it?

It could be a sign of worn out engine mounts. I suggest getting them checked and replaced if needed.

Check your exhaust system for any loose or damaged parts. This can also cause a rattling noise.

I had a similar issue with my Ford Focus and it turned out to be a loose heat shield. Get it tightened or replaced to get rid of the noise.
