Why is my Ford Fiesta's engine making a knocking sound?

I noticed that my Ford Fiesta's engine has started making a knocking sound recently. I'm worried that it might be a sign of a bigger problem. What could be causing this and how can I fix it?

Maria, it is possible that the knocking sound is coming from a loose or worn-out engine belt. You should check the belts and tighten or replace them if necessary.

Hi Maria, another possible cause could be low engine oil. Check your oil levels and top up if needed. If the sound persists, it could be a sign of a more serious engine issue, so it's best to take it to a mechanic for a thorough inspection.

I had the same issue with my Ford Fiesta last month. It turned out to be a problem with the pistons. Take your car to a trusted mechanic for a proper diagnosis and repair. Don't wait too long or the issue may escalate.
