What are the Common Issues in the Ford Focus Engine?

I recently bought a 2015 Ford Focus and I've been experiencing some issues with the engine. It makes loud noises and seems to struggle while starting. Can anyone tell me what might be causing this?

Hey there Tom, it's common for Ford Focus engines to have issues with the timing belt and alternator. I would recommend getting these checked out as soon as possible.

Hi Tom, this could also be caused by a faulty fuel pump or spark plugs. It's best to have a mechanic take a look and diagnose the issue.

Hi Tom, I had a similar issue with my Ford Focus and it turned out to be a faulty air filter. Replacing it solved the problem.
