Why is my Ford Kuga's engine making strange noise?

I have noticed that my Ford Kuga's engine is making a strange noise while driving. It's been running smoothly before this. What could be causing this and how can I fix it?

It could be due to a malfunctioning spark plug or an issue with the timing belt. I would recommend taking your car to a trusted mechanic for a diagnosis and proper repair.

Check if your oil levels are adequate and if not, top up as needed. Low oil levels can cause unusual engine noises. If the problem persists, have a professional check for any potential engine issues.

It could also be a sign of a failing alternator or a loose belt. These components are crucial for powering your car's electrical systems and should be checked and replaced if necessary.
