Why is my Ford S-Max's engine making loud knocking noises?

I have a 2019 Ford S-Max and recently it has started making loud knocking noises whenever I start the engine. This noise is getting louder and more frequent. What could be causing this and what should I do?

It's possible that your engine has a faulty connecting rod or piston which can cause loud knocking noises. I suggest taking it to a mechanic as soon as possible to avoid further damage.

Make sure to check your oil levels and replace it if it's low. Low oil can cause knocking noises in the engine. If that doesn't solve the issue, it's best to have a mechanic take a look.

Have you recently had your car serviced? It's possible that the oil used was not the recommended type, causing the engine to make strange noises. Check your owner's manual for the correct oil type and get it changed if necessary.
