What are common issues with the Ford S-Max engine?

I recently bought a used Ford S-Max and have noticed some issues with the engine. Are there any common problems I should be aware of and how can I prevent them?

It's always a good idea to have a trusted mechanic inspect the engine and look for any signs of wear or damage. They can also give advice on proper maintenance and potential issues to watch out for.

One common issue with the Ford S-Max engine is faulty spark plugs. If you notice misfires or a decrease in performance, it's important to have them replaced as soon as possible to avoid further damage.
