What is the most reliable engine for a Ford S-Max?

I'm wondering what the most reliable engines are for a Ford S-Max. I've heard mixed reviews about the different options and I want to make sure I choose one that will last. Any advice?

In my experience, the 2.0L EcoBoost engine is the most reliable option for a Ford S-Max. It has plenty of power and has been very durable for me. I would definitely recommend it.

I've had good luck with the 1.5L EcoBoost engine in my Ford S-Max. It's smaller but still packs a punch. As long as you stay on top of maintenance, I think it's a great choice.

My mechanic always recommends the 2.0L Duratorq TDCi engine for its reliability. I've never had any major issues with it and it has good fuel efficiency too.
