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

I've been researching the Ford S-Max and it seems that there are multiple engine options available. Which one should I choose for the best reliability and performance?

In my personal experience, the 2.0 TDCi diesel engine has proven to be the most reliable and efficient choice for the Ford S-Max. I've had mine for 5 years now and have had no major issues so far.

I would recommend going for the 2.3 EcoBoost petrol engine if you prefer a more powerful and responsive driving experience. However, keep in mind that it may require more frequent maintenance and fuel costs may be higher.

If you want a balance between performance and efficiency, the 1.5 EcoBoost petrol engine is a solid choice. Just make sure to keep up with regular maintenance to ensure its reliability.
