What is the most reliable engine for the Ford Fiesta?

I am considering buying a Ford Fiesta but I am uncertain about which engine option to choose. I want an engine that is reliable and won't give me any major problems in the long run. Any recommendations?

I have been driving a Ford Fiesta with the 1.0L EcoBoost engine for over 5 years now and I must say, it has been incredibly reliable. I haven't had any major issues with it and it also offers good fuel efficiency.

In my experience, the 1.5L Ti-VCT engine is the most reliable option for the Ford Fiesta. It may not have as much power as the EcoBoost, but it's more affordable and has proven to be a durable engine.

I would highly recommend the 1.5L TDCI diesel engine if you are looking for reliability. It has a good balance of power and fuel efficiency, and the diesel engines are known for their durability.
