I drive multiple cars depending on my mood. Ford engines are ranked in the top 5 for reliability, and number one among US companies. The Fiesta 1.0 gave me 70mpg on the interstate, and I would buy that car (or Focus) if the Insight did not exist.
The Ford 1.0 Ecoboost Turbo 3 cyl has a wet rubber/ plastic timing chain arrangement, which scares me. I wonder at what age they are looking at reliability, because the 2 year reliability is a completely different thing entirely to reliability at 5 and 10 years... and so on. Plus, reliability need to control for cost of repairs as well - and whether a failure is a minor fix, or a total loss/ replacement.
The stats that show how much more dependable Japanese technology is, is hidden in statistics that don't really tell the full story.
Though in principle, Ford do make good stuff; they have had a major issue with automatic transmission recently, especially diesel automatics - so, is this whole vehicle, drivetrain, or just engine - and by what time-frame?
If you were to look at 10 year reliability of whole vehicle, then Ford would be leagues behind their Japanese peers, along with all the Euro manufacturers too.
Though, I agree that Ford could be the best Non-Japanese producer in terms of reliability.
