Funny you should mention those two. In the US market they both shipped with a quite defective Ford-developed DCT that would rarely last 50,000 miles before failing. I do not believe whatever the problem is with these transmissions are fixable because the replacements will also fail short of 50,000 miles. I actually own two Fiesta's, one with the 1.0l ecoboom which is currently dead at 84,000 miles due to the plastic used within the engine getting brittle and failing and causing it to catastrophically overheat very quickly (just about all of these 1.0s will fail between 75,000 and 85,000 from what I've seen). I also have a i4/manual version which is about to hit 200,000 miles and runs great. The key in the US market is to get a 5 speed version if you want mostly trouble free ownership. The Fiesta is almost the perfect small car that was mostly ruined due to cost cutting in areas that there shouldn't be any cost cutting happening.
