We have a 2014 Focus and love it. Before the clutch packs and some sensors were changed and software updated, we were most unhappy. Ford paid for it all and has extended the warranty on this repair to 150k for all such Focus models, at least that is what the letter said we got from Ford. If yours has problems see a dealer fixes are available and ours is now great. They test it with a computer and actually drive it and the computer tells the tech how severe yours is.
Hint: ours got worse during mountain driving. Guess what I did for one hour prior to taking it to the dealer for the test. The tech said it was the worst he had ever seen.
