I don't think the '13 is that much different from the '12, though I'm loving the hell out of mine. It's only been 3 weeks but I've yet to have any issues outside of a door panel that was scratched when I bought it, and that is hardly Ford's fault. :P
I went with the MT though not the DCT that may be why I've been problem free thus far. After reading around the forums here for the last few weeks I think there are two big reasons the Focus has a bad reputation.
1) The DCT has legitimate problems.
2) The people with problems are always going to be louder, and I would also reckon they are also more likely to be the people seeking answers/fixes on forums. People who are general car users aren't going to bother joining a forum if they aren't having problems.
