Unfortunately I feel I am in the same shoes..
2012 Focus SE Hatchback 5 speed with ~25k miles.
So far, the A Pillar was not properly bolted on, both front seats have had back springs break, AC vent wouldn't move, engine overheat, replaced clutch, factory body panel punctures, and now its in for an engine knock and the carpeting tearing apart.
I'm not sure how much worse your situation was, but after a month worth of Warranty repairs since 5/19/12, I'm getting sick of taking work off to have my car fixed.
If I may ask, who did you contact about the buyback? I'm tempted to send an email to headquarters and the dealer I bought the car from, but I don't want my email to just get "lost".
