I also think it's premature to say the Focus is meant to "hold together until the warranty runs out". The DCT in has not been a statistically significant problem on the Focus. On TrueDelta, probably the best and most "live" reliabilty site, none of the Focus problems are transmission related.
We complain on this forum significantly more than the standard population. The Focus has actually been one of the least buggy launches for Ford in the last three years. The Fiesta, Explorer, Escape, and Edge have all had more issues. The early Explorers were nightmares.
