It was one of those "silent recall" deals for a while. People bitched about this problem since day one with the SVT. It took them about a year to fix the problem with the PCM, and until now you wouldn't know about it unless you told Ford about the symptoms. But I guess just now they are making it public.
This seems kind of shady to me, but you can't blame Ford for trying to space out all the Focus problems over a longer period of time.
