From the article it sounds like it affects ~1% of cars, and causes a complete loss of ability to brake. The one guy in the article linked in the comments had it total his Ferrari in June 2021, bought a new one, and it happened to the new one almost immediately too, in July 2021. Doesn’t sound THAT rare for such a serious issue. Ferrari’s themselves are pretty rare though, so total numbers are low (23.5 K in the states, so 1% affected would mean about 235 cars).
