At least one of the configurations of the 2012 Ford Focus/Fiesta transmission had issues. The mechanic at the dealer agreed it was a problem. Ford never acknowledged their fault as far as I know. A firmware update about a year later seemingly fixed the issue. Why wouldn't they acknowledge the issue and tell people they're working on it? Liability issue?
"Ford has acknowledged the potential for transmission problems in letters to owners and dealers. It has extended the warranty but has not recalled the vehicle."
