From speaking with my service rep, this is a pretty well known issue with Fiesta's in general. Honestly, it sounds like it will happen to pretty much all of them if they are driven in a climate where it snows. I don't understand how Ford's engineers could overlook this issue in the first place, and why on earth Ford would choose to keep manufacturing the cars with the faulty intake and only replace them when they fail. You figure that since they have a re-engineered part that fixes the issue, that it would be cheaper to incorporate the new part into the assembly line then to deal with the warranty claims of replacing the entire blower assembly when it fails. Even with a large percentage of these cars never seeing snow, how hard is it to stop producing the old part and only supply the assembly line with the new intake? At the very least they should be requiring the selling dealer to replace these faulty intakes with the new style one prior to delivery in locations where snow is a normal annual occurance.
