Has anyone else had this part replaced? If so, has it been successful so far? Our C-Max will be due for oil change, etc when we return to Michigan and I'm planning to ask our local Ford Service Advisor if they have tried this. I don't believe it was done the other times our car has been in. I need to check our service records once I'm back home. I will update here if I learn anything. It sure would be nice to put this issue behind us.
