I have a question for the longer time C-Max owners. I used to own a 2008 Escape Hybrid. About every 30K miles or so, the car would do a "recalibration" event, where it allowed the charge to go down to around 30% (normally it was around 54% minimum) up to around 90% (normally a max of 66%). This was to determine the capabilities of the battery pack, and adjust the charge useage. After this event, it went another 30K before it happened. It was most noticeable when the engine kept running to charge the battery, even at stop lights with the engine warm.
Has anyone seen this in the C-Max?
I personally own the Energi, and I believe we have decided over on that Forum that the Energi doesn't need this, because the car is plugged into the electric grid every night, so the system can perform analysis constantly. But the C-Max is more like my old FEH.
