Had my C Max Hybrid into the dealer for it's first 8000km service and while it was there they upgrade/flashed the PCM and now I am finding that my milage went from 3.8L-4.2L/100km to 5.1L/100km! It's now running longer on gas then on Electric (Battery charge on 1/2 to almost full) and not switching over to electric as often! Anyone else have these concerns? Right now VERY upset at this as this is my first Ford car... have owned all Chevy's in the past. Loved the C Max reviews so I bought it. Want my C Max to run as it did prior to flash! Any suggestions?
