Do the blue charging lights on top of the dash flash one after the other when this happens? If so, a charging timer is set in the car, and you haven't tried to charge during the time(s) - most likely overnight - when the timer allows it. Try pressing the timer override button on the lower left side of the dash right before trying to charge. If I remember correctly, it has a clock icon with the word "OFF" under it, and maybe a line through the clock image.
