Your right about the firmware update. My mileage dropped about 5% after the last recall update. Honda claims this was done to preserve battery life, in other words, the computer will not allow the battery to discharge fully, so this in turn increases the work for the ICE, and decreases MPG.
If it makes the battery last longer, I can live with the decreased MPG.
