we've also noticed that the overdrive for the '09 automatic doesn't come on as quick as the '08 auto sedan after climbing a hill in the 3rd gear . Wonder if the computer for tranny is not calibrated properly in the '09 .

Its not a calibration issue, its a learning ECU issue. You usually don't gas it hard in 3rd going up hills, so your 08 already knows just to go down to O/D. The 09 still needs some time to learn your driving habits.

Could be just the time of year as cold weather and winter gas formulations and short runs and winter tires arent the best time to expect your best fuel economy..In my 08 sedan in summer highway driving i can get 130kms before the first bar disappears,in winter in city traffic its usually gone around 90kms..
