My new '06 also has shown some reluctance to quickly downshift and go. Checked with my dealer. He said there was no update for my car. Seems the tranny is setup for best mileage, so a smooth steady foot gives the best response rather than stomping on it. I have to admit, mine gets about 2 mpg more the my '01 across the board. I'd call it a luxury car setup vs a muscle car setup.
