my truck as well does not downshift, it bogs out in a second gear acceleration, and i have had to floor it sometimes just to get it going. it amazes me that these vehicles passed testing. i think it has to do with the change of the gear ratio. My 05 was faster. just recently it started delaying going into gear from park. it takes about 5 to 7 seconds for it to engage into drive. I have had a number of issues with this truck and only wish i kept my 05. I think i am going to trade it for a denali in 09' Or if they figure out the issues maybe trade for an 09' h2.

you know i noticed that mine is...for lack of a better term, bogging down a little starting out. I thought it might be due to me using regular fuel in it. I am going to take up with hi test to see if that helps it. How many miles are on yours? around 7K on mine
