I have a 2012 automatic as well and if you try and punch it while the engine is cold it does the same hesitation everyone else describes. I've not done that once but I know it's just something that happens to every car, just let your car sit like 10-15 secs before you put it in drive. Also I would not do any hard acceleration until your car is warmed up. Just my opinion.
2012 MCA 6 speed auto.
