The problem you are all experiencing is in the shotty electronics Chrysler puts in these cars. I was recently on the plan with an individual from Chrysler's QA Dept and he admitted to "struggling" with the electronics.
The sluggishness / hesitation or whatever you want to call it is due in part to the throttle by wire DC uses. The other part is the tranny which is also 100% controlled by wire except for the internals.
The fix...recalibrate your Throttle Positioning Sensor (TPS) by followin the steps on this site. I have to say it appears to help 99% of the users on this site. (It didn't help me)
You can also go to the dealer and get the latest ECU Flash. Some claim this will help too.
I've tried both and my car is still a POS but I will keep reading and searching for an answer. Meanwhile my car is up for sale.
