Having my 2011 SE for a week now (tomorrow) I haven't experienced ANY jerking issues or irregular driving patterns. I HAVE noticed though out of the gate the acceleration difference now that it's learning my driving patterns. I know one week isn't enough for it to be fulyl seated with my patterns, but there is ALOT more pop when I put it down.
One thing that I'm particuarlly fond of is the cornering technology. The car senses and has the ability to cut power OR ADD depending on the corner. This had made for some excellent and fun driving. Plus it's made my motion sickness peak it's ugly head.
Goodluck!
