My 06 does the same thing -- a hesitation if you roll back on the gas after a decel -- mostly poking in traffic. It IS annoying. No problem at higher rpm's.

I got into a thread here right after I got the car and everyone said the 00-05's do the same thing -- saying it is a fuel cutoff matter.

I have not had the car back to the dealer yet, but will note this to them, but not hoping for any rspolutiomn
