There is a recent TSB for this issue. Your description sounds more like the issues I was having with doors not opening when pulling on the outside handle. Door is unlatched but motor doesn't pick up until you really pull it open hard the first couple of inches. Or grinding / groaning after the doors have closed followed by the door chimes. Or when the door closes it groans and pops back open again. A google search for 'entourage power doors' or 'sedona power doors' will show lots of people complaining of this issue.
I had the tsb done on my van and am quite happy. The doors are nearly silent when the open and close now with a solid click as they latch.
Text version of TSB from HyundaiNote the job took a day and a half for me (loaner was provided) because there is so much dissassembly to be done and my dealer wanted it done right the first time.
