I'll be doing this myself... warranty was toast in less than 16 months! :lol:my 04 SOP did this years back. if it is the same noise i am thinking of it is one of the actual actuators going bad. mine was the one in the rear hatch. take it back to them and let them replace it, and ask if you can see it when they swap it, or even the new part before they put it in. it is suprisingly whimpy in size and makes me wonder why DEI's aftermarket actuators have to be 2-3 times that big for a door lock actuator.
