2013 Access CAB Door Bouncing back

Just bought the 2013 Tacoma Access CAB and noticed that I had to close the door harder (basically slam it) to get it closed. Have taken it to the dealership and they tried realigning the door by bending/twisting (gently) and that did not solve the problem. I checked with few other newer access cabs and I felt the same with other cabs. Tech guy told me that there is a vent for releasing pressure when you close the door, but for this 2013 truck, there is only one vent in the middle and that may be too small. According to him, in certain models, they have two of those vents.

I was just wondering whether any of you guys have the same experience with any 2013 models. This is my first truck and I believe the doors are bit rough compared to a sedan but I certainly have to put a bit of pressure to close it completely. Appreciate very much if you can share your experience.
