I'm not that concerned about the durability of the mechanism. As has been pointed out, there are lots of other moving parts in the vehicle. As long as Tesla did a good design it should last the life of the car. No one is talking about the reliability of the pano roof or the automatic rear lift gate...
On the other hand, I am slightly concerned about the durability of the handles themselves. They are subject to wear and tear (scratches etc.), and if the bare aluminum gets exposed it can corrode in the salt environment. I've had aluminum door handles on other cars do that.
