i have an '08 SE that has the electronic latching mechanism. luckily i have not noticed any irregular action out of it.
i probably use my hatch at least twice per day everyday, except on the weekends sometimes. it all depends.
i have heard it struggle to close at times, but this is because i fill the cargo area up to the hilt sometimes. also, im not exceptionally easy on the slamming of the tailgate. i dont try to slam it, but sometimes it gets a pretty good close.
i dont know where any test points could be found for it, and im pretty sure you're going to have to take the tailgate apart a bit to get at it. but if its the actuator going bad, you will be able to see a Voltage spike before it or a drop after it (it being the actuator motor, which im guessing is part of the mechanism).
does the problem happen everytime? if so, it could be purely mechanical, namely the latch or the post may be bent, or out of whack.
just thinking out loud. good luck.
