I have the same problem. With the little mini key in the remotes I can open the trunk manually just fine. But neither the remote actuator nor the interior button will open the trunk. It makes the clunk sound like it is opening the trunk, granted, however the trunk stays closed. BTW it does suck down and close/lock normally. I don't get it. I messed with it for a while, and it worked again a couple times, but then nothing again. Frustrating. I really don't wanna spend a grand to save myself from manually opening the dang trunk, but.....

If you find a solution, please let me know. Thanks.
