I'm having that same damn problem!! I don't know what it could be. I checked fuses and relays. But I don't seem to be finding a fuse/relay that is labeled TRUNK anything.
I took it to the dealer and they said they were gonna charge me $100 just to look at it.
So I said screw that.
I popped off that little black cap that is on the inside of the hatch and there is a little white lever that you can push to the side and it opens the hatch.
