Today I leaned on the rear hatch and it made a clicking sound like the trunk was open. I tried it and it was not. After getting into the car and starting it the "dummy" light was on saying the hatch was open. It was and would not close. I drove the car anyway and after a couple of miles I hit some uneven pavement and heard the hatch make some clicking sounds. Pulled the car over and the hatch closed.
Now this is where it gets even more strange...
I turned on the headlights as it was getting dark...and the hatch clicked and released! I turned the lights off and the hatch clicked again.
Ever hear of this "electrical demon"???

 

I would look for chafed wires at the accordian shaped tube at the top of the hatch. Your Registration plate lights and hatch button wires go through the same place.

Thanks Chad....I will give that a look today.
