A problem I encountered is water getting into the rear door, not sure if the window was opened slightly or if it has a seal issue. Finally I tried my fingers under the bottom to pull of the door as I pulled the handle too and it opened. It seemed to be making some noise when I pulled the handle but wouldn't open without the extra pull, then water dripped from the latch.
I found 2 drain plugs and pulled them to find sand, wet red New Mexico sand plugging the holes. I cleaned some out with a screwdriver, but it really didn't drain and until I took a drive then opened the hatch and some wet sand had come out the holes, it's getting late, so other than having soaked the latch with liquid wrench, I left the drain plugs out and will look into it more tomorrow. Rear hatch does seem to be functioning normally now.
Going to add this link from the other thread for the handle rubber replacement, seems it might be a good idea to replace it before it gets bad, the current first review has some install tips;

The original cover is prone to melting in hot climates and harden in cold.
