Rear hatch is locked or unlocked with a key. (if equipped) • To open the rear hatch, insert the key into the lock, turn it to the unlock position and pull up the rear hatch by pressing the handle (DOOR). You can also lock/unlock the latch (but not release it) with the central door lock system. • If unlocked, the rear hatch can be opened by pressing the handle (DOOR) and pulling the hatch up. • To close the rear hatch, lower and push down the rear hatch firmly. Make sure that the rear hatch is securely latched.

You can get it open in two ways: By using your key fob and remotely opening latch or by pulling inside panel on rear hatch and manually pulling lever to get latch to release. Most times when you cant get rear hatch to open normally is because cable from outside release handle to latch broke. Have cable and release mechanism inspected and replace worn or broken parts as needed.

Replace the broken door latch handle and it should work just fine.

This is extremely common!
The micro-switch inside the glass hatch release is faulty, telling the door that it is partially depressed, thus shutting down opening for safety reasons.
You can verify this by opening the glass hatch (there is a access panel at the bottom of the door on the inside), removing the trim cover from behind the glass handle (two philips screws and one plastic push in fastener), then unplugging the glass handle.
Your door will now function normally, but without glass opening ability until you replace the handle.
The handle only takes a few 10mm nuts to remove and can be changed in a few minutes. It retails for around $35 from your dealer.
