Rear hatch won't open. Intermittently. Is there a way to manually open the hatch so that i can get to the latch?

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.

If there is no exterior handle to open the hatch you are in a pickle. The rear hatch interior moulding assembly will have to be removed from inside the vehicle to access the lock assembly. This may crack/damage the moulding assembly as it is not designed to be removed this way. Once removed the door can usually be opened manually and then diagnosed for the problem. It may be a defective lock solenoid or latch assembly. I would have a pro look at it as they know how to disassemble these things with minamal to no damage.

Check the hook and latch for any obstructions or sticking. Also check remote button for semi sticking.

you dont say which latch it is but check the part that latches on the stud sticking out. if its closed just pull open handle and manually flip the latch open an should work fine.

Press door unlock switch in car or on remote to release the lower tailgate, even if the hatch is open.

This fix is for 2011 rear manual door.
You may experience some light turns on while driving over a bump or take a sharp turn. Your rear hatch indicator said door is opened.
The courtesy switch is located inside the rear hatch latch assembly. Nothing more but a simple thin lever line leave spring that contacts the ground pole to tell body ECU the door is opened.
The spring is so thin that it bent out of shape overtime therefore when you close the door it doesn't get pushed away from the ground pole far enough caused intermittently false door open alarm.
ALl you have to do is to remove the door latch assembly. Separate the actuator from the latch. Look into the latch you would see a copper like spring one end rests onto the ground pole. Jam your screw driver between the latch housing and spring lightly pride it away from the pole to unbend it. . Manually close the latch and look to see if it gets pushed away from the pole. If it doesn't try to unbend it again.
If you have or know how to use a ohm meter than check for continuity between spring and it housing. You should get 0.3-1.0. Ohm when the latch is open and no continuity when you closed the latch.

Go inside the rear hatch area remove the trim panel and manually trip the hatch release.

Go into the rear hatch cargo area and remove the trim panel over the latch and trip it manually. I know this works have done it myself on my 1996

It sounds like the lock actuator has failed or has a poor connection which won't allow the latch to release. What you will need to do is remove the inside rear hatch panel to access the lock actuator. Once you get to the latch use a flat screwdriver to release the latch being careful not to damage the glass.
