Back hatch is not catching the latch to close. My

You will be needing to find a helpful body shop and ask them to either adjust your hinges and latches, or, replace parts that are broken.
God bless your efforts.

Bad hatch latch batch or misaligned catch. Detach hatch latch and replace with new batch. If catch is sprung, simply pull the latch. Realign catch with hatch.

The two most common causes are rain water leaking in or the ac drain being clogged up. I would vote for rain water if the entire carpet area is wet.
Could be coming in around the windshield, or one of the door gaskets.

There is a spring in the latch assembly that pulls the catch open when you press the button/lever. It may be broken which will need the unit to be replaced. Use something like a round blade of a screw driver and open the catch as you press the button/ lever.

try using the handle while prying up on the locking clip, the pin should pop up allowing you to close the lid

If, when closing the rear hatch, it hits "hard" just before it reaches the closed position; it is very likely that the latch mechanism in the hatch is "stuck" in the latched or closed position already. This is a fairly common occurrence and takes less than a few minutes to fix. Literally.

In order to allow the latch to close around the mating piece on the car body, it will need to be opened first. To open a closed latch mechanism, you will need to simulate opening the hatch from its normal closed position. With the hatch open, look at the latch mechanism. It will align with the bar on the opening of the car. Adjust the hatch / your view to see how the mechanism would be wrapped around the bar on the body - keeping the hatch securely shut. Once you see an opening in the mechanism described above, slip the shaft of a sturdy screwdriver into the opening. Apply a pulling pressure outward - away from the latch on the screwdriver with one hand, and with the other hand (or with the help of an assistant), operate the handle / lock of the hatch the way you did when the hatch was closed. Immediately upon operating the handle / lock, the latch mechanism will unlock, and the pulling pressure of the screwdriver simulates the hatch being pulled away from the bar on the car - and seemingly magically - open allowing the screwdriver to be pulled out.

Next, you'll need to determine and correct the cause of the latch being in the wrong position. It could be something as simple as someone pushing the mechanism shut when the hatch was open; or it may be caused by a poorly lubricated mechanism that is not snapping into a fully open position. When this happens, it is likely the the closing motion of the hatch actually snaps the mechanism shut when it is stuck on the leading edge of the latch - instead of in the "throat" of the latch (where the screwdriver was). A liberal amount of a dry lubricant such as silicone or graphite applied to the mechanism and "worked in" through repeated opening and closing motions of the hatch would be a good start. Resist the temptation of using a wet lubricant like oil, grease, WD-40, etc. as these attract dirt and dust - which can interfere with a nice, fluid movement of the these latching parts. If there is already a lot of dirt, dust or rust, build up on the latch mechanism, it should be cleaned as good as possible before applying lubricant. Use an electrical contact type cleaner as these clean, degrease, dry quickly and leave no residue.

If you are unable to to get the latch to work - have your mechanic or auto servicer look at it. They should be able to quickly diagnose and free the latch. Most will not even bother to charge you to do this - if this is the cause of the problem.

I hope this helps & good luck!

The hatch is probably "jammed".
Has the hatch opened by itself while you are driving? That is a symptom....
Using a second person/helper, press the "open" button while you pull hard to pop it open.
If it opens, then the lock mechanism needs adjusting and tightening. There are two bolts that hold the catch hook. Once you adjust the catch, be sure to "open" the latch before you close the hatch. (rhyme not on purpose)...

Hope this helps!

I think that I can help you. It sounds like your drain-tube is plugged up. Get in the passenger side, and pull the carpet back from under the glove box. Look for a black rubber pipe that goes from a black box, and pokes thru the firewall, on the passenger side. Remove the hose from the box, and have a container ready to catch water. If water comes out of the black box, your drain hose is plugged up. Clean out the clog, and you will be golden.

try reajusting the latches so they catch
