Rear hatch won’t open

Help! I own a 2011 ML. The rear hatch would not open using the key fob or the controller in the side of the driver door. You could hear it trying to open or close, but it would not open or close. There was nothing stuck inside the door. Recently it will not even try to open or close. In addition the interior light stays on while driving the vehicle, because the hatch seems to appear that it’s open. We tried to go through the back seats, removing the Cap on the lever and opening the door manually, to no avail.

does anyone have suggestions of what I can do next? I’m hoping that if I at least got the back hatch open I could try to reset it. any help is appreciated, thank you in advance!

When you try to open it with the Key fob, do you try lifting the door with the outside handle?

Did it rain heavily recently?

Use the key fob to open all doors, then crawl into the cargo area and remove fuse #40. Then see if you can forcibly open the tailgate using the outside door handle.

the black plastic piece under the chrome trim on hatch , it’s really not a handle. But I believe if you press in on it the hatch would open, when it works correctly!

There is an emergency release on the inside of the tailgate. See if you can use that to pop it open. If that works, you probably need to replace the lock actuator/mechanism.

Rear hatch stuck closed

Yes I did see this you tube on this, this is exactly what my ML is doing , but the emergency release on the GL in the video works and it’s a different style than what’s on my ML, I am at wits end!! I am going to go to an Indi shop here in Ft Myers area! I really appreciate all the help on this form, especially Maj .Dundee!! Thanks again!
