Power hatch issue

Whenever I open my power hatch, it opens, sounds the warning alarm, and then closes automatically. Anybody ever seen this issue and know how to fix it? It is really annoying - I have to put my hand up to force it to stop coming down whenever I need to get into the rear hatch area.

See linked video. It now does this every time (I activated the hatch to open both times using the remote).

Try resetting the height to a little lower than it is now by holding the liftgate before it reaches its limit, and then hold the liftgate button on the underside of the liftgate for 2 seconds until you hear a tone. While this will reset the height limit of the liftgate to where you are hoilding it (reset it again to set a different height), it may show if there is a limit being exceeded when it is opening, forcing it to close. Maybe it will work if you set the height to just a tad lower than it is opening to now.

Yeah I had already thought of that. Didn't work. I even tried setting it to halfway up and the behavior was the same.

Notice in the video that when the liftgate gets to the top it dips down a little bit? It was doing that even when I set it to halfway. Wonder if that dip is triggering it to close.

Not on a Tesla but a GMC Acadia. It was an adjustment on the full open contact. Once it passed the max position it started down then would close. Try adjusting it down some by holding the close button before it get completely open.
