Why want my hatch not shut?

without being there, it is hard to say. Can you at least drive over to the Subaru dealer and have them look at it?

Try recycling the system: FULLY open the hatch manually until the very top. Then FULLY close the hatch until you hear a double-click as it latches and locks. THEN push either the dash button or the hatch button and it should work. If not, chase Subie for a free latch assy under warranty.

Ok the answer is, per service rep at dealer: Background - I could manually open and shut the hatch but the latch at the bottom would not engage. None of the buttons for the latch worked, just a beep when pressed. You could press down all you wanted on the hatch but it would not work. Solution - while the hatch was down, Hold the button under the Subaru emblem for 10 seconds. This was a hard reset and after that the hatch worked as normal. Easy, no worries.

I had occasion to use this dealer's solution and it worked. Thank you.
