Sometimes everything works just fine and it will both open and close by buttons on door and by key fob.

But more than not, it will open fine but it does not respond to the close button or the double click on key fob to close. I end up 19 out of 20 having to manually pull don’t and lock the list gate myself.

Has anyone had this issue or have seen a thread on this closing issue ?

Is there a way to reset the signals on the lift gate? Randomly it works fine.

It’s the actuator which has 6 different internal switches. You could replace it for under $250. When I was trying to find out myself I went and purchased a non-OEM from autozone. When I knew it worked I returned it and ordered a OEM one which is better. My autozone non OEM failed in 3 weeks.
