Possible multipro tailgate issue

[wizard4878]

So I hope this was a one time thing but...

While pulling my trailer my tailgate decided to go down on its own,  those of you who have pulled trailers already now that the gate will hit the handle for the stand.  The worse part is I didnt know that it went down so I not only have a dent in the inner/top gate it also has marks about 6 inches long extending outward from the dent where the handle rubbed side to side when I turned. 

The gate went down one other time when the truck was sitting in the driveway and I just assumed that I must have hit the button on the key  fob while it was in my pocket but now I'm thinking maybe not...

Has anyone else had their gate open on its own,  or am I the lucky winner?

Damn that sucks. Maybe it’s not fully latching or only latching one side? Dealer can scan for codes if it’s electrical issue.

Brainstorming...do you have the doors set to lock when you drive away?  Not sure that locks the tailgate but might be worth a shot testing.

That does not solve the problem.

I put a switch on mine, when I tow a trailer the tailgate and midgate is inoperative. 

Cost $3 and 15 minutes of my 13 y/o Son's  time.
