Trying to figure this one out. We checked into a hotel in yosemite but the room wasn't ready. I got some stuff out of the cargo area and we left for almost 3 hours. Couldn't believe it when we came back but the liftgate was wide open. I am positive that I closed it and watched it latch because I wanted to make sure the suitcases weren't in the way. Thankfully nothing was stolen. All our clothes iPads etc. we're still there. I am stumped as to what could have happened. Only two things I can come up with either I reached into my pocket walking away and somehow hit the button twice or another key activated it. Don't know how many different frequencies they use. Anyone ever heard of this or any other thoughts?
