Is anyone having trouble getting the tailgate to consistently open using the foot-kick movement? Our success rate is less than 20%. Note that we have the trailer hitch installed - I'm not sure if that somehow plays into it. We've tried everything that we can think of - slow kicks, fast kicks, kicks in a sweeping motion, kicks closer to and farther from the bumper sensors. Nothing seems to consistently work. The key fob is always in one of our pockets. We haven't checked with the dealer yet but that is our next step if no one here has a suggestion.
