I am having this issue with my tailgate. It won’t release more than one out of about 50 tries. I have taken it apart and I see that the linkage system and electric actuator are a joke. With the cover off the side of the tailgate, I can release it every time, quite easily, if I grab the linkages and release them manually. Clearly there is an adjustment issue, or the switch actuator just doesn’t move far enough. The linkage hooks into plastic bushings and and has about a half inch of free play. If the play was not there, it would open fine…there seems to be a very obvious and bad design flaw in this electric release system.
