Same problem. First the light stays on but closing the tailgate a few times with a firm hand push usually turn it off. Now the tailgate doesn't lock when using the remote key, just the 4 doors. The anti-theft does not get activated since it detects the tailgate is still unlock. There's a small black colour plastic box with electric wires connected to it inside the tailgate (not sure the name for it). It has mechanical connections to the locking latch. This box still makes some noise when remote is pressed but that's all it will do. Using the key to lock the tailgate and this will activate anti-theft. Removing and re-installing the interior tailgate panel to access the bits is just as painful as paying your dentist an unscheduled visit. Anyone knows of a DIY way of getting the tailgate back to it's original operation with the remote?
