I've only had our car 3 days now, but there have already been several times when I've gotten out of the car to get something out of the back, but the tailgate won't open until I go back to my driver door and press unlock. This happens whether the key is still in the car in my purse or if I have it with me. If I walk up to my locked car, I can open it just fine, but not if I've just opened the driver door and gotten out. It's super annoying! Is there a setting I'm missing that would solve this, or something I'm doing wrong? Thanks!
