My inside door handle apparently has come loose everytime you close the drivers door. Also the sunroof keeps acting up when open and then trying to close. It will almost close and reopen to halfway. I was shown a simple fix for the later but must have forgotten. Because can't get the problem resolved on my own. Finally the gas cap cable has snapped and will no longer hold the cap from falling when pumping gas
