The rear driver side door lock will not lock. The child safety lock doesn't even make it work. All other doors work with the remote entry key fob and alarm activates but the rear passenger door remains unlocked. I can not even lock it manually. I fear my grandchildren will be able to simply open the door and exit the car and am very concerned for their safety not to mention the possiblity of someone entering the car to do harm or vandelize the vehicle.
