Tank canonm/machine gun auto aim - uncontrollable

Having this exact issue on every single map.  First the game would rarely load(once in twenty or so attempts) now we finally get in and aiming the tank main gun or mg is terrible.  You try to aim at an enemy and the gun moves itself to a fence or top of a hill, anywhere but where the player wants to aim.  This is so frustrating and is the same in all found vehicles.  EA Please fix this useless the tank knows better than the player algorithm you have in this game that give so much frustration to players.
