Service it : ask Playstation to send you a box and they will fic your PS3 up. If it's still on the one year warranty, it will be free. If not, you will throw bucks away.

Well does somebody has the same issue? I'm always aiming and I can't do anything except shooting when I'm on foot. My controller is used but I can still use the gas and brake button. It's not a jam of some controller button. I'm just always aiming when I'm on foot. Any ideas?
