This is a first for me so please forgive me if I'm doing this wrong. I have a 2005 Jeep liberty sport and while backing out of a driveway today it suddenly came to a stop. It won't roll in drive, reverse or even neutral. It hasn't made any kind of sounds. It was actually really sudden. Does anyone know what could possibly have happened? This is so frustrating because I have 2 kids and I can't be without my vehicle.
