The only thing that concerns me is that when I was hit the car randomly shut off. Is that a safety feature? If so that will make me feel a lot better since there really is no explanation why it shut off because I was hit in the back.

Automatic fuel pump shutoff. It is indeed a safety feature designed to keep the street from getting flooded with gasoline should a fuel line break during a collision. Your fuel pump will also be shut off if the oil pressure ever drops below a pre-determined level for too long.

I don't know if GM has ever done it, but I know that Ford in the past (and maybe currently) used to put a fuel pump reset switch in the trunk, and then hide the reference to it in an obscure part of the manual.
