If Hertz reports a car stolen because front desk staff made a mistake, that's simply not criminal. This also applies to you as an individual too. If you report your car stolen when you forgot where you parked it, that is also not criminal. Hertz is being treated the same as you would be.
I don't see anything in this story that describes a crime. (except for the people who may have actually stolen cars) These are descriptions of civil wrongdoings.
