Hertz has become known for broken systems that don’t track their cars properly. It seems that just because a vehicle is returned, and gets re-rented, that doesn’t mean Hertz knows it ever came back. And though they claim otherwise, they seem to have a hair trigger for reporting cars stolen (or at least threatening customers that they will).
The rental giant argues that this is rare (a small percentage of total rentals) and a thing of the past (they’ve made process improvements). But it seems to keep happening. And though it may represent a small portion of transactions, readers of this blog keep reporting that it happens to them.
