> I thought one of the selling points of electric cars was reliability over an ICE engine.

They are if you take car of them. Hertz notoriously did not have chargers in their lots and I've read plenty of stories of EV renters getting an EV with 20% of the battery.

If they are letting the cars sit and discharge to 0, yeah, that will look like them being "unreliable" and will ultimately wear the battery.
