I don’t think you can allow yourself to think that way as a company. Fussy debates about whose fault it was – when your customers didn’t do anything outrageously unusual – lead nowhere, just to bad PR.
They did something outrageously stupid. No conventional car should be left sitting for months at a time without appropriate preparatory steps, and neither should an EV unless it's connected to power.
The EV actually has a distinct advantage here -- all you really have to do is plug in a power cord. A conventional car has several much more involved steps to be taken.
