They almost exclusively bought Teslas and Polestars and are now complaining about maintenance costs? I remember a few years ago, the first time Tesla wasn't on the very bottom of the JD Powers Initial Build Quality list the editors put up a special note that it wasn't because Tesla had gotten better, only because Polestar was even worse.
Seems like Hertz's main problem is common sense.
I'd really like to rent a Hyundai Ionic 5 for a road trip next summer but I can't find anyone local that rents any electrics other than Teslas.
