Hyundai/Kia do have 5/6 years of making really decent EVs in their locker though. But this is a new all EV only platform granted.
In case you missed it, almost all of those really decent EVs has had at least one recall notice issued for various defects related to the battery charging, regenerative braking and even the supplied granny chargers so it's not like they've not had issues already. Some cars (2018 Konas) have had 5 recall notices issued. My car (built May 2020) has only had one - for an issue with the ABS and regenerative braking. But at that one, they replaced the granny charger with a more 'bounce-resistant, droppable' one which other cars were recalled for.
