Literally from the linked article: "Hyundai and Kia have the same parent company, however the Kia Niro EV has completely different batteries on board—sourced by a different South Korea–based supplier...". So nothing about Kia's having a recall.
Also Tesla's have caught fire. It's a risk with all EV's.
I believe that is the same battery manufacturing issue that caused GM to recall all Chevy Bolts over potential fire concerns. (only a tiny number of cars have actually caught fire). This was finally traced down to problems with a specific manufacturing problem in batteries supplied by LG who supplied those batteries to GM and Kia and another manufacturer.
I don’t remember Tesla recalling all their EVs for fire concerns.
