I own an EV6 and I definitely feel like Kia/Hyundia, especially their EVs, is essentially a different company than the one putting out easily hotwired and unreliable cars from just a few years ago.
Story I heard, was that Hyundai hired away many high-end QA people from Toyota, and because there's no intellectual property treaties between Korea and Japan, there's really nothing Toyota could do about it.
They apparently even took plans, detailed documentation, endless amounts of information to Hyundai. I'm not sure of the veracity of that information, but it sure explains how Hyundai became incredibly good, literally overnight.
They used to be a joke.
As a counterpoint:
Telluride/Palisade causing fires because they cheaped out on the current/torque sensors in the drive motors for the seats.
ICCU failures across their current EV platforms. No fix planned last I heard.
It hurts me to point this out because I really, REALLY like where their cars are going. Their new van is EXACTLY what we want, and I'd love an Ioniq 5N.
But those failures are critical and speak to a very deep engineering culture issue.
