Coolant alert and dirty gearbox oil are my concerns for KIA reliability. We own a '22 Niro EV. Flushing the coolant will trigger alert that can not be fixed? Hilarious.
In a lot of ways I know Tesla has ironed out some of their issues and don't have much in the way of maintenance (and things like coolant are much cheaper to replace than they are with Kia)- but I worry about other issues with them, like the control arm issues that seemingly are a problem with the Model 3 (and Model Y).... so I think the grass is not always greener on the other side.
