The crazy thing is that all the dash and electronics worked fine since they are powered by the 12V system. It is just that Kia programmed the parking brake to automatically engage when the car powered off and it won't disengage the parking brake until the "drive system" is powered on. It just ignored the switch to disengage the parking brake. I had the 12V battery in my 2016 Kia Soul EV die and I had to jump it to get the car to engage the contactor so the DC-DC converter would engage. I always felt there should have been a temporary override button where if the 12V battery died the button could be pressed and it would engage the DC-DC converter for 30 seconds, long enough to get in and turn on the car. On the Niro EVs the battery is checked by the system periodically and it is supposed to be topped up automatically. Question is, how bad does the 12V battery have to get before the car notifies me that it is getting weak? -- David D.
