NHTSA Complaint #11588671 — 2019 KIA NIRO EV

- While driving, we received a notice on the dashboard to "stop driving and check regenerative brakes". Simultaneously we lose 95% of our braking power and all of the acceleration. Slamming on the brakes all the way to the floor provided some minor braking ability, but it was significantly diminished and frankly terrifying. We turn the car off, turn it back on again, and everything seems totally normal. - We cannot recreate the error, but we call the dealership. They say they can get us in in a week to service us. As this is our only car we keep driving it cautiously. - This happens again once more, before we bring it into the dealership. - The dealership runs a bunch of tests, tells us its the 12V battery, replaces the 12V battery, charges us $500 and tells us its fixed. - one week later (today) the same thing happens. Clearly it's not fixed, but even if it had been fixed, why is so much of the braking tied to the 12V? The dealership cannot get us in for days and is suggesting this may not be covered under our warranty.
