Reddit r/Ioniq: "Ioniq 12v battery died after making a 4hr round trip.". Just bought it approx 5 months ago. After my trip I plugged it up and the next morning the car wouldnt start. App said it wasn't charging but I chalked it up to an app error. It wasn't lying! Is this just a simple 12v change, or will I need to worry about using my warranty?
