Hyundai has a service bulletin for their 12V battery but isnt notifying owners. Today my vehicle stopped working and lost all acceleration on a busy 3 lane street that is 55mph. I was able to limp it to a left turn lane where I had to research the issue and found many others had instances like mine. The battery stops working and subsequently stops the vehicle from accelerating and tells you to stop safely with no warning or indication that youre about to stop moving on a road.
