Sunday, June 25, when I was driving the car on the road, the engine shut off and the car stopped running. 3 warning lights show on screen: engine light; 48v Battery Service Required; 12v Battery service required. I used the break to park the car on the roadside after that. I tried many times to restart the car, Waited over one hour and 40 minutes it finally started again, the engine warning light was still on until the second day morning, and I was able to take pics as evident. 1.
