Today I was at the Ford dealer and I pluged my 2018 smart car into the Fords electric station ...its a full charging terminal fir all electrics . It fit my cars plug. After about 10 minutes my cars dashboard started blinking red light which at that point it stopped charging. . It also indicated that I need to call in to the workshop right away. I was getting ready to call AAA to have IT towed to the Mercedes dealer when all of a sudden the car started working again. My question is the blinking RED light at the plug point of the car, then the car started working fine. I recharged later with a full charge.
