I have recently started getting issues charging. This time I finally was able to check it car and charging cord both were red (flashing I think). This is my original charging cord and my home charger (with a dryer plug charges at 31mph). On screen in car it said "Charing Equipment reports error" CP_a057 above that. Recently my power went out from a tree over my above ground line from my house to the street it was ABOUT that time I started getting this issue - maybe. Most times opening the app starts it again before I can even get in the car to see the error. I unplugged cord from car and wall and plugged both back in and it charged fine.
