I was charging the other day at a Level 2 public charger and onstar notified me that the charger stopped charging and to check the vehicle. I got in the car and pressed start to see the kilawatts charging and it would fluctuate between 0 and 0.5 kw. The car was at 80%. I unplugged the cord and then plugged it back in at then it said 7 kw, after about 5 mins I got the text from onstar again saying the charging stopped. Checking it a second time it said 0 and 0.5 kw. Anyone else experiencing this issue?
