We purchased a 2019 Bolt LT about 3 weeks ago. It's an adjustment in many ways, but my entire family seems to love this car. Soon after we bought it I tried using a ChargePoint DC fast charger but I could not get it to work. The charger kept reporting Fault Code 87, and the Bolt reported "Unable to Charge" on the dash. I called customer support and spoke to someone who was very nice but clearly had no idea what this fault code meant or why the car wouldn't charge. She tried rebooting the station, but nothing worked. She escalated the support call and we gave up for the day. Soon afterward I tried a Greenlots fast charger and had a similar experience: the Bolt reported "Unable to Charge". A few days later I tried an EVgo fast charger and it worked. So it didn't appear to be an issue with the car.
I searched quite a bit for solutions to this problem but couldn't find anything that helped. After thinking about it a bit I realized that the EVgo charger had a long cord with lots of slack, while the ChargePoint and Greenlots chargers had short cords that were draped between the charger and the car. The cords are heavy, and this put a lot of lateral force on the plug in the Bolt, so much so that it was difficult to unplug the cord. To see if this could be the problem I returned to the ChargePoint station and parked right next to the charger (I had to park illegally to do this). I started a charging session, plugged it in and it started working immediately. I'll try a similar maneuver at the Greenlots charger and post an update.
Hopefully this helps others who have reported this issue. If this is the problem then I'm afraid that some DC fast charging stations will be unusable for our car because the cords are too short.
