Multiple Volta charging stations refused to start and one ChargePoint that I had used before did also. At first I thought it was dirty plug handle contact pins and latch, so cleaned everything up and tried it in my garage at 8 amps on a 110. That charged fine. Never had any problem until a dealer did the main battery recall upgrade. Car was returned to me with a full charge and working perfectly, but the first time I tried a free Volta charge station the Bolt displayed "Charge Not started". No other info was displayed. I looked through the menu displays and cannot find any info or settings that would have this effect.
