Hot weather charging/EA hot cord fault

I had parked my 2019 bolt in Mesa for about ten days while I was traveling. Got to the car around midnight, 102 degrees still. High for the day was around 117. Drove 4 miles to the ea charger and spent about twenty minutes trying to start a charge.

Initially the app wasn’t recognizing that my car was plugged in, when it did the charger kicked me off after initiating the charge. After moving to a different charger it initiated a charge and kicked me off again with a ‘charge cord temp’ error. Eventually, turning off the car and swiping the credit card a few more times allowed me to charge.

I was charging from 24% according to the station on a 150kw charger. Peak rate was 48kw on the charger and about 38kw displayed on the dash with and without the ac running in the cabin.

I was wondering if anyone else had seen this behavior at a charging station especially given the heatwave right now. I figure the coolant inside the cord was too hot and initiating the charge a few times allowed it to circulate around the system a little.

I live in AZ where the high is around 105-110 most days now. I went to an EVgo charger and it didn't charge at first but once I got it to start charging the car was only pulling 30 kw from the charger. The car was at 9% when I made it to the charger. The heat really does seem to affect charging performance not only from the car but from the charger itself. Also I have noticed that my range has been plummeting ever since it started getting hot as I am only getting 130 miles per charge now.
