They replaced HPCM1 and all was good until I went to the same DCFC station a few weeks later and it died again and had to be towed again.

But I insisted they do a DCFC session before I pick it up and when they did it failed again.

This stupid story was because the local dealer has
to follow Chevy's 'Trouble Tree'.
Third guess on the tree was the one that fixed it, but I was stuck paying for the SDM which they claimed could not be put back on the shelf.
There was nothing wrong with my original SDM.
I put up a long
fight and got it reduced to $200,, but still....
Is this how it's done when a Bolt has an issue?
GM has to come up with a scientific method of Troubleshooting modern EV's and not an old fashioned 'Trouble Tree'.
This has to be fixed before I buy another EV from GM.
I doubt Tesla, Nissan, Kia, Hyundai use trouble trees to fix their EV's.
Used '14 2LT w/ DCFC. +69 K miles.
Mostly free charging! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 2nd guess not covered by warranty and cost $800. 3rd guess fixed the problem.
