I don't want to jinx it but they replaced my onboard charger and things seem to be working fine now. What a long strange trip it's been.
Well I jinxed it, this morning I tried to pre-condition and noticed it wasn't charging even though it was plugged in. Threw a P0D22 code. Then I tried to unplug and plug it back in and bam, P0AF8 again.I don't want to jinx it but they replaced my onboard charger and things seem to be working fine now.

Yeah I think at this point it must be something with a section of the battery or maybe one of the BCMs. We'll see what the dealer decides to do next.See this thread: http://gm-volt.com/forum/showthread...e-Car-Advice-Sought&highlight=cooperthebeagle
Sounds similar to what I experienced. Let me know if you have questions.
I had the software updated at the beginning of my saga which was included with the Voltec warranty. Another dealer tried to make me pay for the upgrade a second time, but I had my previous invoice so they were able to look it up and indeed it was covered. If you need a copy of my invoice to show them I can e-mail it to you. It is *definitely* included in the Voltec warranty.I feel used and abused again by the Chevy dealer. Out of the blue the car would not charge, giving the old "Service High Voltage Charging" message. I wasn't concerned because I have less than 100K miles, and of course we have the 100K Voltec warranty (of which charging is included).
The dealer said they had to "upgrade the software" at a fee of $250 +tax. Reading below I see others have corrected similar issues by re-booting (disconnecting the 12V battery). Dealer made no attempt at anything else but the one thing (they claim) they could charge for.
1.) Has GM built in a time bomb so the car would not work after some predetermined time or when a software upgrade is available (as the dealer is implying) necessitating a mandatory upgrade?
2.) Why do we have to pay to have software upgraded, especially during the warranty period? Isn't $45K enough to pay for a working car?
3.) Could they have fixed the issue rather than upgrading the software? It worked just fine before the upgrade until something happened they should have repaired.
