Ultium12V or your ultium batteries???
there have been more than a few 12V issues already
I doubt it actually has a short, otherwise your Hummer would be burned to the ground. More likely an open circuit somewhere, or some degraded cells.Anyone with a bad battery yet? Apparently mine has a short and is being replaced
Wow...that's not a good look to have issues already.Ultium

Thats basically same as a check engine light, could mean a million things. GM and TAC move slow with all the moving parts. They will send out an Engineer to do a few data dumps then finally allow the technician to work on it. Mine took 20 days approved for me to diagnose and to get a coolant heater module replaced when it was all said and done. GM just really wants to ensure they dont miss something that could possibly be a reason for failure that may help improve the product. Hopefully your vehicle gets fixed quickly.Mine is currently at the dealer service with a "Service high voltage system" message. open case with TAC but it has already been a few days. Everything works as usual but the message concerned me.
