Call OnStar and ask them to give you the codes it was throwing.

A few Hummers have had issues with "hybrid battery system" I wonder if they are still working out the kinks on the wireless communication between modules.

I would have liked to know the codes it is throwing.... @JackBurton you can call Onstar and request the codes.

I'd take that in, check if there are any firmware updates and have them check the coolant levels...

Got to remember the Hummer is the first truck with a wireless BMS... 24 of them. So it might be a firmware issue where it doesn't get as strong a signal as it expects and tosses errors.
Something that will be refined over time.
