My Hummer is completely dead

[Eman32708]

My Hummer is completely dead. It was fine yesterday and had over a 50% charge. Do you think it’s the main battery or the small one?

I would check the small one if you can get access to it. Let us know what the issue turns out to be.

Mine also completely turned off, have you found out the reason?
