What a flat 12-volt looks like.

What we see
One thing to know about the GMC.
Hummer EV tires and weight mean a plug-patch is often the only sensible roadside fix. A compact spare does not exist for that vehicle.
Port locations describe typical US-market versions. Confirm with your owner’s manual and tell dispatch your exact model and year.
GMC questions
Straight answers.
Can you charge a GMC?
Yes. The connector is CCS1. We carry Tesla (NACS) and CCS1 connectors, and CHAdeMO is available on request.
Where is the charge port on a GMC?
Typically the driver-side front fender on the Hummer EV and Sierra EV. Ports can change by model year, so confirm with your owner’s manual and tell dispatch your exact model.
Can you jump-start a GMC?
Yes, a jump-start only ever involves the 12-volt auxiliary battery, never the high-voltage pack. On these cars it is a 12-volt battery under the hood with conventional terminals.
