Yes. GMC vehicles have had official Supercharger access since September 2024. You charge at any Supercharger marked “open to non-Tesla” using the Tesla app.
The 2025 Sierra EV has a CCS1 port. At NACS stalls you need a NACS-to-CCS1 DC adapter: the GM NACS DC Adapter (85836744) ($275). Same GM adapter; also sold through GMC accessories. Adapter details. Magic Dock sites (green) need no adapter at all.
At the stall: the 2025 charge port is driver-side front. Pull in nose first and close to the post. You will often end up using the post to your left; Tesla says that is acceptable when the site is not busy. Expect about 174 kW at a V3 stall, well under the car's 350 kW peak, because the 800 V pack has to boost from 400 V. V4 sites rated above 250 kW remove that limit. Silverado EV twin: expect about 174 kW peak on V3 Superchargers.
How to charge: download the Tesla app, choose “Charge Your Non-Tesla”, add a payment card, pick the site and stall number, plug in, then tap Start. Older V2 Superchargers (grey on the map) only work with Teslas.
