Hummer EV Charging Issue

[henry954]

Hey guys!
I’m having a bit of a headache with my Hummer EV. I plugged it in overnight, expecting a full charge, but it decided to quit early and now it won’t charge at all. Plus, the check engine light is shining bright. I took it to the dealer, and they pulled some codes, but I have to go back next week.

Has anyone else dealt with this? Any ideas? And do you think that crazy downpour I drove through last week could’ve messed things up? What do you guys think?

Just a week after I got my ride, I ran into a similar mess. Took it to the dealer, and they sent me on a wild goose chase to another spot because their lift was too small for my beast. Now they’re swapping out the battery, and I’ve been stuck without wheels for almost three weeks! It feels like they’ve had it longer than I ever did! So beyond frustrating! Ugh!

So I’m back!

Just wanted to drop a quick update. I decided to do a hard reset by disconnecting the ground on the 12v battery for about 30 minutes - yep, that’s a thing! After plugging it back in, I followed the prompts to tweak the windows and then took a quick ten-minute spin. No check engine light!

Now that I’m back home, the L2 charger is working like a charm. Thank goodness!!

Oh, that’s awesome news! I had no idea a hard reset could work wonders like that. Glad to hear your charger’s back in action! Enjoy!
