What a great forum! My 2018 Sierra Denali has been experiencing these issues for some time, but it's been so intermittent I've been afraid if I take it in, they won't find anything and look at me like I'm some crazy lady LOL I lost the steering twice the other night, fortunately while going slow, AND the truck totally shut down (vs shut off) as I pulled into a parking space. She's going in Wed and I'm going to mention this G218 and the negative battery cable for them to look at. It's still under warranty, so crossing everything that fixes it!
