Oh, man. My 2014 Sierra has been doing this for two years seemingly at random. Had no idea what was causing it or where to begin looking. Dealer could not duplicate it, and concluded it was a bad battery connection. Cleaning the battery posts seemed to fix it for six months or so, but then it started again late spring (when the weather in Atlanta started getting hot), and when I cleaned the battery this time it didn't fix it. This has been driving me crazy! And yes, I fear for my safety after almost hitting the brick wall in my office parking lot. Thank god for me it only seems to happen at crawl speeds, usually when I'm turning into a parking spot, but the danger is real. When I asked the service rep if he had ever heard of this happening on other trucks he said no, but he had a funny look on his face when he said it. So, before I found this thread, I was looking at the Recalls on the GM web site (if you log in with your VIN it shows you all the recalls for your vehicle) and I saw the June 2017 recall #17276 Loss of Steering Assist. I assume this is the same issue? I don't know, but this week I took it in and had them do the recall. Incidentally, I never got any kind of notice for the recall. I found it myself on the web site. The invoice says: "reprogrammed the power steering control module labor op 9102922". I hope that fixes it, but if it doesn't then I will take up the dash and clear the ground as explained in this thread. I may do that anyway. Thank you so much for posting this information. I can't believe it took them so long to do a recall, and I'm still not sure if the recall is for the same issue since it doesn't seem like they did anything to the ground. If anyone has any additional information please share.
