Infamous Stabilitrack, steering assist, traction control, etc. issue

[Chris Dems]

I have a 2017 Silverado with 51k miles. I’ve had sporadic issues with the dreaded Stabilitrack, steering assist, traction control, etc messages and the truck goes into limp mode. Last weekend was the 5th or 6th time it happened and this time it acted like the battery was dead, wouldn’t even turn over when trying to start it.

 

I’ve troubleshot the engine grounds, g218 ground and the other items on the GM bulletin for these symptoms. And still experience it randomly. Any other suggestions on how to figure this out? I hate to bring it to the dealer and pay their rate to blindly spend hours figuring it out.  Any thoughts on where to go next in troubleshooting and resolving this?

 

Here’s the GM bulletin. Much of the same fixes suggested online.

Hey Chris,

I have a 2014 Silverado LT 5.3 and was having the same issues. The way I got rid of the problem was by cleaning a grounding point that is on the chasis under the driver side. Once I unscrewed that ground, cleaned it with a wire brush until I saw metal and reattached it all issues went away. I had tried that g218 ground but it did not work for me. Let me know how that goes. That is what worked for me and it’s been about 1.5 years and haven’t had that issue.
