2017 Duramax and this has been going on for a year. The dealership keeps sending it back to me saying can’t figure it out. So I need your help. I am not trailering anything. Help.

Very strange. Is it throwing any codes? Code readers are fairly cheap for basic units.

I have no clue. I inherited my husbands truck and now what to drive it into a swamp. GM has been no help at all. The warning is not happening all the time. I’m going to weird the executive staff at GM and see if they can figure it out. As you can see I’m upset
