Still no fix for this? Com'on GM. Makes me not want to upgrade to a new GM truck when I trade this one in soon...
Having same issues with my '15 Silverado, but the most worrisome aren't listed enough so I'm emphasizing them... The damn truck dies (briefly) running down the highway when I use my turn signal and dies or almost dies when I make slow moving turns (i.e. in parking lots, driveways, etc). Also notice headlights dim a lot when experiencing this behavior.
Been struggling with this for the better part of a year. Very intermittent, sometimes I've gone months with no issue, sometimes, it happens multiple times in one day.
For me, the most likely explanation seems to be some kind of wiring issue or battery terminal connections. The last 3 or 4 times I have had immediate success after popping the hood, knocking hard a few times on the plastic housing mounted on top of my battery, then slamming my hood shut. As a bonus, it's also a nice way to relieve some of the frustration from the situation. Hopefully this helps save someone from wasting money on a new battery or tow!
