My 2016 is doing the same all power is lost as I slowly turn steering wheel truck erratically shuts off and back on. I hope this is a recall due too how dangerous it could be in traffic. GM please notice this issue.
My High Country has periodically has issues, I believe in the steering column.
While driving in a parking lot a sudden shutdown all dash and electrical equipment. Flashed parking assistance and truck dies or blinks off then back running.
Anyone have an idea whats going on.
