Even though Christmas is coming up, I’m not enjoying the light show my ‘19 Equinox is giving me. Last week, the “check engine” light came on. A day later it went off and hasn’t come back. This morning I got an “AWD OFF” light (I hadn’t turned it on) and then it went off. Then a “Service ESC” warning came up, as well as the ESC light with the line through it. What’s going on here?

 

Something electrical no doubt.

 

And now those lights have gone off too.

 

Have you scanned it for codes?
Don't do anything until you've scanned it with a good scanner.
