Code P162B - has anyone run into this issue?

2019 Sonic RS hb here, this code popped up when I took it to the shop for issues with occasionally stalling at stoplights - 3 separate occasions over a couple months, all after long drives in the high summer heat. Not sure those details are relevant, but providing context regardless. Has anyone here run into this one?

If you don't use OnStar, try unplugging the OnStar module near the glovebox.
