I get this same issue on my 2019. I notice it happens when I leave my hazards on (I do this frequently as I'm a technician working out and about). In addition, I normally keep my high speed charger plugged into the 12v outlet. Once the check engine light comes on, I drive normally. After a few shutdown and restarts, the light goes away.
Chevy should really find an alternative light for such a stupid issue. This never happened in either of my Tacomas. Back to the Tundra after this Chevy... First and last.
