I can't speak for the thread starter, but I received the "Low propulsion power" warning and check engine light this past weekend. After researching these threads and checking the codes, this does point to the possible ERG valve issue (bad or dirty). This also blows the F03 fuse under the hood. The fuse is named the "Non Walk Home" fuse
It is even labeled this on the fuse panel cover. Been running fine on Battery since, taking to Chevy dealer tomorrow. I've been keeping a close eye out for the Shift to park, BECM and the ERG valve as they are common issues for the 2017's. Looks like the ERG is first. I have 29K miles, with 7k ICE miles. I received the error when running on ICE, i noticed the coolant temp jump from 220 to 250, then the errors appeared.
I've read you can replace the fuse, unplug the ERG valve and still run the car if needed while waiting on parts if needed. Either way, I'll find out tomorrow what my situation is.
