An orange warning light showed up this week. The manual said something about “Propulsion System Failure.” Initially, the light came on intermittently and now it is constantly lit. The service dept said they can not look at the vehicle until next week. Also, my vehicle has not been charging to 80% the last two days.

Any advice would be appreciated!

Thats the “check engine light” basically. Needs diagnostic but if it wont go past 80% possibly module issue in battery pack

The vehicle ended up staying at the dealership service center for a week. The technician communicated back and forth with engineers at GM corporate and no issues were found. They reset the light and were able to charge and drive the vehicle normally again. My fingers are crossed that the light does not come on again.
