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
