2006 Prius (gen 2) 201,000 Miles Serviced by Toyota, never missed an oil change Orange County, Ca Last night after leaving a friends, about 1 min into my drive I got an explosion of dash lights, the car shut down and turned off. (12V battery is fine) Red Triangle, Check Engine, The works. Pulled over and ran the OBD Fusion app and came back with P0420 and P3190. Did my research, Cat or O2 sensors, etc. Got car towed home, decided to try again before going to bed and everything was fine, no dash lights. Re-ran the Diagnostics, and cleared the codes to see. SO far so good. Anyone else have this weird issue?
