Left for work 1/4 mile, message appears "Turn vehicle off and check Hybrid engine." Pulled into a quick stop place, turned off car. Came back turned back on, within 2 miles message came on again, this time the engine light came on and has stayed on. Pulled off road, turned off again, but when turned back on, engine light stayed on. As I got to work message came on again, along with the "traction control" light. Called Dealership,(this was Saturday 11-27). Tech responsible for Hybrid repairs won't be in until Tuesday. Now it's a waiting game....TO BE CONTINUED......
