I got "check Hybrid System" error with all sensors are yellow on the dashboard of my 2011 Prius with 80k odometer reading. Currently no Hybrid system, only petrol engine works. Toyota is telling that it will cost about $3000 for parts only. Google search suggests that this is a common problem. Do you anybody had/have this problem?
welcome! can you find a salvage part and a local mech? it's a simple job. or, you might try calling toyota customer service and asking for financial help, since the car is so new.
