    I have a Problem with my Prius 3 2010. Sometimes difficult start- Navigation vanish and Motor cannot be started so I have to use emergency start. Sometimes no Problem.
    I let it twice chek up in car Service but nothing was found. I was advised to buy a new battery but it is still good(also checked).
    Can anyone help me.
    There is a link to short video

    maybe a loose battery connection, check for cleanliness and tightness, especially negative to ground

    Yeah, is this the original battery? And with the car off it's reading 8.5 volts? It's time to replace.

    Thank you for your answer. I was by two toyota service stations for battery check. They said, they will not replace the battery, because it good is.
