    Yesterday I started getting messy electrical issues in my Prius. All symptoms happens mostly in random. One time I get almost all dash lights on, other time I get left turn signal on everytime when I press the brake pedal. Also when car is turned off, the stop lights keeps on. Strange things happening. Any ideas?

    Check for rodent damage on all wiring harnesses that could affect the systems/lights acting weird.

    While it probably is not the cause of that mess.........
    One should not overlook the obvious and check the 12 V battery and it's main connections, at both ends, first.
    Might want to check the charging voltage too.
