    Hi everyone
    I was driving my Prius 2 last night and the red triangle, vsc, and circled exclamation point warning lights came on. Was able to drive it 50 miles back home with no issue.
    Took it to a Japanese specialty mechanic and they read the codes and told me it was a drive motor inverter cooler issue.
    However, since then the red triangle and other warning lights have all turned off. Car is running fine and hybrid system is functioning. Do I need repairs or am I good to go?
    Thanks

    If you want a reliable car in all circumstances, then yes, replace the inverter coolant pump with a new OEM pump.

    The pump is known to fail after 80,000 to 100,000 miles.
