    Was driving on highway. Hit gas to pass,. Sudden loss of power.. Red Triangle, and ABS , VSC, Check Engine light all on. Gas engine does not start. BUT the car moves electrically.. fortunately the hybrid battery was mostly full.
    Any suggestions.. Tech stream did not show any sub codes I don't thing.. not that I saw. Clicked on everything I could.. got some freeze frame data or live data. But that's it.
    Any suggestions on things to check before just replacing the Inverter Converter?

    Gas is almost as important as cookies!

    I see 6 dots on the fuel gauge...
    the subcode will be in the freezeframe data screen
    that sure is a lot of codes, would hate for you to start swapping out an inverter just to find out it doesn't solve the problem.

    Are all of these new or previously existing?
    Brake codes
    Communication loss codes
    Air bag codes
    Not too worried about the C2122 since the black tape explains that one :D
    All over the place but what do they have in common?

    Did you click on the snowflake icons:whistle:?

    Sounds like an inverter pump to me;).

    But confirm with the INF codes present on the freeze frame screen(y).
