    Our 2005 Prius had hybrid batteries replaced in 2014. In 2016 it turned over to 299,999 miles. Since then we have gotten about another 75K out of it. Last night it died. Had to have it towed home. When we press the start button, we get a dash display of several green rectangles. Any wisdom on this? Did hybrids die again? Husband said lots of lights came on as he coasted it down off the freeway and parked it after the engine died. But he doesn't remember what all they looked like, except red triangle. We have a Verizon Hum on it, but didn't get an alert from Hum. Thanks for any guidance.

    I've seen the green rectangles when the 12v battery is extremely weak. It may be worth checking that. The rectangles are actually the outlines of the gear position indication. It would be unusual for that to happen while driving though, since the inverter is powering the 12v system at that point..

    If you walk up to the car and look inside, is there one blinking red light on the dash?
    If you open the door, does the door ajar light come on?
    If you get in the car, with your foot off the brake, press the power button one time, what happens? (mfd and radio should come alive)
    Press it again...what happens? (dash should come alive)
    Put your foot on the brake and press it again...what happens? (car should go "ready")

    Any chance it was run out of gas and then killed itself driving on the hybrid battery only? If the 12v battery is still good (and the power source ecu is still good), the dash should still turn on when you try to start the car (unless you have a combo meter failure, which is unlikely since you still had alarm lights).
