    Hello,

    When I am driving my dash board lights will flicker and dim and brighten on their own.

    I checked the 12v battery, and it shouldn't be that - was 12.4v.

    Not sure if may be related, but there were also two times I was pressing the gas, but not really seeming to be able to increase my speed.

    I have NO warning lights ....

    2006 Prius - 160k - hybrid battery replaced about 10k miles ago.

    HELP!

    I just started experiencing flickering of the dash and message center. Everything flickered off and on real quick a couple times.

    check the 12v to start with. after that, it gets difficult.

    It would be REALLY nice if some of the people who reported this problem MORE THAN A YEAR AGO would come back and report the outcome for the benefit of others.

    Seems like the overall number of considerate people keeps going down all the time. :(

    There have been similar discussions in the past.
    The "usual suspect" is a main 12 V battery cable that is loose or corroded.
    The next suspect is the battery itself; there can be bad connections INSIDE the battery.

    After that, a lot of things could cause an intermittent loss of power.
