    I have a 2007 Prius with 107k miles. Last July it had a minor drivers side front end collision. Last November it had the hybrid battery replaced. I believe all this is unrelated just putting it out there for information.

    I am currently having the red triangle pop up intermittently. When it does a "problem" message will display on the MFD. This seems to occur most often after a long downhill or when the Energy display is showing the hybrid battery is nearly full.

    The hybrid battery seems to be functioning normal and the car is driving normal and has expected fuel economy. I do have a headlight that cuts out occasionally but no other noticeable electrical problems. I do not have a diagnostic device to get the codes.

    Yep. You'll need the codes to help point you in the right direction.
    Otherwise it's just wild guessing.

    New hybrid battery was replaced at the local Toyota dealership.

    Statistically speaking, it is highly unlikely to be your battery.

    Again, code reading options in my signature. MiniVCI is the best option.
