    Hello, mechanics of Reddit! Today is a scorching 90 degrees and a few car lights on my dash turned on (Pictures included). These lights appeared as I waited at a train and had a long line for a pharmacy drive thru. The battery on the center console keeps fluctuating in charge and the fan kicks on in the back (I believe that's for the battery). This said, I just replaced that battery not too long ago, and I was curious if it needs to be replaced again or is it the heat? Could the problem be something else? Whatever it might be, I hope to have an answer because these lights worry me! Thank you for your time :)
    Edit: Car started having difficulties accelerating as I got home

    With all the warning lights on the dash, you will have trouble codes that need to be read with a gen2 compatible scanner. Retrieving the trouble codes will tell you how to proceed with troubleshooting the problem(s). That being said, everything that you have described points to a problem with the HV battery.

    Reddit is social media @bisco It's something the kids do to get answers to questions, as well as to bully their friends and foes...

    Welcome to PriusChat!!
    It may not solve your issue, but when was the last time you inspected or cleaned the HV battery fan?

    FYI : you're moderated until you've posted 5 times.
