    I am not entirely sure which forum I fit into, my Prius currently has 176k miles on it and it’s a push to start up. About a week ago I’ve been having what it seems to be electrical trouble. It first started out with both my driver side and passenger side doors not being able to lock. I can hear the doors attempting to lock but with no success, then about a week ago I went to turn on my car like usual pressing the brake and then hitting the power button. All that came up was the power on screen with the check engine light and the battery light, but after trying for a few times I was able to get the car going as if nothing ever happened. This has continued to happen a few times since then and maybe completely unrelated now my audio is starting to skip when I play music from my phone. I appreciate any and all help!

    Probably a weak 12v battery.

    This is a ~$220 part at most Toyota dealers. Very difficult to get the right one anywhere else. Toyota will install it for you for a bit more if you want, but it's an easy job and you might do it yourself or have a cheaper neighborhood mechanic do it.

    I agree with Leadfoot. Most likely a failing 12v battery. If it's the original, at 8-9 years and 176k miles, you definitley got your money's worth out of it. Dealer can check the condition for you. I wouldn't wait too long to have it looked at. It may not get you through a NH winter.

    If you are they do it yourself kind of person in Automotive Incline gifted.

    I would skip the dealer it will charge you $150 + diagnosis fee Spend another $220 plus for the battery plus the labor to install the battery then the labor to clear the codes and the labor to test the system you will come out of the dealer with a $600 battery.
    That’s what happened to my ex-wife in her Prius when she went to the dealer here in San Francisco.

    Yeah, a lot of dealers will nickel and dime you to death. Guess I got lucky. Mine waived the diagnostic fee as long as I bought the battery. Not much you can do about the battery cost. I paid $212.00, but it's pretty much the same most places. Installation was $65.00. WIth having to dig under the rear seat, and also maintain the trickle charge to not lose the infotainment center settings, I was willing to pay that. But DIY wouldn't be that difficult if you have the tools.

    Me too.
    But yours is about the age where the door lock actuators are likely to fail too.
    Low battery voltage might make them act up a bit before a total failure.
