    I have a 2009 Prius. Last week I got the red triangle of death. Everything seemed to be running fine and the next day it went off and stayed off for a few more days then came on again while driving to work. The car began.turning off & on, & the brakes were pulling really hard to the right. I was able to pull to the shoulder & the car shut off & wouldn't start. I had the car towed home & got on the internet. Lots of things pointed to the 12 volt battery so we had it tested & it was bad. Bought a new one & everything seemed fine for 4 days & suddenly the death triangle was back. I took it to an auto parts store to get some codes & they gave me 5, PA0903, C0200, C0205, C1241 & C1310. Does anyone know what might be going on with my car & what I can do to fix it? I can't afford to take it to a dealer. This is the only car we have for a 3 adult household so hoping for a quick answer. Thanks in advance for any ideas or suggestions.

    Welcome to PriusChat !!

    Please check the first code again, most likely you meant P0A93. Sounds like you have a failed inverter pump, which is an easy fix.

    The car will start and run until the inverter overheats, shutting the vehicle off. Once it cools enough it will start again, like in the morning. Though it can be moved around, don't drive the car hard, fast, or during elevated temperatures (over 70F). Best not to drive it at all until whatever problem is solved.

    Focus on DTC P0A93 first, then later on the C codes if needed.

    Check the inverter coolant level and the inverter pump for operation, if you can't hear the pump or visually discern liquid movement, then take a finger or a pencil/stick/rod and touch the inverter pump housing to sense any working vibration : P0a93 engine code | PriusChat

    Here is the workup for DTC P0A93 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/repair%20manual/04pruisr/05/21bpm/0a93346.pdf

    Thank you so much for your reply it was very helpful. And yes you are correct regarding the code - oops! What you said about the inverter overheating makes perfect sense as to what has happened. We will be buying a inverter pump and a friend of a friend is a mechanic and will be replacing it for us on Monday. Fingers crossed! :) Will let you know if it works.
