    Stopped at ATM when heard a thump under seat and all the above appeared on control panel. Waiting on computer code reader to test vehicle. Any clues to what all this means. Vehicle 2006 with 101K. Recent service as scheduled with coolant and inverter coolant and belt replacement done. No other issues to date with vehicle.

    Thump under seat is a new one.

    How old is the 12 volt battery in the trunk?. Not the Hybrid battery but the little 12 volter? Ever had to be jump started?

    Welcome by the way.

    The 12 volt battery was replaced two months ago

    Did you get the hybrid cooling pump TSB done? Its the Inverter coolant pump. Check for turbulence in the Inverter reservoir when the car is in READY.

    What is the TSB and where is it located and can I do it myself?

    TSB is "Toyota Service Bulletin" which is issued to tell about problems that have been showing up more often than desired.

    There are two independent cooling systems in a Prius. The usual one for the engine ("ICE") which uses a mechanically driven pump and a separate loop for the inverter (power electronics) which is driven by an electric pump. The ICE coolant pump is good for about 150k miles, but is known to leak a bit. The Electric inverter coolant pump is a common source of problems and was the subject of a TSB (actually a recall).

    Replacing the inverter coolant pump is not a hard job, but getting the air bubbles out of the system can take time.

    Got HIV battery changed and put back in. Just went for a test drive and when I turned it on, had to take fob out, the exclamation in triangle wouldn't go away and the charge went from great to 1 bar. Did I miss something?

    Ok, disconnected orange safety and disconnected aux battery. Checked voltage,12.6, then hooked aux back up then put orange safety back in. Started engine, let it sit and think and it ran a little bit, codes self cleared and now all is well! Now I have to reassemble the rest of the car and go and enjoy my weekend. Thanks for all the advice, love his forum!

    Unhooking the 12v and/or high voltage orange safety may make the car temporarily "forget" that it is broken.
    As long as it is an intermittent issue, you might be able to get away with this.

    If it comes back you'll want to get the codes read either with your own code reader, from a local parts store if they do it for free, or a trusted mechanic. The codes will point you in the right direction for a solution.

    Its probably going to come back. Only because you didn't interrogate after install with Techstream or equivalent to check the delta. May have a soft module in that one too.

    Plus the hijack is bad luck.

    Error code P0A80, P3012. Indicated cell problem in block 13 with battery failure imminent. In for hybrid battery replacement at cost of just over $3,000 at dealership. All prior maintenance & TSBs performed except gas pedal revisions which was declined. All I can say is this was just bad luck as failure rate for these batteries is only 3 per 10000 vehicles. It is still a great vehicle.

    Ron,
    Not sure where you are located, but if you are in the Madison,WI area I can install a rebuilt battery with 3 year warranty, unlimited miles for much less than that. Or depending on where you are located, there may be other reputable independents who could do the work for less than the dealer as well.
