    Keep the receipt for the tow. Toyota should cover it because of the warranty.

    Lucky I have AAA, with the fancy version that gives me 100 miles of towing. I can have the car towed to the dealer.

    So I think I've got my questions answered. The diagnosis is possibly off, but it sure sounds right to me.

    Many many thanks to all of you. This is new territory for me and the guidance has been good.

    God Bless Us All.

    You've got the car giving limpy acceleration consistent with impaired flow of electric power in the transmission, giving you a full set of trouble codes pointing to the power inverter components, and qualifying you for free replacement under the known history of failure of power inverter components.

    I've seen other diagnoses more likely to be possibly off.

    Good. I will be glad if it's right.

    BTW, is that a regular descriptor -- limpy acceleration?

    It's a technical term. Once you've completed University of Toyota training, you're allowed to use it.

    Well, it's a really good term, clear in its meaning.

    And I take it you completed U of T training since you used it.

    And thanks again, you've been a big help in this.

    So where did you get all of what you've got?. Wiki University? The School of Greasy Hands and Busted Knuckles?

    And a further input that makes it sound like inverter not battery.

    I mentioned in my first post that his mom is the owner of record just now, and he is buying it from her on monthly installments. She told me last night that she bought it used, and before buying she had some kind of test done of the battery condition. She said the test indicated 70%, though I can't remember now 70% of what -- 70% of the original power? 70% of its original lifespan remaining? In any case it gave her confidence in buying it.

    So I'm hoping it means the battery was not at death's door. But things die for reasons other than scheduled failure.

    I'm aware of some apps, like Dr. Prius maybe?, that do purport to give you a % of how far the battery is from joining the choir invisible.

    I don't really know by what incantations they come up with that number, or how realistic it turns out to be in practice.

    From observing PriusChat over many years, I have a sense that many people worry a lot about the battery, it being sort of the one thing that everyone who has heard of a Prius has heard of worrying about, while really the batteries do last a pretty long time, the cars have plenty of other things to wear out, and on whatever day you decide you're done with the car, you may be making that decision for any number of other reasons.

    I also sorta wondered how she tested it and how reliable the test might be.

    But let me back up and ask again - how did you get to know all you know, if not by way of Toyota U? I'm interested because

    <you can skip the rest if you want>

    everything I know about ICE's I learned by doing (and I learned "limpy acceleration" and "ICE" here). I graduated from an elite college without knowing anything about cars. Then my first car of my own was a VW bug, and that was was at the height of my hippie days. I was getting interested in all those New Age ideas, like back to the land, grow your own food, learn to fix things yourself, all of that. And I learned to do my own simple maintenance - change my own oil, check my own timing, adjust my own valves. That was all so much fun. And then my bug started leaking oil. I hunted for that leak for so long, while topping it up every day. Finally I found the leak (in a place I hadn't learned about yet) and fixed it myself, and I was so proud. But I quit checking the oil every day. Turns out I had TWO leaks, and soon I burned up the engine. And THEN I decided to rebuild it myself, bought all the parts, borrowed someone's garage, borrowed cars here and there as needed (I was working at home, doing stained glass). When it as all done, I turned the key and it started right up! And ran for many thousands of miles after.

    So that's where my question was coming from. At some point my life took a different direction and I began to let my mechanic fix my cars. If you're still here, thanks for your interest. And if you care to respond, "25 words or less" will do. :)

    I might be a tad younger; those hippie fix-things-yourself notions were things I absorbed as a child rather than first living as a young adult. My first car was a heap sold to me for $1 when I was 15 to see if I could make a driveable car out of it, and it was my daily driver until a couple of years after college. (I had to leave for college while its engine was still in a lot of labeled zip-loc baggies, and I finished the rebuild while home on winter break, which tested how well I had labeled them.)

    My time in college was probably helped by my having enough practical interests and questions already when I entered that I could clearly see how concepts in class applied to them, and never made the mistake of thinking "book learning" was some unrelated other thing, the way so many people seem to. Good profs don't hurt, either.

    Later on, there isn't the advantage of people who are paid to be there and make sure you learn stuff, but you can keep doing it using the habits they helped you form.

    "ICE" bugs me, doubly so when you hear "ICE engine", which basically means "Internal Combustion Engine...Engine". But yeah, pretentious acronym, do we seriously need to stipulate that our engines are of the Internal combustion ilk...

    Then some don't see the need to capitalize, start talking about the "ice water pump".

    Ah, where would we be without our PriusChat shibboleths? Would we let Joe Blow just come in from anywhere and talk about his car having an engine?

    As for the ICE engine, well, it's controlled by the ECM module, which is powered by DC current. If you have to stop fast, the ABS system might help. With luck, that won't happen on your short trip to use the ATM machine.

    That all makes me think human brains just want to have the main noun out in the open in the sentence. People who think up acronyms always want to roll the noun in as the last letter of the acronym, which might just be fighting human nature and people will keep prying the noun back out when they talk. If acronym-maker-uppers just learned to roll with that, we might have IC engines, EC modules, AT machines.

    In some engineering papers about engines, I have seen "IC engine" used.

    So there's more than one?

    I've long thought that we are an interesting species.

    I did make that mistake. It was long after graduation that I began to see value in a lot of the courses that I took just because I had to take them to satisfy some requirement.

    And the ICE thing. You will note that I didn't stumbled with the redundancy issue. That one is new to me, and I can see how it's convenient in a lengthy post in a forum, but yes, I am well familiar with that kind of oddity. And I've spent 10 minutes or so trying to think up this one particular familiar instance of it, one which is utterly common, but at my age now, another utterly common thing is to go blank trying to recall something that's as common as water but I've lost the handle for it. That's the one thing (so far) that really bothers me about this aging thing. And when it does pop through the brain fog, it's just so curious - how could I have not been able to find it?

    Anyway, thanks all of you, for the good advice and the patience of helping me out with it. And I've run on and on today -- my wife is away for a long visit to the grandkids and I have no one to talk to for a while.

    All right, enough. (y)

    That was the accepted phrase when I was in school. I took an IC engines course, which, by definition, didn't cover external-combustion engines. It hypothetically could've covered gas turbines, but didn't.

    Writing about an "ICE" in a context where it's obvious the automotive engine under discussion is of the internal combustion sort seems inane to me---as well as pretentious, as Mendel says. Not many of us drive Stanley Steamers any more.

    Just for fun, what other shibboleths are there?

    Unless they are not fun to mention . . . .

    I can be curious about lots and lots of things, not just how some gizmo works.

    Hmm, I'm trying to think of more, and maybe we don't have so many really.

    ICE makes a pretty classic shibboleth, because if you showed up unawares there's no reason you wouldn't just say engine, and then we can point and laugh and exclude you from the feast.

    I've seen "HVB" used now and then in posts, which might be sort of an anti-shibboleth, something newcomers will show up thinking they ought to say to sound hip, only then to catch on that we mostly just say traction battery or HV battery or just battery when it's clear which one we mean.

    Terms like PSD (the power-split device in the transmission) and MG1 and MG2 (the two motor-generators in there) are ones you might as well know if you're hanging out here, but maybe they're not so shibbolethy really because they don't substitute for something else you might say instead; if you've heard of those things at all, it was probably already by those names.

    shibbolethy? Did you mean shibbolethistic?

    And I probably won't be around here after this adventure, although with a 12 year old car, I might need help on the grandson's behalf another time. He's super smart, but it's in software and design areas, not clanking mechanical stuff.

    And my own interest is over at Tacoma World, where they are also really knowledgeable and helpful. I've had nothing but Tacomas (Tacomae?) for 35 years now. And when I lost my beloved 2002 early in the year, I went right out and bought a new one. But it was sad. I had 270,000 miles on it, and it still ran smoothly, but the state of NH said I couldn't drive it on public roads any more. The inspecting mechanic said he could have put his fist through the frame. Rust and tooth decay can be delayed but hard to delay forever. I have a lot of crowns.

    I like the new one well enough, but I wish they still had a stick shift option, outside of the models in the upper versions, the sport packages and all that. I just didn't want to spend that high.
