    I just wanted to remind everyone...tsb for unlimited brake booster milage fix is ending this year then you get 150k coverage...if your brakes have sounded like a goose at moments thats the nitrogen leaking only time will it fail...most brake booster failures happen around 170k to 180k.. I've been following this since the hybrid highlanders from 2008. The biggest problem to get the fix done is the error codes... toyota made sure the error codes had to be so specific and severe...it'll be to late for the warranty and you pay 5k to fix it. .there is a way to force a trouble code. So ypu can get it fixed for free. It is a bit time to get it done but worth it. Let me know if you need the procedure it can possibly save 5k on repairs. That toyota should have fixed.

    I guess I could think of a few ways to do that, but I might save even more money by just telling my life insurance company that I'm actually 20.

    Well to force the error code will only store it in the memory when you put it back it functions normally.. I am just shocked toyota would allow a defective device that can make you lose brakes not be recalled.

    Oh I forgot to mention once you get the new brake booster and actuator you no longer get those constant percolating noises from the brakes priming. This should have been recalled its absurd. If you need help forcing the code please let me know. If you don't get the code you can be out 5k for the fix.

    My 2013 V has had a noisy brake booster ever since I bought it in 2017 with 22K on it. It now has 96K on it. I had assumed all the noises I heard were normal. I don't know if I should be concerned or not. The brakes work fine as far as I can tell.

    There is a strange sound that the booster always makes at about 5 minutes after I turn the car off. Other noises occur randomly, but are more likely during panic stops. I am an Uber driver in Philadelphia, so my dashcam would record any noises. I just need to save some examples.

    That's the self test. What would be weird would be if it didn't happen. I think of it as more like two minutes after power off, but I've never used a stopwatch on it.

    I do hear other noise at other times though. I might start pressing the "event" button on my dashcam when I hear one. I can then post what I just heard (otherwise, it gets overwritten).

    Let me clear some things up... the noises are normal.. however how loud they are seems to get worse over time.. with the replacement I barely notice it.. prior I heard it loudly. And it would always prime and do the noise. If you are competent with tools and have removed the cowel I can tell you how to get the tsb fix.. which I believe should have been done.. because these booster/actuator do go out prematurely i believe they were designed badly.

    And as long as you believe something was designed badly it isn't fraud to fake a dealer out of free ones.

    It's the fact toyota purposely made the warranty last 150k after december.. why? Most go out 170k to 180k... coincidence? If they truly believed there wasn't an issue they would do a 15 year unlimited milage like the ipm. Which they only did because they reworked the software to limit voltage. Toyota is about the bottom line.. and what ever is cheapest

    An open and shut case. Ripping them off is not just ok, it's your duty as an American.

    Good to finally know what they did in the software about the IPM. You can't imagine how frustrating it's been having no access to the source code, and having to guess.

    If you want to act like a ahole you can to someone else.. they provide the overvoltage fix so no source code needed.. the only rip off is trying to pass faulty equipment to consumers.... the fact lawyers have to convince toyota to actually fix problems they know about is whats sick.. you can be a victim all you want but you being a rude person is uncalled for. If I can help save someone 5k for a issue toyota knows about I will. .. up to you if you want to do it or not. You can stick your head in the sand and defend toyota but I will call them out for their BS.

    Yeah, that laziness gets me every time. That article is more or less quoting from the defect information report, which I'm too lazy to find, but the link might work (fortunately I read it a few years ago, before I had become such a slacker).

    You seem to be relying on this part of the report: "if a specific transistor within the IPM fails in a certain way during a high-load driving condition, such as during hard acceleration, there is a possibility for an abnormally high voltage to be generated that could exceed a certain limit in the software and IPM circuit design."

    For clarity, that's describing a certain cause (an IGBT failing, which happens first), and a certain effect (when you open a switch during high current flow in a circuit with inductance, what does the voltage do?) which follows the cause, and that resulting voltage spike is coupled to the MG ECU and triggers a shutdown, when otherwise you should have had limp mode.

    In post #10 you seem to have read that as if their fix was a software change to limit voltage:

    This might be a good opportunity to invite your old electronics prof to lunch and check whether they would read it the same way.

    It might seem strange the two things can be separated, but they can. If I saw somebody else on PriusChat organizing members to rip you off, I would call them on it. You're welcome. That wouldn't necessarily mean I was defending you, or that I wouldn't also call you out for your BS. If they were trying to justify ripping you off by spreading BS about you, I'd call them on that. So it's complicated.

    Ripping them off? So what you are saying is toyota shouldn't fix a defective part that is well known to be defective. Got it and the cases against them to create extended warranties was out of the goodness of their hearts not lawsuits.... the problem here is you think buying a defective part is okay as long as it fails below the 150k.. but mostare known to fail at 170k and 180k ..if you want to spend 5k on the repair up to you. Thats your choice but don't sit here and act like I'm ripping toyota off.. I didn't buy a car knowing about defective parts being passed on year after year. The prius v defect is even covered until the 2017 prius v... again cheaper to push old stock out with the lack of sales than to replace them. Even stevie wonder can see the screw job. But I guess you live a passive lifestyle. I still offer my advice to those who don't want to be a victim.

    My 2010 is already beyond the brake warranty extension, so that's one temptation I no longer face. Ditto for ZF3; if I want a new EGR valve, I'll have to buy it.

    My Gen 1 did legitimately develop the steering jitter within the extended warranty for that, and so I got brand new steering for free in a car that was 7 years and 140,000 miles beyond its original new car steering warranty, and that was pretty cool.

    My clock hasn't run out yet on ZE3, so if I wanted I would certainly know how to trigger the right codes, as you suggest, and jump the line on that, ahead of people with actual failures. Waiting for it to really happen before 2025 could mean I lose out on some free stuff, depending on how the cookies crumble (sorry bisco). Free stuff is worth something, sure.

    Thing is, the guys at my local dealership kind of know me, and they kind of know I don't scam them ... and in life, that's worth something too. Back when it was my Gen 1 steering, it actually saved me some of their normal verification steps, because they knew they needn't bother. That was convenient and saved me at least one return trip.
