    Since my previous post I’ve been able to diagnose that the whirring sound I’ve been having is the brake actuator. It makes the sound about every 30 seconds.

    I’ve seen the entire installation from start to finish and can’t understand why the labor is so damn expensive for this job. It really isn’t complicated. I don’t like doing mechanical jobs myself but the labor is way overpriced. The part is also ridiculously priced. Millions of Prius on the road and they want $500+ for a used part. I’ve been leaning towards making an offer on EBay on the part out of a totaled Prius.
    Does anybody do the entire job for a reasonable price? What did you pay when yours failed? Any suggestions to make this the far cheaper repair that it should be? Thanks!

    There's two pieces in there I'm going to want to replace them both. That's how Toyota does a job and they won't usually do it any other way because they replace one part and then the other ones fails directly now you have to pay the same labor almost twice so go at it like that yeah sure and your driveway you might get lucky and replace them part with the pump and accumulator and get away with that until you get out of the car maybe and if not then you're doing the labor over again so there's always that. Each part is around 700 bucks You might get a discount ordering online and haven't sent to the local Toyota dealer and picking it up that way maybe. You may be able to get it out of the EU or places like Pakistan with the shipping will put you equal or a little above buying it here so that's problematic but this is just part of owning this model

    When you do the job you'll understand why it cost so much when you have to do these things to make a living at it not just once every so often on a weekend quite a bit different You seen the job start to finish on a YouTube video sped up. Make sure everything else is good with your car because these cars are known for engine problems and all kinds of funding nonsense You think you're having a problem now.

    The video took 3:54. Sped up or not that is not a difficult job worth $700+ worth of labor. I’m not really worried about the problems with the Gen 3. Ok so the head gasket can/will fail? Engine swap. Already been quoted on that and it’s not even that expensive. Same thing with the hybrid battery.

    I rather just buy both parts out of a wrecked Prius. Which part is more prone to failure and actually causes the sound?

    That's the trick . But usually the piece with the majority of the electronics.

    That's two questions. One is easy. The sound comes from the bottom one, where the pump is.

    [​IMG]

    The other question, which one has failed and is making the pump run so often, is harder. It can be either. If you're going to gamble, the odds favor the top one because more valves are in it, but that's just a gamble.

    Are you saying the video was three hours fifty-four minutes, or three minutes fifty-four seconds?

    If you think you might replace the bottom part, it could be good preparation to review this PDF. It outlines a faster way to do the replacement that doesn't require the front suspension crossmember out.

    Well we’re dealing in a lot of things that can happen not have happened. Currently my hybrid battery is fine, engine is also fine and actuator although starting to indicate signs of failure is causing zero issues with drive ability.
    Now based on the impressive gas mileage of a Prius, low purchase cost, and overall reliability in general tell me the vehicle I should buy instead. From what I understand all
    Prius have various failures that can happen.

    Thanks for that explanation it’s actually helpful. I was trying to understand which parts are which and what needed to be replaced. I’ll probably get both parts out of a used Prius. Considering my Prius has 182k and is just now starting to fail I like my odds on a used one.
    The video was 3 minutes and 54 seconds.

    Just to clarify these are both parts needed in the picture correct?

    Well, I've already put more cash into both my Gen 2 and Gen 3 Prius in repairs than my 2007 Ford Focus with far fewer miles on them. That Ford was reliable as hell until it got totaled by a drunk driver hitting me. My 2003 Ford Focus was also super reliable and awesome until I crashed it. On the other hand, stay far away from post 2012 Ford Focus. Transmission issues and electrical issues galore.

    Neither my Gen 2 or Gen 3 has yet reached 300,000 miles. My 2007 Ford Focus reached 299,500 miles and the secondary air intake and the motor mounts were like the only parts I had to replace other than batteries, tires, and brakes.

    The Prius is awesome with the MPG, but overall I'm not sure I'm saving money versus my Fords because these Prius are perpetual money pits with constant failures of ICE/Inverter water pumps, coolant control valves, etc. (Gen 2), Combo Meter (Gen 2), Brake Actuator/Pump (Gen 3), EGR Valve (Gen 3), etc.

    That dreaded check engine light, triangle of death, etc., is all too common and haunting.

    Don't get me wrong, I love the Prius in general, and I hope in the long run the mpg saves me money over my Fords and parts will stop failing after I replace almost everything that was left for me to fail by the previous owners, but mine were both new to me with around 200,000 miles on the clock and both required me to put a lot of elbow grease and new parts into keeping them running.

    And then lending my Gen 2 to a friend I've had the fun of replacing more parts due to crashing into boulders and mailboxes and stuff. I'm getting very familiar with wrenching on these cars.

    I'm super invested into Toyota these days since I have a Tacoma and probably will get a Sienna Hybrid one of these days. Solid cars for sure. But the 2003-2010 Focus was a very reliable car.

    I'm here on THIS thread because my lights on my dash on the Gen3 just lit up and my code tells me I'm suffering the same problem as you right now, or a similar one.

    Those look like the parts to me, but my experience so far is literally just watching a few videos and scouring some old threads here.

    Yeah this is really common you'll be doing basically the same thing and that's that It happens in the generation too also there's just only one part here they split the stuff up I figured you'd have more money because you bought the car so I guess that's how they work this stuff out in their mind I remember when ABS units were $5,000 in the late '80s for the BMWs and whatnot so $1,400 doesn't seem like anything really too serious what I'm really wowed about is no rebuilder coverage that's almost a joke

    I don’t trust Ford cars at all. Even their trucks are inconsistent. I guess I’ve been lucky. My Gen 2 which I sold to a friend that needed a car has needed zero repairs (way over 210k miles now). My Gen 3 rides perfect but I know with enough time this brake problem is going to fail. All in all the engineering of Toyota and the superb gas mileage will make me deal with the all the issues with this model. I’m just looking for cheaper ways to do things and I know I’ll find them with patience. I’ve already found batteries with 3 year warranties for under $1k. That used to be way more.

    Yes all that stuff comes down over time when the Prius first started out 20 years ago you know a battery was four grand or $5,000 and all this and that and only the Toyota dealer had it could do it and so on just like lots of that stuff when ABS first came out so me all day or may not remember all those fiasco's but it all comes out somewhat in the wash.
