    As we were driving, the ABS, Brake and traction lights all came on and I notice it's harder to brake. I can still stop but I have to put more weight down. Had my 2015 for a month and no issues clean Carfax. 112k miles, what could be going on?

    Basically when you get the code read it's going to be a bunch of c codes to do with brake pressure accumulator pressure and so on when you post those codes up then all the people will chime in with your problem that's how this works over here generally If you can't get those codes then you'll get a bunch of post about code readers you should buy so that you can get those codes if you have no interest in that take your car somewhere that will be able to get the codes and get a printout and then come back here and post up the printout pretty much that's the long and the short of it The real short of it is is more than likely your brake parts on the firewall of your generation 3 or failing they're about 12 to $1,400 for the two pieces If you're smart you buy them online have them sent to a store and pick them up and have them privately installed or you don't care about any of this and you just write a check and send it to the Toyota dealer.

    You need a new brake pump.
    DIY around a thousand, dealer around $3-5,000.

    that part's correct: when those lights come on, means it's time to read the trouble codes

    that part's getting ahead of the game: once you have the codes, they can be "to do with brake pressure accumulator pressure and so on" or to do with something else. There are about two hundred trouble codes defined for the brake system.

    That's why reading the codes comes first, and deciding what the problem might be comes later.

    Yep you're absolutely right Just getting everybody prepared for the expensive repair that's about to come really with these cars you've got to be careful in making the choice to take the plunge a few extra miles per gallon is very expensive in some of these vehicles

    I am new to this and the Prius world. I wanted to start a new thread but could find no way to do it. It seems wrong to "reply".
    So, I just bought a 2010 Prius IV with the understanding that the 200 volt battery and 12 volt battery need replacing. The previous owner was driving 2 years ago when the engine suddenly quit. It has been sitting for 2 years. I just heard a noise coming from the brake pump every 3 seconds. The dealer wants $4000 to fix the brakes. I cannot do that. Does a company make replacement master cylinders (booster) and booster pumps? If I drive with bad brakes, will it cause the engine to suddenly quit? What are the questions do I ask an ebay vendor to know if his parts are the redesigned brake parts or if the parts were removed from a car that was junked due to bad brakes? A man on youtube installed ebay parts that were bad and replaced them a 2nd time with bad ebay parts. The new parts from Toyota are $1143 plus $1115= $2258 After I install parts myself, must I have Toyota dealer adjust "offset" and other adjustments? Do many mechanics have the proper tools?
    I am trying to love Toyota, but this makes it hard.

    You're jumping in on the car that would make it impossible for you to love Toyota if you didn't know Toyota before You're jumping in when planned obsolescence has been completely updated and placed very carefully in the system so you'll never know the Toyota I knew but that's okay now you're starting to deal with some of this problem because of well probably not understanding or doing the due diligence before you bought the car these cars are made in this way that's why you see them all on the marketplace for seemingly ridiculous prices for a car that might get 50 mi to the gallon if everything were right in the solar system in your world. So there are tricky things like that at play here The parts you speak of the two brake parts there are updated parts for the two pieces somebody will come along here in a minute and try to give you the numbers they're on silver and black or white and black stickers on the individual parts If you look at your car you might see the stickers on one or two of the brake parts those numbers got updated with the newer parts but they don't necessarily make the older parts bad there is a changeover to something in mid model change of the generation 3 I don't know when it took place I don't really care people will be along that keep this information and use it all the time I do not there are no rebuilt parts that I know of for these two pieces as far as I know there's no in-house rebuilding company that's doing that A1 cardone or anybody they do for other makes and models but not for these so there must not be a good market so on and so forth something because A1 cardone would be on it if they could be reasonably they do everything else. Your choice is now or to buy junkyard parts and pray for the best go through the job possibly too maybe three times or by the Toyota new parts at the new prices and now you'll have I don't know what in this car 6 $7,000 by the time you get done The Toyota dealer does not need to bleed the brakes but given how we're discussing things here it might be a good idea capable expensive scanners can do the Brake bleed procedure like Autel series 6 and up I believe But they are reasonably costly tools to purchase and just have sitting at home to bleed brakes and do higher and things on your Prius once or twice in your life but if you're going to own a Prius and moving forward cars similar to it might be a good thing to have some people can justify it some cannot there are ways to get Toyota's tech software. But it's either costly or you're doing some hack to get it to work and then does it work right. This is why you have to be careful moving forward with electric hybrid and those kinds of vehicles because regular people don't really understand them very well yet so it's real easy to get bilked into buying something that you really wouldn't have any part of until you heard 50 mi to the gallon It cost money to get high gas mileage even more money to get rid of gas in itself as you see with people falling into the electric category calling tow trucks to be towed and can't find chargers and this and that breaking battery's going bad because this is all kind of new to everybody and those people are picking up the bill they are the guinea pigs. But basically with the generation 3 if you're on any kind of budget you're kind of already up that creek without a paddle even though these cars are fairly well known by now as you see parts are expensive everybody thinks they have something and so on everybody wants 50 mi to the gallon but not a lot of people get it You're going to get about 46 really 47 maybe something along those lines The people that are getting 50 plus miles to the gallon or not the kind of people you're happy being behind ever when you're driving. Really reading reviews reading discussions on other groups even here You can clearly see that the generation 3 is not where you'd want to be unfortunately for you if you looked at 06 to '09 you probably wouldn't be here you'd be driving the car that's kind of the reality of the situation unfortunately. There are a lot of generation 3 sitting they look good sitting in the yard they're great yard ornaments and when you stop and talk to the people or anybody about what's happened they all need $4,000 in parts 6500 in total to make the car move or whatever quite quite the thing and then the interior is very plastic and very non-durable armrest cave in they're just all kinds of little things but make the car not.

    This maybe wasn't the best thread to jump in on, because it's a recent active one about an issue Gordon773 is having, and we still need Gordon773 to come back and report what the trouble codes are for that issue.

    Speaking of which, @Gordon773: did you have anything plugged into the obd port, when you got the warning lights and odd brakes?

    I had your symptoms, several times, with increasing frequency, and it was likely due to ScanGuage II, constantly plugged into OBD port. Perhaps due to always weighing on the the port. Dealership mechanic noted that his techstream cable connection was spotty. Anyway, I discontinued using the SG, problem never reoccured.

    I have had 10 Toyotas, starting with 1970 Corona and 4 Celicas. I love them so much that I was blind to the obvious problems and not asking many questions. 229,000 miles on 2010 model IV. I thought all of the fault lights were due to a dead high voltage battery.
    The 200 volt battery was dead for nearly 2 years. I assume that it is totally ruined?
    BRAKES
    When I buy the brake parts from a junk yard, I will look for a redesigned booster pump with the label placed long ways on the pump. And I will look for the redesigned master cylinder with part number 47050-47140 and not 47050-47060. And I need to be sure that the 2 pieces came from the same car? This is no guarentee because I just read about Gordan773's brakes failing on a 2015 with 112,000 miles.
    I might postpone the serious repair. Almost all of my driving is highway, so the rarely used brake regeneration will not help my gas mileage. (As long as I can stop safely) (Will it pass Virginia inspection?) My dealer wants $3993 plus tax to fix my brakes. Parts are $2258 plus tax.
