    I need your advice. I have a 2012 Prius V 5 with just short of 250k. No rust, and ok cosmetic condition. I replaced the headgasket last year and did a quick and dirty battery rebalance/recondition. I started hearing the ABS pump running too much last November and it finally threw a C1391 recently (OBD report attached).

    Short question: Is it worth $2k to fix?

    Looking at ordering 04006-22212 and 04009-79147 per the CSR, and I have access to Techstream to do the offset and bleed. Pretty confident this job is in my DIY wheelhouse.

    I love the car, but she's getting up there and another 2k seems steep. Do I cut my losses and go buy a Leaf? Gamble on used parts? Tell be your ABS stories and

    Only you can judge your financial position to determine if a repair is worth it. The odds of another hv battery repair is high and a replacement engine could be in that vehicle's future.

    New brake booster assembly parts are recommended since its quite a gamble to use this gen3 used part. A trained Toyota Hybrid tech is given 5 hours for this repair. It would tough to do it twice.

    A used part may not work from a mechanical or electrical standpoint.

    Second a used part can easily be the wrong part as there were at least two different for a 2012 v and 2 others for a 2012 hatchback. Plus the same housing number is used on all four 2012 versions and other years as well.

    The only way to find the right used part requires the donor car's vin which can then be used in Toyota's Electronic Parts Catalog to verify the part number.

    From Toyota's tsb:
    The part number for the remedy part for this campaign should be verified by inputting the vehicle’s VIN into the Electronic Parts Catalog. Use the service part number referenced in the Electronic Parts Catalogue to identify the correct campaign part number to order the required remedy part. DO NOT order the service part number, those part numbers WILL NOT be accepted on a claim made under this campaign.

    Hard to say BUT keep in mind if you do buy the brand new parts those parts will have resale value if/when down the road you decide its time to retire your V.

    Yup.
    Not a doubt about it.
    If the car 'stays fixed' for a year - then your 'car payment' is less than $170 a month.
    You'll have to fix it before you sell it - or take a big hit WHEN you sell it if "change owner" light is on.
    Do you LOVE the car like you say or just 'like it a little' when its running?
    Your call....

    The REAL question is what the heck do you do AFTER it's fixed??

    ...a Leaf??? o_O

    That's in interesting flex because it would seem you're switching from a midsized station wagon sans car payment to a subcompact BEV with a car payment.........in NC.
    Usually it's only 'halfbacks' (*) that do that....
    I once called the 1st gen Leaf a DOT approved golf cart with climate control - and those first gen cars were not really that much better that snarky description.
    HOWEVER!!!!
    (comma)
    The third gen Leaf has a nearly useful range, it only looks as goofy as all the OTHER small import cars and since BEVs are about as polarizing as politics at least half of the nation would rather vote for the other half's political candidates than drive one of the things.
    For a new 'subcompact SUV' (hatchback with normal sized roofline and tires) I'd recommend a '27 Bolt over a '26 Leaf - because of the larger dealership network, greater charging options, and the bow tie on the front of the vehicle - which combines with the lower MSRP to yield a better value.

    If you're going to go with a used BEV - then may GOD have mercy on your soul.

    (*) Half-back.
    People that drive to Florida from the Northeast and only make it halfway back...

    It's worth it even if you have to pay to have it done by a dealer.

    The new cars are less reliable and connected to the manufacturer and the dealers through the telmatics.

    Given to the the high price of both good used and new vehicles and the lockout of non dealer tethered repair with complicated electronics, $2,000 is chump change.

    Halfback, I like that. We have a truck, minivan, and motorcycle so the Prius has been relegated to the around town grocery getter beater. I like the description of the 1st gen leaf as a golf cart since that's almost what we need. Surface street capable with like 20mi range for the weekly shop. I've actually been wanting to drop a Gen 2/3 Leaf drivetrain into a "vintage" roller car to make an around town go-kart/mini off grid solar storage, but that's a project for another day. And don't worry, I won't be getting a car payment. I'm allergic to buying anything over 10k, which is how I landed here.

    Ok folks, you've convinced me. I just needed another couple voices to push me where I wanted to go. Parts are on the way and I'm $1800 lighter. I'll be back when it runs or I give up.

    Ok, we're about 2 weeks out from completing the repair, and so far so good. I bought the parts from Olathe Toyota, since they were WAY cheaper than my local dealer. The grand total was just over $1900.

    The repair itself took about 7 hours from starting to get tools out to being totally cleaned up. If I were to do it again I think it would take half that or less. By far the hardest part was the Pump/Accumulator (The thing that looks like two big cylinders). Getting it out and then getting the nuts to catch on the new one was really fiddly. Doing the brake bleed was just a pain laying on the ground, but not technically hard (You should go find the 8mm line wrench now, because chances are you don't have one).

    I used a Gearwrench GWSMARTBT OBD tool that I bought on Marketplace for $40. The brake bleed option asked if I replaced components and when I said yes it tacked a linear valve offset to the end of the bleed.

    WARNING: I heeded the advice I read here and put a charger on my battery before and during the procedure and it STILL wasn't enough. The offset process kept making the car reboot over and over. I ended up needing to use the charger on 30A which let it run fine, but it seems like it pulls a lot of power.

    Overall, the process was really straightforward and if you're mechanically inclined and patient I say go for it.
