    I have a 2013 Prius Plug-In (~150k miles) and I’m looking to sanity-check what a local shop told me about an ongoing brake issue.

    Symptoms I’ve experienced:

    • Intermittent brake lights staying on

    • Corrosion found on the connections on the brake light connected to pedal

    • Multiple brake/ABS warning lights on the dash

    • Stiff or inconsistent brake pedal feel
    The shop believes these symptoms often point to a failing ABS pump / brake actuator assembly on aging Priuses and mentioned this is a fairly common failure. They warned it’s a safety-related repair, requires OEM Toyota parts, and typically runs in the $3k–$4k range. They suggested confirming with a full ABS diagnostic scan.

    Before moving forward, I wanted to ask:

    • Have others experienced similar symptoms that ended up being the ABS pump/actuator?

    • Did your issue start intermittently before fully failing?

    • Were there any alternative causes found (switch, wiring, booster, etc.)?

    • If you replaced the ABS unit, did it fully resolve the issue long-term?
    Appreciate any firsthand experiences or insight. Trying to make an informed decision before authorizing diagnostics or a major repair.

    1) yes, many, but not personally

    2) sometimes

    3) sometimes

    4) yes, almost always

    i haven't had it, but have been reading many experiences here over the last 10 years or so.

    what you want is a qualified toyota shop, not a shop that wants to run 'a full abs diagnostic scan'.
    which sounds a bit dramatic and maybe expensive?

    all you need is a shop with toyota aware code scanner, like tech stream or autel maxi 200.
    once you have the trouble codes, the service manual will guide you through trouble shooting.
    this is a very common issue with gen 3 (2010-2015) and they are correct about the parts and cost unless you diy.
    the problem was so widespread that toyota extended the warranty to 10 years.
    before code reading, it is advisable to get a free 12 volt load test at most auto parts stores and clean up any corrosion found on connectors.

    a trouble code scan by a qualified shoppe is typically $100. - $200.
