    I have about 100000km on my 2017 Prius
    Not sure if it’s because I live in Canada Ontario and the salt destroys the brakes.

    i replaced the front pads and rotors at 70000km and rears at around 100k
    Both times down to metal.
    I did regular brake service and the brakes wore fairly even within 5% comparing from passenger vs front driver and same for rear.

    I replaced the front with Toyota OEM dealer parts and rear with aftermarket Napa premium parts. I used to be the biggest fan on how Toyota brakes last and wear on my previous Tacoma, the Prius being a vehicle that conserves braking with pads is subpar what I expected. They do great during summer but get destroyed in the winter. The Napa rears seem to be overall treated better you are way less rust blooming and flaking.
    Not thrilled with Prius OEM dealer brakes

    there have been odd reports of all generations with brake problems due to salt. maybe it is strictly personal use conditions, or some are just defective.
    on the whole, most have no issue

    I feel it’s the area salt, and how the metal reacts. High humidity with weather -30 to +30
    Parked outside, I’m ok with changing the brakes out after 70k km, but hoped for more.

    I have replaced the rotors on four of our vehicles so far with zinc plated ones ( PowerStop brand ).

    They have been holding up far better than the OEM rotors did...and we are in a high road salt area. Full disclosure that I did this as an 'experiment' on the first vehicle ( 2012 Prius v wagon ). I liked the result so much that I have been swapping the rotors out on the other vehicles when the time comes. For me it's a 'why not' type of thing at this point since I'm in there doing a brake job anyway.

    I've got around 93K kms, and when putting the snows on I see the front pads are around 6mm still. Maybe punishing amounts of road salt in your area are corroding the rotors, accelerating wear?

    Rear pads I had to replace early, and they're currently maybe 8mm. I messed up rear caliper piston orientation first time round.

    Rotors all fine.

    My brakes are still fine at 140K on my 2017. I guestimate my miles are about 60-70% highway. There is a saying that salt is harsh on everything but saltwater and saltwater fish.

    My parents have a 2014 with at least 80k miles at last check in Chicago, which should have fairly similar road surface salinity to where OP is, and I am fairly certain it's still on the factory brakes. I haven't exactly taken the wheels off and looked at them in person, so not sure what state they are in, other than being functional and the mechanic not telling my dad it's time for new brakes yet.

    Although, I'm also not surprised that Toyota maybe used inferior brake components on the Prius as a cost cutting measure. It's not a performance car by any means so quick stops aren't super important (except you know - for safety). Also because in most normal conditions MG2 is doing a good deal of the work, from a durability perspective, even crappier pads and rotors will still (typically) outlive nicer ones on a conventional vehicle.

    Yep, salt is our Kryptonite! I hate it! I'm originally from Maine and "rust bucket" is what a car becomes in too short a time period!
    Do you have any car washes that run in the winter? We have one that has the under-carriage spray and I'll run my cars through it during the winter (when it warms up over freezing) after we've had snowstorms and that seems to help keep the rust down. (They do use salt in Colorado but also add corrosion inhibitors so I don't think we get rust as bad as Maine used to....not sure if Maine is better now or not.)
    Anyway, I do all my families brakes and have favorites....Bosch rotors and Import Direct pads (ceramic for cars, semi-metallic for vans and trucks) IMHO I don't think they are much different than the OEMs Toyota uses.
