    I would find another dealer Toyota or Lexus. Its hard to imagine why a full brake job was needed at 30k other than some normal noises like slight corrosion build up overnight that squeaks for a minute in reverse. $100 oil changes are ridiculous as well. The dealers around here charge $59 for full synthetic and often you can get a two for deal. Plus they do their multipoint inspection including measuring the brake pads. Remember rotors can warp under normal use if they are overheated by long downhills and then quickly cooled. But that is rare as well.

    unfortunately, a small percentage of cars are defective, even toyotas

    I am 1 day away from my appointment. My Prediction... I get another 'brake job', likely front & back. My next prediction... My wife gets her Rogue instead of the Rav hybrid I was trying to convince to get. Fingers crossed I am wrong and it turns out to be something short of brake replacement. I am now convinced from discussions here and other reviews I have read the brakes SHOULD be lasting longer.

    Just a wild extra input for consideration. The car has a noise maker speaker up front near the drivers side bumper that is intended to warn pedestrians that you are there moving slowly in EV mode. Seriously. It only comes on at low ev speeds and goes off with a full stop.

    There are two variables here:

    1. Is the problem something with a simpler fix than brake replacement?
    2. Will the outfit you get your service from do the simpler fix, or just throw brake replacement at it?

    Take the car to the wrong outfit, and your worst-case prophecy comes true, you get brake replacement, needed or not.

    Lest you think me excessively cynical, here's an example from the PriusChat archives where a customer trusted her dealer three times in a row, asking about (most likely) brake noise from flash rust (which all of us on PriusChat know how to erase in a few seconds by braking in neutral, right?), and instead of explaining that to her, the dealer sold her $1400 "brake jobs"—every chance they got.

    she should get the rogue if she wants it, regardless of you brake outcome.

    my son has a rav4h, and his wife has a murano. they like both cars.

    Dropped off at dealer.... Got the usual 'here in the northeast corrosion is the problem not wear". As soon as I hear it I knew I had heard it before... "Flash Rust" "Breaking in Neutral" ??? New to me. I did the panic stops but think regen worked rather than pads so doubt it helped at all. What was the 'flash rust' fix ???

    Flash rust means minor corrosion on the rotors from sitting when wet. It goes away quickly under normal use but can cause some squeaking in the morning especially the first use in reverse. If they tell you its ok I would go with it. Braking in neutral? I don’t have to do that to get rid of the minor rotor corrosion. Just drive it.

    When my brakes get flash rusted, generally from being parked outside over a soggy night or weekend, what I notice in the morning is not usually "some squeaking" but more like the sound and feel of dragging a large sled of rocks (but one that magically disappears whenever the brakes aren't applied). The combination of the sound and the extra grabbiness, to someone who hasn't read about it on PriusChat in advance, can legitimately seem as if the whole brake system is on its last legs.

    I have known it to clear up in normal driving without the brake-in-neutral technique, I'm just not that patient. It'll be back to fully quiet and smooth again by maybe my third commute to and from work.

    If I just shift unobtrusively into neutral ahead of each of the three stop signs on the way out of my neighborhood, it's all better by that point, and I don't have to grit my teeth for two or three more days waiting for normal driving to do it.

    That was the technique recommended on PriusChat when I first read about it 11 years ago, and it never really goes stale.

    Drum roll... the results are in. I won and I lost!
    I won.... front left rust ridge removed... $54
    I lost.... "Rear Brakes are worn almost to metal"
    Replace rear pads and discs. Clean Calipers.
    Pad kit $67
    Anti Shim Kit $39
    Disc x2 ($80x2) $160
    Total damages with tax less $30 loyalty coupon $480

    Not the best experience. I went to service desk they said car is done. See cashier.
    Gone are the old days of explanations and bedside manners.
    BUT the car no longer makes thumping noise and braking does seem more solid ?
    ....
    Thank you for your tips, suggestions, and general sympathy...:)
    Now I can stress over something new....

    Strange about those rear brakes. My guess is they did not do them the first time. No way they wear out before the front even if you treat them like an eighteen year old teenager.

    The trick to 220k miles and counting on my original factory brakes is to anticipate stops whenever possible so that hard braking is not needed very often. The regen will then do 95% of the deceleration leaving the friction brakes for the last few mph. It also helps your miles per gallon.

    That dealership must be located near the Cape Cod Tunnel...

    Did they give you the option of keeping or examining the old parts?

    I believe that's still a thing you're allowed to ask.

    All in all I guess I am satisfied. I agree backs likely were not done when they claimed they were at 30k. At least the front were accurately diagnosed. Remembering I paid nothing for the 1st brake job at 30k makes the cost somewhat reasonable. I still am a bit annoyed with the "See Cashier" response when picking up the car.
    Re: Cape Cod Tunnel comment. We will be using "it" on Thursday when we head to Cape for 4th of July. "Tunnel' sure beats the bridges as long as we keep it a local secret. The 300 mile trip each way from Saratoga region of NYS was part of the reason I decided to get a diagnosis from the dealer. Did not want to start having grinding noises when I vacation.
    BTW My V loves the Cape. I get 47mpg on way there then 50+ coasting around Cape.

    She should go for the Rav4 hybrid. See this new video comparing them.

    What the hell kind of oil were they putting into your car for $100? Oil made from Unicorn tears?

    If you'll forgive a bit of snarkiness:

    My prediction: the CVT on that Rogue will crap itself (replace crap with the more appropriate but less polite word) in short order, but not before everyone sees you as someone who can't get a better car because of your assumed-to-be-terrible credit (I keep hearing jokes about Nissan's willingness to finance household pets, e.g. a well-trained Golden Retriever).

    (to be clear, this is a joke and I am laughing with you, not at you)

    Might want to call around your area to get ballpark quotes from other dealers for the same job for future reference. I've noticed quite a bit of variation in dealer pricing for service in our area (don't know about Cape Cod). For example, those rotors (part #42431-47050) go for $55+shipping each online.

    Also, look at this TSB, quite a bit of overlap on the parts that got replaced (maybe you can appeal some of the cost if the fix hadn't been applied?): https://www.procutusa.com/pdf/oem/Toyota_Prius_TSB.pdf
