    Hi everyone. I bought my 2006 prius in october of 2020 with 63k miles. It now has 81k miles and in the past year I have done the following:

    -changed transmission fluid
    -changed engine coolant
    -changed inverter coolant
    -cleaned HV battery cooling fan
    -cleaned throttle body
    -replaced pcv valve
    -installed cat security shield
    -replaced pads and rotors
    -replaced spark plugs
    -changed the cabin air filter
    -changed the engine air filter
    -and of course oil changes every 5k

    I want my prius to last 300k+ miles and am wondering what preventative maintenance to do next. I may be caught up for awhile, because I have been searching through the forums and cannot find anything else but would appreciate any leads.

    Thanks!

    Well the HV battery, brake actuator, combination meter will all eventually fail. So save up some money to repair those items when they fail. New parts will run you into the thousands (except combination meter)

    Sounds good ill keep that in mind! i monitor the voltage differences in my modules and the max and min almost never strays from .2 and from what i’ve seen on google searches that’s a good thing. have no idea abt the health of my brake actuator or if you can even monitor that

    Those items don't really need to be monitored. When they fail, you just replace with new. Don't waste your energy on stuff like that, it's not really in your control

    Change the brake fluid.

    Replace wiper blade inserts, if needed.

    Check the pressure on the spare. Clean up while you’re in there.

    Check the 12 volt battery with an electronic load tester, see where it’s at.

    Raise the car (safely), say one end at a time, clean up suspension rust and apply rust proofing. Remove plastic panels for better access. Back out any small bolts/screws, oil soak them and reinstall.

    Lube all door hinges, ditto for good and hatch, license plate bolts.

    all great things that i never thought about, thanks! there isn’t any suspension rust but now that it’s not garage kept and driven in the winter I would love to apply rust proofing to prevent it! which product would you recommend?

    Fluid Film is highly regarded. Haven’t used it myself though.

    I used boiled linseed oil (readily available in hardware stores and paint places) by the quart, applied with foam brush. It’s worked out well; even over existing rust, seals and stops it, quite durable. It was recommended by @tvpierce IIRC. :)

    For small bolts, any thin oil Is good, say something like three-in-one.
