    Hello~
    We have a 2016 prius with 100,000 miles on it. We have had no real problems with it except for mice damage (insurance covered repairs) and brake repairs. I’m wondering what preventive maintenance we should consider to have the car for at least another 50,000 miles. We considered buying a 2022 le today (49,000 miles/dealer price $27,000) but someone snapped it up before us. Consequently, we will plan to maintain ours, and hope for the best. Thank you.

    Keep an eye on your engine coolant levels. There's a technical service bulletin for 2016-2019 exhaust gas heat exchangers leaking for those model years.

    Chassis rust may be an issue where you live; but these cars power-train usually will go 150K with just simple oil changes. Your environment is the worse enemy here. If the car is rusting out; I'd do as little as possible.
    On a southern states car I'd recommend all fluids to be replaced, ATF, coolants, brake fluid, spark plugs. Those cars can easily make it to 200K-300K miles, because the bottom isn't going to fall out of them. Sorry...

    FWIW: A new Toyota isn't going to fix your mice issues; it's just going to give them something else to snack on.o_O:(:whistle:

    follow the maintenance schedule that came with the car, or find it online.
    go by miles or time, whichever comes first.
    at 10 years, it's a pretty large maintenance requirement
