    WHY would you want to change the coils, or plugs? Unles the plugs have over
    100,000 miles on them.
    Don't forget about your cabin A/C filter. It's probably nasty if it's never been changed.

    Cleaning the Hybrid Battery fan was the first thing I did after I bought the car. It seemed moderately dirty, but not serious. The filter was moderate as well. I washed it with my garden hose (I let it dry before reinstalling.)

    Engine air filter looks good, I replaced the cabin air filter with a charcoal activated filter. And yeah my car is 141,000 miles. Recently saw a post where somebody was talking about misfires, and showed pictures of extremely filthy ignition coils and spark plugs.

    I don’t know what the previous owner did as far as maintenance, but the Carfax didn’t show any transmission fluid change. I bought the car at 135,000 miles, and I took it to Toyota for a transmission flush first thing.

    I will tell you that my 2015 Prius with 83k miles on it gets 38 in the city and the minute I do 10 miles of highway driving it goes up to 49-50 mpg. I replaced my 12v battery 2 years ago as preventive maintenance. If I just drive stop and go city driving, my MPG sucks. But I got 52 mpg on a long drive to Santa Barbara.

    Also, 2 years ago I had my EGR valve cleaned, new water pump, fuel injectors cleaned, new spark plugs, throttle body cleaned, OCC installed and that other thingy that clogs up replaced that I can't remember the name of.

    If you are doing uber driving, it doesn't get the engine and inverter time to sync together long enough to get you the best mileage. 2016 and on Prius' were changed to get better stop and go mileage.
