Regarding maintenance

How many extra bucks?

 

I don't want to influence you with my take on what I read in your OP, but if you have the $ and you want the service, well.
Or you could get a second opinion from another shop, either toyota or independent.
What are your thoughts on #8 on the list?

 

Yep. it sounds very muich to me like what a service writer at the dealership would try to sell.

 

I think 7 should be done at every sevice call. I think 8 is a complete no no - oil additives change the viscosity of the 0 20 oil and not in a good way.
And how often someone gets specfic services always depends on the way the car is driven and it's conditon at time of service. Everyone has there own personal preferences to service intervals, including the dealers service writers.

 

Sorry, I don't know what to tell you about specific services. There may be good reason to flush and bleed the brakes on your car. Have you looked in the brake fluid resevre? Does it look low of dirty? Do you think the brake service is a wise preventive service? If, yes than have it done.

 

If I were you, I would not do anything beyond what the regular maintenance Toyota calls for at that interval, unless you have a problem. That means do 1-4 and call it done. That being said, 7 should be done free of charge for a multipoint check for topping off the fluid. And 9 is something Toyota forgot to write down on the manual, but maybe should be done every 3 years or so, or at the least check the brake fluid. 5 can be checked visually and if not dirty, don't need it. If they are dirty either clean or replace yourself. I am surprised that they did not list the air filter and cabin filter change in the list. 6,8,10,11 are not needed, IMHO.

BTW, is your car Prius Prime or 2017 Prius Two? Either way, the needed service should be very similar.

 

I don't have much experience with Gen4, but from what I have read, 45mpg is on the low end of the spectrum. If your drive is mainly very short stop-and-go city drive, then it may be a reasonable number. If not, usual suspects are tires (either very new or very old or low pressure) and bad 12v battery.

 

I have never done brake fluid DIY. For Prius, there are two ways of doing it with TechStream or without. I am sure others will chime in on this, but any shops should be able to do it. You can ask how much for the full brake inspection and fluid replacement, but it should not cost much more than $100. Again, if the fluid is checked and no degradation (moisture in the fluid), it may not need to be replaced, but if you have never done thorough brake checks and cleaning in 3yrs 55kmils, it may be a good idea to get the brake serviced now.

 

I know people get nervous about brakes but the fluid doesn't need to be changed unless moisture gets into it. You can buy a brake fluid moisture tester from Amazon for less than $10. My Prius is 11 years old and has never had the brake fluid changed. My tester shows no moisture.

For a counterpoint: Toyota Canada recommends to change brake fluid every 3 years or 48k km (30k miles).
