What's absolutely required at 100,000 miles?

Follow your owners manual and don't accept the dealer extras.

Unless you really meant what you said, in which case you should just drive it until something breaks, then get it fixed.

 

This is a 2010 forum.

 

Consult the scheduled maintenance guide for 90K and 100K miles (if you don't have the Warranty and Maintenance Guide in your glove box, find the Prius maintenance guide on toyota.com) and do all of those items. In particular, the filter replacements and the engine/inverter coolant replacement. Also note that the iridium spark plug replacement is due at 120K miles.

In addition you should replace the transaxle ATF fluid, the serpentine belt, and the PCV valve. Check your tire tread depth and windshield wiper blades, and then you should be good to go.

 

You probably won't need brake pads yet, mine still had so much left at 100k. Since YMMV, it is better to check it visually.

 

I am curios on how many miles people get out of brakes on a car with regenative braking. What are people getting?

I drive alot of highway miles. On my 2000 Toyota 4Runner I had to put new front brakes on at 170,000 miles and sold the car at 305,000 miles with those same brakes. I never replaced the rear. I would hope the Prius would never need brakes. When stopping I try never to let the guage go past the point the regular brakes start working.

 

The main reason why Prius might need new brakes is due to corrosion of the parts (front rotors for example, due to lack of use, road salt, etc.) - not due to the parts wearing out.

I had recently checked the brakes on my 2004 with 106K miles and the front pads and rear shoes are ~30% worn.

 

I agree. At 60k miles I had to have the front disks resurfaced due to rust and pitting. Bought it @48500, so I know I wasn't the only one to blame. Now I make sure that at least 2-3 times per week (esp. after a rain) I put it in neutral at a few stoplights so the friction brakes clean the rust off the rotors.

 

Yes, it is good practice to shift into N from time to time when at speed, then brake moderately to a stop (assuming no traffic is behind you), so that the friction brakes will operate and dry off wet brake surfaces.
