2001 Prius received 8/01, 78k miles to date. It has had the SSG 40C (HV battery resealing), TSB EG 011-03 (HV ECU), and a rear wheel bearing replacement done for free under warranty. I have paid for a new set of tires and a new 12 volt battery. It is not well-documented in the maintenance info supplied to the consumer, but these vehicles ought to have soot removed from the throttle body assembly at 60k mile intervals (or shorter). I paid $100 for this, and in the future will consider DIY. 46 mpg lifetime, excluding time with roof loads carried.

With attention paid to tire rotations and inflation pressures, tire replacement intervals of about 50k miles can be expected. DIY engine oil and filter changes, engine and cabin air filter changes can be notable cost savings over the long haul. Document all DIY servicing.

Other than the above, no maintenance or repair expenses to date beyond those scheduled. I intend to drive the car to 300k (assuming gasoline remains readily available!).
