I had a 2011 gen 3 Prius. Followed regular oil change and transmission fluid change. Clocked 220000 miles with no trouble at all. The only service outside the routine was a set of disc brakes around 120000 miles and brake line change due to corrosion (I live by the sea...Lots of salty road). The best car I have owned so far, always started in the morning without fail. Previously owned Fiat Punto and Audi A4 that spent more time in garage than on the road. Changed the Prius to a Lexus IS300h.
