2001 Toyota Prius 4dr Sedan (1.5L 4cyl gas/electric hybrid CVT)
I have had relatively few problems and the trouble with the car is that after 100K the service departments do not care about the car and have thrice given me careless and wrong diagnosis of the troubles I have had with the battery depleting while I am driving. It will simply stop in the middle of a journey. It's worse in city traffic. The other issue to my mind is that the mileage is no great shakes. I get maximum 50 miles per gallon. I remember in the 70's that many cars were small and getting gas mileage that was over 40mpg. So young people- don't be taken in by the hype. Get a smaller car.
I love that there is no fuel consumption while idling, and that the car runs as quiet as a top of the line luxury car.
Stop increasing its size - you'll save us more mph.
