As Toyota's least-expensive hybrid, the Prius C seems like a great idea. Similar to its namesake, the C delivers 43 mpg overall, just one mpg less than the larger Prius and a stellar 37 mpg in the city, which is the best of any car we've tested. The C's tiny dimensions and easy parking also make it a natural for urban driving.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for about 500,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2018 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.
