Kia Niro

Thanks to its high stance, conservative styling, and a more normal, traditional-acting automatic transmission, the Kia Niro is a genre-splitting hybrid that combines fuel economy with versatility. It uses the same drivetrain as its sibling hybrid -- the Hyundai Ioniq -- and also suffers from some of that car's shortcomings. When compared with conventional wagons and small SUVs, the Niro's 43 mpg overall is impressive.

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 over 300,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2021 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.
