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 2024 vehicles are holding up in 20
potential trouble spots, ranging from the engine, transmission, electric motor, EV charging, and
brakes to power equipment and the electrical accessories.
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.
