    12V battery

After this happened three or four times I took the car to the dealer, they tested the battery and the battery failed the tests so they replaced the battery. It was outside the warranty so I had to pay."

    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.
