The Miata is a fun-to-drive, low-slung little roadster, with pinpoint handling, instant power delivery, and a crisp manual gearbox. Excellent fuel economy is an extra bonus. While it remains very tight, the cabin has grown a little more livable over the years. The ride is surprisingly tolerable, but cabin noise can grow wearying on long cruises.

Reliability

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, our reliability history charts give you a rundown on how used vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system.

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 420,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2019 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.
