The MX-5 Miata is fun to drive, with extraordinary handling and a slick powertrain. The interior is nicely finished and the manual convertible top is simple to operate from behind the wheel. The ride is comfortable for a sports car, although noise levels and cramped quarters make long trips tiresome.

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.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2009 Mazda MX-5 Miata owners. The owner comments describe problems respondents experienced with this vehicle.

Body Integrity

Squeaks, rattles, wind noises, loose or cracked seals and/or weather-stripping, air and water leaks.

What Owners Say

Seals and/or weather-stripping

"Convertible top has a flaw that creates a rip in the top when it is put up and down over time"

Anonymous, CO (2009 Mazda MX-5 Miata Sport 2.0-L 4 Cyl)

Robert M., VA (2009 Mazda MX-5 Miata Grand Touring 2.0-L 4 Cyl)

"Dealer solved it by tightening the latch mechanism on the convertible hard-top"

Mike T., TX (2009 Mazda MX-5 Miata Grand Touring 2.0-L 4 Cyl)

Drive System

Driveshaft or axle, CV joint, differential, transfer case, 4WD/AWD components, driveline vibration, traction control, electronic stability control (ESC), electrical failure.

What Owners Say

Differential

"oil seal leaked, when oil was too low the unit failed completely requiring a tow to shop and replacement with a new unit"

Greg C., IA (2009 Mazda MX-5 Miata Grand Touring 2.0-L 4 Cyl)
