Is the Mazda MX-5 Miata a Reliable Sports Car?

The Mazda MX-5 Miata has won over countless enthusiasts as one of the most beloved sports cars of all time, but many potential buyers can’t help wondering if this spirited roadster is built to last. Nobody wants ownership of their dream sports car to turn into a nightmare of repair bills, so in this article, our team at John Kennedy Mazda Conshohocken explores the Miata’s reliability data and common problems to help you figure out which model years deliver the best long-term dependability.

Generation-By-Generation Reliability Breakdown

The Mazda MX-5 Miata spans four generations:

• Fourth generation (ND): 2016-present
• Third generation (NC): 2006-2015
• Second generation (NB): 1999-2005
• First generation (NA): 1990-1997

Generally speaking, Mazda MX-5 reliability has gotten better with each new generation, with the current fourth generation dominating reliability rankings. Consumer Reports says the 2024 MX-5 Miata is “much more reliable than the average new car,” while RepairPal hands out a solid 4.0 out of 5.0 reliability rating for the 2025 model, ranking it eighth out of 21 subcompact cars. J.D. Power also gives the ND generation solid marks — the 2019 model had an 86/100 reliability score, while 2023 models scored 76/100.

Over the generations, Mazda has made real improvements to the MX-5’s overall engineering and design, which have contributed to its outstanding reliability.

Common Problems With the Mazda Miata

While Miatas are generally reliable, each generation has its issues that you should know about.

Fourth Generation

Current ND models can develop suspension sagging on one side, transmission issues, power-folding roof problems, fuel pump failures, dashboard light faults, jammed seatbelts, and occasional airbag concerns. The 2016 model year received the most complaints, with 33 reported to the National Highway Traffic Safety Administration. However, the 2024 and 2025 MX-5 models have had only one recall, affecting 12,244 cars, for a traction control light issue.

Third Generation

NC models are known for roof leaks, battery drain, and clutch and gearbox problems, such as grinding.

Second Generation

NB models can experience brake slipping in wet conditions, engine stalling and sudden loss of power, and engine misfires from failing ignition coil packs.

First Generation

Classic NA models might get their manual transmissions stuck in reverse, suffer timing belt failures, or have crankshaft pulley and keyway issues.

Despite the problems mentioned, only 10% of Mazda repairs are considered serious — below the 12% average for all vehicle models.

Maintenance Requirements and Costs

Miatas are surprisingly cheap to maintain. Mazda recommends service every six months or 7,500 miles, whichever comes first. Routine maintenance includes oil changes every 7,500 miles, tire rotations at the same interval, brake checks every 15,000 miles, engine air filter swaps every 30,000 miles, and spark plug replacements every 60,000 miles.

The Miata’s annual maintenance cost averages $429 per year, which is lower than that for many other sports cars, including the Nissan 370Z ($504), Toyota Supra ($561), and Chevrolet Camaro ($585).

Most and Least Reliable Miata Model Years

If you’re shopping for a dependable Miata, the ND generation typically offers the best reliability. However, you’ll want to think twice about the 2016 models due to high complaint numbers; you’re safer betting on the 2018 and newer years if reliability is your primary concern.

The second-generation NB models grab second place for reliability and make great used car picks if you want proven dependability without the latest tech. NC models sit in the middle of the pack reliability-wise, while those original NA models rank lowest — mostly due to issues you’d expect in cars over 25 years old.

Mazda Reliability Data

Mazda is well known for being a reliable brand. Consumer Reports ranks Mazda sixth out of 32 brands for reliability based on data collected from over 300,000 vehicles for the 2000 to 2024 model years. RepairPal ranks Mazda even higher, naming it fifth out of 32 car brands with a 4/5 rating.

When you combine these results with specific Miata reliability data, it’s clear that the Mazda MX-5 Miata is a reliable option if you’re in the market for an everyday sports car. It gives you solid dependability without the premium price tag associated with many performance vehicles.
