What Is a Mazda Miata? — Definition & Overview
The Mazda Miata, officially known as the Mazda MX-5 (or Eunos Roadster in some markets), is a lightweight, rear-wheel-drive two-seat convertible sports car that has been in continuous production since 1989. It is widely recognized as the world’s best-selling two-seat convertible sports car, a title it has held for decades according to the Guinness World Records.
The Miata was born from Mazda’s desire to revive the spirit of classic British and Italian roadsters — lightweight, nimble, open-top motoring at an affordable price. Unlike its European predecessors, the Miata combined Japanese reliability with driver-focused fun, creating a winning formula that has endured for over three decades.
Understanding the Miata years to avoid is critical before making a purchase. Not all model years were created equal — some suffered from design flaws, reliability issues, or costly mechanical defects that make them risky second-hand buys. This guide gives you every fact you need.
The 4 Generations of Mazda Miata — A Complete Overview
Before diving into specific Miata years to avoid, it helps to understand how the car evolved across its four distinct generations. Each generation brought new engineering, new problems, and new highlights.
Classic roadster. Lightweight, simple. Rust-prone but iconic.
More refined, slightly heavier. Some engine problems.
Bigger, more powerful. Hardtop option added. Mixed reliability early.
Back to lightweight roots. Modern tech. Best balance yet.
Each generation had different engine options, body styles, and feature sets. The key information for used car buyers is how reliability varied across these generations — and which specific years within each are worth pursuing or skipping entirely.
⚠️ Miata Years to Avoid — The Worst Model Years Ranked
Based on NHTSA complaints, CarComplaints data, owner forums, and real-world mechanic feedback, the following Mazda Miata years are best avoided. These model years have documented histories of mechanical failures, expensive repairs, or widespread owner dissatisfaction.
1990 Mazda Miata — First Year, Many Bugs
The very first production year. While historically significant, it was plagued by air conditioning compressor failures, electrical system problems, and fuel pump issues. Many owners had to replace the AC system multiple times. At nearly 35 years old, finding pristine, unmodified examples is also nearly impossible.
1991 Mazda Miata — Carried Over Problems
The 1991 retained many first-year issues. Crankshaft thrust bearing failures began emerging on early 1.6L engines. Rust on door bottoms, sills, and subframes is a serious concern on surviving examples. More complaints on record than the later NA models.
1999 Mazda Miata — Thrust Bearing Nightmare
One of the most problematic Miata years ever. The 1999 NB-generation debut brought with it a well-documented thrust bearing defect on the 1.8L engine, causing catastrophic engine failure often before 40,000 miles. This was a factory defect linked to incorrect parts installed during assembly. Engines would fail with little warning.
2000–2001 Mazda Miata — 20+ NHTSA Complaints Each
Both the 2000 and 2001 model years each registered over 20 complaints with the NHTSA. The 2001 was notably affected by a batch of cars shipped with wrong thrust bearing parts, echoing the 1999 disaster. Transmission concerns and electrical gremlins were also commonly reported across both years.
1996 Mazda Miata — OBD-II Transition Year
The 1996 model was a transitional year when Mazda switched to OBD-II emissions diagnostics. The transition caused frequent check engine lights, emissions test failures, and difficulty diagnosing actual problems. While not catastrophically unreliable, it’s a headache-prone year for smog compliance.
2007–2008 Mazda Miata (NC) — Electrical & Paint Failures
Early NC-generation models were beset by electrical system failures, including wiring connection faults and unexpected battery drain. The paint quality was notoriously poor, with peeling and premature oxidation reported widely. Battery discharge without warning was a common complaint. Repair costs on these NC electrics can be significant.
2016 Mazda Miata (ND) — First-Year Transmission Recall
The brand-new fourth-generation ND launched in 2016 with a confirmed manual transmission recall in the US market. Infotainment system glitches and intermittent keyless entry failures were also reported. The ND platform itself is excellent, but the debut year had typical first-year teething issues. Later ND years are much better.
✅ Best Miata Years to Buy — Top Picks by Generation
Now for the good news: the Mazda Miata has many outstanding model years that offer near-bulletproof reliability, engaging driving dynamics, and excellent long-term value. Here are the best Miata years across each generation:
🏆 Best NA Years: 1994 & 1997
1994 is frequently cited as the best first-generation Miata. Mazda addressed early reliability issues, added a passenger airbag, and refined the suspension. The 1994 is considered the sweet spot of the NA — reliable, fun, and safe. 1995 added ABS brakes, and 1997 brought a final round of refinements before the generation ended.
🏆 Best NB Years: 2003–2005
After the rocky 1999–2001 debut, the NB generation settled down considerably by 2003. The 2003–2005 models benefited from corrected thrust bearings, improved electrical systems, and the popular Mazdaspeed Miata (2004) variant with a turbocharged engine. These are excellent used buys with a well-documented reliability record.
🏆 Best NC Years: 2009–2012 & 2014–2015
Once Mazda sorted out the early NC teething problems, the 2009+ models represent a much-improved package. The 2009 received a notable update with a new 2.0L engine (167 hp), improved suspension tuning, and better quality control. The Power Retractable Hard Top (PRHT) option is a notable feature. The 2014–2015 models are excellent final-year NC options before the ND launched.
🏆 Best ND Years: 2019–2024
The 2019 ND refresh brought a power bump to 181 hp, improved suspension, and squashed most of the 2016–2018 first-year issues. The 2024 model (ND3) added a larger 8.8-inch infotainment system, adaptive cruise control, and rear automatic emergency braking — representing the most complete Miata ever built. If budget allows, a 2019+ ND is the best used Miata you can buy today.

🔧 Common Mazda Miata Problems by Generation
Understanding what goes wrong and why on each Miata generation is essential when evaluating a used purchase. Here are the most frequently reported issues:
NA Generation (1990–1997) — Rust & First-Gen Issues
- Rust: The most serious long-term threat. Check rocker panels, subframes, floor pans, door bottoms, and the rear subframe area. The NA rusts badly in snowy/salt-heavy climates.
- Coolant system leaks: The 1990–1991 models had water plug leaks and engine overheating.
- Crankshaft thrust bearing wear on 1.6L engines, especially 1990–1991.
- AC compressor failure — extremely common on 1990 models.
- Leaking soft tops — weatherstripping degrades over time.
NB Generation (1999–2005) — Thrust Bearing & Paint
- Thrust bearing failure (1998–2001): Engines often failed before 40,000 miles due to incorrect bearing installation at the factory. Always check crankshaft end-play.
- Oil consumption — excessive oil burning reported on 1999–2001 engines.
- Paint peeling — NB models were notorious for lackluster paint adhesion, leading to peeling and rust underneath.
- Electrical gremlins — battery drain, intermittent power window failures.
NC Generation (2006–2015) — Electrical & Weight
- Battery drain (especially 2007–2008): Unexpected battery discharge due to wiring faults.

❓ Frequently Asked Questions — Miata Years to Avoid
Here are answers to the most commonly asked questions about Miata years to avoid, reliability, safety, and buying decisions.
The years most commonly recommended to avoid are 1990, 1991, 1999, 2000, 2001, 2002, 2007, 2008, and with caution, 2016. These years have documented histories of thrust bearing failures, electrical problems, paint defects, or significant NHTSA complaint volumes. If you’re considering any of these years, have a full pre-purchase inspection by a Miata-knowledgeable mechanic first.
For modern reliability, the 2019–2024 ND2/ND3 models are the most reliable Miatas ever built. For classic affordability, the 1994–1997 NA or 2003–2005 NB models offer excellent value. The 2009–2015 NC is a great middle-ground with modern features at lower prices.
The Miata’s appeal comes from its near-perfect weight distribution (50/50 front/rear), incredibly communicative steering, and lightweight chassis that makes even modest power feel exciting. Car enthusiasts often say it’s not about raw speed — it’s about how the car makes you feel. Many experienced drivers argue it’s the most satisfying car to drive on a winding road, regardless of price class.
Absolutely, yes. A well-chosen used Miata offers tremendous value. A 2009–2015 NC can be found for $8,000–$15,000 and will reliably last hundreds of thousands of miles. A used 2019–2021 ND2 can be found for $18,000–$26,000 and represents one of the best sports car values available. Just avoid the problematic years listed in this guide and get a proper inspection.
These are the four generations of the Mazda Miata: NA (1990–1997) is the original classic, lightest, and most “pure” roadster; NB (1999–2005) is a subtle refinement with more power; NC (2006–2015) is larger, heavier, and more comfortable with a hardtop option; ND (2016–present) returns to the lightweight philosophy with modern technology. Each generation has specific years to avoid and recommended years — see the full guide above.
A well-maintained Mazda Miata can comfortably reach 150,000–200,000 miles, and many owners report engines lasting well beyond that. The key factors are: regular oil changes, avoiding the problematic model years, addressing rust proactively, and not abusing the drivetrain. The MX-5 engine is mechanically simple and robust when properly cared for.
Surface rust on body panels is manageable and common. However, structural rust on subframes, floor pans, and sill sections is potentially a deal-breaker. Structural rust repair can cost $2,000–$8,000+ depending on severity. Always get a NA or NB Miata up on a lift for inspection. Cars from dry climates (Arizona, California) are far safer bets than those from snow-belt states.
The thrust bearing problem primarily affects 1999–2001 NB Miatas. It was caused by incorrect thrust bearings being installed at the factory. The thrust bearing controls crankshaft lateral movement. When it fails, the crankshaft can shift and damage the entire engine — often catastrophically and without warning. A mechanic can check crankshaft end-play in minutes. Any reading over 0.012 inches is a red flag. Always check this before buying any 1999–2001 NB Miata.
During a test drive: listen for engine knocking or rattling (thrust bearing warning), feel for vibration in steering (worn bushings/tyres), test all gear shifts smoothly, put the top down and back up fully, test all electrics (windows, climate, stereo), and smell for burning oil or rubber. Drive over bumps to check suspension health. If anything feels off — walk away or insist on a full inspection.
The Miata can work as a daily driver if you’re a single person or a couple with minimal cargo needs. It’s fuel efficient (30+ MPG highway), relatively comfortable for a sports car, and genuinely enjoyable to commute in. The limitations are the tiny trunk, only 2 seats, and reduced practicality in heavy rain or snow (especially soft-top models). For dry-climate daily driving, it’s an excellent and underrated choice.
