The Mazda Miata, also known as the MX-5, has been a beloved sports car since its introduction in 1989. Known for its lightweight design, nimble handling, and affordable price point, the Miata has garnered a dedicated following among driving enthusiasts. However, like any vehicle with a long production history, some model years are more problematic than others. Understanding which Miata years to avoid can help potential buyers make informed decisions and save themselves from potential headaches down the road.
While the Miata is generally considered a reliable car, certain model years have exhibited more issues than others. These problems can range from minor annoyances to more serious mechanical failures. By identifying these problematic years, buyers can focus their search on more dependable options or at least be prepared for potential issues if they choose to purchase a model from a less reliable year.
| Generation | Years to Avoid |
|---|---|
| NA (1st Gen) | 1990 |
| NB (2nd Gen) | 1999 |
| NC (3rd Gen) | 2006-2008 |
| ND (4th Gen) | 2016 |
First Generation (NA) Miata Issues
The first generation Miata, known as the NA, was produced from 1989 to 1997. While generally reliable, the 1990 model year is often cited as one to avoid. This early production year suffered from several issues that were addressed in later models.
One of the most significant problems with the 1990 Miata was the “short nose crank” issue. This refers to a design flaw in the crankshaft that could lead to the front pulley becoming loose over time. If left unchecked, this problem could result in catastrophic engine failure. While not all 1990 Miatas experienced this issue, it’s a significant enough concern to make many enthusiasts wary of this model year.
Another common problem with early NA Miatas, particularly the 1990 model, was rust. The body panels and frame were more susceptible to corrosion compared to later models. This is especially problematic in areas with harsh winters where road salt is used extensively. Potential buyers should carefully inspect any NA Miata for signs of rust, particularly in the rocker panels, wheel wells, and trunk area.
The 1990 Miata also had issues with its manual transmission. Some owners reported problems with the transmission getting stuck in gear, particularly when shifting from reverse to first. This issue was largely resolved in later model years but remains a concern for the 1990 model.
Despite these issues, it’s worth noting that many 1990 Miatas have been well-maintained and continue to provide enjoyable driving experiences. However, for those seeking the most trouble-free NA Miata experience, it’s generally recommended to look at 1994 and later models, which benefited from several improvements and refinements.
Second Generation (NB) Miata Concerns
The second generation Miata, known as the NB, was produced from 1999 to 2005. While generally considered more refined than its predecessor, the 1999 model year is often cited as one to approach with caution.
One of the primary issues with the 1999 Miata was excessive oil consumption. Many owners reported that their engines would burn through oil at an alarming rate, sometimes requiring a quart to be added every 1,000 miles. This problem was particularly prevalent in the first two years of NB production but was largely resolved by 2001.
Another concern with early NB Miatas, particularly the 1999 model, was the exhaust gas recirculation (EGR) system. The EGR valve could become clogged or stuck, leading to poor engine performance and potentially triggering the check engine light. While this issue can be resolved with cleaning or replacement of the EGR valve, it’s an additional maintenance concern for potential buyers to consider.
The 1999 Miata also experienced some electrical issues. Some owners reported problems with the alternator failing prematurely, leading to battery drain and potential breakdowns. Additionally, there were occasional issues with the power windows and central locking system.
Despite these concerns, the NB generation is generally considered very reliable, especially in later model years. For those interested in a second-generation Miata, focusing on 2001 and later models can help avoid some of the early production issues while still enjoying the improved performance and refinement of the NB platform.
Third Generation (NC) Miata Problems
The third generation Miata, known as the NC, was produced from 2006 to 2015. While this generation brought significant updates to the Miata platform, the early years, particularly 2006 to 2008, are often cited as problematic.
One of the most significant issues with early NC Miatas was transmission failure. Some owners reported problems with the six-speed manual transmission, including difficulty shifting and premature wear. In extreme cases, this could lead to complete transmission failure, requiring expensive repairs or replacement.
Another common problem with early NC Miatas was oil consumption. Similar to the early NB models, some NC engines would burn through oil at an unusually high rate. This issue was particularly prevalent in the 2.0-liter engine used in the 2006-2008 models.
The NC generation also introduced a power retractable hardtop (PRHT) option. While this feature was popular, early models (2006-2008) sometimes experienced issues with the roof mechanism. Problems could range from slow operation to complete failure of the roof to open or close.
Some NC owners have reported suspension issues, particularly with the front control arms. This could lead to excessive tire wear and affect the car’s handling characteristics. While not a universal problem, it’s something potential buyers should be aware of, especially when looking at higher mileage examples.
Despite these issues, the NC generation brought significant improvements in terms of power, refinement, and safety features. For those interested in a third-generation Miata, focusing on 2009 and later models can help avoid some of the early production problems while still enjoying the benefits of the NC platform.
Fourth Generation (ND) Miata Considerations
The fourth and current generation Miata, known as the ND, was introduced in 2016. While generally well-received, the 2016 model year has some issues that potential buyers should be aware of.
The most significant problem with the 2016 ND Miata was transmission failure. Some owners reported issues with the six-speed manual transmission, including premature wear and, in some cases, complete failure. Mazda acknowledged this issue and made improvements to the transmission for subsequent model years.
Another concern with early ND Miatas was engine reliability. Some 2016 models experienced issues with the Skyactiv-G engine, including excessive oil consumption and, in rare cases, engine failure. These problems were largely addressed in later model years through updates to the engine design and manufacturing process.
Some 2016 ND owners have reported issues with the infotainment system, including freezing screens and connectivity problems. While not a mechanical issue, this can be a source of frustration for owners who rely on these features.
Despite these concerns, the ND generation has been widely praised for its lightweight design, improved performance, and modern features. For those interested in a fourth-generation Miata, focusing on 2017 and later models can help avoid some of the early production issues while still enjoying the benefits of the latest Miata platform.
