1990 Mazda Miata

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1990 Miata.

Body PASSENGER CARTransmission Automatic 4-spd

The 1990 Mazda Miata, a compact passenger car built on Mazda’s lightweight platform, couples its airy, aerodynamic body to a naturally aspirated engine that feeds power through a 4‑speed automatic transmission, delivering EPA‑rated 21/26/23 mpg. One of its most notable specifications is its exceptionally low fuel consumption for the era, a testament to Mazda’s engineering focus on efficiency and handling. In the broader reliability context, the Miata’s owner‑complaint record remained modest throughout the early model years, with only three complaints overall and two recalls, and 1990 sits comfortably near the bottom of the 1990‑2001 complaint spectrum, indicating a relatively robust early model year that set a dependable foundation for the brand’s subsequent evolution.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 1990 model year opens the generation with 3 complaints, 2 recalls, 1 investigation, and 21 TSBs, representing moderate federal activity that sits below the 19921993 peak of 4 complaints annually but matches the volume seen again in 1996, while contrasting with the zero-complaint years of 1991, 1994–1995, and 1998–2000. Its single investigation aligns with 1991 and 1999, though 1995 recorded two investigations, and its two recalls match the 1992–1993 and 2001 levels; notably, 2 of its 3 complaints are crash-related, though the data does not specify root causes. TSB counts remained static at 21 through 1993 before dropping to 9–10 in 1994–1995 and eventually escalating to 104 by 2001, indicating 1990 predates the intensive service documentation of later production. With absolute complaint and recall numbers remaining low and the model predating the complexity indicated by later TSB inflation, the 1990 Miata represents a reasonable acquisition target provided buyers verify completion of its two recalls and review the circumstances of its crash-related complaints.
