1991 Mazda Protege

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 Protege.

Body PASSENGER CARTransmission Automatic 4-spd

The 1991 Mazda Protege is a passenger car equipped with an automatic 4-speed transmission and EPA-rated fuel economy of 19 city/24 highway/21 combined mpg. Within the 1990–2006 Protege complaint history, the 1991 model’s 58 owner complaints place it above the 1990 low of 41 but well below the 1995 peak of 206, making it one of the less-reported years in the record. Its leading complaint area is seat belts, and it carries one recall, so a researcher should treat those two items as the defining reliability touchpoints for this model year.

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 1991 Mazda Protege recorded 58 complaints, one recall, and three investigations, which is higher than the 41 complaints, one recall, and two investigations seen in 1990 but lower than the 68 complaints, one recall, and two investigations reported for 1992. Across the 1990‑2003 generation, complaints show a steady upward trend, rising from 41 in 1990 to a peak of 206 in 1995 before fluctuating at elevated levels through the early 2000s. Recall frequency remains constant at one per year from 1990 through 1994, then increases markedly after 1995, indicating that 1991 falls within the low‑recall early period of the generation. Investigations also rise slightly in 1991 relative to its immediate neighbors, mirroring the early‑stage increase in reported issues. Overall, the 1991 model sits on the lower end of the complaint curve compared with later years, suggesting it is a reasonably sound choice, though the 1990 model offers marginally fewer complaints.
