1993 Mazda RX-7

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1993 RX-7.

Transmission Automatic 4-spd

The 1993 Mazda RX-7, fitted with a 4-speed automatic transmission and EPA-rated at 16 city/22 highway/18 combined mpg, represents the model’s most problematic year in the 1990–1995 range, with 98 total owner complaints concentrated in the Engine & Engine Cooling area and four recalls. This peak in complaints stands in stark contrast to the 1995 model, which recorded only four complaints, underscoring the 1993’s position as the least reliable variant of this generation for researchers to note.

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 1993 Mazda RX-7 represents a dramatic outlier in this generation’s federal record, with 98 complaints—more than triple the 30 filed in 1990 and far above the zero recorded for 1992—while recalls jumped to 4 and TSBs surged to 24 against the single-digit levels seen from 1990 through 1992. Across the generation, the data traces a low baseline in the early years, a sharp 1993 spike, and then a rapid retreat to 19 complaints in 1994 and just 4 in 1995, placing the target year at the peak of an anomalous arc. Complaints clustered heavily in Engine & Engine Cooling (38), Fuel System, Gasoline (18), and Electrical System (16), alongside 29 fire complaints and 4 crash complaints, though the data does not specify root causes. Because 1993 concentrates the generation’s highest complaint volume by a wide margin and ties for the most recalls, it presents the weakest risk profile in this range; buyers would be better served by a 1994 or 1995 model with markedly fewer complaints.
