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 1988 Mazda RX-7 is characterized by 13 fire complaints and 11 complaints regarding the gasoline fuel system, alongside 5 complaints for engine and engine cooling. Looking at the subsequent federal record from 1990 to 1995, the generation experienced a volatile complaint trend that peaked in 1993 with 98 complaints and 4 recalls before dropping to 4 complaints by 1995. The 1988 model falls before this recorded arc, but its specific data reveals critical safety concerns that are not mirrored in the general counts of the later years. The data does not specify the root cause for the reported fire or fuel system failures. Because of the high number of fire and fuel system complaints, this is not a good year to buy.
