What Problems Does the 1991 Mazda RX-7 Have?
The 1991 Mazda RX-7, like many rotary-powered cars, has specific reliability concerns that owners should be aware of. The most critical is the engine's apex seals. These seals are crucial for compression, and wear can lead to loss of power, hard starting, and eventual engine failure. This is often exacerbated by poor maintenance, infrequent oil changes, or overheating. Overheating itself is a common issue for RX-7s, often stemming from aging radiators, hoses, or water pumps. The rotary engine also tends to consume oil as part of its design, so regular checks and top-offs are essential. Neglecting this can lead to catastrophic engine damage.
Fuel injectors on higher mileage examples can become clogged, affecting performance and fuel economy. The ignition system, including coils and spark plugs, can also require more frequent attention than on a piston engine. For the 1991 model year specifically within the FC generation, issues can include:
Rust: Being a car from the early 90s, rust is a significant concern, particularly around the wheel arches, rocker panels, and underbody. Thorough inspections are crucial for any potential buyer.
Electrical Gremlins: Like many cars of this era, the RX-7 can suffer from aging wiring harnesses and connectors, leading to intermittent issues with lights, gauges, or other accessories.
Air Conditioning: The AC system components can degrade over time, leading to a lack of cooling.
Transmission Issues: While generally robust, some owners report clutch wear or manual transmission synchro issues on high-mileage examples.
There were no major widespread recalls specifically targeting the 1991 model year for catastrophic failures. However, it's crucial to note that the longevity and reliability of any 1991 RX-7 heavily depend on its maintenance history and how it has been driven. A well-maintained car with regular oil changes, proper cooling system upkeep, and careful driving can still be a joy, while a neglected one can become a money pit.

Anti-lock brakes (ABS) were an available option on some models, particularly the Turbo II and GXL trims, providing improved braking control in emergency situations. Cruise control was also an option on many models. The defining visual tech feature was undoubtedly the iconic pop-up headlights, a hallmark of 80s and early 90s sports car design.
Safety features were basic. Seatbelts were standard, and the car was built with a generally robust chassis for its time. However, modern safety technologies like airbags (driver-side airbag might have been optional or introduced later in the generation, but not standard on all 1991 models), traction control, or extensive driver-assistance systems were not present. Crash-test ratings for vehicles from this era are not readily available or comparable to modern testing protocols (like NHTSA or IIHS) which were less rigorous or non-existent for many cars of that vintage. Therefore, a definitive crash-test rating for the 1991 RX-7 is difficult to ascertain and would not reflect contemporary safety expectations.
