1993 Mazda Rx-7 problems
The Mazda RX-7 is a front-engine, rear-wheel-drive, rotary engine-powered sports car that was manufactured and marketed by Mazda from 1978 until 2002 across three generations, all of which made use of a compact, lightweight Wankel rotary engine.
The first-generation RX-7, sometimes referred to as the SA (early) and FB (late), is a two-seater 2-door hatchback coupé. It featured a 12A carbureted rotary engine as well as the option for a 13B rotary engine with electronic fuel injection in later years.
The second-generation RX-7, sometimes referred to as the FC, was offered as a 2-seater coupé with a 2+2 option available in some markets, as well as in a convertible body style. This was powered by the 13B rotary engine, offered in naturally aspirated or turbocharged forms.
The third-generation RX-7, sometimes referred to as the FD, was offered a 2+2-seater coupé with a limited run of a 2-seater option. Some markets were only available as a 2-seater. It featured a sequentially-turbocharged 13B REW engine.
More than 800,000 RX-7s were manufactured over its lifetime.

Common Problems with the Mazda RX-7 1993
The Mazda RX-7 1993 is a beloved classic sports car, but like any vehicle, it has its share of common issues that owners may encounter. Here are some of the most frequently reported problems with the Mazda RX-7 1993, based on complaints from owners of this car.
- Oil Leaks
One of the most common problems with the Mazda RX-7 1993 is oil leaks. These leaks can occur at the rear stationary gear seal and O-ring, which can lead to significant oil loss and potential engine damage if not addressed promptly.
- Turbo Failure
The Mazda RX-7 1993 is known for its turbocharged engine, but this system can also be prone to failure. Malfunctioning turbos may be caused by problems with the RX-7's complex array of vacuum lines and solenoid valves. High under-hood temperatures can also contribute to turbo failure, making it essential to keep the engine cool and well-maintained.
- Engine Maintenance
The rotary engine in the Mazda RX-7 1993 requires unique maintenance procedures that can be challenging for some owners. For example, the engine's seals can benefit from the use of a fuel lubricant with every tankful of gasoline, and re-torqueing the engine tension bolts can help keep seals tight. Additionally, using premium fuel and promptly replacing dirty fuel filters can help prevent detonation and engine damage.
- Cooling System
The cooling system in the Mazda RX-7 1993 can also be prone to issues, with the front ("pre-cat") catalytic converter often clogging and causing engine damage. Installing a more efficient aftermarket aluminum radiator and promptly addressing any leaks or issues with the cooling system can help prevent engine damage and ensure the car runs smoothly.
- Interior Issues
The interior of the Mazda RX-7 1993 can also be prone to issues, with the coin collector cover and compartment lid being particularly problematic. The spring inside the compartment lid often breaks, and the coin collector cover can become weak over time, causing it to rip off. These issues can be addressed with replacement parts or repairs, but they can be frustrating for owners
- Speedometer Cluster
The speedometer cluster in the Mazda RX-7 1993 can also be prone to issues, with the rev counter needle sometimes not sitting correctly on the zero mark. This issue can be addressed with a replacement part or repair, but it can be frustrating for owners
- Door Handles
The door handles in the Mazda RX-7 1993 can also be problematic, with the mechanisms often breaking and causing the handle to become floppy. This issue can be addressed with replacement parts, but it is essential to address it promptly to prevent further damage
In summary, the Mazda RX-7 1993 is a beloved classic sports car, but like any vehicle, it has its share of common issues that owners may encounter. Oil leaks, turbo failure, engine maintenance, cooling system issues, interior problems, speedometer cluster issues, and door handle problems are all common issues that owners of this car may encounter. Regular maintenance and prompt attention to any issues can help ensure the car runs smoothly and lasts for many years to come.
Why is RX-7 engine bad?
Rotary engines are known for incomplete combustion, oil consumption, and high emissions, relegating the RX-7 to project car status rather than daily drivers. As Hagerty reports, somewhere around 13,879 third-generation RX-7s were sold in the U.S. between 1993 and 1995.
Why is the Mazda RX-7 banned in the US?
Any Mazda RX-7 produced after 1995 is not allowed or is banned in the United States. This is because of the left-hand driving configuration of the vehicle. This means that if you want to own one, you have a couple of options. One is to find a used RX-7 in the United States that is a 1995 year model or older.
How many 1993 rx7 were made?
13,879 cars
All told, approximately 13,879 cars were produced for the US in total throughout the three-year production run.

ENGINE AND ENGINE COOLING PROBLEM
- Date Of Incident: 1999-11-16
- VIN: JM1FD3315P0
- Components: ENGINE AND ENGINE COOLING
- Summary: ON 11/16/99 I WAS DRIVING ABOUT 40 MPH AND MY ENGINE CUT OUT. I DROVE THE CAR TO CLASSIC MOTOR CARS. THEY CONTACTED ME TO LET ME KNOW THAT MY CAR HAD LOST COMPRESSION AND THAT THE ENGINE WOULD HAVE TO BE REPLACED. I CONTACTED MAZDA CUSTOMER RELATIONS TO DETERMINE WHAT RECALLS HAD BEEN APPLIED TO MY CAR. THEY CONFIRMED THAT MAZDA RECALL #60504 AND #65609 HAD BEEN APPLIED. I ASKED ABOUT MAZDA RECALL #54407 AND [XXX] STATED THAT I WAS NOT NOTIFIED OF THAT RECALL BECAUSE ACCORDING TO THE COMPUTER, MY CAR DID NOT NEED THE RECALL. UPON FURTHER INVESTIGATION HE IDENTIFIED THE VIN #JM1FD33**P0200001 THROUGH JM1FD33**R0302076 SHOULD HAVE BEEN NOTIFIED OF THAT RECALL. SINCE MY VIN #[XXX] FALLS WITHIN THAT RANGE, I ASKED WHY MY CAR SHOULDN'T BE CONSIDERED TO HAVE THE RECALL. HE SAID HE DIDN'T KNOW. IT SEEMS THAT THERE IS A COMPUTER PROBLEM. I SHOULD HAVE BEEN NOTIFIED AND HAD THE RECALL WORK DONE. IN SPECIFIC, I UNDERSTAND THAT THIS RECALL WORK PREVENTS THE ENGINE COMPARTMENT FROM CATCHING FIRE. SINCE MY VEHICLE WAS NOT INCLUDED IN THIS RECALL, IN ERROR, I WOULD SUSPECT THERE ARE MANY OTHERS THAT SHOULD HAVE BEEN RECALLED, THAT WERE NOT. THIS NEGLIGENCE IS A POTENTIAL THREAT TO ME, MY FAMILY AND MY PROPERTY. ALSO, I BELIEVE THAT SINCE MY CAR WASN'T IDENTIFIED TO HAVE THE RECALL WORK DONE, THAT THIS CONTRIBUTED TO THE DETERIORATION OF THE APEX SEALS IN MY ENGINE. ANY ENGINE SHOULD LAST LONGER THAN 49,800 MILES. UPON CONTACTING MAZDA, THE DM HAS AGREED TO OFFER $1,000 TOWARDS THE REPLACEMENT OF THE ENGINE, BUT THEY DO NOT FEEL THAT THIS IS A DEFECT. I FEEL THAT SINCE WE ARE NOT IDENTIFIED IN THEIR COMPUTER AS RECALL CANDIDATES, AND SINCE WE WERE NOT NOTIFIED TO HAVE THE RECALL WORK DONE, AND SINCE WE DID NOT HAVE THE RECALL WORK DONE, THE APEX SEALS HAVE DETERIORATED AS A RESULT OF THE HEAT GENERATED INSIDE THE ENGINE THAT CAUSES FIRES IN THE ENGINE COMPARTMENT WITHOUT WARNING. I WOULD LIKE FOR YOUR AGENCY TO ASSIST ME BY CONFIRMING THIS. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

1993 Mazda Rx-7 recalls
The National Highway Traffic Safety Administration (NHTSA) has issued 4 recalls for different components of the 1993 Mazda Rx-7.
- Manufacturer: MAZDA NORTH AMERICAN OPERATIONS
- Components: LATCHES/LOCKS/LINKAGES:HOOD:LATCH
- Summary: EQUIPMENT DESCRIPTION: MAZDA SPEED RESINOUS HOODS, DESIGNED AND SOLD AS ACCESSORY PARTS FOR MODEL YEAR 1992-1995 RX7 VEHICLES, MANUFACTURED BETWEEN JUNE 1, 1997, THROUGH SEPTEMBER 19, 2000.
- Consequence: A HOOK ON A HOOD STRIKER FOR THE RESINOUS HOOD MAY SEPARATE FROM A BASE PLATE AT THE WELDED PORTION DUE TO INSUFFICIENT WELDING STRENGTH. THE HOOD MAY SUDDENLY OPEN DURING OPERATION, LOSING FRONT VISIBILITY, POSSIBLY RESULTING IN A VEHICLE CRASH.
- Remedy: MAZDA WILL NOTIFY THE RX7 VEHICLE CUSTOMERS TO BRING THEIR VEHICLE TO A MAZDA DEALER TO HAVE THE HOOD STRIKER REPLACED WITH A MODIFIED ONE.
- Manufacturer: MAZDA (NORTH AMERICA),INC
- Components: SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM:HOSES, LINES/PIPING, AND FITTINGS
- Summary: OIL MIST CONTAINED IN THE ENGINE INTAKE AIR CAN COLLECT OVER TIME IN THE BRAKE VACUUM CHECK VALVE PREVENTING THE CHECK VALVE FROM OPENING AT THE SPECIFIED PRESSURE REDUCING POWER ASSIST TO THE BRAKES.
- Consequence: BRAKE PERFORMANCE CAN BE DIMINISHED INCREASING THE RISK OF A VEHICLE ACCIDENT.
- Remedy: DEALERS WILL REPLACE TWO VACUUM HOSES, INCLUDING THE CHECK VALVE, WITH MODIFIED HOSES.
- Manufacturer: MAZDA (NORTH AMERICA),INC
- Components: FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS
- Summary: RESIDUAL ENGINE HEAT CAN CAUSE PREMATURE DETERIORATION OF THE FUEL HOSE CAUSING THE HOSE TO LEAK. ALSO, REMOVING AND REINSTALLING THE DETERIORATED FUEL HOSES INCREASES THE LIKELIHOOD OF A LEAK.
- Consequence: THIS CONDITION CAN RESULT IN AN ENGINE COMPARTMENT FIRE.
- Remedy: DEALERS WILL INSTALL AN ADDITIONAL CONTROL UNIT FOR THE ELECTRIC COOLING FAN. THE FAN WILL THEN ACTIVATE AFTER THE ENGINE IS TURNED OFF WHEN THE COOLANT EXCEEDS A SPECIFIED TEMPERATURE. THE FUEL HOSES WILL ALSO BE REPLACED WITH REVISED HOSES.
- Manufacturer: MAZDA (NORTH AMERICA),INC
- Components: ENGINE AND ENGINE COOLING:COOLING SYSTEM
- Summary: THE RADIATOR CAP PRESSURE RELIEF VALVE RELEASE PRESSURE IS SET TOO HIGH. THIS CAN CAUSE THE COOLANT TO REACH TEMPERATURES THAT EXCEED THE THERMAL DESIGN LIMITS OF SOME COMPONENTS OF THE COOLANT SYSTEM. SHOULD THIS OCCUR, ENGINE COOLANT CAN LEAK COLLECT ON TOP OF THE ENGINE.
- Consequence: IF ENGINE COOLANT LEAKS ONTO THE HOT ENGINE EXHAUST MANIFOLD FROM THE TOP OF THE ENGINE, AN ENGINE COMPARTMENT FIRE CAN RESULT.
- Remedy: DEALERS WILL INSPECT THE VEHICLES AND IF ANY VEHICLE EXHIBITS COOLANT LEAKAGE OR IF THE COOLANT LEVEL HAS DROPPED TO THE POINT WHERE THE COOLANT LOSS WOULD BE SUFFICIENT TO TRIGGER THE COOLANT LEVEL WARNING SYSTEM, COMPONENTS POTENTIALLY SUBJECT TO DETERIORATION FROM OVERHEATING WOULD BE REPLACED. THESE PARTS INCLUDE THE WATER PUMP BEARING HOUSING, THE WATER LEVEL SENSOR AND RADIATOR UPPER HOSE, THE THERMOSTAT GASKET, AND ALL WATER HOSES LOCATED ABOVE THE ENGINE. IN ADDITION, ALL VEHICLES IN WHICH THOSE COMPONENTS ARE REPLACED WOULD ALSO HAVE THE COOLING SYSTEM AND OTHER SYSTEMS THAT CARRY FLAMMABLE LIQUIDS CHECKED TO MAKE CERTAIN THAT ENGINE OVERHEATING HAD NOT CAUSED ANY PROBLEMS IN THOSE SYSTEMS. ANY IDENTIFIED PROBLEMS WILL BE REPAIRED. THE RADIATOR CAP, FILLER CAP, AND FILLER CAP BODY OF ALL RECALLED VEHICLES WILL BE REPLACED BY NEWLY DESIGNED PARTS.

The car is really fast and enjoyable to drive!!

I really didn't know much about this car until my friend started talking about it and how he was going to get one. The first time I saw it, I fell in love. When he decided to sell it because he wanted a 66 Mustang Fastback, I jumped at the chance to own it. It has a 99 Japanese spec motor with less than 10,000 miles and I absolutely adore it. I take great care of this car, it's like my baby.
-
So glad to hear that the car has been excellent! It's always great to have a reliable vehicle that you can count on. And who knows, maybe you'll keep it forever!
-
I remember seeing one in a magazine and wanting it so badly. However, it took me eight more years to finally be able to afford and justify buying one. Luckily, I found a low-mileage, multi-owner Touring model that I absolutely adore. Honestly, I can't think of any other vehicle I'd rather own, except maybe a Daytona coupe.
-
This is the best car I've ever driven! :)

Mohamed Pacocha 2024-08-03
I had some issues with flooding and poor fuel economy, but overall my experience with the car was positive. I would consider buying it again in the future, but only when I have the financial means to address any potential problems. Unfortunately, I did have to spend $1,200 NZ just to have it looked at by a mechanic. I ended up selling it to a car dealer. I would caution against purchasing a red Batmobile with black 17 inch Enkeii rims, as this particular car may have had a transmission change. However, I do not regret my time with the car.
