Specific symptoms reported on the 1993 Mazda RX-7
Recalls 3
Service brakes, hydraulic: power assist: vacuum: hoses, lines/piping, and fittings
- What is wrong
- 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.
- Risk
- 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.
Recall number 96V149000 · Recall details
Fuel system, gasoline: delivery: hoses, lines/piping, and fittings
- What is wrong
- 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.
- Risk
- 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.
Recall number 95V069000 · Recall details
Engine and engine cooling: cooling system
- What is wrong
- 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.
- Risk
- 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.

Should this occur the engine coolant could leak directly on top of the engine. The consumer stated this recall failed. *nlm the recall was partially completed. Both required replacement of the cooling system including the water pump which was not done because the vehicle lost the water pump on the road. *scc
Oil line to turbo's collapsed causing the inner coolers to be flooded with oil. This was caused by the apex seal coming off in the rotary tube which caused the compression levels to drop. This damage costs me in excess $10000 and happened at 30000 miles. An investigation is currently under way.
Fuel pustation dampner spontaneously failed and began spraying a 6" stream of fuel under the upper intake manifold. Thank god I noticed the smell or this would have been a very nasty engine fire. The fuel leaks down from the fpd and runs off onto the turbo assembly. Scc ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis***770788
I noticed white smoke coming into the car while driving to work. I stopped the car right away and opened the hood to see the back of the engine on fire. I put the fire out with a fire extinguisher and had the car towed to a mazda rotary engine specialist. I was informed by the mechanic that the fire was a result of the faulty factory fuel line and the fuel injection system, which are a well known problem by mazda mechanics. The mechanic told me that these fires happen quite frequently in 1993-1996 rx-7's as well as in the prior body style. I could have been seriously injured from this incident, and my car now needs over $3,000 worth of repairs, all due to a known problem that has never been recalled. Please help me. Dt
