MAZDA 1994 RX7 FD3S PULSATION DAMPENER FAILURE. CAUSED LOSS OF FUEL AND DAMAGE TO WIRE HARNESS. THE FUEL LEAKED ONTO AND INTO THE WIRE HARNESS AND CAUSED THE HARNESS TO BECOME SATURATED, DAMP AND BRITTLE.

I CAME EXTREMELY CLOSE TO AN ENGINE FIRE. MY ENGINE BAY WAS SOAKED WITH FUEL. NOW HALF THE ENGINE HAS TO BE TAKEN OUT IN ORDER TO FIX THIS PROBLEM. I SHOULDNT HAVE TO FIX THIS. THE RX-7 HAS BEEN AROUND LONG ENOUGH TO BE ABLE TO COME UP WITH A SUITABLE FIX FOR THIS PROBLEM. I DONT WANT THIS TO HAPPEN AGAIN. IT IS VERY DANGEROUS. WHY IS THIS NOT ON THE FUEL SYSTEM RECALL FIX LIST. IT IS KNOW TO FAIL.*AK

Owner report 761191 · 2002-04-25 (April 25, 2002)
THIS SEEMS TO BE A COMMON FAILURE FOR THIS CAR. NOT ONLY IS IT AN EXPENSIVE REPAIR, BUT FROM WHAT I UNDERSTAND THIS 'PULSATION DAMPER' FAILURE HAS LEAD TO MANY FIRES IN THIS CAR. I BELIEVE THE PROBLEM IS HAPPENING AGAIN AND I HOPE I DON'T HAVE TO PAY ANOTHER $500 TO HAVE IT REPAIRED AGAIN. I THINK THAT BECAUSE IT IS SO DANGEROUS AND SO COMMON IN THIS CAR, MAZDA SHOULD ACCEPT SOME OF THE RESPONSIBILITY. *AK

Recall history
3 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
94V094000 · Engine And Engine Cooling:Cooling System
Reported: 1994-05-11 (May 11, 1994)
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.
NHTSA campaign record ↗95V069000 · Fuel System, Gasoline:Delivery:Hoses, Lines/Piping, And Fittings
Reported: 1995-03-30 (March 30, 1995)
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.
NHTSA campaign record ↗96V149000 · Service Brakes, Hydraulic:Power Assist:Vacuum:Hoses, Lines/Piping, And Fittings
Reported: 1996-08-02 (August 2, 1996)
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.
