00E069000Latches & LocksNovember 6, 2000 · 16 units

Defect

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.

96V149000BrakesAugust 2, 1996 · 13,900 units

Defect

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.

95V069000Fuel SystemMarch 30, 1995 · 13,400 units

Defect

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.

94V094000EngineMay 11, 1994 · 12,316 units

Defect

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.
