METAL STRAP SECURING FUEL TANK TO VEHICLE RUSTED AND BROKE; DEFECT DISCOVERED BEFORE ANY CRASH/PERSONAL INJURY; CONTACTED MANUFACTURER'S DEALER FOR REPLACEMENT PART AND WAS ADVISED NONE AVAILABLE NOW NOR LIKELY TO BE AVAILABLE IN FUTURE; HAD TO ARRANGE FOR CUSTOM MANUFACTURE OF REPLACEMENT PART. I STILL HAVE PART OF THE RUSTED STRAP. THIS PART SHOULD HAVE BEEN MADE OF A MORE DURABLE MATERIAL CONSIDERING THE FUNCTION IT SERVES; RUSTING ISSUE COMPOUNDED BY THE FACT THAT A LOOSE-FITTING COVER GOES OVER THE STRAP AND SAME APPEARS TO TRAP WATER, …

7 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
91V027000 · Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings
Reported: 1991-02-13 (February 13, 1991)
REAR BRAKE TUBE ROUTING IS CONTACTED BY FUEL TANK HEAT SHIELD WHEN SUSPENSION IS IN FULL JOUNCE POSITION. THIS DAMAGES THE BRAKE FLUID TUBE, CAUSING A LEAK.
Consequence: LOSS OF FLUID FROM HALF OF THE DIAGONALLY SPLIT BRAKEHYDRAULIC SYSTEM AFFECTS BRAKING CAPABILITY, WHICH COULD RESULT IN AN ACCIDENT.
Remedy: MODIFY HEAT SHIELD TO ELIMINATE POTENTIAL FOR SHIELD CONTACTING BRAKE TUBE.
ROUTING OF BATTERY MAIN FEED WIRING MAY ALLOW IT TO CONTACT THE AIR CLEANER BRACKET AND CONTNUED CONTACT MAY LEAD TO AN ELECTRICAL SHORT CIRCUIT.
Consequence: THE ELECTRICAL SHORT CAUSED BY CONTINUOUS CONTACT COULDRESULT IN THE IGNITION OF THE WIRING INSULATION, AND AN UNDERHOOD FIRE.
Remedy: THE MAIN FEED ON ALL INVOLVED VEHICLES WILL BE REROUTED AND SECURED WITH TIE STRAPS AWAY FROM THE AIR CLEANER BRACKET.
NHTSA campaign record ↗91V191000 · Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings
Reported: 1991-11-01 (November 1, 1991)
THE ANTI-LOCK BRAKE SYSTEM HIGH PRESSURE HOSE MAY LEAK OR DETACH AT ITS CRIMPED END FITTING RESULTING IN THE DISCHARGE OF HYDRAULIC FLUID.
Consequence: FLUID DISCHARGE EVENTUALLY CAUSES THE LOSS OF BOTH THEANTI-LOCK BRAKE SYSTEM AND HYDRAULIC ASSIST FOR THE BRAKE SYSTEM, RESULTING ININCREASED LIKELIHOOD OF BRAKE LOCKUP AND INCREASED STOPPING DISTANCES, WHICHCOULD RESULT IN A VEHICLE ACCIDENT.
Remedy: REPLACE THE ABS HIGH PRESSURE HOSE WITH A HOSE OF DIFFERENT DESIGN AND CONSTRUCTION.
THE END CAP CONNECTING THE HEAT EXCHANGER'S CORE TO THE ENGINE COOLING SYSTEM COULD RUPTURE AND ALLOW HOT COOLANT TO ESCAPE INTO THE PASSENGER COMPARTMENT.
Consequence: THE COOLANT ESCAPING INTO THE PASSENGER COMPARTMENT COULD CONTACT THE DRIVER'S FEET AND INJURE THE DRIVER. ALSO, STEAM FROM THE HEATER LIQUID WILL CLOUD ON THE WINDOW SURFACES AND IMPAIR THE DRIVER'S VISION. IN EITHER CASE, FAILURE OF THE HEATER CORE END CAP COULD RESULT IN A VEHICLE ACCIDENT.
Remedy: A COOLANT TEMPERATURE CONTROLLED HEATER CORE FLUID BYPASS VALVE WILL BE INSTALLED.
THE AUTOMATIC SHOULDER BELT SYSTEMS CAN MALFUNCTION AND BECOME INOPERATIVE.
Consequence: THE LACK OF PASSIVE RESTRAINTS COULD INCREASE THE RISK OF PERSONAL INJURY IN THE EVENT OF A VEHICLE COLLISION.
Remedy: DEALERS WILL REPLACE THE SYSTEM TRACK AND DRIVE ASSEMBLY ON AUTOMATIC SHOULDER BELT SYSTEMS WHICH ARE CURRENTLY INOPERATIVE AND THOSE SYSTEMS WHEN THEY BECOME INOPERATIVE IN THE FUTURE.
NHTSA campaign record ↗96V099000 · Service Brakes, Hydraulic:Antilock/Traction Control/Electronic Limited Slip
Reported: 1996-06-13 (June 13, 1996)
THE ABS HYDRAULIC CONTROL UNIT CAN EXPERIENCE EXCESSIVE BRAKE ACTUATOR PISTON SEAL WEAR CAUSING PUMP-MOTOR DETERIORATION.
Consequence: IF THIS CONDITION OCCURS, THE ABS FUNCTION COULD BE LOST AND REDUCED POWER ASSIST WOULD BE EXPERIENCED DURING VEHICLE BRAKING INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.
Remedy: DEALERS WILL TEST THE VEHICLE'S ANTI-LOCK BRAKE SYSTEM AND REPAIR THE VEHICLES IF NECESSARY. ALSO THE WARRANTY ON ALL ABS COMPONENTS WILL BE EXTENDED TO 10 YEARS OR 100,000 MILES (EXCEPT FOR THE BRAKE ACTUATOR PISTON ASSEMBLY AND THE PUMP-MOTOR ASSEMBLY WHICH WILL HAVE A LIFETIME COVERAGE). OWNERS WILL ALSO BE REIMBURSED FOR PREVIOUS ABS COMPONENT REPAIR COSTS.
NHTSA campaign record ↗98V005000 · Service Brakes, Hydraulic:Foundation Components:Disc:Rotor
Reported: 1998-01-12 (January 12, 1998)
VEHICLE DESCRIPTION: PASSENGER AND MULTI-PURPOSE VEHICLES ORIGINALLY SOLD OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, ILLINOIS, INDIANA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, OR WISCONSIN, AND THE DISTRICT OF COLUMBIA. THE FRONT DISC BRAKE ROTORS CAN EXPERIENCE SEVERE CORROSION IF OPERATED FOR AN EXTENSIVE PERIOD IN THE "SALT BELT." IF THE ROTORS ARE NOT REPLACED, THE CORROSION CAN EVENTUALLY COMPROMISE THE STRUCTURAL INTEGRITY OF THE STAMPED STEEL CENTER HUB SECTION OF THE ROTOR.
Consequence: THE REDUCED STRENGTH CAN ALLOW THE CAST IRON WEAR SURFACE TO SEPARATE FROM THE HUB, REDUCING THE BRAKE EFFECTIVENESS OF THE VEHICLE.
Remedy: DEALERS WILL REPLACE THESE ROTORS WITH ROTORS THAT ARE COATED WITH A CORROSION PROTECTION.
