1990 Mercury Sable problems

Defect

VEHICLE DESCRIPTION: PASSENGER VEHICLES ORIGINALLY SOLD OR CURRENTLY REGISTERED IN CONNECTICUT, DELAWARE, DISTRICT OF COLUMBIA, ILLINOIS, INDIANA, IOWA, KANSAS, KENTUCKY, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEBRASKA, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, VIRGINIA, WEST VIRGNIA, AND WISCONSIN. THE REAR LOWER SUBFRAME MOUNT PLATE NUT CAN EXPERIENCE STRESS CORROSION CRACKING IF SUBJECTED TO LONG TERM EXPOSURE TO ROAD SALTS. THIS CAN RESULT IN FRACTURE AND LOSS OF THE STRUCTURAL INTEGRITY OF THE SUBFRAME MOUNT ATTACHMENT. DETACHMENT OF THE BODY MOUNTS AT THE REAR CORNERS OF THE SUBFRAME, WHICH SUPPORTS THE ENGINE AND TRANSMISSION, ALLOWS THE REAR CORNERS OF THE SUBFRAME TO DROP.

Consequence

IF BOTH REAR CORNERS DROP, STEERING WOULD BECOME SUDDENLY VERY DIFFICULT, AFFECTING VEHICLE CONTROL AND INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL INSTALL SUBFRAME REAR MOUNT BOLTS, REINFORCEMENT PLATES, AND PLATE NUTS.

Defect

THE ARC WELDS ON THE SWAY BAR BRACKET, WHERE IT ATTACHES TO THE STRUT RESERVE TUBE, DID NOT FUSE PROPERLY.

Consequence

OVER TIME, A PORTION OF THE BRACKET CAN TEAR AWAY FROM THE STRUT, FALLING INTO AND PUNCTURING THE TIRE OR CAUSING DAMAGE TO THE WHEEL, WHICH COULD RESULT IN AN ACCIDENT.

Remedy

MONROE DEALERS WILL REPLACE THE STRUT FREE OF CHARGE.

Defect

THE RIGID MOUNTED SAFETY BELT BUCKLES ARE DEFECTIVE IN THREE WAYS. FIRST, A FASTENED SAFETY BELT BUCKLE WILL NOT UNLATCH WHEN THE RELEASE BUTTON IS DEPRESSED. THIS RESULTS FROM INTERFERENCE BETWEEN THE BUCKLE EJECTOR FINGER AND THE BUCKLE TONGUE WINDOW. THE SECOND DEFECT IS THE SAFETY BELT BUCKLE MAY NOT LATCH. THE THIRD POSSIBLE DEFECT IS THAT THE TONGUE MAY BE RETAINED BY THE BUCKLE, BUT IT MAY NOT BE LATCHED SUFFICIENTLY TO PROVIDE OCCUPANT PROTECTION.

Consequence

AN INSUFFICIENTLY LATCHED OR UNLATCHED SAFETY BELTINCREASES THE RISK OF INJURY TO SEAT OCCUPANTS IN THE EVENT OF A SUDDEN STOP ORACCIDENT. IF THE SAFETY BELT BUCKLE WILL NOT UNLATCH, IT WILL NOT ALLOW THEOCCUPANT TO GET OUT OF THE VEHICLE IN AN EMERGENCY SITUATION.

Remedy

FORD WILL REPLACE THE RIGID MOUNTED SAFETY BELT BUCKLES WITH END RELEASE SAFETY BELT BUCKLES DESIGNED TO PREVENT LATCH PROBLEMS.

Defect

CHILDREN CAN ACCIDENTALLY LOCK THEMSELVES IN THE FOOTWELL AREA OF THE REAR-FACING THIRD SEAT, OR IN THE STORAGE COMPARTMENT IN STATION WAGONS NOT EQUIPPED WITH AN OPTIONAL THIRD SEAT. ONCE THE COMPARTMENT IS CLOSED IT CANNOT BE OPENED FROM THE INSIDE.

Consequence

THERE IS A DANGER OF AIR DEPRIVATION, HYPERTHERMIA,AND/OR PANIC RESPONSE TO A CHILD WHO HAS LOCKED HIMSELF OR HERSELF INTO THECOMPARTMENT, WITH THE POSSIBILITY OF ASPHYXIATION.

Remedy

REPLACE THE SELF-LATCHING ASSEMBLY CURRENTLY USED IN THE REAR STORAGE COMPARTMENT WITH A LATCH ASSEMBLY THAT CAN ONLY BE CLOSED WITH A KEY.

Defect

FRONT DISC BRAKE ROTORS OF THE SUBJECT VEHICLES MAY EXPERIENCE SEVERE CORROSION IF OPERATED IN AREAS WHERE CALCIUM CHLORIDE AND SODIUM CHLORIDE ARE USED EXTENSIVELY.

Consequence

SEVERELY CORRODED ROTORS MAY FRACTURE OR SEPARATE NEARTHE INNER EDGES OF THE BRAKE DISCS RESULTING IN REDUCED BRAKING EFFECTIVENESS,HIGHER THAN NORMAL PEDAL EFFORTS, LOUD GRINDING NOISES, AND MODERATE PULLS WHENTHE BRAKES ARE APPLIED. REDUCED BRAKING EFFECTIVENESS MAY INCREASE MINIMUMSTOPPING DISTANCES, POSSIBLY RESULTING IN AN ACCIDENT.

Remedy

REPLACE FRONT BRAKE ROTORS WITH FULL CAST FRONT BRAKE ROTORS.

Defect

THREADED INFLATOR COMPONENTS MAY HAVE BEEN DAMAGED DURING ASSEMBLY WHICH MAY ALLOW COMPONENTS TO SEPARATE WHEN INFLATOR RECEIVES A SIGNAL TO DEPLOY THE AIR BAG.

Consequence

INFLATOR COMPONENT SEPARATION ALLOWS HOT COMBUSTION GASES TO ESCAPE INTO THE PASSENGER COMPARTMENT WHICH COULD RESULT IN INJURIES TO VEHICLE OCCUPANTS.

Remedy

REPLACE AIR BAG MODULES CONTAINING POTENTIALLY DEFECTIVE INFLATORS.

Defect

AN INCORRECT TRANSISTOR MAY CAUSE AUTOLAMP SYSTEM LIGHT SENSOR MODULE MALFUNCTION.

Consequence

HEADLAMPS COULD TURN OFF WHILE VEHICLE IS BEING DRIVEN ORREMAIN ON AFTER VEHICLE IS PARKED. LOSS OF HEADLIGHTS WHILE DRIVING AT NIGHTCOULD BE HAZARDOUS TO THE DRIVER AND OTHER TRAFIFIC.

Remedy

REPLACE LIGHT SENSOR MODULES.
