9 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
77V098000 · Suspension:Front:Control Arm:Lower Arm
Reported: 1977-06-22 (June 22, 1977) · Model years: 1975
THE FRONT SUSPENSION CONTROL ARMS WERE ASSEMBLED WITH BALL JOINTS WHICH MAY CONTAIN SOCKETS THAT WERE NOT PROPERLY HEAT-TREATED. THIS MAY CAUSE THE SOCKET TO WEAR RAPIDLY AND ALLOW THE BALL JOINT STUD TO SEPARATE FROM THE SOCKET, CAUSING EITHER THE LEFT OR RIGHT WHEEL SUSPENSION TO COLLAPSE.
Remedy: DEALER WILL INSPECT AND, WHERE NECESSARY, WILL REPLACE THE BALL JOINTS WITHOUT CHARGE TO OWNER.
NHTSA campaign record ↗77V111000 · Service Brakes, Hydraulic:Foundation Components:Master Cylinder
Reported: 1977-07-15 (July 15, 1977) · Model years: 1976, 1977
ON THE INVOLVED VEHICLES, THE BRAKE MASTER CYLINDER MAY HAVE BEEN ASSEMBLED WITH RESERVOIR MOUNTING BOLTS THAT WERE IMPROPERLY PROCESSED. THIS COULD MAKE THESE BOLTS BRITTLE AND SUBJECT TO BREAKING. IF BREAKAGE OCCURS, A BRAKE FLUID LEAK MAY DEVELOP BETWEEN THE RESERVOIR AND MASTER CYLINDER. LOSS OF BRAKE FLUID WOULD ADVERSELY AFFECT VEHICLE BRAKING CAPABILITY.
Remedy: DEALER WILL REPLACE THE MASTER CYLINDER RESERVOIR MOUNTING BOLTS WITH AN IMPROVED TYPE, WITHOUT CHARGE TO OWNER.
NHTSA campaign record ↗76V198000 · Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings
Reported: 1976-12-10 (December 10, 1976) · Model years: 1977
NHTSA campaign record ↗78V107000 · Fuel System, Gasoline:Delivery:Hoses, Lines/Piping, And Fittings
Reported: 1978-05-15 (May 15, 1978) · Model years: 1978
ON THE INVOLVED VEHICLES, AN INTERFERENCE CONDITION MAY EXIST BETWEEN THE CARBURETOR FUEL PIPE ASSEMBLY AND THE AIR CONDITIONING BRACKET. THIS COULD EVENTUALLY CAUSE THE PIPE TO WEAR THROUGH DUE TO VIBRATION AND FUEL PRESSURE PULSATION.
Remedy: DEALER WILL INSPECT AND, IF NECESSARY, REPOSITION THE CARBURETOR FUEL PIPE AT NO CHARGE.
Reported: 1979-06-06 (June 6, 1979) · Model years: 1979
ON THE INVOLVED VEHICLES THE BRAKE STOPLIGHT AND CRUISE CONTROL SWITCH WHICH IS OPERATED BY THE BRAKE PEDAL MAY HAVE BEEN ASSEMBLED WITH AN INCORRECT LUBRICANT ON THE ACTUATING PLUNGER. THIS CAN CAUSE THE REAR BRAKE STOPLIGHTS TO BECOME INOPERATIVE AND THE CRUISE CONTROL, IF ACTIVATED, TO STAY ELECTRICALLY ENGAGED.
Remedy: DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE BRAKE STOPLIGHT AND CRUISE CONTROL SWITCH AT NO COST TO OWNER.
Reported: 1991-10-21 (October 21, 1991) · Model years: 1992
A MISADJUSTED TRANSMISSION CABLE CAN ALLOW THE ENGINE TO BE STARTED WHILE THE TRANSMISSION IS IN A FORWARD OR REVERSE DRIVE GEAR.
Consequence: THE VEHICLE CAN BE STARTED AND THEN MOVE IN AN UNEXPECTEDDIRECTION, RESULTING IN A VEHICLE CRASH WITHOUT PRIOR WARNING. THE VEHICLE ALSOFAILS TO COMPLY WITH THE REQUIREMENTS OF FMVSS 102.
Remedy: RESET THE TRANSMISSION CABLE ROUTING TO A REVISED PATHWAY.
NHTSA campaign record ↗96V092000 · Suspension:Rear:Springs:Leaf Spring Assembly:U-Bolt, Leaf Spring To Axle
Reported: 1996-06-03 (June 3, 1996) · Model years: 1996
ONE OF THE FOUR REAR AXLE U-BOLTS CAN BREAK. THIS CAN POTENTIALLY LEAD TO THE SPRING LIFTING FROM THE AXLE UNDER CERTAIN REBOUND, BRAKING OR CORNERING MANEUVERS.
Consequence: THIS CONDITION COULD RESULT IN SUDDEN LOSS OF VEHICLE CONTROL INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.
Remedy: DEALERS WILL REPLACE THE FOUR REAR AXLE U-BOLTS ON THE AFFECTED VEHICLES.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
