6 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
79V054000 · Service Brakes, Air:Supply:Hoses, Lines/Piping, And Fittings
Reported: 1979-02-22 (February 22, 1979) · Model years: 1979
THE AIR BRAKE LINES MAY BE ROUTED TOO CLOSE TO THE EXHAUST MUFFLER. BECAUSE THE AIR BRAKE LINES ARE MADE OF NYLON MATERIAL, HEAT FROM THE EXHAUST MUFFLER CAN WEAKEN THE BRAKE LINE TUBES, POSSIBLY CAUSING THEM TO RUPTURE. TUBE RUPTURE COULD RESULT IN LOSS OF AIR IN THE SECONDARY AIR BRAKE SYSTEM.
Remedy: NEW NYLON AIR BRAKE TUBES WILL BE INSTALLED AND REROUTED WITHOUT CHARGE TO OWNER.
NHTSA campaign record ↗81V090000 · Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings
Reported: 1981-07-17 (July 17, 1981) · Model years: 1981
THE INVOLVED VEHICLES WERE ASSEMBLED WITH THE LEFT FRONT BRAKE TUBE RETAINING CLIP MISSING. THE ABSENCE OF A RETAINING CLIP MAY ALLOW THE BRAKE TUBE TO RUB AGAINST THE SHOCK ABSORBER, CAUSING WEAR ON THE TUBE AND, EVENTUALLY, LOSS OF BRAKE FLUID.
Remedy: MISSING BRAKE TUBE CLIPS WILL BE INSTALLED AND ANY CHAFED BRAKE TUBES WILL BE REPLACED.
THESE VEHICLES MAY HAVE BEEN MANUFACTURED WITH AN INCORRECT END CLAMP ON THE HAND THROTTLE ACTUATING CABLE. UNDER CERTAIN CONDITIONS, PERTAINING TO THE CLAMP-TO-THROTTLE CABLE ORIENTATION AND DISTANCES OF THE CABLE TO GOVERNOR SHAFT, THE THROTTLE CABLE END CLAMP MAY INTERFERE WITH THE OUTBOARD ACCELERATOR.
Remedy: THE DEALER WILL INSPECT HAND THROTTLE CLAMP FOR INTERFERENCE AND, IF NECESSARY, REPLACE THESE CLAMPS FREE OF CHARGE.
Reported: 1983-02-15 (February 15, 1983) · Model years: 1983
ON THE AFFECTED VEHICLES, THE WIRING ASSEMBLY TO THE FLOOR MOUNTED HEADLAMP DIMMER SWITCH MAY BE TOO TIGHT; SHOULD WIRES DISCONNECT, THE HEADLIGHTS WILL NOT OPERATE.
Remedy: THE DEALER WILL MODIFY THE DIMMER SWITCH WIRING WITH A WIRE EXTENSION ASSEMBLY AT NO CHARGE TO OWNER.
NHTSA campaign record ↗84V135000 · Service Brakes, Hydraulic:Power Assist:Vacuum:Hoses, Lines/Piping, And Fittings
Reported: 1984-10-23 (October 23, 1984) · Model years: 1984
THE INVOLVED VEHICLES WERE PRODUCED WITH HYDRAULIC BRAKE BOOSTER SUPPLY HOSES THAT ARE LOCATED TOO CLOSE TO THE ENGINE EXHAUST MANIFOLD AND MAY CHAFE AND DEVELOP HEAT DAMAGE DURING VEHICLE OPERATION. CHAFING AND HEAT INDUCED DETERIORATION OF A HOSE DUE TO DIRECT CONTACT WITH THE MANIFOLD MAY CAUSE THE HOSE TO WEAR. A SUBSEQUENT RUPTURE WILL RESULT IN PUMP FLUID LOSS.
Remedy: THE DEALER WILL RELOCATE AND REPLACE THE BRAKE BOOSTER SUPPLY TUBE AND HOSE AS NECESSARY AT NO COST TO OWNER.
NHTSA campaign record ↗97V091000 · Power Train:Automatic Transmission:Gear Position Indication (Prndl)
Reported: 1997-05-28 (May 28, 1997) · Model years: 1998
VEHICLE DESCRIPTION: MEDIUM DUTY TRUCKS AND SCHOOL BUS CHASSIS-COWLS EQUIPPED WITH AUTOMATIC TRANSMISSIONS. THE WELDS THAT ATTACH THE KEY TO THE TOP OF THE STEERING COLUMN MOUNTED AUTOMATIC TRANSMISSION SHIFT LINKAGE MAY NOT ADEQUATELY RETAIN THE KEY, ALLOWING THE TRANSMISSION TO BE IN A GEAR OTHER THAN THAT INDICATED ON THE "PRNDL", OR IN SOME CASES, "RNDL."
Consequence: THE DOMESTIC SPECIAL ORDER (DSO) PARK BRAKE MAY NOT ENGAGE WHEN THE SHIFT LEVER IS PLACED IN THE PARK POSITION, OR IN THE VEHICLE MOVING IN AN UNINTENDED DIRECTION WHEN THE ACCELERATOR IS PRESSED. IN SOME VEHICLES THE DSO PARKING BRAKE MECHANISM ALSO MAY NOT BE PROPERLY ADJUSTED, WHICH CAN RESULT IN THE PARK BRAKE NOT ENGAGING WHEN THE SHIFT LEVER IS PLACED IN THE PARK POSITION, INCREASING THE RISK OF A VEHICLE CRASH.
Remedy: DEALERS WILL REPLACE THE STEERING COLUMN SHIFT TUBE AND, IF SO EQUIPPED, TO HAVE THE DSO PARK BRAKE LINKAGE ADJUSTED.

BLUE BIRD CHASIS; AUTOMATIC TRANSMISSION WILL DOWNSHIFT SEVERELY, HARD WHILE TRANSPORTING CHILDREN. DRIVER HAS TO TURN BUS OFF, GETS OFF, GOES UNDER HOOD TO PUSH A CABLE BACK INTO THE HOUSING. THIS IS A REOCCURRING FAILURE, AND FORD IS AWARE OF THE CONDITION. BUT THE ONLY REMEDY OFFERED AT THIS TIME IS TO SPRAY THE CABLE. *AK

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.
