Year-by-year records
Recall history
6 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
81V083000 · Structure:Body
Reported: 1981-07-07 (July 7, 1981) · Model years: 1978, 1979, 1980, 1981
THE RIGHT HAND FRONT CANOPY CAB MOUNTING BRACKET INTERFERES WITH THE RIGHT HAND BRAKE CHAMBER ON THE STEERING AXLE WHEN IN A CERTAIN DEGREE TURN AND SEVERE BUMPING IS PRESENT.
Remedy: THE FRONT CANOPY CAB MOUNTING BRACKET WILL BE MODIFIED TO ALLOW FOR CLEARANCE OF THE RIGHT HAND FRONT BRAKE CHAMBER, WITHOUT CHARGE TO OWNER.
NHTSA campaign record ↗84V036000 · Suspension:Rear:Springs:Leaf Spring Assembly
Reported: 1984-03-23 (March 23, 1984) · Model years: 1978, 1979, 1980, 1981, 1982
SPRING SEAT CAN DEFORM, WHICH CAUSES A DECREASE IN THE CLAMPING FORCE IN THE SUSPENSION ASSEMBLY. LOSS OF CLAMPING FORCE MAY BRING ABOUT AXLE MISALIGNMENT OR AXLE HOUSING FAILURE.
Remedy: THE AXLE HOUSING WILL BE INSPECTED AND REPLACED, IF NECESSARY. THE SPRING SEATS WILL ALSO BE REPLACED.
NHTSA campaign record ↗80V052000 · Parking Brake:Driveline:Air
Reported: 1980-05-06 (May 6, 1980) · Model years: 1979, 1980
ON CERTAIN VEHICLES, THE KNOB THAT OPERATES THE TRACTOR PARK VALVE MAY BREAK OFF, RENDERING THE VALVE INOPERABLE.
Remedy: DEFECTIVE KNOBS WILL BE REPLACED WITH AN IMPROVED TYPE, WITHOUT CHARGE TO OWNER.
NHTSA campaign record ↗81V088000 · Service Brakes, Air:Controls:Hand Control/Valve
Reported: 1981-07-08 (July 8, 1981) · Model years: 1979, 1980
THE RETAINING PIN FOR THE BRAKE CONTROL KNOB HAS BEEN MISALIGNED (OFF THE CENTER LINE OF THE VALVE PLUNGER HOLE). THIS CAUSES THE KNOB TO BE OVERSTRESSED AT THE RETAINING PIN HOLE AREA CAUSING IT TO SEPARATE FROM THE VALVE.
Remedy: THE HOLES WILL BE RETOOLED TO PROVIDE CORRECT ALIGNMENT AND PLASTIC KNOBS WILL BE REPLACED BY KNOBS OF STRONGER MATERIAL HAVING METAL REINFORCEMENTS.
NHTSA campaign record ↗81V155000 · Steering:Gear Box:Shaft Pitman
Reported: 1981-12-29 (December 29, 1981) · Model years: 1981
THE PITMAN ARM RETAINING BOLT MAY NOT HAVE BEEN TIGHTENED TO THE REQUIRED SPECIFICATIONS DUE TO A DESIGN CHANGE. INADEQUATE RETENTION OF THE BOLT TO THE OUTPUT SHAFT COULD ALLOW THE PITMAN ARM TO LOOSEN.
Remedy: THE DEALER WILL INSPECT AND, IF NECESSARY, RETORQUE THE RETAINING BOLT TO PROPER SPECIFICATIONS AT NO CHARGE.

Darker cells indicate a larger share of submitted complaints. Components overlap. This measures complaint composition, not failure probability.
Failure mileage by component
Median and middle 50% of usable owner-reported mileages. Ranges require at least five records.

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.
1983: 0 complaints · 1984: 0 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
|---|---|---|---|
| 1983 | 0 | 0 | 0 |
| 1984 | 0 | 0 | 0 |
Date coverage across each selected cohort
| Year | Incident dates used | Filing date fallbacks | Excluded dates |
|---|---|---|---|
| 1983 | 0 | 0 | 0 |
| 1984 | 0 | 0 | 0 |
Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
