Year-by-year records
Recall history
9 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
80V025000 · Service Brakes, Hydraulic:Pedals And Linkages
Reported: 1980-03-07 (March 7, 1980) · Model years: 1979, 1980
THE ENGINE BOX ON SOME UNITS MAY HAVE BEEN INCORRECTLY MANUFACTURED, CAUSING IT TO PROTRUDE PAST THE TOE BOARD FLANGE. THIS PROTRUSION COULD HINDER THE MOVEMENT OF THE DRIVER"S RIGHT FOOT FROM THE ACCELERATOR PEDAL TO THE BRAKE.
Remedy: DEALER WILL INSPECT AND, IF NECESSARY, CORRECT THE PROBLEM WITH A REPAIR KIT WITHOUT CHARGE TO OWNER.
NHTSA campaign record ↗81V050000 · Service Brakes, Hydraulic:Pedals And Linkages
Reported: 1981-04-10 (April 10, 1981) · Model years: 1981
ON CERTAIN VEHICLES, A LOCKNUT ON A BOLT HOLDING THE BRAKE PEDAL LEVER TO THE BRAKE PEDAL BRACKET MAY NOT HAVE BEEN TIGHTENED ENOUGH TO ENGAGE THE LOCKING MECHANISM OF THE NUT. THIS NUT COULD VIBRATE LOOSE, AND THE BRAKE PEDAL WOULD NO LONGER FUNCTION.
Remedy: THE NUT WILL BE INSPECTED AND TIGHTENED, IF NECESSARY, TO ENSURE PROPER ENGAGEMENT OF LOCKING MECHANISM OF THE NUT.
NHTSA campaign record ↗85V147000 · Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings
Reported: 1985-11-13 (November 13, 1985) · Model years: 1983, 1984
THE ROUTING OF BRAKE LINES BROUGHT THE LINE CLOSE TO AN AREA USED TO FASTEN THE SEAT SOCKET SUPPORT STRUCTURE TO THE CHASSIS. THE FASTENING OF SEAT SUPPORT IS DONE WITH BOLTS AND WHEN THE BOLTS ARE TIGHTENED THE FREE END OF THE BOLTS PINCHES ONE OF THE BRAKE LINES AGAINST THE CHASSIS FRAME RAIL. THIS CAUSES A REDUCTION IN THE BRAKE LINE WHICH REDUCES THE VOLUME OF FLUID PASSING THROUGH THE LINE. CONSEQUENCE OF DEFECT: THE REDUCED VOLUME OF FLUID AFFECTS THE EFFICIENCY OF THE BRAKE SYSTEM. ALSO THE BRAKE LINE MAY CRACK CAUSING LOSS OF FLUID LINE . IN EITHER CASE, A LONGER STOPPING DISTANCE WOULD BE REQUIRED WHEN MAXIMUM BRAKE EFFICIENCY IS NEEDED. OPERATION OF A VEHICLE WITH DAMAGED BRAKES COULD LEAD TO A VEHICLE CRASH.
Remedy: INSPECT AND REPLACE THE AFFECTED BRAKE LINE WITH A NEW PART.
NHTSA campaign record ↗85V167000 · Trailer Hitches:Fifth Wheel Assembly
Reported: 1985-12-20 (December 20, 1985) · Model years: 1983
THE REINFORCING PLATES WERE OMITTED FROM THE TRAILER PIN BOX ASSEMBLY, WHICH IS USED TO HOLD THE FIFTH WHEEL ASSEMBLY TO THE TRAILER. CONSEQUENCE OF DEFECT: A FATIQUE FAILURE OFF THE PIN BOX ALLOW THE FIFTH WHEEL ASSEMBLY TO SEPARATE FROM THE TRAILER. THEREFORE, THE TRAILER WILL FALL OFF THE TOWING TRUCK AND ROLL UNCONTROLLED ON THE ROADWAY. THIS MAY CAUSE AN ACCIDENT.
Remedy: REPLACE THE PIN BOX ASSEMBLY IF REINFORCEMENT PLATES ARE MISSING.
NHTSA campaign record ↗87V036000 · Fuel System, Gasoline:Delivery:Hoses, Lines/Piping, And Fittings
Reported: 1987-03-16 (March 16, 1987) · Model years: 1983, 1984, 1985, 1986, 1987
CLAMP WHICH SECURES THE FUEL FILLER HOSE TO THE BODY IS MISSING.
Consequence: HOSE COULD SAG ONTO REAR SPRING WEARING A HOLE IN THEHOSE; THIS COULD ALLOW FUEL TO SPILL ONTO GROUND WHILE FILLING OR DRIVINGTRUCK.
Remedy: INSTALL MISSING CLAMP AND REPLACE FILLER HOSE IF IT HAS BEEN RUBBED BY SPRING.
NHTSA campaign record ↗86V064000 · Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings
Reported: 1986-05-19 (May 19, 1986) · Model years: 1986
A SUPPORT THAT CONNECTS THE BODY TO THE CHASSIS LIES AGAINST THE BRAKE LINE THAT CONNECTS THE MASTER CYLINDER TO THE BRAKE WARNING SWITCH. CONTINUED VIBRATIONS MAY CAUSE THE BRAKE LINES TO WEAR THROUGH AND RESULT IN LOSS OF HYDRAULIC FLUID. CONSEQUENCE OF DEFECT: LOSS OF HYDRAULIC FLUID RESULTS IN COMPLETE LOSS OF BRAKES, WHICH COULD LEAD TO AN ACCIDENT.
Remedy: REROUTE AND/OR REPLACE BRAKE LINES AND SUPPORT TO AVOID CONTACT.
NHTSA campaign record ↗87V061000 · Suspension:Multiple Axle
Reported: 1987-05-01 (May 1, 1987) · Model years: 1987
INCORRECT GRADE BOLTS WERE USED IN ATTACHING THE BODY TO THE CHASSIS AND IN ATTACHING THE SEAT ONTO THE CHASSIS.
Consequence: PROPER TORQUE COULD NOT BE ACHIEVED AND BODY COULDSEPARATE FROM THE CHASSIS DURING AN IMPACT.
Remedy: REPAIR TO ELIMINATE INCORRECT BOLT PROBLEM.
NHTSA campaign record ↗88V004000 · Exterior Lighting:Headlights:Switch
Reported: 1988-01-13 (January 13, 1988) · Model years: 1987
THE HEADLAMP SWITCH IS NOT IDENTIFIED AS REQUIRED BY FMVSS/101.
Consequence: VEHICLES DO NOT COMPLY WITH FMVSS 101.
Remedy: PROVIDE A DECAL TO BE PLACED ON INSTRUMENT PANEL ADJACENT TO THE HEADLAMP SWITCH.
NHTSA campaign record ↗90V046000 · Power Train:Automatic Transmission:Gear Position Indication (Prndl)
Reported: 1990-03-08 (March 8, 1990) · Model years: 1989, 1990
Consequence: INABILITY TO SEE GEAR SHIFT POSITION INDICATOR COULD PRESENT AN ACCIDENT HAZARD IF DRIVER IS NOT AWARE OF THE GEAR VEHICLE IS IN.
Remedy: SHORTEN INSTRUMENT PANEL TO MAKE GEAR POSTION INDICATOR VISIBLE TO THE DRIVER.

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.
1989: 0 complaints · 1990: 0 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |

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.
