Most recent first. Recall repairs are free at any authorised dealer. Click a recall for the full defect, consequence and remedy text.

  1. Idler and attachment (steering)

    NHTSA 86V026000 Reported 120,292 vehicles potentially affected NAVISTAR INTL CORP.

    Steering arm may crack after repeated full lock turns due to the lack of end-of-travel relief features. Consequence of defect: loss of steering control would be experienced if cracks expand to complete fracture of the arm, and a crash could occur without prior warning.

    Remedy: Replace steering arm with a redesigned strengthened arm.

  2. Arm (steering)

    NHTSA 85V037000 Reported 31,746 vehicles potentially affected NAVISTAR INTL CORP.

    The steering arm may crack after repeated full-lock turns. Consequence of defect: if cracks progress to complete fracture of the arm, steering control would be lost and a vehicle accident could occur.

    Remedy: Replace steering arm with redesigned strengthened arm.

  3. Gear box (other than rack and pinion) (steering)

    NHTSA 83V001000 Reported 3,500 vehicles potentially affected INTERNATIONAL HARVESTER

    Under certain circumstances, the output shaft of the steering gear may develop cracks at a location between the gear and the pitman arm mounting. The suspect component is found on steering gears with the code 05057. Continued operation may result in fracture and disconnection of the steering linkage.

    Remedy: The dealer will remove original output shaft from steering gear and replace it with a new case-hardened shaft free of charge.

  4. Hoses, lines/piping, and fittings (service brakes)

    NHTSA 80V030000 Reported 4,180 vehicles potentially affected INTERNATIONAL HARVESTER

    The brake fluid lines which run to and from the frame mounted power assist unit may be incorrectly routed resulting in the lines rubbing or chafing on a fender splash shield bracket.

    Remedy: All vehicles will be inspected and, if necessary, the brake lines will be repositioned to provide clearance to the splash shield bracket at no charge to owners.

Checking a specific 1979 International Harvester S1900

How do I know if my 1979 International Harvester S1900 has an open recall?

Enter your 17-character VIN above. The VIN is on the driver's side dashboard (visible through the windshield), the driver's door jamb sticker, and your registration or insurance card. The check runs against NHTSA's live database and tells you which campaigns list your vehicle. 4 campaigns currently list the 1979 International Harvester S1900; your car may already have been repaired under some of them.

Is the recall repair free?

Yes. Under federal law, manufacturers must fix safety recalls at no charge for vehicles up to 15 years old from the date of sale to the first owner. Contact any authorised International Harvester dealer with your VIN and the NHTSA campaign number (for example 80V030000).

What is the difference between a recall and a complaint?

A recall is a safety campaign filed by the manufacturer or ordered by NHTSA, with a defined defect and remedy. A complaint is a report an owner sent to NHTSA; it is not verified, but patterns of complaints are what trigger NHTSA investigations and, eventually, recalls.
