Four recalls announced in December by Navistar and Mack Trucks affect more than 14,500 International and Mack trucks, according to National Highway Traffic Safety Administration documents.

The largest of the recalls was announced by Navistar and includes approximately 12,539 International medium- and severe-duty trucks. Affected models include:

  • 2018-2019 International DuraStar
  • 2019-2020 International HV
  • 2019-2020 International MV
  • 2018-2020 International WorkStar

The affected trucks are equipped with feature cords 12VXT and 12VXU. With the parking brake applied and the automatic transmission in the “Drive” or “Reverse” position, when the stationary PTO switch is engaged by the driver, the affected trucks’ engine RPM could ramp up and may overcome the parking brake’s ability to hold the vehicle, Navistar says.

Navistar will notify owners, and dealers will update the Engine Control Module to enable the PTO neutral interlock for free. Owners can contact Navistar customer service at 1-800-448-7825 with recall number 19518. NHTSA’s recall number is 19V-841.

Navistar is also recalling approximately three model year 2020 International HV 6×4 trucks. The company says these trucks were built with a non-Quick Release Modulator Valve instead of a Quick Release Modulator Valve, which could affect the brake release time.

Navistar will notify affected owners, and dealers will replace the NQRMV with a QRMV for free. Owners can contact Navistar customer service at 1-800-448-7825 with recall number 19519. NHTSA’s recall number is 19V-838.

A recall announced by Mack Trucks affects approximately 1,879 model year 2019-2020 Mack TerraPro vocational-duty trucks. The headlights in these trucks may not be properly aimed, possibly reducing the driver’s visibility.

Mack will notify owners, and dealers will inspect and adjust the lights for free. Owners can contact Mack customer service at 1-800-866-1177 with recall number SC0421. NHTSA’s recall number is 19V-895.

Another recall issued by Mack affects approximately 80 model year 2020 Anthem, Granite and Pinnacle trucks. In these trucks, the castle nuts and cotter pins used to connect the steering drag link to the pitman arm and steering arm may not have been installed correctly, potentially causing separation of the drag link. This could cause a loss of steering control.

Mack will notify owners, and dealers will inspect and adjust the lights for free. Owners can contact Mack customer service at 1-800-866-1177 with recall number SC0420. NHTSA’s recall number is 19V-896.
