Navistar, Inc. is issuing a recall for thousands of International trucks due to an issue that could result in sudden engine shutdown.

The recall affects certain 2018-2021 International HV, 2018-2020 International HX, 2018-2019 International LT and International RH vehicles.

According to National Highway Traffic Safety Administration (NHTSA) documents, the connecting rod wrist pin in affected trucks may crack, resulting in connecting rod failure. This, in turn, could lead to an engine shutdown, increasing the risk of crash.

Navistar dealers will install new knock detection software to warn the driver prior to engine connecting rod failure, and replace connecting rods as necessary, free of charge.

The total number of trucks affected by the recall is 6,883.

Navistar is expected to mail owner notification letters on November 14, 2022.

Truck owners with questions can contact Navistar’s customer service at 1-800-448-7825 and reference recall number 22518.
