2023 INTERNATIONAL HV

SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE

International Motors, LLC (International) is recalling certain 2021-2024 Lonestar, 2021-2025 RH, HV, MV, LT, HX, and 2022 PROSTAR vehicles, equipped with Bendix EC80 Advanced Electronic Control Units (ECU). Electrical noise and low signal to the power line carrier may cause the ECU to incorrectly process commands or stop working.

Risk: Safety systems that depend on the ECU (Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and Collison Mitigation System) may have diminished or lost functionality, increasing the risk of a crash.

POWER TRAIN:DRIVELINE:DRIVESHAFT

Navistar, Inc. (Navistar) is recalling certain 2023 International MV and International HV vehicles. The driveshafts can break under certain loading conditions.

Risk: A broken driveshaft can separate and cause a loss of drive power, increasing the risk of a crash.

PARKING BRAKE

Navistar, Inc. (Navistar) is recalling certain 2023 International HV, HX, LT, RH, and Lonestar vehicles. The Intellipark Tractor Park Valve Module (PVM) may intermittently become stuck in the un-parked position and fail to move into the park position when the park switch is activated.

Risk: A PVM that fails to move into park can cause a vehicle rollaway, increasing the risk of a crash.

POWER TRAIN:DRIVELINE:DRIVESHAFT

Navistar, Inc. (Navistar) is recalling certain 2023 International HV and 2023-2024 International MV vehicles. The rear axle spring wedge shim may have been incorrectly installed, which can cause U-joint failure and result in driveshaft separation.

Risk: Driveshaft separation can cause a loss of drive power and increase the risk of a crash.

ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM):SOFTWARE

Navistar, Inc. (Navistar) is recalling certain 2022-2024 International HV, International MV trucks, and 2022-2023 IC Bus TC commercial buses. When the parking brake is applied, the automatic transmission is still in drive or reverse position, and the stationary power take-off (PTO) switch is engaged by the operator, the engine may rev and overcome the parking brake's ability to keep the vehicle from moving.

Risk: Unexpected vehicle movement can increase the risk of a crash or injury.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY

Navistar, Inc. (Navistar) is recalling certain 2023 International HV and 2023-2024 International MV vehicles. The assembly bolts used to attach the battery box to the mounting bracket may be loose or missing.

Risk: Loose or missing bolts can allow the battery box to detach from the vehicle and become a road hazard, increasing the risk of a crash.

SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT

Navistar, Inc. (Navistar) is recalling certain 2021-2024 International HV, HX, LoneStar, LT, MV, eMV, and RH trucks, and IC Bus CE, 2021-2023 IC Bus RE, and 2022-2023 IC Bus TC Commercial Buses. The anti-lock brake system (ABS) indicator light does not remain illuminated when a malfunction exists, and when the vehicle's ignition switch is on, and the vehicle is in motion. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Risk: An ABS indicator light that fails to remain illuminated will not alert the driver of an ABS malfunction, which could increase the risk of a crash.

STEERING

Navistar, Inc. (Navistar) is recalling certain 2022-2023 International HX, HV, LoneStar, LT, MV, RH, IC TC Commercial Bus, and 2022 International WorkStar vehicles. The steering gears may have been assembled incorrectly, which can cause the gear to fracture.

Risk: A fractured steering gear can cause a loss of steering control, increasing the risk of a crash.

EQUIPMENT:OTHER:LABELS

Navistar, Inc. (Navistar) is recalling certain 2022-2023 International MV, International HV, and 2022 IC RE commercial buses built without a forward radar unit. The warning label notifying the driver that the collision mitigation system is inoperative may be missing.

Risk: Failure to warn the driver that the collision mitigation system is inoperative increases the risk of a crash.
