2021 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.

PARKING BRAKE

Navistar, Inc. (Navistar) is recalling certain 2018-2021 International HV, 2019-2021 International RH, 2019-2022 International MV, and 2022 International HX vehicles. A software error in the Body Control Module (BCM) may allow the vehicle to overcome the park brake during power-take-off (PTO) operation.

Risk: A parking brake that does not hold can allow the vehicle to move unexpectedly and increase the risk of a crash or injury.

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.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Navistar, Inc. (Navistar) is recalling certain 2018-2019 International WorkStar, International DuraStar, 2019-2021 International HV, International MV, and IC Bus RE Commercial Bus vehicles. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

SERVICE BRAKES, AIR

Navistar, Inc. (Navistar) is recalling certain 2021 International LT, RH, MV, and HV vehicles equipped with Bendix pressure switches. A retainer was not properly seated in the SC-3 single check valve and may not provide source air isolation when pressure is applied. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Risk: Unintended spring brake application may occur, increasing the risk of a crash.

EXTERIOR LIGHTING

Navistar, Inc. (Navistar) is recalling certain 2021 International MV and HV vehicles equipped with feature code 10EWW, 10EYD, 10HYR, or 10JPJ (Fifth wheel, stationary), 10HJA (Fifth wheel, air slide) or 10WDN (Fifth wheel mounting angles). The vehicles may not have had sections of reflective tape applied to the right and left upper contours of the cab. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamp, Reflective Devices, and Associated Equipment."

Risk: Without the reflective strips, a truck operating without a trailer at night may be less visible, increasing the risk of a crash.

FUEL SYSTEM, DIESEL: PRE-HEATER

Navistar, Inc. (Navistar) is recalling certain 2017-2020 International WorkStar and International DuraStar, 2018-2019 IC 1300 FBC Commercial and IC HC Commercial, 2018-2021 IC CE Commercial, International MV and International HV, and 2019-2021 IC TC Commercial buses with Cummins B6.7 diesel engines with a fuel module option number FS90301 or FS90453. The electric fuel heater within the fuel module may overheat and cause plastic in the fuel heater to melt and potentially catch fire. It may also lead to engine stalling.

Risk: A fire increases the risk of injury. An engine stall can increase the risk of a crash.
