Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Oct 31, 2024
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

ELECTRICAL SYSTEM:SOFTWARE; SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE

Oct 31, 2024
105,276 units potentially affected
The defect: 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.
The 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.
The remedy: International will work with Bendix to reprogram the ECU software, free of charge. Owner notification letters were mailed December 16, 2024. Owners may contact International customer service at 1-800-448-7825. International's number for this recall is 24515.

SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT

May 25, 2023
59,684 units potentially affected
The defect: 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."
The 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.
The remedy: Towing variant vehicles under this campaign will not be repaired under recall 24V-8918. Dealers will update the software, free of charge. Owner notification letters are expected to be mailed July 24, 2023. Owners may contact Navistar's customer service at 1-800-448-7825. Navistar's number for this recall is 23515.

New CARB Idle Reduction Change Request

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
