Navistar Inc. is recalling more than 92,000 trucks and buses across its lineup. An antilock braking indicator does not illuminate during emergency stopping events.

The issue affects 100% of 2021-2024 vehicles included in the noncompliance recall. No crashes or injuries associated with the condition are known, according to a post on the National Highway Traffic Safety Administration website.

Affected vehicles include the International LT series (45,931); MV (16,227); RH (4,923); HX (2,498); HV (1,259); Lone Star (704) battery-powered eMV (117); and 1,158 commercial buses. Navistar recalled 19,376 school buses for the same issue in a separate recall. The total vehicles in the recall is 92,193.

The ABS indicator lamp is out of compliance with the Federal Motor Vehicle Safety Standard that requires the ABS indicator lamp remain activated when a malfunction exists. That includes whenever the vehicle’s ignition switch is in the on (run) position, and the vehicle is in motion.


Lack of ABS indicator can lead to a crash

If the lamp does not stay illuminated during a braking event that requires ABS, a vehicle operator may not realize there is a fault with the ABS system. That can increase the risk of a vehicle crash.

The brake system Electronic Control Unit blink code function interferes with the ABS indicator lamp signal broadcast over the Controller Area Network, causing the ABS indicator lamp to turn off. The ABS indicator lamp re-illuminates when the vehicle comes to a stop. Traction control and stability control indicator lamps stay on, which could warn the driver of a problem.

The remedy is a software update that disables the blink code function so it does not interfere with fault logic commands for the ABS lamp. 

Customer and dealer notification letters will be mailed July 24. The NHTSA recall number for the trucks and commercial buses is 23V-370. The school bus recall number 23V-371.

    I drive a 2021, I have been having issues with the trailer ABS warning light coming on both on the trailer and dash. When I do a code check (turn on the key, turn it off, then back on) I get code 666 from the indicator light on the trailer.
    When I switch trailers the indicator lights are off for a period of time, then return.
    A few shops have looked at it to no avail.
    Recently I completely disconnected from the trailer I am pulling and drove a moment above 5 mph, then reattached. Lights are out. I will see how long this lasts.
    To the point, I am wondering if this may be related to the recall issue?
