IC BUS RECB

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.

STRUCTURE:EMERGENCY:ESCAPE/EGRESS/EXIT

Navistar, Inc. (Navistar) is recalling certain 2019-2020 IC RE and IC CE commercial buses equipped with feature code 48PZP, 48PZR, 48RZY, 48SXV, or 48SZG (Prolo emergency exit roof hatches). Due to a manufacturing issue, the roof hatch external handle may unexpectedly break under reasonable use.

Risk: If the roof hatch external handle breaks, in the event of an emergency, the hatch cannot be easily opened from outside the vehicle, increasing the risk of injury.

SERVICE BRAKES, AIR:DISC:CALIPER

Navistar, Inc. (Navistar) is recalling certain 2016-2020 IC CE and 2019 IC RE school buses equipped with Bendix ADB 22X brake calipers. The driver side rear brakes may drag.

Risk: A dragging brake may cause damage to the brake components, which may activate the ABS warning light. The warning light may cause the driver to immediately stop the vehicle and transfer occupants. Additionally, the high temperatures at the wheel end can increase the risk of a fire. Either condition increases the risk of injury.

SERVICE BRAKES, AIR

Navistar, Inc. (Navistar) is recalling certain 2019 International HX, DuraStar, WorkStar, HV, LoneStar, LT, MV, and RH vehicles, and IC Bus HC, CE, and RE vehicles equipped with long stroke brake chambers and spring actuated parking brakes. The spring actuated parking brake may be improperly crimped to the long stroke service brake chamber, causing a service brake air leak and the possible separation of the spring brake chamber from the service brake section.

Risk: An air leak or separation of the spring brake chamber can increase the needed stopping distance, increasing the risk of a crash.

SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS

Navistar, Inc. (Navistar) is recalling certain 2015-2018 IC Bus RE commercial buses. The drop hose fittings for the air brakes may not be oriented correctly, and, as a result, the brake hoses may contact the tire when the wheels are turned to the limit.

Risk: Contact with the tires may damage the service brake air hose, causing the brakes to become inoperative or lengthening the distance needed to stop the bus, increasing the risk of a crash.

EQUIPMENT ADAPTIVE/MOBILITY

Navistar, Inc. (Navistar) is recalling certain model year 2016 IC Bus RE transit buses manufactured November 12, 2015, to November 16, 2015, equipped with certain model S2005, S2010, S5005, S5010, S5505, and S5510 wheelchair lifts by Ricon. The affected lifts are equipped with folding link arms that may have pivot holes that are too big, allowing the bearings to move out of position.

Risk: If the bearings move out of position, the stowed platform may have excessive movement resulting in failure of the platform mounting. This failure could cause the wheel chair lift platform to fall out of the vehicle when the doors are opened, increasing the risk of injury for the lift operator.

EQUIPMENT ADAPTIVE/MOBILITY

Navistar, Inc. is recalling certain model year 2007-2015 IC BE and CE school buses, 2013-2015 IC AE school buses, 2007-2011 IC FE school buses, and 2007-2014 IC RE school buses equipped with certain model S2005, S2010, S5005, S5010, S5505, and S5510 wheelchair lifts by Ricon. The affected lifts are equipped with folding link arms that may have pivot holes that are too big, allowing the bearings to move out of position.

Risk: If the bearings move out of position, the stowed platform may have excessive movement resulting in failure of the platform mounting. This failure could cause the wheel chair lift platform to fall out of the vehicle when the doors are opened, increasing the risk of injury for the lift operator.

SERVICE BRAKES, AIR

Navistar, Inc. (Navistar) is recalling certain model year 2015 IC RE non-school Transit Buses manufactured November 4, 2014, to November 18, 2014. In the affected vehicles, the air brake hose for the front wheel service brakes may contact the tires when the steering is fully turned.

Risk: Contact with the tire may result in hose abrasion, resulting in an air leak, causing the vehicle to pull to one side when braking and/or requiring extra distance to stop the bus. Either condition may increase the risk of a crash.
