2016 IC BUS CESB

SERVICE BRAKES, HYDRAULIC:FLUID

International Motors, LLC (International) is recalling certain 2016-2024 IC Bus CESB school buses. The brake pressure switch assembly may leak brake fluid into the brake pressure switch's electrical components and cause an electrical short-circuit.

Risk: An electrical short in the brake pressure switch can overheat the circuit and increase the risk of a fire while driving or parked.

SERVICE BRAKES, HYDRAULIC:FLUID

Navistar, Inc. (Navistar) is recalling certain 2016 and 2018-2024 IC Bus CE school buses. The brake pressure switch assembly may leak brake fluid into the brake pressure switch's electrical components and cause an electrical short-circuit.

Risk: An electrical short in the brake pressure switch can overheat the circuit and increase the risk of a fire while driving or parked.

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.

FUEL SYSTEM, OTHER:DELIVERY:FUEL PUMP

Navistar, Inc. (Navistar) is recalling certain 2016-2019 IC bus CE school buses equipped with 8.8L liquid propane gas (LPG) engines. The LPDM relay for the propane booster pump and the scavenge pump may intermittently fail, causing the fuel pump to stop.

Risk: If the fuel pump stops, the bus will stall, increasing the risk of a crash.

EQUIPMENT ADAPTIVE/MOBILITY

Navistar, Inc. (Navistar) is recalling certain 2015-2019 IC Bus CE school buses, equipped with certain S-Series and K-Series Titanium Wheelchair Lifts, models K200, K201, K550, K551, S200, S2201, S550 and S551. The wheelchair lift positioning input cam may fail while the lift is in use, allowing the platform to travel higher than the vehicle's floor height.

Risk: If the wheelchair lift platform stops above the vehicle floor, the wheelchair user can tip inwards toward the vehicle when exiting the lift, increasing their risk of injury.

ELECTRICAL SYSTEM

Navistar, Inc. (Navistar) is recalling certain 2016-2018 IC Bus CE school buses equipped with a plastic booster pump, 17k Webasto heater and a Webasto Smart Temp timer. The power circuit for the heater booster pump may be unfused.

Risk: Without circuit protection, if the vehicle has a heater booster pump electrical failure, it can increase the risk of a fire.

STEERING

Navistar, Inc. (Navistar) is recalling certain 2016 IC Bus CE school buses equipped with certain Spicer D or E series steer axles. The castellated nut on the steer axles may not be properly torqued, allowing the tie rod to loosen.

Risk: If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering, increasing the risk of a crash.

STRUCTURE:BODY:HOOD:HINGE AND ATTACHMENTS

Navistar, Inc. is recalling certain model year 2016-2017 IC CE school buses manufactured from November 24, 2014, through January 22, 2016. In the affected vehicles, the hood straps used to latch the hood closed may become elongated and not return to their original length. As a result, the hood may open unexpectedly when the bus is braking.

Risk: If the hood opens while braking, the driver's vision may be obstructed, increasing the risk of a crash.

EQUIPMENT ADAPTIVE/MOBILITY

Navistar, Inc. (Navistar) is recalling certain model year 2015 IC Bus AE and BE, 2015-2017 CE and 2016-2017 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.

OTHER:SCHOOL BUS STOP ARM ASSEMBLY

Navistar, Inc. (Navistar) is recalling certain model year 2016-2017 IC CE school buses manufactured May 4, 2015, to December 15, 2015, and 2016 IC RE school buses manufactured July 17, 2015, to December 15, 2015, and equipped with certain Transpec T6000, T6100, and T7000 series school bus stop arms. The affected stop arms have a reflective decal that may peel loose from the stop arm. As such, these stop arms fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 131, "School Bus Pedestrian Safety Devices."

Risk: Without a reflective decal, the stop arms would have reduced visibility to other drivers, increasing the risk of a crash.

ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS

Navistar, Inc. (Navistar) is recalling certain model year 2011-2016 IC Bus CE school buses manufactured November 3, 2009, to February 26, 2015, and 2012-2015 IC Bus BE school buses manufactured August 2, 2010, to September 15, 2014. The affected vehicles have a water shutoff valve, inside, forward of driver heater (feature code 48PPJ or 48PPP) that has a formed heater hose that over time, may fatigue and split resulting in hot engine coolant fluid leaking into the driver's foot area.

Risk: If hot, pressurized coolant suddenly spills into the operator's foot area, there is an increased risk of a burn injury or a crash.

STRUCTURE:EMERGENCY:ESCAPE/EGRESS/EXIT

Navistar, Inc. (Navistar) is recalling certain 2016-2017 IC Bus CE school buses manufactured June 15, 2015, to May 20, 2016, and RE school buses manufactured June 18, 2015, to April 27, 2016. These buses may have been manufactured without reflective outline tape around the emergency exit roof hatches. As a result, these vehicles fail to comply with the requirements for Federal Motor Vehicle Safety Standard (FMVSS) number 217, "Bus Emergency Exits and Window Retention and Release."

Risk: Absence of the reflective outline tape may reduce conspicuity of the emergency exit roof hatches, reducing the ability of emergency personnel to identify and gain access to the emergency roof hatches, possibly increasing the passenger's risk of personal injury or death during an emergency.

FUEL SYSTEM, DIESEL

Navistar, Inc. (Navistar) is recalling certain model year 2015-2016 IC CE school buses manufactured October 3, 2013, to March 16, 2015. In the affected school buses, the powertrain wiring harness may contact the high pressure fuel line for one of the fuel injectors, possibly resulting in a fuel leak.

Risk: If the high pressure fuel line leaks, fuel may spray into the engine compartment, increasing the risk of a fire.
