11- Seats And Restraints#2023301
14 units affected
Issue: On certain school bus seats, the plastic trim (bezel) where the shoulder seat belt comes out of the seatback may be too hard. Canadian regulations have requirements for anything that is installed in certain areas of the seatback. Note: This only affects school buses equipped with certain Syntec M2K and S3C passenger seats with lap/shoulder seat belts. Safety Risk: While this plastic trim is doesn't technically meet the requirements of Canadian regulations, it's unlikely to cause an injury. Corrective Actions: This is not a recall. The company made changes in 2017, and all new seats made after that time have a soft vinyl cover trim for the shoulder seat belt.
- Seats And Restraints#2022680
51 units affected
Issue: On certain school buses, the restraining barrier between the entrance door and the first seat may not meet the energy absorption requirements of Canadian regulations. Safety Risk: A barrier that does not properly absorb energy could increase the risk of injury to passengers in a crash. Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail. The corrective actions for this recall are under development.
- Structure#2022577
284 units affected
Issue: Certain school buses may not meet Canadian regulations for roof panel joint strength. Safety Risk: A roof joint that is not strong enough could increase the risk of injury in a crash. Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail and instruct you to take your bus to a DTNA authorized service facility to add additional fasteners to the roof lap joints.

- Accessories#2018028
12,791 units affected
On certain school buses equipped with Kidde fire extinguishers with black plastic handles and valves, the fire extinguishers may become clogged or require excessive force to activate. Also, the nozzle may detach from the valve assembly with enough force that it could cause injury, and fail to discharge. In case of fire, failure of the extinguisher to function could result in injury and/or property damage. Correction: Owners will be provided with instructions on how to inspect the fire extinguisher to see if it is recalled. Replacement fire extinguishers will be supplied by Kidde directly. Note: For more information about recalled fire extinguishers, please visit <a href="https://inmarmarketaction.com/kidde/Kidde284CA/">www.kidde.com</a>.
- Heater And Defroster#2016224
2 units affected
On certain school buses equipped with a transmission retarder, a bypass fitting may locally increase the coolant system pressures beyond the application working pressure of the standard heater hoses. The maximum pressures do not exceed the burst-pressure of the hose but, over time hose fatigue may occur and lead to a premature failure of the heater hose. If the hose were to fail, it may lead to a coolant leak inside the bus body, which may come in contact with the occupants of the vehicle and cause burn injuries. Correction: Dealers will replace the affected heater hose.
- Accessories#2015395
173 units affected
On certain school buses equipped with a Ricon wheelchair lift, the lift platform sides may crack, which could cause the lift to lean against the vehicle door(s) and potentially fall out of the vehicle when the doors are opened, putting the lift operator at risk of injury. Correction: Ricon Corporation repair facilities will inspect lift platforms, link arms and bearings for cracks, damage or misalignment and if found to be damaged, link arms and/or platform will be replaced. Note: This recall supersedes recall 2014-330. Vehicles repaired under the previous recall will require re-inspection and potential repair.
- Engine#2015335
14 units affected
On certain school buses equipped with Cummins Westport ISL-G engines, excessive engine crankcase pressure could cause the vent tube assembly molded rubber adapter to detach from the breather. This could allow engine oil to come in contact with hot surfaces, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will install clamps at both ends of the adapter of the breather tube assembly and reprogram the Electronic Control Module (ECM) to improve diagnostic capabilities.
- Accessories#2014330
173 units affected
On certain school buses equipped with a Ricon wheelchair lift, the lift platform sides may crack, which could cause the lift to lean against the vehicle door(s) and potentially fall out of the vehicle when the doors are opened, putting the lift operator at risk of injury. Correction: Ricon Corporation repair facilities will inspect lift platforms for cracks and repair as necessary, and install a repair kit.
- Engine#2014051
15 units affected
On certain vehicles equipped with Cummins ISL G or ISX12 G engines, incorrect engine ECU programming could cause the exhaust system temperature to become elevated during cold weather operation. This could also cause flames to be emitted from the exhaust. As a result, nearby combustible material could be ignited, increasing the risk of a fire, injury and/or damage to property. Correction: Authorized Cummins service facilities will update software programming.
- Fuel System#2013281
28 units affected
On certain school buses, an information label may detach from the auxiliary heater fuel pickup tube and block the engine fuel suction tube, which could restrict or stop the flow of fuel to the engine. Engine stalling would result in a loss of vehicle propulsion which, in conjunction with traffic and road condition and the driver’s reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will inspect the fuel tank. If a label is found, it will be removed from the tank.
