Safety recall notices and repair campaigns registered for the 2012 Thomas Built Saf-T-Liner Hdx School Bus in Canada.
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.
A barrier that does not properly absorb energy could increase the risk of injury to passengers in a crash.
Daimler Truck North America (DTNA) will notify owners by mail. The corrective actions for this recall are under development.
Certain school buses may not meet Canadian regulations for roof panel joint strength.
A roof joint that is not strong enough could increase the risk of injury in a crash.
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.
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.
A barrier that does not properly absorb energy could increase the risk of injury to passengers in a crash.
Daimler Trucks North America (DTNA) will notify owners by mail. The corrective actions for this recall are under development.
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 www.kidde.com.
A failure of this component (accessories) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
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.
A failure of this component (heater and defroster) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
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.

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.
A failure of this component (engine) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
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.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
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.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain school buses equipped with a Cummins engine, the V-band clamps used to connect the inlet and outlet cone sections to the Diesel Oxidation Catalyst (DOC) / Diesel Particulate Filter (DPF) include a T-bolt which can fracture and fail when subjected to stress or load. A fracture or failure of the T-bolt may cause the clamp to loosen and the inlet or outlet sections attached to the DOC/DPF housing to disconnect. Should this occur, hot exhaust gases can vent prior to exiting the tailpipe, creating a risk of combustion or damage to adjacent materials, which could result in a vehicle fire. If both clamps fail, the DOC/DPF housing could detach completely, separate from the vehicle, and strike another vehicle, stationary object, or bystander. These issues could result in property damage and/or personal injury. Correction: Cummins will install updated V-band clamps.
