Transport Canada recalls

Label#2024423July 24, 2024
1,382 units affected
Issue: On certain school buses, the letters on the instruction labels for the emergency exits are too small. This could make it difficult to read the label. Canadian regulations require a minimum size for the letters. Safety Risk: Instructions for an emergency exit that are difficult to read could delay persons from exiting the bus in an emergency and increase the risk of injury. Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail and advise you to take your school bus to a DTNA authorized service facility to increase the height of the letters on the instruction labels.
Structure#2023540October 3, 2023
1,892 units affected
Issue: On certain school buses, the fasteners for the rear emergency exit door latch could loosen and detach. If this happens, and the door is pushed, it could open suddenly. Safety Risk: An emergency exit door that opens suddenly could increase the risk of injuries. Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail. The corrective actions for this recall are under development. DTNA recommends that you should contact them immediately if you notice any missing bolts during your daily pre-trip inspection.
Powertrain#2021105February 25, 2021
4 units affected
Issue: On a small number of school buses, there may be a software problem with the engine control module. As a result, the engine power may not be reduced when certain safety systems activate, like the traction control system or collision avoidance system. Note: This recall only affects buses equipped with a Cummins B6.7N natural gas engine. Safety Risk: Safety systems that do not work properly could increase the risk of a crash. Corrective Actions: Cummins will notify owners by mail and instruct you to take your bus to a Cummins authorized service center to update the engine control module software.
Electrical#2020078February 26, 2020
292 units affected
Issue: On certain school buses, a software problem could cause the exterior warning lights to stop flashing. If this happens, the red warning lights can turn off suddenly. The stop sign and crossing arm will also retract. Note for drivers: If this happens, the system indicator light will turn off. A driver can press the momentary activation switch to turn the warning lights back on and deploy the stop sign. Safety Risk: If the warning lights stop flashing and the stop sign retracts, other drivers may assume that it is safe to proceed when it is not. This could increase the risk of injury. Corrective Actions: Daimler Trucks North America (DTNA) will notify owners by mail and instruct you to take your bus to a DTNA authorized service facility to update the software in the switch hub module.
Engine#2019611December 6, 2019
106 units affected
Issue: On certain school buses built with a Detroit Diesel DD5 engine, the bolts that attach the engine cooling fan could loosen. If this happens, the fan could detach and/or cause damage to nearby parts. This could disable the school bus. Safety Risk: A bus that is disabled could result in an evacuation in an uncontrolled environment, which may create a risk of injury. Corrective Actions: Daimler Trucks North America (DTNA) will notify owners by mail and instruct them to take their bus to a DTNA authorized service facility to inspect and repair the fan hub fasteners, as required.
Seats And Restraints#2019497October 4, 2019
4,355 units affected
Issue: This recall affects certain school buses equipped with SynTec S3B and/or S3C passenger seats. On some seats, the protective foam in certain areas of the seatback may not meet the knee impact requirements of Canadian regulations. Safety Risk: A seatback that does not have proper knee impact protection could increase the risk of injury to occupants in a crash. Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a Daimler Trucks of North America authorized service facility to install additional protective material in the seatbacks.
Structure#2019362July 24, 2019
149 units affected
Issue: On certain school buses, the outer handle for the roof hatch (emergency exit) could break. If this happens, it would be difficult to open the roof hatch from outside the bus. Safety Risk: An emergency exit that is difficult to open could increase the risk of injury in an emergency. Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a Daimler Trucks North America authorized service facility to replace the roof hatch outer handle.
Electrical#2018735December 21, 2018
423 units affected
On certain school buses, if a short circuit or overload were to occur on the auxiliary port circuit, it could blow the fuse for the ignition circuit. This could result an engine stall without the ability to restart, increasing the risk of a crash causing injury and/or damage to property. Correction: Daimler Trucks of North America Authorized Service Facilities will modify vehicle wiring to ensure that the power port circuit does not affect the ignition circuit.
