11- Electrical#2022208
9 units affected
Issue: On a small number of buses, the positive battery cable could be damaged by contact with the transmission oil cooler hose. If this happens, the battery cable could short circuit. Safety Risk: A short circuit could create a fire risk. 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 inspect and re-route the positive battery cable.
- Seats And Restraints#2018199
13 units affected
On certain buses equipped with Syntec S3B restraint seats, under extreme operating conditions, such as adverse road conditions, repetitive shock loads, or occupant abuse, a metal fatigue crack may develop on the rear wall mount bracket of the seat. Over time, this could lead to the wall mount bracket fracturing, which in the event of a crash, could increase the risk of injury to seat occupants. Correction: Daimler Trucks of North America Service Facilities will inspect seats and install an additional wall bracket between the wall rail and the seat as necessary.

707 units affected
On certain vehicles equipped with Syntec S3B non-restraint seats, under extreme operating conditions, such as adverse road conditions, repetitive shock loads, or occupant abuse, a metal fatigue crack may develop on the rear wall mount bracket of the seat. Over time, this could lead to the wall mount bracket fracturing, which in the event of a crash, could increase the risk of injury to seat occupants. Correction: Daimler Trucks of North America Service Facilities will inspect seats and install an additional wall bracket between the wall rail and the seat as necessary.

On certain vehicles 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#2016225
1 units affected
On certain 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.
- Heater And Defroster#2016223
6 units affected
On certain buses, the coolant line connected to the heater inside the bus may have been built with a fitting made out of incorrect material. This could restrict coolant flow and lead to premature failure of the elbow, causing a coolant leak inside the bus body. As a result, hot coolant may come in contact with the occupants of the vehicle and cause burn injuries. Correction: Dealers will replace buses built with a rubber elbow with a glass-filled nylon fitting.

3 units affected
On certain 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 2014-338. Vehicles repaired under the previous recall will require re-inspection and potential repair.
- Structure#2015290
145 units affected
On certain buses, the stem which joins the outside emergency door handle to the emergency door opening mechanism may potentially corrode. Excessive material loss of the stem due to corrosion could result in the outside handle separating from the door mechanism while trying to open the door from the exterior of the bus. In the event of an emergency, this could delay evacuation of the vehicle and increase the risk of injury to occupants. Correction: Dealers will inspect the stems and either replace or protect them agianst further corrosion.
- Accessories#2014338
3 units affected
On certain 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.
- Other#2012262
2 units affected
Certain buses fail to comply with the requirements of Canada Motor Vehicle Safety Standard 217 - Bus Window Retention, Release and Emergency Exits. Specifically, the force required to operate the emergency roof hatch may exceed the allowable limit. In the event of an emergency, passengers may not be able to quickly exit the bus, which could increase the risk of personal injuries. Correction: Dealers will install a repair kit to update the roof hatch mechanism.
- Accessories#2011143
8 units affected
On certain vehicles equipped with a Carrier GenV EM-1 evaporator unit, the blower motor fuse assembly may allow the fuse to loosen over time, which could result in high resistance and arcing. If sufficient arcing occurs the fuse holder may melt, which could cause smoke and/or fire. A vehicle fire could result in property damage and/or personal injury. Correction: Carrier will provide a retrofit kit along with installation instructions.
