03- Accessories#2016418
35 units affected
On certain school buses equipped with a Ricon S-Series wheelchair lift, the platform could potentially crack due to bent knuckle link arms and/or defective bearing. Overtime, the platform could separate of the rear portion of the pivot plate making the lift inoperable and putting the lift operator at risk of injury. Correction: Owners will need to make an appointment with the local Ricon Dealer to have the lift inspected and repaired.
- Structure#2015291
8,093 units affected
On certain school 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 against further corrosion.
- Heater And Defroster#2010143
43 units affected
On certain buses, a heater coolant flow valve actuator O-ring may allow coolant leakage into the heater core compartment and the actuator Printed Circuit (PC) board area, potentially causing overheat and melt. An overheated and/or melted actuator may result in a vehicle fire causing property damage, personal injury or death. Correction: Dealers will replace the dash heater actuator with a more robust version.
