What's wrong?
The emergency exit windows and doors on 2014, 2019, and 2022 Ic Bus Casb and Cesb school buses are the extra ways passengers leave the bus when the main door is not usable. They release from the frame so passengers and the driver have more than one path out during an emergency.
On the 33 affected buses, the floor plan left the bus short of the minimum emergency exit openings required for its passenger capacity. Some 77 passenger buses counted the driver and reached a total capacity of 78, but the exit capacity did not exceed that total. Two 45 passenger buses also lacked the required left side emergency door or emergency windows.
This is a build configuration problem, not a wear item that breaks over time. There is no warning sign before failure.
Who's affected?
Covers Casb and Cesb buses from the 2014, 2019, and 2022 model years, all tied to the same passenger emergency-exit window component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Missing emergency exit windows can slow passenger evacuation during an emergency, increasing the risk of injury. There is no warning sign before this risk matters, because the issue is the vehicle's exit layout. If your VIN is included, schedule the repair soon and ask the dealer how quickly the added exit windows can be installed. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2014, 2019, 2022 Ic Bus Casb or Cesb is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free emergency-exit-window installation that adds the missing exits.
- Bring the recall notice Ic Bus mailed, or reference recall number 21V450 and Ic Bus recall 21506 when you call.
- Plan service before using the bus for passenger service if the VIN is included and the repair is still open.
What happens at the repair
At the dealer, an Ic Bus technician installs two additional emergency exit windows so the bus has the required emergency exits and window release equipment. The recall repair is free, with parts and labor covered. Navistar's standard reimbursement plan applies to eligible repairs paid before the owner notice, and reimbursement instructions were included in the customer notification. If you have prior repair paperwork, ask the service desk or Navistar customer service how to submit it under that plan.
