Ic Bus is recalling 457 2016-2026 Cesb and Resb school buses because the underfloor reinforcement was omitted on affected buses, reducing structural integrity and leaving them out of compliance with federal seating and seat belt anchorage rules. Reduced structural integrity increases the risk of injury in a crash, and Ic Bus dealers will install the reinforcement free of charge.

What's wrong?
The floor side reinforcement is a structural support installed under the bus floor. On 2016-2026 Ic Bus Cesb and Resb school buses, it supports areas near the side emergency door, luggage compartment, and dual riser seat. Its job is to help the bus body hold seat belt anchorages and passenger seating in place during a crash load.
Under NHTSA campaign 25V580, affected buses were built without that reinforcement where the floor plan required it. That leaves the floor structure short of the required support for seat belt anchorage and school bus passenger seating protection. The issue is a structural noncompliance, not a loose trim part or normal wear item.
There is no warning sign before failure. A missing underfloor reinforcement is not something a driver can see from the seat, and normal driving does not give a clear symptom that the support is absent.

What's the safety risk?

What happens at the repair
At the dealer, an Ic Bus technician inspects the underfloor reinforcement area and installs a reinforcement channel where the bus needs it. The recall repair, including parts and labor, is free. The manufacturer used its general reimbursement plan for campaign 25V580, so documented out-of-pocket repairs tied to this defect can be reviewed for reimbursement. Bring repair invoices and payment records to the service desk or contact International customer service before the appointment.
