What's wrong?
The windshield wiper module on the 2026 Ic Bus Cesb school bus is the powered assembly that moves the wiper arms across the glass. Its crank shaft assembly turns motor movement into the back-and-forth sweep that clears rain, snow, and road spray from the driver's view. The left-side wiper depends on that crank shaft weld staying intact.
On affected buses, the crank shaft assembly in some CVG wiper modules was not welded properly. If the weld fails, the mechanism no longer transfers motion to the left-side wiper arm. The motor and module can still be present, but the left-side blade does not wipe the windshield as designed.
There is no warning sign before failure. The driver would notice the problem when the left-side wiper stops moving or fails to clear the windshield during use.

What's the safety risk?
An inoperative wiper reduces the driver's view through the windshield and increases crash risk, especially in rain, snow, or road spray. If the wiper stops working, limit driving in poor visibility and arrange service soon. Repair will be free at any franchised Ic Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2026 Ic Bus Cesb is included in this recall.
- Watch for Ic Bus repair instructions if your bus is included; owner letters were mailed October 27, 2025.
- Call Ic Bus customer service at 1-800-448-7825 and reference recall number 25V640.
- Ask a franchised Ic Bus dealer about the windshield-wiper-module inspection and replacement that fixes the left-side wiper failure.
- Keep the bus out of service in rain, snow, or low-visibility conditions until the wiper repair is complete.
What happens at the repair
At the dealer, once the remedy is available, an Ic Bus technician will inspect the windshield wiper module and replace it if needed. The final dealer repair will be free once International opens the remedy. The issue involves the crank shaft assembly weld for the left side wiper, so the inspection focuses on the wiper module that controls that function. International uses its standard reimbursement plan for this recall. If you already paid for a related wiper module repair, ask the service desk or International customer service how to submit documentation for reimbursement.
