What's wrong?
The Intellipark PVM on 2024-2025 Ic Bus Cesb and Ce Sbus school buses is part of the parking brake air system. The module uses a rubber ball seal to help control air pressure, so the park brake applies when parked and releases when the bus is ready to move.
In affected modules, the rubber ball seal was improperly molded and can contain cracks. That crack can tear during assembly, then grow into a fracture after repeated use and exposure to heat, cold, and road conditions. Once the seal fractures, the module can develop an excessive air leak, which can lead to park brake failure or unexpected park brake engagement while driving.
Drivers can watch the parking brake control switch LEDs, dashboard telltale, and any audible or visual dash messages for parking brake status. During pre-trip inspection, listen for an excessive air leak; the normal exhaust sound heard when an air-braked bus is parked can also be missing.
Who's affected?
Spans the 2024 Ce Sbus and 2025 Cesb, both tied to the same Intellipark PVM parking-brake 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?
Park brake failure or unexpected park brake engagement while driving increases the risk of a crash. Watch the parking brake switch lights, dashboard telltales, audible alerts, and dash messages. Missing parking air exhaust sounds or an excessive air leak during pre-trip inspection needs dealer attention before the bus is put in service. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2024-2025 Ic Bus Cesb or Ce Sbus is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free Intellipark Park Valve Module replacement that fixes the park-brake leak risk.
- Bring the recall notice if Ic Bus mailed one. If not, reference recall number 24V341 when you call.
- Call Ic Bus customer service at 1-800-448-7825 with questions about scheduling or school bus service status before the repair.
- Use extra caution until the repair is complete, since the park brake can fail or engage unexpectedly while driving.
