What's wrong?
The fuel filter on the 2015 Ic Bus Casb school bus sits in the diesel fuel system between the tank and the engine. Its job is to screen contaminants out of the fuel before that fuel reaches the Cummins ISB or ISL engine, so the engine gets a steady supply of clean diesel.
On the recalled buses, the Fleetguard UFF-XT fuel filter, part number FF63009, has a shell that can separate from the fuel filter nut plate. That separation breaks the filter assembly instead of keeping it sealed. Once that happens, fuel delivery to the engine is interrupted and the engine stalls.
There is no warning sign before failure. The stall can happen while the bus is in use, so an owner or fleet operator should treat the filter issue as a mechanical defect in the fuel system, not as normal engine hesitation.

What's the safety risk?
An unexpected engine stall can leave the bus without power in traffic and increase the risk of a crash. Schedule the recall repair soon, and if the engine stalls, steer out of traffic when safe and stop the bus. Repair will be free at any franchised Ic Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2015 Ic Bus Casb is included in this recall.
- Wait for Ic Bus or Cummins owner notification before scheduling the dealer repair, unless a franchised Ic Bus dealer confirms the repair is open for your VIN.
- Call Ic Bus customer service at 1-800-448-7825 with questions and reference recall number 14V573 when you call.
- Ask the dealer about the free fuel-filter replacement that fixes the filter-shell separation tied to engine stalling.
- Avoid driving routes where an unexpected engine stall would create extra risk until the fuel-filter replacement is complete.
What happens at the repair
The notification schedule has not been provided, so do not treat the final dealer visit as schedulable from this notice alone. Once the recall work is available, an Ic Bus technician replaces the defective Fleetguard fuel filter with a non-defective filter. The recall repair is free, with parts and labor covered. The repair is meant to address a filter shell that can separate from the fuel filter nut plate and cause the engine to stall without warning.
