What's wrong?
The engine turbo oil supply line on the 2011 Ic Bus Ce school bus carries pressurized engine oil to the turbocharger. The turbocharger uses exhaust flow to help the engine move more air, and it depends on a steady oil supply for lubrication and cooling. That oil line has to stay routed away from hard metal edges while the bus runs and vibrates.
On affected buses, the turbo oil supply line can rub against the frame rail, the heavy side rail that forms part of the bus structure. That contact wears on the line over time. If the line is damaged, engine oil leaks into the engine compartment instead of staying inside the lubrication system.
There is no warning sign before failure. The first sign can be oil in the engine compartment after the line has already started leaking, so inspection and the recall repair matter even when the bus seems to run normally.

Not every 2011 Ic Bus Ce bus is on the list. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
An oil leak in the engine compartment creates a fire risk. No warning sign is listed before that risk develops, so treat any visible oil leak or oil odor as a reason to stop using the bus and call the dealer. Repair will be free at any franchised Ic Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2011 Ic Bus Ce is included in this recall.
- Contact Ic Bus customer service at 1-800-448-7825 before scheduling service to confirm the repair path.
- Schedule the free engine turbo oil supply line repair with a franchised Ic Bus dealer once Ic Bus confirms service instructions.
- Reference recall number 10V574 when you call, and bring the recall notice if you have it.
- Park the bus away from structures and avoid running the engine if you see or smell oil in the engine compartment.
What happens at the repair
At the dealer, an Ic Bus technician checks the engine turbo oil supply line where it can rub against the frame rail, then performs the recall repair needed to stop that contact and reduce the chance of an engine compartment oil leak. The filing does not name a specific replacement part or labor time. Because the remedy status is not listed as available, the final dealer repair should be treated as free once Ic Bus opens it for this campaign. Parts and labor are covered under the recall.
