What's wrong?
On the 2008-2014 New Flyer C40LF, C40LFR, C35LF, C35LFR, XN40, XN60, XN35, and L40LFR buses in NHTSA campaign 15V292, the issue is in the engine crankcase ventilation system. That system vents pressure from inside the engine crankcase, where moving engine parts churn oil and air while the engine runs. The vent tube assembly includes a 90-degree elbow that connects to the crankcase ventilation breather.
On affected buses with Cummins Westport ISL G engines, excessive crankcase pressure can force that 90-degree elbow loose. Once the elbow detaches, the vent path no longer stays connected at the breather. Engine oil can then escape from the ventilation assembly and contact hot engine surfaces.
The filing does not identify a driver warning sign before the elbow separates. There is no warning sign before failure.

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?
This recall involves engine oil that can reach hot surfaces and raise the risk of a vehicle fire. If your vehicle is included, schedule the repair soon and follow service guidance until the work is complete. Repair is free at any franchised New Flyer dealer.
What should I do?
- Check your VIN to confirm your 2008-2014 New Flyer C40LF, C40LFR, C35LF, C35LFR, XN40, XN60, XN35, or L40LFR bus is included in this recall.
- Contact New Flyer customer service at (204) 224-6706 to schedule the free repair through the Cummins service network.
- Schedule the vent-tube elbow securing and ECM reprogramming that limits crankcase pressure and keeps engine oil away from hot surfaces.
- Bring the recall notice if New Flyer or Cummins has mailed one. If not, reference recall number 15V292 and New Flyer recall R15-007 when you call.
- Keep the bus out of service if you smell engine oil, see oil leakage, or see smoke near hot engine surfaces before the repair.
What happens at the repair
At the service center, a New Flyer technician secures the ends of the 90-degree elbow in the crankcase ventilation breather assembly. The technician also reprograms the electronic control module with software that adjusts engine output under misfire conditions to limit crankcase pressure. Parts and labor are covered under the recall. New Flyer's reimbursement plan covers documented out-of-pocket repairs tied to this defect before the recall repair. Bring repair records and payment documentation when you ask about reimbursement.
