What's wrong?
The turbocharger on the 2005-2006 New Flyer C40LF and C40LFR buses is part of the John Deere 8.1 liter compressed natural gas engine, model 6081HFN04. It uses exhaust flow to spin internal wheels, then pushes more air into the engine so the fuel burns properly and the bus maintains power.
Inside the turbocharger, the turbine wheel and compressor wheel spin at high speed on a shared shaft. On affected buses, a failure can occur inside that assembly. If the turbine or compressor wheel breaks, pieces can damage the engine and the failure can also lead to an oil leak.
There is no warning sign before failure. That means the driver cannot count on a light, sound, or change in how the bus feels to identify the problem before the turbocharger fails.
Who's affected?
Covers C40LF and C40LFR buses across the 2005 and 2006 model years; both use the same turbo/supercharger component.

| Units affected | 163 |
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?
A turbine or compressor wheel failure creates smoke, fire, or stalling risk and raises the risk of a crash. If smoke appears or the vehicle stalls, stop in a safe place and contact New Flyer service before putting it back in use. Repair will be free at any franchised New Flyer dealer once available.
What should I do?
- Check your VIN to confirm your 2005-2006 New Flyer C40LF or C40LFR is included in this recall.
- Contact New Flyer customer service for current interim instructions because the final remedy is not open yet.
- Ask New Flyer when the free turbocharger repair will open and reference recall number 12V466 when you call.
- Inspect for smoke, oil leakage, turbocharger noise, or engine stalling before dispatch, and pull the bus from service if any sign appears.
- Keep the interim owner letter with the bus maintenance file and bring it when New Flyer gives final repair instructions.
What happens at the repair
At the dealer, a New Flyer technician will complete the final repair once New Flyer releases the remedy for the turbocharger failure issue. The recall filing says the remedy was still under development, so do not assume the final repair is ready to schedule until New Flyer or the dealer confirms it. An interim owner letter was mailed on October 3, 2012, and owners were directed to contact New Flyer at 1-204-224-1251. The final dealer repair will be free once available.
