Blue Bird is recalling 32 2013-2014 All American school buses with compressed natural gas systems in Colorado, Pennsylvania, Utah, and Wyoming because a cold-temperature O-ring failure in the pressure relief device can allow a natural gas leak. A leak near an ignition source raises the risk of fire or explosion, and the Blue Bird dealer repair will be free once available.

What's wrong?
The 2013-2014 Blue Bird All American buses in this recall use a compressed natural gas fuel system. The pressure relief device is a safety valve on the CNG tank assembly. Its job is to release excess pressure from the tank under controlled conditions, while seals inside the device keep gas contained during normal operation.
On affected buses, an O-ring inside that pressure relief device fails in cold temperatures. The O-ring is a small rubber seal, and when it no longer seals correctly, natural gas escapes from the CNG system. This recall is tied to buses delivered to or registered in Colorado, Pennsylvania, Utah, and Wyoming, where cold conditions expose the weak seal.
There is no warning sign before failure. The problem is inside the pressure relief device, so the safest assumption is that the seal fails without giving the driver a clear advance signal.

What's the safety risk?
A natural gas leak near an ignition source creates a fire or explosion risk. If you suspect a leak, stop using ignition sources nearby and contact the dealer promptly. Repair will be free at any franchised Blue Bird dealer once available.
What should I do?
- Check your VIN to confirm your 2013-2014 Blue Bird All American is included in this recall.
- Contact a franchised Blue Bird dealer or service center and ask whether the free CNG pressure-relief-device repair is open for your bus.
- Schedule the pressure relief device and O-ring replacement that fixes the CNG leak path in cold weather.
- Bring the recall notice if Blue Bird mailed one. If not, reference recall number 14V436 when you call.
- Keep the bus away from ignition sources and report any natural gas smell to the dealer before moving it.
What happens at the repair
At the dealer, a Blue Bird technician replaces the original pressure relief device and O-ring in the compressed natural gas system with a new pressure relief device and O-ring. The work addresses the seal failure described in recall 14V436, which can lead to a natural gas leak in cold temperatures. The final dealer repair will be free once available. Parts and labor are covered under the recall.
