Recall 14V215 covers 20 2009-2015 Blue Bird All American buses for intake manifold pressure sensor interference. Authorized Cummins service facilities update the ECM for free.
Blue Bird is recalling 20 2009-2015 All American rear engine non-school buses with Cummins Westport ISL G compressed natural gas engines because condensation can freeze in the intake manifold and disrupt the pressure sensor. That sensor problem can raise exhaust temperatures or send flames from the exhaust pipe, increasing fire and burn-injury risk; the Blue Bird dealer repair will be free once available.

What's wrong?
The intake manifold on the Cummins Westport ISL G compressed natural gas engine is the air passage that feeds the engine before combustion. The intake manifold pressure sensor reads the air pressure inside that passage, then sends that signal to the engine controls so fuel and air delivery stay matched.
On affected 2009-2015 Blue Bird All American buses, moisture collects in the intake manifold. In cold weather, that condensation freezes around the pressure sensor or its sensing path. Once ice blocks or distorts the pressure reading, the engine controls no longer get a clean signal from the manifold. That interferes with proper sensor operation and disrupts how the engine manages combustion.
There is no warning sign before failure. The problem is tied to cold-weather freezing inside the intake system, so an owner or fleet operator should treat rough engine operation or an unexpected engine-control issue in freezing conditions as related until a Blue Bird dealer inspects the bus.

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?
NHTSA campaign 14V215 says improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe. That raises the risk of a vehicle fire or burn injury for anyone standing near the exhaust pipe. Keep people clear of the exhaust area and schedule the recall service soon. Repair will be free at any franchised Blue Bird dealer once available.
What should I do?
- Check your VIN to confirm your 2009-2015 Blue Bird All American is included in this recall.
- Watch for Blue Bird or Cummins owner instructions tied to your VIN before scheduling service.
- Call Blue Bird at 1-478-822-2242 and reference recall number 14V215 when you ask about service.
- Ask whether an authorized Cummins service facility can complete the free ECM calibration that corrects the intake-manifold sensor issue.
- Avoid standing near the exhaust pipe while the engine is running in cold weather until the ECM calibration is complete.
What happens at the repair
At an authorized Cummins service facility, the repair is an ECM calibration update for the Cummins Westport ISL G compressed natural gas engine. The update changes the engine control module software so the intake manifold pressure sensor operates properly in cold weather. The dealer repair will be free once available, with service labor covered under the recall. Use recall number 14V215 when you contact Blue Bird or the service desk.

Frequently asked questions
What is recall 14V215?
Recall 14V215 covers 20 2009-2015 Blue Bird All American rear engine non-school buses with certain Cummins Westport ISL G compressed natural gas engines. Condensation can freeze in cold weather and interfere with the intake manifold pressure sensor. Authorized Cummins service facilities will upload a new ECM calibration for free.
What should I do if my 2009-2015 Blue Bird All American is on this recall?
Check your VIN to confirm your specific bus is included in recall 14V215. If it is, contact Blue Bird or Cummins to arrange the ECM calibration at an authorized Cummins service facility. Reference recall 14V215 or Blue Bird recall number R14XB when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to provide the recall repair at no cost. For recall 14V215, an authorized Cummins service facility will upload the new ECM calibration free of charge.
What is the safety risk?
The intake manifold pressure sensor problem can raise exhaust temperatures or send flames from the exhaust pipe. That increases the risk of a vehicle fire or burn injury to a person standing near the exhaust pipe. The free ECM calibration is the repair path listed for recall 14V215.
What if I bought this Blue Bird All American used?
The free recall repair still applies. Recall eligibility follows the VIN, not the current owner. Check your VIN to confirm whether your specific bus is included, then contact Blue Bird or Cummins with recall 14V215 or Blue Bird recall number R14XB.
