Recall 14V081 affects 269 2013-2014 Nabi Lfw and Brt transit buses for intake-manifold condensation that freezes. Repair is free at any franchised Nabi dealer.
Nabi is recalling 269 2013-2014 Lfw and Brt city transit buses because condensation in the intake manifold can freeze in cold weather and interfere with the intake manifold pressure sensor. The sensor problem can lead to elevated exhaust temperatures or flames from the exhaust pipe, raising the risk of fire or burn injury; the dealer repair will be free once available.

What's wrong?
The intake manifold on 2013-2014 Nabi Lfw and Brt city transit buses routes air into the engine so fuel can burn correctly. The intake manifold pressure sensor reads air pressure inside that passage and sends the engine computer the information it needs to manage engine operation.
On affected buses with the Cummins Westport Model ISL G engine, condensation can collect inside the intake manifold. In cold weather, that moisture can freeze around the pressure sensor and interfere with its reading. When the sensor cannot read manifold pressure correctly, the engine computer is working from bad information, so proper engine operation is disrupted.
There is no warning sign before failure. An operator or maintenance shop should treat cold-weather intake or sensor problems on these buses as recall-related until a Nabi service desk or franchised service provider checks the VIN and engine configuration.
Who's affected?
Covers Lfw and Brt buses from the 2013 and 2014 model years, both tied to the engine component.
| 2013 Nabi Lfw | Engine |
|---|---|
| 2013 Nabi Brt | Engine |
| 2014 Nabi Brt | Engine |
| 2014 Nabi Lfw | Engine |
| Units affected | 269 |
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?
Improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to someone standing near the exhaust. Keep people away from the exhaust area and contact the dealer for repair timing. Repair will be free at any franchised Nabi dealer once available.
What should I do?
- Check your VIN to confirm your 2013-2014 Nabi Lfw or Brt bus is included in this recall.
- Contact Nabi customer service before scheduling service, since the remedy status is not listed as open in this record.
- Reference recall number 14V081 and Nabi recall 20141 when you call.
- Ask about the free ECM calibration that corrects the intake-manifold sensor problem linked to elevated exhaust temperatures or flames from the exhaust pipe.
- Keep people clear of the exhaust area until the bus has been inspected and the ECM calibration is complete.
What happens at the repair
At the dealer, a Nabi technician uploads a new engine control module calibration for the Cummins Westport ISL G engine. The calibration addresses intake manifold condensation that can freeze in cold weather and interfere with the intake manifold pressure sensor. Before scheduling, ask the dealer to confirm that the recall repair is open for your VIN. The final dealer repair will be free once available.

Frequently asked questions
What is recall 14V081?
Recall 14V081 covers 269 2013-2014 Nabi Lfw and Brt city transit buses with certain Cummins Westport ISL G engines. Condensation in the intake manifold can freeze in cold weather and interfere with the intake manifold pressure sensor. Dealers will upload a new ECM calibration for free.
What should I do if my 2013-2014 Nabi Lfw or Brt is on this recall?
Check your VIN to confirm your specific bus is included in recall 14V081. If it is, contact a franchised Nabi dealer or Nabi customer service at 1-256-831-4926 to schedule the free ECM calibration update. Reference recall number 14V081 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and the remedy for recall 14V081 is a free ECM calibration upload. The recall began on April 21, 2014, so the dealer repair path is open.
What is the safety risk?
The safety risk in recall 14V081 is fire or burn injury near the exhaust pipe. When the sensor operates improperly, the engine can produce elevated exhaust temperatures or flames from the exhaust pipe. The free ECM calibration update is the repair path for included buses.
What warning signs should I watch for?
The filing points to cold weather as the condition tied to the defect. Condensation in the intake manifold can freeze and interfere with the intake manifold pressure sensor. Treat exhaust flames, abnormal exhaust heat, or related engine warnings as service issues and confirm the VIN before continued operation.
