Recall 15V485 covers 70 2014-2015 Nabi 40LFW and 42BRT buses for CNG pressure relief devices that fail to vent. Free at a franchised Nabi dealer.
Nabi is recalling 70 2014-2015 40LFW and 42BRT CNG transit buses under recall 15V485 because the pressure relief devices on the fuel tanks can fail to vent pressure. If pressure builds and the device does not open, the tank can explode and increase the risk of fire and injury; Nabi dealers will complete the repair free of charge.

What's wrong?
The affected 2014-2015 Nabi 40LFW and 42BRT buses use compressed natural gas stored in high pressure tanks. A pressure relief device is a safety valve on that tank system. Its job is to open and vent gas if tank pressure rises, including during a fire, so pressure does not keep building inside the tank.
On these buses, the Emcara pressure relief devices were manufactured incorrectly. Because of that defect, the valve can fail to open as designed when the CNG tank needs to vent. The issue is tied to recalled devices with component serial numbers from 1119 to 39000; replacement devices are outside that range.
There is no warning sign before failure. The device sits in the fuel storage system and is not something a driver will feel through normal braking, steering, or engine operation.

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 pressure relief device that fails during pressure buildup leaves the CNG tank without its intended safety vent. That pressure buildup can cause the tank to explode, increasing the risk of fire and injury. There is no warning sign before failure, so schedule the recall repair soon. Repair is free at any franchised Nabi dealer.
What should I do?
- Check your VIN to confirm your 2014-2015 Nabi 40LFW or 42BRT bus is included in this recall.
- Contact a franchised Nabi dealer to schedule the free pressure-relief-device replacement that lets the CNG tank vent excess pressure.
- Bring the recall notice if you have it. If not, reference recall number 15V485 when you call.
- Keep the bus away from fire exposure until the PRD replacement is complete.
What happens at the repair
At the service appointment, a Nabi technician works with Agility, the CNG system supplier, to replace the pressure relief devices in the compressed natural gas system. The PRDs are the parts designed to vent excess tank pressure. Replacement parts and labor are free under recall 15V485. The recall remedy is available now, so affected bus operators can arrange the repair through Nabi service.

Frequently asked questions
What is recall 15V485?
Recall 15V485 covers 70 2014-2015 Nabi 40LFW and 42BRT CNG transit buses with pressure relief devices that can fail to vent pressure from the CNG tank. If pressure builds and the device fails to open, the tank can explode, increasing the risk of fire and injury.
What should I do if my 2014-2015 Nabi 40LFW or 42BRT is on this recall?
Check your VIN to confirm whether your specific bus is included in recall 15V485. If it is, contact the Nabi service channel or call 1-204-224-1251 and reference recall R15-012. Agility, the CNG system supplier, replaces the pressure relief devices for free.
Is the recall repair free?
Yes. Federal recall law requires the defect repair at no cost, and the remedy for recall 15V485 is free. Agility replaces the affected CNG pressure relief devices, with the repair handled through the Nabi recall service process.
What is the safety risk for this Nabi CNG bus recall?
The safety risk is a CNG tank pressure event. If the pressure relief device fails during pressure buildup, including exposure to fire, the tank can explode. That increases the risk of fire and injury. Confirm the VIN, then arrange the free PRD replacement.
