Recall 14V517 affects 370 2012-2014 Nabi 40LFW and 31LFW transit buses for CNG tank abrasion. Free cover at a Nabi dealer, permanent repair once available.
Nabi is recalling 370 2012-2014 40LFW and 31LFW transit buses because pressure relief devices in the compressed natural gas fuel system can rub against nearby CNG tanks. That contact can cause a CNG leak and increase the risk of a fire; the dealer repair will be free once Nabi makes it available.

What's wrong?
The affected Nabi 40LFW and 31LFW buses use a Compressed Natural Gas fuel system. The CNG tanks store fuel under high pressure, and the pressure relief devices are safety parts mounted near those tanks. Their normal job is to vent pressure if the tank area overheats or pressure rises beyond the design limit.
On these buses, the pressure relief devices sit close enough to the CNG tanks to rub against them. That contact abrades the outside of the tank, which means it wears away the tank surface during normal vehicle movement. A CNG tank is a pressure vessel, so surface damage is not cosmetic. It needs dealer inspection and repair through the recall process.
There is no warning sign before failure. An owner or fleet operator should not wait for a smell, noise, warning light, or driveability change to confirm this problem.

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?
Contact between the pressure relief device and the tank can create a CNG leak, which increases the risk of fire. Schedule the recall work soon, and ask the dealer how to handle the bus until the remedy is completed. Repair will be free at any franchised Nabi dealer once available.
What should I do?
- Check your VIN to confirm your 2012-2014 Nabi 40LFW or 31LFW bus is included in this recall.
- Contact a franchised Nabi dealer and ask for the temporary PRD cover that separates the pressure-relief device from the CNG tank.
- Reference recall number 14V517 when you call, and ask whether Nabi recall 20145 applies to your bus.
- Watch for Nabi's second notice before scheduling the permanent Agility fuel-system repair.
- Keep the bus away from ignition sources and stop using it if you smell CNG or suspect a fuel leak.
What happens at the repair
Nabi's remedy called for owners to be notified before dealer work. At the dealer, a Nabi technician installs a temporary flexible cover over the pressure relief device to reduce contact with the CNG fuel tank. Agility was still developing the permanent improvement, and owners were to receive another notice when that final remedy became available. The final dealer repair is covered under the recall once available.
