Recall 14V143 affects 241 2013-2014 Nabi 40LFW, 35LFW, and 31LFW buses for CNG cover latch interference. Repair is free at any franchised Nabi dealer.
Nabi is recalling 241 2013-2014 40LFW, 35LFW, and 31LFW transit buses with CNG fuel systems because a latch bolt for the top cover can contact the CNG fuel cylinder. That contact can damage the cylinder, cause a fuel leak, and raise the risk of fire; the dealer repair will be free once available.

What's wrong?
The CNG fuel system on these 2013-2014 Nabi 40LFW, 35LFW, and 31LFW buses stores compressed natural gas in roof-mounted fuel cylinders. Those cylinders hold fuel under pressure, and the top covers are supposed to close over them so the tanks stay protected while the bus is in service. A latch assembly keeps each cover secured.
The defect is in that latch area. A bolt on the latch assembly that holds the CNG top covers closed is positioned so it contacts the CNG fuel cylinder. The bolt is a hard fastening part, so contact with the cylinder puts pressure on a surface that should stay clear of nearby hardware.
There is no warning sign before failure. An owner or fleet technician should not expect a dashboard light, sound, or change in bus operation to confirm that the latch bolt is touching the CNG fuel cylinder.
Who's affected?
Covers the 31LFW, 35LFW, and 40LFW bus models across the 2013 and 2014 model years, all tied to the same fuel system component.

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?
Bolt contact with the CNG cylinder risks damage to the fuel cylinder. Damage to that cylinder creates a fuel leak risk and increases the risk of a fire. If your VIN is included, schedule the recall repair soon and ask the dealer whether the vehicle needs inspection before service. Repair will be free at any franchised Nabi dealer once available.
What should I do?
- Check your VIN to confirm your 2013-2014 Nabi 40LFW, 35LFW, or 31LFW bus is included in this recall.
- Contact a franchised Nabi dealer to ask whether the free interference repair is open for your VIN.
- Schedule the free interference repair that keeps the CNG top-cover latch bolt from contacting the fuel cylinder.
- Bring the owner notice if you have it, or reference recall number 14V143 and Nabi recall 20142 when you call.
- Park the bus away from ignition sources if you smell fuel or suspect a CNG fuel leak.
What happens at the repair
What is known: Nabi dealers are instructed to eliminate the interference between the latch assembly bolt for the CNG top covers and the CNG fuel cylinder. A Nabi technician will inspect that area, correct the contact point, and confirm the cover latch no longer rubs or strikes the cylinder. The final dealer repair will be free once available, with parts and labor covered under the recall. The remedy text does not give a repair time, so ask the service desk how long the bus needs to stay in the shop.

Recall 14V143 covers 241 2013-2014 Nabi 40LFW, 35LFW, and 31LFW transit buses with CNG fuel systems. A latch assembly bolt can contact the CNG fuel cylinder, damage the cylinder, and create a fuel leak that increases fire risk.
What should I do if my 2013-2014 Nabi 40LFW, 35LFW, or 31LFW is on this recall?
Check your VIN to confirm your specific bus is included in recall 14V143. If it is, contact a franchised Nabi dealer and ask for the CNG top cover latch interference repair. Reference recall number 14V143 and Nabi recall number 20142 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. Nabi dealers will eliminate the possible interference between the latch assembly bolt and the CNG fuel cylinder free of charge.
