Nabi 40LFW Recall 15V485: Fuel tank relief valve may fail, risking tank explosion

NHTSA campaign 15V485, reported August 4, 2015, 70 vehicles potentially affected.

What this recall means for you

Certain transit buses powered by compressed natural gas (CNG) may have pressure relief devices that do not work as designed. These devices are meant to vent built-up pressure from the fuel tank, for example if the tank is exposed to fire. If the device fails to open, the CNG tank could explode, increasing the risk of fire and injury.

The recall covers certain 2014 and 2015 model year buses built during specific production windows in 2014 and 2015. If you operate or ride in one of these vehicles, contact New Flyer Industries customer service at 1-204-224-1251 and reference recall number R15-012. Check your vehicle identification number (VIN) for open recalls to confirm whether your bus is affected.

New Flyer has notified owners, and Agility, the supplier of the CNG system, will replace the pressure relief devices free of charge. The recall began on August 17, 2015.
