Fuel system, diesel08/19/201414V508000
NABI Bus, LLC (NABI) is recalling certain model year 2014 LFW and BRT transit buses manufactured May 2, 2014, to August 8, 2014. The Cummins ISB or ISL engines in these vehicles may have been equipped with Fleetguard UFF-XT fuel filters, part number FF63009, whose filter shell may separate from the fuel filter nut plate causing the engine to stall without warning.
Consequence
If the engine stalls unexpectedly, there is an increased risk of a crash.
Remedy
NABI will work with Cummins to notify owners, and Cummins service centers will install a new fuel filter, free of charge. The recall began in September 2014. Owners may contact NABI customer service at 1-256-831-4296 or Cummins customer service at 1-800-223-4583. NABI's number for this recall is 20144.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

NABI Bus, LLC (NABI) is recalling certain model year 2007-2015 LFW and BRT transit buses and 2007-2013 CLFW transit buses. Excessive engine crankcase pressures may cause the the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
Consequence
If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
Remedy
Cummins will work with NABI to notify owners, and dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact NABI customer service at 1-256-241-1298. NABI's number for this recall is 20152.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

NABI Bus, LLC (NABI) is recalling certain 2013-2014 LFW and BRT city transit buses manufactured January 1, 2013, through February 20, 2014, and equipped with certain Cummins Westport Model ISL G. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
Consequence
The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
Remedy
Cummins Inc. and Cummins Wesport Inc. will work with NABI and notify owners, and dealers will upload a new ECM calibration, free of charge. The recall began on April 21, 2014.
