2013 Nabi LFW problems

What is wrong

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.

Risk

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.
