Freightliner / Sterling / Thomas Built Buses recall: Engine and engine cooling
What is wrong
Daimler Trucks North America LLC (DTNA) is recalling certain model year 2007-2016 Freightliner 114SD and M2 Business Class trucks, 2008-2009 Sterling LT8500 trucks and Thomas Built Bus Saf-T-Liner HDX transit buses equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause 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.
What could happen
If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
The fix
Cummins will notify owners on behalf of DTNA, 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 DTNA customer service at 1-800-745-8000 or Cummins customer service at 1-800-343-7357. DTNA's number for this recall is FL-681.
