Freightliner Business Class M2, 114SD: Engine
Affects Freightliner Business Class M2, 114SD · 2007–2016 — about 172 vehicles.
The hazard
On certain vehicles equipped with Cummins Westport ISL-G engines, excessive engine crankcase pressure could cause the vent tube assembly molded rubber adapter to detach from the breather. This could allow engine oil to come in contact with hot surfaces, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will install clamps at both ends of the adapter of the breather tube assembly and reprogram the Electronic Control Module (ECM) to improve diagnostic capabilities.
