• Engine#2015211May 15, 2015

  169 units affected

  On certain vehicles equipped with Cummins Westport ISL-G engines, excessive engine crankcase pressure could cause the vent tube assembly elbow 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 elbow of the breather tube assembly and reprogram the Electronic Control Module (ECM) to improve diagnostic capabilities.

• Steering#2015078February 20, 2015

  574 units affected

  On certain vehicles, the tie rod end clamp bolts may not have been tightened to the correct specification. As a result, the tie rod ends could loosen, corrode, and eventually separate from the tie rod, resulting in a loss of steering control, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace tie rod assembly where the factory installed assembly has not been replaced.

• Fuel System#2014339August 7, 2014

  199 units affected

  On certain vehicles equipped with Cummins ISB and ISL engines, the fuel filter shell and nut plate could separate, causing a fuel leak and also causing the engine to stall. Stalling would result in a loss of motive power, increasing the risk of a crash resulting in injury and/or damage to property. Correction: Dealers will replace the fuel filter.

• Engine#2014046February 19, 2014

  82 units affected

  On certain vehicles equipped with Cummins ISL G or ISX12 G engines, incorrect engine ECU programming could cause the exhaust system temperature to become elevated during cold weather operation. This could also cause flames to be emitted from the exhaust. As a result, nearby combustible material could be ignited, increasing the risk of a fire, injury and/or damage to property. Correction: Authorized Cummins service facilities will update software programming.

  PACCAR Incorporated (PACCAR) is recalling certain 1990-2020 Peterbilt 320 and 520 vehicles built with specific amber rear turn signals.
