Plain-English summary

Mack Trucks, Inc. is recalling certain model year 2014-2015 CXU, 2010-2015 LEU, and 2011-2015 MRU vehicles. These vehicles were manufactured with certain Cummins Westport Model ISL G and ISX12 G engines. The recall involves 1,934 vehicles.

The defect involves condensation in the intake manifold that may freeze during cold weather conditions. This freezing can interfere with the proper operation of the intake manifold pressure sensor. 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.

Cummins and Cummins Westport will notify owners. Authorized Cummins service facilities will upload a new ECM calibration free of charge. The recall began on March 12, 2014. Customers may contact Mack at 1-336-393-2000 or Cummins Inc. at 1-800-343-7357. Mack's number for this recall is SC0377.
