ENGINE AND ENGINE COOLING:ENGINE

Issued by Mack Trucks, Inc. · Reported Mar 24, 2014 · 1,934 vehicles affected

What's wrong

Mack Trucks Inc. (Mack) is recalling certain model year 2014-2015 CXU, 2010-2015 LEU, and 2011-2015 MRU vehicles manufactured with certain Cummins Westport Model ISL G and ISX12 G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.

Consequence

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.

Remedy

Cummins and Cummins Westport will notify owners, and 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.
