Two more truck makers have announced how many of their vehicles are affected by a recall announced in early March involving Cummins Westport powered natural gas engines.
Mack Trucks is recalling 1,934 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. This 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 and authorized Cummins service facilities will upload a new electronic control module calibration, free of charge. The manufacturer has not yet provided a notification schedule.
Customers may contact Mack at 1-336-393-2000 or Cummins at 1-800-343-7357.
Mack's number for this recall is SC0377.
The same recall applies to 426 Volvo Trucks including 2013-2015 VNL trucks, and 2013-2014 VNM trucks equipped with certain Cummins Westport Model ISL G and ISX12 G engines.
The manufacturer has not yet provided a notification schedule. Owners may contact Volvo at 1-800-528-6586.

Meantime, Paccar is recalling 474 2008-2013 Peterbilt 365, 367, 388, 389 trucks manufactured Oct. 6, 2007 through Sept. 23, 2013.
The affected vehicles were built with 16.5" x 7" front drum brakes and Bendix ES-420 brake linings installed on front axles rated to carry between 20,001 and 22,000 pounds, gross axle weight rating, and 20.5 inch to 21.5 inch tires. However, these brake linings are not rated for this configuration, meaning these vehicles fail to comply with Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
The improper brake configuration could lengthen the braking distance needed to stop the vehicle, increasing the risk of a crash.
Paccar will notify owners and dealers will install new 16.5" x 7" brake shoes with ES-600 linings, free of charge.
The recall is expected to begin in May 2014. Owners may contact at Peterbilt at 1-800-473-8372.
