Issued by Daimler Buses North America · Reported Mar 5, 2014 · 455 vehicles affected

What's wrong

Daimler Buses North America (DBNA) is recalling certain model year 2007-2012 Orion VII transit buses manufactured January 2007 through October 2012 equipped with certain Cummins Westport Model ISL 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 Inc. and Cummins Wesport Inc. will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Owners may contact DBNA at 1-905-403-7807 or Cummins Inc. at 1-800-343-7357. Cummins' number for this recall is C1462 (for ISL G engines) or C1461 (for ISX12 G) engines.
