Plain-English summary
Daimler Trucks North America LLC is recalling certain model year 2009-2015 Thomas Built Saf-T-Liner HDX school buses manufactured between February 25, 2008, and February 11, 2014. These vehicles are equipped with Cummins Westport Model ISL G engines. The recall affects 727 units.
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. A malfunctioning sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, which increases 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 April 12, 2014. Customers may contact Daimler at 1-800-385-4357 or Cummins Inc. at 1-800-343-7357. Daimler's number for this recall is FL-660. Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
