Daimler Trucks North America (DTNA) is recalling certain 2017-2018 Freightliner 122SD trucks, Western Star 4900 and 6900 trucks, and Freightliner Custom Chassis XCM and XCP chassis equipped with Cummins ISX15 engines. The affected engines have a fuel pump whose drive gear may slip on its drive shaft, resulting in a loss of fuel pump function.
Failure of the fuel pump will result in a sudden engine stall with no warning, and with no ability to restart, increasing the risk of a crash.
Cummins will send notices to the owners of the affected vehicles and Cummins dealers will replace the fuel pumps, free of charge. The recall began on September 11, 2017. Owners may contact Cummins customer service at 1-800-286-6467 or DTNA customer service at 1-800-745-8000. DTNA's number for this recall is FL744.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
