The defect
Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2019 Freightliner Cascadia, Coronado and 122SD, and Western Star 4900 trucks, equipped with Cummins ISX15 or X15 diesel engines. In certain driving conditions, such as on a long down-hill grade, the fuel line may burst if the fuel pump cooling circuit screen becomes restricted.
The risk
If the fuel line bursts, fuel may leak onto the road resulting in a roadway hazard for other motorists. The engine may also stall without warning, resulting in the vehicle's inability to restart, increasing the risk of a crash.
The remedy
Dealers will replace the affected nylon fuel line with a steel fuel line, free of charge. The recall began November 21, 2018. Owners may contact DTNA customer service at 1-800-547-0712 or Cummins customer service at 1-800-286-6467. DTNA's number for this recall is FL789.
