United States 18V581000
Daimler Trucks North America, LLC
The problem
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.
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.
What owners should do
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.
