NHTSA campaign 18V588000
Hazard
Navistar, Inc. (Navistar) is recalling certain 2017-2018 International ProStar and 9900i trucks, 2018-2019 International LT trucks, 2017-2019 International LoneStar and HX trucks and 2017 International PayStar 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.
Consequence
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.
Remedy
Cummins will notify the affected owners and dealers will replace the nylon fuel line with a steel fuel line, free of charge. Navistar issued owners an interim notification on October 11, 2018. The recall began November 21, 2018. Owners may contact Navistar customer service at 1-800-448-7825, or Cummins customer service at 1-800-286-6467.
