Engine and engine cooling: engine: dieselReported September 5, 2018 · 26,288 vehicles affected

What is wrong: 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.
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.
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.
