Reported: 2017-08-14 (August 14, 2017)

Navistar Inc. (Navistar) is recalling certain 2018 International LT and HX severe service diesel trucks equipped with Cummins ISX 15L engines. These engines have a fuel pump whose drive gear could possibly slip on its drive shaft, causing a fuel pump function loss, resulting in an engine stall.

Consequence: An engine stall can increase the risk of a crash.

Remedy: Cummins has notified the owners of the affected vehicles and Cummins dealers will replace the fuel pumps, free of charge. The recall began on August 11, 2017. Owners may contact Cummins customer service at 1-800-286-6467 or Navistar customer service at 1-331-332-1590.

Navistar, Inc. (Navistar) is recalling certain 2017-2019 International HX severe service diesel trucks equipped with feature code 04091 (dual air brake system) and 04AZY (Antilock Brake System (ABS) with 6 channel Electronic Stability Protection (ESP)). The air supply line to the SR7 roll stability valve may have been improperly routed to the ATR6 brake control valve steer axle delivery port, when it should be connected to the ATR6 brake control valve control port.

Consequence: During a stability control oversteer event when there are slippery road conditions, the parking brakes may be modulated unintentionally, potentially causing a loss of control and increasing the risk of a crash.

Remedy: Navistar will notify owners, and dealers will reroute the SR7 roll stability valve supply line to the ATR6 brake control valve control port, free of charge. The recall began on June 12, 2018. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 18504.

Reported: 2018-06-18 (June 18, 2018)

Navistar, Inc. (Navistar) is recalling certain 2018-2019 International HX and LT trucks equipped with a Cummins ISX engine and a Wabco 37.4 air compressor. The air compressor discharge line may contact the fuel filter inlet and outlet lines (fuel lines) and the heat generated from the air compressor discharge line may cause heat damage to the fuel lines.

Consequence: Continued heat damage to the fuel lines could cause the fuel lines to rupture, resulting in a fuel leak and increasing the risk of a fire.

Remedy: Navistar will notify owners, and dealers will replace the straight fitting on the air compressor discharge line and the discharge line with a 45-degree fitting and a redesigned discharge line, free of charge. The recall began on July 20, 2018. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 18511.

Reported: 2018-09-05 (September 5, 2018)

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.
