Risk: Excessively hot battery ground cables may cause personal injury during battery maintenance repairs. In addition, a battery post that separates from the battery can result in an engine stall without warning, increasing the risk of a crash.

Fix: Dealers will replace the alternator positive and ground cables, and relocate the alternator ground to the starter, free of charge. Owner notification letters are expected to be mailed September 26, 2022. Owners may contact Navistar's customer service at 1-800-448-7825. Navistar's number for this recall is 22516.

Defect: Navistar, Inc. (Navistar) is recalling certain 2019 International HX, DuraStar, WorkStar, HV, LoneStar, LT, MV, and RH vehicles, and IC Bus HC, CE, and RE vehicles equipped with long stroke brake chambers and spring actuated parking brakes. The spring actuated parking brake may be improperly crimped to the long stroke service brake chamber, causing a service brake air leak and the possible separation of the spring brake chamber from the service brake section.

Risk: An air leak or separation of the spring brake chamber can increase the needed stopping distance, increasing the risk of a crash.

Fix: Navistar will notify owners, and dealers will replace the brake chamber assemblies from the suspected lot, free of charge. The recall began October 23, 2018. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 18512.

Engine And Engine Cooling:engine:diesel 2018-09-05 · campaign 18V588000 · 26,288 vehicles

Defect: 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.

Fix: 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.

The front driver and passenger seat belt anchor D-ring bolt may break in the event of a crash.

Risk: If the D-ring bolt breaks during a crash, the seat occupant may not be properly restrained, increasing their risk of injury.

Fix: Navistar has notified owners, and dealers will replace the D-ring bolt depending on the information found on the seat belt label, free of charge. The recall began May 23, 2018. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 18505.
