2014 International Lonestar problems

Defect

Navistar, Inc. is recalling certain model year 2013-2014 International ProStar and DuraStar trucks manufactured April 26, 2012, to April 4, 2013, WorkStar trucks manufactured April 27, 2012, to March 29, 2013, LoneStar trucks manufactured May 21, 2012, to April 2, 2013, and TranStar trucks manufactured April 30, 2012, to March 25, 2013. In the affected vehicles, the accelerator pedal position sensor can move and result in a high engine idle.

Consequence

A high engine idle may make downshifting the transmission difficult and the engine brake may be disabled. These factors may hinder slowing down the truck when descending a long grade, thereby increasing the risk of a crash.

Remedy

Navistar will notify owners, and dealers will recalibrate the electronic control module (ECM) to allow it to recognize that the pedal is at the idle position, free of charge. The recall began on January 19, 2016. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 15517.

Defect

Navistar, Inc. (Navistar) is recalling certain model year 2011-2014 International ProStar trucks manufactured May 18, 2010, to April 5, 2013, 2012-2014 International LoneStar trucks manufactured September 7, 2011, to March 25, 2013, and 2011-2013 International TranStar trucks manufactured October 18, 2010, to February 20, 2013. The affected trucks are equipped with Fontaine Ultra LT Fifth Wheel connectors, which, due to cumulative damage to the fifth wheel and its locking mechanism, have a locking mechanism that may fail to operate or to properly engage.

Consequence

If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.

Remedy

Navistar will notify owners, and Fontaine dealers will replace the fifth wheel with an Ultra NT model fifth wheel, free of charge. The recall began on November 18, 2015. Owners may contact Navistar customer service at 1-800-448-7825, or Fontaine customer service at 1-844-597-7393.

Defect

Navistar, Inc. (Navistar) is recalling certain model year 2011-2015 International DuraStar, ProStar, TranStar and WorkStar, 2012-2015 International TerraStar, 2013-2015 International LoneStar and IC Bus HC, and 2014-2015 IC Bus AC vehicles. A vehicle double battery jump start or electrical load dump event could result in an overvoltage condition of a component within the HVAC system linear power module (LPM) which is used to control the blower speed. The overvoltage condition could result in the overheating and failure of the LPM.

Consequence

If the LPM overheats and fails, there is an increased risk of a fire.

Remedy

Navistar will notify owners, and dealers will replace the LPM with an upgraded one, free of charge. An interim letter was mailed to owners on June 18, 2015. A second notification will mailed when parts become available. The recall began on August 6, 2015. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 15509.

Defect

Navistar, Inc. (Navistar) is recalling certain model year 2010-2015 International Lonestar vehicles manufactured October 12, 2009, to June 16, 2014, and 2009-2015 International ProStar vehicles manufactured December 16, 2008, to June 20, 2014. In the affected vehicles the electrical harness that supplies power to the HVAC system may not be of sufficient size for the electrical load of the circuit. This can result in an increase in resistance and heating at the connectors.

Consequence

An increase in resistance and heating at the connectors could cause a vehicle fire.

Remedy

Navistar will notify owners, and dealers will replace the 60 amp relay and battery harness with a 150 amp relay and battery harness, free of charge. Navistar issued an interim notification to owners on December 29, 2014. The recall began on March 2, 2015. Owners may contact Navistar customer service at 1-331-332-1590.
