Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest May 18, 2023
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The defect: Navistar, Inc. (Navistar) is recalling certain 2000-2003 International 8100, 2001-2003 International 9100i, 2001-2007 International 9400i, 2001-2010 International 9200i, 2002-2007, 2009 International 8500, 2003-2007, 2013 International 9900i, 2003-2018 International 8600, 2004, 2007 International 9900iX, 2008-2018 International ProStar, 2010-2011, 2013, 2016 International LoneStar, 2011-2012, 2016 International 4400, 2017-2024 International LT, 2018-2024 International RH, 2019-2021 International LS, 2019-2024 International MV vehicles. The back-up lights offer low visibility when the vehicle is in reverse and bobtail mode. Also, the vehicles have not been equipped with additional unobstructed back-up lights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
The risk: Low visibility or obstructed back up lights may not alert other drivers that the vehicle is backing up, increasing the risk of a crash.
The remedy: Dealers will replace the existing rear stop/turn signal lights, free of charge. Owner notification letters were mailed May 06, 2024. Owners may contact Navistar's customer service at 1-800-448-7825. Navistar's number for this recall is 23514.

TRAILER HITCHES:FIFTH WHEEL ASSEMBLY

Sep 29, 2015
3,776 units potentially affected
The 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.
The risk: 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.
The 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.

ELECTRICAL SYSTEM

This tool is designed to compare Diamond Logic feature data across multiple vehicle configuration files. It allows users to quickly load files either manually or directly from the Diamond Logic Builder Vehicles folder using VIN-based selection. As files are added or removed, the comparison runs automatically with no manual action required. The program presents results in an interactive table that shows feature codes, descriptions, access levels, and whether each feature is present in each selected file. Built-in search, filtering, and sorting make it easy to locate specific features or focus only on differences between files. Column visibility can be customized to show or hide descriptions and access information as needed. Users can remove files individually or clear all files at once, with results updating instantly. The tool also includes reporting and export options that reflect exactly what is visible on screen, allowing results to be printed, copied, saved as text, or exported to CSV for use in Excel or other spreadsheet tools. Overall, the program streamlines the process of comparing vehicle feature configurations, helping users quickly identify differences, validate setups, and document results without manual comparison or external tools.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
