NHTSA's recall notice
As NHTSA's recall record states it for campaign 15V329000.
Defect description
Navistar, Inc. (Navistar) is recalling certain model year 2015-2016 International 9900 trucks manufactured January 6, 2014, to March 12, 2015, and 2015-2016 International Lonestar trucks manufactured February 20, 2014, to March 13, 2015. The affected vehicles are equipped with a 6" diameter stack tail pipe, that may not have sufficient support. The unsupported weight of the upper stack tail pipe and vibration associated with normal vehicle operation over time may cause a crack of the weld joint between the inlet pipe and the flare expansion of the stack tail pipe, which may result in partial or full separation of the stack tail pipe from the vertical exhaust pipe.
Safety consequence
If the stack tail pipe separates from the exhaust pipe it can fall into the roadway possibly hitting another vehicle, increasing the risk of a crash.
Manufacturer remedy
Navistar will notify owners, and dealers will replace the stack tail pipe with a one piece stack tail pipe, free of charge. The recall began on July 20, 2015. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 15511.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
