NHTSA campaign 19V122000
Hazard
Navistar, Inc. (Navistar) is recalling certain 2016-2020 International LT and 2017-2018 Prostar 73-inch sleeper cab models equipped with feature code 07BKP or 07BKR (exhaust system with horizontal after treatment device and horizontal tailpipe mounted on right side). In the affected vehicles, the rear exhaust hanger bracket may crack, which can cause the forward hanger bracket to also crack. If both brackets crack, the exhaust tail pipe may detach from the vehicle.
Consequence
If the exhaust tail pipe detaches from the vehicle while being driven, it can become a road hazard, increasing the risk of crash.
Remedy
Navistar will notify owners, and dealers will replace the rear exhaust hanger bracket and replace any forward bracket found cracked and any exhaust tailpipe found damaged, free of charge. The recall began April 23, 2019. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 19501.
