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."

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.

STEERING

Navistar, Inc. (Navistar) is recalling certain 2016 International DuraStar, LoneStar, ProStar, TerraStar, TranStar, WorkStar, 9900i, and IC Bus HC vehicles equipped with certain Spicer D or E series steer axles. The castellated nut on the steer axles may not be properly torqued, allowing the tie rod to loosen.

Risk: If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering, increasing the risk of a crash.

ENGINE AND ENGINE COOLING:ENGINE:DIESEL

Navistar Inc. (Navistar) is recalling certain model year 2016 International ProStar trucks manufactured August 5, 2015, to August 14, 2015, DuraStar trucks manufactured August 7, 2015, to August 13, 2015, Paystar trucks manufactured August 11, 2015, to August 14, 2015, and LoneStar trucks manufactured August 10, 2015, to August 14, 2015. In the affected vehicles, the Engine Control Module (ECM) may short circuit, causing the engine to stall without warning.

Risk: An engine that stalls without warning increases the risk of a crash.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

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.

Risk: 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.
