Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor. The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
Authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall is scheduled to begin by mid-April.
Customers may contact Paccar at (425) 468-7400. Paccar's recall numbers associated with this campaign are 14KWG for Kenworth and 214-C for Peterbilt.

The bolts used to mount the steering gear to the frame may fail, resulting in either looseness of steering or the loss of steering, which could increase the risk of a crash.
Navistar has notified owners, and dealers will inspect and replace the bolts as necessary, free of charge. The recall began on Feb. 19, 2014.

In the affected vehicles, the Engine Warning Protection Shutdown was inadvertently re-enabled when the Engine Control Module was recalibrated. If the Engine Warning Protection System is enabled and certain engine faults occur, the emergency vehicle may shutdown hampering rescue operations and increasing the risk of injury.
Navistar will notify owners, and dealers will recalibrate the ECM software to ensure that the EWPS is disabled, free of charge. The recall is expected to begin around March 19. Navistar's recall number for this campaign is 14505.
