ENGINE AND ENGINE COOLING:ENGINE
NHTSA #15V330000Reported June 1, 2015 · Oshkosh Corporation
Potentially affected: 44 vehicles
Defect description
Oshkosh Corporation (Oshkosh) is recalling certain model year 2012-2014 S-Series Front Discharge Concrete Mixer vehicles manufactured February 29, 2012, to November 13, 2013, and equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
Safety consequence
If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
Manufacturer remedy
Cummins will notify owners on behalf of Oshkosh, and dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Oshkosh customer service at 1-888-686-7278 or Cummins customer service at 1-800-343-7357.
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.

NHTSA #14V183000Reported April 7, 2014 · Oshkosh Corporation
Potentially affected: 46 vehicles
Defect description
Oshkosh Corporation (Oshkosh) is recalling certain model year 2012-2014 S-Series Ready Mixed Concrete trucks manufactured February 29, 2012, through January 27, 2014, and equipped with certain Cummins Westport Model ISL G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
Safety consequence
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.
Manufacturer remedy
Cummins Inc. and Cummins Wesport Inc. will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. Cummins Inc. and Cummins Westport Inc. began notifying the affected vehicle owners in April 2014. Owners may contact Oshkosh at 1-920-235-9150 or contact Cummins Inc. at 1-800-343-7357.

Potentially affected: 126 vehicles
Defect description
Oshkosh Corporation is recalling certain model year 2013 S-Series ready mixed concrete trucks manufactured May 1, 2013, through November 27, 2013. In the affected vehicles, the brake pedal bracket may loosen due to missing lock washers.
Safety consequence
A loose brake pedal bracket may allow the brake pedal to contact the floor of the cab, which would reduce the vehicle's braking capability and increase the risk of a crash.
Manufacturer remedy
