Defect: Oshkosh Corporation (Oshkosh) is recalling certain model year 2014-2015 S-Series concrete mixers manufactured July 16, 2014, to June 30, 2015. The affected concrete mixers are powered with compressed natural gas (CNG) and are equipped with pressure relief devices (PRD) that may not function as designed, failing to vent a buildup of pressure, such as could occur if the CNG tank was exposed to fire (excerpt)
Consequence: If the PRD does not activate in the event of a buildup of pressure, the CNG tank may explode, increasing the risk of fire and injury. (excerpt)
Remedy: Oshkosh will notify owners, and dealers will inspect and replace the PRD's, as necessary, free of charge. The recall began on September 25, 2015. Owners may contact Oshkosh customer service at 1-888-686-7278. Oshkosh's number for this recall is Emcara 15E-059. (excerpt)

Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engi (excerpt)
Consequence: If engine oil comes into contact with a hot surface, there is an increased risk of a fire. (excerpt)
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 custome (excerpt)

Defect: Oshkosh Corporation (Oshkosh) is recalling certain model year 2014-2015 S-Series Front Discharge Concrete Mixer vehicles manufactured September 24, 2013, to November 12, 2014. The affected vehicles have air tanks that hold less than the required 12 times the combined volume of the service brake chambers. As a result, these vehicles fail to comply with the requirements of Federal Motor Vehicle Sa (excerpt)
Consequence: With the air tank volume being less than required, in certain situations the vehicle may have an insufficient quantity of air to operate the brakes, increasing the risk of a crash. (excerpt)
Remedy: Oshkosh will notify owners and dealers will install a larger capacity air tank, free of charge. The recall began April 15, 2015. Owners may contact Oshkosh customer service at 1-888-686-7278. Oshkosh's number for this recall is VSR-TSB-010. (excerpt)

Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
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.
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.
