May 06, 2021 – Oshkosh Corporation (Oshkosh) is recalling certain 2021 S-Series vehicles. The auxiliary axles may not have been properly secured and may detach.

Feb 26, 2021 – Oshkosh Corporation (Oshkosh) is recalling certain 2020-2021 S-Series vehicles. The rear axle output shaft may not have been heat-treated properly, which could cause the shaft to fracture.

Aug 24, 2020 – Oshkosh Corporation (Oshkosh) is recalling certain 2020 S-Series vehicles equipped with Bendix pressure switches. The plastic threads holding the two halves of the pressure switch may strip when the switch is pressurized, resulting in an air leak which, if severe enough, can cause the air system to lose pressure when the brakes are applied. Failure of the front and rear brake switches will also result in a loss of brake light functionality.

Jun 21, 2019 – Oshkosh Corporation (Oshkosh) is recalling certain 2018-2019 S-Series Mixer vehicles equipped with Cummins X12 engines with two hydraulic lines. The hydraulic hoses may have been unintentionally switched and installed to the wrong location, which can cause a loss of hydraulic assist steering.

Feb 15, 2019 – Oshkosh Corporation (Oshkosh) is recalling certain 2014-2019 S-Series Glider vehicles equipped with a strobe light package in the rear fender. The strobe lights may have been incorrectly located in the rear fender marker light position, potentially causing confusion for other drivers. As a result, the vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective devices, and associated Equipment."

Dec 03, 2018 – McNeilus Truck & Manufacturing, Inc. (McNeilus) is recalling certain 2016-2018 McNeilus Meridian Front Loader, Atlantic Front Loader, XE Rear Loader, Bridgemaster Mixer, Standard Mixer, and Oshkosh S-Series vehicles, equipped with certain MPVE-250 One-Turn Valves (OTV) on the CNG fuel tanks. If the valve knob is turned more than one turn, the valve's snap ring may fail and the valve stem may forcibly eject from the valve body.

Jun 08, 2016 – Oshkosh Corporation (Oshkosh) is recalling certain model year 2016 S-Series Front Discharge Concrete Mixers manufactured May 16, 2016, to May 25, 2016, equipped with a Cummins ISX12 or ISX15 engine using certain engine control modules (ECM). These ECM's may experience an internal electrical short that can cause a fuse to blow, resulting in an unexpected engine stall without the ability to restart the engine.

Aug 20, 2015 – 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.

Jun 30, 2015 – Oshkosh Corporation (Oshkosh) is recalling certain model year 2015 S-Series Front Discharge concrete mixer glider trucks manufactured February 10, 2015, to March 20, 2015. The affected vehicles have Allison HD4500 transmissions that were remanufactured by Valley Truck Parts that may be coated with a thick layer of paint on the torque converter to adaptation kit mounting surface which can soften during vehicle operation. This may result in the mounting bolts loosening.

Jun 01, 2015 – 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.
