2020 OSHKOSH S-SERIES Complaints and Recall Information
The 2020 OSHKOSH S-Series has 0 complaints and 13 recalls filed with NHTSA. Owners most frequently report issues related to various system recalls, with no formal complaints recorded. No direct owner-reported malfunctions or failures have been documented.
There are multiple recalls impacting suspension, fuel system, powertrain, electrical wiring, steering, brake lighting, parking brake, and air brake systems. These recalls address potential safety defects that may increase the risk of crashes or injuries, but currently no "Do Not Drive" or "Park Outside" advisories have been issued.
- Suspension u-bolt failure. Recall 22V009000 covers 1,268 vehicles where front axle u-bolts may fail, allowing the axle to shift or detach and increasing crash risk. Replacement u-bolts are provided free of charge.
- Fuel rail leaks. Recall 22V008000 affects 1,608 vehicles due to cracked fuel tubes between the fuel rail and injectors that may leak high-pressure fuel, raising fire risk. Dealers will install vibration isolators or replace tubes depending on mileage.
- Rear output shaft fracture. Recall 21V125000 involves 19 vehicles with potentially improperly heat-treated rear axle output shafts that could fracture, possibly detaching driveline components and increasing crash risk. Inspection and replacement will be done free.
- Incorrect ABS fuses. Recall 21V482000 affects 897 vehicles equipped with 10 amp ABS fuses instead of 15 amp, risking fuse blowout during braking and elevated crash risk. Owners will receive new fuses and installation instructions.
- Power steering pump defect. Recall 21V851000 covers 697 vehicles with a machining defect in the power steering pump that may cause pressure buildup and loss of power assist, increasing crash risk. Inspection and replacement are available at no charge.
- Brake pressure switch failure. Recall 20V499000 spans 172 vehicles where plastic threads in brake pressure switches may strip, causing air leaks that reduce braking effectiveness and disable brake lights, raising crash risk. Switches will be inspected and replaced as needed.
Owners with repeated repairs or ongoing recall-related safety defects may have rights under their state’s lemon law. Those affected should consult appropriate legal resources to understand potential remedies.

2020 OSHKOSH S-SERIES
1268 vehicles affected
SUSPENSION:FRONT:SPRINGS:LEAF SPRING ASSEMBLY:U-BOLT, LEAF SPRING TO AXLE
Oshkosh Corporation (Oshkosh) is recalling certain 2019-2022 S-Series vehicles. The u-bolts securing the front axle may fail.
Risk: Bolt failure may allow the front axle to shift or detach, increasing the risk of a crash.
2020 OSHKOSH S-SERIES
1608 vehicles affected
FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL
Oshkosh Corporation (Oshkosh) is recalling certain 2019-2022 S-Series vehicles. The fuel tubes between the fuel rail and the injector for cylinders 4, 5 and 6 may be susceptible to cracking, resulting in a high pressure fuel leak.
Risk: A high pressure fuel leak in the presence of an ignition source may increase the risk of a fire.
2020 OSHKOSH S-SERIES
19 vehicles affected
POWER TRAIN:MANUAL TRANSMISSION:INTERNAL:SHAFT:OUTPUT
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.
Risk: A fractured rear output shaft may cause the shaft or interaxle driveline to detach from the vehicle, increasing the risk of a crash or injury.
2020 OSHKOSH S-SERIES
697 vehicles affected
STEERING:HYDRAULIC POWER ASSIST:PUMP
Oshkosh Corporation (Oshkosh) is recalling certain 2020-2021 S-Series vehicles. A machining defect may cause pressure to build in the power steering pump and break the shaft seal, resulting in a loss of power steering assist.
Risk: A loss of power steering assist increases the risk of a crash.
2020 OSHKOSH S-SERIES
897 vehicles affected
ELECTRICAL SYSTEM:WIRING:FUSES AND CIRCUIT BREAKERS
Oshkosh Corporation (Oshkosh) is recalling certain 2019-2022 S-Series vehicles. These vehicles were manufactured with 10 amp Anti-Lock Brake System (ABS) fuses, instead of the required 15 amp ABS fuses.
Risk: The incorrectly sized fuse may blow during an ABS braking event, increasing the risk of a crash.
2020 OSHKOSH S-SERIES
172 vehicles affected
SERVICE BRAKES, AIR
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.
Risk: As a result of a pressure switch air leak, the braking distance may be diminished and/or the parking brake may automatically engage. If the vehicle is equipped with an affected brake switch on both the front and the rear brakes and both parts fail, the brake lights may not operate. These conditions may increase the risk of a crash.
