Complaints by model year
Newer model years have had less time on the road, so they naturally have fewer complaints. Compare a year against its neighbors rather than against brand-new models.

Oshkosh S-Series recalls
Risk: Front axle failure can cause a sudden loss of vehicle handling and control, increasing the risk of a crash.
Risk: A pedal that sticks increases the risk of a crash.
Risk: Damaged alternator electrical cables can increase the risk of a fire.
Risk: Bolt failure may allow the front axle to shift or detach, increasing the risk of a crash.
Risk: A high pressure fuel leak in the presence of an ignition source may increase the risk of a fire.
Risk: A loss of power steering assist increases the risk of a crash.
Risk: The incorrectly sized fuse may blow during an ABS braking event, increasing the risk of a crash.
Risk: A detached axle may cause a loss of vehicle control, increasing the risk of a crash.
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.
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.
Risk: Loss of hydraulic assist steering may make it difficult to steer the vehicle, increasing the risk of a crash.
Risk: Strobe lights in this location may be wrongly interpreted when signaling others, increasing the risk of crash.
Risk: The forcible ejection of the stem may increase the risk of injury to those nearby. Additionally, the unintended release of CNG can increase the risk of a fire.
Risk: An engine stall can increase the risk of a crash.
Risk: 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.
Risk: If the mounting bolts loosen, the bolts on the torque converter bolt flange may shear, resulting in a sudden loss of drive power, and increasing the risk of a crash.
Risk: If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
Risk: 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.
Risk: 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.
Risk: 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.
