Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Feb 15, 2019
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

EXTERIOR LIGHTING

Feb 15, 2019
241 units potentially affected
The defect: 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."
The risk: Strobe lights in this location may be wrongly interpreted when signaling others, increasing the risk of crash.
The remedy: Oshkosh will notify owners, and replace the strobe lamp with a steady burning lamp, free of charge. The recall began April 10, 2019. Owners may contact Oshkosh customer service at 1-888-686-7278.

FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY:PRESSURE RELIEF DEVICES

Aug 20, 2015
33 units potentially affected
The 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.
The 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.
The 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.

POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER

Jun 30, 2015
24 units potentially affected
The defect: 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.
The 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.
The remedy: Oshkosh has notified owners, and Valley Truck Parts will remove the paint from the mating surface of the torque converter, and replace the bolts, free of charge. The recall began on May 8, 2015. Owners may contact Oshkosh customer service at 1-888-686-7278.

Recent owner complaints

Reports submitted to NHTSA, shown in the owner's own words

No owner complaints recorded for this model year

Either none have been filed with NHTSA, or this vehicle is too new for reports to have accumulated.

Manufacturer communications

A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.

FDM-TSIB-046

SUSPENSION

This bulletin provides instructions for installing new updated front shock absorbers and upper mounting brackets. The updated shock absorber and mounting bracket lowers the top of the shock absorber improving the allowable maximum travel of the front leaf spring pack and keeps the shock absorber in its normal travel zone reducing the time the shock absorber is in hydraulic rebound

FDM_TSIB-047

EQUIPMENT

This bulletin provides instructions for installing rubber hose STAUFF clamps in areas of the vehicle that have hard line STAUFF clamps installed on rubber hoses. Rubber hose STAUFF clamps have a smooth inner contact surface and filleted edges. Installing rubber hose STAUFF clamps will reduce potential hose chaffing in areas where hard line clamps were installed

FDM-SVC-030

FUEL SYSTEM, OTHER:FUEL FILTER

This bulletin provides instruction for installing a hydraulic system charge pump filter.

FDM-TSIB-043

EQUIPMENT

This bulletin provides information on updating hydraulic hose clamping below the cab to match current production. Engineering recommends changing out the front STAUFF clamp using the following procedure. The second STAUFF clamp can be changed out using this procedure if desired.

FDM-TSIB-041

POWER TRAIN

This bulletin provides information on topics specific to transmission high temperature warnings reported in the field. The topics listed were helpful in preventing transmission high temperature warning conditions.

FDM-SVC-002

EQUIPMENT

This bulletin provides instruction for replacing the water pump impeller due to corrosion. Oshkosh has received reports of non-working water pumps due to the pump impeller becoming corroded and seized, causing the pump not to spin. A new impeller made of an improved alloy was developed to eliminate corrosion issues.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
