Recalls, owner-reported complaints, investigations and safety data
Our database contains no NHTSA owner-reported complaints for the 2009 Oshkosh S-Series. 11 manufacturer communications are on file.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.
No recalls in our database for this model year
That does not guarantee a specific vehicle is unaffected — recalls are issued against VINs, and new campaigns are announced regularly. Check a VIN on NHTSA.gov.
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.
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
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
FUEL SYSTEM, OTHER:FUEL FILTER
This bulletin provides instruction for installing a hydraulic system charge pump filter.
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.
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.
POWER TRAIN
This bulletin provides information for vehicle owners that have a Dana series 172 or 175 rear axle without a lubricant drain plug in the bottom of the axle housing.
POWER TRAIN
This bulletin provides instruction for replacing the mixer pump PTO shaft, mixer pump input yoke, and mixer pump input yoke bearing U-bolts to the current production configuration. The new PTO shaft is larger with greaseable crosses and requires a new mixer pump input yoke and replacing the input yoke bearing U-bolts with bearing straps.
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.
