Manufacturer: OSHKOSH CORPORATION
Manufacturer Campaign Number: Emcara: 15E-059
Manufactured Begin Date: July 16th, 2014
Manufactured End Date: June 30th, 2015
Date of Owner Notification: September 25th, 2015

Defect Summary:
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.

Consequence Summary:
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.

Corrective Summary:
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.

NHTSA Campaign Number: 15V412000
Manufacturer: OSHKOSH CORPORATION
Manufactured Begin Date: February 10th, 2015
Manufactured End Date: March 20th, 2015
Date of Owner Notification: May 8th, 2015

Defect Summary:
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.

Consequence Summary:
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.

Corrective Summary:
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.

Recall Notes:
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Manufactured Begin Date: September 24th, 2013
Manufactured End Date: November 12th, 2014

Defect Summary:
Oshkosh Corporation (Oshkosh) is recalling certain model year 2014-2015 S-Series Front Discharge Concrete Mixer vehicles manufactured September 24, 2013, to November 12, 2014.

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.

Corrective Summary:
Oshkosh will notify owners and dealers will install a larger capacity air tank, free of charge. The recall began April 15, 2015. Owners may contact Oshkosh customer service at 1-888-686-7278. Oshkosh's number for this recall is VSR-TSB-010.
