What this recall means for you

Certain 2014-2015 S-Series concrete mixers powered by compressed natural gas (CNG) may have pressure relief devices that do not work as designed. If the CNG tank is exposed to fire and pressure builds up, the relief device may not activate to vent that pressure, and the tank could explode, increasing the risk of fire and injury.

Oshkosh will notify affected owners. Authorized dealers will inspect and replace the pressure relief devices as needed, at no charge to the owner. Owners may contact Oshkosh customer service at 1-888-686-7278 and should reference recall number 15E-059. You can also check your vehicle identification number (VIN) for any open recalls.
