- 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
- 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.
- 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.
- Notes

Has your Oshkosh been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Oshkosh dealer can also check your VIN. Recall repairs are free.
