The short answer
NHTSA received Oshkosh Corporation’s report on Apr 1, 2015. Copied from NHTSA on Oct 19, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.
The affected vehicles have air tanks that hold less than the required 12 times the combined volume of the service brake chambers.
As a result, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, “Air Brake Systems.”
