The short answer
NHTSA received Oshkosh Corporation’s report on Aug 24, 2020. 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?
As a result of a pressure switch air leak, the braking distance may be diminished and/or the parking brake may automatically engage. If the vehicle is equipped with an affected brake switch on both the front and the rear brakes and both parts fail, the brake lights may not operate. These conditions may increase the risk of a crash.
Oshkosh Corporation (Oshkosh) is recalling certain 2020 S-Series vehicles equipped with Bendix pressure switches.
The plastic threads holding the two halves of the pressure switch may strip when the switch is pressurized, resulting in an air leak which, if severe enough, can cause the air system to lose pressure when the brakes are applied.
Failure of the front and rear brake switches will also result in a loss of brake light functionality.
