- Summary
- 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.
- Consequence
- 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.
- Remedy
- Oshkosh will notify owners, and dealers will inspect the brake pressure switch and replace it as necessary, free of charge. The recall began September 28, 2020. Owners may contact Oshkosh customer service at 1-888-686-7278.
- 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.

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.
