Oshkosh Corporation (Oshkosh) is recalling certain Bendix Pressure Switches, part number 4133101, sold as aftermarket parts. 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.
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 will notify owners, and dealers will inspect the brake pressure valve, and if necessary, replace it, free of charge. The recall began September 30, 2020. Owners may contact Oshkosh customer service at 1-888-686-7278.
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.
