Oshkosh S-Series Recall 20V499: Air leak can cause loss of brakes and brake lights

NHTSA campaign 20V499, reported August 24, 2020, 172 vehicles potentially affected.

What this recall means for you

A pressure switch in the air brake system may have plastic threads that can strip when pressurized. This can cause an air leak that, if severe, may reduce braking distance or cause the parking brake to engage automatically. If both the front and rear brake switches fail, the brake lights may stop working as well. These conditions can increase the risk of a crash.

Oshkosh will notify owners, and authorized dealers will inspect the brake pressure switch and replace it if needed, at no charge. The recall began September 28, 2020. Owners can contact Oshkosh customer service at 1-888-686-7278.

If you own a 2020 S-Series vehicle, check your VIN for open recalls and contact an authorized dealer to schedule the free inspection and repair.

Component
EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH; PARKING BRAKE:CONVENTIONAL:AIR; SERVICE BRAKES, AIR
Problem
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.
Risk
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.
