Haldex Inversion Relay Valve: Service Brakes, Air recall

NHTSA campaign 24E011000 · 2,493 units potentially affected · filed Feb 9, 2024

What's wrong

ZF North America, Inc. (ZF) is recalling certain park brake actuation air brake systems equipped with Haldex inversion relay valves, part numbers 9718990020 and RKN28032. An internal piston in the inversion valve may fail, delaying the engagement of the parking brake. As such, these valves fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Why it matters

Delayed parking brake engagement can result in unintended vehicle movement, increasing the risk of a crash.

The fix

ZF will replace aftermarket equipment, free of charge. Affected vehicle manufacturers will determine the appropriate remedy for their vehicles. Owner notification letters were mailed April 9, 2024. Owners may contact ZF customer service at 1-734-416-6200.

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.
