Number of potentially involved : 4,717 Estimated percentage with defect : 10 % Equipment Information : Brand / Trade 1 :
Model : Haldex Inversion Valve Part No. : Multiple Size : NR Function : Brake System Ai
Descriptive Information : A defect in the inversion valve may cause the park brake engagement to be delayed. As such, vehicles may fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) 121, “Air Brake Systems”. If this condition exists, the park brake may not be applied within 3 seconds, resulting in inadvertent vehicle movement and a potential safety concern.
Production Dates : DEC 01, 2022 – MAY 05, 2023
Description of Defect :
Description of the Defect : An internal piston, incorporated into the inversion valve may have out of specification concentricity.
FMVSS 1 : 121 – Air brake systems FMVSS 2 : NR
Description of the Safety Risk : Failure of park brake to engage within 3 seconds.
Description of the Cause : Inversion valve piston fails to allow parking brake air pressure to vent. Identification of Any Warning
that can Occur : Vehicle movement more than 3 seconds after parking brake engagement.
