Daimler Trucks North America LLC (Daimler) is recalling certain model year 2014-2015 Freightliner 122SD, Argosy, and Cascadia trucks manufactured July 22, 2013, to October 13, 2014, equipped with Wabco Quick Release Valves with Double Check manufactured February 6, 2013, to April 19, 2014. The affected vehicles may have been produced with a defective valve seat installed.
Improper seating can result in the valves improperly adjusting air pressure levels, thereby reducing the braking performance of the vehicles and increasing the risk of a crash.
Daimler will notify owners, and dealers will inspect, and replace the valves, free of charge. The recall began on December 30, 2015. Owners may contact Daimler customer service at 1-800-745-8000. Daimler's number for this recall is FL-673.
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.
