PACCAR Incorporated (PACCAR) is recalling certain model year 2015 Kenworth K270 and K370 trucks manufactured February 4, 2014, to October 10, 2014, and 2014-2015 Peterbilt 220 trucks manufactured December 5, 2013, to October 10, 2014, equipped with certain 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.
PACCAR will notify owners, and dealers will and replace the valves, free of charge. The recall began on December 30, 2014. Owners may contact PACCAR customer service at 1-425-468-7400.
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.
