NHTSA's recall notice
As NHTSA's recall record states it for campaign 13V573000.
Defect description
PACCAR is recalling certain model year 2007-2014 Kenworth T800 and W900 trucks manufactured March 22, 2006, through July 15, 2013 and equipped with Primaax tridem rear suspensions and a pusher and/or tag axle. The affected trucks have brake chambers that take longer to apply or release the brakes than the required time limit. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."
Safety consequence
Brakes that take longer to apply may lengthen the distance needed to stop the truck, increasing the risk of a crash.
Manufacturer remedy
PACCAR will notify owners, and dealers will modify the air brake system, free of charge. The recall began on January 15, 2014. Owners may contact PACCAR at 1-425-468-7400. Kenworth's recall number is 13KWL.
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.
