NHTSA's recall notice
As NHTSA's recall record states it for campaign 15V641000.
Defect description
Paccar Incorporated (Paccar) is recalling certain model year 2012-2013 Peterbilt 579 and 587 trucks manufactured February 14, 2011, to December 5, 2012 and 2011 Kenworth T700 trucks manufactured September 21, 2010, to October 1, 2010. The affected trucks are equipped with Fontaine Ultra LT Fifth Wheel connectors, which, due to cumulative damage to the fifth wheel and its locking mechanism, have a locking mechanism that may fail to operate or to properly engage.
Safety consequence
If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.
Manufacturer remedy
PACCAR will notify owners, and dealers will replace the fifth wheel with an Ultra NT model fifth wheel, free of charge. The recall began on December 7, 2015. Owners may contact Kenworth customer service at 1-425-828-5000 or Peterbilt customer service at 1-940-591-4000. Paccar's numbers for this recall are 15KWP (Kenworth) and 1015M (Peterbilt).
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.
