NHTSA's recall notice
As NHTSA's recall record states it for campaign 15V457000.
Defect description
PACCAR Incorporated (PACCAR) is recalling certain model year 2016 Kenworth T440, T470, T660, T680, T800, T880, and W900 trucks manufactured February 16, 2015, to March 9, 2015. The affected vehicles are equipped with an SR-7 spring brake valve assembly that may have had the primary and secondary service brake applications installed in reverse. In the event of a failure in the primary or secondary circuit, the redundant circuit would not provide adequate service brake functionality. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."
Safety consequence
A loss of braking ability would increase the risk of a crash.
Manufacturer remedy
Kenworth will notify owners, and dealers will inspect the vehicles and correct the air line installations as required, free of charge. The recall began on September 16, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 15KWK.
