NHTSA campaign 17V322000
Hazard
PACCAR Incorporated (PACCAR) is recalling certain 2012-2018 Kenworth T800 and T880 vehicles equipped with Neway ADZ tridem rear suspensions. The brake control airline may be the incorrect size, resulting in an imbalance in the service brake application timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air brake systems."
Consequence
An incorrectly sized airline may lengthen the distance needed to stop the vehicle, increasing the risk of a crash.
Remedy
Kenworth will notify owners, and dealers will modify the air brake system with updated brake piping, free of charge. The recall began on June 21, 2017. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 17KWB.
